Pull firewire fix from Takashi Sakamoto:
"After merging a commit 1fffe7a34c89 ("script: modpost: emit a warning
when the description is missing"), MODULE_DESCRIPTOR seems to be
mandatory for kernel modules. In FireWire subsystem, the most of
practical kernel modules have the field, while KUnit test modules do
not. A single patch is applied to fix them"

TCP_CLOSE may or may not have current/rnext keys and should not be
considered "established". The fast-path for TCP_CLOSE is
SKB_DROP_REASON_TCP_CLOSE. This is what tcp_rcv_state_process() does
anyways. Add an early drop path to not spend any time verifying
segment signatures for sockets in TCP_CLOSE state.

Currently NCSI driver will send several NCSI commands back to back without
waiting the response of previous NCSI command or timeout in some state
when NIC have multi channel. This operation against the single thread
manner defined by NCSI SPEC(section 6.3.2.3 in DSP0222_1.1.1)
According to NCSI SPEC(section 6.2.13.1 in DSP0222_1.1.1), we should probe
one channel at a time by sending NCSI commands (Clear initial state, Get
version ID, Get capabilities...), than repeat this steps until the max
number of channels which we got from NCSI command (Get capabilities) has
been probed.

John Sperbeck reported that if we turn off CONFIG_RFS_ACCEL, the 'head'

The object "ax25_dev" is managed by reference counting. Thus it should
not be directly released by kfree(), replace with ax25_dev_put().

When releasing a socket in ax25_release(), we call netdev_put() to
decrease the refcount on the associated ax.25 device. However, the
execution path for accepting an incoming connection never calls
netdev_hold(). This imbalance leads to refcount errors, and ultimately
to kernel crashes.
A typical call trace for the above situation will start with one of the
following errors:
refcount_t: decrement hit 0; leaking memory.
refcount_t: underflow; use-after-free.
And will then have a trace like:
Call Trace:

On reboot (or any attempt to remove the interface), the kernel gets
stuck in an infinite loop:
unregister_netdevice: waiting for ax0 to become free. Usage count = 0
This patch corrects these issues by ensuring that we call netdev_hold()
and ax25_dev_hold() for new connections in ax25_accept(). This makes the
logic leading to ax25_accept() match the logic for ax25_bind(): in both
cases we increment the refcount, which is ultimately decremented in
ax25_release().

When the following snippet is run, lockdep will report a deadlock[1].
/* Acquire all queues dim_locks */
for (i = 0; i < vi->max_queue_pairs; i++)
mutex_lock(&vi->rq[i].dim_lock);
There's no deadlock here because the vq locks are always taken
in the same order, but lockdep can not figure it out. So refactoring
the code to alleviate the problem.

When the dim worker is scheduled, if it no longer needs to issue
commands, dim may not be able to return to the working state later.
For example, the following single queue scenario:
1. The dim worker of rxq0 is scheduled, and the dim status is
changed to DIM_APPLY_NEW_PROFILE;
2. dim is disabled or parameters have not been modified;
3. virtnet_rx_dim_work exits directly;
Then, even if net_dim is invoked again, it cannot work because the
state is not restored to DIM_START_MEASURE.

because the request is marked forced ASYNC and has a bad file fd, and
hence takes the forced async prep path.
Current kernels with the request async prep cleaned up can no longer hit
this issue, but for ease of backporting, let's add this safety check in
here too as it really doesn't hurt. For both cases, this will inevitably
end with a CQE posted with -EBADF.

rtlwifi relied on ~0 in order to ignore the default retry limits of

RTL8192DU has a lot of packet loss with the default limits from

Commit f236464f1db7 ("wifi: wilc1000: convert list management to RCU")
attempted to convert SRCU to RCU usage, assuming it was not really needed.
The runtime issues that arose after merging it showed that there are code
paths involving sleeping functions, and removing those would need some
heavier driver rework.
Add some documentation about SRCU need to make sure that any future
developer do not miss some use cases if tempted to convert back again to
RCU.

Commit f236464f1db7 ("wifi: wilc1000: convert list management to RCU")
replaced SRCU with RCU, aiming to simplify RCU usage in the driver. No
documentation or commit history hinted about why SRCU has been preferred
in original design, so it has been assumed to be safe to do this
conversion.
Unfortunately, some static analyzers raised warnings, confirmed by runtime
checker, not long after the merge. At least three different issues arose
when switching to RCU:
- wilc_wlan_txq_filter_dup_tcp_ack is executed in a RCU read critical
section yet calls wait_for_completion_timeout
- wilc_wfi_init_mon_interface calls kmalloc and register_netdevice while
manipulating a vif retrieved from vif list
- set_channel sends command to chip (and so, also waits for a completion)
while holding a vif retrieved from vif list (so, in RCU read critical
section)
Some of those issues are not trivial to fix and would need bigger driver
rework. Fix those issues by reverting the SRCU to RCU conversion commit

This reverts commit 8c467f3300591a206fa8dcc6988d768910799872.
Turns out this breaks many architectures as the vt ioctls do not all
match up everywhere due to historical reasons, so the original commit is
invalid for many values.

The bpf_session_cookie is unavailable for !CONFIG_FPROBE as reported
by Sebastian [1].
To fix that we remove CONFIG_FPROBE ifdef for session kfuncs, which
is fine, because there's filter for session programs.
Then based on bpf_trace.o dependency:
obj-$(CONFIG_BPF_EVENTS) += bpf_trace.o
we add bpf_session_cookie BTF_ID in special_kfunc_set list dependency
on CONFIG_BPF_EVENTS.

When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...clang issues this warning:
futex_requeue_pi.c:403:17: warning: passing 'const char **' to parameter
of type 'char **' discards qualifiers in nested pointer types
[-Wincompatible-pointer-types-discards-qualifiers]
This warning fires because test_name is passed into asprintf(3), which
then changes it.
Fix this by simply removing the const qualifier. This is a local
automatic variable in a very short function, so there is not much need
to use the compiler to enforce const-ness at this scope.

In some scenarios, if too many commands are issued by nvme command in
the same time by user tasks, this may exhaust all tags of admin_q. If
a reset (nvme reset or IO timeout) occurs before these commands finish,
reconnect routine may fail to update nvme regs due to insufficient tags,
which will cause kernel hang forever. In order to workaround this issue,
maybe we can let reg_read32()/reg_read64()/reg_write32() use reserved
tags. This maybe safe for nvmf:
1. For the disable ctrl path, we will not issue connect command
2. For the enable ctrl / fw activate path, since connect and reg_xx()
are called serially.
So the reserved tags may still be enough while reg_xx() use reserved tags.

Intel CPUs have a MSR bit to limit CPUID enumeration to leaf two. If
this bit is set by the BIOS then CPUID evaluation including topology
enumeration does not work correctly as the evaluation code does not try
to analyze any leaf greater than two.
This went unnoticed before because the original topology code just
repeated evaluation several times and managed to overwrite the initial
limited information with the correct one later. The new evaluation code
does it once and therefore ends up with the limited and wrong
information.
Cure this by unlocking CPUID right before evaluating anything which
depends on the maximum CPUID leaf being greater than two instead of
rereading stuff after unlock.

The prior strscpy() replacement of strncpy() here expected the
manufacture_reply strings to be NUL-terminated, but it is possible
they are not, as the code pattern here shows, e.g., edev->vendor_id
being exactly 1 character larger than manufacture_reply->vendor_id,
and the replaced strncpy() was copying only up to the size of the
source character array. Replace this with memtostr(), which is the
unambiguous way to convert a maybe not-NUL-terminated character array
into a NUL-terminated string.
