[PATCH] knfsd: Fix some minor sign problems in nfsd/xdr

2005-11-07T15:53:48Z

There are a couple of tests which could possibly be confused by extremely large numbers appearing in 'xdr' packets. I think the closest to an exploit you could get would be writing random data from a free page into a file - i.e. leak data out of kernel space. I'm fairly sure they cannot be used for remote compromise. Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: Allow run-time selection of NFS versions to export

2005-11-07T15:53:48Z

Provide a file in the NFSD filesystem that allows setting and querying of which version of NFS are being exported. Changes are only allowed while no server is running. Signed-off-by: Steve Dickson Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] nfsd4: move replay_owner

2005-09-13T15:22:31Z

It seems more natural to move the setting of the replay_owner into the relevant procedure instead of doing it in nfsv4_proc_compound. Signed-off-by: J. Bruce Fields Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] nfsd4: check lock type against openmode.

2005-07-08T01:24:11Z

We shouldn't be allowing, e.g., write locks on files not open for read. To enforce this, we add a pointer from the lock stateid back to the open stateid it came from, so that the check will continue to be correct even after the open is upgraded or downgraded.

[PATCH] nfsd4: return better error on io incompatible with open mode

2005-07-08T01:24:09Z

from RFC 3530: "Share reservations are established by OPEN operations and by their nature are mandatory in that when the OPEN denies READ or WRITE operations, that denial results in such operations being rejected with error NFS4ERR_LOCKED." (Note that share_denied is really only a legal error for OPEN.) Signed-off-by: Andy Adamson Signed-off-by: J.

[PATCH] nfsd4: seqid comments

2005-07-08T01:24:09Z

Add some comments on the use of so_seqid, in an attempt to avoid some of the confusion outlined in the previous patch.... Signed-off-by: J. Bruce Fields Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] nfsd4: fix sync'ing of recovery directory

2005-07-08T01:24:07Z

We need to fsync the recovery directory after writing to it, but we weren't doing this correctly. (For example, we weren't taking the i_sem when calling ->fsync().) Just reuse the existing nfsd fsync code instead. Signed-off-by: J. Bruce Fields Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: nfsd4 reboot dirname fix

2005-06-24T07:06:36Z

Set the recovery directory via /proc/fs/nfsd/nfs4recoverydir. It may be changed any time, but is used only on startup. Signed-off-by: Andy Adamson Signed-off-by: J. Bruce Fields Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: nfsd4: reboot recovery

2005-06-24T07:06:36Z

This patch adds the code to create and remove client subdirectories from the recovery directory, as described in the previous patch comment. Signed-off-by: Andy Adamson Signed-off-by: J. Bruce Fields Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: nfsd4: initialize recovery directory

2005-06-24T07:06:35Z

NFSv4 clients are required to know what state they have on the server so that they can reclaim it on server reboot. However, it is possible for pathalogical combinations of server reboots and network partitions to leave a client in a state where it cannot know whether it has lost its state on the server. For this reason, rfc3530 requires that we store some information about clients to stable storage. So we maintain a directory /var/lib/nfs/v4recovery with a subdirectory for each client with active state. We leave open the possibility of including files underneath each such subdirectory with information about the client, but for now the subdirectories are empty. We create a client subdirectory whenever a client makes its first non-reclaim open_confirm. We remove a client subdirectory whenever either a) its lease expires, or b) the grace period ends without it reclaiming anything. When handling reclaims, we allow the reclaim if and only if the client doing the reclaim has a subdirectory. This patch adds just the code to scan the recovery directory on nfsd startup.
