fs: make helpers idmap mount aware

2021-01-24T13:27:20+00:00

Extend some inode methods with an additional user namespace argument. A filesystem that is aware of idmapped mounts will receive the user namespace the mount has been marked with. This can be used for additional permission checking and also to enable filesystems to translate between uids and gids if they need to. We have implemented all relevant helpers in earlier patches. As requested we simply extend the exisiting inode method instead of introducing new ones. This is a little more code churn but it's mostly mechanical and doesnt't leave us with additional inode methods.

stat: handle idmapped mounts

2021-01-24T13:27:17+00:00

The generic_fillattr() helper fills in the basic attributes associated with an inode. Enable it to handle idmapped mounts. If the inode is accessed through an idmapped mount map it into the mount's user namespace before we store the uid and gid. If the initial user namespace is passed nothing changes so non-idmapped mounts will see identical behavior as before.

NFS: fix nfs_path in case of a rename retry

2020-10-06T14:21:18+00:00

We are generating incorrect path in case of rename retry because we are restarting from wrong dentry. We should restart from the dentry which was received in the call to nfs_path. CC: stable@vger.kernel.org Signed-off-by: Ashish Sangwan Signed-off-by: Anna Schumaker

NFS: Add a module parameter to set nfs_mountpoint_expiry_timeout

2020-04-02T22:53:59+00:00

Setting nfs_mountpoint_expiry_timeout() to a negative value stops mountpoint expiration, while setting it to a positive value restarts the scheduler. Signed-off-by: Trond Myklebust

NFS: finish_automount() requires us to hold 2 refs to the mount record

2020-04-02T22:51:12+00:00

We must not return from nfs_d_automount() without holding 2 references to the mount record. Doing so, will trigger the BUG() in finish_automount(). Also ensure that we don't try to reschedule the automount timer with a negative or zero timeout value.

NFS: Don't hard-code the fs_type when submounting

2020-02-25T18:31:19+00:00

Hard-coding the fstype causes "nfs4" mounts to appear as "nfs", which breaks scripts that do "umount -at nfs4". Reported-by: Patrick Steinhardt Fixes: f2aedb713c28 ("NFS: Add fs_context support.") Signed-off-by: Scott Mayhew Signed-off-by: Anna Schumaker

NFS: Add softreval behaviour to nfs_lookup_revalidate()

2020-01-24T21:51:13+00:00

If the server is unavaliable, we want to allow the revalidating lookup to time out, and to default to validating the cached dentry if the 'softreval' mount option is set. Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker
