2005-06-22[PATCH] NFSD: Add server support for NFSv3 ACLs.Andreas Gruenbacher
This adds functions for encoding and decoding POSIX ACLs for the NFSACL protocol extension, and the GETACL and SETACL RPCs. The implementation is compatible with NFSACL in Solaris.

2005-06-22[PATCH] RPC: Allow the sunrpc server to multiplex serveral programs on a ↵Andreas Gruenbacher

support Ensure that we don't create an RPC client without checking that the server does indeed support the RPC program + version that we are trying to set up.

2005-03-30[PATCH] svcrpc: auth_domain documentationNeil Brown
The use of auth_domains is somewhat confusing, in part because they were originally intended to be used in a more general way than they currently are.

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.

2005-03-04[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.

2004-08-22[PATCH] nfsd: simplify auth_domain_lookupNeil Brown
The interface between the auth_domain and the cache code is messy; the auth_domain code is the only real user of the full 11-argument DefineCacheLookup, and does weird stuff with it (like passing in through one of the arguments a bit of code with a conditional return). We could further parametrize DefineCacheLookup, but I think it's already too complicated. My solution is to just ignore DefineCacheLookup and write the auth_domain_lookup function from scratch. It's actually a pretty short function (much simpler than DefineCacheLookup itself), and it's much easier to read this short function than it is to read some special-cased DefineCacheLookup to verify that it does what it says it does....

2004-08-22[PATCH] nfsd: make cache_init initialize reference count to 1Neil Brown
Presumably anyone creating a new cache entry is going to want a reference on that cache; and indeed every caller of cache_init increments the reference count immediately afterwards. So may as well make cache_init set an initial reference count of 1. Also, note that cache_init initializes the flags; callers don't need to. Signed-off-by: J.

2004-06-04[PATCH] kNFSd: gss_svc locking and refcounting fixesNeil Brown

2004-05-24[PATCH] Prevent scary warnings from knfsdAndrew Morton
From: "J. Bruce Fields" <bfields@fieldses.org> The kernel currently prints: nfsd: nobody listening for auth.unix.ip upcall; has some daemon not been started? on every bootup, during initscripts. Neil Brown <neilb@cse.unsw.edu.au> says: It was part of the recent set of idmapper patches. Bruce wanted the admin to get a warning when the idmapper daemon wasn't running. I thought the same warning should apply to any daemon that responded to upcalls. In the case of auth.unix.ip it isn't strictly necessary for a daemon to be running (for comparability with 2.4). You can get rid of the warning by doing: mount -t nfsd nfsd /proc/fs/nfs before mountd is started (init scripts should start doing this I hope, but distributions don't tend to use the init script from nfs-utils, so it is hard to push it). This will trigger mountd to listen on auth.unix.ip and others. That's a hassle, so Bruce's patch limits the warning purely to the new idmapper cache. It provides a callback in the cache_detail that individual caches can use to log messages when upcalls fail because a userspace daemon not running. Implement this method for the idmapping caches.
