[PATCH v2 mptcp-next 0/3] mptcp: add support for mixed v4/v6

Posted by Paolo Abeni 1 year, 3 months ago

The core MPTCP implementation is just a few bits of to support such
feature, we just need to allow specifying the subflow family explicitly
(patch 1/3) and remove the artificial constraint currently enforcing
no mixed subflow in place (patch 2/3)

Some self-tests added on patch 3/3

Merry Xmas ;)

v1 -> v2:
 - only allow mixing family for ipv6 mptcp socket with no IPV6_ONLY
   option (all the functional changes in 2/3 plus self-tests adaptation)

Paolo Abeni (3):
  mptcp: explicitly specify sock family at subflow creation time
  mptcp: let the in kernel PM use mixed ipv4 and ipv6 addresses
  selftests: mptcp: add test-cases for mixed v4/v6 subflows
