We've added 8 non-merge commits during the last 13 day(s) which contain
a total of 21 files changed, 238 insertions(+), 161 deletions(-).

The main changes are:

1) Fix verification issues in some BPF programs due to their stack usage
   patterns, from Eduard Zingerman.

2) Fix to add missing overflow checks in xdp_umem_reg and return an error
   in such case, from Kal Conley.

3) Fix and undo poisoning of strlcpy in libbpf given it broke builds for
   libcs which provided the former like uClibc-ng, from Jesus Sanchez-Palencia.

4) Fix insufficient bpf_jit_limit default to avoid users running into hard
   to debug seccomp BPF errors, from Daniel Borkmann.

5) Fix driver return code when they don't support a bpf_xdp_metadata kfunc
   to make it unambiguous from other errors, from Jesper Dangaard Brouer.

6) Two BPF selftest fixes to address compilation errors from recent changes
   in kernel structures, from Alexei Starovoitov.

Masami Hiramatsu (Google) b69245126a bootconfig: Fix testcase to increase max node
Since commit 6c40624930 ("bootconfig: Increase max nodes of bootconfig
from 1024 to 8192 for DCC support") increased the max number of bootconfig
node to 8192, the bootconfig testcase of the max number of nodes fails.
To fix this issue, we can not simply increase the number in the test script
because the test bootconfig file becomes too big (>32KB). To fix that, we
can use a combination of three alphabets (26^3 = 17576). But with that,
we can not express the 8193 (just one exceed from the limitation) because
it also exceeds the max size of bootconfig. So, the first 26 nodes will just
use one alphabet.

With this fix, test-bootconfig.sh passes all tests.

Nikolay Aleksandrov 222c94ec0a selftests: bonding: add tests for ether type changes
Add new network selftests for the bonding device which exercise the ether
type changing call paths. They also test for the recent syzbot bug[1] which
causes a warning and results in wrong device flags (IFF_SLAVE missing).
The test adds three bond devices and a nlmon device, enslaves one of the
bond devices to the other and then uses the nlmon device for successful
and unsuccesful enslaves both of which change the bond ether type. Thus
we can test for both MASTER and SLAVE flags at the same time.

If the flags are properly restored we get:
TEST: Change ether type of an enslaved bond device with unsuccessful enslave   [ OK ]
TEST: Change ether type of an enslaved bond device with successful enslave   [ OK ]

Jakub Kicinski cfab77c0b5 ynl: make the tooling check the license
The (only recently documented) expectation is that all specs

What's worse we then go ahead and assume the license was right,
outputting the expected license into generated files.

I relicensed Netlink spec code to GPL-2.0 OR BSD-3-Clause but
we still put a slightly different license on the uAPI header
than the rest of the code. Use the Linux-syscall-note on all
the specs and all generated code. It's moot for kernel code,
but should not hurt. This way the licenses match everywhere.

Po-Hsu Lin 24994513ad selftests: net: devlink_port_split.py: skip test if no suitable device available
The `devlink -j port show` command output may not contain the "flavour"
key, an example from Ubuntu 22.10 s390x LPAR(5.19.0-37-generic), with
mlx4 driver and iproute2-5.15.0:
  {"port":{"pci/0001:00:00.0/1":{"type":"eth","netdev":"ens301"},
           "pci/0001:00:00.0/2":{"type":"eth","netdev":"ens301d1"},
           "pci/0002:00:00.0/1":{"type":"eth","netdev":"ens317"},
           "pci/0002:00:00.0/2":{"type":"eth","netdev":"ens317d1"}}}

This will cause a KeyError exception.

Create a validate_devlink_output() to check for this "flavour" from
devlink command output to avoid this KeyError exception. Also let
it handle the check for `devlink -j dev show` output in main().

Apart from this, if the test was not started because the max lanes of
the designated device is 0. The script will still return 0 and thus
causing a false-negative test result.

Use a found_max_lanes flag to determine if these tests were skipped
due to this reason and return KSFT_SKIP to make it more clear.

It tries to read data to NULL buffer (data already presents in socket's

data, because skbuff is not dropped, but for SOCK_SEQPACKET skbuff will
be dropped by kernel, and 'recv()' will return EAGAIN.

Todd Brandt 6fa7f53735 pm-graph: sleepgraph: Avoid crashing on binary data in device names
A regression has occurred in the hid-sensor code where a device
name string has not been initialized to 0, and ends up without
a NULL char and is printed with %s. This includes random binary
data in the device name, which makes its way into the ftrace output
and ends up crashing sleepgraph because it expects the ftrace output
to be ASCII only.

For example: "HID-SENSOR-INT-020b?.39.auto" ends up in ftrace instead
of "HID-SENSOR-INT-020b.39.auto". It causes this crash in sleepgraph:

  File "/usr/bin/sleepgraph", line 5579, in executeSuspend
    for line in fp:
  File "/usr/lib/python3.10/codecs.py", line 322, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position
1568: invalid start byte

The issue is present in 6.3-rc1 and is described in full here:
https://bugzilla.kernel.org/show_bug.cgi?id=217169

A separate fix has been submitted to have this issue repaired, but
it has also exposed a larger bug in sleepgraph, since nothing should
make sleepgraph crash. Sleepgraph needs to be able to handle binary
data showing up in ftrace gracefully.

Modify the ftrace processing code to treat it as potentially binary
and to filter out binary data and leave just the ASCII.

David Woodhouse e6239a4ec5 KVM: selftests: Add EVTCHNOP_send slow path test to xen_shinfo_test
When kvm_xen_evtchn_send() takes the slow path because the shinfo GPC
needs to be revalidated, it used to violate the SRCU vs. kvm->lock
locking rules and potentially cause a deadlock.

Now that lockdep is learning to catch such things, make sure that code
path is exercised by the selftest.

David Woodhouse e7062a98d0 KVM: selftests: Use enum for test numbers in xen_shinfo_test
The xen_shinfo_test started off with very few iterations, and the numbers
we used in GUEST_SYNC() were precisely mapped to the RUNSTATE_xxx values
anyway to start with.

It has since grown quite a few more tests, and it's kind of awful to be
handling them all as bare numbers. Especially when I want to add a new
test in the middle. Define an enum for the test stages, and use it both
in the guest code and the host switch statement.

No functional change, if I can count to 24.

Paolo Bonzini 3dc40cf89b selftests: KVM: skip hugetlb tests if huge pages are not available
Right now, if KVM memory stress tests are run with hugetlb sources but hugetlb is
not available (either in the kernel or because /proc/sys/vm/nr_hugepages is 0)
the test will fail with a memory allocation error.

This makes it impossible to add tests that default to hugetlb-backed memory,
because on a machine with a default configuration they will fail.  Therefore,
check HugePages_Total as well and, if zero, direct the user to enable hugepages
in procfs.  Furthermore, return KSFT_SKIP whenever hugetlb is not available.

Pull clone3 fix from Christian Brauner:
 "A simple fix for the clone3() system call.

  The CLONE_NEWTIME allows the creation of time namespaces. The flag
  reuses a bit from the CSIGNAL bits that are used in the legacy clone()
  system call to set the signal that gets sent to the parent after the
  child exits.

  The clone3() system call doesn't rely on CSIGNAL anymore as it uses a
  dedicated .exit_signal field in struct clone_args. So we blocked all
  CSIGNAL bits in clone3_args_valid(). When CLONE_NEWTIME was introduced
  and reused a CSIGNAL bit we forgot to adapt clone3_args_valid()
  causing CLONE_NEWTIME with clone3() to be rejected. Fix this"
