SUNRPC: Fix a NULL pointer deref in trace_svc_stats_latency()

2021-09-15T08:02:24Z

[ Upstream commit 5c11720767f70d34357d00a15ba5a0ad052c40fe ] Some paths through svc_process() leave rqst->rq_procinfo set to NULL, which triggers a crash if tracing happens to be enabled. Fixes: 89ff87494c6e ("SUNRPC: Display RPC procedure names instead of proc numbers") Signed-off-by: Chuck Lever Signed-off-by: Sasha Levin

Pull NFS client updates from Trond Myklebust: "Highlights include: Features: - Multiple patches to add support for fcntl() leases over NFSv4. - A sysfs interface to display more information about the various transport connections used by the RPC client - A sysfs interface to allow a suitably privileged user to offline a transport that may no longer point to a valid server - A sysfs interface to allow a suitably privileged user to change the server IP address used by the RPC client Stable fixes: - Two sunrpc fixes for deadlocks involving privileged rpc_wait_queues Bugfixes: - SUNRPC: Avoid a KASAN slab-out-of-bounds bug in xdr_set_page_base() - SUNRPC: prevent port reuse on transports which don't request it. - NFSv3: Fix memory leak in posix_acl_create() - NFS: Various fixes to attribute revalidation timeouts - NFSv4: Fix handling of non-atomic change attribute updates - NFSv4: If a server is down, don't cause mounts to other servers to hang as well - pNFS: Fix an Oops in pnfs_mark_request_commit() when doing O_DIRECT - NFS: Fix mount failures due to incorrect setting of the has_sec_mnt_opts filesystem flag - NFS: Ensure nfs_readpage returns promptly when an internal error occurs - NFS: Fix fscache read from NFS after cache error - pNFS: Various bugfixes around the LAYOUTGET operation" * tag 'nfs-for-5.14-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (46 commits) NFSv4/pNFS: Return an error if _nfs4_pnfs_v3_ds_connect can't load NFSv3 NFSv4/pNFS: Don't call _nfs4_pnfs_v3_ds_connect multiple times NFSv4/pnfs: Clean up layout get on open NFSv4/pnfs: Fix layoutget behaviour after invalidation NFSv4/pnfs: Fix the layout barrier update NFS: Fix fscache read from NFS after cache error NFS: Ensure nfs_readpage returns promptly when internal error occurs sunrpc: remove an offlined xprt using sysfs sunrpc: provide showing transport's state info in the sysfs directory sunrpc: display xprt's queuelen of assigned tasks via sysfs sunrpc: provide multipath info in the sysfs directory NFSv4.1 identify and mark RPC tasks that can move between transports sunrpc: provide transport info in the sysfs directory SUNRPC: take a xprt offline using sysfs sunrpc: add dst_attr attributes to the sysfs xprt directory SUNRPC for TCP display xprt's source port in sysfs xprt_info SUNRPC query transport's source port SUNRPC display xprt's main value in sysfs's xprt_info SUNRPC mark the first transport sunrpc: add add sysfs directory per xprt under each xprt_switch ...

sunrpc: remove an offlined xprt using sysfs

2021-07-08T18:03:24Z

Once a transport has been put offline, this transport can be also removed from the list of transports. Any tasks that have been stuck on this transport would find the next available active transport and be re-tried. This transport would be removed from the xprt_switch list and freed.

NFSv4.1 identify and mark RPC tasks that can move between transports

2021-07-08T18:03:24Z

In preparation for when we can re-try a task on a different transport, identify and mark such RPC tasks as moveable. Only 4.1+ operarations can be re-tried on a different transport. Signed-off-by: Olga Kornievskaia Signed-off-by: Trond Myklebust

SUNRPC: take a xprt offline using sysfs

2021-07-08T18:03:24Z

Using sysfs's xprt_state attribute, mark a particular transport offline. It will not be picked during the round-robin selection. It's not allowed to take the main (1st created transport associated with the rpc_client) offline. Also bring a transport back online via sysfs by writing "online" and that would allow for this transport to be picked during the round- robin selection.

When an RPC client gets created it's first transport is special and should be marked a main transport. Signed-off-by: Olga Kornievskaia Signed-off-by: Trond Myklebust

sunrpc: add dst_attr attributes to the sysfs xprt directory

2021-07-08T18:03:24Z

Allow to query and set the destination's address of a transport. Setting of the destination address is allowed only for TCP or RDMA based connections. Signed-off-by: Olga Kornievskaia Signed-off-by: Trond Myklebust

sunrpc: add add sysfs directory per xprt under each xprt_switch

2021-07-08T18:03:23Z

Add individual transport directories under each transport switch group. For instance, for each nconnect=X connections there will be a transport directory. Naming conventions also identifies transport type -- xprt-- where type is udp, tcp, rdma, local, bc. Signed-off-by: Olga Kornievskaia Signed-off-by: Trond Myklebust
