* NFS: "[no]resvport" mount option changes mountd client tooChuck Lever2008-12-23
| | | | | | | | | | If the admin has specified the "noresvport" option for an NFS mount point, the kernel's NFS client uses an unprivileged source port for the main NFS transport. The kernel's mountd client should use an unprivileged port in this case as well. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: introduce nfs_mount_info struct for calling nfs_mount()Chuck Lever2008-12-23
| | | | | | | | Clean up: convert nfs_mount() to take a single data structure argument to make it simpler to add more arguments. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Client mounts hang when exported directory do not existSteve Dickson2008-10-07
| | | | | | | | | | | | | | | | | | | | This patch fixes a regression that was introduced by the string based mounts. nfs_mount() statically returns -EACCES for every error returned by the remote mounted. This is incorrect because -EACCES is an non-fatal error to the mount.nfs command. This error causes mount.nfs to retry the mount even in the case when the exported directory does not exist. This patch maps the errors returned by the remote mountd into valid errno values, exactly how it was done pre-string based mounts. By returning the correct errno enables mount.nfs to do the right thing. Signed-off-by: Steve Dickson <steved@redhat.com> [Trond.Myklebust@netapp.com: nfs_stat_to_errno() now correctly returns negative errors, so remove the sign change.] Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFS: Switch from intr mount option to TASK_KILLABLEMatthew Wilcox2007-12-06
| | | | | | | | | By using the TASK_KILLABLE infrastructure, we can get rid of the 'intr' mount option. We have to use _killable everywhere instead of _interruptible as we get rid of rpc_clnt_sigmask/sigunmask. Signed-off-by: Liam R.

* NFS: Remake nfsroot_mount as a permanent part of NFS clientChuck Lever2007-07-10
| | | | | | | | | | | | In preparation for supporting NFSv2 and NFSv3 mount option handling in the kernel NFS client, convert mount_clnt.c to be a permanent part of the NFS client, instead of built only when CONFIG_ROOT_NFS is enabled. In addition, we also replace the "struct sockaddr_in *" argument with something more generic, to help support IPv6 at some later point.

* SUNRPC: Add a convenient default for the hostname when calling rpc_create()Chuck Lever2007-07-10
| | | | | | | | | A couple of callers just use a stringified IP address for the rpc client's hostname. Move the logic for constructing this into rpc_create(), so it can be shared. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* SUNRPC: RPC buffer size estimates are too largeChuck Lever2007-05-01
| | | | | | | | | | | | | | | | | | | 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>

| * SUNRPC: eliminate rpc_call()Chuck Lever2006-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean-up: replace rpc_call() helper with direct call to rpc_call_sync. This makes NFSv2 and NFSv3 synchronous calls more computationally efficient, and reduces stack consumption in functions that used to invoke rpc_call more than once. Test plan: Compile kernel with CONFIG_NFS enabled. Connectathon on NFS version 2, version 3, and version 4 mount points.

| * SUNRPC: display human-readable procedure name in rpc_iostats outputChuck Lever2006-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Test plan: Mount with NFSv2, NFSv3, and NFSv4, and do "cat /proc/self/mountstats". Signed-off-by: Chuck Lever <cel@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
