Fix UBSAN warnings that occur when using a system with 32 physical
cpu cores or more, or when the user defines a number of Ethernet
queues greater than or equal to FP_SB_MAX_E1x using the num_queues
module parameter.

Currently there is a read/write out of bounds that occurs on the array
"struct stats_query_entry query" present inside the "bnx2x_fw_stats_req"
struct in "drivers/net/ethernet/broadcom/bnx2x/bnx2x.h".
Looking at the definition of the "struct stats_query_entry query" array:

struct stats_query_entry query[FP_SB_MAX_E1x+
         BNX2X_FIRST_QUEUE_QUERY_IDX];

FP_SB_MAX_E1x is defined as the maximum number of fast path interrupts and
has a value of 16, while BNX2X_FIRST_QUEUE_QUERY_IDX has a value of 3
meaning the array has a total size of 19.
Since accesses to "struct stats_query_entry query" are offset-ted by
BNX2X_FIRST_QUEUE_QUERY_IDX, that means that the total number of Ethernet
queues should not exceed FP_SB_MAX_E1x (16). However one of these queues
is reserved for FCOE and thus the number of Ethernet queues should be set
to [FP_SB_MAX_E1x -1] (15) if FCOE is enabled or [FP_SB_MAX_E1x] (16) if
it is not.

This is also described in a comment in the source code in
drivers/net/ethernet/broadcom/bnx2x/bnx2x.h just above the Macro definition
of FP_SB_MAX_E1x. Below is the part of this explanation that it important
for this patch

/*
  * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is
  * control by the number of fast-path status blocks supported by the
  * device (HW/FW). Each fast-path status block (FP-SB) aka non-default
  * status block represents an independent interrupts context that can
  * serve a regular L2 networking queue. However special L2 queues such
  * as the FCoE queue do not require a FP-SB and other components like
  * the CNIC may consume FP-SB reducing the number of possible L2 queues
  *
  * If the maximum number of FP-SB available is X then:
  * a. If CNIC is supported it consumes 1 FP-SB thus the max number of
  *    regular L2 queues is Y=X-1
  * b. In MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
  * c. If the FCoE L2 queue is supported the actual number of L2 queues
  *    is Y+1
  * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
  *    slow-path interrupts) or Y+2 if CNIC is supported (one additional
  *    FP interrupt context for the CNIC).
  * e. The number of HW context (CID count) is always X or X+1 if FCoE
  *    L2 queue is supported. The cid for the FCoE L2 queue is always X.
  */

However this driver also supports NICs that use the E2 controller which can
handle more queues due to having more FP-SB represented by FP_SB_MAX_E2.
Looking at the commits when the E2 support was added, it was originally
using the E1x parameters: commit f2e0899f ("bnx2x: Add 57712 support").
Back then FP_SB_MAX_E2 was set to 16 the same as E1x. However the driver
was later updated to take full advantage of the E2 instead of having it be
limited to the capabilities of the E1x. But as far as we can tell, the
array "stats_query_entry query" was still limited to using the FP-SB
available to the E1x cards as part of an oversignt when the driver was
updated to take full advantage of the E2, and now with the driver being
aware of the greater queue size supported by E2 NICs, it causes the UBSAN
warnings seen in the stack traces below.

This patch increases the size of the "stats_query_entry query" array by
replacing FP_SB_MAX_E1x with FP_SB_MAX_E2 to be large enough to handle
both types of NICs.

ConnectX devices lack ability to count payload data byte size which is
needed for SA to return to libreswan for rekeying.

As a solution let's approximate that by decreasing headers size from
total size counted by flow steering. The calculation doesn't take into
account any other headers which can be in the packet (e.g. IP extensions).

Currently, ingress acl is used for three features. It is created only
when vport metadata match and prio tag are enabled. But active-backup
lag mode also uses it. It is independent of vport metadata match and
prio tag. And vport metadata match can be disabled using the
following devlink command:

 # devlink dev param set pci/0000:08:00.0 name esw_port_metadata \
	value false cmode runtime

If ingress acl is not created, will hit panic when creating drop rule
for active-backup lag mode. If always create it, there will be about
5% performance degradation.

Fix it by creating ingress acl when needed. If esw_port_metadata is
true, ingress acl exists, then create drop rule using existing
ingress acl. If esw_port_metadata is false, create ingress acl and
then create drop rule.

In some production workloads we noticed that connections could
sometimes close extremely prematurely with ETIMEDOUT after
transmitting only 1 TLP and RTO retransmission (when we would normally
expect roughly tcp_retries2 = TCP_RETR2 = 15 RTOs before a connection
closes with ETIMEDOUT).

From tracing we determined that these workloads can suffer from a
scenario where in fast recovery, after some retransmits, a DSACK undo
can happen at a point where the scoreboard is totally clear (we have
retrans_out == sacked_out == lost_out == 0). In such cases, calling
tcp_try_keep_open() means that we do not execute any code path that
clears tp->retrans_stamp to 0. That means that tp->retrans_stamp can
remain erroneously set to the start time of the undone fast recovery,
even after the fast recovery is undone. If minutes or hours elapse,
and then a TLP/RTO/RTO sequence occurs, then the start_ts value in
retransmits_timed_out() (which is from tp->retrans_stamp) will be
erroneously ancient (left over from the fast recovery undone via
DSACKs). Thus this ancient tp->retrans_stamp value can cause the
connection to die very prematurely with ETIMEDOUT via
tcp_write_err().

The fix: we change DSACK undo in fast recovery (TCP_CA_Recovery) to
call tcp_try_to_open() instead of tcp_try_keep_open(). This ensures
that if no retransmits are in flight at the time of DSACK undo in fast
recovery then we properly zero retrans_stamp. Note that calling
tcp_try_to_open() is more consistent with other loss recovery
behavior, since normal fast recovery (CA_Recovery) and RTO recovery
(CA_Loss) both normally end when tp->snd_una meets or exceeds
tp->high_seq and then in tcp_fastretrans_alert() the "default" switch
case executes tcp_try_to_open(). Also note that by inspection this
change to call tcp_try_to_open() implies at least one other nice bug
fix, where now an ECE-marked DSACK that causes an undo will properly
invoke tcp_enter_cwr() rather than ignoring the ECE mark.

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 auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), callback function adev_release
calls kfree(madev). We shouldn't call kfree(madev) again
in the error handling path. Set 'madev' to NULL.

====================
af_unix: Fix bunch of MSG_OOB bugs and add new tests.

This series rewrites the selftest for AF_UNIX MSG_OOB and fixes
bunch of bugs that AF_UNIX behaves differently compared to TCP.

Note that the test discovered few more bugs in TCP side, which
will be fixed in another series.

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.

  #  RUN           msg_oob.no_peek.inline_oob_ahead_break ...
  # msg_oob.c:146:inline_oob_ahead_break:AF_UNIX :world

  #            OK  msg_oob.no_peek.inline_oob_ahead_break
  ok 14 msg_oob.no_peek.inline_oob_ahead_break

  2) The head OOB data is dropped if SO_OOBINLINE is disabled
     if a new OOB data is queued.

  #  RUN           msg_oob.no_peek.inline_ex_oob_drop ...

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
OOB data if the old OOB data is at the head of recvq.

  #  RUN           msg_oob.no_peek.ex_oob_drop ...
  # msg_oob.c:146:ex_oob_drop:AF_UNIX :x
  # msg_oob.c:147:ex_oob_drop:TCP     :Resource temporarily unavailable

  # msg_oob.c:147:ex_oob_drop:TCP     :Invalid argument
  #            OK  msg_oob.no_peek.ex_oob_drop
  ok 9 msg_oob.no_peek.ex_oob_drop

  #  RUN           msg_oob.no_peek.ex_oob_drop_2 ...
  # msg_oob.c:146:ex_oob_drop_2:AF_UNIX :x
  # msg_oob.c:147:ex_oob_drop_2:TCP     :Resource temporarily unavailable
  #            OK  msg_oob.no_peek.ex_oob_drop_2

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

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().

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.

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.

[ 5301.597057] Bye!

After applying our patch, I didn't find any kernel panic errors.

We've found a simple reproducer

 # echo 1 > /sys/kernel/debug/tracing/events/qdisc/qdisc_reset/enable

 # ip link add veth0 type veth peer name veth1

 Error: Unknown device type.

However, without our patch applied, I tested upstream 6.10.0-rc3 kernel
using the qdisc_reset event and the ip command on my qemu virtual machine.

This 2 commands makes always kernel panic.

Linux version: 6.10.0-rc3

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.

We got sad news that Larry is not with us anymore. He was a long time
Linux developer, his first commit was back in 2005 and he has
maintained several wireless drivers over the years. He was known for
patiently supporting Linux users with all sorts of problems they had.
Larry's work helped so many people around the world and I always
enjoyed working with him, even though I sadly never met him.

Rest in Peace, Larry. You will be missed.
