[PATCH net 0/2] mptcp: blackhole only if 1st SYN retrans w/o MPC is accepted

[Matthieu Baerts (NGI0)]

Here are two small fixes for issues introduced in v6.12.

- Patch 1: reset the mpc_drop mark for other SYN retransmits, to only
  consider an MPTCP blackhole when the first SYN retransmitted without
  the MPTCP options is accepted, as initially intended.

- Patch 2: also mention in the doc that the blackhole_timeout sysctl
  knob is per-netns, like all the others.

Notes:
- The Cc stable tag has only been added to the first patch, I don't
  think it is usually added on fixes related to the doc, right?
- A Fixes tag is present in both patches: I hope that's also OK for the
  one modifying the doc. It can be removed if preferred.
