selftests/powerpc: Fix fpu_signal failures

2024-03-01T11:15:30+00:00

My recent commit e5d00aaac651 ("selftests/powerpc: Check all FPRs in
fpu_preempt") inadvertently broke the fpu_signal test.

It needs to take into account that fpu_preempt now loads 32 FPRs, so
enlarge darray.

Also use the newly added randomise_darray() to properly randomise darray.

Finally the checking done in signal_fpu_sig() needs to skip checking
f30/f31, because they are used as scratch registers in check_all_fprs(),
called by preempt_fpu(), and so could hold other values when the signal
is taken.

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

Patch #1 restores NFPROTO_INET with nft_compat, from Ignat Korchagin.

Patch #2 fixes an issue with bridge netfilter and broadcast/multicast
packets.

There is a day 0 bug in br_netfilter when used with connection tracking.

Conntrack assumes that an nf_conn structure that is not yet added to
hash table ("unconfirmed"), is only visible by the current cpu that is
processing the sk_buff.

For bridge this isn't true, sk_buff can get cloned in between, and
clones can be processed in parallel on different cpu.

This patch disables NAT and conntrack helpers for multicast packets.

Patch #3 adds a selftest to cover for the br_netfilter bug.

tools: ynl: fix handling of multiple mcast groups

2024-02-28T23:24:34+00:00

We never increment the group number iterator, so all groups
get recorded into index 0 of the mcast_groups[] array.

As a result YNL can only handle using the last group.
For example using the "netdev" sample on kernel with
page pool commands results in:

  $ ./samples/netdev
  YNL: Multicast group 'mgmt' not found

Most families have only one multicast group, so this hasn't
been noticed. Plus perhaps developers usually test the last
group which would have worked.

selftests: mptcp: explicitly trigger the listener diag code-path

2024-02-27T02:41:56+00:00

The mptcp diag interface already experienced a few locking bugs
that lockdep and appropriate coverage have detected in advance.

Let's add a test-case triggering the relevant code path, to prevent
similar issues in the future.

Be careful to cope with very slow environments.

Note that we don't need an explicit timeout on the mptcp_connect
subprocess to cope with eventual bug/hang-up as the final cleanup
terminating the child processes will take care of that.

Commands 'ss -M' are used in script mptcp_join.sh to display only MPTCP
sockets. So it must be checked if ss tool supports MPTCP in this script.

selftests: mptcp: rm subflow with v4/v4mapped addr

2024-02-27T02:41:55+00:00

Now both a v4 address and a v4-mapped address are supported when
destroying a userspace pm subflow, this patch adds a second subflow
to "userspace pm add & remove address" test, and two subflows could
be removed two different ways, one with the v4mapped and one with v4.
