-0800 Merge tag 'rxrpc-iothread-20240305' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== Here are some changes to AF_RXRPC: (1) Cache the transmission serial number of ACK and DATA packets in the rxrpc_txbuf struct and log this in the retransmit tracepoint. (2) Don't use atomics on rxrpc_txbuf::flags[*] and cache the intended wire header flags there too to avoid duplication. (3) Cache the wire checksum in rxrpc_txbuf to make it easier to create jumbo packets in future (which will require altering the wire header to a jumbo header and restoring it back again for retransmission). (4) Fix the protocol names in the wire ACK trailer struct. (5) Strip all the barriers and atomics out of the call timer tracking[*]. (6) Remove atomic handling from call->tx_transmitted and call->acks_prev_seq[*]. (7) Don't bother resetting the DF flag after UDP packet transmission. To change it, we now call directly into UDP code, so it's quick just to set it every time. (8) Merge together the DF/non-DF branches of the DATA transmission to reduce duplication in the code. (9) Add a kvec array into rxrpc_txbuf and start moving things over to it. This paves the way for using page frags. (10) Split (sub)packet preparation and timestamping out of the DATA transmission function. This helps pave the way for future jumbo packet generation. (11) In rxkad, don't pick values out of the wire header stored in rxrpc_txbuf, buf rather find them elsewhere so we can remove the wire header from there. (12) Move rxrpc_send_ACK() to output.c so that it can be merged with rxrpc_send_ack_packet(). (13) Use rxrpc_txbuf::kvec[0] to access the wire header for the packet rather than directly accessing the copy in rxrpc_txbuf. This will allow that to be removed to a page frag. (14) Switch from keeping the transmission buffers in rxrpc_txbuf allocated in the slab to allocating them using page fragment allocators. There are separate allocators for DATA packets (which persist for a while) and control packets (which are discarded immediately). We can then turn on MSG_SPLICE_PAGES when transmitting DATA and ACK packets. We can also get rid of the RCU cleanup on rxrpc_txbufs, preferring instead to release the page frags as soon as possible. (15) Parse received packets before handling timeouts as the former may reset the latter. (16) Make sure we don't retransmit DATA packets after all the packets have been ACK'd. (17) Differentiate traces for PING ACK transmission. (18) Switch to keeping timeouts as ktime_t rather than a number of jiffies as the latter is too coarse a granularity. Only set the call timer at the end of the call event function from the aggregate of all the timeouts, thereby reducing the number of timer calls made. In future, it might be possible to reduce the number of timers from one per call to one per I/O thread and to use a high-precision timer. (19) Record RTT probes after successful transmission rather than recording it before and then cancelling it after if unsuccessful[*]. This allows a number of calls to get the current time to be removed. (20) Clean up the resend algorithm as there's now no need to walk the transmission buffer under lock[*]. DATA packets can be retransmitted as soon as they're found rather than being queued up and transmitted when the locked is dropped. (21) When initially parsing a received ACK packet, extract some of the fields from the ack info to the skbuff private data. This makes it easier to do path MTU discovery in the future when the call to which a PING RESPONSE ACK refers has been deallocated. [*] Possible with the move of almost all code from softirq context to the I/O thread.
