2018-08-21pNFS: Remove unwanted optimisation of layoutgetTrond Myklebust1-6/+0
If we knew that the file was empty, we wouldn't be asking for a layout. Any optimisation here is already done before calling pnfs_update_layout(). As it stands, we sometimes end up doing an unnecessary inband read to the MDS even when holding a layout.

2018-08-08NFS: Use an appropriate work queue for direct-write completionNeilBrown1-1/+1
When a direct-write completes, a work_struct is schedule to handle the completion. When NFS is being used for swap, the direct write might be a swap-out, so memory allocation can block until the write completes. The work queue currently used is not WQ_MEM_RECLAIM, so tasks can block waiting for memory - this leads to deadlock. So use nfsiod_workqueue instead. This will always have a running thread, and work items should never block waiting for memory. Signed-off-by: Neil Brown <neilb@suse.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>

2018-07-31NFSv4 client live hangs after live data migration recoveryBill Baker1-1/+8
After a live data migration event at the NFS server, the client may send I/O requests to the wrong server, causing a live hang due to repeated recovery events. On the wire, this will appear as an I/O request failing with NFS4ERR_BADSESSION, followed by successful CREATE_SESSION, repeatedly. NFS4ERR_BADSSESSION is returned because the session ID being used was issued by the other server and is not valid at the old server. The failure is caused by async worker threads having cached the transport (xprt) in the rpc_task structure. After the migration recovery completes, the task is redispatched and the task resends the request to the wrong server based on the old value still present in tk_xprt. The solution is to recompute the tk_xprt field of the rpc_task structure so that the request goes to the correct server.

2018-07-31sunrpc: Change rpc_print_iostats to rpc_clnt_show_stats and handle rpc_clnt clonesDave Wysochanski1-1/+1
The existing rpc_print_iostats has a few shortcomings. First, the naming is not consistent with other functions in the kernel that display stats. Second, it is really displaying stats for an rpc_clnt structure as it displays both xprt stats and per-op stats. Third, it does not handle rpc_clnt clones, which is important for the one in-kernel tree caller of this function, the NFS client's nfs_show_stats function. Fix all of the above by renaming the rpc_print_iostats to rpc_clnt_show_stats and looping through any rpc_clnt clones via cl_parent. Once this interface is fixed, this addresses a problem with NFSv4. Before this patch, the /proc/self/mountstats always showed incorrect counts for NFSv4 lease and session related opcodes such as SEQUENCE, RENEW, SETCLIENTID, CREATE_SESSION, etc. These counts were always 0 even though many ops would go over the wire. The reason for this is there are multiple rpc_clnt structures allocated for any given NFSv4 mount, and inside nfs_show_stats() we callled into rpc_print_iostats() which only handled one of them, nfs_server->client. Fix these counts by calling sunrpc's new rpc_clnt_show_stats() function, which handles cloned rpc_clnt structs and prints the stats together. Note that one side-effect of the above is that multiple mounts from the same NFS server will show identical counts in the above ops due to the fact the one rpc_clnt (representing the NFSv4 client state) is shared across mounts.

RFC5661 doesn't state directly that the client should update the layout stateid if it returns NFS4ERR_NOMATCHING_LAYOUT in response to a recall, however it does state that this error will "cleanly indicate completion" on par with returning the layout. For this reason, we assume that the client should update the layout stateid. The Linux pNFS server definitely does expect this behaviour. However, if the client replies NFS4ERR_DELAY, then it is stating that the recall was not processed, so it would be very wrong to update the layout stateid.

If we meet a conflicting object that is marked FSCACHE_OBJECT_IS_LIVE in the active object tree, we have been emitting a BUG after logging information about it and the new object. Instead, we should wait for the CACHEFILES_OBJECT_ACTIVE flag to be cleared on the old object (or return an error). The ACTIVE flag should be cleared after it has been removed from the active object tree. A timeout of 60s is used in the wait, so we shouldn't be able to get stuck there.
