Chuck Lever	c8aacb4d02	svcrdma: Fix leak of svc_rdma_recv_ctxt objects ... commit 23cf1ee1f1869966b75518c59b5cbda4c6c92450 upstream. Utilize the xpo_release_rqst transport method to ensure that each rqstp's svc_rdma_recv_ctxt object is released even when the server cannot return a Reply for that rqstp. Without this fix, each RPC whose Reply cannot be sent leaks one svc_rdma_recv_ctxt. This is a 2.5KB structure, a 4KB DMA-mapped Receive buffer, and any pages that might be part of the Reply message. The leak is infrequent unless the network fabric is unreliable or Kerberos is in use, as GSS sequence window overruns, which result in connection loss, are more common on fast transports.

Trond Myklebust	9372a40b54	SUNRPC: Fix priority queue fairness ... [ Upstream commit f42f7c283078ce3c1e8368b140e270755b1ae313 ] Fix up the priority queue to not batch by owner, but by queue, so that we allow '1 << priority' elements to be dequeued before switching to the next priority queue. The owner field is still used to wake up requests in round robin order by owner to avoid single processes hogging the RPC layer by loading the queues.

Benjamin Coddington	2440f3cebc	SUNRPC: Always drop the XPRT_LOCK on XPRT_CLOSE_WAIT ... This patch is only appropriate for stable kernels v4.16 - v4.19 Since commit 9b30889c54 ("SUNRPC: Ensure we always close the socket after a connection shuts down"), and until commit c544577daddb ("SUNRPC: Clean up transport write space handling"), it is possible for the NFS client to spin in the following tight loop: 269.964083: rpc_task_run_action: task:43@0 flags=5a81 state=0005 status=0 action=call_bind [sunrpc] 269.964083: rpc_task_run_action: task:43@0 flags=5a81 state=0005 status=0 action=call_connect [sunrpc] 269.964083: rpc_task_run_action: task:43@0 flags=5a81 state=0005 status=0 action=call_transmit [sunrpc] 269.964085: xprt_transmit: peer=[10.0.1.82]:2049 xid=0x761d3f77 status=-32 269.964085: rpc_task_run_action: task:43@0 flags=5a81 state=0005 status=-32 action=call_transmit_status [sunrpc] 269.964085: rpc_task_run_action: task:43@0 flags=5a81 state=0005 status=-32 action=call_status [sunrpc] 269.964085: rpc_call_status: task:43@0 status=-32 The issue is that the path through call_transmit_status does not release the XPRT_LOCK when the transmit result is -EPIPE, so the socket cannot be properly shut down. The below commit fixed things up in mainline by unconditionally calling xprt_end_transmit() and releasing the XPRT_LOCK after every pass through call_transmit. However, the entirety of this commit is not appropriate for stable kernels because its original inclusion was part of a series that modifies the sunrpc code to use a different queueing model. As a result, there are machinations within this patch that are not needed for a stable fix and will not make sense without a larger backport of the mainline series. In this patch, we take the slightly modified bit of the mainline patch below, which is to release the XPRT_LOCK on transmission error should we detect that the transport is waiting to close. commit c544577daddb618c7dd5fa7fb98d6a41782f020e upstream Author: Trond Myklebust <trond.myklebust@hammerspace.com> Date: Mon Sep 3 23:39:27 2018 -0400 SUNRPC: Clean up transport write space handling Treat socket write space handling in the same way we now treat transport congestion: by denying the XPRT_LOCK until the transport signals that it has free buffer space.

Vasily Averin	44e7bab39f	sunrpc: use-after-free in svc_process_common() ... commit d4b09acf924b84bae77cad090a9d108e70b43643 upstream. if node have NFSv41+ mounts inside several net namespaces it can lead to use-after-free in svc_process_common() svc_process_common() /* Setup reply header */ rqstp->rq_xprt->xpt_ops->xpo_prep_reply_hdr(rqstp); <<< HERE svc_process_common() can use incorrect rqstp->rq_xprt, its caller function bc_svc_process() takes it from serv->sv_bc_xprt. The problem is that serv is global structure but sv_bc_xprt is assigned per-netnamespace. According to Trond, the whole "let's set up rqstp->rq_xprt for the back channel" is nothing but a giant hack in order to work around the fact that svc_process_common() uses it to find the xpt_ops, and perform a couple of (meaningless for the back channel) tests of xpt_flags. All we really need in svc_process_common() is to be able to run rqstp->rq_xprt->xpt_ops->xpo_prep_reply_hdr() Bruce J Fields points that this xpo_prep_reply_hdr() call is an awfully roundabout way just to do "svc_putnl(resv, 0);" in the tcp case. This patch does not initialiuze rqstp->rq_xprt in bc_svc_process(), now it calls svc_process_common() with rqstp->rq_xprt = NULL. To adjust reply header svc_process_common() just check rqstp->rq_prot and calls svc_tcp_prep_reply_hdr() for tcp case. To handle rqstp->rq_xprt = NULL case in functions called from svc_process_common() patch intruduces net namespace pointer svc_rqst->rq_bc_net and adjust SVC_NET() definition. Some other function was also adopted to properly handle described case.

Chuck Lever	11b4d66ea3	NFSD: Handle full-length symlinks ... I've given up on the idea of zero-copy handling of SYMLINK on the server side. This is because the Linux VFS symlink API requires the symlink pathname to be in a NUL-terminated kmalloc'd buffer. The NUL-termination is going to be problematic (watching out for landing on a page boundary and dealing with a 4096-byte pathname). I don't believe that SYMLINK creation is on a performance path or is requested frequently enough that it will cause noticeable CPU cache pollution due to data copies. There will be two places where a transport callout will be necessary to fill in the rqstp: one will be in the svc_fill_symlink_pathname() helper that is used by NFSv2 and NFSv3, and the other will be in nfsd4_decode_create().

Instead of assuming the pages are coming from rq_args.pages, have the caller pass in the page list. The immediate benefit is a reduction of code duplication. It also prevents the NFSv4 WRITE decoder from passing an empty vector element when the transport has provided the payload in the xdr_buf's page array.

Bill Baker	0f90be132c	NFSv4 client live hangs after live data migration recovery ... 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.

Dave Wysochanski	016583d703	sunrpc: Change rpc_print_iostats to rpc_clnt_show_stats and handle rpc_clnt clones ... 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.

Receive buffers are always the same size, but each Send WR has a variable number of SGEs, based on the contents of the xdr_buf being sent. While assembling a Send WR, keep track of the number of SGEs so that we don't exceed the device's maximum, or walk off the end of the Send SGE array. For now the Send path just fails if it exceeds the maximum. The current logic in svc_rdma_accept bases the maximum number of Send SGEs on the largest NFS request that can be sent or received. In the transport layer, the limit is actually based on the capabilities of the underlying device, not on properties of the Upper Layer Protocol.

Chuck Lever	eb5d7a622e	svcrdma: Allocate recv_ctxt's on CPU handling Receives ... There is a significant latency penalty when processing an ingress Receive if the Receive buffer resides in memory that is not on the same NUMA node as the the CPU handling completions for a CQ. The system administrator and the device driver determine which CPU handles completions. This CPU does not change during life of the CQ. Further the Upper Layer does not have any visibility of which CPU it is. Allocating Receive buffers in the Receive completion handler guarantees that Receive buffers are allocated on the preferred NUMA node for that CQ.

Chuck Lever	3316f06311	svcrdma: Persistently allocate and DMA-map Receive buffers ... The current Receive path uses an array of pages which are allocated and DMA mapped when each Receive WR is posted, and then handed off to the upper layer in rqstp::rq_arg. The page flip releases unused pages in the rq_pages pagelist. This mechanism introduces a significant amount of overhead. So instead, kmalloc the Receive buffer, and leave it DMA-mapped while the transport remains connected. This confers a number of benefits: * Each Receive WR requires only one receive SGE, no matter how large the inline threshold is. This helps the server-side NFS/RDMA transport operate on less capable RDMA devices. * The Receive buffer is left allocated and mapped all the time. This relieves svc_rdma_post_recv from the overhead of allocating and DMA-mapping a fresh buffer. * svc_rdma_wc_receive no longer has to DMA unmap the Receive buffer. It has to DMA sync only the number of bytes that were received. * svc_rdma_build_arg_xdr no longer has to free a page in rq_pages for each page in the Receive buffer, making it a constant-time function. * The Receive buffer is now plugged directly into the rq_arg's head[0].iov_vec, and can be larger than a page without spilling over into rq_arg's page list. This enables simplification of the RDMA Read path in subsequent patches. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.

Chuck Lever	1e5f416074	svcrdma: Simplify svc_rdma_recv_ctxt_put ... Currently svc_rdma_recv_ctxt_put's callers have to know whether they want to free the ctxt's pages or not. This means the human developers have to know when and why to set that free_pages argument. Instead, the ctxt should carry that information with it so that svc_rdma_recv_ctxt_put does the right thing no matter who is calling. We want to keep track of the number of pages in the Receive buffer separately from the number of pages pulled over by RDMA Read. This is so that the correct number of pages can be freed properly and that number is well-documented. So now, rc_hdr_count is the number of pages consumed by head[0] (ie., the page index where the Read chunk should start); and rc_page_count is always the number of pages that need to be released when the ctxt is put. The @free_pages argument is no longer needed. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>	2018-05-11 15:48:57 -04:00

The immediate benefits include: - one fewer data copies on transports that support DDP - consistent error checking across all versions - reduction of code duplication - support for both legal forms of SYMLINK requests on RDMA transports for all versions of NFS (in particular, NFSv2, for completeness) In the long term, this helper is an appropriate spot to perform a per-transport call-out to fill the pathname argument using, say, RDMA Reads. Filling the pathname in the proc function also means that eventually the incoming filehandle can be interpreted so that filesystem- specific memory can be allocated as a sink for the pathname argument, rather than using anonymous pages.

Chuck Lever	8154ef2776	NFSD: Clean up legacy NFS WRITE argument XDR decoders ... Move common code in NFSD's legacy NFS WRITE decoders into a helper. The immediate benefit is reduction of code duplication and some nice micro-optimizations (see below). In the long term, this helper can perform a per-transport call-out to fill the rq_vec (say, using RDMA Reads). The legacy WRITE decoders and procs are changed to work like NFSv4, which constructs the rq_vec just before it is about to call vfs_writev. Why? Calling a transport call-out from the proc instead of the XDR decoder means that the incoming FH can be resolved to a particular filesystem and file. This would allow pages from the backing file to be presented to the transport to be filled, rather than presenting anonymous pages and copying or flipping them into the file's page cache later. I also prefer using the pages in rq_arg.pages, instead of pulling the data pages directly out of the rqstp::rq_pages array. This is currently the way the NFSv3 write decoder works, but the other two do not seem to take this approach. Fixing this removes the only reference to rq_pages found in NFSD, eliminating an NFSD assumption about how transports use the pages in rq_pages. Lastly, avoid setting up the first element of rq_vec as a zero- length buffer. This happens with an RDMA transport when a normal Read chunk is present because the data payload is in rq_arg's page list (none of it is in the head buffer).
