* nfs: make nfs4_init_uniform_client_string use a dynamically allocated bufferJeff Layton2015-06-161-6/+0Star
| | | | | | | | | | | | | | Change the uniform client string generator to dynamically allocate the NFSv4 client name string buffer. With this patch, we can eliminate the buffers that are embedded within the "args" structs and simply use the name string that is hanging off the client. This uniform string case is a little simpler than the nonuniform since we don't need to deal with RCU, but we do have two different cases, depending on whether there is a uniquifier or not.

* nfs: convert setclientid and exchange_id encoders to use clp->cl_owner_idJeff Layton2015-06-161-1/+1
| | | | | | | | | | | | | | | ...instead of buffers that are part of their arg structs. We already hold a reference to the client, so we might as well use the allocated buffer. In the event that we can't allocate the clp->cl_owner_id, then just return -ENOMEM. Note too that we switch from a GFP_KERNEL allocation here to GFP_NOFS. It's possible we could end up trying to do a SETCLIENTID or EXCHANGE_ID in order to reclaim some memory, and the GFP_KERNEL allocations in the existing code could cause recursion back into NFS reclaim.

* NFS: Don't zap caches on fallocate()Anna Schumaker2015-04-231-0/+4
| | | | | | | | | | | This patch adds a GETATTR to the end of ALLOCATE and DEALLOCATE operations so we can set the updated inode size and change attribute directly. DEALLOCATE will still need to release pagecache pages, so nfs42_proc_deallocate() now calls truncate_pagecache_range() before contacting the server.

* NFSv4.1: Ask for no delegation on OPEN if using O_DIRECTTrond Myklebust2015-02-041-0/+2
| | | | | | | | | | | | | | | | If we're using NFSv4.1, then we have the ability to let the server know whether or not we believe that returning a delegation as part of our OPEN request would be useful. The feature needs to be used with care, since the client sending the request doesn't necessarily know how other clients are using that file, and how they may be affected by the delegation. For this reason, our initial use of the feature will be to let the server know when the client believes that handing out a delegation would not be useful. The first application for this function is when opening the file using O_DIRECT. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

* | NFSv4: use exponential retry on NFS4ERR_DELAY for async requests.NeilBrown2014-09-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently asynchronous NFSv4 request will be retried with exponential timeout (from 1/10 to 15 seconds), but async requests will always use a 15second retry. Some "async" requests are really synchronous though. The async mechanism is used to allow the request to continue if the requesting process is killed. In those cases, an exponential retry is appropriate. For example, if two different clients both open a file and get a READ delegation, and one client then unlinks the file (while still holding an open file descriptor), that unlink will used the "silly-rename" handling which is async. The first rename will result in NFS4ERR_DELAY while the delegation is reclaimed from the other client. The rename will not be retried for 15 seconds, causing an unlink to take 15 seconds rather than 100msec. This patch only added exponential timeout for async unlink and async rename. Other async calls, such as 'close' are sometimes waited for so they might benefit from exponential timeout too.
