* NFS: Use unsigned intermediates for manipulating header lengths (NFSv2 XDR)Chuck Lever2008-01-301-10/+14
| | | | | | | | Clean up: prevent length underflow and mixed sign comparisons when unmarshalling NFS version 2 read, readdir, and readlink replies. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: mark bulk read/write data in xdrbuf\"Talpey, Thomas\2007-10-091-0/+2
| | | | | | | | | | Adds a flag word to the xdrbuf struct which indicates any bulk disposition of the data. This enables RPC transport providers to marshal it efficiently/appropriately, and may enable other optimizations.

* NFS: Convert printk's to dprintk's in fs/nfs/nfs?xdr.cChuck Lever2007-10-091-9/+9
| | | | | | | | Due to recent edict to replace or remove printk's that can be triggered en masse by remote misbehavior. Left a few that only occur just before a BUG. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Introduce struct nfs_removeargs+nfs_removeresTrond Myklebust2007-07-191-3/+16
| | | | | | | We need a common structure for setting up an unlink() rpc call in order to fix the asynchronous unlink code. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Remove the tk_auth macro...Trond Myklebust2007-07-101-3/+3
| | | | | | | | We should almost always be deferencing the rpc_auth struct by means of the credential's cr_auth field instead of the rpc_clnt->cl_auth anyway. Fix up that historical mistake, and remove the macro that propagated it. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* SUNRPC: RPC buffer size estimates are too largeChuck Lever2007-04-301-5/+2
| | | | | | | | | | | | | | | | | | | The RPC buffer size estimation logic in net/sunrpc/clnt.c always significantly overestimates the requirements for the buffer size. A little instrumentation demonstrated that in fact rpc_malloc was never allocating the buffer from the mempool, but almost always called kmalloc. To compute the size of the RPC buffer more precisely, split p_bufsiz into two fields; one for the argument size, and one for the result size. Then, compute the sum of the exact call and reply header sizes, and split the RPC buffer precisely between the two. That should keep almost all RPC buffers within the 2KiB buffer mempool limit. And, we can finally be rid of RPC_SLACK_SPACE! Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFS: Use cached page as buffer for NFS symlink requestsChuck Lever2006-09-221-3/+18
| | | | | | | | | | | Now that we have a copy of the symlink path in the page cache, we can pass a struct page down to the XDR routines instead of a string buffer.

| | | | | | | | | | Trond had apparently merged the same patch twice, causing a duplicate include of the "internal.h" file, with resulting obvious confusion. Tssk.

(*) fs/nfs/super.c Superblock management functions for NFS and NFS4, normal access, clones and referrals. The NFS4 superblock functions _could_ move out into a separate conditionally compiled file, but it's probably not worth it as there're so many common bits. (*) fs/nfs/namespace.c Some namespace-specific functions have been moved here. (*) fs/nfs/nfs4namespace.c NFS4-specific namespace functions (this could be merged into the previous file). This file is conditionally compiled. (*) fs/nfs/internal.h Inter-file declarations, plus a few simple utility functions moved from fs/nfs/inode.c. Additionally, all the in-.c-file externs have been moved here, and those files they were moved from now includes this file. For the most part, the functions have not been changed, only some multiplexor functions have changed significantly. I've also: (*) Added some extra banner comments above some functions. (*) Rearranged the function order within the files to be more logical and better grouped (IMO), though someone may prefer a different order. (*) Reduced the number of #ifdefs in .c files. (*) Added missing __init and __exit directives. Signed-Off-By: David Howells <dhowells@redhat.com>

| * SUNRPC: display human-readable procedure name in rpc_iostats outputChuck Lever2006-03-201-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add fields to the rpc_procinfo struct that allow the display of a human-readable name for each procedure in the rpc_iostats output. Also fix it so that the NFSv4 stats are broken up correctly by sub-procedure number. NFSv4 uses only two real RPC procedures: NULL, and COMPOUND.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+711
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!
