1f8d439688 RDMA/bnxt_re: Check cqe flags to know imm_data vs inv_irkey
[ Upstream commit 808ca6de989c598bc5af1ae0ad971a66077efac0 ]

Invalidate rkey is cpu endian and immediate data is in big endian format.
Both immediate data and invalidate the remote key returned by
HW is in little endian format.

While handling the commit in fixes tag, the difference between
immediate data and invalidate rkey endianness was not considered.

Without changes of this patch, Kernel ULP was failing while processing
inv_rkey.

dmesg log snippet -
nvme nvme0: Bogus remote invalidation for rkey 0x2000019Fix in this patch

Do endianness conversion based on completion queue entry flag.
Also, the HW completions are already converted to host endianness in
bnxt_qplib_cq_process_res_rc and bnxt_qplib_cq_process_res_ud and there
is no need to convert it again in bnxt_re_poll_cq. Modified the union to
hold the correct data type.

2014fcea19 mtd: rawnand: atmel: Fix possible memory leak
[ Upstream commit 6d734f1bfc336aaea91313a5632f2f197608fadd ]

The pmecc "user" structure is allocated in atmel_pmecc_create_user() and
was supposed to be freed with atmel_pmecc_destroy_user(), but this other
helper is never called. One solution would be to find the proper
location to call the destructor, but the trend today is to switch to
device managed allocations, which in this case fits pretty well.

Replace kzalloc() by devm_kzalloc() and drop the destructor entirely.

6f0198b5f3 powerpc/vdso: Flag VDSO64 entry points as functions
[ Upstream commit 0161bd38c24312853ed5ae9a425a1c41c4ac674a ]

On powerpc64 as shown below by readelf, vDSO functions symbols have

To overcome that, commit ba83b3239e65 ("selftests: vDSO: fix vDSO
symbols lookup for powerpc64") was applied to have selftests also
look for NOTYPE symbols, but the correct fix should be to flag VDSO
entry points as functions.

The original commit that brought VDSO support into powerpc/64 has the
following explanation:

    Note that the symbols exposed by the vDSO aren't "normal" function symbols, apps
    can't be expected to link against them directly, the vDSO's are both seen
    as if they were linked at 0 and the symbols just contain offsets to the
    various functions.  This is done on purpose to avoid a relocation step
    (ppc64 functions normally have descriptors with abs addresses in them).
    When glibc uses those functions, it's expected to use it's own trampolines
    that know how to reach them.

The descriptors it's talking about are the OPD function descriptors
used on ABI v1 (big endian). But it would be more correct for a text
symbol to have type function, even if there's no function descriptor
for it.

glibc has a special case already for handling the VDSO symbols which
creates a fake opd pointing at the kernel symbol. So changing the VDSO
symbol type to function shouldn't affect that.

For ABI v2, there is no function descriptors and VDSO functions can
safely have function type.

So lets flag VDSO entry points as functions and revert the
selftest change.

9b6d18b6e8 trace/trace_event_perf: remove duplicate samples on the first tracepoint event
[ Upstream commit afe5960dc208fe069ddaaeb0994d857b24ac19d1 ]

When a tracepoint event is created with attr.freq = 1,
'hwc->period_left' is not initialized correctly. As a result,
in the perf_swevent_overflow() function, when the first time the event occurs,
it calculates the event overflow and the perf_swevent_set_period() returns 3,
this leads to the event are recorded for three duplicate times.

Step to reproduce:
    1. Enable the tracepoint event & starting tracing
         $ echo 1 > /sys/kernel/tracing/events/module/module_free
         $ echo 1 > /sys/kernel/tracing/tracing_on

    2. Record with perf
         $ perf record -a --strict-freq -F 1 -e "module:module_free"

    3. Trigger module_free event.
         $ modprobe -i sunrpc
         $ modprobe -r sunrpc

Result:
     - Trace pipe result:
         $ cat trace_pipe
         modprobe-174509  [003] .....  6504.868896: module_free: sunrpc

     - perf sample:
         modprobe  174509 [003]  6504.868980: module:module_free: sunrpc
         modprobe  174509 [003]  6504.868980: module:module_free: sunrpc
         modprobe  174509 [003]  6504.868980: module:module_free: sunrpc

By setting period_left via perf_swevent_set_period() as other sw_event did,
This problem could be solved.

After patch:
     - Trace pipe result:
         $ cat trace_pipe
         modprobe 1153096 [068] 613468.867774: module:module_free: xfs

     - perf sample

3cc7dfd720 netpoll: Use rcu_access_pointer() in netpoll_poll_lock
[ Upstream commit a57d5a72f8dec7db8a79d0016fb0a3bdecc82b56 ]

The ndev->npinfo pointer in netpoll_poll_lock() is RCU-protected but is
being accessed directly for a NULL check. While no RCU read lock is held
in this context, we should still use proper RCU primitives for
consistency and correctness.

Replace the direct NULL check with rcu_access_pointer(), which is the
appropriate primitive when only checking for NULL without dereferencing
the pointer. This function provides the necessary ordering guarantees
without requiring RCU read-side protection.

74357d0b5c ALSA: 6fire: Release resources at card release
[ Upstream commit a0810c3d6dd2d29a9b92604d682eacd2902ce947 ]

The current 6fire code tries to release the resources right after the
call of usb6fire_chip_abort().  But at this moment, the card object
might be still in use (as we're calling snd_card_free_when_closed()).

For avoid potential UAFs, move the release of resources to the card's
private_free instead of the manual call of usb6fire_chip_destroy() at
the USB disconnect callback.

3993edf44d ALSA: caiaq: Use snd_card_free_when_closed() at disconnection
[ Upstream commit b04dcbb7f7b1908806b7dc22671cdbe78ff2b82c ]

The USB disconnect callback is supposed to be short and not too-long
waiting.  OTOH, the current code uses snd_card_free() at
disconnection, but this waits for the close of all used fds, hence it
can take long.  It eventually blocks the upper layer USB ioctls, which
may trigger a soft lockup.

An easy workaround is to replace snd_card_free() with
snd_card_free_when_closed().  This variant returns immediately while
the release of resources is done asynchronously by the card device
release at the last close.

This patch also splits the code to the disconnect and the free phases;
the former is called immediately at the USB disconnect callback while
the latter is called from the card destructor.

bb43628a78 drm/omap: Fix locking in omap_gem_new_dmabuf()
[ Upstream commit e6a1c4037227539373c8cf484ace83833e2ad6a2 ]

omap_gem_new_dmabuf() creates the new gem object, and then takes and
holds the omap_obj->lock for the rest of the function. This has two
issues:

- omap_gem_free_object(), which is called in the error paths, also takes
  the same lock, leading to deadlock
- Even if the above wouldn't happen, in the error cases
  omap_gem_new_dmabuf() still unlocks omap_obj->lock, even after the
  omap_obj has already been freed.

Furthermore, I don't think there's any reason to take the lock at all,
as the object was just created and not yet shared with anyone else.

To fix all this, drop taking the lock.

5f177fb9d0 wifi: ath9k: add range check for conn_rsp_epid in htc_connect_service()
[ Upstream commit 8619593634cbdf5abf43f5714df49b04e4ef09ab ]

I found the following bug in my fuzzer:

  UBSAN: array-index-out-of-bounds in drivers/net/wireless/ath/ath9k/htc_hst.c:26:51

Since this bug has been confirmed to be caused by insufficient verification
of conn_rsp_epid, I think it would be appropriate to add a range check for
conn_rsp_epid to htc_connect_service() to prevent the bug from occurring.

[ Upstream commit 53bd7c1c0077db533472ae32799157758302ef48 ]

The INTERVAL_TREE_DEFINE() uncoditionally provides a bunch of helper

prevents kernel builds with clang, `make W=1` and CONFIG_WERROR=y:

d74e926ce5 ARM: dts: cubieboard4: Fix DCDC5 regulator constraints
[ Upstream commit dd36ad71ad65968f97630808bc8d605c929b128e ]

The DCDC5 voltage rail in the X-Powers AXP809 PMIC has a resolution of
50mV, so the currently enforced limits of 1.475 and 1.525 volts cannot
be set, when the existing regulator value is beyond this range.

This will lead to the whole regulator driver to give up and fail
probing, which in turn will hang the system, as essential devices depend
on the PMIC.
In this case a bug in U-Boot set the voltage to 1.75V (meant for DCDC4),
and the AXP driver's attempt to correct this lead to this error:
==================
[    4.447653] axp20x-rsb sunxi-rsb-3a3: AXP20X driver loaded

Set the limits to values that can be programmed, so any correction will
be successful.

Fix undefined behavior caused by left-shifting a negative value in the

The variable bad_data_bit ranges from 0 to 63. When it is less than 32,
bad_data_bit - 32 becomes negative, and left-shifting by a negative
value in C is undefined behavior.

Fix this by combining cap_high and cap_low into a 64-bit variable.

baccb5e125 hfsplus: don't query the device logical block size multiple times
[ Upstream commit 1c82587cb57687de3f18ab4b98a8850c789bedcf ]

Devices block sizes may change. One of these cases is a loop device by
using ioctl LOOP_SET_BLOCK_SIZE.

While this may cause other issues like IO being rejected, in the case of
hfsplus, it will allocate a block by using that size and potentially write
out-of-bounds when hfsplus_read_wrapper calls hfsplus_submit_bio and the
latter function reads a different io_size.

Using a new min_io_size initally set to sb_min_blocksize works for the
purposes of the original fix, since it will be set to the max between
HFSPLUS_SECTOR_SIZE and the first seen logical block size. We still use the
max between HFSPLUS_SECTOR_SIZE and min_io_size in case the latter is not
initialized.

Tested by mounting an hfsplus filesystem with loop block sizes 512, 1024
and 4096.

36a305d0ca s390/syscalls: Avoid creation of arch/arch/ directory
[ Upstream commit 0708967e2d56e370231fd07defa0d69f9ad125e8 ]

Building the kernel with ARCH=s390 creates a weird arch/arch/ directory.

  $ find arch/arch
  arch/arch
  arch/arch/s390
  arch/arch/s390/include
  arch/arch/s390/include/generated
  arch/arch/s390/include/generated/asm
  arch/arch/s390/include/generated/uapi
  arch/arch/s390/include/generated/uapi/asm

The root cause is 'targets' in arch/s390/kernel/syscalls/Makefile,
where the relative path is incorrect.

Strictly speaking, 'targets' was not necessary in the first place
because this Makefile uses 'filechk' instead of 'if_changed'.

However, this commit keeps it, as it will be useful when converting
'filechk' to 'if_changed' later.

[ Upstream commit 47bc874427382018fa2e3e982480e156271eee70 ]

Sometime long ago the m68k IRQ code was refactored and the interrupt
numbers for SCSI controller on this board ended up wrong, and it hasn't
worked since.

The PCC adds 0x40 to the vector for its interrupts so they end up in
the user interrupt range. Hence, the kernel number should be the kernel
offset for user interrupt range + the PCC interrupt number.

bb7ac96670 initramfs: avoid filename buffer overrun
[ Upstream commit e017671f534dd3f568db9e47b0583e853d2da9b5 ]

The initramfs filename field is defined in
Documentation/driver-api/early-userspace/buffer-format.rst as:

 37 cpio_file := ALGN(4) + cpio_header + filename + "\0" + ALGN(4) + data
...
 55 ============= ================== =========================
 56 Field name    Field size         Meaning
 57 ============= ================== =========================
...
 70 c_namesize    8 bytes            Length of filename, including final \0

When extracting an initramfs cpio archive, the kernel's do_name() path
handler assumes a zero-terminated path at @collected, passing it
directly to filp_open() / init_mkdir() / init_mknod().

If a specially crafted cpio entry carries a non-zero-terminated filename
and is followed by uninitialized memory, then a file may be created with
trailing characters that represent the uninitialized memory. The ability
to create an initramfs entry would imply already having full control of
the system, so the buffer overrun shouldn't be considered a security
vulnerability.

Append the output of the following bash script to an existing initramfs
and observe any created /initramfs_test_fname_overrunAA* path. E.g.
  ./reproducer.sh | gzip >> /myinitramfs

It's easiest to observe non-zero uninitialized memory when the output is
gzipped, as it'll overflow the heap allocated @out_buf in __gunzip(),
rather than the initrd_start+initrd_size block.

termpadlen=$(( 1 + ((4 - ((110 + $namelen) & 3)) % 4) ))
printf "%.s${nilchar}" $(seq 1 $termpadlen)
---- reproducer.sh ----

Symlink filename fields handled in do_symlink() won't overrun past the
data segment, due to the explicit zero-termination of the symlink
target.

Fix filename buffer overrun by aborting the initramfs FSM if any cpio
entry doesn't carry a zero-terminator at the expected (name_len - 1)
offset.

28202c1d05 nvme: fix metadata handling in nvme-passthrough
[ Upstream commit 7c2fd76048e95dd267055b5f5e0a48e6e7c81fd9 ]

On an NVMe namespace that does not support metadata, it is possible to
send an IO command with metadata through io-passthru. This allows issues
like [1] to trigger in the completion code path.
nvme_map_user_request() doesn't check if the namespace supports metadata
before sending it forward. It also allows admin commands with metadata to
be processed as it ignores metadata when bdev == NULL and may report
success.

Reject an IO command with metadata when the NVMe namespace doesn't
support it and reject an admin command if it has metadata.

seq_printf is costy, on a system with n CPUs, reading /proc/softirqs
would yield 10*n decimal values, and the extra cost parsing format string
grows linearly with number of cpus. Replace seq_printf with
seq_put_decimal_ull_width have significant performance improvement.
On an 8CPUs system, reading /proc/softirqs show ~40% performance
gain with this patch.

Users of the interface who also allow COMPILE_TEST will cause the above build
error so provide an inline stub to fix that.

9c058b8b29 selftests/watchdog-test: Fix system accidentally reset after watchdog-test
[ Upstream commit dc1308bee1ed03b4d698d77c8bd670d399dcd04d ]

When running watchdog-test with 'make run_tests', the watchdog-test will
be terminated by a timeout signal(SIGTERM) due to the test timemout.

And then, a system reboot would happen due to watchdog not stop. see
the dmesg as below:
```
[ 1367.185172] watchdog: watchdog0: watchdog did not stop!
```

Fix it by registering more signals(including SIGTERM) in watchdog-test,
where its signal handler will stop the watchdog.

After that
 # timeout 1 ./watchdog-test
 Watchdog Ticking Away!
 .
 Stopping watchdog ticks...

cc1ecdd66d mac80211: fix user-power when emulating chanctx
[ Upstream commit 9b15c6cf8d2e82c8427cd06f535d8de93b5b995c ]

ieee80211_calc_hw_conf_chan was ignoring the configured
user_txpower.  If it is set, use it to potentially decrease
txpower as requested.

c0668b709d ASoC: Intel: bytcr_rt5640: Add DMI quirk for Vexia Edu Atla 10 tablet
[ Upstream commit 0107f28f135231da22a9ad5756bb16bd5cada4d5 ]

The Vexia Edu Atla 10 tablet mostly uses the BYTCR tablet defaults,
but as happens on more models it is using IN1 instead of IN3 for
its internal mic and JD_SRC_JD2_IN4N instead of JD_SRC_JD1_IN4P
for jack-detection.

Add a DMI quirk for this to fix the internal-mic and jack-detection.

36b537e8f3 mm: revert "mm: shmem: fix data-race in shmem_getattr()"
commit d1aa0c04294e29883d65eac6c2f72fe95cc7c049 upstream.

Revert d949d1d14fa2 ("mm: shmem: fix data-race in shmem_getattr()") as
suggested by Chuck [1].  It is causing deadlocks when accessing tmpfs over
NFS.

As Hugh commented, "added just to silence a syzbot sanitizer splat: added
where there has never been any practical problem".

fef0b00f31 kbuild: Use uname for LINUX_COMPILE_HOST detection
commit 1e66d50ad3a1dbf0169b14d502be59a4b1213149 upstream.

`hostname` may not be present on some systems as it's not mandated by
POSIX/SUSv4. This isn't just a theoretical problem: on Arch Linux,
`hostname` is provided by `inetutils`, which isn't part of the base
distribution.

    ./scripts/mkcompile_h: line 38: hostname: command not found

Use `uname -n` instead, which is more likely to be available (and
mandated by standards).

commit a4aebaf6e6efff548b01a3dc49b4b9074751c15b upstream.

When CONFIG_DVB_DYNAMIC_MINORS, ret is not initialized, and a
semaphore is left at the wrong state, in case of errors.

Make the code simpler and avoid mistakes by having just one error
check logic used weather DVB_DYNAMIC_MINORS is used or not.

00bff71745 Revert "mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K"
commit 1635e407a4a64d08a8517ac59ca14ad4fc785e75 upstream.

The commit 8396c793ffdf ("mmc: dw_mmc: Fix IDMAC operation with pages
bigger than 4K") increased the max_req_size, even for 4K pages, causing
various issues:
- Panic booting the kernel/rootfs from an SD card on Rockchip RK3566
- Panic booting the kernel/rootfs from an SD card on StarFive JH7100
- "swiotlb buffer is full" and data corruption on StarFive JH7110

At this stage no fix have been found, so it's probably better to just
revert the change.

This reverts commit 8396c793ffdf28bb8aee7cfe0891080f8cab7890.
