[PATCH bpf 0/2] selftests/bpf: add missing CONFIG values to test config

by Alan Maguire

Selftests "config" file is intended to represent the config required to run the tests; a few values are missing for the BPF selftests and these can result in test failures due to missing helpers etc. Add the missing values as they will help document the config needed for a clean BPF selftests run.

[PATCH] selftests/bpf: add general instructions for test execution

by Alan Maguire

Getting a clean BPF selftests run involves ensuring latest trunk LLVM/clang are used, pahole is recent (>=1.16) and config matches the specified config file as closely as possible. Add to bpf_devel_QA.rst and point tools/testing/selftests/bpf/README.rst to it.

[PATCH V2 00/19] Miscellaneous fixes for resctrl selftests

by Sai Praneeth Prakhya

This patch set has several miscellaneous fixes to resctrl selftest tool that are easily visible to user. V1 had fixes to CAT test and CMT test but they were dropped in V2 because having them here made the patchset humongous. So, changes to CAT test and CMT test will be posted in another patchset. Some warnings reported by sparse tool were fixed in this patchset but some are not yet fixed. They will be fixed in another patchset. Patches 1 to 14, 18 and 19 are independent fixes.

[PATCH] selftests/exec: Add binfmt_script regression test

by Kees Cook

While working on commit b5372fe5dc84 ("exec: load_script: Do not exec truncated interpreter path"), I wrote a series of test scripts to verify corner cases. However, soon after, commit 6eb3c3d0a52d ("exec: increase BINPRM_BUF_SIZE to 256") landed, resulting in the tests needing to be refactored for the larger BINPRM_BUF_SIZE, which got lost on my TODO list. During the recent exec refactoring work[1], the need for these tests resurfaced, so I've finished them up for addition to the kernel selftests.

[PATCH v2] selftests: introduce gen_tar Makefile target

by Veronika Kabatova

The gen_kselftest_tar.sh always packages *all* selftests and doesn't pass along any variables to `make install` to influence what should be built. This can result in an early error on the command line ("Unknown tarball format TARGETS=XXX"), or unexpected test failures as the tarball contains tests people wanted to skip on purpose. Since the makefile already contains all the logic, we can add a target for packaging. Keep the default .gz target the script uses, and actually extend the supported formats by using tar's autodetection. To not break current workflows, keep the gen_kselftest_tar.sh script as it is, with an added suggestion to use the makefile target instead.

[PATCH v2] mm/hmm/test: use xa_for_each_range instead of looping

by Ralph Campbell

The test driver uses an xa_array to store virtual to physical address translations for a simulated hardware device. The MMU notifier invalidation callback is used to keep the table consistent with the CPU page table and is frequently called only for a page or two. However, if the test process exits unexpectedly or is killed, the range can be [0..ULONG_MAX] in which case calling xa_erase() for every possible PFN results in CPU timeouts. Use xa_for_each_range() to efficiently erase entries in the range.

[PATCH 0/2] selftests/vm: minor fixes for 5.7-rc5

by John Hubbard

Here's a couple of tiny fixes, just so we can cleanly build selftests/vm. These apply to today's linux.git. Some merge notes: * The .gitignore fix is appropriate for linux.git, but it is a subset of what's required for linux-next and mmotm. In order to fix things now in linux.git, and keep it fixed in mmotm and linux-next, but without manual intervention required in git merges, I'm adding the missing item ("mremap_dontunmap") to the *top* of .gitignore for this patch. And then I'll send a separate patch to be applied to mmotm and linux-next, that will also add a different item ("khugepaged") to the *bottom* of .gitignore. * The write_to_hugetlbfs.c fix is already applied to linux-next, but doesn't seem to be getting picked up for linux.git. Maybe it's in the merge pipeline, but if not, let's fix it here, before the -rc cycle is over.

[PATCH v5 0/7] firmware: add partial read support in request_firmware_into_buf

by Scott Branden

Please consider this version series ready for upstream acceptance. This patch series adds partial read support in request_firmware_into_buf. In order to accept the enhanced API it has been requested that kernel selftests and upstreamed driver utilize the API enhancement and so are included in this patch series. Also in this patch series is the addition of a new Broadcom VK driver utilizing the new request_firmware_into_buf enhanced API. Changes from v4: - handle reset issues if card crashes - allow driver to have min required msix - add card utilization information Changes from v3: - fix sparse warnings - fix printf format specifiers for size_t - fix 32-bit cross-compiling reports 32-bit shifts - use readl/writel,_relaxed to access pci ioremap memory, removed memory barriers and volatile keyword with such change - driver optimizations for interrupt/poll functionalities Changes from v2: - remove unnecessary code and mutex locks in lib/test_firmware.c - remove VK_IOCTL_ACCESS_BAR support from driver and use pci sysfs instead - remove bitfields - remove Kconfig default m - adjust formatting and some naming based on feedback - fix error handling conditions - use appropriate return codes - use memcpy_toio instead of direct access to PCIE bar Scott Branden (7): fs: introduce kernel_pread_file* support firmware: add offset to request_firmware_into_buf test_firmware: add partial read support for request_firmware_into_buf firmware: test partial file reads of request_firmware_into_buf bcm-vk: add bcm_vk UAPI misc: bcm-vk: add Broadcom VK driver MAINTAINERS: bcm-vk: add maintainer for Broadcom VK Driver MAINTAINERS | 7 + drivers/base/firmware_loader/firmware.h | 5 + drivers/base/firmware_loader/main.c | 52 +- drivers/misc/Kconfig | 1 + drivers/misc/Makefile | 1 + drivers/misc/bcm-vk/Kconfig | 29 + drivers/misc/bcm-vk/Makefile | 12 + drivers/misc/bcm-vk/bcm_vk.h | 435 +++++ drivers/misc/bcm-vk/bcm_vk_dev.c | 1256 +++++++++++++++ drivers/misc/bcm-vk/bcm_vk_legacy.c | 89 + drivers/misc/bcm-vk/bcm_vk_msg.c | 1425 +++++++++++++++++ drivers/misc/bcm-vk/bcm_vk_msg.h | 196 +++ drivers/misc/bcm-vk/bcm_vk_sg.c | 271 ++++ drivers/misc/bcm-vk/bcm_vk_sg.h | 60 + drivers/misc/bcm-vk/bcm_vk_tty.c | 352 ++++ drivers/soc/qcom/mdt_loader.c | 7 +- fs/exec.c | 96 +- include/linux/firmware.h | 8 +- include/linux/fs.h | 20 + include/uapi/linux/misc/bcm_vk.h | 99 ++ lib/test_firmware.c | 144 +- .../selftests/firmware/fw_filesystem.sh | 80 + 22 files changed, 4596 insertions(+), 49 deletions(-) create mode 100644 drivers/misc/bcm-vk/Kconfig create mode 100644 drivers/misc/bcm-vk/Makefile create mode 100644 drivers/misc/bcm-vk/bcm_vk.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_dev.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_legacy.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_tty.c create mode 100644 include/uapi/linux/misc/bcm_vk.h -- 2.17.1

[PATCH] mm/hmm/test: destroy xa_array instead of looping

by Ralph Campbell

The test driver uses an xa_array to store virtual to physical address translations for a simulated hardware device. The MMU notifier invalidation callback is used to keep the table consistent with the CPU page table and is frequently called only for a page or two. However, if the test process exits unexpectedly or is killed, the range can be [0..ULONG_MAX] in which case calling xa_erase() for every possible PFN results in CPU timeouts. Munmap() can result in a large range being invalidated but in that case, the xa_array is likely to contain entries that need to be invalidated. Check for [0..ULONG_MAX] explicitly and just destroy the whole table. Signed-off-by: Ralph Campbell <rcampbell(a)nvidia.com> --- This patch is based on Jason Gunthorpe's hmm tree and should be folded into the ("mm/hmm/test: add selftest driver for HMM") patch once this patch is reviewed, etc. lib/test_hmm.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/lib/test_hmm.c b/lib/test_hmm.c index 8b36c26b717b..b89852ec3c29 100644 --- a/lib/test_hmm.c +++ b/lib/test_hmm.c @@ -201,7 +201,13 @@ static void dmirror_do_update(struct dmirror *dmirror, unsigned long start, * The XArray doesn't hold references to pages since it relies on * the mmu notifier to clear page pointers when they become stale. * Therefore, it is OK to just clear the entry. + * However, if the entire address space is being invalidated, it + * takes too long to clear them one at a time so destroy the array. */ + if (start == 0 && end == ULONG_MAX) { + xa_destroy(&dmirror->pt); + return; + } for (pfn = start >> PAGE_SHIFT; pfn < (end >> PAGE_SHIFT); pfn++) xa_erase(&dmirror->pt, pfn); } -- 2.20.1

[PATCH 0/4] Kselftest integration into Kernel CI - Part 1

by Shuah Khan

This patch series consists of first round of fixes to integrate Kselftest into Kernel CI. You can find full list of problems in my announcement I sent out last week: https://lkml.org/lkml/2020/2/27/2221 These fixes to android and seccomp tests address relocatable support. However, they will still leave the source directory dirty. android test does headers_install in source directory. This is an easier problem to fix. seccomp on the other hand builds fixdep scripts under scripts/basic and installs headers in the source directory. It is linked to solving bpf relocatable build issue which I haven't given it a lot of thought for now. There is no dependency on source directory for run-time which is what we want. I will apply these kernelci topic branch for testing git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git Shuah Khan (4): selftests: Fix kselftest O=objdir build from cluttering top level objdir selftests: Fix seccomp to support relocatable build (O=objdir) selftests: android: ion: Fix ionmap_test compile error selftests: android: Fix custom install from skipping test progs tools/testing/selftests/Makefile | 4 ++-- tools/testing/selftests/android/Makefile | 2 +- tools/testing/selftests/android/ion/Makefile | 2 +- tools/testing/selftests/seccomp/Makefile | 16 +++------------- 4 files changed, 7 insertions(+), 17 deletions(-) -- 2.20.1

[PATCH RESEND net-next] selftests: fix flower parent qdisc

by Vlad Buslov

Flower tests used to create ingress filter with specified parent qdisc "parent ffff:" but dump them on "ingress". With recent commit that fixed tcm_parent handling in dump those are not considered same parent anymore, which causes iproute2 tc to emit additional "parent ffff:" in first line of filter dump output. The change in output causes filter match in tests to fail. Prevent parent qdisc output when dumping filters in flower tests by always correctly specifying "ingress" parent both when creating and dumping filters.

[PATCH v17 00/10] Landlock LSM

by Mickaël Salaün

Hi, This new patch series brings some improvements and add new tests: Use smaller userspace structures (attributes) to save space, and check at built time that every attribute don't contain hole and are 8-bits aligned. Allow enforcement of empty ruleset, which enables deny-all policies (useful for strict sandboxes). I found that UML may not keep the same internal struct inode for an open file. Because the Landlock filesystem access-control relies on internal kernel states, special architectures such as UML can't support Landlock. Add a new ARCH_EPHEMERAL_STATES to identify such architectures. Add a size_attr_features field to struct landlock_attr_features for self-introspection Switch syscall attribute pointer and size arguments to follow similar syscalls argument order (e.g. bpf, clone3, openat2). The SLOC count is 1288 for security/landlock/ and 1740 for tools/testing/selftest/landlock/ . Test coverage for security/landlock/ is 93.6% of lines. The code not covered only deals with internal kernel errors (e.g. memory allocation) and race conditions. The compiled documentation is available here: https://landlock.io/linux-doc/landlock-v17/security/landlock/index.html This series can be applied on top of v5.7-rc5. This can be tested with CONFIG_SECURITY_LANDLOCK and CONFIG_SAMPLE_LANDLOCK. This patch series can be found in a Git repository here: https://github.com/landlock-lsm/linux/commits/landlock-v17 I would really appreciate constructive comments on this patch series. # Landlock LSM The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Because Landlock is a stackable LSM [2], it makes possible to create safe security sandboxes as new security layers in addition to the existing system-wide access-controls. This kind of sandbox is expected to help mitigate the security impact of bugs or unexpected/malicious behaviors in user-space applications. Landlock empowers any process, including unprivileged ones, to securely restrict themselves. Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic. Landlock also takes inspiration from other OS sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD Pledge/Unveil.

[RFC PATCH] kunit: Support skipped tests

by David Gow

This is a proof-of-concept to support "skipping" tests. The kunit_mark_skipped() macro marks the current test as "skipped", with the provided reason. The kunit_skip() macro will mark the test as skipped, and abort the test. The TAP specification supports this "SKIP directive" as a comment after the "ok" / "not ok" for a test. See the "Directives" section of the TAP spec for details: https://testanything.org/tap-specification.html#directives kunit_tool will parse this SKIP directive, and renders skipped tests in yellow and counts them. Skipped tests do not affect the result for a suite. Signed-off-by: David Gow <davidgow(a)google.com> --- Following on from discussions about the KCSAN test[1], which requires a multi-core/processor system to make sense, it would be useful for tests to be able to mark themselves as "skipped", where tests have runtime dependencies which aren't met. As a proof-of-concept, this patch doesn't implement some things which we'd ideally like to have (e.g., non-static "reasons" for skipping the test, maybe some SKIP macros akin to the EXPECT and ASSERT ones), and the implementation is still pretty hacky, but I though I'd put this out there to see if there are any thoughts on the concept in general.

[PATCH AUTOSEL 5.6 27/62] selftests: fix kvm relocatable native/cross builds and installs

by Sasha Levin

From: Shuah Khan <skhan(a)linuxfoundation.org> [ Upstream commit 66d69e081b526b6a6031f0d3ca8ddff71e5707a5 ] kvm test Makefile doesn't fully support cross-builds and installs. UNAME_M = $(shell uname -m) variable is used to define the target programs and libraries to be built from arch specific sources in sub-directories. For cross-builds to work, UNAME_M has to map to ARCH and arch specific directories and targets in this Makefile. UNAME_M variable to used to run the compiles pointing to the right arch directories and build the right targets for these supported architectures. TEST_GEN_PROGS and LIBKVM are set using UNAME_M variable. LINUX_TOOL_ARCH_INCLUDE is set using ARCH variable. x86_64 targets are named to include x86_64 as a suffix and directories for includes are in x86_64 sub-directory. s390x and aarch64 follow the same convention. "uname -m" doesn't result in the correct mapping for s390x and aarch64. Fix it to set UNAME_M correctly for s390x and aarch64 cross-builds. In addition, Makefile doesn't create arch sub-directories in the case of relocatable builds and test programs under s390x and x86_64 directories fail to build. This is a problem for native and cross-builds. Fix it to create all necessary directories keying off of TEST_GEN_PROGS. The following use-cases work with this change: Native x86_64: make O=/tmp/kselftest -C tools/testing/selftests TARGETS=kvm install \ INSTALL_PATH=$HOME/x86_64 arm64 cross-build: make O=$HOME/arm64_build/ ARCH=arm64 HOSTCC=gcc \ CROSS_COMPILE=aarch64-linux-gnu- defconfig make O=$HOME/arm64_build/ ARCH=arm64 HOSTCC=gcc \ CROSS_COMPILE=aarch64-linux-gnu- all make kselftest-install TARGETS=kvm O=$HOME/arm64_build ARCH=arm64 \ HOSTCC=gcc CROSS_COMPILE=aarch64-linux-gnu- s390x cross-build: make O=$HOME/s390x_build/ ARCH=s390 HOSTCC=gcc \ CROSS_COMPILE=s390x-linux-gnu- defconfig make O=$HOME/s390x_build/ ARCH=s390 HOSTCC=gcc \ CROSS_COMPILE=s390x-linux-gnu- all make kselftest-install TARGETS=kvm O=$HOME/s390x_build/ ARCH=s390 \ HOSTCC=gcc CROSS_COMPILE=s390x-linux-gnu- all No regressions in the following use-cases: make -C tools/testing/selftests TARGETS=kvm make kselftest-all TARGETS=kvm Signed-off-by: Shuah Khan <skhan(a)linuxfoundation.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- tools/testing/selftests/kvm/Makefile | 29 +++++++++++++++++++++++++++- 1 file changed, 28 insertions(+), 1 deletion(-) diff --git a/tools/testing/selftests/kvm/Makefile b/tools/testing/selftests/kvm/Makefile index d91c53b726e60..75dec268787f3 100644 --- a/tools/testing/selftests/kvm/Makefile +++ b/tools/testing/selftests/kvm/Makefile @@ -5,8 +5,34 @@ all: top_srcdir = ../../../..

[PATCH AUTOSEL 5.6 25/62] ftrace/selftests: workaround cgroup RT scheduling issues

by Sasha Levin

From: Alan Maguire <alan.maguire(a)oracle.com> [ Upstream commit 57c4cfd4a2eef8f94052bd7c0fce0981f74fb213 ] wakeup_rt.tc and wakeup.tc tests in tracers/ subdirectory fail due to the chrt command returning: chrt: failed to set pid 0's policy: Operation not permitted. To work around this, temporarily disable grout RT scheduling during ftracetest execution. Restore original value on test run completion. With these changes in place, both tests consistently pass.

[PATCH net-next] selftests: fix flower parent qdisc

by Vlad Buslov

Flower tests used to create ingress filter with specified parent qdisc "parent ffff:" but dump them on "ingress". With recent commit that fixed tcm_parent handling in dump those are not considered same parent anymore, which causes iproute2 tc to emit additional "parent ffff:" in first line of filter dump output. The change in output causes filter match in tests to fail. Prevent parent qdisc output when dumping filters in flower tests by always correctly specifying "ingress" parent both when creating and dumping filters.

[PATCH] kselftests: dmabuf-heaps: Fix confused return value on expected error testing

[PATCH v2] selftests/ftrace: Use /bin/echo instead of built-in echo

by Masami Hiramatsu

Since the built-in echo has different behavior in POSIX shell (dash) and bash, we forcibly use /bin/echo -E (not interpret backslash escapes) by default. This also fixes some test cases which expects built-in echo command since the built-in echo command will share the same pid with the shell. trigger-trace-marker-hist.tc and trigger-trace-marker-synthetic.tc write trace_marker several times to make a histogram with the pid as the key. If we use /bin/echo command, the pid-key is different each time and failed to make a histogram. This changes those test to use "ip" (called address) as a key which should be always same if trace_marker is used. For trigger-trace-marker-synthetic-kernel.tc, this uses built-in echo as a special case, because the test case is based on the wakeup event and the trace_marker event and uses the pid as common-key for those events. In this case, we must use built-in echo to make a short "sleep, wakeup and write" program.

[PATCH] tools/testing: Replace zero-length array with flexible-array

by Gustavo A. R. Silva

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

[PATCH] selftests/ftrace: mark irqsoff_tracer.tc test as unresolved if the test module does not exist

by Po-Hsu Lin

The UNRESOLVED state is much more apporiate than the UNSUPPORTED state for the absence of the test module, as it matches "test was set up incorrectly" situation in the README file. A possible scenario is that the function was enabled (supported by the kernel) but the module was not installed properly, in this case we cannot call this as UNSUPPORTED. This change also make it consistent with other module-related tests in ftrace.

[PATCH v10 0/3] mm/hmm/test: add self tests for HMM

by Ralph Campbell

This series adds basic self tests for HMM and are intended for Jason Gunthorpe's rdma tree since he is making some HMM related changes that this can help test. Changes v9 -> v10: Patches 1 & 2 include Jason's changes from his cover letter: https://lkml.org/lkml/2020/4/21/1320 Patch 3 now adds the files alphbetically and removed the outdated reference to include/uapi/linux. Changes v8 -> v9: Rebased to linux-5.7.0-rc1. Moved include/uapi/linux/test_hmm.h to lib/test_hmm_uapi.h Added calls to release_mem_region() to free device private addresses Applied Jason's suggested changes for v8. Added a check for no VMA read access before migrating to device private memory. Changes v7 -> v8: Rebased to Jason's rdma/hmm tree, plus Jason's 6 patch series "Small hmm_range_fault() cleanups". Applied a number of changes from Jason's comments. Changes v6 -> v7: Rebased to linux-5.6.0-rc6 Reverted back to just using mmu_interval_notifier_insert() and making this series only introduce HMM self tests. Changes v5 -> v6: Rebased to linux-5.5.0-rc6 Refactored mmu interval notifier patches Converted nouveau to use the new mmu interval notifier API Changes v4 -> v5: Added mmu interval notifier insert/remove/update callable from the invalidate() callback Updated HMM tests to use the new core interval notifier API Changes v1 -> v4: https://lore.kernel.org/linux-mm/20191104222141.5173-1-rcampbell@nvidia.com Ralph Campbell (3): mm/hmm/test: add selftest driver for HMM mm/hmm/test: add selftests for HMM MAINTAINERS: add HMM selftests MAINTAINERS | 2 + lib/Kconfig.debug | 13 + lib/Makefile | 1 + lib/test_hmm.c | 1149 ++++++++++++++++++++ lib/test_hmm_uapi.h | 59 + tools/testing/selftests/vm/.gitignore | 1 + tools/testing/selftests/vm/Makefile | 3 + tools/testing/selftests/vm/config | 2 + tools/testing/selftests/vm/hmm-tests.c | 1359 ++++++++++++++++++++++++ tools/testing/selftests/vm/run_vmtests | 16 + tools/testing/selftests/vm/test_hmm.sh | 97 ++ 11 files changed, 2702 insertions(+) create mode 100644 lib/test_hmm.c create mode 100644 lib/test_hmm_uapi.h create mode 100644 tools/testing/selftests/vm/hmm-tests.c create mode 100755 tools/testing/selftests/vm/test_hmm.sh -- 2.25.2

[PATCH v3 0/5] kselftest: Extend vDSO tests

by Vincenzo Frascino

This series extends the kselftests for the vDSO library making sure: that they compile correctly on non x86 platforms, that they can be cross compiled and introducing new tests that verify the correctness of the library. The so extended vDSO kselftests have been verified on all the platforms supported by the unified vDSO library [1]. The only new patch that this series introduces is the first one, patch 2 and patch 3 have already been reviewed in past as part of other series [2] [3].

[PATCH 1/1] selftests/bpf: add cls_redirect classifier

by Lorenz Bauer

cls_redirect is a TC clsact based replacement for the glb-redirect iptables module available at [1]. It enables what GitHub calls "second chance" flows [2], similarly proposed by the Beamer paper [3]. In contrast to glb-redirect, it also supports migrating UDP flows as long as connected sockets are used. cls_redirect is in production at Cloudflare, as part of our own L4 load balancer. We have modified the encapsulation format slightly from glb-redirect: glbgue_chained_routing.private_data_type has been repurposed to form a version field and several flags. Both have been arranged in a way that a private_data_type value of zero matches the current glb-redirect behaviour. This means that cls_redirect will understand packets in glb-redirect format, but not vice versa. The test suite only covers basic features. For example, cls_redirect will correctly forward path MTU discovery packets, but this is not exercised. It is also possible to switch the encapsulation format to GRE on the last hop, which is also not tested. There are two major distinctions from glb-redirect: first, cls_redirect relies on receiving encapsulated packets directly from a router. This is because we don't have access to the neighbour tables from BPF, yet. See forward_to_next_hop for details. Second, cls_redirect performs decapsulation instead of using separate ipip and sit tunnel devices. This avoids issues with the sit tunnel [4] and makes deploying the classifier easier: decapsulated packets appear on the same interface, so existing firewall rules continue to work as expected. The code base started it's life on v4.19, so there are most likely still hold overs from old workarounds. In no particular order: - The function buf_off is required to defeat a clang optimization that leads to the verifier rejecting the program due to pointer arithmetic in the wrong order. - The function pkt_parse_ipv6 is force inlined, because it would otherwise be rejected due to returning a pointer to stack memory. - The functions fill_tuple and classify_tcp contain kludges, because we've run out of function arguments. - The logic in general is rather nested, due to verifier restrictions. I think this is either because the verifier loses track of constants on the stack, or because it can't track enum like variables. 1: https://github.com/github/glb-director/tree/master/src/glb-redirect 2: https://github.com/github/glb-director/blob/master/docs/development/second-… 3: https://www.usenix.org/conference/nsdi18/presentation/olteanu 4: https://github.com/github/glb-director/issues/64 Signed-off-by: Lorenz Bauer <lmb(a)cloudflare.com> --- .../selftests/bpf/prog_tests/cls_redirect.c | 456 +++++++ .../selftests/bpf/progs/test_cls_redirect.c | 1058 +++++++++++++++++ .../selftests/bpf/progs/test_cls_redirect.h | 54 + tools/testing/selftests/bpf/test_progs.h | 7 + 4 files changed, 1575 insertions(+) create mode 100644 tools/testing/selftests/bpf/prog_tests/cls_redirect.c create mode 100644 tools/testing/selftests/bpf/progs/test_cls_redirect.c create mode 100644 tools/testing/selftests/bpf/progs/test_cls_redirect.h diff --git a/tools/testing/selftests/bpf/prog_tests/cls_redirect.c b/tools/testing/selftests/bpf/prog_tests/cls_redirect.c new file mode 100644 index 000000000000..f259085cca6a --- /dev/null +++ b/tools/testing/selftests/bpf/prog_tests/cls_redirect.c @@ -0,0 +1,456 @@ +// SPDX-License-Identifier: GPL-2.0 OR BSD-3-Clause +// Copyright (c) 2020 Cloudflare + +#define _GNU_SOURCE + +#include <arpa/inet.h> +#include <string.h> + +#include <linux/pkt_cls.h> + +#include <test_progs.h> + +#include "progs/test_cls_redirect.h" +#include "test_cls_redirect.skel.h" + +#define ENCAP_IP INADDR_LOOPBACK +#define ENCAP_PORT (1234) + +struct addr_port { + in_port_t port;

[PATCH v2 0/4] kselftest: Extend vDSO tests

by Vincenzo Frascino

This series extends the kselftests for the vDSO library making sure: that they compile correctly on non x86 platforms, that they can be cross compiled and introducing new tests that verify the correctness of the library. The so extended vDSO kselftests have been verified on all the platforms supported by the unified vDSO library [1]. The only new patch that this series introduces is the first one, patch 2 and patch 3 have already been reviewed in past as part of other series [2] [3].

[PATCH v2 0/6] Enable as many KUnit tests as possible

by Anders Roxell

Hi, This patchset will try to enable as many KUnit test fragments as possible for the current .config file.

[PATCH] kunit: Kconfig: enable a KUNIT_RUN_ALL fragment

by Anders Roxell

Make it easier to enable all KUnit fragments. This is needed for kernel test-systems, so its easy to get all KUnit tests enabled and if new gets added they will be enabled as well. Fragments that has to be builtin will be missed if CONFIG_KUNIT_RUN_ALL is set as a module. Adding 'if !KUNIT_RUN_ALL' so individual test can be turned of if someone wants that even though KUNIT_RUN_ALL is enabled.

[PATCH] selftests/ftrace: treat module requirement unmet situation as unsupported

by Po-Hsu Lin

When the required module for the test does not exist, use exit_unsupported instead of exit_unresolved to indicate this test is not supported. By doing this we can make test behaviour in sync with the irqsoff_tracer.tc test in preemptirq, which is also treating module existence in this way. Moreover, the test won't exit with a non-zero return value if the module does not exist.

[PATCH v2 0/2] ftrace/selftest: clean up failure cases

by Alan Maguire

When running the ftrace selftests, 2 failures and 6 unresolved cases were observed. The failures can be avoided by setting a sysctl prior to test execution (fixed in patch 1) and by having unresolved cases not return 0 from ftracetest by default since they indicate an absence of testing modules/programs rather than ftrace issues (patch 2). The latter are classified as "unresolved" tests, which operate differently from "unsupported" tests. For unsupported tests, we note the unsupported count but do not consider the tests as having failed, whereas with unresolved the test run is considered to have failed so returns "not ok" when run via kselftest ("make -C tools/testing/selftest/ftrace run_tests"). Patch 2 aligns the unresolved behaviour with the unsupported; by default, unresolved outcomes do not trigger overall failure, but they can if --fail-unresolved is specified. Changes since v1: - updated patch 1 to use /proc path instead of sysctl (Masami) - updated patch 2 to modify unresolved handling in ftracetest rather than change individual unresolved -> unsupported (Masami) Alan Maguire (2): ftrace/selftests: workaround cgroup RT scheduling issues ftrace/selftest: make unresolved cases cause failure if --fail-unresolved set tools/testing/selftests/ftrace/ftracetest | 30 +++++++++++++++++++++++++++++- 1 file changed, 29 insertions(+), 1 deletion(-) -- 1.8.3.1

Many skips while running kselftest

by vaibhav jadhav

Problem: Many skips while running kselftest example: skip to all lkdtm tests ie 70 off 70 skips. Steps I follow while running kselftest: 1.I downloaded kernel from kernel.org and extracted it. 2.As per the kselftest executing steps, I execute the tests. I get lots of skips. So my question's are: 1.Am I going wrong somewhere while running test? 2.Is there any need to configure the kernel in such a way that it can execute the tests? Example: enabling debug filesystem in kernel configuration for debugging. Thankyou.

[RFC v3 0/3] Fix errors when try to build kvm selftests on specified output

by Xiaoyao Li

Hi Shuah, Hope you're happy with this version that I only touch KVM's Makefile. I attempted to build KVM selftests on a specified dir, unfortunately neither "make O=/path/to/mydir TARGETS=kvm" in tools/testing/selftests, nor "make OUTPUT=/path/to/mydir" in tools/testing/selftests/kvm work. This series aims to fix them. Patch 1 and Patch 3 are the fix patch, please see the seperate for details. While Patch 2 is more or less an fix for the future issue, since it works without Patch 2 currently. Changes in v3: - Drop all the patches that touch things out of KVM - Create OUTPUT dir in KVM's Makefile - Correct the INSTALL_HDR_PATH in KVM's Makefile Changes in v2: https://lore.kernel.org/kvm/20200325140133.103236-1-xiaoyao.li@intel.com/ - fix the no directory issue in lib.mk - make kvm fixes seperate patch - Add the patch to fix linux src tree not clean issue v1: https://lore.kernel.org/kvm/20200315093425.33600-1-xiaoyao.li@intel.com/ Xiaoyao Li (3): kvm: selftests: Fix no directory error when OUTPUT specified kvm: selftests: Use the right INSTALL_HDR_PATH when OUTPUT specified and MAKELEVEL is 0 kvm: selftests: Fix header path when built from parent level with O specified tools/testing/selftests/kvm/Makefile | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) -- 2.20.1

[PATCH net-next 0/3] ptp: Add adjust phase to support phase offset.

by vincent.cheng.xh＠renesas.com

From: Vincent Cheng <vincent.cheng.xh(a)renesas.com> This series adds adjust phase to the PTP Hardware Clock device interface. Some PTP hardware clocks have a write phase mode that has a built-in hardware filtering capability. The write phase mode utilizes a phase offset control word instead of a frequency offset control word. Add adjust phase function to take advantage of this capability.

[PATCH kunit-next] kunit: kunit_tool: Separate out config/build/exec/parse

Add new subcommands to kunit.py to allow stages of the existing 'run' subcommand to be run independently: - 'config': Verifies that .config is a subset of .kunitconfig - 'build': Compiles a UML kernel for KUnit - 'exec': Runs the kernel, and outputs the test results. - 'parse': Parses test results from a file or stdin The 'run' command continues to behave as before.

Oops, good catch! I found that came from the built-in echo command behavior. Bash's echo doesn't interpret the backslash escape, but dash's POSIX-compliant echo does. ----<dash>---- $ a='\1' $ b=`echo $a` $ test "$a" = "$b" && echo "same!" || echo "different" different ----<bash>---- $ a='\1' $ b=`echo $a` $ test "$a" = "$b" && echo "same!" || echo "different" same! OK, I'll fix it. Thank you! -- Masami Hiramatsu <mhiramat(a)kernel.org>

[PATCH v6 00/12] mm/gup: track FOLL_PIN pages

by John Hubbard

Hi, Jan and Kirill: I've tentatively removed your review and ACK, respectively, for patch 12 (the last dump_page patch), because even though they are logically the same as what you reviewed in v5, the base is Matthew's new patch instead of my earlier patch. (Trying to err on the side of caution with these tags.) There is a git repo and branch, for convenience in reviewing: git@github.com:johnhubbard/linux.git track_user_pages_v6 ============================================================ Changes since v5: * Rebased onto Linux 5.6.0-rc1. * Swapped in Matthew Wilcox's more comprehensive dump_page() patch, and moved it later in this series so that it immediately precedes my subsequent dump_page() patch, for slightly easier reviews and commit log history. * Fixed "the last bug!" in the /proc/vmstat patch, by moving the mod_node_page_state() call in put_compound_page() so that it only happens in the FOLL_PIN case. * Added a couple more ACKs from Kirill. * Tweaked the "Future steps" in this cover letter to add a little detail about what comes next. ============================================================ Changes since v4: * Added documentation about the huge page behavior of the new /proc/vmstat items. * Added a missing mode_node_page_state() call to put_compound_head(). * Fixed a tracepoint call in page_ref_sub_return(). * Added a trailing underscore to a URL in pin_user_pages.rst, to fix a broken generated link. * Added ACKs and reviewed-by's from Jan Kara and Kirill Shutemov. * Rebased onto today's linux.git, and * I am experimenting here with "git format-patch --base=<commit>". This generated the "base-commit:" tag you'll see at the end of this cover letter. I was inspired to do so after trying out a new get-lore-mbox.py tool (it's very nice), mentioned in a recent LWN article (https://lwn.net/Articles/811528/ ). That tool relies on the base-commit tag for some things. ============================================================ Changes since v3: * Rebased onto latest linux.git * Added ACKs and reviewed-by's from Kirill Shutemov and Jan Kara. * /proc/vmstat: * Renamed items, after realizing that I hate the previous names: nr_foll_pin_requested --> nr_foll_pin_acquired nr_foll_pin_returned --> nr_foll_pin_released * Removed the CONFIG_DEBUG_VM guard, and collapsed away a wrapper routine: now just calls mod_node_page_state() directly. * Tweaked the WARN_ON_ONCE() statements in mm/hugetlb.c to be more informative, and added comments above them as well. * Fixed gup_benchmark: signed int --> unsigned long. * One or two minor formatting changes. ============================================================ Changes since v2: * Rebased onto linux.git, because the akpm tree for 5.6 has been merged. * Split the tracking patch into even more patches, as requested. * Merged Matthew Wilcox's dump_page() changes into mine, as part of the first patch. * Renamed: page_dma_pinned() --> page_maybe_dma_pinned(), in response to Kirill Shutemov's review. * Moved a WARN to the top of a routine, and fixed a typo in the commit description of patch #7, also as suggested by Kirill. ============================================================ Changes since v1: * Split the tracking patch into 6 smaller patches * Rebased onto today's linux-next/akpm (there weren't any conflicts). * Fixed an "unsigned int" vs. "int" problem in gup_benchmark, reported by Nathan Chancellor. (I don't see it in my local builds, probably because they use gcc, but an LLVM test found the mismatch.) * Fixed a huge page pincount problem (add/subtract vs. increment/decrement), spotted by Jan Kara. ============================================================ There is a reasonable case to be made for merging two of the patches (patches 7 and 8), given that patch 7 provides tracking that has upper limits on the number of pins that can be done with huge pages. Let me know if anyone wants those merged, but unless there is some weird chance of someone grabbing patch 7 and not patch 8, I don't really see the need. Meanwhile, it's easier to review in this form. Also, patch 3 has been revived. Earlier reviewers asked for it to be merged into the tracking patch (one cannot please everyone, heh), but now it's back out on it's own. This activates tracking of FOLL_PIN pages. This is in support of fixing the get_user_pages()+DMA problem described in [1]-[4]. FOLL_PIN support is now in the main linux tree. However, the patch to use FOLL_PIN to track pages was *not* submitted, because Leon saw an RDMA test suite failure that involved (I think) page refcount overflows when huge pages were used. This patch definitively solves that kind of overflow problem, by adding an exact pincount, for compound pages (of order > 1), in the 3rd struct page of a compound page. If available, that form of pincounting is used, instead of the GUP_PIN_COUNTING_BIAS approach. Thanks again to Jan Kara for that idea. Other interesting changes: * dump_page(): added one, or two new things to report for compound pages: head refcount (for all compound pages), and map_pincount (for compound pages of order > 1). * Documentation/core-api/pin_user_pages.rst: removed the "TODO" for the huge page refcount upper limit problems, and added notes about how it works now. Also added a note about the dump_page() enhancements. * Added some comments in gup.c and mm.h, to explain that there are two ways to count pinned pages: exact (for compound pages of order > 1) and fuzzy (GUP_PIN_COUNTING_BIAS: for all other pages). ============================================================ General notes about the tracking patch: This is a prerequisite to solving the problem of proper interactions between file-backed pages, and [R]DMA activities, as discussed in [1], [2], [3], [4] and in a remarkable number of email threads since about 2017. :) 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) unpin_user_page() ============================================================ Future steps: * Convert more subsystems from get_user_pages() to pin_user_pages(). The first probably needs to be bio/biovecs, because any filesystem testing is too difficult without those in place. * Change VFS and filesystems to respond appropriately when encountering dma-pinned pages. * Work with Ira and others to connect this all up with file system leases.

[PATCH v4 0/7] firmware: add partial read support in request_firmware_into_buf

by Scott Branden

This patch series adds partial read support in request_firmware_into_buf. In order to accept the enhanced API it has been requested that kernel selftests and upstreamed driver utilize the API enhancement and so are included in this patch series. Also in this patch series is the addition of a new Broadcom VK driver utilizing the new request_firmware_into_buf enhanced API. Changes from v3: - fix sparse warnings - fix printf format specifiers for size_t - fix 32-bit cross-compiling reports 32-bit shifts - use readl/writel,_relaxed to access pci ioremap memory, removed memory barriers and volatile keyword with such change - driver optimizations for interrupt/poll functionalities Changes from v2: - remove unnecessary code and mutex locks in lib/test_firmware.c - remove VK_IOCTL_ACCESS_BAR support from driver and use pci sysfs instead - remove bitfields - remove Kconfig default m - adjust formatting and some naming based on feedback - fix error handling conditions - use appropriate return codes - use memcpy_toio instead of direct access to PCIE bar Scott Branden (7): fs: introduce kernel_pread_file* support firmware: add offset to request_firmware_into_buf test_firmware: add partial read support for request_firmware_into_buf firmware: test partial file reads of request_firmware_into_buf bcm-vk: add bcm_vk UAPI misc: bcm-vk: add Broadcom VK driver MAINTAINERS: bcm-vk: add maintainer for Broadcom VK Driver MAINTAINERS | 7 + drivers/base/firmware_loader/firmware.h | 5 + drivers/base/firmware_loader/main.c | 52 +- drivers/misc/Kconfig | 1 + drivers/misc/Makefile | 1 + drivers/misc/bcm-vk/Kconfig | 29 + drivers/misc/bcm-vk/Makefile | 12 + drivers/misc/bcm-vk/bcm_vk.h | 412 +++++ drivers/misc/bcm-vk/bcm_vk_dev.c | 1211 ++++++++++++++ drivers/misc/bcm-vk/bcm_vk_legacy.c | 89 ++ drivers/misc/bcm-vk/bcm_vk_msg.c | 1414 +++++++++++++++++ drivers/misc/bcm-vk/bcm_vk_msg.h | 195 +++ drivers/misc/bcm-vk/bcm_vk_sg.c | 271 ++++ drivers/misc/bcm-vk/bcm_vk_sg.h | 60 + drivers/misc/bcm-vk/bcm_vk_tty.c | 352 ++++ drivers/soc/qcom/mdt_loader.c | 7 +- fs/exec.c | 96 +- include/linux/firmware.h | 8 +- include/linux/fs.h | 20 + include/uapi/linux/misc/bcm_vk.h | 99 ++ lib/test_firmware.c | 144 +- .../selftests/firmware/fw_filesystem.sh | 80 + 22 files changed, 4516 insertions(+), 49 deletions(-) create mode 100644 drivers/misc/bcm-vk/Kconfig create mode 100644 drivers/misc/bcm-vk/Makefile create mode 100644 drivers/misc/bcm-vk/bcm_vk.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_dev.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_legacy.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_tty.c create mode 100644 include/uapi/linux/misc/bcm_vk.h -- 2.17.1

[PATCH net-next v6 0/5] kselftest: add fixture parameters

by Jakub Kicinski

Hi! This set is an attempt to make running tests for different sets of data easier. The direct motivation is the tls test which we'd like to run for TLS 1.2 and TLS 1.3, but currently there is no easy way to invoke the same tests with different parameters. Tested all users of kselftest_harness.h. Dave, would it be possible to take these via net-next? It seems we're failing to get Shuah's attention. v2: - don't run tests by fixture - don't pass params as an explicit argument v3: - go back to the orginal implementation with an extra parameter, and running by fixture (Kees); - add LIST_APPEND helper (Kees); - add a dot between fixture and param name (Kees); - rename the params to variants (Tim); v4: - whitespace fixes. v5 (Kees): - move a comment; - remove a temporary variable; - reword the commit message on patch 4. v6: - resend for net-next. v1: https://lore.kernel.org/netdev/20200313031752.2332565-1-kuba@kernel.org/ v2: https://lore.kernel.org/netdev/20200314005501.2446494-1-kuba@kernel.org/ v3: https://lore.kernel.org/netdev/20200316225647.3129354-1-kuba@kernel.org/ v4: https://lore.kernel.org/netdev/20200317010419.3268916-1-kuba@kernel.org/ v5: https://lore.kernel.org/netdev/20200318010153.40797-1-kuba@kernel.org/ Jakub Kicinski (5): kselftest: factor out list manipulation to a helper kselftest: create fixture objects kselftest: run tests by fixture kselftest: add fixture variants selftests: tls: run all tests for TLS 1.2 and TLS 1.3 Documentation/dev-tools/kselftest.rst | 3 +- tools/testing/selftests/kselftest_harness.h | 234 +++++++++++++++----- tools/testing/selftests/net/tls.c | 93 ++------ 3 files changed, 202 insertions(+), 128 deletions(-) -- 2.25.4

[PATCH] selftests: introduce gen_tar Makefile target

by Veronika Kabatova

The gen_kselftest_tar.sh always packages *all* selftests and doesn't pass along any variables to `make install` to influence what should be built. This can result in an early error on the command line ("Unknown tarball format TARGETS=XXX"), or unexpected test failures as the tarball contains tests people wanted to skip on purpose. Since the makefile already contains all the logic, we can add a target for packaging. Keep the default .gz target the script uses, and actually extend the supported formats by using tar's autodetection. To not break current workflows, keep the gen_kselftest_tar.sh script as it is, with an added suggestion to use the makefile target instead.

[PATCH] selftests: fix kvm relocatable native/cross builds and installs

by Shuah Khan

kvm test Makefile doesn't fully support cross-builds and installs. UNAME_M = $(shell uname -m) variable is used to define the target programs and libraries to be built from arch specific sources in sub-directories. For cross-builds to work, UNAME_M has to map to ARCH and arch specific directories and targets in this Makefile. UNAME_M variable to used to run the compiles pointing to the right arch directories and build the right targets for these supported architectures. TEST_GEN_PROGS and LIBKVM are set using UNAME_M variable. LINUX_TOOL_ARCH_INCLUDE is set using ARCH variable. x86_64 targets are named to include x86_64 as a suffix and directories for includes are in x86_64 sub-directory. s390x and aarch64 follow the same convention. "uname -m" doesn't result in the correct mapping for s390x and aarch64. Fix it to set UNAME_M correctly for s390x and aarch64 cross-builds. In addition, Makefile doesn't create arch sub-directories in the case of relocatable builds and test programs under s390x and x86_64 directories fail to build. This is a problem for native and cross-builds. Fix it to create all necessary directories keying off of TEST_GEN_PROGS. The following use-cases work with this change: Native x86_64: make O=/tmp/kselftest -C tools/testing/selftests TARGETS=kvm install \ INSTALL_PATH=$HOME/x86_64 arm64 cross-build: make O=$HOME/arm64_build/ ARCH=arm64 HOSTCC=gcc \ CROSS_COMPILE=aarch64-linux-gnu- defconfig make O=$HOME/arm64_build/ ARCH=arm64 HOSTCC=gcc \ CROSS_COMPILE=aarch64-linux-gnu- all make kselftest-install TARGETS=kvm O=$HOME/arm64_build ARCH=arm64 \ HOSTCC=gcc CROSS_COMPILE=aarch64-linux-gnu- s390x cross-build: make O=$HOME/s390x_build/ ARCH=s390 HOSTCC=gcc \ CROSS_COMPILE=s390x-linux-gnu- defconfig make O=$HOME/s390x_build/ ARCH=s390 HOSTCC=gcc \ CROSS_COMPILE=s390x-linux-gnu- all make kselftest-install TARGETS=kvm O=$HOME/s390x_build/ ARCH=s390 \ HOSTCC=gcc CROSS_COMPILE=s390x-linux-gnu- all No regressions in the following use-cases: make -C tools/testing/selftests TARGETS=kvm make kselftest-all TARGETS=kvm Signed-off-by: Shuah Khan <skhan(a)linuxfoundation.org> --- tools/testing/selftests/kvm/Makefile | 29 +++++++++++++++++++++++++++- 1 file changed, 28 insertions(+), 1 deletion(-) diff --git a/tools/testing/selftests/kvm/Makefile b/tools/testing/selftests/kvm/Makefile index 712a2ddd2a27..b728c0a0f9b2 100644 --- a/tools/testing/selftests/kvm/Makefile +++ b/tools/testing/selftests/kvm/Makefile @@ -5,8 +5,34 @@ all: top_srcdir = ../../../..

[PATCH] selftests: add build/cross-build dependency check script

by Shuah Khan

Add build/cross-build dependency check script kselftest_deps.sh This script does the following: Usage: ./kselftest_deps.sh -[p] <compiler> [test_name] kselftest_deps.sh [-p] gcc kselftest_deps.sh [-p] gcc vm kselftest_deps.sh [-p] aarch64-linux-gnu-gcc kselftest_deps.sh [-p] aarch64-linux-gnu-gcc vm - Should be run in selftests directory in the kernel repo. - Checks if Kselftests can be built/cross-built on a system. - Parses all test/sub-test Makefile to find library dependencies. - Runs compile test on a trivial C file with LDLIBS specified in the test Makefiles to identify missing library dependencies. - Prints suggested target list for a system filtering out tests failed the build dependency check from the TARGETS in Selftests the main Makefile when optional -p is specified. - Prints pass/fail dependency check for each tests/sub-test. - Prints pass/fail targets and libraries. - Default: runs dependency checks on all tests. - Optional test name can be specified to check dependencies for it. To make LDLIBS parsing easier - change gpio and memfd Makefiles to use the same temporary variable used to find and add libraries to LDLIBS. - simlify LDLIBS append logic in intel_pstate/Makefile.

[PATCH] selftests/ftrace: Check the first record for kprobe_args_type.tc

by Xiao Yang

It is possible to get multiple records from trace during test and then more than 4 arguments are assigned to ARGS. This situation results in the failure of kprobe_args_type.tc. For example: ----------------------------------------------------------- grep testprobe trace ftracetest-5902 [001] d... 111195.682227: testprobe: (_do_fork+0x0/0x460) arg1=334823024 arg2=334823024 arg3=0x13f4fe70 arg4=7 pmlogger-5949 [000] d... 111195.709898: testprobe: (_do_fork+0x0/0x460) arg1=345308784 arg2=345308784 arg3=0x1494fe70 arg4=7 grep testprobe trace sed -e 's/.* arg1=$.*$ arg2=$.*$ arg3=$.*$ arg4=$.*$/\1 \2 \3 \4/' ARGS='334823024 334823024 0x13f4fe70 7 345308784 345308784 0x1494fe70 7' ----------------------------------------------------------- We don't care which process calls do_fork so just check the first record to fix the issue.

[PATCH] selftests/ftrace: Check required filter files before running test

by Xiao Yang

Without CONFIG_DYNAMIC_FTRACE, some tests get failure because required filter files(set_ftrace_filter/available_filter_functions/stack_trace_filter) are missing. So implement check_filter_file() and make all related tests check required filter files by it. BTW: set_ftrace_filter and available_filter_functions are introduced together so just check either of them.

[PATCH v6 0/5] KUnit-KASAN Integration

by David Gow

This patchset contains everything needed to integrate KASAN and KUnit. KUnit will be able to: (1) Fail tests when an unexpected KASAN error occurs (2) Pass tests when an expected KASAN error occurs Convert KASAN tests to KUnit with the exception of copy_user_test because KUnit is unable to test those. Add documentation on how to run the KASAN tests with KUnit and what to expect when running these tests. Depends on "[PATCH v3 kunit-next 0/2] kunit: extend kunit resources API" patchset [1] Changes from v5: - Split out the panic_on_warn changes to a separate patch. - Fix documentation to fewer to the new Kconfig names. - Fix some changes which were in the wrong patch. - Rebase on top of kselftest/kunit (currently identical to 5.7-rc1) Changes from v4: - KASAN no longer will panic on errors if both panic_on_warn and kasan_multishot are enabled. - As a result, the KASAN tests will no-longer disable panic_on_warn. - This also means panic_on_warn no-longer needs to be exported. - The use of temporary "kasan_data" variables has been cleaned up somewhat. - A potential refcount/resource leak should multiple KASAN errors appear during an assertion was fixed. - Some wording changes to the KASAN test Kconfig entries. Changes from v3: - KUNIT_SET_KASAN_DATA and KUNIT_DO_EXPECT_KASAN_FAIL have been combined and included in KUNIT_DO_EXPECT_KASAN_FAIL() instead. - Reordered logic in kasan_update_kunit_status() in report.c to be easier to read. - Added comment to not use the name "kasan_data" for any kunit tests outside of KUNIT_EXPECT_KASAN_FAIL(). Changes since v2: - Due to Alan's changes in [1], KUnit can be built as a module. - The name of the tests that could not be run with KUnit has been changed to be more generic: test_kasan_module. - Documentation on how to run the new KASAN tests and what to expect when running them has been added. - Some variables and functions are now static. - Now save/restore panic_on_warn in a similar way to kasan_multi_shot and renamed the init/exit functions to be more generic to accommodate. - Due to [2] in kasan_strings, kasan_memchr, and kasan_memcmp will fail if CONFIG_AMD_MEM_ENCRYPT is enabled so return early and print message explaining this circumstance. - Changed preprocessor checks to C checks where applicable. Changes since v1: - Make use of Alan Maguire's suggestion to use his patch that allows static resources for integration instead of adding a new attribute to the kunit struct - All KUNIT_EXPECT_KASAN_FAIL statements are local to each test - The definition of KUNIT_EXPECT_KASAN_FAIL is local to the test_kasan.c file since it seems this is the only place this will be used. - Integration relies on KUnit being builtin - copy_user_test has been separated into its own file since KUnit is unable to test these. This can be run as a module just as before, using CONFIG_TEST_KASAN_USER - The addition to the current task has been separated into its own patch as this is a significant enough change to be on its own.

[PATCH bpf 1/2] bpf, x86: Fix encoding for lower 8-bit registers in BPF_STX BPF_B

by Luke Nelson

This patch fixes an encoding bug in emit_stx for BPF_B when the source register is BPF_REG_FP. The current implementation for BPF_STX BPF_B in emit_stx saves one REX byte when the operands can be encoded using Mod-R/M alone. The lower 8 bits of registers %rax, %rbx, %rcx, and %rdx can be accessed without using a REX prefix via %al, %bl, %cl, and %dl, respectively. Other registers, (e.g., %rsi, %rdi, %rbp, %rsp) require a REX prefix to use their 8-bit equivalents (%sil, %dil, %bpl, %spl). The current code checks if the source for BPF_STX BPF_B is BPF_REG_1 or BPF_REG_2 (which map to %rdi and %rsi), in which case it emits the required REX prefix. However, it misses the case when the source is BPF_REG_FP (mapped to %rbp). The result is that BPF_STX BPF_B with BPF_REG_FP as the source operand will read from register %ch instead of the correct %bpl. This patch fixes the problem by fixing and refactoring the check on which registers need the extra REX byte. Since no BPF registers map to %rsp, there is no need to handle %spl.

[PATCH v1] kobject: make sure parent is not released before children

by Brendan Higgins

From: Heikki Krogerus <heikki.krogerus(a)linux.intel.com> Previously, kobjects were released before the associated kobj_types; this can cause a kobject deallocation to fail when the kobject has children; an example of this is in software_node_unregister_nodes(); it calls release on the parent before children meaning that children can be released after the parent, which may be needed for removal. So, take a reference to the parent before we delete a node to ensure that the parent is not released before the children.

[PATCH v9 0/3] mm/hmm/test: add self tests for HMM

by Ralph Campbell

This series adds basic self tests for HMM and are intended for Jason Gunthorpe's rdma tree since I believe he is planning to make some HMM related changes that this can help test. Changes v8 -> v9: Rebased to linux-5.7.0-rc1. Moved include/uapi/linux/test_hmm.h to lib/test_hmm_uapi.h Added calls to release_mem_region() to free device private addresses Applied Jason's suggested changes for v8. Added a check for no VMA read access before migrating to device private memory. Changes v7 -> v8: Rebased to Jason's rdma/hmm tree, plus Jason's 6 patch series "Small hmm_range_fault() cleanups". Applied a number of changes from Jason's comments. Changes v6 -> v7: Rebased to linux-5.6.0-rc6 Reverted back to just using mmu_interval_notifier_insert() and making this series only introduce HMM self tests. Changes v5 -> v6: Rebased to linux-5.5.0-rc6 Refactored mmu interval notifier patches Converted nouveau to use the new mmu interval notifier API Changes v4 -> v5: Added mmu interval notifier insert/remove/update callable from the invalidate() callback Updated HMM tests to use the new core interval notifier API Changes v1 -> v4: https://lore.kernel.org/linux-mm/20191104222141.5173-1-rcampbell@nvidia.com Ralph Campbell (3): mm/hmm/test: add selftest driver for HMM mm/hmm/test: add selftests for HMM MAINTAINERS: add HMM selftests MAINTAINERS | 3 + lib/Kconfig.debug | 13 + lib/Makefile | 1 + lib/test_hmm.c | 1175 ++++++++++++++++++++ lib/test_hmm_uapi.h | 59 + tools/testing/selftests/vm/.gitignore | 1 + tools/testing/selftests/vm/Makefile | 3 + tools/testing/selftests/vm/config | 2 + tools/testing/selftests/vm/hmm-tests.c | 1359 ++++++++++++++++++++++++ tools/testing/selftests/vm/run_vmtests | 16 + tools/testing/selftests/vm/test_hmm.sh | 97 ++ 11 files changed, 2729 insertions(+) create mode 100644 lib/test_hmm.c create mode 100644 lib/test_hmm_uapi.h create mode 100644 tools/testing/selftests/vm/hmm-tests.c create mode 100755 tools/testing/selftests/vm/test_hmm.sh -- 2.25.2

[PATCH v3] selftests/harness: Add support for argc and argv.

by Kuniyuki Iwashima

Currently tests are often written in C and shell script. In many cases, the script passes some arguments to the C program. However, the helper functions do not support arguments, so many tests are written without helper functions. This patch introduces two function macros: ARG_SETUP and ARG_TEARDOWN. The 'argc' and 'argv' are exposed as the member of the 'arg'. We can parse them and populate/cleanup the 'arg->data' in ARG_SETUP/ARG_TEARDOWN. The 'arg' is passed to TEST, TEST_*, and FIXTURE_* so that we can write tests more flexibly with helper functions.

[PATCH v3 0/7] firmware: add partial read support in request_firmware_into_buf

by Scott Branden

This patch series adds partial read support in request_firmware_into_buf. In order to accept the enhanced API it has been requested that kernel selftests and upstreamed driver utilize the API enhancement and so are included in this patch series. Also in this patch series is the addition of a new Broadcom VK driver utilizing the new request_firmware_into_buf enhanced API. Changes from v2: - remove unnecessary code and mutex locks in lib/test_firmware.c - remove VK_IOCTL_ACCESS_BAR support from driver and use pci sysfs instead - remove bitfields - remove Kconfig default m - adjust formatting and some naming based on feedback - fix error handling conditions - use appropriate return codes - use memcpy_toio instead of direct access to PCIE bar - Scott Branden (7): fs: introduce kernel_pread_file* support firmware: add offset to request_firmware_into_buf test_firmware: add partial read support for request_firmware_into_buf firmware: test partial file reads of request_firmware_into_buf bcm-vk: add bcm_vk UAPI misc: bcm-vk: add Broadcom VK driver MAINTAINERS: bcm-vk: add maintainer for Broadcom VK Driver MAINTAINERS | 7 + drivers/base/firmware_loader/firmware.h | 5 + drivers/base/firmware_loader/main.c | 52 +- drivers/misc/Kconfig | 1 + drivers/misc/Makefile | 1 + drivers/misc/bcm-vk/Kconfig | 41 + drivers/misc/bcm-vk/Makefile | 12 + drivers/misc/bcm-vk/bcm_vk.h | 406 +++++ drivers/misc/bcm-vk/bcm_vk_dev.c | 1179 ++++++++++++++ drivers/misc/bcm-vk/bcm_vk_legacy.c | 89 ++ drivers/misc/bcm-vk/bcm_vk_msg.c | 1420 +++++++++++++++++ drivers/misc/bcm-vk/bcm_vk_msg.h | 215 +++ drivers/misc/bcm-vk/bcm_vk_sg.c | 271 ++++ drivers/misc/bcm-vk/bcm_vk_sg.h | 60 + drivers/misc/bcm-vk/bcm_vk_tty.c | 323 ++++ drivers/soc/qcom/mdt_loader.c | 7 +- fs/exec.c | 96 +- include/linux/firmware.h | 8 +- include/linux/fs.h | 20 + include/uapi/linux/misc/bcm_vk.h | 99 ++ lib/test_firmware.c | 144 +- .../selftests/firmware/fw_filesystem.sh | 80 + 22 files changed, 4487 insertions(+), 49 deletions(-) create mode 100644 drivers/misc/bcm-vk/Kconfig create mode 100644 drivers/misc/bcm-vk/Makefile create mode 100644 drivers/misc/bcm-vk/bcm_vk.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_dev.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_legacy.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_tty.c create mode 100644 include/uapi/linux/misc/bcm_vk.h -- 2.17.1

[bug report] kunit: test: add support for test abort

by Dan Carpenter

Hello Brendan Higgins, The patch 5f3e06208920: "kunit: test: add support for test abort" from Sep 23, 2019, leads to the following static checker warning: lib/kunit/try-catch.c:93 kunit_try_catch_run() misplaced newline? ' # %s: Unknown error: %d lib/kunit/try-catch.c 58 void kunit_try_catch_run(struct kunit_try_catch *try_catch, void *context) 59 { 60 DECLARE_COMPLETION_ONSTACK(try_completion); 61 struct kunit *test = try_catch->test; 62 struct task_struct *task_struct; 63 int exit_code, time_remaining; 64 65 try_catch->context = context; 66 try_catch->try_completion = &try_completion; 67 try_catch->try_result = 0; 68 task_struct = kthread_run(kunit_generic_run_threadfn_adapter, 69 try_catch, 70 "kunit_try_catch_thread"); 71 if (IS_ERR(task_struct)) { 72 try_catch->catch(try_catch->context); 73 return; 74 } 75 76 time_remaining = wait_for_completion_timeout(&try_completion, 77 kunit_test_timeout()); 78 if (time_remaining == 0) { 79 kunit_err(test, "try timed out\n"); ^^ The kunit_log() macro adds its own newline. Most of the callers add a newline. It should be the callers add a newline because that's how everything else works in the kernel. The dev_printk() stuff will sometimes add a newline, but never a duplicate newline. In other words, it's slightly complicated. But basically the caller should add a newline. 80 try_catch->try_result = -ETIMEDOUT; 81 } 82 83 exit_code = try_catch->try_result; 84 85 if (!exit_code) 86 return; 87 88 if (exit_code == -EFAULT) 89 try_catch->try_result = 0; 90 else if (exit_code == -EINTR) 91 kunit_err(test, "wake_up_process() was never called\n"); ^^ 92 else if (exit_code) 93 kunit_err(test, "Unknown error: %d\n", exit_code); ^^ 94 95 try_catch->catch(try_catch->context); 96 } regards, dan carpenter

I suggest to improve this change description. * How do you think about a wording variant like the following? Reset the member “test_fs” of the test configuration after a call of the function “kfree_const” to a null pointer so that a double memory release will not be performed. * Would you like to add the tag “Fixes”?

[PATCH AUTOSEL 4.14 12/28] selftests: kmod: fix handling test numbers above 9

by Sasha Levin

[PATCH AUTOSEL 4.19 44/47] tracing/selftests: Turn off timeout setting

by Sasha Levin

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> [ Upstream commit b43e78f65b1d35fd3e13c7b23f9b64ea83c9ad3a ] As the ftrace selftests can run for a long period of time, disable the timeout that the general selftests have. If a selftest hangs, then it probably means the machine will hang too.

[PATCH 0/1] selftests: kvm: Overlapped memory regions test

by Wainer dos Santos Moschetta

This introduces a test case to check memory slots with overlapped regions on the guest address cannot be added. The cases checked are described in the block comment upon test_overlap_memory_regions() (see the patch 01). I didn't see the need to calcute the addresses on compile/run-time, so I just left them hard-coded (remember: aligned 1M to work on s390x). It works on x86_64, aarch64, and s390x. The patch is based on queue branch. Ah, I did some cosmetic changes on test_add_max_memory_regions() too. If it is not OK to be in a single patch...let me know.

[PATCH v16 00/10] Landlock LSM

by Mickaël Salaün

Hi, This new patch series brings some improvements while simplifying the code, fixes some bugs and adds more tests: Use a bitfield of layers to properly manage superset and subset of access rights, whatever their order in the stack of layers [1]. Allow to open pipes and similar special files through /proc/self/fd, as well as internal filesystems such as nsfs through /proc/self/ns, because disconnected path cannot be evaluated. Such special filesystems could be handled with a future evolution. For the sake of simplicity, forbid reparenting when linking or renaming to protect against possible privilege escalation. This could happen by changing the hierarchy of a file or directory in relation to an enforced access policy (from the set of layers). This will be relaxed in the future with more complex code. Rename the unlink and rmdir access rights to a more generic ones: remove_dir and remove_file. Indeed it makes sense to also use them for the action of renaming a file or a directory, which may lead to the removal of the source file or directory. Replace the link_to, rename_from and rename_to access rights with remove_file, remove_dir and make_* . Add multiple tests to check semantic, and improve test coverage for security/landlock to 94.1% of lines (best possible with deterministic user space tests). Add current limitations to documentation: file renaming and linking, OverlayFS and special filesystems (e.g. nsfs). The previously identified memory accounting limitation can already be solved with the (kernel) Memory Resource Controller from cgroup. The SLOC count is 1267 for security/landlock/ and 1643 for tools/testing/selftest/landlock/ . The compiled documentation is available here: https://landlock.io/linux-doc/landlock-v16/security/landlock/index.html This series can be applied on top of v5.7-rc1. This can be tested with CONFIG_SECURITY_LANDLOCK and CONFIG_SAMPLE_LANDLOCK. This patch series can be found in a Git repository here: https://github.com/landlock-lsm/linux/commits/landlock-v16 I would really appreciate constructive comments on this patch series. # Landlock LSM The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Because Landlock is a stackable LSM [2], it makes possible to create safe security sandboxes as new security layers in addition to the existing system-wide access-controls. This kind of sandbox is expected to help mitigate the security impact of bugs or unexpected/malicious behaviors in user-space applications. Landlock empowers any process, including unprivileged ones, to securely restrict themselves. Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic. Landlock also takes inspiration from other OS sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD Pledge/Unveil.

[PATCH v5 0/4] KUnit-KASAN Integration

by David Gow

This patchset contains everything needed to integrate KASAN and KUnit. KUnit will be able to: (1) Fail tests when an unexpected KASAN error occurs (2) Pass tests when an expected KASAN error occurs Convert KASAN tests to KUnit with the exception of copy_user_test because KUnit is unable to test those. Add documentation on how to run the KASAN tests with KUnit and what to expect when running these tests. Depends on "[PATCH v3 kunit-next 0/2] kunit: extend kunit resources API" patchset [1] Changes from v4: - KASAN no longer will panic on errors if both panic_on_warn and kasan_multishot are enabled. - As a result, the KASAN tests will no-longer disable panic_on_warn. - This also means panic_on_warn no-longer needs to be exported. - The use of temporary "kasan_data" variables has been cleaned up somewhat. - A potential refcount/resource leak should multiple KASAN errors appear during an assertion was fixed. - Some wording changes to the KASAN test Kconfig entries. Changes from v3: - KUNIT_SET_KASAN_DATA and KUNIT_DO_EXPECT_KASAN_FAIL have been combined and included in KUNIT_DO_EXPECT_KASAN_FAIL() instead. - Reordered logic in kasan_update_kunit_status() in report.c to be easier to read. - Added comment to not use the name "kasan_data" for any kunit tests outside of KUNIT_EXPECT_KASAN_FAIL(). Changes since v2: - Due to Alan's changes in [1], KUnit can be built as a module. - The name of the tests that could not be run with KUnit has been changed to be more generic: test_kasan_module. - Documentation on how to run the new KASAN tests and what to expect when running them has been added. - Some variables and functions are now static. - Now save/restore panic_on_warn in a similar way to kasan_multi_shot and renamed the init/exit functions to be more generic to accommodate. - Due to [2] in kasan_strings, kasan_memchr, and kasan_memcmp will fail if CONFIG_AMD_MEM_ENCRYPT is enabled so return early and print message explaining this circumstance. - Changed preprocessor checks to C checks where applicable. Changes since v1: - Make use of Alan Maguire's suggestion to use his patch that allows static resources for integration instead of adding a new attribute to the kunit struct - All KUNIT_EXPECT_KASAN_FAIL statements are local to each test - The definition of KUNIT_EXPECT_KASAN_FAIL is local to the test_kasan.c file since it seems this is the only place this will be used. - Integration relies on KUnit being builtin - copy_user_test has been separated into its own file since KUnit is unable to test these. This can be run as a module just as before, using CONFIG_TEST_KASAN_USER - The addition to the current task has been separated into its own patch as this is a significant enough change to be on its own.

This series adds basic self tests for HMM and are intended for Jason Gunthorpe's rdma tree which has a number of HMM patches applied. Changes v7 -> v8: Rebased to Jason's rdma/hmm tree, plus Jason's 6 patch series "Small hmm_range_fault() cleanups". Applied a number of changes from Jason's comments. Changes v6 -> v7: Rebased to linux-5.6.0-rc6 Reverted back to just using mmu_interval_notifier_insert() and making this series only introduce HMM self tests. Changes v5 -> v6: Rebased to linux-5.5.0-rc6 Refactored mmu interval notifier patches Converted nouveau to use the new mmu interval notifier API Changes v4 -> v5: Added mmu interval notifier insert/remove/update callable from the invalidate() callback Updated HMM tests to use the new core interval notifier API Changes v1 -> v4: https://lore.kernel.org/linux-mm/20191104222141.5173-1-rcampbell@nvidia.com Ralph Campbell (3): mm/hmm/test: add selftest driver for HMM mm/hmm/test: add selftests for HMM MAINTAINERS: add HMM selftests MAINTAINERS | 3 + include/uapi/linux/test_hmm.h | 59 ++ lib/Kconfig.debug | 12 + lib/Makefile | 1 + lib/test_hmm.c | 1177 +++++++++++++++++++++ tools/testing/selftests/vm/.gitignore | 1 + tools/testing/selftests/vm/Makefile | 3 + tools/testing/selftests/vm/config | 2 + tools/testing/selftests/vm/hmm-tests.c | 1353 ++++++++++++++++++++++++ tools/testing/selftests/vm/run_vmtests | 16 + tools/testing/selftests/vm/test_hmm.sh | 97 ++ 11 files changed, 2724 insertions(+) create mode 100644 include/uapi/linux/test_hmm.h create mode 100644 lib/test_hmm.c create mode 100644 tools/testing/selftests/vm/hmm-tests.c create mode 100755 tools/testing/selftests/vm/test_hmm.sh -- 2.20.1

[PATCH v8 kunit-next 0/4] kunit: add debugfs representation to show results

by Alan Maguire

When kunit tests are run on native (i.e. non-UML) environments, the results of test execution are often intermixed with dmesg output. This patch series attempts to solve this by providing a debugfs representation of the results of the last test run, available as /sys/kernel/debug/kunit/<testsuite>/results Changes since v7: - renamed KUNIT_INDENT[2] to KUNIT_SUBTEST_INDENT, KUNIT_SUBSUBTEST_INDENT and added more description to their definitions to clarify why they are defined as they are (Shuah) - defined KUNIT_SUBSUBTEST_INDENT directly as 8 spaces to avoid checkpatch error (Shuah) Changes since v6: - fixed regexp parsing in kunit_parser.py to ensure test results are read successfully with 4-space indentation (Brendan, patch 3) Changes since v5: - replaced undefined behaviour use of snprintf(buf, ..., buf) in kunit_log() with a function to append string to existing log (Frank, patch 1) - added clarification on log size limitations to documentation (Frank, patch 4) Changes since v4: - added suite-level log expectations to kunit log test (Brendan, patch 2) - added log expectations (of it being NULL) for case where CONFIG_KUNIT_DEBUGFS=n to kunit log test (patch 2) - added patch 3 which replaces subtest tab indentation with 4 space indentation as per TAP 14 spec (Frank, patch 3) Changes since v3: - added CONFIG_KUNIT_DEBUGFS to support conditional compilation of debugfs representation, including string logging (Frank, patch 1) - removed unneeded NULL check for test_case in kunit_suite_for_each_test_case() (Frank, patch 1) - added kunit log test to verify logging multiple strings works (Frank, patch 2) - rephrased description of results file (Frank, patch 3) Changes since v2: - updated kunit_status2str() to kunit_status_to_string() and made it static inline in include/kunit/test.h (Brendan) - added log string to struct kunit_suite and kunit_case, with log pointer in struct kunit pointing at the case log. This allows us to collect kunit_[err|info|warning]() messages at the same time as we printk() them. This solves for the most part the sharing of log messages between test execution and debugfs since we just print the suite log (which contains the test suite preamble) and the individual test logs. The only exception is the suite-level status, which we cannot store in the suite log as it would mean we'd print the suite and its status prior to the suite's results. (Brendan, patch 1) - dropped debugfs-based kunit run patch for now so as not to cause problems with tests currently under development (Brendan) - fixed doc issues with code block (Brendan, patch 3) Changes since v1: - trimmed unneeded include files in lib/kunit/debugfs.c (Greg) - renamed global debugfs functions to be prefixed with kunit_ (Greg) - removed error checking for debugfs operations (Greg) Alan Maguire (4): kunit: add debugfs /sys/kernel/debug/kunit/<suite>/results display kunit: add log test kunit: subtests should be indented 4 spaces according to TAP kunit: update documentation to describe debugfs representation Documentation/dev-tools/kunit/usage.rst | 14 +++ include/kunit/test.h | 63 ++++++++++++-- lib/kunit/Kconfig | 8 ++ lib/kunit/Makefile | 4 + lib/kunit/assert.c | 79 ++++++++--------- lib/kunit/debugfs.c | 116 +++++++++++++++++++++++++ lib/kunit/debugfs.h | 30 +++++++ lib/kunit/kunit-test.c | 44 +++++++++- lib/kunit/test.c | 148 +++++++++++++++++++++++++------- tools/testing/kunit/kunit_parser.py | 10 +-- 10 files changed, 430 insertions(+), 86 deletions(-) create mode 100644 lib/kunit/debugfs.c create mode 100644 lib/kunit/debugfs.h -- 1.8.3.1

[PATCH v5 0/5] kselftest: add fixture parameters

by Jakub Kicinski

Hi! Shuah please consider applying to the kselftest tree. This set is an attempt to make running tests for different sets of data easier. The direct motivation is the tls test which we'd like to run for TLS 1.2 and TLS 1.3, but currently there is no easy way to invoke the same tests with different parameters. Tested all users of kselftest_harness.h. v2: - don't run tests by fixture - don't pass params as an explicit argument v3: - go back to the orginal implementation with an extra parameter, and running by fixture (Kees); - add LIST_APPEND helper (Kees); - add a dot between fixture and param name (Kees); - rename the params to variants (Tim); v4: - whitespace fixes. v5 (Kees): - move a comment; - remove a temporary variable; - reword the commit message on patch 4. v1: https://lore.kernel.org/netdev/20200313031752.2332565-1-kuba@kernel.org/ v2: https://lore.kernel.org/netdev/20200314005501.2446494-1-kuba@kernel.org/ v3: https://lore.kernel.org/netdev/20200316225647.3129354-1-kuba@kernel.org/ v4: https://lore.kernel.org/netdev/20200317010419.3268916-1-kuba@kernel.org/ Jakub Kicinski (5): kselftest: factor out list manipulation to a helper kselftest: create fixture objects kselftest: run tests by fixture kselftest: add fixture variants selftests: tls: run all tests for TLS 1.2 and TLS 1.3 Documentation/dev-tools/kselftest.rst | 3 +- tools/testing/selftests/kselftest_harness.h | 234 +++++++++++++++----- tools/testing/selftests/net/tls.c | 93 ++------ 3 files changed, 202 insertions(+), 128 deletions(-) -- 2.25.1

[RFC v1] software: node: test: add test to exercise parent child add/remove

by Brendan Higgins

Add test which adds a tree of software_nodes, checks that the nodes exist, and then removes the tree. This exercises a bug reported by Naresh Kamboju <naresh.kamboju(a)linaro.org>, and pretty much just takes a test case from the test_printf Kselftest module and refocusses it on adding and then removing a tree of software_nodes. Signed-off-by: Brendan Higgins <brendanhiggins(a)google.com> --- I am not sure if this should be rolled into the property entry test, or should be moved somewhere else; nevertheless, testing the software node API seems like a good idea and this seems like a good place to start. --- drivers/base/test/Kconfig | 14 ++++++++ drivers/base/test/Makefile | 2 ++ drivers/base/test/software-node-test.c | 46 ++++++++++++++++++++++++++ 3 files changed, 62 insertions(+) create mode 100644 drivers/base/test/software-node-test.c diff --git a/drivers/base/test/Kconfig b/drivers/base/test/Kconfig index 305c7751184a..b42f385fe233 100644 --- a/drivers/base/test/Kconfig +++ b/drivers/base/test/Kconfig @@ -11,3 +11,17 @@ config TEST_ASYNC_DRIVER_PROBE config KUNIT_DRIVER_PE_TEST bool "KUnit Tests for property entry API" depends on KUNIT=y +config KUNIT_DRIVER_SOFTWARE_NODE_TEST + bool "KUnit Tests for software node API" + depends on KUNIT=y + help + This builds the software node API tests. + + KUnit tests run during boot and output the results to the debug log + in TAP format (http://testanything.org/).

[PATCH] selftest: add a script to perform selftest compile tests

by Tim Bird

From: Tim Bird <tim.bird(a)sony.com> Add ksft-compile-test.sh. This is a program used to test cross-compilation and installation of selftest tests. See the test usage for help This program currently tests 3 scenarios out of a larger matrix of possibly interesting scenarios. For each scenario, it conducts multiple tests for correctness. This version tests: 1) does the test compile 2) is the kernel source directory clean after the compile 3) does the test install operation succeed 4) does the test run script reference the test Signed-off-by: Tim Bird <tim.bird(a)sony.com> --- MAINTAINERS | 6 + tools/testing/selftests/ksft-compile-test.sh | 567 +++++++++++++++++++++++++++ 2 files changed, 573 insertions(+) create mode 100755 tools/testing/selftests/ksft-compile-test.sh diff --git a/MAINTAINERS b/MAINTAINERS index cc1d18c..a6289c7 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -9127,6 +9127,12 @@ S: Maintained F: tools/testing/selftests/ F: Documentation/dev-tools/kselftest* +KERNEL SELFTEST SELFTEST +M: Tim Bird <tim.bird(a)sony.com> +L: linux-kselftest(a)vger.kernel.org +S: Maintained +F: tools/testing/selftests/ksft-compile-test.sh + KERNEL UNIT TESTING FRAMEWORK (KUnit) M: Brendan Higgins <brendanhiggins(a)google.com> L: linux-kselftest(a)vger.kernel.org diff --git a/tools/testing/selftests/ksft-compile-test.sh b/tools/testing/selftests/ksft-compile-test.sh new file mode 100755 index 0000000..e36e858 --- /dev/null +++ b/tools/testing/selftests/ksft-compile-test.sh @@ -0,0 +1,567 @@ +#!/bin/bash +# SPDX-License-Identifier: GPL-2.0-only OR MIT +# +# ksft-compile-test.sh - test compiling Linux kernel selftests under lots of +# different configurations.

[PATCH] selftests/tpm2: Change exception handling to be Python 3 compatible

by Jarkko Sakkinen

I need more time to fix all the byte array / string related stuff but it makes sense to fix the exceptions as it is fairly mechanical procedure: 1,$s/except $.*$, $.*$:/except \1(\2):/g I.e. fix the low hanging fruit first and the rest later.

[PATCH v5 0/2] selftests: kvm: Introduce the mem_slot_test test

by Wainer dos Santos Moschetta

This series introduces a new KVM selftest (mem_slot_test) that goal is to verify memory slots can be added up to the maximum allowed. An extra slot is attempted which should occur on error. The patch 01 is needed so that the VM fd can be accessed from the test code (for the ioctl call attempting to add an extra slot). I ran the test successfully on x86_64, aarch64, and s390x. This is why it is enabled to build on those arches. - Changelog - v4 -> v5: - Initialize the guest_addr and mem_reg_size variables on definition [krish.sadhukhan] v3 -> v4: - Discarded mem_reg_flags variable. Simply using 0 instead [drjones] - Discarded kvm_region pointer. Instead passing a compound literal in the ioctl [drjones] - All variables are declared on the declaration block [drjones] v2 -> v3: - Keep alphabetical order of .gitignore and Makefile [drjones] - Use memory region flags equals to zero [drjones] - Changed mmap() assert from 'mem != NULL' to 'mem != MAP_FAILED' [drjones] - kvm_region is declared along side other variables and malloc()'ed later [drjones] - Combined two asserts into a single 'ret == -1 && errno == EINVAL' [drjones] v1 -> v2: - Rebased to queue - vm_get_fd() returns int instead of unsigned int (patch 01) [drjones] - Removed MEM_REG_FLAGS and GUEST_VM_MODE defines [drjones] - Replaced DEBUG() with pr_info() [drjones] - Calculate number of guest pages with vm_calc_num_guest_pages() [drjones] - Using memory region of 1 MB sized (matches mininum needed for s390x) - Removed the increment of guest_addr after the loop [drjones] - Added assert for the errno when adding a slot beyond-the-limit [drjones] - Prefer KVM_MEM_READONLY flag but on s390x it switch to KVM_MEM_LOG_DIRTY_PAGES, so ensure the coverage of both flags. Also somewhat tests the KVM_CAP_READONLY_MEM capability check [drjones] - Moved the test logic to test_add_max_slots(), this allows to more easily add new cases in the "suite". v1: https://lore.kernel.org/kvm/20200330204310.21736-1-wainersm@redhat.com Wainer dos Santos Moschetta (2): selftests: kvm: Add vm_get_fd() in kvm_util selftests: kvm: Add mem_slot_test test tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 3 + .../testing/selftests/kvm/include/kvm_util.h | 1 + tools/testing/selftests/kvm/lib/kvm_util.c | 5 ++ tools/testing/selftests/kvm/mem_slot_test.c | 69 +++++++++++++++++++ 5 files changed, 79 insertions(+) create mode 100644 tools/testing/selftests/kvm/mem_slot_test.c -- 2.17.2

[PATCH] tracing: Fix the race between registering 'snapshot' event trigger and triggering 'snapshot' operation

by Xiao Yang

Traced event can trigger 'snapshot' operation(i.e. calls snapshot_trigger() or snapshot_count_trigger()) when register_snapshot_trigger() has completed registration but doesn't allocate spare buffer for 'snapshot' event trigger.

[PATCH] selftests/ipc: Fix test failure seen after initial test run

by Tyler Hicks

After successfully running the IPC msgque test once, subsequent runs result in a test failure: $ sudo ./run_kselftest.sh TAP version 13 1..1 # selftests: ipc: msgque # Failed to get stats for IPC queue with id 0 # Failed to dump queue: -22 # Bail out! # # Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0 not ok 1 selftests: ipc: msgque # exit=1 The dump_queue() function loops through the possible message queue index values using calls to msgctl(kern_id, MSG_STAT, ...) where kern_id represents the index value. The first time the test is ran, the initial index value of 0 is valid and the test is able to complete. The index value of 0 is not valid in subsequent test runs and the loop attempts to try index values of 1, 2, 3, and so on until a valid index value is found that corresponds to the message queue created earlier in the test. The msgctl() syscall returns -1 and sets errno to EINVAL when invalid index values are used. The test failure is caused by incorrectly comparing errno to -EINVAL when cycling through possible index values. Fix invalid test failures on subsequent runs of the msgque test by correctly comparing errno values to a non-negated EINVAL.

[PATCH v3] Documentation: test.h - fix warnings

by Lothar Rubusch

Fix warnings at 'make htmldocs', and formatting issues in the resulting documentation. - test.h: Fix some typos in kernel-doc parameter description. - Documentation/*.rst: Fixing formatting issues, and a duplicate label issue, since using sphinx.ext.autosectionlabel in conf.py, referes to headers are generated automatically and sphinx will not complain about identical headers among documents anymore. The downside is, automatically generated header labels within one document now cannot be overwritten manually anymore. Thus duplicate headers within one document have to have different wording, i.e. this patch modifies some headers. - Documentation/api/*: Flipping over to a page "API" containing a single link to another page "API" seems like a formatting issue. The patch removes one level of indirection. v2: Several documentation fixes v3: Do not touch API documentation index Signed-off-by: Lothar Rubusch <l.rubusch(a)gmail.com> --- Documentation/dev-tools/kunit/start.rst | 13 ++++++++----- Documentation/dev-tools/kunit/usage.rst | 4 ++-- include/kunit/test.h | 7 ++++--- 3 files changed, 14 insertions(+), 10 deletions(-) diff --git a/Documentation/dev-tools/kunit/start.rst b/Documentation/dev-tools/kunit/start.rst index e1c5ce80ce12..bb112cf70624 100644 --- a/Documentation/dev-tools/kunit/start.rst +++ b/Documentation/dev-tools/kunit/start.rst @@ -32,15 +32,17 @@ test targets as well.

i386: selftests: vm: compaction_test: BUG: kernel NULL pointer dereference, address: 00000000

[PATCH] selftests/seccomp: allow clock_nanosleep instead of nanosleep

by Thadeu Lima de Souza Cascardo

glibc 2.31 calls clock_nanosleep when its nanosleep function is used. So the restart_syscall fails after that. In order to deal with it, we trace clock_nanosleep and nanosleep. Then we check for either. This works just fine on systems with both glibc 2.30 and glibc 2.31, whereas it failed before on a system with glibc 2.31.

[PATCH] kselftest/runner: allow to properly deliver signals to tests

by Andrea Righi

While running seccomp_bpf, kill_after_ptrace() gets stuck if we run it via /usr/bin/timeout (that is the default), until the timeout expires. This is because /usr/bin/timeout is preventing to properly deliver signals to ptrace'd children (SIGSYS in this case). This problem can be easily reproduced by running: $ sudo make TARGETS=seccomp kselftest ... # [ RUN ] TRACE_syscall.skip_a# not ok 1 selftests: seccomp: seccomp_bpf # TIMEOUT The test is hanging at this point until the timeout expires and then it reports the timeout error. Prevent this problem by passing --foreground to /usr/bin/timeout, allowing to properly deliver signals to children processes.

[PATCH v2] Documentation: test.h - fix warnings

by Lothar Rubusch

Fix warnings at 'make htmldocs', and formatting issues in the resulting documentation. - test.h: Fix some typos in kernel-doc parameter description. - Documentation/*.rst: Fixing formatting issues, and a duplicate label issue, since using sphinx.ext.autosectionlabel in conf.py, referes to headers are generated automatically and sphinx will not complain about identical headers among documents anymore. The downside is, automatically generated header labels within one document now cannot be overwritten manually anymore. Thus duplicate headers within one document have to have different wording, i.e. this patch modifies some headers. - Documentation/api/*: Flipping over to a page "API" containing a single link to another page "API" seems like a formatting issue. The patch removes one level of indirection.

[PATCH v1] kunit: relax regex for .config entries to allow spaces

by Brendan Higgins

From: Daniel Latypov <dlatypov(a)google.com> kunit parses .config in the `build_reconfig()` of `run_tests()`. Problematically, the current regex '^CONFIG_\w+=\S+$' does not allow for spaces anywhere after the "=", even the option is a string. So kunit will refuse to run if the existing .config has something like CONFIG_CMDLINE="something and_something_else" even if kunit.py will drop this entry when it regenerates the .config! So relax the regex to allow entries that match `CONFIG_\w+=".*"` as a minimal change. The question remains as to whether we should do any validation of the string after the "=", however.

[PATCH v4 0/2] selftests: kvm: Introduce the mem_slot_test test

by Wainer dos Santos Moschetta

This series introduces a new KVM selftest (mem_slot_test) that goal is to verify memory slots can be added up to the maximum allowed. An extra slot is attempted which should occur on error. The patch 01 is needed so that the VM fd can be accessed from the test code (for the ioctl call attempting to add an extra slot). I ran the test successfully on x86_64, aarch64, and s390x. This is why it is enabled to build on those arches. - Changelog - v3 -> v4: - Discarded mem_reg_flags variable. Simply using 0 instead [drjones] - Discarded kvm_region pointer. Instead passing a compound literal in the ioctl [drjones] - All variables are declared on the declaration block [drjones] v2 -> v3: - Keep alphabetical order of .gitignore and Makefile [drjones] - Use memory region flags equals to zero [drjones] - Changed mmap() assert from 'mem != NULL' to 'mem != MAP_FAILED' [drjones] - kvm_region is declared along side other variables and malloc()'ed later [drjones] - Combined two asserts into a single 'ret == -1 && errno == EINVAL' [drjones] v1 -> v2: - Rebased to queue - vm_get_fd() returns int instead of unsigned int (patch 01) [drjones] - Removed MEM_REG_FLAGS and GUEST_VM_MODE defines [drjones] - Replaced DEBUG() with pr_info() [drjones] - Calculate number of guest pages with vm_calc_num_guest_pages() [drjones] - Using memory region of 1 MB sized (matches mininum needed for s390x) - Removed the increment of guest_addr after the loop [drjones] - Added assert for the errno when adding a slot beyond-the-limit [drjones] - Prefer KVM_MEM_READONLY flag but on s390x it switch to KVM_MEM_LOG_DIRTY_PAGES, so ensure the coverage of both flags. Also somewhat tests the KVM_CAP_READONLY_MEM capability check [drjones] - Moved the test logic to test_add_max_slots(), this allows to more easily add new cases in the "suite". v1: https://lore.kernel.org/kvm/20200330204310.21736-1-wainersm@redhat.com Wainer dos Santos Moschetta (2): selftests: kvm: Add vm_get_fd() in kvm_util selftests: kvm: Add mem_slot_test test tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 3 + .../testing/selftests/kvm/include/kvm_util.h | 1 + tools/testing/selftests/kvm/lib/kvm_util.c | 5 ++ tools/testing/selftests/kvm/mem_slot_test.c | 76 +++++++++++++++++++ 5 files changed, 86 insertions(+) create mode 100644 tools/testing/selftests/kvm/mem_slot_test.c -- 2.17.2

[PATCH] kselftest/runner: avoid using timeout when timeout is disabled

by Andrea Righi

Avoid using /usr/bin/timeout unnecessarily if timeout is set to 0 (disabled) in the "settings" file for a specific test. NOTE: without this change (and adding timeout=0 in the corresponding settings file - tools/testing/selftests/seccomp/settings) the seccomp_bpf selftest is always failing with a timeout event during the syscall_restart step.

[PATCH v3 0/2] selftests: kvm: Introduce the mem_slot_test test

by Wainer dos Santos Moschetta

This series introduces a new KVM selftest (mem_slot_test) that goal is to verify memory slots can be added up to the maximum allowed. An extra slot is attempted which should occur on error. The patch 01 is needed so that the VM fd can be accessed from the test code (for the ioctl call attempting to add an extra slot). I ran the test successfully on x86_64, aarch64, and s390x. This is why it is enabled to build on those arches. - Changelog - v2 -> v3: - Keep alphabetical order of .gitignore and Makefile [drjones] - Use memory region flags equals to zero [drjones] - Changed mmap() assert from 'mem != NULL' to 'mem != MAP_FAILED' [drjones] - kvm_region is declared along side other variables and malloc()'ed later [drjones] - Combined two asserts into a single 'ret == -1 && errno == EINVAL' [drjones] v1 -> v2: - Rebased to queue - vm_get_fd() returns int instead of unsigned int (patch 01) [drjones] - Removed MEM_REG_FLAGS and GUEST_VM_MODE defines [drjones] - Replaced DEBUG() with pr_info() [drjones] - Calculate number of guest pages with vm_calc_num_guest_pages() [drjones] - Using memory region of 1 MB sized (matches mininum needed for s390x) - Removed the increment of guest_addr after the loop [drjones] - Added assert for the errno when adding a slot beyond-the-limit [drjones] - Prefer KVM_MEM_READONLY flag but on s390x it switch to KVM_MEM_LOG_DIRTY_PAGES, so ensure the coverage of both flags. Also somewhat tests the KVM_CAP_READONLY_MEM capability check [drjones] - Moved the test logic to test_add_max_slots(), this allows to more easily add new cases in the "suite". v1: https://lore.kernel.org/kvm/20200330204310.21736-1-wainersm@redhat.com Wainer dos Santos Moschetta (2): selftests: kvm: Add vm_get_fd() in kvm_util selftests: kvm: Add mem_slot_test test tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 3 + .../testing/selftests/kvm/include/kvm_util.h | 1 + tools/testing/selftests/kvm/lib/kvm_util.c | 5 ++ tools/testing/selftests/kvm/mem_slot_test.c | 85 +++++++++++++++++++ 5 files changed, 95 insertions(+) create mode 100644 tools/testing/selftests/kvm/mem_slot_test.c -- 2.17.2

[PATCH v3, RESEND] kunit: Fix kunit.py run --build_dir='<foo>' fails on "unclean" trees

by Vitor Massaru Iha

Fix this bug: https://bugzilla.kernel.org/show_bug.cgi?id=205219 For some reason, the environment variable ARCH is used instead of ARCH passed as an argument, this patch uses a copy of the env, but using ARCH=um and CROSS_COMPILER='' to avoid this problem.

[PATCH v2 0/2] selftests: kvm: Introduce the mem_slot_test test

by Wainer dos Santos Moschetta

This series introduces a new KVM selftest (mem_slot_test) that goal is to verify memory slots can be added up to the maximum allowed. An extra slot is attempted which should occur on error. The patch 01 is needed so that the VM fd can be accessed from the test code (for the ioctl call attempting to add an extra slot). I ran the test successfully on x86_64, aarch64, and s390x. This is why it is enabled to build on those arches. v1: https://lore.kernel.org/kvm/20200330204310.21736-1-wainersm@redhat.com Changes v1 -> v2: - Rebased to queue - vm_get_fd() returns int instead of unsigned int (patch 01) [drjones] - Removed MEM_REG_FLAGS and GUEST_VM_MODE defines [drjones] - Replaced DEBUG() with pr_info() [drjones] - Calculate number of guest pages with vm_calc_num_guest_pages() [drjones] - Using memory region of 1 MB sized (matches mininum needed for s390x) - Removed the increment of guest_addr after the loop [drjones] - Added assert for the errno when adding a slot beyond-the-limit [drjones] - Prefer KVM_MEM_READONLY flag but on s390x it switch to KVM_MEM_LOG_DIRTY_PAGES, so ensure the coverage of both flags. Also somewhat tests the KVM_CAP_READONLY_MEM capability check [drjones] - Moved the test logic to test_add_max_slots(), this allows to more easily add new cases in the "suite".

[PATCH AUTOSEL 5.4 22/32] selftests/net: add definition for SOL_DCCP to fix compilation errors for old libc

by Sasha Levin

From: Alan Maguire <alan.maguire(a)oracle.com> [ Upstream commit 83a9b6f639e9f6b632337f9776de17d51d969c77 ] Many systems build/test up-to-date kernels with older libcs, and an older glibc (2.17) lacks the definition of SOL_DCCP in /usr/include/bits/socket.h (it was added in the 4.6 timeframe). Adding the definition to the test program avoids a compilation failure that gets in the way of building tools/testing/selftests/net. The test itself will work once the definition is added; either skipping due to DCCP not being configured in the kernel under test or passing, so there are no other more up-to-date glibc dependencies here it seems beyond that missing definition.

[PATCH v4 0/4] KUnit-KASAN Integration

by Patricia Alfonso

This patchset contains everything needed to integrate KASAN and KUnit. KUnit will be able to: (1) Fail tests when an unexpected KASAN error occurs (2) Pass tests when an expected KASAN error occurs Convert KASAN tests to KUnit with the exception of copy_user_test because KUnit is unable to test those. Add documentation on how to run the KASAN tests with KUnit and what to expect when running these tests. Depends on "[PATCH v3 kunit-next 0/2] kunit: extend kunit resources API" patchset [1] [1] https://lore.kernel.org/linux-kselftest/1585313122-26441-1-git-send-email-a… Changes from v3: - KUNIT_SET_KASAN_DATA and KUNIT_DO_EXPECT_KASAN_FAIL have been combined and included in KUNIT_DO_EXPECT_KASAN_FAIL() instead. - Reordered logic in kasan_update_kunit_status() in report.c to be easier to read. - Added comment to not use the name "kasan_data" for any kunit tests outside of KUNIT_EXPECT_KASAN_FAIL().
