Here are some miscellaneous changes for AF_RXRPC:
(1) Allow the list of local endpoints to be viewed through /proc.
(2) Switch to using refcount_t for refcounting.
(3) Fix a locking issue found by lockdep.
(4) Autogenerate tracing symbol enums from symbol->string maps to make it
easier to keep them in sync.
(5) Return an error to sendmsg() if a call it tried to set up failed.
Because it failed at this point, no notification will be generated for
recvmsg to pick up - but userspace still needs to know about the
failure.
(6) Fix the selection of abort codes generated by internal events. In
particular, rxrpc and kafs shouldn't be generating RX_USER_ABORT
unless it's because userspace did something to cancel a call.
(7) Adjust the interpretation and handling of certain ACK types to try and
detect NAT changes causing a call to seem to start mid-flow from a
different peer.
The patches are tagged here:
