5c04c46aec [PATCH] knfsd: nfsd: mark rqstp to prevent use of sendfile in privacy case
Add a rq_sendfile_ok flag to svc_rqst which will be cleared in the privacy
case so that the wrapping code will get copies of the read data instead of
real page cache pages.  This makes life simpler when we encrypt the response.

6f54e2d0d3 [PATCH] knfsd: svcrpc: WARN() instead of returning an error from svc_take_page
Every caller of svc_take_page ignores its return value and assumes it
succeeded.  So just WARN() instead of returning an ignored error.  This would
have saved some time debugging a recent nfsd4 problem.

If there are still failure cases here, then the result is probably that we
overwrite an earlier part of the reply while xdr-encoding.

While the corrupted reply is a nasty bug, it would be worse to panic here and
create the possibility of a remote DOS; hence WARN() instead of BUG().

1918e34138 [PATCH] svcrpc: save and restore the daddr field when request deferred
The server code currently keeps track of the destination address on every
request so that it can reply using the same address.  However we forget to do
that in the case of a deferred request.  Remedy this oversight.  >From folks
at PolyServe.

0ba7536d5d [PATCH] knfsd: Fix some minor sign problems in nfsd/xdr
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.

a257cdd0e2 [PATCH] NFSD: Add server support for NFSv3 ACLs.
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.

9ba02638e4 [PATCH] RPC: Allow the sunrpc server to multiplex serveral programs on a single port
The NFS and NFSACL programs run on the same RPC transport.  This patch adds
 support for this by converting svc_program into a chained list of programs
 (server-side).

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
