* knfsd: clean up nfsd filesystem interfacesJeff Layton2008-06-231-13/+53
| | | | | | | | | | | | | | | | | | Several of the nfsd filesystem interfaces allow changes to parameters that don't have any effect on a running nfsd service. They are only ever checked when nfsd is started. This patch fixes it so that changes to those procfiles return -EBUSY if nfsd is already running to make it clear that changes on the fly don't work. The patch should also close some relatively harmless races between changing the info in those interfaces and starting nfsd, since these variables are being moved under the protection of the nfsd_mutex. Finally, the nfsv4recoverydir file always returns -EINVAL if read. This patch fixes it to return the recoverydir path as expected. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J.

* lockd: unlock lockd locks associated with a given server ipWendy Cheng2008-04-251-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For high-availability NFS service, we generally need to be able to drop file locks held on the exported filesystem before moving clients to a new server. Currently the only way to do that is by shutting down lockd entirely, which is often undesireable (for example, if you want to continue exporting other filesystems). This patch allows the administrator to release all locks held by clients accessing the client through a given server ip address, by echoing that address to a new file, /proc/fs/nfsd/unlock_ip, as in: shell> echo 10.1.1.2 > /proc/fs/nfsd/unlock_ip The expected sequence of events can be: 1. Tear down the IP address 2. Unexport the path 3. Write IP to /proc/fs/nfsd/unlock_ip to unlock files 4. Signal peer to begin take-over. For now we only support IPv4 addresses and NFSv2/v3 (NFSv4 locks are not affected). Also, if unmounting the filesystem is required, we assume at step 3 that clients using the given server ip are the only clients holding locks on the given filesystem; otherwise, an additional patch is required to allow revoking all locks held by lockd on a given filesystem.

| | | | | | | | | | | | | | | Neil Brown points out that we're checking buf[size-1] in a couple places without first checking whether size is zero. Actually, given the implementation of simple_transaction_get(), buf[-1] is zero, so in both of these cases the subsequent check of the value of buf[size-1] will catch this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the write handler for the portlist file to allow creating new listening endpoints on a transport.

Transports can also be removed as follows: '-'<transport_name><space><port number> For example: echo "-tcp 2049" > /proc/fs/nfsd/portlist Attempting to add a listener with an invalid transport string results in EPROTONOSUPPORT and a perror string of "Protocol not supported".

Better to just fail immediately: the failure is then much easier to understand and debug, and it could save us complexity in some later code. (But actually, it doesn't help currently because the cache is also turned off in some odd failure cases; we should probably find a better way to handle those failure cases some day.)

* [PATCH] VFS: Permit filesystem to override root dentry on mountDavid Howells2006-06-231-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the get_sb() filesystem operation to take an extra argument that permits the VFS to pass in the target vfsmount that defines the mountpoint. The filesystem is then required to manually set the superblock and root dentry pointers. For most filesystems, this should be done with simple_set_mnt() which will set the superblock pointer and then set the root dentry to the superblock's s_root (as per the old default behaviour). The get_sb() op now returns an integer as there's now no need to return the superblock pointer. This patch permits a superblock to be implicitly shared amongst several mount points, such as can be done with NFS to avoid potential inode aliasing. In such a case, simple_set_mnt() would not be called, and instead the mnt_root and mnt_sb would be set directly. The patch also makes the following changes: (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount pointer argument and return an integer, so most filesystems have to change very little. (*) If one of the convenience function is not used, then get_sb() should normally call simple_set_mnt() to instantiate the vfsmount. This will always return 0, and so can be tail-called from get_sb(). (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the dcache upon superblock destruction rather than shrink_dcache_anon(). This is required because the superblock may now have multiple trees that aren't actually bound to s_root, but that still need to be cleaned up. The currently called functions assume that the whole tree is rooted at s_root, and that anonymous dentries are not the roots of trees which results in dentries being left unculled. However, with the way NFS superblock sharing are currently set to be implemented, these assumptions are violated: the root of the filesystem is simply a dummy dentry and inode (the real inode for '/' may well be inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries with child trees. [*] Anonymous until discovered from another tree. (*) The documentation has been adjusted, including the additional bit of changing ext2_* into foo_* in the documentation.

* [PATCH] knfsd: Restore functionality to read from file in /proc/fs/nfsd/NeilBrown2005-11-071-1/+15
| | | | | | | | | | | | | | | | Most files in the nfsd filesystems are transaction files. You write a request, and read a response. For some (e.g. 'threads') it makes sense to just be able to read and get the current value. This functionality did exist but was broken recently when someone modified nfsctl.c without going through the maintainer. This patch fixes the regression.

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!
