* splice: handle try_to_release_page() failureJens Axboe2008-05-281-2/+3
| | | | | | | | splice currently assumes that try_to_release_page() always suceeds, but it can return failure. If it does, we cannot steal the page. Acked-by: Mingming Cao <cmm@us.ibm.com Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* posix timers: discard SI_TIMER signals on execOleg Nesterov2008-05-261-0/+1
| | | | | | | | | | | | | | | Based on Roland's patch. This approach was suggested by Austin Clements from the very beginning, and then by Linus. As Austin pointed out, the execing task can be killed by SI_TIMER signal because exec flushes the signal handlers, but doesn't discard the pending signals generated by posix timers. Perhaps not a bug, but people find this surprising.

* proc: proc_get_inode() should get module only onceDenis V. Lunev2008-05-241-1/+2
| | | | | | | | | | | | | | | | | | | | | Any file under /proc/net opened more than once leaked the refcounter on the module it belongs to. The problem is that module_get is called for each file opening while module_put is called only when /proc inode is destroyed. So, lets put module counter if we are dealing with already initialised inode. Addresses http://bugzilla.kernel.org/show_bug.cgi?id=10737 Signed-off-by: Denis V.

* fuse: fix bdi naming conflictMiklos Szeredi2008-05-241-1/+6
| | | | | | | | | | | | | | | | | | | Fuse allocates a separate bdi for each filesystem, and registers them in sysfs with "MAJOR:MINOR" of sb->s_dev (st_dev). This works fine for anon devices normally used by fuse, but can conflict with an already registered BDI for "fuseblk" filesystems, where sb->s_dev represents a real block device. In particularl this happens if a non-partitioned device is being mounted. Fix by registering with a different name for "fuseblk" filesystems. Thanks to Ioan Ionita for the bug report.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have multiple buffers in a single page for a blocksize == pagesize filesystem we might overwrite the page contents if two callers hit it shortly after each other.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | writeback If we allow memory reclaim to wait on the pages under writeback in inode cluster writeback we could deadlock because we are currently holding the ILOCK on the initial writeback inode which is needed in data I/O completion to change the file size or do unwritten extent conversion before the pages are taken out of writeback state.

| * [XFS] Fix fsync() b0rkage.David Chinner2008-05-234-86/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xfs_fsync() fails to wait for data I/O completion before checking if the inode is dirty or clean to decide whether to log the inode or not. This misses inode size updates when the data flushed by the fsync() is extending the file. Hence, like fdatasync(), we need to wait for I/o completion first, then check the inode for cleanliness. Doing so makes the behaviour of xfs_fsync() identical for fsync and fdatasync and we *always* use synchronous semantics if the inode is dirty. Therefore also kill the differences and remove the unused flags from the xfs_fsync function and callers.

I limited the new ones to values that are associated with the mount with the exception of "seal" (which is a per tree connection property, but I thought was important enough to show through). Eventually cifs's parse_mount_options also needs to be rewritten to use the match_token API but that would be a big enough change that I would prefer that changing parse_mount_options wait until next release.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do the following series of operations on a CIFS share: opendir(dir) readdir(dir) unlink(file in dir) rewinddir(dir) readdir(dir) If the readdir read all entries in the directory this will make CIFS throw an error like this: CIFS VFS: Send error in FindClose = -9 CIFS requests "Close at end of search" of the server by setting this bit when issuing FindFirst or FindNext. Therefore when all search entries are returned, the server may return "end of search" and close the search implicitly when this bit is set by the client on the request. We check for this when a readdir is explicitly closed - but when the client notices that a directory has changed after the last operation, we attempt to close the directory before reopening by reissuing a second FindFirst. But, the directory may already been implicitly closed (due to end of search) because the first readdir finished. So we only want to issue a FindClose call in this case when we don't expect it to already be closed. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

| * [CIFS] CIFS currently allows for permissions to be changed on files, evenJeff Layton2008-05-122-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | when unix extensions and cifsacl support are disabled. These permissions changes are "ephemeral" however. They are lost whenever a share is mounted and unmounted, or when memory pressure forces the inode out of the cache. Because of this, we'd like to introduce a behavior change to make CIFS behave more like local DOS/Windows filesystems. When unix extensions and cifsacl support aren't enabled, then don't silently ignore changes to permission bits that can't be reflected on the server. Still, there may be people relying on the current behavior for certain applications. This patch adds a new "dynperm" (and a corresponding "nodynperm") mount option that will be intended to make the client fall back to legacy behavior when setting these modes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | strlcpy is faster than snprintf when you don't use the returned value. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
| * | | | [GFS2] Fix cast from unsigned int to s64Andrew Price2008-05-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes bz 444829 where allocating a new block caused gfs2 file systems to report 0 bytes used in df. It was caused by a broken cast from an unsigned int in gfs2_block_alloc() to a negative s64 in gfs2_statfs_change(). This patch casts the unsigned int to an s64 before the unary minus is applied.

| * | | | [GFS2] filesystem consistency error from do_stripBob Peterson2008-05-125-15/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a GFS2 filesystem consistency error reported from function do_strip. The problem was caused by a timing window that allowed two vfs inodes to be created in memory that point to the same file. The problem is fixed by making the vfs's iget_test, iget_set mechanism check and set a new bit in the in-core gfs2_inode structure while the vfs inode spin_lock is held.
