NFSv4: Express delegation limit in units of pages

2015-09-07T16:36:13+00:00

Since we're tracking modifications to the page cache on a per-page basis, it makes sense to express the limit to how much we may cache in units of pages. Signed-off-by: Trond Myklebust

NFS: Send attributes in OPEN request for NFS4_CREATE_EXCLUSIVE4_1

2015-08-27T23:47:07+00:00

Client sends a SETATTR request after OPEN for updating attributes. For create file with S_ISGID is set, the S_ISGID in SETATTR will be ignored at nfs server as chmod of no PERMISSION. v3, same as v2. Signed-off-by: Kinglong Mee Signed-off-by: Trond Myklebust

NFS: Get suppattr_exclcreat when getting server capabilities

2015-08-27T23:45:27+00:00

Create file with attributs as NFS4_CREATE_EXCLUSIVE4_1 mode depends on suppattr_exclcreat attribut. v3, same as v2. Signed-off-by: Kinglong Mee Signed-off-by: Trond Myklebust

NFSv4: Enable delegated opens even when reboot recovery is pending

2015-08-20T04:01:54+00:00

Unlike the previous attempt, this takes into account the fact that we may be calling it from the recovery thread itself. Detect this by looking at what kind of open we're doing, and checking the state of the NFS_DELEGATION_NEED_RECLAIM if it turns out we're doing a reboot reclaim-type open.

nfs: make nfs4_init_uniform_client_string use a dynamically allocated buffer

2015-06-16T15:15:51+00:00

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_id

2015-06-16T15:15:31+00:00

...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: increase size of EXCHANGE_ID name string buffer

2015-06-16T15:15:21+00:00

The current buffer is much too small if you have a relatively long hostname. Bring it up to the size of the one that SETCLIENTID has. Cc: Reported-by: Michael Skralivetsky Signed-off-by: Jeff Layton Signed-off-by: Trond Myklebust

NFS: Don't zap caches on fallocate()

2015-04-23T18:36:28+00:00

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: Allow getdeviceinfo to return notification info back to caller

2015-03-27T16:32:24+00:00

We are only allowed to cache deviceinfo if the server supports notifications and actually promises to call us back when changes occur. Right now, we request those notifications, but then we don't check the server's reply. Signed-off-by: Trond Myklebust
