2021-08-30NFS: Always provide aligned buffers to the RPC read layersTrond Myklebust
Instead of messing around with XDR padding in the RDMA layer, we should just give the RPC layer an aligned buffer. Try to avoid creating extra RPC calls by aligning to the smaller value of ALIGN(len, rsize) and PAGE_SIZE.

2021-08-27NFSv4.1 add network transport when session trunking is detectedOlga Kornievskaia
After trunking is discovered in nfs4_discover_server_trunking(), add the transport to the old client structure if the allowed limit of transports has not been reached. An example: there exists a multi-homed server and client mounts one server address and some volume and then doest another mount to a different address of the same server and perhaps a different volume. Previously, the client checks that this is a session trunkable servers (same server), and removes the newly created client structure along with its transport. Now, the client adds the connection from the 2nd mount into the xprt switch of the existing client (it leads to having 2 available connections).

2021-08-27SUNRPC enforce creation of no more than max_connect xprtsOlga Kornievskaia
If we are adding new transports via rpc_clnt_test_and_add_xprt() then check if we've reached the limit. Currently only pnfs path adds transports via that function but this is done in preparation when the client would add new transports when session trunking is detected. A warning is logged if the limit is reached. Signed-off-by: Olga Kornievskaia <kolga@netapp.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
2021-08-27NFSv4 introduce max_connect mount optionsOlga Kornievskaia
This option will control up to how many xprts can the client establish to the server with a distinct address (that means nconnect connections are not counted towards this new limit). This patch is setting up nfs structures to keeep track of the max_connect limit (does not enforce it). The default value is kept at 1 so that no current mounts that don't want any additional connections would be effected. The maximum value is set at 16. Mounts to DS are not limited to default value of 1 but instead set to the maximum default value of 16 (NFS_MAX_TRANSPORTS).

2021-08-27SUNRPC keep track of number of transports to unique addressesOlga Kornievskaia
Currently, xprt_switch keeps a number of all xprts (xps_nxprts) that were added to the switch regardless of whethere it's an nconnect transport or a transport to a trunkable address. Introduce a new counter to keep track of transports to unique destination addresses per xprt_switch.

2021-08-27SUNRPC: Tweak TCP socket shutdown in the RPC clientTrond Myklebust
We only really need to call shutdown() if we're in the ESTABLISHED TCP state, since that is the only case where the client is initiating a close of an established connection. If the socket is in FIN_WAIT1 or FIN_WAIT2, then we've already initiated socket shutdown and are waiting for the server's reply, so do nothing. In all other cases where we've already received a FIN from the server, we should be able to just close the socket.

2021-08-27SUNRPC: Simplify socket shutdown when not reusing TCP portsTrond Myklebust
If we're not required to reuse the TCP port, then we can just immediately close the socket, and leave the cleanup details to the TCP layer.

2021-08-10NFSv4.2: remove restriction of copy size for inter-server copy.Dai Ngo
Currently inter-server copy is allowed only if the copy size is larger than (rsize*14) which is the over-head of the mount operation of the source export. This patch, relying on the delayed unmount feature, removes this restriction since the mount and unmount overhead is now not applicable for every inter-server copy.

2021-08-10NFS: Add a private local dispatcher for NFSv4 callback operationsChuck Lever

2021-08-10SUNRPC: Set rq_auth_stat in the pg_authenticate() calloutChuck Lever
In a few moments, rq_auth_stat will need to be explicitly set to rpc_auth_ok before execution gets to the dispatcher. svc_authenticate() already sets it, but it often gets reset to rpc_autherr_badcred right after that call, even when authentication is successful. Let's ensure that the pg_authenticate callout and svc_set_client() set it properly in every case.

2021-08-10SUNRPC: Add svc_rqst::rq_auth_statChuck Lever
I'd like to take commit 4532608d71c8 ("SUNRPC: Clean up generic dispatcher code") even further by using only private local SVC dispatchers for all kernel RPC services. This change would enable the removal of the logic that switches between svc_generic_dispatch() and a service's private dispatcher, and simplify the invocation of the service's pc_release method so that humans can visually verify that it is always invoked properly. All that will come later. First, let's provide a better way to return authentication errors from SVC dispatcher functions. Instead of overloading the dispatch method's *statp argument, add a field to struct svc_rqst that can hold an error value.

2021-08-09SUNRPC/xprtrdma: Fix reconnection lockingTrond Myklebust
The xprtrdma client code currently relies on the task that initiated the connect to hold the XPRT_LOCK for the duration of the connection attempt. If the task is woken early, due to some other event, then that lock could get released early. Avoid races by using the same mechanism that the socket code uses of transferring lock ownership to the RDMA connect worker itself. That frees us to call rpcrdma_xprt_disconnect() directly since we're now guaranteed exclusion w.r.t. other callers.

2021-08-09NFSv4/pnfs: The layout barrier indicate a minimal value for the seqidTrond Myklebust
The intention of the layout barrier is to ensure that we do not update the layout to match an older value than the current expectation.

2021-08-09NFSv4/pNFS: Always allow update of a zero valued layout barrierTrond Myklebust
A zero value for the layout barrier indicates that it has been cleared (since seqid '0' is an illegal value), so we should always allow it to be updated.

Since commit 2b28a7bee453 ("fs, nfs: convert pnfs_layout_hdr.plh_refcount from atomic_t to refcount_t") it has not been legal to bump a zero refcount, so the code that tries to allow it if the NFS_LSEG_VALID flag is still set would cause trouble.

2021-08-09NFSv4/pNFS: Fix a layoutget livelock loopTrond Myklebust
If NFS_LAYOUT_RETURN_REQUESTED is set, but there is no value set for the layout plh_return_seq, we can end up in a livelock loop in which every layout segment retrieved by a new call to layoutget is immediately invalidated by pnfs_layout_need_return(). To get around this, we should just set plh_return_seq to the current value of the layout stateid's seqid.

Clean up. Now that there is only one registration mode, there is only one target "post_send" method: frwr_send(). rpcrdma_post_sends() no longer adds much value, especially since all of its call sites ignore the return code value except to check if it's non-zero.

ib_post_send() does not disconnect the QP when it returns an immediate error. Thus, the code that posts LocalInv has to explicitly disconnect after an immediate error.

Prevent such a stuck server from pinning client resources indefinitely by ensuring that certain idempotent requests (such as NULL) can time out even if the connection is still operational.
