rxrpc: Fix service endpoint expiry 2017-11-24T10:18:42+00:00 David Howells dhowells@redhat.com 2017-11-24T10:18:42+00:00 f859ab61875978eeaa539740ff7f7d91f5d60006 RxRPC service endpoints expire like they're supposed to by the following means: (1) Mark dead rxrpc_net structs (with ->live) rather than twiddling the global service conn timeout, otherwise the first rxrpc_net struct to die will cause connections on all others to expire immediately from then on. (2) Mark local service endpoints for which the socket has been closed (->service_closed) so that the expiration timeout can be much shortened for service and client connections going through that endpoint. (3) rxrpc_put_service_conn() needs to schedule the reaper when the usage count reaches 1, not 0, as idle conns have a 1 count. (4) The accumulator for the earliest time we might want to schedule for should be initialised to jiffies + MAX_JIFFY_OFFSET, not ULONG_MAX as the comparison functions use signed arithmetic. (5) Simplify the expiration handling, adding the expiration value to the idle timestamp each time rather than keeping track of the time in the past before which the idle timestamp must go to be expired. This is much easier to read. (6) Ignore the timeouts if the net namespace is dead. (7) Restart the service reaper work item rather the client reaper.

rxrpc: Add a timeout for detecting lost ACKs/lost DATA 2017-11-24T10:18:42+00:00 David Howells dhowells@redhat.com 2017-11-24T10:18:42+00:00 bd1fdf8cfdf3fdbccd2b21c33ec649ebd7429af7 Add an extra timeout that is set/updated when we send a DATA packet that has the request-ack flag set. This allows us to detect if we don't get an ACK in response to the latest flagged packet. The ACK packet is adjudged to have been lost if it doesn't turn up within 2*RTT of the transmission. If the timeout occurs, we schedule the sending of a PING ACK to find out the state of the other side. If a new DATA packet is ready to go sooner, we cancel the sending of the ping and set the request-ack flag on that instead. If we get back a PING-RESPONSE ACK that indicates a lower tx_top than what we had at the time of the ping transmission, we adjudge all the DATA packets sent between the response tx_top and the ping-time tx_top to have been lost and retransmit immediately. Rather than sending a PING ACK, we could just pick a DATA packet and speculatively retransmit that with request-ack set. It should result in either a REQUESTED ACK or a DUPLICATE ACK which we can then use in lieu the a PING-RESPONSE ACK mentioned above. Signed-off-by: David Howells <dhowells@redhat.com>

By analogy with other rx implementations, there should be three timeouts: (1) "Normal timeout" This is set for all calls and is triggered if we haven't received any packets from the peer in a while. It is measured from the last time we received any packet on that call. This is not reset by any connection packets (such as CHALLENGE/RESPONSE packets). If a service operation takes a long time, the server should generate PING ACKs at a duration that's substantially less than the normal timeout so is to keep both sides alive. This is set at 1/6 of normal timeout. (2) "Idle timeout" This is set only for a service call and is triggered if we stop receiving the DATA packets that comprise the request data. It is measured from the last time we received a DATA packet. (3) "Hard timeout" This can be set for a call and specified the maximum lifetime of that call. It should not be specified by default. Some operations (such as volume transfer) take a long time. Allow userspace to set/change the timeouts on a call with sendmsg, using a control message: RXRPC_SET_CALL_TIMEOUTS The data to the message is a number of 32-bit words, not all of which need be given: u32 hard_timeout; /* sec from first packet */ u32 idle_timeout; /* msec from packet Rx */ u32 normal_timeout; /* msec from data Rx */ This can be set in combination with any other sendmsg() that affects a call.

Pull NFS client updates from Anna Schumaker:
 "Stable bugfixes:
   - Revalidate "." and ".." correctly on open
   - Avoid RCU usage in tracepoints
   - Fix ugly referral attributes
   - Fix a typo in nomigration mount option
   - Revert "NFS: Move the flock open mode check into nfs_flock()"

  Features:
   - Implement a stronger send queue accounting system for NFS over RDMA
   - Switch some atomics to the new refcount_t type

  Other bugfixes and cleanups:
   - Clean up access mode bits
   - Remove special-case revalidations in nfs_opendir()
   - Improve invalidating NFS over RDMA memory for async operations that
     time out
   - Handle NFS over RDMA replies with a worqueue
   - Handle NFS over RDMA sends with a workqueue
   - Fix up replaying interrupted requests
   - Remove dead NFS over RDMA definitions
   - Update NFS over RDMA copyright information
   - Be more consistent with bool initialization and comparisons
   - Mark expected switch fall throughs
   - Various sunrpc tracepoint cleanups
   - Fix various OPEN races
   - Fix a typo in nfs_rename()
   - Use common error handling code in nfs_lock_and_join_request()
   - Check that some structures are properly cleaned up during
     net_exit()
   - Remove net pointer from dprintk()s"
