2008-02-01SUNRPC: Use unsigned string lengths in xdr_decode_string_inplaceChuck Lever
XDR strings, opaques, and net objects should all use unsigned lengths. To wit, RFC 4506 says: 4.2. Unsigned Integer An XDR unsigned integer is a 32-bit datum that encodes a non-negative integer in the range [0,4294967295]. ... 4.11. String The standard defines a string of n (numbered 0 through n-1) ASCII bytes to be the number n encoded as an unsigned integer (as described above), and followed by the n bytes of the string. After this patch, xdr_decode_string_inplace now matches the other XDR string and array helpers that take a string length argument. See: xdr_encode_opaque_fixed, xdr_encode_opaque, xdr_encode_array Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Acked-By: NeilBrown <neilb@suse.de> Signed-off-by: J.

2007-10-09SUNRPC: mark bulk read/write data in xdrbuf\"Talpey, Thomas\
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.

2007-07-19SUNRPC: move bkl locking and xdr proc invocation into a common helperJ. Bruce Fields
Since every invocation of xdr encode or decode functions takes the BKL now, there's a lot of redundant lock_kernel/unlock_kernel pairs that we can pull out into a common function. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2006-12-06SUNRPC: Rename skb_reader_t and friendsChuck Lever
Clean-up: hch suggested that the RPC client shouldn't pollute the name space used by the generic skb manipulation routines in net/core/skbuff.c. Rename a couple of types in xdr.h to adhere to this convention. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2006-12-06SUNRPC: skb_read_bits is the same as xs_tcp_copy_dataChuck Lever
Clean-up: eliminate xs_tcp_copy_data -- it's exactly the same logic as the common routine skb_read_bits. The UDP and TCP socket read code now share the same routine for copying data into an xdr_buf. Now that skb_read_bits() is exported, rename it to avoid confusing it with a generic skb_* function. As these functions are XDR-specific, they should not have names that suggest they are of generic use. Also rename skb_read_and_csum_bits() to be consistent.

2006-12-06rpc: move process_xdr_bufOlga Kornievskaia
Since process_xdr_buf() is useful outside of the kerberos-specific code, we move it to net/sunrpc/xdr.c, export it, and rename it in keeping with xdr_* naming convention of xdr.c. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2006-10-17[PATCH] knfsd: Allow lockd to drop replies as appropriateNeilBrown
It is possible for the ->fopen callback from lockd into nfsd to find that an answer cannot be given straight away (an upcall is needed) and so the request has to be 'dropped', to be retried later. That error status is not currently propagated back. So: Change nlm_fopen to return nlm error codes (rather than a private protocol) and define a new nlm_drop_reply code. Cause nlm_drop_reply to cause the rpc request to get rpc_drop_reply when this error comes back. Cause svc_process to drop a request which returns a status of rpc_drop_reply.

2006-01-06NFS: support large reads and writes on the wireChuck Lever
Most NFS server implementations allow up to 64KB reads and writes on the wire. The Solaris NFS server allows up to a megabyte, for instance. Now the Linux NFS client supports transfer sizes up to 1MB, too. This will help reduce protocol and context switch overhead on read/write intensive NFS workloads, and support larger atomic read and write operations on servers that support them. Test-plan: Connectathon and iozone on mount point with wsize=rsize>32768 over TCP. Tests with NFS over UDP to verify the maximum RPC payload size cap.

2005-09-23[PATCH] RPC: introduce client-side transport switchChuck Lever
Move the bulk of client-side socket-specific code into a separate source file, net/sunrpc/xprtsock.c. Test-plan: Millions of fsx operations. Performance characterization such as "sio" or "iozone". Destructive testing (unplugging the network temporarily, server reboots). Connectathon with v2, v3, and v4.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
