2009-06-18nfs41: Backchannel: update cb_sequence args and resultsRicardo Labiaga1-1/+1
Change the type of cs_addr and csr_status to 'struct sockaddr' and '__be32' since the cb_sequence processing function will use existing functionality that expects these types. Signed-off-by: Ricardo Labiaga <Ricardo.Labiaga@netapp.com> Signed-off-by: Benny Halevy <bhalevy@panasas.com>
2009-06-18nfs41: verify CB_SEQUENCE position in callback compoundBenny Halevy1-0/+8
CB_SEQUENCE must appear first in the callback compound RPC. If it is not the first operation NFS4ERR_SEQUENCE_POS must be returned. If the first operation ni the CB_COMPOUND is not CB_SEQUENCE then NFS4ERR_OP_NOT_IN_SESSION must be returned.

2009-06-18nfs41: consider minorversion in callback_xdr:process_opBenny Halevy1-14/+71
Note that this patch changes the nfsv4.0 behavior also when CONFIG_NFS_V4_1 is not defined where NFS4ERR_MINOR_VERS_MISMATCH will be returned if the client received a CB_COMPOUND with minorversion != 0. Previously, it would have returned NFS4ERR_OP_ILLEGAL for CB_SEQUENCE. (or if the server is broken and sent OP_CB_GETATTR or OP_CB_RECALL with minorversion!=0, they would have been processed normally.

2008-05-16NFSv4: Check the return value of decode_compound_hdr_arg()Trond Myklebust1-11/+11
If decode_compound_hdr_arg() returns a resource error, then we cannot proceed to process the callback. Return a 'GARBAGE_ARGS' rpc-level error to the caller instead. If, however, the minor version field is incorrect, then we need to propagate the resulting NFS4ERR_MINOR_VERS_MISMATCH error back as the compound status field (setting the nops field to 0). Finally, if encode_compound_hdr_res() returns an error, we need to return an RPC_SYSTEM_ERR to the caller. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2007-02-12[PATCH] knfsd: SUNRPC: Provide room in svc_rqst for larger addressesChuck Lever1-2/+2
Expand the rq_addr field to allow it to contain larger addresses. Specifically, we replace a 'sockaddr_in' with a 'sockaddr_storage', then everywhere the 'sockaddr_in' was referenced, we use instead an accessor function (svc_addr_in) which safely casts the _storage to _in.

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!
