Both the (recently introduces) nsm_sema and the older f_sema are converted over. Cc: Olaf Kirch Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: match GRANTED_RES replies using cookies

2006-10-04T14:55:18+00:00

When we send a GRANTED_MSG call, we current copy the NLM cookie provided in the original LOCK call - because in 1996, some broken clients seemed to rely on this bug. However, this means the cookies are not unique, so that when the client's GRANTED_RES message comes back, we cannot simply match it based on the cookie, but have to use the client's IP address in addition. Which breaks when you have a multi-homed NFS client. The X/Open spec explicitly mentions that clients should not expect the same cookie; so one may hope that any clients that were broken in 1996 have either been fixed or rendered obsolete.

[PATCH] knfsd: make nlmclnt_next_cookie SMP safe

2006-10-04T14:55:17+00:00

The way we incremented the NLM cookie in nlmclnt_next_cookie was not thread safe. This patch changes the counter to an atomic_t Signed-off-by: Olaf Kirch Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: lockd: optionally use hostnames for identifying peers

2006-10-04T14:55:17+00:00

This patch adds the nsm_use_hostnames sysctl and module param. If set, lockd will use the client's name (as given in the NLM arguments) to find the NSM handle. This makes recovery work when the NFS peer is multi-homed, and the reboot notification arrives from a different IP than the original lock calls.

[PATCH] knfsd: simplify nlmsvc_invalidate_all

2006-10-04T14:55:17+00:00

As a result of previous patches, the loop in nlmsvc_invalidate_all just sets h_expires for all client/hosts to 0 (though does it in a very complicated way). This was possibly meant to trigger early garbage collection but half the time '0' is in the future and so it infact delays garbage collection. Pre-aging the 'hosts' is not really needed at this point anyway so we throw out the loop and nlm_find_client which is no longer needed.

[PATCH] knfsd: lockd: make nlm_traverse_* more flexible

2006-10-04T14:55:17+00:00

This patch makes nlm_traverse{locks,blocks,shares} and friends use a function pointer rather than a "action" enum. This function pointer is given two nlm_hosts (one given by the caller, the other taken from the lock/block/share currently visited), and is free to do with them as it wants. If it returns a non-zero value, the lockd/block/share is released. Signed-off-by: Olaf Kirch Signed-off-by: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] knfsd: change nlm_file to use a hlist

2006-10-04T14:55:17+00:00

This changes struct nlm_file and the nlm_files hash table to use a hlist instead of the home-grown lists. This allows us to remove f_hash which was only used to find the right hash chain to delete an entry from. It also increases the size of the nlm_files hash table from 32 to 128.
