4be708d0c4 Merge branch 'tools-ynl-fix-errors-reported-by-ruff'
Matthieu Baerts says:

====================
tools: ynl: fix errors reported by Ruff

When looking at the YNL code to add a new feature, my text editor
automatically executed 'ruff check', and found out at least one
interesting error: one variable was used while not being defined.

I then decided to fix this error, and all the other ones reported by
Ruff. After this series, 'ruff check' reports no more errors with
version 0.12.12.
====================

  f-strings are a convenient way to format strings, but they are not

5537a46794 net: usb: asix: ax88772: drop phylink use in PM to avoid MDIO runtime PM wakeups
Drop phylink_{suspend,resume}() from ax88772 PM callbacks.

MDIO bus accesses have their own runtime-PM handling and will try to
wake the device if it is suspended. Such wake attempts must not happen
from PM callbacks while the device PM lock is held. Since phylink
{sus|re}sume may trigger MDIO, it must not be called in PM context.

No extra phylink PM handling is required for this driver:
- .ndo_open/.ndo_stop control the phylink start/stop lifecycle.
- ethtool/phylib entry points run in process context, not PM.
- phylink MAC ops program the MAC on link changes after resume.

6fef6ae764 net: ethtool: fix wrong type used in struct kernel_ethtool_ts_info
In C, enumerated types do not have a defined size, apart from being
compatible with one of the standard types. This allows an ABI /
compiler to choose the type of an enum depending on the values it
needs to store, and storing larger values in it can lead to undefined
behaviour.

The tx_type and rx_filters members of struct kernel_ethtool_ts_info
are defined as enumerated types, but are bit arrays, where each bit
is defined by the enumerated type. This means they typically store
values in excess of the maximum value of the enumerated type, in
fact (1 << max_value) and thus must not be declared using the
enumated type.

Fix both of these to use u32, as per the corresponding __u32 UAPI type.

91494dee10 xe: populate buffers before exporting them.
Before exporting a buffer, make sure it has been populated with
pages at least once.

While discussing cgroups we noticed a problem where you could export
a BO to a dma-buf without having it ever being backed or accounted for.

This meant in low memory situations or eventually with cgroups, a
lower privledged process might cause the compositor to try and allocate
a lot of memory on it's behalf and this could fail. At least make
sure the exporter has managed to allocate the RAM at least once
before exporting the object.

This only applies currently to TTM_PL_SYSTEM objects, because
GTT objects get populated on first validate, and VRAM doesn't
use TT.

Before exporting a buffer, make sure it has been populated with
pages at least once.

While discussing cgroups we noticed a problem where you could export
a BO to a dma-buf without having it ever being backed or accounted for.

This meant in low memory situations or eventually with cgroups, a
lower privledged process might cause the compositor to try and allocate
a lot of memory on it's behalf and this could fail. At least make
sure the exporter has managed to allocate the RAM at least once
before exporting the object.

This only applies currently to TTM_PL_SYSTEM objects, because
GTT objects get populated on first validate, and VRAM doesn't
use TT.

d2c7731593 audit: fix skb leak when audit rate limit is exceeded
When configuring a small audit rate limit in
/etc/audit/rules.d/audit.rules:
-a always,exit -F arch=b64 -S openat -S truncate -S ftruncate
-F exit=-EACCES -F auid>=1000 -F auid!=4294967295 -k access -r 100

And then repeatedly triggering permission denied as a normal user:
while :; do cat /proc/1/environ; done

We can see the messages in kernel log:
  [ 2531.862184] audit: rate limit exceeded

The unreclaimable slab objects start to leak quickly. With kmemleak
enabled, many call traces appear like:
unreferenced object 0xffff99144b13f600 (size 232):
  comm "cat", pid 1100, jiffies 4294739144
  hex dump (first 32 bytes):
    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................
    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................
  backtrace (crc 8540ec4f):
    kmemleak_alloc+0x4a/0x90
    kmem_cache_alloc_node+0x2ea/0x390
    __alloc_skb+0x174/0x1b0
    audit_log_start+0x198/0x3d0
    audit_log_proctitle+0x32/0x160
    audit_log_exit+0x6c6/0x780
    __audit_syscall_exit+0xee/0x140
    syscall_exit_work+0x12b/0x150
    syscall_exit_to_user_mode_prepare+0x39/0x80
    syscall_exit_to_user_mode+0x11/0x260
    do_syscall_64+0x8c/0x180
    entry_SYSCALL_64_after_hwframe+0x78/0x80

This shows that the skb allocated in audit_log_start() and queued
onto skb_list is never freed.

In audit_log_end(), each skb is dequeued from skb_list and passed
to __audit_log_end(). However, when the audit rate limit is exceeded,
__audit_log_end() simply prints "rate limit exceeded" and returns
without processing the skb. Since the skb is already removed from
skb_list, audit_buffer_free() cannot free it later, leading to a
memory leak.

Fix this by freeing the skb when the rate limit is exceeded.

avoids allocating too much memory, as the io_overflow_cqe size includes
the list member required to queue them too.

60e9f776b7 drm/msm/registers: Generate _HI/LO builders for reg64
The upstream mesa copy of the GPU regs has shifted more things to reg64
instead of seperate 32b HI/LO reg32's.  This works better with the "new-
style" c++ builders that mesa has been migrating to for a6xx+ (to better
handle register shuffling between gens), but it leaves the C builders
with missing _HI/LO builders.

So handle the special case of reg64, automatically generating the
missing _HI/LO builders.

Since these generated files are no longer checked in, either in mesa or

These were semi-nerf'd on the kernel side, in the name of build
reproducibility, by commit ba64c6737f ("drivers: gpu: drm: msm:

kernel specific.  We can just reduce the divergence between kernel
