Commit 78464d76 ("tools/power turbostat: Add columns for clustered
uncore frequency") introduced 'probe_intel_uncore_frequency_cluster()'
in a way which prevents printing uncore frequency columns if either of
the '-q' or '-l' options are used. Systems which do not have multiple
uncore frequencies per package are unaffected by this regression.

Fix the function so that uncore frequency columns are shown when either
the '-l' or '-q' option is used by checking if 'quiet' is true after
adding counters for the uncore frequency columns.

In some cases specifying the '-n' command line argument will cause
turbostat to fail.  For instance 'turbostat -n 1' works fine; however,
'turbostat -n 1 -d' will fail.  This is the result of the first call
to getopt_long_only() where "MP" is specified as the optstring.  This can
be easily fixed by changing the optstring from "MP" to "MPn:" to remove
ambiguity between the arguments.

filp->pid is supposed to be a refcounted pointer; however, before this
patch, drm_file_update_pid() only increments the refcount of a struct
pid after storing a pointer to it in filp->pid and dropping the
dev->filelist_mutex, making the following race possible:

process A               process B
=========               =========
                        begin drm_file_update_pid
                        mutex_lock(&dev->filelist_mutex)
                        rcu_replace_pointer(filp->pid, <pid B>, 1)
                        mutex_unlock(&dev->filelist_mutex)
begin drm_file_update_pid
mutex_lock(&dev->filelist_mutex)
rcu_replace_pointer(filp->pid, <pid A>, 1)
mutex_unlock(&dev->filelist_mutex)
get_pid(<pid A>)
synchronize_rcu()
put_pid(<pid B>)   *** pid B reaches refcount 0 and is freed here ***
                        get_pid(<pid B>)   *** UAF ***
                        synchronize_rcu()
                        put_pid(<pid A>)

As far as I know, this race can only occur with CONFIG_PREEMPT_RCU=y
because it requires RCU to detect a quiescent state in code that is not
explicitly calling into the scheduler.

This race leads to use-after-free of a "struct pid".
It is probably somewhat hard to hit because process A has to pass
through a synchronize_rcu() operation while process B is between
mutex_unlock() and get_pid().

Fix it by ensuring that by the time a pointer to the current task's pid
is stored in the file, an extra reference to the pid has been taken.

This fix also removes the condition for synchronize_rcu(); I think
that optimization is unnecessary complexity, since in that case we
would usually have bailed out on the lockless check above.

Building with W=1 in some configurations produces a false positive
warning for kallsyms:

kernel/kallsyms.c: In function '__sprint_symbol.isra':
kernel/kallsyms.c:503:17: error: 'strcpy' source argument is the same as destination [-Werror=restrict]
  503 |                 strcpy(buffer, name);
      |                 ^~~~~~~~~~~~~~~~~~~~

This originally showed up while building with -O3, but later started
happening in other configurations as well, depending on inlining
decisions. The underlying issue is that the local 'name' variable is
always initialized to the be the same as 'buffer' in the called functions
that fill the buffer, which gcc notices while inlining, though it could
see that the address check always skips the copy.

The calling conventions here are rather unusual, as all of the internal
lookup functions (bpf_address_lookup, ftrace_mod_address_lookup,
ftrace_func_address_lookup, module_address_lookup and
kallsyms_lookup_buildid) already use the provided buffer and either return
the address of that buffer to indicate success, or NULL for failure,
but the callers are written to also expect an arbitrary other buffer
to be returned.

Rework the calling conventions to return the length of the filled buffer
instead of its address, which is simpler and easier to follow as well
as avoiding the warning. Leave only the kallsyms_lookup() calling conventions
unchanged, since that is called from 16 different functions and
adapting this would be a much bigger change.

Netfilter fixes for net

The following patchset contains two Netfilter fixes for net:

Patch #1 fixes CONFIG_SYSCTL=n for a patch coming in the previous PR
	 to move the sysctl toggle to enable SRv6 netfilter hooks from
	 nf_conntrack to the core, from Jianguo Wu.

Patch #2 fixes a possible pointer leak to userspace due to insufficient
	 validation of NFT_DATA_VALUE.

Linus found this pointer leak to userspace via zdi-disclosures@ and
forwarded the notice to Netfilter maintainers, he appears as reporter
because whoever found this issue never approached Netfilter
maintainers neither via security@ nor in private.

When SO_OOBINLINE is enabled on a socket, MSG_OOB can be recv()ed
without MSG_OOB flag, and ioctl(SIOCATMARK) will behaves differently.

This patch adds some test cases for SO_OOBINLINE.

Note the new test cases found two bugs in TCP.

  1) After reading OOB data with non-inline mode, we can re-read
     the data by setting SO_OOBINLINE.

Currently, recv() is stopped at a consumed OOB skb even if a new
OOB skb is queued and we can ignore the old OOB skb.

  >>> from socket import *
  >>> c1, c2 = socket(AF_UNIX, SOCK_STREAM)
  >>> c1.send(b'hellowor', MSG_OOB)
  8
  >>> c2.recv(1, MSG_OOB)  # consume OOB data stays at middle of recvq.
  b'r'
  >>> c1.send(b'ld', MSG_OOB)
  2
  >>> c2.recv(10)          # recv() stops at the old consumed OOB
  b'hellowo'               # should be 'hellowol'

manage_oob() should not stop recv() at the old consumed OOB skb if
there is a new OOB data queued.

Note that TCP behaviour is apparently wrong in this test case because
we can recv() the same OOB data twice.

While testing, I found some weird behaviour on the TCP side as well.

For example, TCP drops the preceding OOB data when queueing a new

This patch allows AF_UNIX's MSG_OOB implementation to produce different
results from TCP when operations are guarded with tcp_incompliant{}.

Let's say a socket send()s "hello" with MSG_OOB and "world" without flags,

  >>> from socket import *
  >>> c1, c2 = socketpair(AF_UNIX)
  >>> c1.send(b'hello', MSG_OOB)
  5
  >>> c1.send(b'world')
  5

and its peer recv()s "hell" and "o".

  >>> c2.recv(10)
  b'hell'
  >>> c2.recv(1, MSG_OOB)
  b'o'

Now the consumed OOB skb stays at the head of recvq to return a correct
value for ioctl(SIOCATMARK), which is broken now and fixed by a later
patch.

Then, if peer issues recv() with MSG_DONTWAIT, manage_oob() returns NULL,
so recv() ends up with -EAGAIN.

  >>> c2.setblocking(False)  # This causes -EAGAIN even with available data
  >>> c2.recv(5)
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  BlockingIOError: [Errno 11] Resource temporarily unavailable

However, next recv() will return the following available data, "world".

  >>> c2.recv(5)
  b'world'

When the consumed OOB skb is at the head of the queue, we need to fetch
the next skb to fix the weird behaviour.

Note that the issue does not happen without MSG_DONTWAIT because we can
retry after manage_oob().

This patch also adds a test case that covers the issue.

Without fix:

  #  RUN           msg_oob.no_peek.ex_oob_break ...
  # msg_oob.c:134:ex_oob_break:AF_UNIX :Resource temporarily unavailable
  # msg_oob.c:135:ex_oob_break:Expected:ld

  # ex_oob_break: Test terminated by assertion
  #          FAIL  msg_oob.no_peek.ex_oob_break

  #            OK  msg_oob.no_peek.ex_oob_break

After consuming OOB data, recv() reading the preceding data must break at
the OOB skb regardless of MSG_PEEK.

Currently, MSG_PEEK does not stop recv() for AF_UNIX, and the behaviour is
not compliant with TCP.

  >>> from socket import *
  >>> c1, c2 = socketpair(AF_UNIX)
  >>> c1.send(b'hello', MSG_OOB)
  5
  >>> c1.send(b'world')
  5
  >>> c2.recv(1, MSG_OOB)
  b'o'
  >>> c2.recv(9, MSG_PEEK)  # This should return b'hell'
  b'hellworld'              # even with enough buffer.

Let's fix it by returning NULL for consumed skb and unlinking it only if
MSG_PEEK is not specified.

This patch also adds test cases that add recv(MSG_PEEK) before each recv().

Without fix:

  #  RUN           msg_oob.peek.oob_ahead_break ...
  # msg_oob.c:134:oob_ahead_break:AF_UNIX :hellworld
  # msg_oob.c:135:oob_ahead_break:Expected:hell

AF_UNIX's MSG_OOB functionality lacked thorough testing, and we found
some bizarre behaviour.

The new selftest validates every MSG_OOB operation against TCP as a
reference implementation.

This patch adds only a few tests with basic send() and recv() that
do not fail.

The following patches will add more test cases for SO_OOBINLINE, SIGURG,
EPOLLPRI, and SIOCATMARK.

test_unix_oob.c does not fully cover AF_UNIX's MSG_OOB functionality,
thus there are discrepancies between TCP behaviour.

Also, the test uses fork() to create message producer, and it's not
easy to understand and add more test cases.

Let's remove test_unix_oob.c and rewrite a new test.

In the TRACE_EVENT(qdisc_reset) NULL dereference occurred from

 qdisc->dev_queue->dev <NULL> ->name

This situation simulated from bunch of veths and Bluetooth disconnection
and reconnection.

During qdisc initialization, qdisc was being set to noop_queue.
In veth_init_queue, the initial tx_num was reduced back to one,
causing the qdisc reset to be called with noop, which led to the kernel
panic.

I've attached the GitHub gist link that C converted syz-execprogram
source code and 3 log of reproduced vmcore-dmesg.

 https://gist.github.com/yskelg/cc64562873ce249cdd0d5a358b77d740

Yeoreum and I use two fuzzing tool simultaneously.

One process with syz-executor : https://github.com/google/syzkaller

 $ ./syz-execprog -executor=./syz-executor -repeat=1 -sandbox=setuid \
    -enable=none -collide=false log1

The other process with perf fuzzer:
 https://github.com/deater/perf_event_tests/tree/master/fuzzer

 $ perf_event_tests/fuzzer/perf_fuzzer

I think this will happen on the kernel version.

 Linux kernel version +v6.7.10, +v6.8, +v6.9 and it could happen in v6.10.

This occurred from 51270d57. I think this patch is absolutely
necessary. Previously, It was showing not intended string value of name.

I've reproduced 3 time from my fedora 40 Debug Kernel with any other module
or patched.

However, without our patch applied, I tested upstream 6.10.0-rc3 kernel

This 2 commands makes always kernel panic.

Yeoreum and I don't know if the patch we wrote will fix the underlying
cause, but we think that priority is to prevent kernel panic happening.
So, we're sending this patch.

register store validation for NFT_DATA_VALUE is conditional, however,
the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This
only requires a new helper function to infer the register type from the
set datatype so this conditional check can be removed. Otherwise,
pointer to chain object can be leaked through the registers.

ASoC: Fixes for v6.10

A relatively large batch of updates, largely due to the long interval
since I last sent fixes due to various travel and holidays.  There's a
lot of driver specific fixes and quirks in here, none of them too major,
and also some fixes for recently introduced memory safety issues in the
topology code.

Modify register setting sequence of enabling inline command
to fix issue of random interrupt from push-button.

The conversion of SPP to MIDI2 UMP called a wrong function, and the
secondary argument wasn't taken.  As a result, MSB of SPP was always
zero.  Fix to call the right function.
