SUNRPC: Add tracking of RPC level errors

2019-04-25T18:18:13+00:00

Add variables to track RPC level errors so that we can distinguish between issue that arose in the RPC transport layer as opposed to those arising from the reply message. Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

SUNRPC: Refactor xprt_request_wait_receive()

2019-04-25T18:18:12+00:00

Convert the transport callback to actually put the request to sleep instead of just setting a timeout. This is in preparation for rpc_sleep_on_timeout(). Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

SUNRPC: fix uninitialized variable warning

2019-03-26T20:04:32+00:00

Avoid following compiler warning on uninitialized variable net/sunrpc/xprtsock.c: In function ‘xs_read_stream_request.constprop’: net/sunrpc/xprtsock.c:525:10: warning: ‘read’ may be used uninitialized in this function [-Wmaybe-uninitialized] return read; ^~~~ net/sunrpc/xprtsock.c:529:23: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized] return ret < 0 ? ret : read; ~~~~~~~~~~~~~~^~~~~~ Signed-off-by: Alakesh Haloi Signed-off-by: Trond Myklebust

SUNRPC: Fix a client regression when handling oversized replies

2019-03-15T17:06:21+00:00

If the server sends a reply that is larger than the pre-allocated buffer, then the current code may fail to register how much of the stream that it has finished reading. This again can lead to hangs.

SUNRPC: Convert remaining GFP_NOIO, and GFP_NOWAIT sites in sunrpc

2019-03-02T21:25:26+00:00

Convert the remaining gfp_flags arguments in sunrpc to standard reclaiming allocations, now that we set memalloc_nofs_save() as appropriate. Signed-off-by: Trond Myklebust

SUNRPC: Fix an Oops in udp_poll()

2019-02-26T11:33:02+00:00

udp_poll() checks the struct file for the O_NONBLOCK flag, so we must not call it with a NULL file pointer. Fixes: 0ffe86f48026 ("SUNRPC: Use poll() to fix up the socket requeue races") Signed-off-by: Trond Myklebust

Merge tag 'nfs-rdma-for-5.1-1' of git://git.linux-nfs.org/projects/anna/linux-nfs

SUNRPC: Remove the redundant 'zerocopy' argument to xs_sendpages()

2019-02-20T22:35:58+00:00

Signed-off-by: Trond Myklebust

SUNRPC: Further cleanups of xs_sendpages()

2019-02-20T22:35:58+00:00

Now that we send the pages using a struct msghdr, instead of using sendpage(), we no longer need to 'prime the socket' with an address for unconnected UDP messages. Signed-off-by: Trond Myklebust

SUNRPC: Convert socket page send code to use iov_iter()

2019-02-20T22:35:58+00:00

Simplify the page send code using iov_iter and bvecs. Signed-off-by: Trond Myklebust
