[PATCH] selftests: pmtu: use -oneline for ip route list cache
by Thadeu Lima de Souza Cascardo
Some versions of iproute2 will output more than one line per entry, which
will cause the test to fail, like:
TEST: ipv6: list and flush cached exceptions [FAIL]
can't list cached exceptions
That happens, for example, with iproute2 4.15.0. When using the -oneline
option, this will work just fine:
TEST: ipv6: list and flush cached exceptions [ OK ]
This also works just fine with a more recent version of iproute2, like
5.4.0.
For some reason, two lines are printed for the IPv4 test no matter what
version of iproute2 is used. Use the same -oneline parameter there instead
of counting the lines twice.

kselftest: failed to build with -C tool/testing/selftests when KBUILD_OUTPUT is set
by Cristian Marussi
Hi
while testing on linux-next
I see that, when KBUILD_OUTPUT is set in the env, running something like (using TARGETS=exec as a random subsystem here...)
$ make TARGETS=exec INSTALL_PATH=/nfs/LTP-official-debian-aarch64-rootfs/opt/KSFT_next kselftest-install
works fine as usual, WHILE the alternative invocation (still documented in Documentation/dev-tools/kselftest.rst)
make -C tools/testing/selftests/ TARGETS=exec INSTALL_PATH=/nfs/LTP-official-debian-aarch64-rootfs/opt/KSFT_next install
fails miserably with:
...
...
REMOVE usr/include/rdma/cxgb3-abi.h usr/include/rdma/nes-abi.h
HDRINST usr/include/asm/kvm.h

/home/crimar01/ARM/dev/src/pdsw/linux/Makefile:1187: recipe for target 'headers_install' failed
make[2]: *** [headers_install] Error 1
This is fixed by unsetting KBUILD_OUTPUT OR reverting:
303e6218ecec (ksft/fixes) selftests: Fix O= and KBUILD_OUTPUT handling for relative paths
since bypassing top makefile with -C, the definition of abs-objtree used by the above patch
is no more available.
As a side effect when KBUILD_OUTPUT is set, this breaks also the usage kselftest_install.sh.

A possible fix would be (but duplicates in fact the main Makefile logic)

Any thoughts ? ... or am I missing something ?
(I think I'm starting to see this in latest CI linaro kselftest while they cross-compile for arm64)
Thanks

selftests:netfilter: nft_nat.sh: internal00-0 Error Could not open file \"-\" No such file or directory

Do you see the following error while running selftests netfilter
nft_nat.sh test ?
Are we missing any kernel config fragments ? We are merging configs
from the directory.

[PATCH] fs/ext4/inode-test: Fix inode test on 32 bit platforms.
by Iurii Zaikin
Fixes the issue caused by the fact that in C in the expression
of the form -1234L only 1234L is the actual literal, the unary
minus is an operation applied to the literal. Which means that
to express the lower bound for the type one has to negate the
upper bound and subtract 1.

[PATCH] kunit: test: Improve error messages for kunit_tool when kunitconfig is invalid
by Heidi Fahim
Previous error message for invalid kunitconfig was vague. Added to it so
that it lists invalid fields and prompts for them to be removed. Added
validate_config function returning whether or not this kconfig is valid.

[PATCH v3 0/4] PM: QoS: Restore DEV_PM_QOS_MIN/MAX_FREQUENCY
by Leonard Crestez
Support for frequency limits in dev_pm_qos was removed when cpufreq was
switched to freq_qos, this series attempts to restore it by
reimplementing on top of freq_qos.
Discussion about removal is here:
https://lore.kernel.org/linux-pm/VI1PR04MB7023DF47D046AEADB4E051EBEE680@VI1…
The cpufreq core switched away because it needs contraints at the level
of a "cpufreq_policy" which cover multiple cpus so dev_pm_qos coupling
to struct device was not useful. Cpufreq could only use dev_pm_qos by
implementing an additional layer of aggregation anyway.
However in the devfreq subsystem scaling is always performed on a per-device
basis so dev_pm_qos is a very good match. Support for dev_pm_qos in devfreq
core is here:
https://patchwork.kernel.org/cover/11252409/
That series is RFC mostly because it needs these PM core patches.
Earlier versions got entangled in some locking cleanups but those are
not strictly necessary to get dev_pm_qos functionality.
In theory if freq_qos is extended to handle conflicting min/max values then
this sharing would be valuable. Right now freq_qos just ties two unrelated
pm_qos aggregations for min and max freq.
---
This is implemented by embeding a freq_qos_request inside dev_pm_qos_request:
the data field was already an union in order to deal with flag requests.
The internal freq_qos_apply is exported so that it can be called from
dev_pm_qos apply_constraints.
The dev_pm_qos_constraints_destroy function has no obvious equivalent in
freq_qos and the whole approach of "removing requests" is somewhat dubios:
request objects should be owned by consumers and the list of qos requests
should be empty when the target device is deleted.
Changes since v2:
* #define PM_QOS_MAX_FREQUENCY_DEFAULT_VALUE FREQ_QOS_MAX_DEFAULT_VALUE
* #define FREQ_QOS_MAX_DEFAULT_VALUE S32_MAX (in new patch)
* Add initial kunit test for freq_qos, validating the MAX_DEFAULT_VALUE found
by Matthias.
Link to v2: https://patchwork.kernel.org/cover/11250413/
First two patches can be applied separated
Changes since v1:
* Don't rename or EXPORT_SYMBOL_GPL the freq_qos_apply function; just
drop the static marker.

[PATCH v8 1/9] hugetlb_cgroup: Add hugetlb_cgroup reservation counter
by Mina Almasry
These counters will track hugetlb reservations rather than hugetlb
memory faulted in. This patch only adds the counter, following patches
add the charging and uncharging of the counter.
Problem:
Currently tasks attempting to allocate more hugetlb memory than is available get
a failure at mmap/shmget time. This is thanks to Hugetlbfs Reservations [1].
However, if a task attempts to allocate hugetlb memory only more than its
hugetlb_cgroup limit allows, the kernel will allow the mmap/shmget call,
but will SIGBUS the task when it attempts to fault the memory in.
We have developers interested in using hugetlb_cgroups, and they have expressed
dissatisfaction regarding this behavior. We'd like to improve this
behavior such that tasks violating the hugetlb_cgroup limits get an error on
mmap/shmget time, rather than getting SIGBUS'd when they try to fault
the excess memory in.
The underlying problem is that today's hugetlb_cgroup accounting happens
at hugetlb memory *fault* time, rather than at *reservation* time.
Thus, enforcing the hugetlb_cgroup limit only happens at fault time, and
the offending task gets SIGBUS'd.
Proposed Solution:
A new page counter named hugetlb.xMB.reservation_[limit|usage]_in_bytes. This
counter has slightly different semantics than
hugetlb.xMB.[limit|usage]_in_bytes:
- While usage_in_bytes tracks all *faulted* hugetlb memory,
reservation_usage_in_bytes tracks all *reserved* hugetlb memory and
hugetlb memory faulted in without a prior reservation.
- If a task attempts to reserve more memory than limit_in_bytes allows,
the kernel will allow it to do so. But if a task attempts to reserve
more memory than reservation_limit_in_bytes, the kernel will fail this
reservation.
This proposal is implemented in this patch series, with tests to verify
functionality and show the usage. We also added cgroup-v2 support to
hugetlb_cgroup so that the new use cases can be extended to v2.
Alternatives considered:
1. A new cgroup, instead of only a new page_counter attached to
the existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code
duplication with hugetlb_cgroup. Keeping hugetlb related page counters under
hugetlb_cgroup seemed cleaner as well.
2. Instead of adding a new counter, we considered adding a sysctl that modifies
the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do accounting at
reservation time rather than fault time. Adding a new page_counter seems
better as userspace could, if it wants, choose to enforce different cgroups
differently: one via limit_in_bytes, and another via
reservation_limit_in_bytes. This could be very useful if you're
transitioning how hugetlb memory is partitioned on your system one
cgroup at a time, for example. Also, someone may find usage for both
limit_in_bytes and reservation_limit_in_bytes concurrently, and this
approach gives them the option to do so.
Testing:
- Added tests passing.
- libhugetlbfs tests mostly passing, but some tests have trouble with and
without this patch series. Seems environment issue rather than code:

[PATCH 00/19] pin_user_pages(): reduced-risk series for Linux 5.5
by John Hubbard
Hi,
Here is a set of well-reviewed (expect for one patch), lower-risk items
that can go into Linux 5.5. The one patch that wasn't reviewed is the
powerpc conversion, and it's still at this point a no-op, because
tracking isn't yet activated.
This is based on linux-next: b9d3d01405061bb42358fe53f824e894a1922ced
("Add linux-next specific files for 20191122").
This is essentially a cut-down v8 of "mm/gup: track dma-pinned pages:
FOLL_PIN" [1], and with one of the VFIO patches split into two patches.
The idea here is to get this long list of "noise" checked into 5.5, so
that the actual, higher-risk "track FOLL_PIN pages" (which is deferred:
not part of this series) will be a much shorter patchset to review.
For the v4l2-core changes, I've left those here (instead of sending
them separately to the -media tree), in order to get the name change
done now (put_user_page --> unpin_user_page). However, I've added a Cc
stable, as recommended during the last round of reviews.
Here are the relevant notes from the original cover letter, edited to
match the current situation:
This is a prerequisite to tracking dma-pinned pages. That in turn is a
prerequisite to solving the larger problem of proper interactions
between file-backed pages, and [R]DMA activities, as discussed in [1],
[2], [3], and in a remarkable number of email threads since about
2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()

[PATCH] selftests: Load settings from subdirs
by Kees Cook
If settings files are present in upper directories of a test directory,
load those first before the local settings. This allows a top-level
directory to define settings for subdirectories while still allowing the
subdirectories to override them on a per-directory basis.
Signed-off-by: Kees Cook <keescook(a)chromium.org>

Note that this depends on Matt's patch:

+kunit_tool How-To
+=================
+
+What is kunit_tool?
+===================
+
+kunit_tool is a script (``tools/testing/kunit/kunit.py``) that aids in building
+the Linux kernel as UML (`User Mode Linux
+<http://user-mode-linux.sourceforge.net/>`_), running KUnit tests, parsing
+the test results and displaying them in a user friendly manner.
+
+What is a kunitconfig?
+======================
+
+It's just a defconfig that kunit_tool looks for in the base directory.
+kunit_tool uses it to generate a .config as you might expect. In addition, it
+verifies that the generated .config contains the CONFIG options in the
+kunitconfig; the reason it does this is so that it is easy to be sure that a
+CONFIG that enables a test actually ends up in the .config.
+
+How do I use kunit_tool?
+=================================
+
+If a kunitconfig is present at the root directory, all you have to do is:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run
+
+However, you most likely want to use it with the following options:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all`
+
+- ``--timeout`` sets a maximum amount of time to allow tests to run.
+- ``--jobs`` sets the number of threads to use to build the kernel.
+
+If you just want to use the defconfig that ships with the kernel, you can
+append the ``--defconfig`` flag as well:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all` --defconfig
+
+.. note::
+ This command is particularly helpful for getting started because it
+ just works. No kunitconfig needs to be present.
+
+For a list of all the flags supported by kunit_tool, you can run:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --help

[PATCH v4 linux-kselftest-test 0/6] kunit: support building core/tests as modules
by Alan Maguire
The current kunit execution model is to provide base kunit functionality
and tests built-in to the kernel. The aim of this series is to allow
building kunit itself and tests as modules. This in turn allows a
simple form of selective execution; load the module you wish to test.
In doing so, kunit itself (if also built as a module) will be loaded as
an implicit dependency.
Because this requires a core API modification - if a module delivers
multiple suites, they must be declared with the kunit_test_suites()
macro - we're proposing this patch set as a candidate to be applied to the
test tree before too many kunit consumers appear. We attempt to deal
with existing consumers in patch 3.
Changes since v3:
- removed symbol lookup patch for separate submission later
- removed use of sysctl_hung_task_timeout_seconds (patch 4, as discussed
with Brendan and Stephen)
- disabled build of string-stream-test when CONFIG_KUNIT_TEST=m; this
is to avoid having to deal with symbol lookup issues
- changed string-stream-impl.h back to string-stream.h (Brendan)
- added module build support to new list, ext4 tests
Changes since v2:
- moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan)
(patch 1)
- split out non-exported interfaces in try-catch-impl.h (Brendan)
(patch 2)
- added kunit_find_symbol() and KUNIT_INIT_SYMBOL to lookup non-exported
symbols (patches 3, 4)
- removed #ifdef MODULE around module licenses (Randy, Brendan, Andy)
(patch 4)
- replaced kunit_test_suite() with kunit_test_suites() rather than
supporting both (Brendan) (patch 4)
- lookup sysctl_hung_task_timeout_secs as kunit may be built as a module
and the symbol may not be available (patch 5)
Alan Maguire (6):
kunit: move string-stream.h to lib/kunit
kunit: hide unexported try-catch interface in try-catch-impl.h
kunit: allow kunit tests to be loaded as a module
kunit: remove timeout dependence on sysctl_hung_task_timeout_seconds
kunit: allow kunit to be loaded as a module
kunit: update documentation to describe module-based build

[PATCH v6 00/24] mm/gup: track dma-pinned pages: FOLL_PIN
by John Hubbard
Hi,
Christoph Hellwig has a preference to do things a little differently,
for the devmap cleanup in patch 5 ("mm: devmap: refactor 1-based
refcounting for ZONE_DEVICE pages"). That came up in a different
review thread, because the patch is out for review in two locations.
Here's that review thread:
https://lore.kernel.org/r/20191118070826.GB3099@infradead.org
...and I'm hoping that we can defer that request, because otherwise
it derails this series, which is starting to otherwise look like
it could be ready for 5.5.
There is a git repo and branch, for convenience:
git@github.com:johnhubbard/linux.git pin_user_pages_tracking_v6
Changes since v5:
* Fixed the refcounting for huge pages: in most cases, it was
only taking one GUP_PIN_COUNTING_BIAS's worth of refs, when it
should have been taking one GUP_PIN_COUNTING_BIAS for each subpage.
(Much thanks to Jan Kara for spotting that one!)
* Renamed user_page_ref_inc() to try_pin_page(), and added a new
try_pin_compound_head(). This definitely improves readability.
* Factored out some more duplication in the FOLL_PIN and FOLL_GET
cases, in gup.c.
* Fixed up some straggling "get_" --> "pin_" references in the comments.
* Added reviewed-by tags.
Changes since v4:
* Renamed put_user_page*() --> unpin_user_page().
* Removed all pin_longterm_pages*() calls. We will use FOLL_LONGTERM
at the call sites. (FOLL_PIN, however, remains an internal gup flag).
This is very nice: many patches just change three characters now:
get_user_pages --> pin_user_pages. I think we've found the right
balance of wrapper calls and gup flags, for the call sites.
* Updated a lot of documentation and commit logs to match the above
two large changes.
* Changed gup_benchmark tests and run_vmtests, to adapt to one less
use case: there is no pin_longterm_pages() call anymore.
* This includes a new devmap cleanup patch from Dan Williams, along
with a rebased follow-up: patches 4 and 5, already mentioned above.
* Fixed patch 10 ("mm/gup: introduce pin_user_pages*() and FOLL_PIN"),
so as to make pin_user_pages*() calls act as placeholders for the
corresponding get_user_pages*() calls, until a later patch fully
implements the DMA-pinning functionality.
Thanks to Jan Kara for noticing that.
* Fixed the implementation of pin_user_pages_remote().
* Further tweaked patch 2 ("mm/gup: factor out duplicate code from four
routines"), in response to Jan Kara's feedback.
* Dropped a few reviewed-by tags due to changes that invalidated
them.
Changes since v3:
* VFIO fix (patch 8): applied further cleanup: removed a pre-existing,
unnecessary release and reacquire of mmap_sem. Moved the DAX vma
checks from the vfio call site, to gup internals, and added comments
(and commit log) to clarify.
* Due to the above, made a corresponding fix to the
pin_longterm_pages_remote(), which was actually calling the wrong
gup internal function.
* Changed put_user_page() comments, to refer to pin*() APIs, rather than
get_user_pages*() APIs.
* Reverted an accidental whitespace-only change in the IB ODP code.
* Added a few more reviewed-by tags.
Changes since v2:
* Added a patch to convert IB/umem from normal gup, to gup_fast(). This
is also posted separately, in order to hopefully get some runtime
testing.
* Changed the page devmap code to be a little clearer,
thanks to Jerome for that.
* Split out the page devmap changes into a separate patch (and moved
Ira's Signed-off-by to that patch).
* Fixed my bug in IB: ODP code does not require pin_user_pages()
semantics. Therefore, revert the put_user_page() calls to put_page(),
and leave the get_user_pages() call as-is.
* As part of the revert, I am proposing here a change directly
from put_user_pages(), to release_pages(). I'd feel better if
someone agrees that this is the best way. It uses the more
efficient release_pages(), instead of put_page() in a loop,
and keep the change to just a few character on one line,
but OTOH it is not a pure revert.
* Loosened the FOLL_LONGTERM restrictions in the
__get_user_pages_locked() implementation, and used that in order
to fix up a VFIO bug. Thanks to Jason for that idea.
* Note the use of release_pages() in IB: is that OK?
* Added a few more WARN's and clarifying comments nearby.
* Many documentation improvements in various comments.
* Moved the new pin_user_pages.rst from Documentation/vm/ to
Documentation/core-api/ .
* Commit descriptions: added clarifying notes to the three patches
(drm/via, fs/io_uring, net/xdp) that already had put_user_page()
calls in place.
* Collected all pending Reviewed-by and Acked-by tags, from v1 and v2
email threads.
* Lot of churn from v2 --> v3, so it's possible that new bugs
sneaked in.
NOT DONE: separate patchset is required:
* __get_user_pages_locked(): stop compensating for
buggy callers who failed to set FOLL_GET. Instead, assert
that FOLL_GET is set (and fail if it's not).
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-9: refactoring and preparatory cleanup, independent fixes
* Patch 10: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 11-16: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 17: Activate tracking of FOLL_PIN pages.
* Patches 18-20: convert various callers
* Patches: 21-23: gup_benchmark and run_vmtests support
* Patch 24: rename put_user_page*() --> unpin_user_page*()
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH RESEND v17 00/13] open: introduce openat2(2) syscall
by Aleksa Sarai
This patchset is being developed here:
<https://github.com/cyphar/linux/tree/openat2/master>
This is a re-send of
<https://lore.kernel.org/lkml/20191117011713.13032-1-cyphar@cyphar.com/>
but rebased on top of 5.4-rc8 (also my mails got duplicated the first
time I sent v17 -- hopefully that doesn't happen this time).
Patch changelog:
v17:
* Add a path_is_under() check for LOOKUP_IS_SCOPED in complete_walk(), as a
last line of defence to ensure that namei bugs will not break the contract
of LOOKUP_BENEATH or LOOKUP_IN_ROOT.
* Update based on feedback by Al Viro:
* Make nd_jump_link() free the passed path on error, so that callers don't
need to worry about it in the error path.
* Remove needless m_retry and r_retry variables in handle_dots().
* Always return -ECHILD from follow_dotdot_rcu().

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and
possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes
though stale NFS handles).

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the direc-
tory referred to by the file descriptor dirfd (or the current working directory of the
calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then
dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is
resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not con-
tain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see path_resolu-
tion(7) for background information.) The primary use case for these flags
is to allow trusted programs to restrict how untrusted paths (or paths in-
side untrusted directories) are resolved. The full list of resolve flags is
given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as bind mounts are
very widely used by end-users. Setting this flag indiscrimnately for
all uses of openat2() may result in spurious errors on previously-
functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as symbolic links
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on previ-
ously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly open-
ing these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of path-
name) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute sym-
bolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root perma-
nently for a process), RESOLVE_IN_ROOT allows a program to effi-
ciently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are han-
dled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or poten-
tial attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new ex-
tension fields will always be appended, the size will always increase.) This extensibil-
ity design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel sup-
ports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-compatibil-
ity.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all ex-
tensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported ex-
tension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of exten-
sions. However, if a userspace program wishes to determine what extensions the running
kernel supports, they may conduct a binary search on size (to find the largest value which
doesn't produce an error of E2BIG.)

+=================
+
+What is kunit_tool?
+===================
+
+kunit_tool is a script (``tools/testing/kunit/kunit.py``) that aids in building
+the Linux kernel as UML (`User Mode Linux
+<http://user-mode-linux.sourceforge.net/>`_), running KUnit tests, parsing
+the test results and displaying them in a user friendly manner.
+
+What is a kunitconfig?
+======================
+
+It's just a defconfig that kunit_tool looks for in the base directory.
+kunit_tool uses it to generate a .config as you might expect. In addition, it
+verifies that the generated .config contains the CONFIG options in the
+kunitconfig; the reason it does this is so that it is easy to be sure that a
+CONFIG that enables a test actually ends up in the .config.
+
+How do I use kunit_tool?
+========================
+
+If a kunitconfig is present at the root directory, all you have to do is:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run
+
+However, you most likely want to use it with the following options:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all`
+
+- ``--timeout`` sets a maximum amount of time to allow tests to run.
+- ``--jobs`` sets the number of threads to use to build the kernel.
+
+If you just want to use the defconfig that ships with the kernel, you can
+append the ``--defconfig`` flag as well:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all` --defconfig
+
+.. note::
+ This command is particularly helpful for getting started because it
+ just works. No kunitconfig needs to be present.
+
+For a list of all the flags supported by kunit_tool, you can run:

[PATCH v5 00/24] mm/gup: track dma-pinned pages: FOLL_PIN
by John Hubbard
Hi,
Please note that two of these patches are also out for review
separately, and may go in earlier than this series. This series
requires those, so to ease review and testing, they are also
included here: patches 4 and 5, the devmap cleanups.
There is a git repo and branch, for convenience:
git@github.com:johnhubbard/linux.git pin_user_pages_tracking_v5
Despite the large number of changes, it does feel like the review
comments are converging, btw.
Changes since v4:
* Renamed put_user_page*() --> unpin_user_page().
* Removed all pin_longterm_pages*() calls. We will use FOLL_LONGTERM
at the call sites. (FOLL_PIN, however, remains an internal gup flag).
This is very nice: many patches just change three characters now:
get_user_pages --> pin_user_pages. I think we've found the right
balance of wrapper calls and gup flags, for the call sites.
* Updated a lot of documentation and commit logs to match the above
two large changes.
* Changed gup_benchmark tests and run_vmtests, to adapt to one less
use case: there is no pin_longterm_pages() call anymore.
* This includes a new devmap cleanup patch from Dan Williams, along
with a rebased follow-up: patches 4 and 5, already mentioned above.
* Fixed patch 10 ("mm/gup: introduce pin_user_pages*() and FOLL_PIN"),
so as to make pin_user_pages*() calls act as placeholders for the
corresponding get_user_pages*() calls, until a later patch fully
implements the DMA-pinning functionality.
Thanks to Jan Kara for noticing that.
* Fixed the implementation of pin_user_pages_remote().
* Further tweaked patch 2 ("mm/gup: factor out duplicate code from four
routines"), in response to Jan Kara's feedback.
* Dropped a few reviewed-by tags due to changes that invalidated
them.
Changes since v3:
* VFIO fix (patch 8): applied further cleanup: removed a pre-existing,
unnecessary release and reacquire of mmap_sem. Moved the DAX vma
checks from the vfio call site, to gup internals, and added comments
(and commit log) to clarify.
* Due to the above, made a corresponding fix to the
pin_longterm_pages_remote(), which was actually calling the wrong
gup internal function.
* Changed put_user_page() comments, to refer to pin*() APIs, rather than
get_user_pages*() APIs.
* Reverted an accidental whitespace-only change in the IB ODP code.
* Added a few more reviewed-by tags.
Changes since v2:
* Added a patch to convert IB/umem from normal gup, to gup_fast(). This
is also posted separately, in order to hopefully get some runtime
testing.
* Changed the page devmap code to be a little clearer,
thanks to Jerome for that.
* Split out the page devmap changes into a separate patch (and moved
Ira's Signed-off-by to that patch).
* Fixed my bug in IB: ODP code does not require pin_user_pages()
semantics. Therefore, revert the put_user_page() calls to put_page(),
and leave the get_user_pages() call as-is.
* As part of the revert, I am proposing here a change directly
from put_user_pages(), to release_pages(). I'd feel better if
someone agrees that this is the best way. It uses the more
efficient release_pages(), instead of put_page() in a loop,
and keep the change to just a few character on one line,
but OTOH it is not a pure revert.
* Loosened the FOLL_LONGTERM restrictions in the
__get_user_pages_locked() implementation, and used that in order
to fix up a VFIO bug. Thanks to Jason for that idea.
* Note the use of release_pages() in IB: is that OK?
* Added a few more WARN's and clarifying comments nearby.
* Many documentation improvements in various comments.
* Moved the new pin_user_pages.rst from Documentation/vm/ to
Documentation/core-api/ .
* Commit descriptions: added clarifying notes to the three patches
(drm/via, fs/io_uring, net/xdp) that already had put_user_page()
calls in place.
* Collected all pending Reviewed-by and Acked-by tags, from v1 and v2
email threads.
* Lot of churn from v2 --> v3, so it's possible that new bugs
sneaked in.
NOT DONE: separate patchset is required:
* __get_user_pages_locked(): stop compensating for
buggy callers who failed to set FOLL_GET. Instead, assert
that FOLL_GET is set (and fail if it's not).
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-9: refactoring and preparatory cleanup, independent fixes
* Patch 10: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 11-16: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 17: Activate tracking of FOLL_PIN pages.
* Patches 18-20: convert various callers
* Patches: 21-23: gup_benchmark and run_vmtests support
* Patch 24: rename put_user_page*() --> unpin_user_page*()
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH v4 0/2] HMM tests and minor fixes
by Ralph Campbell
These changes are based on Jason's rdma/hmm branch (5.4.0-rc5).
Patch 1 was previously posted here [1] but was dropped from that orginal
series. Hopefully, the tests will reduce concerns about edge conditions.
I'm sure more tests could be usefully added but I thought this was a good
starting point.
Changes since v3:
patch 1:
Unchanged except rebased on Jason's latest hmm (bbe3329e354d3ab5dc18).
patch 2:
Is now part of Jason's tree.
patch 3 (now 2):
Major changes to incorporate Jason's review feedback.
* drivers/char/hmm_dmirror.c driver moved to lib/test_hmm.c
* XArray used instead of "page tables".
* platform device driver removed.
* remove redundant copyright.
Changes since v2:
patch 1:
Removed hmm_range_needs_fault() and just use hmm_range_need_fault().
Updated the change log to include that it fixes a bug where
hmm_range_fault() incorrectly returned an error when no fault is requested.
patch 2:
Removed the confusing change log wording about DMA.
Changed hmm_range_fault() to return the PFN of the zero page like any other
page.
patch 3:
Adjusted the test code to match the new zero page behavior.
Changes since v1:
Rebased to Jason's rdma/hmm branch (5.4.0-rc1).
Cleaned up locking for the test driver's page tables.
Incorporated Christoph Hellwig's comments.

[PATCH v17 00/13] open: introduce openat2(2) syscall
by Aleksa Sarai
This patchset is being developed here:
<https://github.com/cyphar/linux/tree/openat2/master>
Patch changelog:
v17:
* Add a path_is_under() check for LOOKUP_IS_SCOPED in complete_walk(), as a
last line of defence to ensure that namei bugs will not break the contract
of LOOKUP_BENEATH or LOOKUP_IN_ROOT.
* Update based on feedback by Al Viro:
* Make nd_jump_link() free the passed path on error, so that callers don't
need to worry about it in the error path.
* Remove needless m_retry and r_retry variables in handle_dots().
* Always return -ECHILD from follow_dotdot_rcu().

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and
possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes
though stale NFS handles).

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the direc-
tory referred to by the file descriptor dirfd (or the current working directory of the
calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then
dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is
resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not con-
tain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see path_resolu-
tion(7) for background information.) The primary use case for these flags
is to allow trusted programs to restrict how untrusted paths (or paths in-
side untrusted directories) are resolved. The full list of resolve flags is
given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as bind mounts are
very widely used by end-users. Setting this flag indiscrimnately for
all uses of openat2() may result in spurious errors on previously-
functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as symbolic links
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on previ-
ously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly open-
ing these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of path-
name) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute sym-
bolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root perma-
nently for a process), RESOLVE_IN_ROOT allows a program to effi-
ciently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are han-
dled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or poten-
tial attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new ex-
tension fields will always be appended, the size will always increase.) This extensibil-
ity design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel sup-
ports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-compatibil-
ity.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all ex-
tensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported ex-
tension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of exten-
sions. However, if a userspace program wishes to determine what extensions the running
kernel supports, they may conduct a binary search on size (to find the largest value which
doesn't produce an error of E2BIG.)

[PATCH v16 00/12] open: introduce openat2(2) syscall
by Aleksa Sarai
This patchset is being developed here:
<https://github.com/cyphar/linux/tree/openat2/master>
Patch changelog:
v16:
* Update based on review by Al Viro:
* Handle magic-link related errors from with nd_jump_link() and drop
LOOKUP_MAGICLINK_JUMPED.
* Drop the slash-skipping logic for LOOKUP_IN_ROOT since it's not actually
necessary (link_path_walk() already does it, and it's possible that doing
it slightly breaks downstream code).
* Update outdated open_how documentation to match new semantics.
* Update commit message to further explain why -EAGAIN is preferable for
path_is_under() when checking whether ".." is safe.
* Split out the set_root() and nd_jump_root() errors from the
LOOKUP_BENEATH patch.
* Expand path-lookup documentation changes to describe all new LOOKUP flags.
* Cleanup the signature of ns_get_path() such that it returns an int
(previously it returned a void * -- even though the only two
possible return values were ERR_PTR or NULL).

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and
possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes
though stale NFS handles).

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the direc-
tory referred to by the file descriptor dirfd (or the current working directory of the
calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then
dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is
resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not con-
tain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see path_resolu-
tion(7) for background information.) The primary use case for these flags
is to allow trusted programs to restrict how untrusted paths (or paths in-
side untrusted directories) are resolved. The full list of resolve flags is
given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as bind mounts are
very widely used by end-users. Setting this flag indiscrimnately for
all uses of openat2() may result in spurious errors on previously-
functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as symbolic links
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on previ-
ously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly open-
ing these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of path-
name) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute sym-
bolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root perma-
nently for a process), RESOLVE_IN_ROOT allows a program to effi-
ciently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are han-
dled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or poten-
tial attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new ex-
tension fields will always be appended, the size will always increase.) This extensibil-
ity design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel sup-
ports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-compatibil-
ity.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all ex-
tensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported ex-
tension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of exten-
sions. However, if a userspace program wishes to determine what extensions the running
kernel supports, they may conduct a binary search on size (to find the largest value which
doesn't produce an error of E2BIG.)

[PATCH AUTOSEL 4.14 092/150] selftests/powerpc/cache_shape: Fix out-of-tree build
by Sasha Levin
From: Michael Ellerman <mpe(a)ellerman.id.au>
[ Upstream commit 69f8117f17b332a68cd8f4bf8c2d0d3d5b84efc5 ]
Use TEST_GEN_PROGS and don't redefine all, this makes the out-of-tree
build work. We need to move the extra dependencies below the include
of lib.mk, because it adds the $(OUTPUT) prefix if it's defined.
We can also drop the clean rule, lib.mk does it for us.

From: Joel Stanley <joel(a)jms.id.au>
[ Upstream commit 27825349d7b238533a47e3d98b8bb0efd886b752 ]
We should use TEST_GEN_PROGS, not TEST_PROGS. That tells the selftests

When /dev/watchdog open fails, watchdog exits with "watchdog not enabled"
message. This is incorrect when open fails due to insufficient privilege.
Fix message to clearly state the reason when open fails with EACCESS when
a non-root user runs it.

[PATCH AUTOSEL 4.19 117/237] selftests: watchdog: fix message when /dev/watchdog open fails
by Sasha Levin
From: "Shuah Khan (Samsung OSG)" <shuah(a)kernel.org>
[ Upstream commit 9a244229a4b850b11952a0df79607c69b18fd8df ]
When /dev/watchdog open fails, watchdog exits with "watchdog not enabled"
message. This is incorrect when open fails due to insufficient privilege.
Fix message to clearly state the reason when open fails with EACCESS when
a non-root user runs it.

The return value for each test in test_libbpf.sh is compared with
if (( $? == 0 )) ; then ...
This works well with bash, but not with dash, that /bin/sh is aliased to
on some systems (such as Ubuntu).
Let's replace this comparison by something that works on both shells.

+=================
+kunit_tool How-To
+=================
+
+What is kunit_tool?
+===================
+
+kunit_tool is a script (``tools/testing/kunit/kunit.py``) that aids in building
+the Linux kernel as UML (`User Mode Linux
+<http://user-mode-linux.sourceforge.net/>`_), running KUnit tests, parsing
+the test results and displaying them in a user friendly manner.
+
+What is a kunitconfig?
+======================
+
+It's just a defconfig that kunit_tool looks for in the base directory.
+kunit_tool uses it to generate a .config as you might expect. In addition, it
+verifies that the generated .config contains the CONFIG options in the
+kunitconfig; the reason it does this is so that it is easy to be sure that a
+CONFIG that enables a test actually ends up in the .config.
+
+How do I use kunit_tool?
+=================================
+
+If a kunitconfig is present at the root directory, all you have to do is:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run
+
+However, you most likely want to use it with the following options:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all`
+
+- ``--timeout`` sets a maximum amount of time to allow tests to run.
+- ``--jobs`` sets the number of threads to use to build the kernel.
+
+If you just want to use the defconfig that ships with the kernel, you can
+append the ``--defconfig`` flag as well:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all` --defconfig
+
+.. note::
+ This command is particularly helpful for getting started because it
+ just works. No kunitconfig needs to be present.
+
+For a list of all the flags supported by kunit_tool, you can run:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --help

[PATCH v4] selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)
by Ilya Leoshkevich
Currently the following command produces an error message:
linux# make kselftest TARGETS=bpf O=/mnt/linux-build
# selftests: bpf: test_libbpf.sh
# ./test_libbpf.sh: line 23: ./test_libbpf_open: No such file or directory
# test_libbpf: failed at file test_l4lb.o
# selftests: test_libbpf [FAILED]
The error message might not affect make return code, therefore one might
need to grep make output in order to detect it.
The current logic prepends $(OUTPUT) only to the first member of
$(TEST_PROGS). After that, run_one() does
cd `dirname $TEST`
For all tests except the first one, `dirname $TEST` is ., which means
they cannot access the files generated in $(OUTPUT).
Fix by using $(addprefix) to prepend $(OUTPUT)/ to each member of
$(TEST_PROGS).
Fixes: 1a940687e424 ("selftests: lib.mk: copy test scripts and test files for make O=dir run")
Signed-off-by: Ilya Leoshkevich <iii(a)linux.ibm.com>
---
v1->v2:
- Append / to $(OUTPUT).
- Use $(addprefix) instead of $(foreach).
v2->v3:
- Split the patch in two.
- Improve the commit message.
v3->v4:
- Drop the first patch.
- Add a note regarding make return code to the commit message.

[PATCH linux-kselftest/test v1] Documentation: kunit: add documentation for kunit_tool
by Brendan Higgins
Add documentation for the Python script used to build, run, and collect
results from the kernel known as kunit_tool. kunit_tool
(tools/testing/kunit/kunit.py) was already added in previous commits.

+=================
+kunit_tool How-To
+=================
+
+What is kunit_tool?
+===================
+
+kunit_tool is a set of scripts that aid in building the Linux kernel as UML
+(`User Mode Linux <http://user-mode-linux.sourceforge.net/old/>`_), running
+KUnit tests, parsing the test results and displaying them in a user friendly
+manner.
+
+What is a kunitconfig?
+======================
+
+It's just a defconfig that kunit_tool looks for in the base directory.
+kunit_tool uses it to generate a .config as you might expect. In addition, it
+verifies that the generated .config contains the CONFIG options in the
+kunitconfig; the reason it does this is so that it is easy to be sure that a
+CONFIG that enables a test actually ends up in the .config.
+
+How do I use kunit_tool?
+=================================
+
+If a kunitconfig is present at the root directory, all you have to do is:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run
+
+However, you most likely want to use it with the following options:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=8
+
+- ``--timeout`` sets a maximum amount of time to allow tests to run.
+- ``--jobs`` sets the number of threads to use to build the kernel.
+
+If you just want to use the defconfig that ships with the kernel, you can
+append the ``--defconfig`` flag as well:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=8 --defconfig
+
+.. note::
+ This command is particularly helpful for getting started because it
+ just works. No kunitconfig needs to be present.
+
+For a list of all the flags supported by kunit_tool, you can run:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --help

Sorry for the spam. I accidentally CC'ed the doc list instead of the
kselftest list in my previous email.

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and
possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes
though stale NFS handles).

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the direc-
tory referred to by the file descriptor dirfd (or the current working directory of the
calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then
dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is
resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not con-
tain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see path_resolu-
tion(7) for background information.) The primary use case for these flags
is to allow trusted programs to restrict how untrusted paths (or paths in-
side untrusted directories) are resolved. The full list of resolve flags is
given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as bind mounts are
very widely used by end-users. Setting this flag indiscrimnately for
all uses of openat2() may result in spurious errors on previously-
functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as symbolic links
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on previ-
ously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly open-
ing these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of path-
name) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute sym-
bolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root perma-
nently for a process), RESOLVE_IN_ROOT allows a program to effi-
ciently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are han-
dled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or poten-
tial attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new ex-
tension fields will always be appended, the size will always increase.) This extensibil-
ity design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel sup-
ports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-compatibil-
ity.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all ex-
tensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported ex-
tension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of exten-
sions. However, if a userspace program wishes to determine what extensions the running
kernel supports, they may conduct a binary search on size (to find the largest value which
doesn't produce an error of E2BIG.)

[PATCH v4 00/23] mm/gup: track dma-pinned pages: FOLL_PIN, FOLL_LONGTERM
by John Hubbard
OK, here we go. Any VFIO and Infiniband runtime testing from anyone, is
especially welcome here.
Changes since v3:
* VFIO fix (patch 8): applied further cleanup: removed a pre-existing,
unnecessary release and reacquire of mmap_sem. Moved the DAX vma
checks from the vfio call site, to gup internals, and added comments
(and commit log) to clarify.
* Due to the above, made a corresponding fix to the
pin_longterm_pages_remote(), which was actually calling the wrong
gup internal function.
* Changed put_user_page() comments, to refer to pin*() APIs, rather than
get_user_pages*() APIs.
* Reverted an accidental whitespace-only change in the IB ODP code.
* Added a few more reviewed-by tags.
Changes since v2:
* Added a patch to convert IB/umem from normal gup, to gup_fast(). This
is also posted separately, in order to hopefully get some runtime
testing.
* Changed the page devmap code to be a little clearer,
thanks to Jerome for that.
* Split out the page devmap changes into a separate patch (and moved
Ira's Signed-off-by to that patch).
* Fixed my bug in IB: ODP code does not require pin_user_pages()
semantics. Therefore, revert the put_user_page() calls to put_page(),
and leave the get_user_pages() call as-is.
* As part of the revert, I am proposing here a change directly
from put_user_pages(), to release_pages(). I'd feel better if
someone agrees that this is the best way. It uses the more
efficient release_pages(), instead of put_page() in a loop,
and keep the change to just a few character on one line,
but OTOH it is not a pure revert.
* Loosened the FOLL_LONGTERM restrictions in the
__get_user_pages_locked() implementation, and used that in order
to fix up a VFIO bug. Thanks to Jason for that idea.
* Note the use of release_pages() in IB: is that OK?
* Added a few more WARN's and clarifying comments nearby.
* Many documentation improvements in various comments.
* Moved the new pin_user_pages.rst from Documentation/vm/ to
Documentation/core-api/ .
* Commit descriptions: added clarifying notes to the three patches
(drm/via, fs/io_uring, net/xdp) that already had put_user_page()
calls in place.
* Collected all pending Reviewed-by and Acked-by tags, from v1 and v2
email threads.
* Lot of churn from v2 --> v3, so it's possible that new bugs
sneaked in.
NOT DONE: separate patchset is required:
* __get_user_pages_locked(): stop compensating for
buggy callers who failed to set FOLL_GET. Instead, assert
that FOLL_GET is set (and fail if it's not).
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-8: refactoring and preparatory cleanup, independent fixes
* Patch 9: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 10-15: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 16: Activate tracking of FOLL_PIN pages.
* Patches 17-19: convert FOLL_LONGTERM callers
* Patches: 20-22: gup_benchmark and run_vmtests support
* Patch 23: enforce FOLL_LONGTERM as a gup-internal (only) flag
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

selftests/bpf: make *** tools/bpf/bpftool No such file or directory. Stop.
by Naresh Kamboju
selftests bpf test_bpftool_build.sh failed on arm32 beagleboard x15
device with below error.
Can this be skipped with minimal verbose on console ?
In our setup, we build kselftests on server machine and copies onto
target device and run tests by using run_kselftest.sh script file.

[PATCH v3 00/23] mm/gup: track dma-pinned pages: FOLL_PIN, FOLL_LONGTERM
by John Hubbard
Hi,
The cover letter is long, so the more important stuff is first:
* Jason, if you or someone could look at the the VFIO cleanup (patch 8)
and conversion to FOLL_PIN (patch 18), to make sure it's use of
remote and longterm gup matches what we discussed during the review
of v2, I'd appreciate it.
* Also for Jason and IB: as noted below, in patch 11, I am (too?) boldly
converting from put_user_pages() to release_pages().
* Jerome, I am going to take a look at doing your FOLL_GET change idea
(some callers should set FOLL_GET) separately, because it blew up "a
little bit" in my face. It's definitely a separate--tiny, but risky--project.
It also looks more reasonable when applied on top of this series here
(and it conflicts a lot), so I'm going to send it as a follow-up.
Changes since v2:
* Added a patch to convert IB/umem from normal gup, to gup_fast(). This
is also posted separately, in order to hopefully get some runtime
testing.
* Changed the page devmap code to be a little clearer,
thanks to Jerome for that.
* Split out the page devmap changes into a separate patch (and moved
Ira's Signed-off-by to that patch).
* Fixed my bug in IB: ODP code does not require pin_user_pages()
semantics. Therefore, revert the put_user_page() calls to put_page(),
and leave the get_user_pages() call as-is.
* As part of the revert, I am proposing here a change directly
from put_user_pages(), to release_pages(). I'd feel better if
someone agrees that this is the best way. It uses the more
efficient release_pages(), instead of put_page() in a loop,
and keep the change to just a few character on one line,
but OTOH it is not a pure revert.
* Loosened the FOLL_LONGTERM restrictions in the
__get_user_pages_locked() implementation, and used that in order
to fix up a VFIO bug. Thanks to Jason for that idea.
* Note the use of release_pages() in IB: is that OK?
* Added a few more WARN's and clarifying comments nearby.
* Many documentation improvements in various comments.
* Moved the new pin_user_pages.rst from Documentation/vm/ to
Documentation/core-api/ .
* Commit descriptions: added clarifying notes to the three patches
(drm/via, fs/io_uring, net/xdp) that already had put_user_page()
calls in place.
* Collected all pending Reviewed-by and Acked-by tags, from v1 and v2
email threads.
* Lot of churn from v2 --> v3, so it's possible that new bugs
sneaked in.
NOT DONE: separate patchset is required:
* __get_user_pages_locked(): stop compensating for
buggy callers who failed to set FOLL_GET. Instead, assert
that FOLL_GET is set (and fail if it's not).
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-8: refactoring and preparatory cleanup, independent fixes
* Patch 9: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 10-15: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 16: Activate tracking of FOLL_PIN pages.
* Patches 17-19: convert FOLL_LONGTERM callers
* Patches: 20-22: gup_benchmark and run_vmtests support
* Patch 23: enforce FOLL_LONGTERM as a gup-internal (only) flag
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH v4 2/2] pidfd: add tests for NSpid info in fdinfo
by Christian Kellner
From: Christian Kellner <christian(a)kellner.me>
Add a test that checks that if pid namespaces are configured the fdinfo
file of a pidfd contains an NSpid: entry containing the process id in
the current and additionally all nested namespaces. In the case that
a pidfd is from a pid namespace not in the same namespace hierarchy as
the process accessing the fdinfo file, ensure the 'NSpid' shows 0 for
that pidfd, analogous to the 'Pid' entry.
Signed-off-by: Christian Kellner <christian(a)kellner.me>
---
Changes in v4:
- Rework to test include a the situation where the fdinfo for a pidfd
of a process in a sibling pid namespace is being read and ensure
the NSpid field only contains one entry, being 0.

[PATCH AUTOSEL 4.19 193/209] selftests: forwarding: Have lldpad_app_wait_set() wait for unknown, too
by Sasha Levin
From: Petr Machata <petrm(a)mellanox.com>
[ Upstream commit 372809055f6c830ff978564e09f58bcb9e9b937c ]
Immediately after mlxsw module is probed and lldpad started, added APP
entries are briefly in "unknown" state before becoming "pending". That's
the state that lldpad_app_wait_set() typically sees, and since there are
no pending entries at that time, it bails out. However the entries have
not been pushed to the kernel yet at that point, and thus the test case
fails.
Fix by waiting for both unknown and pending entries to disappear before
proceeding.

[PATCH AUTOSEL 4.19 124/209] tc-testing: fix build of eBPF programs
by Sasha Levin
From: Davide Caratti <dcaratti(a)redhat.com>
[ Upstream commit cf5eafbfa586d030f9321cee516b91d089e38280 ]
rely on uAPI headers in the current kernel tree, rather than requiring the
correct version installed on the test system. While at it, group all
sections in a single binary and test the 'section' parameter.

[PATCH AUTOSEL 4.19 033/209] selftests/tls: Fix recv(MSG_PEEK) & splice() test cases
by Sasha Levin
From: Vakul Garg <vakul.garg(a)nxp.com>
[ Upstream commit 0ed3015c9964dab7a1693b3e40650f329c16691e ]
TLS test cases splice_from_pipe, send_and_splice &
recv_peek_multiple_records expect to receive a given nummber of bytes
and then compare them against the number of bytes which were sent.
Therefore, system call recv() must not return before receiving the
requested number of bytes, otherwise the subsequent memcmp() fails.
This patch passes MSG_WAITALL flag to recv() so that it does not return
prematurely before requested number of bytes are copied to receive
buffer.

That looks ok. Something to maybe push down into the core in a future
cleanup, but not something that needs to be done now.

[PATCH] kselftests: cgroup: Avoid the reuse of fd after it is deallocated
by Hewenliang
It is necessary to set fd to -1 when inotify_add_watch() fails in
cg_prepare_for_wait. Otherwise the fd which has been closed in
cg_prepare_for_wait may be misused in other functions such as
cg_enter_and_wait_for_frozen and cg_freeze_wait.
Fixes: 5313bfe425c8 ("selftests: cgroup: add freezer controller self-tests")

[PATCH v4] selftests: add tests for clone3()
by Adrian Reber
This adds tests for clone3() with different values and sizes
of struct clone_args.
This selftest was initially part of of the clone3() with PID selftest.
After that patch was almost merged Eugene sent out a couple of patches
to fix problems with these test.
This commit now only contains the clone3() selftest after the LPC
decision to rework clone3() with PID to allow setting the PID in
multiple PID namespaces including all of Eugene's patches.

v2:
- Applied Christian's suggestions
- Skip root-only tests when running as non-root
v3:
- Removed unnecessary test case (everything set to 1)
- Correctly handle children without SIGCHLD
v4:
- Small cosmetic fixes
- Added two more tests with different sizes

[PATCH] selftests: Move kselftest_module.sh into kselftest/
by Kees Cook
The kselftest_module.sh file was not being installed by the Makefile
"install" target, rendering the lib/*.sh tests nonfunction. This fixes
that and takes the opportunity to move it into the kselftest/ subdirectory
which is where the kselftest infrastructure bits are collecting.

[PATCH v2 00/18] mm/gup: track dma-pinned pages: FOLL_PIN, FOLL_LONGTERM
by John Hubbard
Hi,
Changes since v1:
* Changed the function signature of __huge_pt_done() from int to void.
* Renamed __remove_refs_from_head() to put_compound_head().
* Improved the comment documentation in mm.h and gup.c
* Merged Documentation/vm/pin_user_pages.rst into the "introduce
FOLL_PIN" patch.
* Fixed Documentation/vm/pin_user_pages.rst:
* Fixed up a TODO about DAX.
* 31, not 32 bits total are available for counting
* Deleted some stale comments from the commit description of the
VFIO patch.
* Added Reviewed-by tags from Ira Weiny and Jens Axboe, and Acked-by
from Björn Töpel.
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-4: refactoring and preparatory cleanup, independent fixes
(Patch 4: V4L2-core bug fix (can be separately applied))
* Patch 5: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 6-11: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 12: Activate tracking of FOLL_PIN pages.
* Patches 13-15: convert FOLL_LONGTERM callers
* Patches: 16-17: gup_benchmark and run_vmtests support
* Patch 18: enforce FOLL_LONGTERM as a gup-internal (only) flag
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH v3 linux-kselftest-test 0/6] kunit: support building core/tests as modules
by Alan Maguire
The current kunit execution model is to provide base kunit functionality
and tests built-in to the kernel. The aim of this series is to allow
building kunit itself and tests as modules. This in turn allows a
simple form of selective execution; load the module you wish to test.
In doing so, kunit itself (if also built as a module) will be loaded as
an implicit dependency.
Because this requires a core API modification - if a module delivers
multiple suites, they must be declared with the kunit_test_suites()
macro - we're proposing this patch set as a candidate to be applied to the
test tree before too many kunit consumers appear. We attempt to deal
with existing consumers in patch 4.
Changes since v2:
- moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan)
(patch 1)
- split out non-exported interfaces in try-catch-impl.h (Brendan)
(patch 2)
- added kunit_find_symbol() and KUNIT_INIT_*SYMBOL to lookup non-exported
symbols. KUNIT_INIT_*SYMBOL() is defined so that a mismatch between
local symbol definition and definition of symbol in target will trigger
a compilation error when the object is compiled built-in (Brendan)
(patches 3, 4)
- removed #ifdef MODULE around module licenses (Randy, Brendan, Andy)
(patch 4)
- replaced kunit_test_suite() with kunit_test_suites() rather than
supporting both (Brendan) (patch 4)
- lookup sysctl_hung_task_timeout_secs as kunit may be built as a module
and the symbol may not be available (patch 5)
- fixed whitespace issues in doc (patch 6)
Alan Maguire (6):
kunit: move string-stream.h to lib/kunit/string-stream-impl.h
kunit: hide unexported try-catch interface in try-catch-impl.h
kunit: add kunit_find_symbol() function for symbol lookup
kunit: allow kunit tests to be loaded as a module
kunit: allow kunit to be loaded as a module
kunit: update documentation to describe module-based build

[PATCH v3] selftests: add tests for clone3()
by Adrian Reber
This adds tests for clone3() with different values and sizes
of struct clone_args.
This selftest was initially part of of the clone3() with PID selftest.
After that patch was almost merged Eugene sent out a couple of patches
to fix problems with these test.
This commit now only contains the clone3() selftest after the LPC
decision to rework clone3() with PID to allow setting the PID in
multiple PID namespaces including all of Eugene's patches.

v2:
- Applied Christian's suggestions
- Skip root-only tests when running as non-root
v3:
- Removed unnecessary test case (everything set to 1)
- Correctly handle children without SIGCHLD

[PATCH 1/2] selftests: bpf: test_lwt_ip_encap: add missing object file to TEST_FILES
by Anders Roxell
When installing kselftests to its own directory and running the
test_lwt_ip_encap.sh it will complain that test_lwt_ip_encap.o can't be
find.
$ ./test_lwt_ip_encap.sh
starting egress IPv4 encap test
Error opening object test_lwt_ip_encap.o: No such file or directory
Object hashing failed!
Cannot initialize ELF context!
Failed to parse eBPF program: Invalid argument
Rework to add test_lwt_ip_encap.o to TEST_FILES so the object file gets
installed when installing kselftest.

[PATCH AUTOSEL 4.19 027/191] selftests/powerpc: Do not fail with reschedule
by Sasha Levin
From: Breno Leitao <leitao(a)debian.org>
[ Upstream commit 44d947eff19d64384efc06069509db7a0a1103b0 ]
There are cases where the test is not expecting to have the transaction
aborted, but, the test process might have been rescheduled, either in the
OS level or by KVM (if it is running on a KVM guest machine). The process
reschedule will cause a treclaim/recheckpoint which will cause the
transaction to doom, aborting the transaction as soon as the process is
rescheduled back to the CPU. This might cause the test to fail, but this is
not a failure in essence.
If that is the case, TEXASR[FC] is indicated with either
TM_CAUSE_RESCHEDULE or TM_CAUSE_KVM_RESCHEDULE for KVM interruptions.
In this scenario, ignore these two failures and avoid the whole test to
return failure.

F_SEAL_FUTURE_WRITE has unexpected behavior when used with MAP_PRIVATE:
A private mapping created after the memfd file that gets sealed with
F_SEAL_FUTURE_WRITE loses the copy-on-write at fork behavior, meaning
children and parent share the same memory, even though the mapping is
private.
The reason for this is due to the code below:
static int shmem_mmap(struct file *file, struct vm_area_struct *vma)
{
struct shmem_inode_info *info = SHMEM_I(file_inode(file));
if (info->seals & F_SEAL_FUTURE_WRITE) {
/*
* New PROT_WRITE and MAP_SHARED mmaps are not allowed when
* "future write" seal active.
*/
if ((vma->vm_flags & VM_SHARED) && (vma->vm_flags & VM_WRITE))
return -EPERM;
/*
* Since the F_SEAL_FUTURE_WRITE seals allow for a MAP_SHARED
* read-only mapping, take care to not allow mprotect to revert
* protections.
*/
vma->vm_flags &= ~(VM_MAYWRITE);
}
...
}
And for the mm to know if a mapping is copy-on-write:
static inline bool is_cow_mapping(vm_flags_t flags)
{
return (flags & (VM_SHARED | VM_MAYWRITE)) == VM_MAYWRITE;
}
The patch fixes the issue by making the mprotect revert protection
happen only for shared mappings. For private mappings, using mprotect
will have no effect on the seal behavior.

[PATCH v10 00/12] Add arm64/signal initial kselftest support
by Cristian Marussi
Hi
this patchset aims to add the initial arch-specific arm64 support to
kselftest starting with signals-related test-cases.
This series is based on v5.4-rc4.
A common internal test-case layout is proposed for signal tests and it is
wired-up to the toplevel kselftest Makefile, so that it should be possible
at the end to run it on an arm64 target in the usual way with KSFT.
~/linux# make TARGETS=arm64 kselftest
New KSFT arm64 testcases live inside tools/testing/selftests/arm64 grouped
by family inside subdirectories: arm64/signal is the first family proposed
with this series.
This series converts also to this subdirectory scheme the pre-existing
KSFT arm64 tags tests (already merged in v5.3), moving them into their own
arm64/tags subdirectory.
Thanks
Cristian
Notes:
-----
- further details in the included READMEs
- more tests still to be written (current strategy is going through the
related Kernel signal-handling code and write a test for each possible
and sensible code-path)
A few ideas for more TODO testcases:
- mangle_pstate_invalid_ssbs_regs: mess with SSBS bits on every
possible configured behavior
- fake_sigreturn_unmapped_sp: SP into unmapped addrs
- fake_sigreturn_kernelspace_sp: SP into kernel addrs
- fake_sigreturn_sve_bad_extra_context: SVE extra context badly formed
- fake_sigreturn_misaligned_sp_4: misaligned SP by 4
(i.e., __alignof__(struct _aarch64_ctx))
- fake_sigreturn_misaligned_sp_8: misaligned SP by 8
(i.e., sizeof(struct _aarch64_ctx))
- fake_sigreturn_bad_size_non_aligned: a size that doesn't overflow
__reserved[], but is not a multiple of 16
- fake_sigreturn_bad_size_tiny: a size that is less than 16
- fake_sigreturn_bad_size_overflow_tiny: a size that does overflow
__reserved[], but by less than 16 bytes?
- mangle_sve_invalid_extra_context: SVE extra_context invalid
- SVE signal testcases and special handling will be part of an additional
patch still to be released
- KSFT arm64 tags test patch
https://lore.kernel.org/linux-arm-kernel/c1e6aad230658bc175b42d92daeff2e300…
is relocated into its own directory under tools/testing/selftests/arm64/tags
Changes:
--------
v9 --> v10:
- rebased on v5.4-rc4
- removed some test_init stale code related to PAN/UAO
(not used nor needed and wrong)
v8-->v9:
- fixed a couple of misplaced .gitignore
v7-->v8:
- removed SSBS test case
- split remnants of SSBS patch (v7 05/11), containing some helpers,
into two distinct patches
v6-->v7:
- rebased on v5.4-rc2
- renamed SUBTARGETS arm64/ toplevel Makefile ENV to ARM64_SUBTARGETS
- fixed fake_sigreturn alignment routines (off by one)
- fixed SSBS test: avoid using MRS/MSR as whole and SKIP when SSBS not
supported
- reporting KSFT_SKIP when needed (usually if test_init(0 fails)
- using ID_AA64PFR1_EL1.SSBS to check SSBS support instead of HWCAP_SSBS
v5-->v6:
- added arm64 toplevel Makefile SUBTARGETS env var to be able to selectively
build only some arm64/ tests subdirectories
- removed unneed toplevel Makefile exports and fixed Copyright
- better checks for supported features and features names helpers
- converted some run-time critical assert() to abort() to avoid
issues when -NDEBUG is set
- default_handler() signal handler refactored and split
- using SIGTRAP for get_current_context()
- use volatile where proper
- refactor and relocate test_init() invocation
- review usage of MRS SSBS instructions depending on HW_SSBS

- avoiding timeout test failures wherever possible (fail immediately
if possible)
v4-->v5:
- rebased on arm64/for-next-core merging 01/11 with KSFT tags tests:
commit 9ce1263033cd ("selftests, arm64: add a selftest for passing tagged pointers to kernel")
- moved .gitignore up on elevel
- moved kernel header search mechanism into KSFT arm64 toplevel Makefile
so that it can be used easily also by each arm64 KSFT subsystem inside
subdirs of arm64
v3-->v4:
- rebased on v5.3-rc6
- added test descriptions

- removed some still broken/immature tests:
+ fake_sigreturn_misaligned
+ fake_sigreturn_overflow_reserved
+ mangle_pc_invalid
+ mangle_sp_misaligned
- fixed some other testcases:
+ mangle_pstate_ssbs_regs: better checks of SSBS bit when feature unsupported
+ mangle_pstate_invalid_compat_toggle: name fix
+ mangle_pstate_invalid_mode_el[1-3]: precautionary zeroing PSTATE.MODE
+ fake_sigreturn_bad_magic, fake_sigreturn_bad_size,
fake_sigreturn_bad_size_for_magic0:
- accounting for available space...dropping extra when needed
- keeping alignent
- new testcases on FPSMID context:

[PATCH RESEND v3 0/2] selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)
by Ilya Leoshkevich
Hello,
Is there anything blocking this from getting merged?
This patch series fixes the following problem:
linux# make kselftest TARGETS=bpf O=/mnt/linux-build
# selftests: bpf: test_libbpf.sh
# ./test_libbpf.sh: line 23: ./test_libbpf_open: No such file or directory
# test_libbpf: failed at file test_l4lb.o
# selftests: test_libbpf [FAILED]
Patch 1 appends / to $(OUTPUT) in order to make it more uniform with the
rest of the tree.
Patch 2 fixes the problem by prepending $(OUTPUT) to all members of
$(TEST_PROGS).
v1->v2:
- Append / to $(OUTPUT).
- Use $(addprefix) instead of $(foreach).
v2->v3:
- Split the patch in two.
- Improve the commit message.
Ilya Leoshkevich (2):
selftests: append / to $(OUTPUT)
selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)

[PATCH v2] selftests: add tests for clone3()
by Adrian Reber
This adds tests for clone3() with different values and sizes
of struct clone_args.
This selftest was initially part of of the clone3() with PID selftest.
After that patch was almost merged Eugene sent out a couple of patches
to fix problems with these test.
This commit now only contains the clone3() selftest after the LPC
decision to rework clone3() with PID to allow setting the PID in
multiple PID namespaces including all of Eugene's patches.

v2:
- Applied Christian's suggestions
- Skip root-only tests when running as non-root

[PATCH] selftests/livepatch: filter 'taints' from dmesg comparison
by Joe Lawrence
The livepatch selftests compare expected dmesg output to verify kernel
behavior. They currently filter out "tainting kernel with
TAINT_LIVEPATCH" messages which may be logged when loading livepatch
modules.
Further filter the log to also drop "loading out-of-tree module taints
kernel" messages in case the klp_test modules have been build without
the in-tree module flag.
Signed-off-by: Joe Lawrence <joe.lawrence(a)redhat.com>
---
Note: I stumbled across this in a testing scenario and thought it might
be generally useful to extend this admittedly fragile mechanism. Since
there are no related livepatch-core changes, this can go through Shuah's
kselftest tree if she prefers. -- Joe

[PATCH net-next v2] selftest: net: add some traceroute tests
by fruggeri＠arista.com
Added the following traceroute tests.
IPV6:
Verify that in this scenario
------------------------ N2
| |
------ ------ N3 ----
| R1 | | R2 |------|H2|
------ ------ ----
| |
------------------------ N1
|
----
|H1|
----
where H1's default route goes through R1 and R1's default route goes
through R2 over N2, traceroute6 from H1 to H2 reports R2's address
on N2 and not N1.
IPV4:
Verify that traceroute from H1 to H2 shows 1.0.1.1 in this scenario
1.0.3.1/24
---- 1.0.1.3/24 1.0.1.1/24 ---- 1.0.2.1/24 1.0.2.4/24 ----
|H1|--------------------------|R1|--------------------------|H2|
---- N1 ---- N2 ----
where net.ipv4.icmp_errors_use_inbound_ifaddr is set on R1 and
1.0.3.1/24 and 1.0.1.1/24 are respectively R1's primary and secondary
address on N1.
v2: fixed some typos, and have bridge in R1 instead of R2 in IPV6 test.

[PATCH linux-kselftest/test v1] apparmor: add AppArmor KUnit tests for policy unpack
by Brendan Higgins
From: Mike Salvatore <mike.salvatore(a)canonical.com>
Add KUnit tests to test AppArmor unpacking of userspace policies.
AppArmor uses a serialized binary format for loading policies. To find
policy format documentation see
Documentation/admin-guide/LSM/apparmor.rst.
In order to write the tests against the policy unpacking code, some
static functions needed to be exposed for testing purposes. One of the
goals of this patch is to establish a pattern for which testing these
kinds of functions should be done in the future.

Sorry in advanced for emailing so many people. I suspect that there are
quite a few people who will be interested in this discussion - not so
much because of the AppArmor test itself - but because I think this
patch offers a good place to discuss how we should/will need to handle
code visibility for the purpose of writing tests.
I fully expect there to be a great deal of discussion on this patch
especially on the topic of visibility and how to expose symbols for
testing. Based on conversations I had before sending this patch out, I
expect to see a number of different suggestions on how to test symbols
that are not normally exposed.

[PATCH net-next] selftest: net: add some traceroute tests
by fruggeri＠arista.com
Added the following traceroute tests.
IPV6:
Verify that in this scenario
------------------------ N2
| |
------ ------ N3 ----
| R1 | | R2 |------|H2|
------ ------ ----
| |
------------------------ N1
|
----
|H1|
----
where H1's default route goes through R1 and R1's default route goes
through R2 over N2, traceroute6 from H1 to H2 reports R2's address
on N2 and not N1.
IPV4:
Verify that traceroute from H1 to H2 shows 1.0.1.1 in this scenario
1.0.3.1/24
---- 1.0.1.3/24 1.0.1.1/24 ---- 1.0.2.1/24 1.0.2.4/24 ----
|H1|--------------------------|R1|--------------------------|H2|
---- N1 ---- N2 ----
where net.ipv4.icmp_errors_use_inbound_ifaddr is set on R1 and
1.0.3.1/24 and 1.0.1.1/24 are respectively R1's primary and secondary
address on N1.

[PATCH 00/19] mm/gup: track dma-pinned pages: FOLL_PIN, FOLL_LONGTERM
by John Hubbard
Hi,
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-4: refactoring and preparatory cleanup, independent fixes
(Patch 4: V4L2-core bug fix (can be separately applied))
* Patch 5: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 6-11: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 12: Activate tracking of FOLL_PIN pages.
* Patches 13-15: convert FOLL_LONGTERM callers
* Patches: 16-17: gup_benchmark and run_vmtests support
* Patch 18: enforce FOLL_LONGTERM as a gup-internal (only) flag
* Patch 19: Documentation/vm/pin_user_pages.rst
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH linux-kselftest/test v6] lib/list-test: add a test for the 'list' doubly linked list
by David Gow
Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).

Question about where to put test drivers
by Ralph Campbell
I'm planning to add some kernel self tests which use a user level program
in tools/testing/selftests/vm/ and a kernel module. See:
https://lore.kernel.org/linux-mm/20191023195515.13168-1-rcampbell@nvidia.co…
The question is where to put the kernel module source code.
I see some test modules that are in lib/test_*.ko and my patch
initially placed the hmm-dmirror module in drivers/char/ since
it creates a character device.
Any advice?

[PATCH v7 1/9] hugetlb_cgroup: Add hugetlb_cgroup reservation counter
by Mina Almasry
These counters will track hugetlb reservations rather than hugetlb
memory faulted in. This patch only adds the counter, following patches
add the charging and uncharging of the counter.
Problem:
Currently tasks attempting to allocate more hugetlb memory than is available get
a failure at mmap/shmget time. This is thanks to Hugetlbfs Reservations [1].
However, if a task attempts to allocate hugetlb memory only more than its
hugetlb_cgroup limit allows, the kernel will allow the mmap/shmget call,
but will SIGBUS the task when it attempts to fault the memory in.
We have developers interested in using hugetlb_cgroups, and they have expressed
dissatisfaction regarding this behavior. We'd like to improve this
behavior such that tasks violating the hugetlb_cgroup limits get an error on
mmap/shmget time, rather than getting SIGBUS'd when they try to fault
the excess memory in.
The underlying problem is that today's hugetlb_cgroup accounting happens
at hugetlb memory *fault* time, rather than at *reservation* time.
Thus, enforcing the hugetlb_cgroup limit only happens at fault time, and
the offending task gets SIGBUS'd.
Proposed Solution:
A new page counter named hugetlb.xMB.reservation_[limit|usage]_in_bytes. This
counter has slightly different semantics than
hugetlb.xMB.[limit|usage]_in_bytes:
- While usage_in_bytes tracks all *faulted* hugetlb memory,
reservation_usage_in_bytes tracks all *reserved* hugetlb memory and
hugetlb memory faulted in without a prior reservation.
- If a task attempts to reserve more memory than limit_in_bytes allows,
the kernel will allow it to do so. But if a task attempts to reserve
more memory than reservation_limit_in_bytes, the kernel will fail this
reservation.
This proposal is implemented in this patch series, with tests to verify
functionality and show the usage. We also added cgroup-v2 support to
hugetlb_cgroup so that the new use cases can be extended to v2.
Alternatives considered:
1. A new cgroup, instead of only a new page_counter attached to
the existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code
duplication with hugetlb_cgroup. Keeping hugetlb related page counters under
hugetlb_cgroup seemed cleaner as well.
2. Instead of adding a new counter, we considered adding a sysctl that modifies
the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do accounting at
reservation time rather than fault time. Adding a new page_counter seems
better as userspace could, if it wants, choose to enforce different cgroups
differently: one via limit_in_bytes, and another via
reservation_limit_in_bytes. This could be very useful if you're
transitioning how hugetlb memory is partitioned on your system one
cgroup at a time, for example. Also, someone may find usage for both
limit_in_bytes and reservation_limit_in_bytes concurrently, and this
approach gives them the option to do so.
Testing:
- Added tests passing.
- libhugetlbfs tests mostly passing, but some tests have trouble with and
without this patch series. Seems environment issue rather than code:

[BUGFIX PATCH] selftests: breakpoints: Fix a typo of function name
by Masami Hiramatsu
Since commit 5821ba969511 ("selftests: Add test plan API to kselftest.h
and adjust callers") accidentally introduced 'a' typo in the front of
run_test() function, breakpoint_test_arm64.c became not able to be
compiled.
Remove the 'a' from arun_test().

[PATCH v2] kernel-doc: rename the kernel-doc directive 'functions' to 'identifiers'
by Changbin Du
The 'functions' directive is not only for functions, but also works for
structs/unions. So the name is misleading. This patch renames it to
'identifiers', which specific the functions/types to be included in
documentation. We keep the old name as an alias of the new one before
all documentation are updated.

v2:
o use 'identifiers' as the new directive name.

[PATCH] selftests: add tests for clone3()
by Adrian Reber
This adds tests for clone3() with different values and sizes
of struct clone_args.
This selftest was initially part of of the clone3() with PID selftest.
After that patch was almost merged Eugene sent out a couple of patches
to fix problems with these test.
This commit now only contains the clone3() selftest after the LPC
decision to rework clone3() with PID to allow setting the PID in
multiple PID namespaces including all of Eugene's patches.

[BUGFIX PATCH v3 0/5] selftests: Fixes for 32bit arch
by Masami Hiramatsu
Hi,
Here are the 3rd version of kselftest fixes some on 32bit arch
(e.g. arm)
In this version, I updated [1/5] to make va_max 1MB unconditionally
according to Alexey's comment.
When I built the ksefltest on arm, I hit some 32bit related warnings.
Here are the patches to fix those issues.
- [1/5] va_max was set 2^32 even on 32bit arch. This can make
va_max == 0 and always fail. Make it 1GB unconditionally.
- [2/5] Some VM tests requires 64bit user space, which should
not run on 32bit arch.
- [3/5] For counting the size of large file, we should use
size_t instead of unsinged long.
- [4/5] Gcc warns printf format for size_t and int64_t on
32bit arch. Use %llu and cast it.
- [5/5] Gcc warns __u64 and pointer type castings. It should
once translated to unsigned long.
Thank you,
---

[PATCH] selftests: gen_kselftest_tar.sh: Do not clobber kselftest/
by Kees Cook
The default installation location for gen_kselftest_tar.sh was still
"kselftest/" which collides with the existing directory. Instead, this
moves the installation target into "kselftest_install/kselftest/" and
adjusts the tar creation accordingly. This also adjusts indentation and
logic to be consistent.
Fixes: 42d46e57ec97 ("selftests: Extract single-test shell logic from lib.mk")

[PATCH v4 0/6] lib/string: Add strscpy_pad() function
by Tobin C. Harding
Hi Shua,
Here is the set with cleanup as suggested by Kees on v3.
Configured, built, and tested all modules loaded by
tools/testing/selftests/lib/*.sh
>From previous cover letters ...
While doing the testing for strscpy_pad() it was noticed that there is
duplication in how test modules are being fed to kselftest and also in
the test modules themselves.
This set makes an attempt at adding a framework to kselftest for writing
kernel test modules. It also adds a script for use in creating script
test runners for kselftest. My macro-foo is not great, all criticism
and suggestions very much appreciated. The design is based on test
modules lib/test_printf.c, lib/test_bitmap.c, lib/test_xarray.c.
Changes since last version:
- Remove dependency on Bash (thanks Kees)
- Use oneliner to implement kselftest test runners (thanks Kees)
- Squash patch that adds kselftest script creator script with patch
that uses it.
- Fix typos (thanks Randy)
- Add Kees' Acked-by tags to all patches
thanks,
Tobin.
Tobin C. Harding (6):
lib/test_printf: Add empty module_exit function
kselftest: Add test runner creation script
kselftest: Add test module framework header
lib: Use new kselftest header
lib/string: Add strscpy_pad() function
lib: Add test module for strscpy_pad

[PATCH linux-kselftest/test v7] lib/list-test: add a test for the 'list' doubly linked list
by David Gow
Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).

---
This revision, v7, renames tests with 'for_each' in their name to have
'for__each' instead. This works around the checkpatch.pl bug Shuah
mentioned, as checkpatch.pl believes that function definitions with
'for_each' in the name are actually loops, and wants the '{' on the
previous line.
With this change, checkpatch is perfectly happy.

[PATCH v1] selftest/trustedkeys: TPM 1.2 trusted keys test
by Mimi Zohar
Create, save and load trusted keys test
Signed-off-by: Mimi Zohar <zohar(a)linux.ibm.com>
Change log v1:
- Replace the directions for using Trousers to take ownership of the TPM
with directions for using the IBM TSS.
- Differentiate between different types of errors. Recent bug is causing
"add_key: Timer expired".

[PATCH v23 14/24] selftests/x86: Add a selftest for SGX
by Jarkko Sakkinen
Add a selftest for SGX. It is a trivial test where a simple enclave
copies one 64-bit word of memory between two memory locations given to
the enclave as arguments. Use ENCLS[EENTER] to invoke the enclave.

v14: [<https://lore.kernel.org/lkml/20191010054140.8483-1-cyphar@cyphar.com/>]
* The magic-link changes (and O_EMPTYPATH) have been dropped from this series
-- they will be developed and sent separately. The main reason is that we
need to restrict things other than open(2) (examples include truncate(2) as
well as mount(MS_BIND)). This will require a fair amount of extra work, and
there's no point stalling openat2(2) for that work to be completed.
* Minor rework of 'struct open_how':
* To avoid future headaches, make it a non-const argument.
* Expand ->flags and ->resolve to 64-bit fields to allow for more flag
extensions without needing to add separate fields too early. This
requires adding a bit of explicit padding (32 bits) to avoid userspace
putting garbage in the alignment padding -- this can be repurposed for
future extensions.
* upgrade_mask is dropped (and will be a separate field when we add it
again in the future) to avoid userspace foot-guns.
* Expand -EINVAL checks in build_open_flags(). Rather than silently
ignoring silly flag combinations (such as O_TMPFILE|O_PATH or
O_PATH|<most flags>), give an -EINVAL. All of the silent ignore semantics
were added to open(2) because we couldn't return -EINVAL -- but we can
now!
* open(2) and openat(2) clean up their flags before passing them to
build_open_flags(), so all mixed flags will continue to work. There is
one exception which is (O_PATH|O_TMPFILE) -- this is no longer
permitted (as far as I can tell this appears to be a bug, and there are
no userspace users that I've hit after running this code for a few
days). If it turns out that userspace does depend on (O_PATH|O_TMPFILE)
working, we can only disallow it for openat2(2).
* Don't zero out nd->root in complete_walk() for RCU-walk if we're doing a
scoped-lookup (this prevents a needless REF-walk retry).
* Attempt all tests on kernels that don't have openat2(2), rather than just
skipping everything.

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the direc-
tory referred to by the file descriptor dirfd (or the current working directory of the
calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then
dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is
resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not con-
tain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see path_resolu-
tion(7) for background information.) The primary use case for these flags
is to allow trusted programs to restrict how untrusted paths (or paths in-
side untrusted directories) are resolved. The full list of resolve flags is
given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as bind mounts are
very widely used by end-users. Setting this flag indiscrimnately for
all uses of openat2() may result in spurious errors on previously-
functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as symbolic links
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on previ-
ously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly open-
ing these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of path-
name) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute sym-
bolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root perma-
nently for a process), RESOLVE_IN_ROOT allows a program to effi-
ciently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are han-
dled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or poten-
tial attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new ex-
tension fields will always be appended, the size will always increase.) This extensibil-
ity design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel sup-
ports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-compatibil-
ity.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all ex-
tensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported ex-
tension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of exten-
sions. However, if a userspace program wishes to determine what extensions the running
kernel supports, they may conduct a binary search on size (to find the largest value which
doesn't produce an error of E2BIG.)

[PATCH AUTOSEL 5.3 96/99] mm/gup_benchmark: add a missing "w" to getopt string
by Sasha Levin
From: John Hubbard <jhubbard(a)nvidia.com>
[ Upstream commit 6f24c8d30d08f270b54f4c2cb9b08dfccbe59c57 ]
Even though gup_benchmark.c has code to handle the -w command-line option,
the "w" is not part of the getopt string. It looks as if it has been
missing the whole time.
On my machine, this leads naturally to the following predictable result:
$ sudo ./gup_benchmark -w
./gup_benchmark: invalid option -- 'w'
...which is fixed with this commit.

[PATCH AUTOSEL 5.3 29/99] selftests/bpf: Set rp_filter in test_flow_dissector
by Sasha Levin
From: Jiri Benc <jbenc(a)redhat.com>
[ Upstream commit fd418b01fe26c2430b1091675cceb3ab2b52e1e0 ]
Many distributions enable rp_filter. However, the flow dissector test
generates packets that have 1.1.1.1 set as (inner) source address without
this address being reachable. This causes the selftest to fail.

Linux-5.4: bpf: test_core_reloc_arrays.o: Segmentation fault with llc -march=bpf
by Prabhakar Kushwaha
Adding other mailing list, folks...
Hi All,
I am trying to build kselftest on Linux-5.4 on ubuntu 18.04. I installed
LLVM-9.0.0 and Clang-9.0.0 from below links after following steps from
[1] because of discussion [2]
https://releases.llvm.org/9.0.0/llvm-9.0.0.src.tar.xz
https://releases.llvm.org/9.0.0/clang-tools-extra-9.0.0.src.tar.xz
https://releases.llvm.org/9.0.0/cfe-9.0.0.src.tar.xz
Now, i am trying with llc -march=bpf, with this segmentation fault is
coming as below:

It looks to be something related llc and more than 1 dimension array.
has anyone faced such error.
Please suggest!!

kthread: make __kthread_queue_delayed_work static
The __kthread_queue_delayed_work is not exported so
make it static, to avoid the following sparse warning:
kernel/kthread.c:869:6: warning: symbol
'__kthread_queue_delayed_work' was not declared. Should it be static?

[PATCH] selftests/livepatch: Disable the timeout
by Miroslav Benes
Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") introduced a timeout per test. Livepatch tests could
run longer than 45 seconds, especially on slower machines. They do not
hang and they detect if something goes awry with internal accounting.
Better than looking for an arbitrary value, just disable the timeout for
livepatch selftests.

[PATCH AUTOSEL 4.19 04/37] rseq/selftests: x86: Work-around bogus gcc-8 optimisation
by Sasha Levin
From: Mathieu Desnoyers <mathieu.desnoyers(a)efficios.com>
[ Upstream commit fe22983d92c15253ea8eb854acbe863fc2313759 ]
gcc-8 version 8.1.0, 8.2.0, and 8.3.0 generate broken assembler with asm
goto that have a thread-local storage "m" input operand on both x86-32
and x86-64. For instance:
__thread int var;
static int fct(void)
{
asm goto ( "jmp %l[testlabel]\n\t"
: : [var] "m" (var) : : testlabel);
return 0;
testlabel:
return 1;
}
int main()
{
return fct();
}
% gcc-8 -O2 -o test-asm-goto test-asm-goto.c
/tmp/ccAdHJbe.o: In function `main':
test-asm-goto.c:(.text.startup+0x1): undefined reference to `.L2'
collect2: error: ld returned 1 exit status
% gcc-8 -m32 -O2 -o test-asm-goto test-asm-goto.c
/tmp/ccREsVXA.o: In function `main':
test-asm-goto.c:(.text.startup+0x1): undefined reference to `.L2'
collect2: error: ld returned 1 exit status
Work-around this compiler bug in the rseq-x86.h header by passing the
address of the __rseq_abi TLS as a register operand rather than using
the "m" input operand.

[REVIEW PATCH v5 3/3] tests: add close_range() tests
by Christian Brauner
This adds basic tests for the new close_range() syscall.
- test that no invalid flags can be passed
- test that a range of file descriptors is correctly closed
- test that a range of file descriptors is correctly closed if there there
are already closed file descriptors in the range
- test that max_fd is correctly capped to the current fdtable maximum

[PATCH v9 00/12] Add arm64/signal initial kselftest support
by Cristian Marussi
Hi
this patchset aims to add the initial arch-specific arm64 support to
kselftest starting with signals-related test-cases.
This series is based on v5.4-rc2.
A common internal test-case layout is proposed for signal tests and it is
wired-up to the toplevel kselftest Makefile, so that it should be possible
at the end to run it on an arm64 target in the usual way with KSFT.
~/linux# make TARGETS=arm64 kselftest
New KSFT arm64 testcases live inside tools/testing/selftests/arm64 grouped
by family inside subdirectories: arm64/signal is the first family proposed
with this series.
This series converts also to this subdirectory scheme the pre-existing
KSFT arm64 tags tests (already merged in v5.3), moving them into their own
arm64/tags subdirectory.
Thanks
Cristian
Notes:
-----
- further details in the included READMEs
- more tests still to be written (current strategy is going through the
related Kernel signal-handling code and write a test for each possible
and sensible code-path)
A few ideas for more TODO testcases:
- mangle_pstate_invalid_ssbs_regs: mess with SSBS bits on every
possible configured behavior
- fake_sigreturn_unmapped_sp: SP into unmapped addrs
- fake_sigreturn_kernelspace_sp: SP into kernel addrs
- fake_sigreturn_sve_bad_extra_context: SVE extra context badly formed
- fake_sigreturn_misaligned_sp_4: misaligned SP by 4
(i.e., __alignof__(struct _aarch64_ctx))
- fake_sigreturn_misaligned_sp_8: misaligned SP by 8
(i.e., sizeof(struct _aarch64_ctx))
- fake_sigreturn_bad_size_non_aligned: a size that doesn't overflow
__reserved[], but is not a multiple of 16
- fake_sigreturn_bad_size_tiny: a size that is less than 16
- fake_sigreturn_bad_size_overflow_tiny: a size that does overflow
__reserved[], but by less than 16 bytes?
- mangle_sve_invalid_extra_context: SVE extra_context invalid
- SVE signal testcases and special handling will be part of an additional patch
still to be released
- KSFT arm64 tags test patch
https://lore.kernel.org/linux-arm-kernel/c1e6aad230658bc175b42d92daeff2e300…
is relocated into its own directory under tools/testing/selftests/arm64/tags
Changes:
--------
v8-->v9:
- fixed a couple of misplaced .gitignore
v7-->v8:
- removed SSBS test case
- split remnants of SSBS patch (v7 05/11), containing some helpers,
into two distinct patches
v6-->v7:
- rebased on v5.4-rc2
- renamed SUBTARGETS arm64/ toplevel Makefile ENV to ARM64_SUBTARGETS
- fixed fake_sigreturn alignment routines (off by one)
- fixed SSBS test: avoid using MRS/MSR as whole and SKIP when SSBS not
supported
- reporting KSFT_SKIP when needed (usually if test_init(0 fails)
- using ID_AA64PFR1_EL1.SSBS to check SSBS support instead of HWCAP_SSBS
v5-->v6:
- added arm64 toplevel Makefile SUBTARGETS env var to be able to selectively
build only some arm64/ tests subdirectories
- removed unneed toplevel Makefile exports and fixed Copyright
- better checks for supported features and features names helpers
- converted some run-time critical assert() to abort() to avoid
issues when -NDEBUG is set
- default_handler() signal handler refactored and split
- using SIGTRAP for get_current_context()
- use volatile where proper
- refactor and relocate test_init() invocation
- review usage of MRS SSBS instructions depending on HW_SSBS
- cleanup fake_sigreturn trampoline
- cleanup get_starting_header helper
- avoiding timeout test failures wherever possible (fail immediately
if possible)
v4-->v5:
- rebased on arm64/for-next-core merging 01/11 with KSFT tags tests:
commit 9ce1263033cd ("selftests, arm64: add a selftest for passing tagged pointers to kernel")
- moved .gitignore up on elevel
- moved kernel header search mechanism into KSFT arm64 toplevel Makefile
so that it can be used easily also by each arm64 KSFT subsystem inside

[PATCH v14 0/6] open: introduce openat2(2) syscall
by Aleksa Sarai
This patchset is being developed here:
<https://github.com/cyphar/linux/tree/openat2/master>
Patch changelog:
v14:
* The magic-link changes (and O_EMPTYPATH) have been dropped from this series
-- they will be developed and sent separately. The main reason is that we
need to restrict things other than open(2) (examples include truncate(2) as
well as mount(MS_BIND)). This will require a fair amount of extra work, and
there's no point stalling openat2(2) for that work to be completed.
* Minor rework of 'struct open_how':
* To avoid future headaches, make it a non-const argument.
* Expand ->flags and ->resolve to 64-bit fields to allow for more flag
extensions without needing to add separate fields too early. This
requires adding a bit of explicit padding (32 bits) to avoid userspace
putting garbage in the alignment padding -- this can be repurposed for
future extensions.
* upgrade_mask is dropped (and will be a separate field when we add it
again in the future) to avoid userspace foot-guns.
* Expand -EINVAL checks in build_open_flags(). Rather than silently
ignoring silly flag combinations (such as O_TMPFILE|O_PATH or
O_PATH|<most flags>), give an -EINVAL. All of the silent ignore semantics
were added to open(2) because we couldn't return -EINVAL -- but we can
now!
* open(2) and openat(2) clean up their flags before passing them to
build_open_flags(), so all mixed flags will continue to work. There is
one exception which is (O_PATH|O_TMPFILE) -- this is no longer
permitted (as far as I can tell this appears to be a bug, and there are
no userspace users that I've hit after running this code for a few
days). If it turns out that userspace does depend on (O_PATH|O_TMPFILE)
working, we can only disallow it for openat2(2).
* Don't zero out nd->root in complete_walk() for RCU-walk if we're doing a
scoped-lookup (this prevents a needless REF-walk retry).
* Attempt all tests on kernels that don't have openat2(2), rather than just
skipping everything.

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the
directory referred to by the file descriptor dirfd (or the current working directory of
the calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute,
then dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname
is resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not
contain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see
path_resolution(7) for background information.) The primary use case for
these flags is to allow trusted programs to restrict how untrusted paths (or
paths inside untrusted directories) are resolved. The full list of resolve
flags is given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable
(unless it is used for a specific security purpose), as bind mounts
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on
previously-functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable
(unless it is used for a specific security purpose), as symbolic
links are very widely used by end-users. Setting this flag
indiscrimnately for all uses of openat2() may result in spurious
errors on previously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly
opening these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of
pathname) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute
symbolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root
permanently for a process), RESOLVE_IN_ROOT allows a program to
efficiently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are
handled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or
potential attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new
extension fields will always be appended, the size will always increase.) This
extensibility design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel
supports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-
compatibility.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all
extensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported
extension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of
extensions. However, if a userspace program wishes to determine what extensions the
running kernel supports, they may conduct a binary search on size (to find the largest
value which doesn't produce an error of E2BIG.)

[PATCH v2 linux-kselftest-test 0/3] kunit: support building core/tests as modules
by Alan Maguire
The current kunit execution model is to provide base kunit functionality
and tests built-in to the kernel. The aim of this series is to allow
building kunit itself and tests as modules. This in turn allows a
simple form of selective execution; load the module you wish to test.
In doing so, kunit itself (if also built as a module) will be loaded as
an implicit dependency.
Because this requires a core API modification - if a module delivers
multiple suites, they must be declared with the kunit_test_suites()
macro - we're proposing this patch as a candidate to be applied to the
test tree before too many kunit consumers appear. We attempt to deal
with existing consumers in patch 1.
Changes since v1:
- sent correct patch set; apologies, previous patch set was built
prior to kunit move to lib/ and should be ignored.
Patch 1 consists changes needed to support loading tests as modules.
Patch 2 allows kunit itself to be loaded as a module.
Patch 3 documents module support.
Alan Maguire (3):
kunit: allow kunit tests to be loaded as a module
kunit: allow kunit to be loaded as a module
kunit: update documentation to describe module-based build

[PATCH linux-kselftest/test v5] lib/list-test: add a test for the 'list' doubly linked list
by David Gow
Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).
Signed-off-by: David Gow <davidgow(a)google.com>
---
v5 replaces the use of KUNIT_ASSERT_NOT_ERR_OR_NULL() -- to check the
return value from kzalloc() and kmalloc() -- with the __GFP_NOFAIL
arugment. (Both in the list_test_list_init test.)
Earlier versions of the test can be found:

[PATCH linux-kselftest/test v4] lib/list-test: add a test for the 'list' doubly linked list
by David Gow
Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).
Signed-off-by: David Gow <davidgow(a)google.com>
---
The changes from v3 are mostly to do with naming:
- The Kconfig entry has been renamed from LIST_TEST to LIST_KUNIT_TEST,
which matches the SYSCTL_KUNIT_TEST entry,
- The Kconfig description was updated to better match other KUnit tests,
specifying that the test is not intended for use in a production
kernel. A now-redundant mention of the test running a boot was
removed.
- The MAINTAINERS entry refers to a "KUNIT TEST" rather than a "UNIT
TEST"
- The module name has changed from "list-test" to "list-kunit-test".
Earlier versions of the test can be found:

[BUGFIX PATCH v2 0/5] selftests: Fixes for 32bit arch
by Masami Hiramatsu
Hi,
Here are the 2nd version of kselftest fixes some on 32bit arch
(e.g. arm). In this version, I updated [1/5] to make va_max 1GB
instead of 3GB, according to Alexey's comment.
When I built the ksefltest on arm, I hit some 32bit related warnings.
Here are the patches to fix those issues.
- [1/5] va_max was set 2^32 even on 32bit arch. This can make
va_max == 0 and always fail. Make it 3GB on 32bit.
- [2/5] Some VM tests requires 64bit user space, which should
not run on 32bit arch.
- [3/5] For counting the size of large file, we should use
size_t instead of unsinged long.
- [4/5] Gcc warns printf format for size_t and int64_t on
32bit arch. Use %llu and cast it.
- [5/5] Gcc warns __u64 and pointer type castings. It should
once translated to unsigned long.
Thank you,
---

[PATCH 0/1] mm/gup_benchmark: fix MAP_HUGETLB case
by John Hubbard
Hi,
Here's another gup_benchmark.c fix, which I ran into while adding
support for the upcoming FOLL_PIN work. Anyway, the problem is
clearly described in the patch commit description, and the fix seems
like the best way to me, but the fix is not *completely* black and
white.
This fix forces MAP_ANONYMOUS for the MAP_HUGETLB case. However,
another way to do it might be to mmap() against a valid hugetlb
page file, instead of /dev/zero. But that seems like a lot of
trouble and if I'm reading the intent correctly, MAP_ANONYMOUS
is what's desired anyway.

Linux-5.4: bpf: test_core_reloc_arrays.o: Segmentation fault with llc -march=bpf

Hi All,

$$INSTALL_PATH is always NULL. It should be $INSTALL_PATH instead
$$INSTALL_PATH.

[PATCH 2/2][SRU][DISCO][EOAN] UBUNTU: SAUCE: seccomp: fix SECCOMP_USER_NOTIF_FLAG_CONTINUE test
by Christian Brauner
BugLink: https://bugs.launchpad.net/bugs/1849281
The ifndef for SECCOMP_USER_NOTIF_FLAG_CONTINUE was placed under the
ifndef for the SECCOMP_FILTER_FLAG_NEW_LISTENER feature. This will not
work on systems that do support SECCOMP_FILTER_FLAG_NEW_LISTENER but do not
support SECCOMP_USER_NOTIF_FLAG_CONTINUE. So move the latter ifndef out of
the former ifndef's scope.

[PATCH v3 1/2] clone3: add CLONE_CLEAR_SIGHAND
by Christian Brauner
Reset all signal handlers of the child not set to SIG_IGN to SIG_DFL.
Mutually exclusive with CLONE_SIGHAND to not disturb other thread's
signal handler.
In the spirit of closer cooperation between glibc developers and kernel
developers (cf. [2]) this patchset came out of a discussion on the glibc
mailing list for improving posix_spawn() (cf. [1], [3], [4]). Kernel
support for this feature has been explicitly requested by glibc and I
see no reason not to help them with this.
The child helper process on Linux posix_spawn must ensure that no signal
handlers are enabled, so the signal disposition must be either SIG_DFL
or SIG_IGN. However, it requires a sigprocmask to obtain the current
signal mask and at least _NSIG sigaction calls to reset the signal
handlers for each posix_spawn call or complex state tracking that might
lead to data corruption in glibc. Adding this flags lets glibc avoid
these problems.

[3]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00158.html
[4]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00160.html
[2]: https://lwn.net/Articles/799331/
'[...] by asking for better cooperation with the C-library projects
in general. They should be copied on patches containing ABI
changes, for example. I noted that there are often times where
C-library developers wish the kernel community had done things
differently; how could those be avoided in the future? Members of
the audience suggested that more glibc developers should perhaps
join the linux-api list. The other suggestion was to "copy Florian
on everything".'

[PATCH v6 1/9] hugetlb_cgroup: Add hugetlb_cgroup reservation counter
by Mina Almasry
These counters will track hugetlb reservations rather than hugetlb
memory faulted in. This patch only adds the counter, following patches
add the charging and uncharging of the counter.
Problem:
Currently tasks attempting to allocate more hugetlb memory than is available get
a failure at mmap/shmget time. This is thanks to Hugetlbfs Reservations [1].
However, if a task attempts to allocate hugetlb memory only more than its
hugetlb_cgroup limit allows, the kernel will allow the mmap/shmget call,
but will SIGBUS the task when it attempts to fault the memory in.
We have developers interested in using hugetlb_cgroups, and they have expressed
dissatisfaction regarding this behavior. We'd like to improve this
behavior such that tasks violating the hugetlb_cgroup limits get an error on
mmap/shmget time, rather than getting SIGBUS'd when they try to fault
the excess memory in.
The underlying problem is that today's hugetlb_cgroup accounting happens
at hugetlb memory *fault* time, rather than at *reservation* time.
Thus, enforcing the hugetlb_cgroup limit only happens at fault time, and
the offending task gets SIGBUS'd.
Proposed Solution:
A new page counter named hugetlb.xMB.reservation_[limit|usage]_in_bytes. This
counter has slightly different semantics than
hugetlb.xMB.[limit|usage]_in_bytes:
- While usage_in_bytes tracks all *faulted* hugetlb memory,
reservation_usage_in_bytes tracks all *reserved* hugetlb memory and
hugetlb memory faulted in without a prior reservation.
- If a task attempts to reserve more memory than limit_in_bytes allows,
the kernel will allow it to do so. But if a task attempts to reserve
more memory than reservation_limit_in_bytes, the kernel will fail this
reservation.
This proposal is implemented in this patch series, with tests to verify
functionality and show the usage. We also added cgroup-v2 support to
hugetlb_cgroup so that the new use cases can be extended to v2.
Alternatives considered:
1. A new cgroup, instead of only a new page_counter attached to
the existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code
duplication with hugetlb_cgroup. Keeping hugetlb related page counters under
hugetlb_cgroup seemed cleaner as well.
2. Instead of adding a new counter, we considered adding a sysctl that modifies
the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do accounting at
reservation time rather than fault time. Adding a new page_counter seems
better as userspace could, if it wants, choose to enforce different cgroups
differently: one via limit_in_bytes, and another via
reservation_limit_in_bytes. This could be very useful if you're
transitioning how hugetlb memory is partitioned on your system one
cgroup at a time, for example. Also, someone may find usage for both
limit_in_bytes and reservation_limit_in_bytes concurrently, and this
approach gives them the option to do so.
Testing:
- Added tests passing.
- libhugetlbfs tests mostly passing, but some tests have trouble with and
without this patch series. Seems environment issue rather than code:

[PATCH] seccomp: fix SECCOMP_USER_NOTIF_FLAG_CONTINUE test
by Christian Brauner
The ifndef for SECCOMP_USER_NOTIF_FLAG_CONTINUE was placed under the
ifndef for the SECCOMP_FILTER_FLAG_NEW_LISTENER feature. This will not
work on systems that do support SECCOMP_FILTER_FLAG_NEW_LISTENER but do not
support SECCOMP_USER_NOTIF_FLAG_CONTINUE. So move the latter ifndef out of
the former ifndef's scope.

[BUGFIX PATCH 0/5] selftests: Fixes for 32bit arch
by Masami Hiramatsu
Hi,
Here are some patches to fix some warnings/issues on 32bit arch
(e.g. arm).
When I built the ksefltest on arm, I hit some 32bit related warnings.
Here are the patches to fix those issues.
- [1/5] va_max was set 2^32 even on 32bit arch. This can make
va_max == 0 and always fail. Make it 3GB on 32bit.
- [2/5] Some VM tests requires 64bit user space, which should
not run on 32bit arch.
- [3/5] For counting the size of large file, we should use
size_t instead of unsinged long.
- [4/5] Gcc warns printf format for size_t and int64_t on
32bit arch. Use %llu and cast it.
- [5/5] Gcc warns __u64 and pointer type castings. It should
once translated to unsigned long.
Thank you,
---

Linux-5.4: bpf: test_core_reloc_arrays.o: Segmentation fault with llc -march=bpf

Hi All,
I am trying to build kselftest on Linux-5.4 on ubuntu 18.04. I installed
LLVM-9.0.0 and Clang-9.0.0 from below links after following steps from

[Bug report] "make run_tests -C bpf" hanging forever
by Liu Yiding
Hi All.
The patch 5c069b6dedef "selftests: Move test output to diagnostic lines"
from Apr 24, 2019,
leads to `make run_tests -C bpf` hanging forever.
Bpf includes many subtest, when cmd `make run_tests -C bpf` runs to
test_lwt_seg6local.sh, task will hang and runner.sh never run next task.
I checked ps aux, prefix.pl will never exit.
```

91066 [ 3620.461986] Thu Oct 17 14:54:05 CST 2019 detected soft_timeout
```
Ignore test_lwt_seg6local and run `make run_tests -C bpf` again, task
will hang on test_tc_tunnel.sh.
Kushwaha also meet this issue, `make run_tests -C bpf` hang on
test_lwt_ip_encap.sh (This test failed on my localhost).

Linux-5.4-rc3+: bpf: progs/test_core_reloc_ints.c:32:6: error: using builtin_preserve_access_index() without -g

Hi All,
I am trying to build kselftest on Linux-5.4-rc3+ on ubuntu 18.04. I
installed LLVM-9.0.0 and Clang-9.0.0 from below links after following
steps from [1] because of discussion [2]

Plan for hybrid testing
by Brendan Higgins
Hey Knut and Shuah,
Following up on our offline discussion on Wednesday night:
We decided that it would make sense for Knut to try to implement Hybrid
Testing (testing that crosses the kernel userspace boundary) that he
introduced here[1] on top of the existing KUnit infrastructure.
We discussed several possible things in the kernel that Knut could test
with the new Hybrid Testing feature as an initial example. Those were
(in reverse order of expected difficulty):
1. RDS (Reliable Datagram Sockets) - We decided that, although this was
one of the more complicated subsystems to work with, it was probably
the best candidate for Knut to start with because it was in desperate
need of better testing, much of the testing would require crossing
the kernel userspace boundary to be effective, and Knut has access to
RDS (since he works at Oracle).
2. KMOD - Probably much simpler than RDS, and the maintainer, Luis
Chamberlain (CC'ed) would like to see better testing here, but
probably still not as good as RDS because it is in less dire need of
testing, collaboration on this would be more difficult, and Luis is
currently on an extended vacation. Luis and I had already been
discussing testing KMOD here[2].
3. IP over USB - Least desirable option, but still possible. More
complicated than KMOD, and not as easy to collaborate on as RDS.
I don't really think we discussed how this would work. I remember that I
mentioned that it would be easier if I sent out a patch that
centralizes where KUnit tests are dispatched from in the kernel; I will
try to get an RFC for that out, probably sometime next week. That should
provide a pretty straightforward place for Knut to move his work on top
of.
The next question is what the userspace component of this should look
like. To me it seems like we should probably have the kselftest test
runner manage when the test gets run, and collecting and reporting the
result of the test, but I think Knut has thought more about this than I,
and Shuah is the kselftest maintainer, so I am guessing this will
probably mostly be a discussion between the two of you.
So I think we have a couple of TODOs between us:
Brendan:
- Need to send out patch that provides a single place where all tests
are dispatched from.
Knut:
- Start splitting out the hybrid test stuff from the rest of the RFC
you sent previously.
Knut and Shuah:
- Start figuring out what the userspace component of this will look
like.
Cheers!

That way, we make it super easy for people to run the unit tests. Since most users are used using make targets, this I bet will significantly increase the number of developers using kunit, because it will be super-duper convenient for them.

Having something like --allconfig is the ultimate goal. I had been
talking to Luis and Shuah about this for some time.
I think the best way to make this work would be for kunit_tool to be
able to detect all the tests with CONFIG_KUNIT as you suggest (or
something like it). Luis actually already suggested it; however, we
identified that this would likely not be as easy as it sounds as it is
possible to have mutually exclusive CONFIGs. Luis pointed out that
some researchers are currently working on a sat solver for Kconfig
that we could use to potentially address this problem. Nevertheless, a
complete solution in this regard is actually somewhat difficult.
Shuah's solution was just to use CONFIG fragments in the meantime
similar to what kselftest already does. I was leaning in that
direction since kselftest already does that and we know that it works.
Shuah, Luis, does this still match what you have been thinking?

Because the kernel developer will want to be running unit tests as well as building kernels that can be run under whatever architecture they are normally developing for (for example, an x86 kernel that can be run using kvm; or a arm64 kernel that gets run on an Android device by using the "fastboot" command). So that means we don't want to be overwriting the object files and .config files for building the kernel for x86 when building the kunit kernel using the um arch. For example, for ext4, my ideal workflow might go something like this:

Yeah, I encountered this before. Some file is not getting properly
cleaned up by `make mrproper`. It works if you do `git clean -fdx` (I
know that's not a real solution for most people). Nevertheless, it
sounds like we need to sit down and actually solve this problem since
it is affecting users now.
I think you make a compelling argument. Anyone else have any thoughts on this?

[PATCH AUTOSEL 5.3 23/89] selftests/kselftest/runner.sh: Add 45 second timeout per test
by Sasha Levin
From: Kees Cook <keescook(a)chromium.org>
[ Upstream commit 852c8cbf34d3b3130a05c38064dd98614f97d3a8 ]
Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per
test") solves the problem of kselftest_harness.h-using binary tests
possibly hanging forever. However, scripts and other binaries can still
hang forever. This adds a global timeout to each test script run.
To make this configurable (e.g. as needed in the "rtc" test case),
include a new per-test-directory "settings" file (similar to "config")
that can contain kselftest-specific settings. The first recognized field
is "timeout".
Additionally, this splits the reporting for timeouts into a specific
"TIMEOUT" not-ok (and adds exit code reporting in the remaining case).

[PATCH linux-kselftest/test v2] lib/list-test: add a test for the 'list' doubly linked list
by David Gow
Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).
Signed-off-by: David Gow <davidgow(a)google.com>
---
Addressed the various comments on v1. The biggest change is the renaming
of all of the testcases from the form x_test to list_test_x. I'm not
super happy with how that looks (not the least because it ends up with
'list' twice), but it is more consistent with the proc/sysctl tests.

[PATCH 1/2] pidfd: verify task is alive when printing fdinfo
by Christian Brauner
Currently, when a task is dead we still print the pid it used to use in
the fdinfo files of its pidfds. This doesn't make much sense since the
pid may have already been reused. So verify that the task is still
alive. If the task is not alive anymore, we will print -1. This allows
us to differentiate between a task not being present in a given pid
namespace - in which case we already print 0 - and a task having been
reaped.
Note that this uses PIDTYPE_PID for the check. Technically, we could've
checked PIDTYPE_TGID since pidfds currently only refer to thread-group
leaders but if they won't anymore in the future then this check becomes
problematic without it being immediately obvious to non-experts imho. If
a thread is created via clone(CLONE_THREAD) than struct pid has a single
non-empty list pid->tasks[PIDTYPE_PID] and this pid can't be used as a
PIDTYPE_TGID meaning pid->tasks[PIDTYPE_TGID] will return NULL even
though the thread-group leader might still be very much alive. We could
be more complicated and do something like:
bool alive = false;
rcu_read_lock();
struct task_struct *tsk = pid_task(pid, PIDTYPE_PID);
if (tsk && task_tgid(tsk))
alive = true;
rcu_read_unlock();
but it's really not worth it. We already have created a pidfd and we
thus know it refers to a thread-group leader. Checking PIDTYPE_PID is
fine and is easier to maintain should we ever allow pidfds to refer to
threads.

[PATCH v2] selftests: Add kselftest-all and kselftest-install targets
by Shuah Khan
Add kselftest-all target to build tests from the top level
Makefile. This is to simplify kselftest use-cases for CI and
distributions where build and test systems are different.
Current kselftest target builds and runs tests on a development
system which is a developer use-case.
Add kselftest-install target to install tests from the top level
Makefile. This is to simplify kselftest use-cases for CI and
distributions where build and test systems are different.
This change addresses requests from developers and testers to add
support for installing kselftest from the main Makefile.
In addition, make the install directory the same when install is
run using "make kselftest-install" or by running kselftest_install.sh.
Also fix the INSTALL_PATH variable conflict between main Makefile and
selftests Makefile.
Signed-off-by: Shuah Khan <skhan(a)linuxfoundation.org>

Changes since v1:
- Collpased two patches that added separate targets to
build and install into one patch using pattern rule to
invoke all, install, and clean targets from main Makefile.

[PATCH linux-kselftest/test v6] ext4: add kunit test for decoding extended timestamps
by Iurii Zaikin
KUnit tests for decoding extended 64 bit timestamps that verify the
seconds part of [a/c/m] timestamps in ext4 inode structs are decoded
correctly.
Test data is derived from the table in the Inode Timestamps section of
Documentation/filesystems/ext4/inodes.rst.
KUnit tests run during boot and output the results to the debug log
in TAP format (http://testanything.org/). Only useful for kernel devs
running KUnit test harness and are not for inclusion into a production
build.

[PATCH linux-kselftest/test v5] ext4: add kunit test for decoding extended timestamps
by Iurii Zaikin
KUnit tests for decoding extended 64 bit timestamps
that verify the seconds part of [a/c/m]
timestamps in ext4 inode structs are decoded correctly.
KUnit tests, which run on boot and output
the results to the debug log in TAP format (http://testanything.org/).
are only useful for kernel devs running KUnit test harness. Not for
inclusion into a production build.
Test data is derived from the table under
Documentation/filesystems/ext4/inodes.rst Inode Timestamps.

[PATCH v3 0/3] ftrace: Introduce PERMANENT ftrace_ops flag
by Miroslav Benes
Livepatch uses ftrace for redirection to new patched functions. It means
that if ftrace is disabled, all live patched functions are disabled as
well. Toggling global 'ftrace_enabled' sysctl thus affect it directly.
It is not a problem per se, because only administrator can set sysctl
values, but it still may be surprising.
Introduce PERMANENT ftrace_ops flag to amend this. If the
FTRACE_OPS_FL_PERMANENT is set on any ftrace ops, the tracing cannot be
disabled by disabling ftrace_enabled. Equally, a callback with the flag
set cannot be registered if ftrace_enabled is disabled.
v2->v3:
- ftrace_enabled explicitly set to true
- selftest from Joe Lawrence (I just split it to two patches)
- typo fix
v1->v2:
- different logic, proposed by Joe Lawrence
Joe Lawrence (2):
selftests/livepatch: Make dynamic debug setup and restore generic
selftests/livepatch: Test interaction with ftrace_enabled

[PATCH linux-kselftest/test v3] lib/list-test: add a test for the 'list' doubly linked list
by David Gow
Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).
Signed-off-by: David Gow <davidgow(a)google.com>
---
Note: v2 can be found here:
https://lkml.org/lkml/2019/10/10/1011
This revision fixes some issues with the memory allocation in the
'list_test_list_init' test. In particular, it uses a KUnit assert to
verify that the lists allocated with kmalloc() and kzalloc() are
non-NULL (and also properly passes GFP_KERNEL to them).
Since this depends on KUnit, which is not yet upstream, it probably
makes sense for it to go into the linux-kselftest/test branch alongside
KUnit itself. v2 has ended up in the -mm tree, and is already in -next,
though. I think it nevertheless makes sense to move this change to the
linux-kselftest/test branch, as outlined here:
https://lore.kernel.org/linux-kselftest/CABVgOS=W4cfFoE=JT4mbk1zkUsreucrw_B…
Thanks,
-- David

Apologies for the delay, mostly due to Thanksgiving in Canada. You should be able to start using Tools/KUnit now. It uses a default virtual assignee tools_kunit(a)kernel-bugs.kernel.org, so to start receiving bugmail for it, please follow instructions on this page:

[PATCH linux-kselftest/test v4] ext4: add kunit test for decoding extended timestamps
by Iurii Zaikin
KUnit tests for decoding extended 64 bit timestamps
that verify the seconds part of [a/c/m]
timestamps in ext4 inode structs are decoded correctly.
KUnit tests, which run on boot and output
the results to the debug log in TAP format (http://testanything.org/).
are only useful for kernel devs running KUnit test harness. Not for
inclusion into a production build.
Test data is derive from the table under
Documentation/filesystems/ext4/inodes.rst Inode Timestamps.

[PATCH linux-kselftest/test v3] ext4: add kunit test for decoding extended timestamps
by Iurii Zaikin
KUnit tests for decoding extended 64 bit timestamps
that verify the seconds part of [a/c/m]
timestamps in ext4 inode structs are decoded correctly.
KUnit tests, which run on boot and output
the results to the debug log in TAP format (http://testanything.org/).
are only useful for kernel devs running KUnit test harness. Not for
inclusion into a production build.
Test data is derive from the table under
Documentation/filesystems/ext4/inodes.rst Inode Timestamps.

[PATCH] kernel-doc: rename the kernel-doc directive 'functions' to 'specific'
by Changbin Du
The 'functions' directive is not only for functions, but also works for
structs/unions. So the name is misleading. This patch renames it to
'specific', so now we have export/internal/specific directives to limit
the functions/types to be included in documentation. Meanwhile we improved
the warning message.

[PATCH] selftests: Fix O= and KBUILD_OUTPUT handling for relative paths

Fix O= and KBUILD_OUTPUT handling for relative paths.

In both of these cases, targets get built in ../kselftest_size which is

[PATCH] pidfd: fix selftest compilation by removing linux/wait.h
by Christian Kellner
From: Christian Kellner <christian(a)kellner.me>
The pidfd_{open,poll}_test.c files both include `linux/wait.h` and
later `sys/wait.h`. The former has `#define P_ALL 0`, but in the
latter P_ALL is part of idtype_t enum, where it gets substituted
due to the aforementioned define to be `0`, which then results in
`typedef enum {0, ...`, which then results into a compiler error:
"error: expected identifier before numeric constant".
Since we need `sys/wait.h` for waitpid, drop `linux/wait.h`.

[ANN] New git repository for Autogenerated regression tests
by Shuah Khan
I created a new kernel.org repository for compiling and preserving
Autogenerated regression tests. This is an outcome based on decision
made at the Maintainer Summit to preserve and use the autogenerated
reproducers for regression testing.
Linux Kernel Autogenerated Regression Tests
===========================================
linux-arts repository is dedicated to preserving the autogenerated
regression tests for regression testing.
Automates testing entities such as Syzbot generate reproducers to test
the kernel. It is a manual process to download reproducers and once the
bug is fixed, kernel developers loose track of these reproducers.
As per the decision made at a session at the Maintainers Summit 2019,
this git repository is created to preserve the reproducers.
Please find the details on the discussion that lead to this decision
at https://lwn.net/Articles/799162/
Please find the new git repo at:
https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-arts.git/
The initial commit pulls in Syzkaller reproducers from Dmitry Vyukov.
As per Dmitry's request, the run and build scripts have been updated
to with just the syzbot link.
Thanks Dmitry for compiling these reproducers and working on the
framework of running and building them.
As for reproducers, each .c is specific to syzbot report and named
with the syzbot bug report ID.
Please play with it and let me know if you have questions. README
has the details on where to send patches and regressions tests.
thanks,
-- Shuah

[PATCH v2] riscv: add support for SECCOMP and SECCOMP_FILTER
by David Abdurachmanov
This patch was extensively tested on Fedora/RISCV (applied by default on
top of 5.2-rc7 kernel for <2 months). The patch was also tested with 5.3-rc
on QEMU and SiFive Unleashed board.
libseccomp (userspace) was rebased:
https://github.com/seccomp/libseccomp/pull/134
Fully passes libseccomp regression testing (simulation and live).
There is one failing kernel selftest: global.user_notification_signal
v1 -> v2:
- return immediatly if secure_computing(NULL) returns -1
- fixed whitespace issues
- add missing seccomp.h
- remove patch #2 (solved now)
- add riscv to seccomp kernel selftest

kseltest: bpf: test_lwt_ip_encap.sh: Why -l used in test_gso
by Prabhakar Kushwaha
Hi All,
I am trying to understand test_gso test for IPv4 and IPv6 with following
piece of code
# listen on IPv*_DST, capture TCP into $TMPFILE
if [ "${PROTO}" == "IPv4" ] ; then
IP_DST=${IPv4_DST}
ip netns exec ${NS3} bash -c \
"nc -4 -l -s ${IPv4_DST} -p 9000 > ${TMPFILE} &"
elif [ "${PROTO}" == "IPv6" ] ; then
IP_DST=${IPv6_DST}
ip netns exec ${NS3} bash -c \
"nc -6 -l -s ${IPv6_DST} -p 9000 > ${TMPFILE} &"
RET=$?
else
echo " test_gso: unknown PROTO: ${PROTO}"
fi
I have couple of queries around it
a) why -l is being used for reading listen on IPv*_DST with -s option.
I was looking at https://www.computerhope.com/unix/nc.htm, following has
been mentioned:
-l : Used to specify that nc should listen for an incoming connection
rather than initiate a connection to a
remote host. It is an error to use this option in conjunction with the
-p, -s, or -z options.
Additionally, any timeouts specified with the -w option are ignored.
b) Even if there is requirement of -l option to use. can we provide
timeout option also. how? as -w dont work with -l.
I am facing an issue with Linux-5.3 Kselftest where even if
test_lwt_ip_encap.sh "exit", bpf/runner.sh is not
running next test case. It just wait until CRTL + c is pressed.
If I comment above code things work fine.
Please sugggest

Bugzilla Component for KUnit?
by Brendan Higgins
Hi,
I am thinking about requesting a Bugzilla component for my kernel
project KUnit. I am not sure if this is the right place for it. Some
background on KUnit: We are working on adding unit testing for the Linux
kernel[1][2]. We have our initial patchset that introduces the subsystem
in the process of being merged (Linus sent our PR back to us for a minor
fix[3], so it should be in either 5.4-rc2 or 5.5, but is nevertheless in
linux-next). However, we also have a staging repo that people are using
and some supporting code that lives outside of the kernel.
So I am trying to figure out:
1. Is it appropriate to request a Bugzilla component before our
subsystem has been merged into torvalds/master? I would just wait,
but I have some users looking to file issues, so I would prefer to
provide them something sooner rather than later.
2. Is it appropriate to use the kernel's Bugzilla to track issues
outside of the Linux kernel? As I mention above, we have code that
lives outside of the kernel; is it appropriate to use kernel.org's
Bugzilla for this?
3. Does Bugzilla match my planned usage model? It doesn't look like
Bugzilla get's much usage aside from reporting bugs. I want to use
it for tracking feature progress and things like that. Is that okay?
If kernel.org's Bugzilla is not a fit for what I want to do, that's
fine. I just want to make sure before I go off and potentially fracture
a central bug repository by creating my own somewhere else.
Thanks!

[PATCH v2 0/2] gup.c, gup_benchmark.c trivial fixes before the storm
by John Hubbard
Hi,
Changes since v1:
1) Fixed a krobot-reported mistake, which also uncovered a pre-existing
bug. Thanks to Kirill for recommending the fix.
2) Added another small fix: changed the data type to unsigned int, as
pointed out by Ira.
2) Added a "Fixes:" line, thanks to Kirill and Aneesh for pinpointing the
commit.
3) Collected Acked-by and Suggested-by's.
Original cover letter, edited slightly
======================================
These trivial fixes apply to today's linux.git (5.4-rc3).
I found these while polishing up the Next And Final get_user_pages()+dma
tracking patchset (which is in final testing and passing nicely...so far).
Anyway, as these two patches apply cleanly both before and after the larger
gup/dma upcoming patchset, I thought it best to send this out separately,
in order to avoid muddying the waters more than usual.

[PATCH v5 0/7] hugetlb_cgroup: Add hugetlb_cgroup reservation limits
by Mina Almasry
Patch series implements hugetlb_cgroup reservation usage and limits, which
track hugetlb reservations rather than hugetlb memory faulted in. Details of
the approach is 1/7.
Changes in v5:
- Moved the bulk of the description to the first patch in the series.
- Clang formatted the entire series.
- Split off 'hugetlb: remove duplicated code' and 'hugetlb: region_chg provides
only cache entry' into their own patch series.
- Added comments to HUGETLB_RES enum.
- Fixed bug in 'hugetlb: disable region_add file_region coalescing' calculating
the wrong number of regions_needed in some cases.
- Changed sleeps in test to proper conditions.
- Misc fixes in test based on shuah@ review.
Changes in v4:
- Split up 'hugetlb_cgroup: add accounting for shared mappings' into 4 patches
for better isolation and context on the indvidual changes:
- hugetlb_cgroup: add accounting for shared mappings
- hugetlb: disable region_add file_region coalescing
- hugetlb: remove duplicated code
- hugetlb: region_chg provides only cache entry
- Fixed resv->adds_in_progress accounting.
- Retained behavior that region_add never fails, in earlier patchsets region_add
could return failure.
- Fixed libhugetlbfs failure.
- Minor fix to the added tests that was preventing them from running on some
environments.
Changes in v3:
- Addressed comments of Hillf Danton:
- Added docs.
- cgroup_files now uses enum.
- Various readability improvements.
- Addressed comments of Mike Kravetz.
- region_* functions no longer coalesce file_region entries in the resv_map.
- region_add() and region_chg() refactored to make them much easier to
understand and remove duplicated code so this patch doesn't add too much
complexity.
- Refactored common functionality into helpers.
Changes in v2:
- Split the patch into a 5 patch series.
- Fixed patch subject.
Mina Almasry (7):
hugetlb_cgroup: Add hugetlb_cgroup reservation counter
hugetlb_cgroup: add interface for charge/uncharge hugetlb reservations
hugetlb_cgroup: add reservation accounting for private mappings
hugetlb: disable region_add file_region coalescing
hugetlb_cgroup: add accounting for shared mappings
hugetlb_cgroup: Add hugetlb_cgroup reservation tests

Hi,
These trivial fixes apply to today's linux.git (5.4-rc3, or maybe -rc4, by

[PATCH 1/2] clone3: add CLONE3_CLEAR_SIGHAND
by Christian Brauner
Reset all signal handlers of the child not set to SIG_IGN to SIG_DFL.
Mutually exclusive with CLONE_SIGHAND to not disturb other thread's
signal handler.
In the spirit of closer cooperation between glibc developers and kernel
developers (cf. [2]) this patchset came out of a discussion on the glibc
mailing list for improving posix_spawn() (cf. [1], [3], [4]). Kernel
support for this feature has been explicitly requested by glibc and I
see no reason not to help them with this.
The child helper process on Linux posix_spawn must ensure that no signal
handlers are enabled, so the signal disposition must be either SIG_DFL
or SIG_IGN. However, it requires a sigprocmask to obtain the current
signal mask and at least _NSIG sigaction calls to reset the signal
handlers for each posix_spawn call or complex state tracking that might
lead to data corruption in glibc. Adding this flags lets glibc avoid
these problems.

'[...] by asking for better cooperation with the C-library projects
in general. They should be copied on patches containing ABI
changes, for example. I noted that there are often times where
C-library developers wish the kernel community had done things
differently; how could those be avoided in the future? Members of
the audience suggested that more glibc developers should perhaps
join the linux-api list. The other suggestion was to "copy Florian
on everything".'

[PATCH v2 2/2] pidfd: add tests for NSpid info in fdinfo
by Christian Kellner
From: Christian Kellner <christian(a)kellner.me>
Add tests that check that if pid namespaces are configured the fdinfo
file of a pidfd contains an NSpid: entry containing the process id
in the current and additionally all nested namespaces.
