selftests: mirror_gre_changes: Tighten up the TTL test match
This test verifies whether the encapsulated packets have the correct
configured TTL. It does so by sending ICMP packets through the test
topology and mirroring them to a gretap netdevice. On a busy host
however, more than just the test ICMP packets may end up flowing
through the topology, get mirrored, and counted. This leads to
potential spurious failures as the test observes much more mirrored
packets than the sent test packets, and assumes a bug.
Fix this by tightening up the mirror action match. Change it from
matchall to a flower classifier matching on ICMP packets specifically.

Including fixes from netfilter, wireless and bpf.
Still trending up in size but the good news is that the "current"
regressions are resolved, AFAIK.
We're getting weirdly many fixes for Wake-on-LAN and suspend/resume
handling on embedded this week (most not merged yet), not sure why.
But those are all for older bugs.
Current release - regressions:
- tls: set MSG_SPLICE_PAGES consistently when handing encrypted
data over to TCP
Current release - new code bugs:
- eth: mlx5: correct IDs on VFs internal to the device (IPU)
Previous releases - regressions:
- phy: at803x: fix WoL support / reporting on AR8032
- bonding: fix incorrect deletion of ETH_P_8021AD protocol VID
from slaves, leading to BUG_ON()
- tun: prevent tun_build_skb() from exceeding the packet size limit
- wifi: rtw89: fix 8852AE disconnection caused by RX full flags
- eth/PCI: enetc: fix probing after

perf tools fixes for v6.5: 3rd batch
- Revert a patch that unconditionally resolved addresses to inlines in
callchains, something that was done before when DWARF mode was asked
for, but could as well be done when just frame pointers (the default)
was selected. This enriches the callchains with inlines but the way to
resolve it is gross right now, relying on addr2line, and even if we come
up with an efficient way of processing all the associated DWARF info for
a big file as vmlinux is, this has to be something people opt-in, as it
will still result in overheads, so revert it until we get this done in a
saner way.
- Update the x86 msr-index.h header with the kernel original, no change
in tooling output, just addresses a tools/perf build warning.
- Resolve a regression where special "tool events", such as
"duration_time" were being presented for all CPUs, when it only makes
sense to show it for the workload, that is, just once.

selftests/bpf: Add sockmap test for redirecting partial skb data
Add a test case to check whether sockmap redirection works correctly when data length returned by stream_parser is less than skb->len. In addition, this test checks whether strp_done is called correctly. The reason is that we returns skb->len - 1 from the stream_parser, so the last byte in the skb will be held by strp->skb_head. Therefore, if strp_done is not called to free strp->skb_head, we'll get a memleak warning.

./test_progs:vsock_unix_redir_connectible:1525: ingress: want pass count 1, have 0
It’s because the recv(... MSG_DONTWAIT) syscall in the test case is
called before the queued work sk_psock_backlog() in the kernel finishes
executing. So the data to be read is still queued in psock->ingress_skb
and cannot be read by the user program. Therefore, the non-blocking
recv() reads nothing and reports an EAGAIN error.
So replace recv(... MSG_DONTWAIT) with xrecv_nonblock(), which calls
select() to wait for data to be readable or timeout before calls recv().

selftests: forwarding: tc_tunnel_key: Make filters more specific
The test installs filters that match on various IP fragments (e.g., no
fragment, first fragment) and expects a certain amount of packets to hit
each filter. This is problematic as the filters are not specific enough
and can match IP packets (e.g., IGMP) generated by the stack, resulting
in failures [1].
Fix by making the filters more specific and match on more fields in the
IP header: Source IP, destination IP and protocol.

were not hit zero times. Using tc_check_at_least_x_packets() is also an
option, but it is not available in older kernels.

selftests: forwarding: Switch off timeout
The default timeout for selftests is 45 seconds, but it is not enough for forwarding selftests which can takes minutes to finish depending on the number of tests cases: # make -C tools/testing/selftests TARGETS=net/forwarding run_tests TAP version 13 1..102 # timeout set to 45 # selftests: net/forwarding: bridge_igmp.sh # TEST: IGMPv2 report 239.10.10.10 [ OK ] # TEST: IGMPv2 leave 239.10.10.10 [ OK ] # TEST: IGMPv3 report 239.10.10.10 is_include [ OK ] # TEST: IGMPv3 report 239.10.10.10 include -> allow [ OK ] # not ok 1 selftests: net/forwarding: bridge_igmp.sh # TIMEOUT 45 seconds Fix by switching off the timeout and setting it to 0.

selftests: forwarding: Skip test when no interfaces are specified
As explained in [1], the forwarding selftests are meant to be run with
either physical loopbacks or veth pairs. The interfaces are expected to
be specified in a user-provided forwarding.config file or as command
line arguments. By default, this file is not present and the tests fail:
# make -C tools/testing/selftests TARGETS=net/forwarding run_tests
[...]
TAP version 13

# Command line is not complete. Try option "help"
# Failed to create netif
not ok 1 selftests: net/forwarding: bridge_igmp.sh # exit=1
[...]
Fix by skipping a test if interfaces are not provided either via the
configuration file or command line arguments.
# make -C tools/testing/selftests TARGETS=net/forwarding run_tests

nexthop: Fix infinite nexthop bucket dump when using maximum nexthop ID
A netlink dump callback can return a positive number to signal that more
information needs to be dumped or zero to signal that the dump is
complete. In the second case, the core netlink code will append the
NLMSG_DONE message to the skb in order to indicate to user space that
the dump is complete.
The nexthop bucket dump callback always returns a positive number if
nexthop buckets were filled in the provided skb, even if the dump is
complete. This means that a dump will span at least two recvmsg() calls
as long as nexthop buckets are present. In the last recvmsg() call the
dump callback will not fill in any nexthop buckets because the previous
call indicated that the dump should restart from the last dumped nexthop
ID plus one.
# ip link add name dummy1 up type dummy
# ip nexthop add id 1 dev dummy1

This behavior is both inefficient and buggy. If the last nexthop to be
dumped had the maximum ID of 0xffffffff, then the dump will restart from
0 (0xffffffff + 1) and never end:

This happens because of two reasons:
- iproute v6.3.0 does not support the implicit flag, fixed with
iproute2-next commit 3a2535a41854 ("mptcp: add support for implicit
flag")
- pm_nl_check_endpoint wrongly expects the ip address to be repeated two
times in iproute output, and does not account for a final whitespace
in it.
This fixes the issue trimming the whitespace in the output string and
removing the double address in the expected string.

This happens because endpoint delete includes an ip address while id is

"When used with the delete id operation, an IFADDR is only included when
the ID is 0."
This fixes the issue using the $addr variable in pm_nl_del_endpoint()
only when id is 0.

selftests: net: test vxlan pmtu exceptions with tcp
TCP might get stuck if a nonlinear skb exceeds the path MTU, icmp error contains an incorrect icmp checksum in that case. Extend the existing test for vxlan to also send at least 1MB worth of data via TCP in addition to the existing 'large icmp packet adds route exception'. On my test VM this fails due to 0-size output file without "tunnels: fix kasan splat when generating ipv4 pmtu error".

selftests: cgroup: fix test_kmem_basic false positives
This test fails routinely in our prod testing environment, and I can reproduce it locally as well. The test allocates dcache inside a cgroup, then drops the memory limit and checks that usage drops correspondingly. The reason it fails is because dentries are freed with an RCU delay - a debugging sleep shows that usage drops as expected shortly after. Insert a 1s sleep after dropping the limit. This should be good enough, assuming that machines running those tests are otherwise not very busy.

selftests: mm: ksm: fix incorrect evaluation of parameter
A missing break in kms_tests leads to kselftest hang when the parameter -s
is used.
In current code flow because of missing break in -s, -t parses args
spilled from -s and as -t accepts only valid values as 0,1 so any arg in
-s >1 or <0, gets in ksm_test failure
This went undetected since, before the addition of option -t, the next
case -M would immediately break out of the switch statement but that is no
longer the case
Add the missing break statement.

radix tree test suite: fix incorrect allocation size for pthreads
Currently the pthread allocation for each array item is based on the size
of a pthread_t pointer and should be the size of the pthread_t structure,
so the allocation is under-allocating the correct size. Fix this by using
the size of each element in the pthreads array.
Static analysis cppcheck reported:
tools/testing/radix-tree/regression1.c:180:2: warning: Size of pointer
'threads' used instead of size of its data. [pointerSize]
