Merge branch 'mptcp-userspace-pm-create-sockets-for-the-right-family'
Matthieu Baerts says:
====================
mptcp: userspace pm: create sockets for the right family
Before these patches, the Userspace Path Manager would allow the
creation of subflows with wrong families: taking the one of the MPTCP
socket instead of the provided ones and resulting in the creation of
subflows with likely not the right source and/or destination IPs. It
would also allow the creation of subflows between different families or
not respecting v4/v6-only socket attributes.
Patch 1 lets the userspace PM select the proper family to avoid creating
subflows with the wrong source and/or destination addresses because the
family is not the expected one.
Patch 2 makes sure the userspace PM doesn't allow the userspace to
create subflows for a family that is not allowed.
Patch 3 validates scenarios with a mix of v4 and v6 subflows for the
same MPTCP connection.
These patches fix issues introduced in v5.19 when the userspace path
manager has been introduced.
