Justin Worrell 2f7f112eae SUNRPC: call xs_sock_process_cmsg for all cmsg ...

[ Upstream commit 9559d2fffd ]

xs_sock_recv_cmsg was failing to call xs_sock_process_cmsg for any cmsg
type other than TLS_RECORD_TYPE_ALERT (TLS_RECORD_TYPE_DATA, and other
values not handled.) Based on my reading of the previous commit
(cc5d5908: sunrpc: fix client side handling of tls alerts), it looks
like only iov_iter_revert should be conditional on TLS_RECORD_TYPE_ALERT
(but that other cmsg types should still call xs_sock_process_cmsg). On
my machine, I was unable to connect (over mtls) to an NFS share hosted
on FreeBSD. With this patch applied, I am able to mount the share again.
