- Ignore Presence Detect Changed caused by DPC. pciehp already ignores
Link Down/Up events caused by DPC, but on slots using in-band presence
detect, DPC causes a spurious Presence Detect Changed event (Lukas
Wunner)
- Ignore Link Down/Up caused by Secondary Bus Reset. On hotplug ports
using in-band presence detect, the reset causes a Presence Detect Changed
event, which mistakenly caused teardown and re-enumeration of the device.
Drivers may need to annotate code that resets their device (Lukas Wunner)

When CONFIG_SHMEM is not set, the following compiler error occurs:
ld: vmlinux.o: in function `ttm_backup_backup_page':
(.text+0x10363bc): undefined reference to `shmem_writeout'
make[3]: *** [/work/build/trace/nobackup/linux.git/scripts/Makefile.vmlinux:91: vmlinux.unstripped] Error 1
This is due to the replacement of writepage and calling swap_writeout()
and shmem_writeout() directly. The issue is that when CONFIG_SHMEM is
not defined, shmem_writeout() is also not defined.
The function ttm_backup_backup_page() called mapping->a_ops->writepage()
which was then changed to call shmem_writeout() directly.
Even before commit 84798514db50 ("mm: Remove swap_writepage() and
shmem_writepage()"), it didn't make sense to call anything other than
shmem_writeout() as the ttm_backup deals only with shmem folios.
Have DRM_TTM config option select SHMEM to guarantee that
shmem_writeout() is available.

gve_alloc_pending_packet() can return NULL, but gve_tx_add_skb_dqo()
did not check for this case before dereferencing the returned pointer.
Add a missing NULL check to prevent a potential NULL pointer
dereference when allocation fails.
This improves robustness in low-memory scenarios.

There was a typo that caused the extended FP state to be copied into the
wrong location on 32 bit. On 32 bit we only store the xstate internally
as that already contains everything. However, for compatibility, the
mcontext on 32 bit first contains the legacy FP state and then the
xstate.
The code copied the xstate on top of the legacy FP state instead of
using the correct offset. This offset was already calculated in the
xstate_* variables, so simply switch to those to fix the problem.
With this SECCOMP mode works on 32 bit, so lift the restriction.

Pull tracing fixes from Steven Rostedt:
- Fix UAF in module unload in ftrace when there's a bug in the module
If a module is buggy and triggers ftrace_disable which is set when an
anomaly is detected, when it gets unloaded it doesn't free the hooks
into kallsyms, and when a kallsyms lookup is performed it may access
the mod->modname field and crash via UAF.
Fix this by still freeing the mod_maps that are attached to kallsyms
on module unload regardless if ftrace_disable is set or not.
- Do not bother allocating mod_maps for kallsyms if ftrace_disable is
set
- Remove unused trace events
When a trace event or tracepoint is created but not used, it still
creates the code and data structures needed for that trace event.
This just wastes memory.
Remove the trace events that are created but not used. This does not
remove trace events that are created but are not used due configs not
being set. That will be handled later. This only removes events that
have no user under any config.

"Framebuffer Subsystem (fbdev):

- 'framebuffer_alloc()' initializes the blank state to FB_BLANK_UNBLANK
- 'register_framebuffer()' sets the state to 'FB_BLANK_POWERDOWN' if
an 'fb_blank' callback exists, ensuring 'FB_EVENT_BLANK' listeners
correctly see the display being turned on during the first modeset
- The 'FB_EVENT_BLANK' event data now includes both the new and the
old blank states

notify them of blank state changes, instead of relying on fbdev
event notifiers

When the dax_fault_actor() helper was factored out, it removed the calls
to the dax_pmd_insert_mapping and dax_insert_mapping events but never
removed the events themselves. As each event created takes up memory
(roughly 5K each), this is a waste as it is never used.
Remove the unused dax_pmd_insert_mapping and dax_insert_mapping trace
events.

with 'V4L2_CID_FLASH_DURATION'
Texas Instruments TPS6131x:
- Add a new driver for the TPS61310/TPS61311 flash LED controllers
- The driver supports the device's three constant-current sinks for
flash and torch modes
LED Core:
- Prevent potential 'snprintf()' truncations in LED names by checking
for buffer overflows
ChromeOS EC LEDs:
- Avoid a -Wflex-array-member-not-at-end GCC warning by replacing an
on-stack flexible structure definition with a utility function call
Multicolor LEDs:
- Fix issue where setting multi_intensity while software blinking is
active could stop blinking
PCA955x LEDs:
- Avoid potential buffer overflow when creating default labels by
changing a field's type to 'u8' and updating format specifiers
PCA995x LEDs:
- Fix a typo (stray space) in an 'of_device_id' entry in the
'pca995x_of_match' table
Kconfig:
- Prevent LED drivers from being enabled by default when
'COMPILE_TEST' is set
Device Property API:
- Split 'device_get_child_node_count()' into a new helper
'fwnode_get_child_node_count()' that doesn't require a device
struct, making the API more symmetrical
Driver Modernization (using 'fwnode_get_child_node_count()'):
- Update 'leds-pwm-multicolor', 'leds-ncp5623' and 'leds-ncp5623' to
use the new 'fwnode_get_child_node_count()' helper, removing their
custom implementation
- As above in the USB Type-C TCPM driver
Driver Modernization (using new GPIO setter callbacks):
- Convert 'leds-lgm-sso' to use new GPIO line value setter callbacks
which return an integer for error handling
- Convert 'leds-pca955x', 'leds-pca9532' and 'leds-tca6507' to use
new GPIO setter callbacks
Documentation:
- Remove the '.rst' extension for 'leds-st1202' in the documentation
index for consistency
LP8860 LEDs:
- Use 'regmap_multi_reg_write()' for EEPROM writes instead of manual
looping
- Use scoped mutex guards and 'devm_mutex_init()' to simplify
function exits and ensure automatic cleanup
- Remove default register definitions that are unused when regmap
caching is not active
- Use 'devm_regulator_get_enable_optional()' to handle the optional
regulator, simplifying enabling and removing manual disabling
- Refactor 'lp8860_unlock_eeprom()' to only perform the unlock
operation, removing the lock part and an unnecessary parameter
- Use a 'devm' action to disable the enable-GPIO, simplifying cleanup
and error paths, and remove the now-empty '.remove()' function
Turris Omnia LEDs:
- Drop unnecessary commas in terminator entries of 'struct attribute'
and 'struct of_device_id' arrays
MT6370 RGB LEDs:
- Use the 'LINEAR_RANGE()' for defining 'struct linear_range' entries
to improve robustness
Texas Instruments TPS6131x:

In the idle CPU selection logic, attempting cross-node searches adds
unnecessary complexity when CONFIG_NUMA is disabled.
Since there's no meaningful concept of nodes in this case, simplify the
logic by restricting the idle CPU search to the current node only.

This commit doesn't fix any bug, it is just code cleanup. Use the
function format_dev_t instead of sprintf, because format_dev_t does the
same thing.
Remove the useless memset call.
An unsigned integer can take at most 10 digits, so extend the array size
to 22. (note that because the range of minor and major numbers is limited,
the size 16 could not be exceeded, thus this function couldn't write
beyond string end)

If some of the arguments "check_at_most_once", "ignore_zero_blocks",
"use_fec_from_device", "root_hash_sig_key_desc" were specified more than
once on the target line, a memory leak would happen.

verity_verify_sig_parse_opt_args.

There's a tiny race condition in dm-mirror. The functions queue_bio and
write_callback grab a spinlock, add a bio to the list, drop the spinlock
and wake up the mirrord thread that processes bios in the list.
It may be possible that the mirrord thread processes the bio just after
spin_unlock_irqrestore is called, before wakeup_mirrord. This spurious
wake-up is normally harmless, however if the device mapper device is
unloaded just after the bio was processed, it may be possible that
wakeup_mirrord(ms) uses invalid "ms" pointer.
Fix this bug by moving wakeup_mirrord inside the spinlock.

Get rid of the crit lock.
That frees us from the error prone logic of try_locks.
Thanks to netdev_lock() by Jakub it is now easy, and in most cases we were
protected by it already - replace crit lock by netdev lock when it was not
the case.
Lockdep reports that we should cancel the work under crit_lock [splat1],
and that was the scheme we have mostly followed since [1] by Slawomir.
But when that is done we still got into deadlocks [splat2]. So instead
we should look at the bigger problem, namely "weird locking/scheduling"
of the iavf. The first step to fix that is to remove the crit lock.
I will followup with a -next series that simplifies scheduling/tasks.
Cancel the work without netdev lock (weird unlock+lock scheme),
to fix the [splat2] (which would be totally ugly if we would kept
the crit lock).
Extend protected part of iavf_watchdog_task() to include scheduling
more work.
Note that the removed comment in iavf_reset_task() was misplaced,
it belonged to inside of the removed if condition, so it's gone now.
[splat1] - w/o this patch - The deadlock during VF removal:

sh/3825 is trying to acquire lock:

Fix an obvious violation of lock ordering.
Jakub's [1] added netdev_lock() call that is wrong ordered wrt RTNL,
but the Fixes tag points to crit_lock being wrongly placed (by lockdep
standards).
Actual reason we got it wrong is dated back to critical section managed by
pure flag checks, which is with us since the very beginning.

TCP sockets cannot be created with AF_UNSPEC, but
one among the supported family must be used.
Since commit 944f8b6abab6 ("selftest/net/ovpn: extend
coverage with more test cases") the default address
family for all tests was changed from AF_INET to AF_UNSPEC,
thus breaking all TCP cases.
Restore AF_INET as default address family for TCP listeners.

Upon error along the TCP data_ready event path, we have
the following chain of calls:
strp_data_ready()
ovpn_tcp_rcv()
ovpn_peer_del()

Since strp_data_ready() may be invoked from softirq context, and
ovpn_socket_release() may sleep, the above sequence may cause a

Modules linked in: ovpn(O)
This happens because the peer deletion operation reaches
ovpn_socket_release() while ovpn_sock->sock (struct socket *)
and its sk member (struct sock *) are still both valid.
Here synchronize_rcu() is invoked, after which ovpn_sock->sock->sk
becomes NULL, due to the concurrent socket closing triggered
from userspace.
After having invoked synchronize_rcu(), ovpn_socket_release() will
attempt dereferencing ovpn_sock->sock->sk, triggering the crash
reported above.
The reason for accessing sk is that we need to retrieve its
protocol and continue the cleanup routine accordingly.
This crash can be easily produced by running openvpn userspace in
client mode with `--keepalive 10 20`, while entirely omitting this
option on the server side.
After 20 seconds ovpn will assume the peer (server) to be dead,
will start removing it and will notify userspace. The latter will
receive the notification and close the transport socket, thus
triggering the crash.
To fix the race condition for good, we need to refactor struct ovpn_socket.
Since ovpn is always only interested in the sock->sk member (struct sock *)
we can directly hold a reference to it, raher than accessing it via
its struct socket container.
This means changing "struct socket *ovpn_socket->sock" to
"struct sock *ovpn_socket->sk".
While acquiring a reference to sk, we can increase its refcounter
without affecting the socket close()/destroy() notification
(which we rely on when userspace closes a socket we are using).
By increasing sk's refcounter we know we can dereference it
in ovpn_socket_release() without incurring in any race condition
anymore.
ovpn_socket_release() will ultimately decrease the reference
counter.

When deconfiguring a UDP-tunnel from a socket, we cannot
call setup_udp_tunnel_sock() with an empty config, because
this helper is expected to be invoked only during setup.
Get rid of the call to setup_udp_tunnel_sock() and just
revert what it did during socket initialization..
Note that the global udp_encap_needed_key and the GRO state
are left untouched: udp_destroy_socket() will eventually
take care of them.

UPDMEM source-mac table is a key-value map used to store devices mac
addresses according to the port identifier. UPDMEM source mac table is
used during IPv6 traffic hw acceleration since PPE entries, for space
constraints, do not contain the full source mac address but just the
identifier in the UPDMEM source-mac table.
Configure UPDMEM source-mac table with device mac addresses and set
the source-mac ID field for PPE IPv6 entries in order to select the
proper device mac address as source mac for L3 IPv6 hw accelerated traffic.

Commit 3d010c8031e3 ("udp: do not accept non-tunnel GSO skbs landing
in a tunnel") added checks in linux stack to not accept non-tunnel
GRO packets landing in a tunnel. This exposed an issue in vmxnet3
which was not correctly reporting GRO packets for tunnel packets.
This patch fixes this issue by setting correct GSO type for the
tunnel packets.
Currently, vmxnet3 does not support reporting inner fields for LRO
tunnel packets. The issue is not seen for egress drivers that do not
use skb inner fields. The workaround is to enable tnl-segmentation
offload on the egress interfaces if the driver supports it. This
problem pre-exists this patch fix and can be addressed as a separate
future patch.
