Subject: [PATCH] s390/pci_mmio: fully validate the VMA before calling
follow_pte()
We should not walk/touch page tables outside of VMA boundaries when
holding only the mmap sem in read mode. Evil user space can modify the
VMA layout just before this function runs and e.g., trigger races with
page table removal code since commit dd2283f2605e ("mm: mmap: zap pages
with read mmap_sem in munmap").
find_vma() does not check if the address is >= the VMA start address;
use vma_lookup() instead.

Hi Greg,
We recently hit a hung task timeout issue in synchronize_rcu_expedited on 4.14 branch.
The issue seems to be identical to the one described in `fd6bc19d7676 rcu: Fix missed wakeup of exp_wq waiters`
Can we backport it to 4.14 and 4.19 branch?
The patch doesn't apply cleanly, but it should be trivial to resolve, just do this
- wake_up_all(&rnp->exp_wq[rcu_seq_ctr(rsp->expedited_sequence) & 0x3]);
+ wake_up_all(&rnp->exp_wq[rcu_seq_ctr(s) & 0x3]);
I don't know if we should do it for 4.9, because the handling of sequence number is a bit different.
Thanks,
David

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.
Targeted tests
--------------
Test runs for patches always include a set of base tests, plus some
tests chosen based on the file paths modified by the patch. The latter
are called "targeted tests". If no targeted tests are run, that means
no patch-specific tests are available. Please, consider contributing a
targeted test for related patches to increase test coverage. See
https://docs.engineering.redhat.com/x/_wEZB for more details.

[ Upstream commit 08dad2f4d541fcfe5e7bfda72cc6314bbfd2802f ]
The Synopsys Ethernet IP uses the CSR clock as a base clock for MDC.
The divisor used is set in the MAC_MDIO_Address register field CR
(Clock Rate)
The divisor is there to change the CSR clock into a clock that falls
below the IEEE 802.3 specified max frequency of 2.5MHz.
If the CSR clock is 300MHz, the code falls back to using the reset
value in the MAC_MDIO_Address register, as described in the comment
above this code.
However, 300MHz is actually an allowed value and the proper divider
can be estimated quite easily (it's just 1Hz difference!)
A CSR frequency of 300MHz with the maximum clock rate value of 0x5
(STMMAC_CSR_250_300M, a divisor of 124) gives somewhere around
~2.42MHz which is below the IEEE 802.3 specified maximum.
For the ARTPEC-8 SoC, the CSR clock is this problematic 300MHz,
and unfortunately, the reset-value of the MAC_MDIO_Address CR field
is 0x0.
This leads to a clock rate of zero and a divisor of 42, and gives an
MDC frequency of ~7.14MHz.
Allow CSR clock of 300MHz by making the comparison inclusive.

commit 9801ca279ad37f72f71234fa81722afd95a3f997 upstream
Strangely I hadn't had noticed the existence of the list_entry_is_head()
in apparmor code when added the same one in the list.h. Luckily it's
fully identical and didn't break builds. In any case we don't need a
duplicate anymore, thus remove it from apparmor code.

a dedicated wake IRQ, we can get the following warning:
WARNING: CPU: 0 PID: 108 at kernel/irq/manage.c:526 enable_irq+0x40/0x94
[ 102.087860] Unbalanced enable for IRQ 147

This is because the dedicated wake IRQ for the device may have been
already enabled earlier by dev_pm_enable_wake_irq_check(). Fix the
issue by checking for runtime PM suspended status.
This issue can be easily reproduced by setting serial console log level
to zero, letting the serial console idle, and suspend the system from
an ssh terminal. On resume, dmesg will have the warning above.
The reason why I have not run into this issue earlier has been that I
typically run my PM test cases from on a serial console instead over ssh.

We do not need a SWIOTLB unless we have DRAM that is addressable beyond
the arm_dma_limit. Compare max_pfn with arm_dma_pfn_limit to determine

From: Eric Biggers <ebiggers(a)google.com>
If the file size is almost S64_MAX, the calculated number of Merkle tree
levels exceeds FS_VERITY_MAX_LEVELS, causing FS_IOC_ENABLE_VERITY to
fail. This is unintentional, since as the comment above the definition
of FS_VERITY_MAX_LEVELS states, it is enough for over U64_MAX bytes of
data using SHA-256 and 4K blocks. (Specifically, 4096*128**8 >= 2**64.)
The bug is actually that when the number of blocks in the first level is
calculated from i_size, there is a signed integer overflow due to i_size
being signed. Fix this by treating i_size is unsigned.
This was found by the new test "generic: test fs-verity EFBIG scenarios"
(https://lkml.kernel.org/r/b1d116cd4d0ea74b9cd86f349c672021e005a75c.16315584…).
This didn't affect ext4 or f2fs since those have a smaller maximum file
size, but it did affect btrfs which allows files up to S64_MAX bytes.

A race is possible when a process exits, its VMAs are removed
by exit_mmap() and at the same time userfaultfd_writeprotect() is
called.
The race was detected by KASAN on a development kernel, but it appears
to be possible on vanilla kernels as well.
Use mmget_not_zero() to prevent the race as done in other userfaultfd
operations.

Subject: [PATCH] net: stmmac: fix MAC not working when system resume back with
WoL active
We can reproduce this issue with below steps:
1) enable WoL on the host
2) host system suspended
3) remote client send out wakeup packets
We can see that host system resume back, but can't work, such as ping failed.
After a bit digging, this issue is introduced by the commit 46f69ded988d
("net: stmmac: Use resolved link config in mac_link_up()"), which use
the finalised link parameters in mac_link_up() rather than the
parameters in mac_config().
There are two scenarios for MAC suspend/resume in STMMAC driver:
1) MAC suspend with WoL inactive, stmmac_suspend() call
phylink_mac_change() to notify phylink machine that a change in MAC
state, then .mac_link_down callback would be invoked. Further, it will
call phylink_stop() to stop the phylink instance. When MAC resume back,
firstly phylink_start() is called to start the phylink instance, then
call phylink_mac_change() which will finally trigger phylink machine to
invoke .mac_config and .mac_link_up callback. All is fine since
configuration in these two callbacks will be initialized, that means MAC
can restore the state.
2) MAC suspend with WoL active, phylink_mac_change() will put link
down, but there is no phylink_stop() to stop the phylink instance, so it
will link up again, that means .mac_config and .mac_link_up would be
invoked before system suspended. After system resume back, it will do
DMA initialization and SW reset which let MAC lost the hardware setting
(i.e MAC_Configuration register(offset 0x0) is reset). Since link is up
before system suspended, so .mac_link_up would not be invoked after
system resume back, lead to there is no chance to initialize the
configuration in .mac_link_up callback, as a result, MAC can't work any
longer.
After discussed with Russell King [1], we confirm that phylink framework
have not take WoL into consideration yet. This patch calls
phylink_suspend()/phylink_resume() functions which is newly introduced
by Russell King to fix this issue.

The note in c2adda27d202f ("video: backlight: Add of_find_backlight helper
in backlight.c") says that gpio-backlight uses brightness as power state.
This has been fixed since in ec665b756e6f7 ("backlight: gpio-backlight:
Correct initial power state handling") and other backlight drivers do not
require this workaround. Drop the workaround.
This fixes the case where e.g. pwm-backlight can perfectly well be set to
brightness 0 on boot in DT, which without this patch leads to the display
brightness to be max instead of off.

A xHC USB 3 port might miss the first wake signal from a USB 3 device
if the port LFPS reveiver isn't enabled fast enough after xHC resume.
xHC host will anyway be resumed by a PME# signal, but will go back to
suspend if no port activity is seen.
The device resends the U3 LFPS wake signal after a 100ms delay, but
by then host is already suspended, starting all over from the
beginning of this issue.
USB 3 specs say U3 wake LFPS signal is sent for max 10ms, then device
needs to delay 100ms before resending the wake.
Don't suspend immediately if port activity isn't detected in resume.
Instead add a retry. If there is no port activity then delay for 120ms,
and re-check for port activity.

This reverts commit cc8870bf4c3ab0af385538460500a9d342ed945f.
Since commit cc8870bf4c3a ("ARM: imx6q: drop of_platform_default_populate()
from init_machine") the following errors are seen on boot:
[ 0.123372] imx6q_suspend_init: failed to find ocram device!
[ 0.123537] imx6_pm_common_init: No DDR LPM support with suspend -19!
, which break suspend/resume on imx6q/dl.
Revert the offeding commit to avoid the regression.
Thanks to Tim Harvey for bisecting this problem.

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.
Targeted tests
--------------
Test runs for patches always include a set of base tests, plus some
tests chosen based on the file paths modified by the patch. The latter
are called "targeted tests". If no targeted tests are run, that means
no patch-specific tests are available. Please, consider contributing a
targeted test for related patches to increase test coverage. See
https://docs.engineering.redhat.com/x/_wEZB for more details.
The note in c2adda27d202f ("video: backlight: Add of_find_backlight helper
in backlight.c") says that gpio-backlight uses brightness as power state.
This has been fixed since in ec665b756e6f7 ("backlight: gpio-backlight:
Correct initial power state handling") and other backlight drivers do not
require this workaround. Drop the workaround.
This fixes the case where e.g. pwm-backlight can perfectly well be set to
brightness 0 on boot in DT, which without this patch leads to the display
brightness to be max instead of off.

In MOTU protocol v2/v3, first two data chunks across 2nd and 3rd data
channels includes message bytes from device. The total size of message
is 48 bits per data block.
The 'data_block_message' tracepoints event produced by ALSA firewire-motu
driver exposes the sequence of messages to userspace in 64 bit storage,
however lower 32 bits are actually available since current implementation
truncates 16 bits in upper of the message as a result of bit shift
operation within 32 bit storage.
This commit fixes the bug by perform the bit shift in 64 bit storage.

This is a note to let you know that I've just added the patch titled
driver core: fw_devlink: Improve handling of cyclic dependencies
to my driver-core git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git
in the driver-core-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

Subject: driver core: fw_devlink: Improve handling of cyclic dependencies
When we have a dependency of the form:
Device-A -> Device-C
Device-B
Device-C -> Device-B
Where,
* Indentation denotes "child of" parent in previous line.
* X -> Y denotes X is consumer of Y based on firmware (Eg: DT).
We have cyclic dependency: device-A -> device-C -> device-B -> device-A
fw_devlink current treats device-C -> device-B dependency as an invalid
dependency and doesn't enforce it but leaves the rest of the
dependencies as is.
While the current behavior is necessary, it is not sufficient if the
false dependency in this example is actually device-A -> device-C. When
this is the case, device-C will correctly probe defer waiting for
device-B to be added, but device-A will be incorrectly probe deferred by
fw_devlink waiting on device-C to probe successfully. Due to this, none
of the devices in the cycle will end up probing.
To fix this, we need to go relax all the dependencies in the cycle like
we already do in the other instances where fw_devlink detects cycles.
A real world example of this was reported[1] and analyzed[2].

Subject: comedi: Fix memory leak in compat_insnlist()
`compat_insnlist()` handles the 32-bit version of the `COMEDI_INSNLIST`
ioctl (whenwhen `CONFIG_COMPAT` is enabled). It allocates memory to
temporarily hold an array of `struct comedi_insn` converted from the
32-bit version in user space. This memory is only being freed if there
is a fault while filling the array, otherwise it is leaked.
Add a call to `kfree()` to fix the leak.

Stable team,
here is a backport for 4.19 of
commit a3e03bc1368 ("KVM: s390: index kvm->arch.idle_mask by vcpu_idx")
This basically removes the kick_mask parts that were introduced with
kernel 5.0 and fixes up the location of the idle_mask to the older
place.
FWIW, it might be a good idea to also backport
8750e72a79dd ("KVM: remember position in kvm->vcpus array") to avoid
a performance regression for large guests (many vCPUs) when this patch
is applied.
@Paolo Bonzini, would you be ok with 8750e72a79dd in older stable releases?

💚 Pull requests are welcome for new tests or improvements to existing tests!
Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.
Targeted tests
--------------
Test runs for patches always include a set of base tests, plus some
tests chosen based on the file paths modified by the patch. The latter
are called "targeted tests". If no targeted tests are run, that means
no patch-specific tests are available. Please, consider contributing a
targeted test for related patches to increase test coverage. See
https://docs.engineering.redhat.com/x/_wEZB for more details.
With patch "drm/i915/vbt: Fix backlight parsing for VBT 234+"
the size of bdb_lfp_backlight_data structure has been increased,
causing if-statement in the parse_lfp_backlight function
that comapres this structure size to the one retrieved from BDB,
always to fail for older revisions.
This patch fixes it by comparing a total size of all fileds from
the structure (present before the change) with the value gathered from BDB.
Tested on Chromebook Pixelbook (Nocturne) (reports bdb->version = 221)

2.33.0.464.g1972c5931b-goog
This is a note to let you know that I've just added the patch titled
debugfs: debugfs_create_file_size(): use IS_ERR to check for error
to my driver-core git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git
in the driver-core-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.
Targeted tests
--------------
Test runs for patches always include a set of base tests, plus some
tests chosen based on the file paths modified by the patch. The latter
are called "targeted tests". If no targeted tests are run, that means
no patch-specific tests are available. Please, consider contributing a
targeted test for related patches to increase test coverage. See
https://docs.engineering.redhat.com/x/_wEZB for more details.

Test runs for patches always include a set of base tests, plus some
tests chosen based on the file paths modified by the patch. The latter
are called "targeted tests". If no targeted tests are run, that means
no patch-specific tests are available. Please, consider contributing a
targeted test for related patches to increase test coverage. See

Commit a799c2bd29d19c565 ("x86/setup: Consolidate early memory
reservations") introduced early_reserve_memory() to do all needed
initial memblock_reserve() calls in one function. Unfortunately the
call of early_reserve_memory() is done too late for Xen dom0, as in
some cases a Xen hook called by e820__memory_setup() will need those
memory reservations to have happened already.
Move the call of early_reserve_memory() to the beginning of
setup_arch() in order to avoid such problems.

Subject: [PATCH] x86/mce: Avoid infinite loop for copy from user recovery
There are two cases for machine check recovery:
1) The machine check was triggered by ring3 (application) code.
This is the simpler case. The machine check handler simply queues
work to be executed on return to user. That code unmaps the page
from all users and arranges to send a SIGBUS to the task that
triggered the poison.
2) The machine check was triggered in kernel code that is covered by
an exception table entry. In this case the machine check handler
still queues a work entry to unmap the page, etc. but this will
not be called right away because the #MC handler returns to the
fix up code address in the exception table entry.
Problems occur if the kernel triggers another machine check before the
return to user processes the first queued work item.
Specifically, the work is queued using the ->mce_kill_me callback
structure in the task struct for the current thread. Attempting to queue
a second work item using this same callback results in a loop in the
linked list of work functions to call. So when the kernel does return to
user, it enters an infinite loop processing the same entry for ever.
There are some legitimate scenarios where the kernel may take a second
machine check before returning to the user.
1) Some code (e.g. futex) first tries a get_user() with page faults
disabled. If this fails, the code retries with page faults enabled
expecting that this will resolve the page fault.
2) Copy from user code retries a copy in byte-at-time mode to check
whether any additional bytes can be copied.
On the other side of the fence are some bad drivers that do not check
the return value from individual get_user() calls and may access
multiple user addresses without noticing that some/all calls have
failed.
Fix by adding a counter (current->mce_count) to keep track of repeated
machine checks before task_work() is called. First machine check saves
the address information and calls task_work_add(). Subsequent machine
checks before that task_work call back is executed check that the address
is in the same page as the first machine check (since the callback will
offline exactly one page).
Expected worst case is four machine checks before moving on (e.g. one
user access with page faults disabled, then a repeat to the same address
with page faults enabled ... repeat in copy tail bytes). Just in case
there is some code that loops forever enforce a limit of 10.

Subject: [PATCH] s390/pci_mmio: fully validate the VMA before calling
follow_pte()
We should not walk/touch page tables outside of VMA boundaries when
holding only the mmap sem in read mode. Evil user space can modify the
VMA layout just before this function runs and e.g., trigger races with
page table removal code since commit dd2283f2605e ("mm: mmap: zap pages
with read mmap_sem in munmap").
find_vma() does not check if the address is >= the VMA start address;
use vma_lookup() instead.

[PATCH v1 00/12] mm/memory_hotplug: "auto-movable" online policy and memory
groups.
These patches make sense even without the other series, therefore I pulled

[1] https://lkml.kernel.org/r/20210607195430.48228-1-david@redhat.com
This patch (of 4):
Checkpatch complained on a follow-up patch that we are using "unsigned"
here, which defaults to "unsigned int" and checkpatch is correct.
As we will search for a fitting zone using the wrong pfn, we might end
up onlining memory to one of the special kernel zones, such as ZONE_DMA,
which can end badly as the onlined memory does not satisfy properties of
these zones.
Use "unsigned long" instead, just as we do in other places when handling
PFNs. This can bite us once we have physical addresses in the range of
multiple TB.

Patch series "mm/memory_hotplug: preparatory patches for new online policy and memory"
These are all cleanups and one fix previously sent as part of [1]:
[PATCH v1 00/12] mm/memory_hotplug: "auto-movable" online policy and memory
groups.
These patches make sense even without the other series, therefore I pulled
them out to make the other series easier to digest.
[1] https://lkml.kernel.org/r/20210607195430.48228-1-david@redhat.com
This patch (of 4):
Checkpatch complained on a follow-up patch that we are using "unsigned"
here, which defaults to "unsigned int" and checkpatch is correct.
As we will search for a fitting zone using the wrong pfn, we might end
up onlining memory to one of the special kernel zones, such as ZONE_DMA,
which can end badly as the onlined memory does not satisfy properties of
these zones.
Use "unsigned long" instead, just as we do in other places when handling
PFNs. This can bite us once we have physical addresses in the range of
multiple TB.

"PAGESIZE / 512" is the number of ECC chunks.
"ECC_BYTES" is the number of bytes needed to store a single ECC code.
"2" is the space reserved by the bad block marker.
"2 + (PAGESIZE / 512) * ECC_BYTES" should of course be lower or equal
than the total number of OOB bytes, otherwise it won't fit.
Fix the equation by substituting s/>=/<=/.

The fault happens because kern_addr_valid() dereferences existent but not
present PMD in the high kernel mappings.
Such PMDs are created when free_kernel_image_pages() frees regions larger
than 2Mb. In this case, a part of the freed memory is mapped with PMDs and
the set_memory_np_noalias() -> ... -> __change_page_attr() sequence will
mark the PMD as not present rather than wipe it completely.
Have kern_addr_valid() check whether higher level page table entries are
present before trying to dereference them to fix this issue and to avoid
similar issues in the future.
Stable backporting note:
------------------------
Note that the stable marking is for all active stable branches because
there could be cases where pagetable entries exist but are not valid -
see 9a14aefc1d28 ("x86: cpa, fix lookup_address"), for example. So make
sure to be on the safe side here and use pXY_present() accessors rather
than pXY_none() which could #GP when accessing pages in the direct map.
Also see:
c40a56a7818c ("x86/mm/init: Remove freed kernel image areas from alias mapping")
for more info.

Subject: [PATCH] powerpc/64s: system call rfscv workaround for TM bugs
The rfscv instruction does not work correctly with the fake-suspend mode
in POWER9, which can end up with the hypervisor restoring an incorrect
checkpoint.
Work around this by setting the _TIF_RESTOREALL flag if a system call
returns to a transaction active state, causing rfid to be used instead
of rfscv to return, which will do the right thing. The contents of the
registers are irrelevant because they will be overwritten in this case
anyway.

Subject: [PATCH] drm/amdgpu: Drop inline from
amdgpu_ras_eeprom_max_record_count
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This was unusual; normally, inline functions are declared static as
well, and defined in a header file if used by multiple compilation
units. The latter would be more involved in this case, so just drop
the inline declaration for now.
Fixes compile failure building for ppc64le on RHEL 8:
