2005-03-11[PATCH] RPC: remove bogus atomic_dec in auth_nullTrond Myklebust
The atomic_dec in nul_destroy() is harmless, but can trigger an underflow error if the atomic_dec_and_test() debugging is turned on.

2005-03-10NFS,RPC: RPC client now advertises maximum payload sizeTrond Myklebust
The RPC client now reports the maximum payload size supported by the chosen transport method. This is something a little less than 64KB for RPC over UDP, and about 2GB - 1 for RPC over TCP. The effective rsize and wsize values are not allowed to exceed the reported maximum RPC payload size.

2005-03-10RPC: Don't kill timers when calling rpc_restart_call() after rpc_delay()Trond Myklebust
Currently, if we restart an RPC call after having set an RPC delay (for instance in the case where an NFS EJUKEBOX error has occurred) the call to rpc_delete_timer() at the top of the rpc_execute() loop will kill off our timer. This patch causes rpc_delete_timer() to detect if the rpc_task is still queued on a wait queue, and refuse to delete the timer if this is the case. Problem diagnosed by Jan Sanislo and Olaf Kirch.

2005-03-04[PATCH] nfsd: discard CACHE_HASHED flag, keeping information in refcount ↵Neil Brown
instead. This patch should fix a problem that has been experienced on at-least one busy NFS server, but it has not had lots of testing yet. If -mm could provide that ..... The rpc auth cache currently differentiates between a reference due to being in a hash chain (signalled by CACHE_HASHED flag) and any other reference (counted in refcnt). This is an artificial difference due to an historical accident, and it makes cache_put unsafe. This patch removes the distinction so now existance in a hash chain is counted just like any other reference. Thus a race window in cache_put is closed.

2005-03-04[PATCH] nfsd: nfsd: remove pg_authenticate fieldNeil Brown

2005-03-04[PATCH] nfsd: svcrpc: move export table checks to a per-program ↵Neil Brown
pg_add_client method svcauth_null_accept() and svcauth_unix_accept() are currently hard-wired to check the source ip address on an incoming request against the export table, which make sense for nfsd but not necessarily for other rpc-based services. So instead we have the accept() method call a program-specific pg_authenticate() method. We also move the call to this method into svc_process instead of calling it from the flavor-specific accept() routines. Signed-off-by: J.

2005-01-04[PATCH] Sync in core time granuality with filesystemsAndi Kleen
This patch corrects a problem that was originally added with the nanosecond timestamps in stat patch. The problem is that some file systems don't have enough space in their on disk inode to save nanosecond timestamps, so they truncate the c/a/mtime to seconds when flushing an dirty node. In core the inode would have full jiffies granuality. This can be observed by programs as a timestamp that jumps backwards under specific loads when an inode is flushed and then reloaded from disk. The problem was already known when the original patch went in, but it wasn't deemed important enough at that time. So far there has been only one report of it causing problems. Now Tridge is worried that it will break running Excel over samba4 because Excel seems to do very anal timestamp checking and samba4 will supply 100ns timestamps over the network. This patch solves it by putting the time resolution into the superblock of a fs and always rounding the in core timestamps to that granuality. This also supercedes some previous ext2/3 hacks to flush the inode less often when only the subsecond timestamp changes. I tried to keep the overhead low, in particular it tries to keep divisions out of fast paths as far as possible. The patch is quite big but 99% of it is just relatively straight forward search'n'replace in a lot of fs. Unconverted filesystems will default to a 1ns granuality, but may still show the problem if they continue to use CURRENT_TIME. I converted all in tree fs. One possible future extension of this would be to have two time granualities per superblock - one that specifies the visible resolution, and the other to specify how often timestamps should be flushed to disk, which could be tuned with a mount option per fs (e.g. often m/atimes don't need to be flushed every second). Would be easy to do as an addon if someone is interested. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
