6fe7de5e9c tools/net/ynl: Fix c codegen for array-nest
ynl-gen-c generates e.g. 'calloc(mcast_groups, sizeof(*dst->mcast_groups))'
for array-nest attrs when it should be 'n_mcast_groups'.

Add a 'n_' prefix in the generated code for array-nests.

771b7012e5 tools/net/ynl: Report netlink errors without stacktrace
ynl does not handle NlError exceptions so they get reported like program
failures. Handle the NlError exceptions and report the netlink errors
more cleanly.

Example now:

Netlink error: No such file or directory
nl_len = 44 (28) nl_flags = 0x300 nl_type = 2
	error: -2	extack: {'bad-attr': '.op'}

Example before:

Traceback (most recent call last):
  File "/home/donaldh/net-next/./tools/net/ynl/cli.py", line 81, in <module>
    main()
  File "/home/donaldh/net-next/./tools/net/ynl/cli.py", line 69, in main
    reply = ynl.dump(args.dump, attrs)
            ^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/donaldh/net-next/tools/net/ynl/lib/ynl.py", line 906, in dump
    return self._op(method, vals, [], dump=True)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

cecbc52c46 tools/net/ynl: Fix extack decoding for netlink-raw
Extack decoding was using a hard-coded msg header size of 20 but
netlink-raw has a header size of 16.

Use a protocol specific msghdr_size() when decoding the attr offssets.

12fbd67ea3 isdn: capi: make capi_class constant
Since commit 43a7206b09 ("driver core: class: make class_register() take
a const *"), the driver core allows for struct class to be in read-only
memory, so move the capi_class structure to be declared at build time
placing it into read-only memory, instead of having to be dynamically

15d2540e0d tools: ynl: check for overflow of constructed messages
Donald points out that we don't check for overflows.
Stash the length of the message on nlmsg_pid (nlmsg_seq would
do as well). This allows the attribute helpers to remain
self-contained (no extra arguments). Also let the put
helpers continue to return nothing. The error is checked
only in (newly introduced) ynl_msg_end().

====================
tcp: add two missing addresses when using trace

When I reviewed other people's patch [1], I noticed that similar things
also happen in tcp_event_skb class and tcp_event_sk_skb class. They
don't print those two addrs of skb/sk which already exist.

In this patch, I just do as other trace functions do, like
trace_net_dev_start_xmit(), to know the exact flow or skb we would like
to know in case some systems doesn't support BPF programs well or we
have to use /sys/kernel/debug/tracing only for some reasons.

Here's a V3 for an update on the phylink porting guide. The only

The main point of the update is the description of a basic process to
follow to expose one or more PCS to phylink. Let me know if you spot any

The second patch is a simple fixup on some in-code doc that was spotted

====================
Netfilter fixes for net

The following patchset contains fixes for net:

Patch #1 disallows anonymous sets with timeout, except for dynamic sets.
         Anonymous sets with timeouts using the pipapo set backend makes
         no sense from userspace perspective.

Patch #2 rejects constant sets with timeout which has no practical usecase.
         This kind of set, once bound, contains elements that expire but
         no new elements can be added.

Patch #3 restores custom conntrack expectations with NFPROTO_INET,
         from Florian Westphal.

Patch #4 marks rhashtable anonymous set with timeout as dead from the
         commit path to avoid that async GC collects these elements. Rules
         that refers to the anonymous set get released with no mutex held
         from the commit path.

Patch #5 fixes a UBSAN shift overflow in H.323 conntrack helper,
         from Lena Wang.

netrom: Fix all the data-races around sysctls

As the title said, in this patchset I fix the data-race issues because
the writer and the reader can manipulate the same value concurrently.

c223416198 mlxbf_gige: add support to display pause frame counters
This patch updates the mlxbf_gige driver to support the
"get_pause_stats()" callback, which enables display of
pause frame counters via "ethtool -I -a oob_net0".

The pause frame counters are only enabled if the "counters_en"
bit is asserted in the LLU general config register. The driver
will only report stats, and thus overwrite the default stats
state of ETHTOOL_STAT_NOT_SET, if "counters_en" is asserted.

1677293ed8 net: phy: qca807x: fix compilation when CONFIG_GPIOLIB is not set
Kernel bot has discovered that if CONFIG_GPIOLIB is not set compilation
will fail.

Upon investigation the issue is that qca807x_gpio() is guarded by a
preprocessor check but then it is called under
if (IS_ENABLED(CONFIG_GPIOLIB)) in the probe call so the compiler will
error out since qca807x_gpio() has not been declared if CONFIG_GPIOLIB has
not been set.

Commit 3e2f544dd8 ("net: get stats64 if device if driver is

unless the driver is doing some custom stats collection, it does not
need to set .ndo_get_stats64.

41cca0542d selftests/harness: Fix TEST_F()'s vfork handling
Always run fixture setup in the grandchild process, and by default also
run the teardown in the same process.  However, this change makes it
possible to run the teardown in a parent process when
_metadata->teardown_parent is set to true (e.g. in fixture setup).

Fix TEST_SIGNAL() by forwarding grandchild's signal to its parent.  Fix
seccomp tests by running the test setup in the parent of the test
thread, as expected by the related test code.  Fix Landlock tests by
waiting for the grandchild before processing _metadata.

Use of exit(3) in tests should be OK because the environment in which
the vfork(2) call happen is already dedicated to the running test (with
flushed stdio, setpgrp() call), see __run_test() and the call to fork(2)
just before running the setup/test/teardown.  Even if the test
configures its own exit handlers, they will not be run by the parent
because it never calls exit(3), and the test function either ends with a
call to _exit(2) or a signal.

- Patch 1 drops duplicated header inclusions.

- Patch 2 updates PM 'set_flags' interface, to make it more similar to
  others.

- Patch 3 adds some error messages for the PM 'set_flags' command to
  help the userspace understanding what's wrong in case of error.

- Patch 4 simplifies __lookup_addr() function from pm_netlink.c.

Except for the 3rd patch, the behaviour is not supposed to be modified.

as __lookup_addr_by_id(), it can be replaced by __lookup_addr_by_id()
directly. So drop this parameter, let __lookup_addr() only looks up address
on the local address list by comparing addresses in it, not address ids.
