e793c724b4 can: mcp251xfd: clarify the meaning of timestamp
The mcp251xfd chip is configured to provide a timestamp with each
received and transmitted CAN frame. The timestamp is derived from the
internal free-running timer, which can also be read from the TBC
register via SPI. The timer is 32 bits wide and is clocked by the
external oscillator (typically 20 or 40 MHz).

To avoid confusion, we call this timestamp "timestamp_raw" or "ts_raw"
for short.

Using the timecounter framework, the "ts_raw" is converted to 64 bit
nanoseconds since the epoch. This is what we call "timestamp".

This is a preparation for the next patches which use the "timestamp"
to work around a bug where so far only the "ts_raw" is used.

a7801540f3 can: mcp251xfd: move mcp251xfd_timestamp_start()/stop() into mcp251xfd_chip_start/stop()
The mcp251xfd wakes up from Low Power or Sleep Mode when SPI activity
is detected. To avoid this, make sure that the timestamp worker is
stopped before shutting down the chip.

Split the starting of the timestamp worker out of
mcp251xfd_timestamp_init() into the separate function
mcp251xfd_timestamp_start().

Call mcp251xfd_timestamp_init() before mcp251xfd_chip_start(), move
mcp251xfd_timestamp_start() to mcp251xfd_chip_start(). In this way,
mcp251xfd_timestamp_stop() can be called unconditionally by
mcp251xfd_chip_stop().

94833addfa net: thunderx: Unembed netdev structure
Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].

Un-embed the net_devices from struct lmac by converting them
into pointers, and allocating them dynamically. Use the leverage
alloc_netdev() to allocate the net_device object at
bgx_lmac_enable().

The free of the device occurs at bgx_lmac_disable().

 Do not free_netdevice() if bgx_lmac_enable() fails after lmac->netdev
is allocated, since bgx_lmac_disable() is called if bgx_lmac_enable()
fails, and lmac->netdev will be freed there (similarly to lmac->dmacs).

3a158e2e8e Merge branch 'selftests-net-switch-pmtu-sh-to-use-the-internal-ovs-script'
Aaron Conole says:

====================
selftests: net: Switch pmtu.sh to use the internal ovs script.

Currently, if a user wants to run pmtu.sh and cover all the provided test
cases, they need to install the Open vSwitch userspace utilities.  This
dependency is difficult for users as well as CI environments, because the
userspace build and setup may require lots of support and devel packages
to be installed, system setup to be correct, and things like permissions
and selinux policies to be properly configured.

The kernel selftest suite includes an ovs-dpctl.py utility which can
interact with the openvswitch module directly.  This lets developers and
CI environments run without needing too many extra dependencies - just
the pyroute2 python package.

This series enhances the ovs-dpctl utility to provide support for set()
and tunnel() flow specifiers, better ipv6 handling support, and the
ability to add tunnel vports, and LWT interfaces.  Finally, it modifies
the pmtu.sh script to call the ovs-dpctl.py utility rather than the
typical OVS userspace utilities.  The pmtu.sh can still fall back on
the Open vSwitch userspace utilities if the ovs-dpctl.py script can't
be used.

b7ce46fc61 selftests: net: Use the provided dpctl rather than the vswitchd for tests.
The current pmtu test infrastucture requires an installed copy of the
ovs-vswitchd userspace.  This means that any automated or constrained
environments may not have the requisite tools to run the tests.  However,
the pmtu tests don't require any special classifier processing.  Indeed
they are only using the vswitchd in the most basic mode - as a NORMAL
switch.

However, the ovs-dpctl kernel utility can now program all the needed basic
flows to allow traffic to traverse the tunnels and provide support for at
least testing some basic pmtu scenarios.  More complicated flow pipelines
can be added to the internal ovs test infrastructure, but that is work for
the future.  For now, enable the most common cases - wide mega flows with
no other prerequisites.

Enhance the pmtu testing to try testing using the internal utility, first.
As a fallback, if the internal utility isn't running, then try with the
ovs-vswitchd userspace tools.

Additionally, make sure that when the pyroute2 package is not available
the ovs-dpctl utility will error out to properly signal an error has
occurred and skip using the internal utility.

37de65a764 selftests: openvswitch: Refactor actions parsing.
Until recently, the ovs-dpctl utility was used with a limited actions set
and didn't need to have support for multiple similar actions.  However,
when adding support for tunnels, it will be important to support multiple
set() actions in a single flow.  When printing these actions, the existing
code will be unable to print all of the sets - it will only print the
first.

Refactor this code to be easier to read and support multiple actions of the
same type in an action list.

f94ecbc920 selftests: openvswitch: Support explicit tunnel port creation.
The OVS module can operate in conjunction with various types of
tunnel ports.  These are created as either explicit tunnel vport
types, OR by creating a tunnel interface which acts as an anchor
for the lightweight tunnel support.

This patch adds the ability to add tunnel ports to an OVS
datapath for testing various scenarios with tunnel ports.  With
this addition, the vswitch "plumbing" will at least be able to
push packets around using the tunnel vports.  Future patches
will add support for setting required tunnel metadata for lwts
in the datapath.  The end goal will be to push packets via these
tunnels, and will be used in an upcoming commit for testing the
path MTU.

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.

  #  RUN           msg_oob.no_peek.inline_oob_ahead_break ...

  #            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 ...

36893ef0b6 af_unix: Don't stop recv() at consumed ex-OOB skb.
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.

Without fix:

  #  RUN           msg_oob.no_peek.ex_oob_ahead_break ...
  # msg_oob.c:138:ex_oob_ahead_break:AF_UNIX :hellowo

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

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

93c99f21db af_unix: Don't stop recv(MSG_DONTWAIT) if consumed OOB skb is at the head.
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
  not ok 8 msg_oob.no_peek.ex_oob_break

With fix:

  #  RUN           msg_oob.no_peek.ex_oob_break ...
  #            OK  msg_oob.no_peek.ex_oob_break

b94038d841 af_unix: Stop recv(MSG_PEEK) at consumed OOB skb.
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
  # msg_oob.c:137:oob_ahead_break:Expected ret[0] (9) == expected_len (4)
  # oob_ahead_break: Test terminated by assertion
  #          FAIL  msg_oob.peek.oob_ahead_break
  not ok 13 msg_oob.peek.oob_ahead_break

With fix:

  #  RUN           msg_oob.peek.oob_ahead_break ...
  #            OK  msg_oob.peek.oob_ahead_break
  ok 13 msg_oob.peek.oob_ahead_break

d098d77232 selftest: af_unix: Add msg_oob.c.
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.

7d139181a8 selftest: af_unix: Remove test_unix_oob.c.
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.

bab4923132 tracing/net_sched: NULL pointer dereference in perf_trace_qdisc_reset()
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 51270d573a. 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.

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.

====================
selftests: drv-net: rss_ctx: add tests for RSS contexts

Add a few tests exercising RSS context API.
In addition to basic sanity checks, tests add RSS contexts,
n-tuple rule to direct traffic to them (based on dst port),
and qstats to make sure traffic landed where we expected.

v2 adds a test for removing contexts out of order. When testing
bnxt - either the new test or running more tests after the overlap
test makes the device act strangely. To the point where it may start
giving out ntuple IDs of 0 for all rules..

creating extra RSS contexts in drivers which support it.

Note that rss_ctx.test_rss_context_out_of_order fails with the device
I tested with, but it seems to be a device / driver bug.

Teach the load generator how to wait for at least given number
of packets to be received. This will be useful for filtering
where we'll want to send a non-trivial number of packets and
make sure they landed in right queues.

this leads to occasional failures. Try to check if port is
already in use by opening a socket and binding to that port.
