[PATCH mptcp-net] mptcp: consolidate suboption status.
Posted by Paolo Abeni 5 days, 17 hours ago 
MPTCP maintains the received sub-options status is the bitmask carrying
the received suboptions and in several bitfields carrying per suboption
additional info.

Zeroing the bitmask before parsing is not enough to ensure a consistent
status, and the MPTCP code has to additionally clear some bitfiled
depending on the actually parsed suboption.

The above schema is fragile, and syzbot menaged to trigger a path where
a relevant bitfield is not cleared/initialized:

The current schema is too fragile; address the issue grouping all the
state-related data together and clearing the whole group instead of
just the bitmask. This also cleans-up the code a bit, as there is no
need anymore to individually clear "random" bitfield in a couple of
places.
