NFS: Clean up process of marking inode stale.

2020-04-06T17:56:33Z

Instead of the various open coded calls to set the NFS_INO_STALE bit and call nfs_zap_caches(), consolidate them into a single function nfs_set_inode_stale(). Signed-off-by: Trond Myklebust

NFS: alloc_nfs_open_context() must use the file cred when available

2020-03-16T12:34:28Z

If we're creating a nfs_open_context() for a specific file pointer, we must use the cred assigned to that file. Fixes: a52458b48af1 ("NFS/NFSD/SUNRPC: replace generic creds with 'struct cred'.") Signed-off-by: Trond Myklebust

NFSv4: Fix revalidation of dentries with delegations

2020-02-12T18:55:25Z

If a dentry was not initially looked up while we were holding a delegation, then we do still need to revalidate that it still holds the same name. If there are multiple hard links to the same file, then all the hard links need validation.

NFS: nfs_find_open_context() should use cred_fscmp()

2020-02-03T21:35:07Z

We want to find open contexts that match our filesystem access properties. They don't have to exactly match the cred. Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

NFS: Add mount option 'softreval'

2020-01-15T15:54:33Z

Add a mount option 'softreval' that allows attribute revalidation 'getattr' calls to time out, and causes them to fall back to using the cached attributes. The use case for this option is for ensuring that we can still (slowly) traverse paths and use cached information even when the server is down. Once the server comes back up again, the getattr calls start succeeding, and the caches will revalidate as usual. The 'softreval' mount option is automatically enabled if you have specified 'softerr'. It can be turned off using the options 'nosoftreval', or 'hard'.

NFS: Convert struct nfs_fattr to use struct timespec64

2019-11-04T02:28:44Z

NFSv4 supports 64-bit times, so we should switch to using struct timespec64 when decoding attributes. Signed-off-by: Trond Myklebust

NFS: Fix inode fileid checks in attribute revalidation code

2019-09-02T17:10:19Z

We want to throw out the attrbute if it refers to the mounted on fileid, and not the real fileid. However we do not want to block cache consistency updates from NFSv4 writes.

NFS: Don't refresh attributes with mounted-on-file information

2019-08-19T12:56:04Z

If we've been given the attributes of the mounted-on-file, then do not use those to check or update the attributes on the application-visible inode. Signed-off-by: Trond Myklebust

NFS: Add deferred cache invalidation for close-to-open consistency violations

2019-07-06T18:54:49Z

If the client detects that close-to-open cache consistency has been violated, and that the file or directory has been changed on the server, then do a cache invalidation when we're done working with the file. The reason we don't do an immediate cache invalidation is that we want to avoid performance problems due to false positives. Also, note that we cannot guarantee cache consistency in this situation even if we do invalidate the cache. Signed-off-by: Trond Myklebust
