Subject: [PATCH net 0/3] mptcp: Fixes for buffer reclaim and option writing

Here are three fixes dealing with a syzkaller crash MPTCP triggers in
the memory manager in 5.16-rc8, and some option writing problems.

Patches 1 and 2 fix some corner cases in MPTCP option writing.

Patch 3 addresses a crash that syzkaller found a way to trigger in the mm
subsystem by passing an invalid value to __sk_mem_reduce_allocated().


Geliang Tang (1):
  mptcp: fix a DSS option writing error

Mat Martineau (1):
  mptcp: Check reclaim amount before reducing allocation

Matthieu Baerts (1):
  mptcp: fix opt size when sending DSS + MP_FAIL
