[PATCH mptcp-next 0/4] Fixes for "mptcp: pm: drop TCP TS with ADD_ADDRv6 + port"

[Matthieu Baerts (NGI0)]

This address Eric's comments from [1].

Note that the CI will complain that not each patch can be built
individually. That's normal: the fix from patch 2 has to be split in
patch 3, to be applied in the right commit.

Use READ_ONCE() over sysctls. This will avoid future patches from KCSAN

[PATCH mptcp-next 2/4] Squash to "tcp: allow mptcp to drop TS for some packets"

[Matthieu Baerts (NGI0)]

Not to pass another local variables' addresses which forces the compiler
to use a stack canary in this hot function, even for non-MPTCP flows.

See Eric's comment.

Notes:

 - Using a free unused bit in struct mptcp_out_options. A bit "hackish",
   but I didn't see another way to avoid passing a local variable
   address.

 - Still adding a new parameter to mptcp_established_options, clearer.

 - IS_ENABLED(CONFIG_MPTCP) is needed to avoid compilation errors when
   reading/setting opts->mptcp.drop_ts.

[PATCH mptcp-next 4/4] mptcp: use READ_ONCE() over sysctls

[Matthieu Baerts (NGI0)]

To avoid KCSAN issues.

This patch is in theory for -net, and will need to be split in multiple
patches, with different Fixes tags. But I prefer to wait for Eric's
patches, as I noticed he already started to modify mptcp_is_enabled:

  https://lore.kernel.org/CANn89iLdwhhwLyO6zRjWMEY3t9g60ZE8ZhOVx33ucg_uRETbmQ@mail.gmail.com

Still, keeping this patch in this series, not to forget about it.

I hesitated for a moment about why READ_ONCE() was not added in
mptcp_get_path_manager() and mptcp_get_scheduler(), and the result is
that they are defined as arrays rather than pointers, so READ_ONCE() is
not applicable.

So this patch looks good to me.

If there are some issues, you can reproduce them using the same environment as

Please note that despite all the efforts that have been already done to have a
stable tests suite when executed on a public CI like here, it is possible some
reported issues are not due to your modifications. Still, do not hesitate to
help us improve that ;-)

I'm going to apply patches 1-3, because they have been requested by
Eric, I guess that's fine. After that, I will apply Eric's patch [1]
with the small fix in our tree, resolve conflicts, and send an extra fix.
