* SUNRPC xprtrdma: fix XDR tail buf marshalling for all opsJames Lentini2007-12-111-8/+1
| | | | | | | | | | | | | | | | | | rpcrdma_convert_iovs is passed an xdr_buf representing either an RPC request or an RPC reply. In the case of a request, several calculations and tests involving pos are unnecessary. In the case of a reply, several calculations and tests involving pos are incorrect (the code tests pos against the reply xdr buf's len field, which is always 0 at the time rpcrdma_convert_iovs is executed). This change removes the incorrect/unnecessary calculations and tests involving pos. This fixes an observed problem when reading certain file sizes over NFS/RDMA.

* | SUNRPC: remove NFS/RDMA client's binary sysctlsJames Lentini2007-11-261-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | Support for binary sysctls is being deprecated in 2.6.24. Since there are no applications using the NFS/RDMA client's binary sysctls, it makes sense to remove them. The patch below does this while leaving the /proc/sys interface unchanged.

|/ | | | | | | | | | | | | | | Instead of mapping all errors except EACCES to EAGAIN, map all errors except EAGAIN to EACCES. An example is user-land negotiating a Kerberos context with an encryption type that is not supported by the kernel code. (This can happen due to mis-configuration or a bug in the Kerberos code that does not honor our request to limit the encryption types negotiated.) This failure is not transient, and returning EAGAIN causes mount to continuously retry rather than giving up.

* [SG] Get rid of __sg_mark_end()Jens Axboe2007-11-021-3/+3
| | | | | | | | | | | | sg_mark_end() overwrites the page_link information, but all users want __sg_mark_end() behaviour where we just set the end bit. That is the most natural way to use the sg list, since you'll fill it in and then mark the end point. So change sg_mark_end() to only set the termination bit. Add a sg_magic debug check as well, and clear a chain pointer if it is set. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* [NET]: Fix incorrect sg_mark_end() calls.David S. Miller2007-10-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes scatterlist corruptions added by commit 68e3f5dd4db62619fdbe520d36c9ebf62e672256 [CRYPTO] users: Fix up scatterlist conversion errors The issue is that the code calls sg_mark_end() which clobbers the sg_page() pointer of the final scatterlist entry. The first part fo the fix makes skb_to_sgvec() do __sg_mark_end(). After considering all skb_to_sgvec() call sites the most correct solution is to call __sg_mark_end() in skb_to_sgvec() since that is what all of the callers would end up doing anyways. I suspect this might have fixed some problems in virtio_net which is the sole non-crypto user of skb_to_sgvec(). Other similar sg_mark_end() cases were converted over to __sg_mark_end() as well. Arguably sg_mark_end() is a poorly named function because it doesn't just "mark", it clears out the page pointer as a side effect, which is what led to these bugs in the first place. The one remaining plain sg_mark_end() call is in scsi_alloc_sgtable() and arguably it could be converted to __sg_mark_end() if only so that we can delete this confusing interface from linux/scatterlist.h Signed-off-by: David S.

| * SUNRPC: RPC bind failures should be permanent for NULL requestsChuck Lever2007-10-091-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of an RPC ping (a NULL request) is to determine whether the remote end is operating and supports the RPC program and version of the request. If we do an RPC bind and the remote's rpcbind service says "this program or service isn't supported" then we have our answer already, and we should give up immediately. This is good for the kernel mount client, as it will cause the request to fail, and then allow an immediate retry with different options.

| * SUNRPC: Split another new rpcbind retry error code from EACCESChuck Lever2007-10-092-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add more new error code processing to the kernel's rpcbind client and to call_bind_status() to distinguish two cases: Case 1: the remote has replied that the program/version tuple is not registered (returns EACCES) Case 2: retry with a lesser rpcbind version (rpcb now returns EPFNOSUPPORT) This change allows more specific error processing for each of these two cases. We now fail case 2 instead of retrying... it's a server configuration error not to support even rpcbind version 2. And don't expose this new error code to user land -- convert it to EIO before failing the RPC.

| * SUNRPC: Add a new error code for retry waiting for another binderChuck Lever2007-10-092-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new error code processing to the kernel's rpcbind client and to call_bind_status() to distinguish two cases: Case 1: the remote has replied that the program/version tuple is not registered (returns -EACCES) Case 2: another process is already in the middle of binding on this transport (now returns -EAGAIN) This change allows more specific retry processing for each of these two cases.
