This is a problem due to rxrpc being switched to acting as a UDP tunnel, thereby allowing it to steal the packets before they go through the UDP Rx queue. UDP tunnels can't get ICMP/ICMP6 packets, however. This patch adds an additional encap hook so that they can. (2) Fix the encryption routines in rxkad to handle packets that have more than three parts correctly. The problem is that ->nr_frags doesn't count the initial fragment, so the sglist ends up too short. (3) Fix a problem with destruction of the local endpoint potentially getting repeated. (4) Fix the calculation of the time at which to resend. jiffies_to_usecs() gives microseconds, not nanoseconds. (5) Fix AFS to work out when callback promises and locks expire based on the time an op was issued rather than the time the first reply packet arrives. We don't know how long the server took between calculating the expiry interval and transmitting the reply. (6) Given (5), rxrpc_get_reply_time() is no longer used, so remove it. The patches are tagged here: git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git rxrpc-fixes-20220831 and can also be found on the following branch: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=rxrpc-fixes Changes ======= ver #2) - Added some missing cpp-conditionals for rxrpc IPV6 support. - Replaced the callback promise time calculation patch with one that used the time of op issue rather than time of first reply packet as a base. - Added an additional patch to remove the rxrpc function to retrieve the time of first reply.
