c2b5aa7aeb KVM: arm64: selftests: Remove print_reg's dependency on vcpu_config
print_reg() and its helpers only use the vcpu_config pointer for
config_name(). So just pass the config name in instead, which is used
as a prefix in asserts. print_reg() can now be compiled independently
of config_name().

2653860812 KVM: arm64: selftests: Drop SVE cap check in print_reg
The check doesn't prove much anyway, as the reg lists could be
messed up too. Just drop the check to simplify making print_reg
more independent.

dfaf20af76 KVM: arm64: selftests: Replace str_with_index with strdup_printf
The original author of aarch64/get-reg-list.c (me) was wearing
tunnel vision goggles when implementing str_with_index(). There's
no reason to have such a special case string function. Instead,
take inspiration from glib and implement strdup_printf. The
implementation builds on vasprintf() which requires _GNU_SOURCE,
but we require _GNU_SOURCE in most files already.

c8c101ae39 selftests: mptcp: join: fix 'implicit EP' test
mptcp_join 'implicit EP' test currently fails when using ip mptcp:

  $ ./mptcp_join.sh -iI
  <snip>
  001 implicit EP    creation[fail] expected '10.0.2.2 10.0.2.2 id 1 implicit' found '10.0.2.2 id 1 rawflags 10 '

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.

aaf2123a5c selftests: mptcp: join: fix 'delete and re-add' test
mptcp_join 'delete and re-add' test fails when using ip mptcp:

                                           after delete[fail] got 2:2 subflows expected 1

This happens because endpoint delete includes an ip address while id is
not 0, contrary to what is indicated in the ip mptcp man page:

"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.

fac2650276 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.

65294de30c 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.

d6da04b6fb kselftest/arm64: Exit streaming mode after collecting signal context
When we collect a signal context with one of the SME modes enabled we will
have enabled that mode behind the compiler and libc's back so they may
issue some instructions not valid in streaming mode, causing spurious
failures.

For the code prior to issuing the BRK to trigger signal handling we need to
stay in streaming mode if we were already there since that's a part of the
signal context the caller is trying to collect. Unfortunately this code
includes a memset() which is likely to be heavily optimised and is likely
to use FP instructions incompatible with streaming mode. We can avoid this
happening by open coding the memset(), inserting a volatile assembly
statement to avoid the compiler recognising what's being done and doing
something in optimisation. This code is not performance critical so the
inefficiency should not be an issue.

After collecting the context we can simply exit streaming mode, avoiding
these issues. Use a full SMSTOP for safety to prevent any issues appearing
with ZA.

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bpf and wireless.

  Nothing scary here. Feels like the first wave of regressions from v6.5
  is addressed - one outstanding fix still to come in TLS for the
  sendpage rework.

  Current release - regressions:

   - udp: fix __ip_append_data()'s handling of MSG_SPLICE_PAGES

   - dsa: fix older DSA drivers using phylink

  Previous releases - regressions:

   - gro: fix misuse of CB in udp socket lookup

   - mlx5: unregister devlink params in case interface is down

   - Revert "wifi: ath11k: Enable threaded NAPI"

  Previous releases - always broken:

   - sched: cls_u32: fix match key mis-addressing

   - sched: bind logic fixes for cls_fw, cls_u32 and cls_route

   - add bound checks to a number of places which hand-parse netlink

   - bpf: disable preemption in perf_event_output helpers code

   - qed: fix scheduling in a tasklet while getting stats

   - avoid using APIs which are not hardirq-safe in couple of drivers,
     when we may be in a hard IRQ (netconsole)

   - wifi: cfg80211: fix return value in scan logic, avoid page
     allocator warning

   - wifi: mt76: mt7615: do not advertise 5 GHz on first PHY of MT7615D
     (DBDC)

  Misc:

   - drop handful of inactive maintainers, put some new in place"

9f1179fbbd selftests: openvswitch: support key masks
The default value for the mask actually depends on the value (e.g: if
the value is non-null, the default is full-mask), so change the convert
functions to accept the full, possibly masked string and let them figure
out how to parse the different values.

Also, implement size-aware int parsing.

With this patch we can now express flows such as the following:
"eth(src=0a:ca:fe:ca:fe:0a/ff:ff:00:00:ff:00)"
"eth(src=0a:ca:fe:ca:fe:0a)" -> mask = ff:ff:ff:ff:ff:ff
"ipv4(src=192.168.1.1)" -> mask = 255.255.255.255
"ipv4(src=192.168.1.1/24)"
"ipv4(src=192.168.1.1/255.255.255.0)"
"tcp(src=8080)" -> mask = 0xffff
"tcp(src=8080/0xf0f0)"

918423fda9 selftests: openvswitch: add an initial flow programming case
The openvswitch self-tests can test much of the control side of
the module (ie: what a vswitchd implementation would process),
but the actual packet forwarding cases aren't supported, making
the testing of limited value.

Add some flow parsing and an initial ARP based test case using
arping utility.  This lets us display flows, add some basic
output flows with simple matches, and test against a known good
forwarding case.
