MFS r352509:
Only allow a SCTP-AUTH shared key to be updated by the application
if it is not deactivated and not used.
This avoids a use-after-free problem.
MFS r352674:
Fix the handling of invalid parameters in ASCONF chunks.
Thanks to Mark Wodrich from Google for reproting the issue in
https://github.com/sctplab/usrsctp/issues/376
for the userland stack.
MFS r352675:
Cleanup the RTO calculation and perform some consistency checks
before computing the RTO.
This should fix an overflow issue reported by Felix Weinrank in
https://github.com/sctplab/usrsctp/issues/375
for the userland stack and found by running a fuzz tester.
MFS r352676:
Don't hold the info lock when calling sctp_select_a_tag().
This avoids a double lock bug in the NAT colliding state processing
of SCTP. Thanks to Felix Weinrank for finding and reporting this issue in
https://github.com/sctplab/usrsctp/issues/374
He found this bug using fuzz testing.
