* [PATCH] vfs: *at functions: coreUlrich Drepper2006-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is a series of patches which introduce in total 13 new system calls which take a file descriptor/filename pair instead of a single file name. These functions, openat etc, have been discussed on numerous occasions. They are needed to implement race-free filesystem traversal, they are necessary to implement a virtual per-thread current working directory (think multi-threaded backup software), etc. We have in glibc today implementations of the interfaces which use the /proc/self/fd magic. But this code is rather expensive. Here are some results (similar to what Jim Meyering posted before). The test creates a deep directory hierarchy on a tmpfs filesystem. Then rm -fr is used to remove all directories. Without syscall support I get this: real 0m31.921s user 0m0.688s sys 0m31.234s With syscall support the results are much better: real 0m20.699s user 0m0.536s sys 0m20.149s The interfaces are for obvious reasons currently not much used. But they'll be used. coreutils (and Jeff's posixutils) are already using them. Furthermore, code like ftw/fts in libc (maybe even glob) will also start using them. I expect a patch to make follow soon. Every program which is walking the filesystem tree will benefit.

* [PATCH] knfsd: Provide missing NFSv2 part of patch for checking vfs_getattr.David Shaw2006-01-18
| | | | | | | | | | | | | | A recent patch which checked the return status of vfs_getattr in nfsd, completely missed the nfsproc.c (NFSv2) part. Here is it. This patch moved the call to vfs_getattr from the xdr encoding (at which point it is too late to return an error) to the call handling. This means several calls to vfs_getattr are needed in nfsproc.c. Many are encapsulated in nfsd_return_attrs and nfsd_return_dirop.

| | | | | | | | | | | | | | | | | | | | | | nfsd_sync* return an errno, which usually needs to be converted to an errno, sometimes immediately, sometimes a little later. Also, nfsd_setattr returns an nfserr which SHOULDN'T be converted from an errno (because it isn't one). Also some tidyups of the form: err = XX err = nfserrno(err) and err = XX if (err) err = nfserrno(err) become err = nfserrno(XX) Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] nfsd4: don't create on open that fails due to ERR_GRACEJ. Bruce Fields2006-01-18
| | | | | | | | | | | | | | | | | | In an earlier patch (commit b648330a1d741d5df8a5076b2a0a2519c69c8f41) I noted that a too-early grace-period check was preventing us from bumping the sequence id on open. Unfortunately in that patch I stupidly moved the grace-period check back too far, so now an open for create can succesfully create the file while still returning ERR_GRACE. The correct place for that check is after we've set the open_owner and handled any replays, but before we actually start mucking with the filesystem. Thanks to Avishay Traeger for reporting the bug.

| | | | | | | | | | | | | | | | | | | | | Fix race in setting bitfields of fuse_conn. Spotted by Andrew Morton. The two fields ->connected and ->mounted were always changed with the fuse_lock held. But other bitfields in the same structure were changed without the lock. In theory this could lead to losing the assignment of even the ones under lock. The chosen solution is to change these two fields to be a full unsigned type. The other bitfields aren't "important" enough to warrant the extra complexity of full locking or changing them to bitops. For all bitfields document why they are safe wrt. concurrent assignments. Also make the initialization of the 'num_waiting' atomic counter explicit.

| | | | | | | | | | | | | | | | | | | | Add ability to abort a filesystem connection. With the introduction of asynchronous reads, the ability to interrupt any request is not enough to dissolve deadlocks, since now waiting for the request completion (page unlocked) is independent of the actual request, so in a deadlock all threads will be uninterruptible. The solution is to make it possible to abort all requests, even those currently undergoing I/O to/from userspace. The natural interface for this is 'mount -f mountpoint', but that only works as long as the filesystem is attached. So also add an 'abort' attribute to the sysfs view of the connection.
