Subject[PATCH net-next 0/7] rxrpc: Miscellaneous changes
From
Date

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:

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git
rxrpc-next-20220520

and can also be found on the following branch:
