| * move file time and dos attribute setting logic into new functionJeff Layton2008-08-06
| | | | | | | | | | | | | | | | | | | | | | Break up cifs_setattr further by moving the logic that sets file times and dos attributes into a separate function. This patch also refactors the logic a bit so that when the file is already open then we go ahead and do a SetFileInfo call. SetPathInfo seems to be unreliable when setting times on open files.

| * [CIFS] cifs_mkdir and cifs_create should respect the setgid bit on parent dirJeff Layton2008-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a server supports unix extensions but does not support POSIX create routines, then the client will create a new inode with a standard SMB mkdir or create/open call and then will set the mode. When it does this, it does not take the setgid bit on the parent directory into account. This patch has CIFS flip on the setgid bit when the parent directory has it. If the share is mounted with "setuids" then also change the group owner to the gid of the parent. This patch should apply cleanly on top of the setattr cleanup patches that I sent a few weeks ago.

| * | ext4: Fix lack of credits BUG() when deleting a badly fragmented inodeTheodore Ts'o2008-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The extents codepath for ext4_truncate() requests journal transaction credits in very small chunks, requesting only what is needed. This means there may not be enough credits left on the transaction handle after ext4_truncate() returns and then when ext4_delete_inode() tries finish up its work, it may not have enough transaction credits, causing a BUG() oops in the jbd2 core. Also, reserve an extra 2 blocks when starting an ext4_delete_inode() since we need to update the inode bitmap, as well as update the orphaned inode linked list.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ext4_ext_journal_restart() is a convenience function which checks to see if the requested number of credits is present, and if so it closes the current transaction and attaches the current handle to the new transaction. Unfortunately, it wasn't proprely checking the return value from ext4_journal_extend(), so it was starting a new transaction when one was not necessary, and returning an error when all that was necessary was to restart the handle with a new transaction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ordered mode, the current jbd2 aborts the journal if a file data buffer has an error. But this behavior is unintended, and we found that it has been adopted accidentally. This patch undoes it and just calls printk() instead of aborting the journal. Unlike a similar patch for ext3/jbd, file data buffers are written via generic_writepages(). But we also need to set AS_EIO into their mappings because wait_on_page_writeback_range() clears AS_EIO before a user process sees it.

| * | ext4: don't read inode block if the buffer has a write errorHidehiro Kawai2008-07-26

Here is the scenario: (1) update inode_A at the block_B (2) pdflush writes out new inode_A to the filesystem, but it results in write I/O error, at this point, BH_Uptodate flag of the buffer for block_B is cleared and BH_Write_EIO is set (3) create new inode_C which located at block_B, and __ext4_get_inode_loc() tries to read on-disk block_B because the buffer is not uptodate (4) if it can read on-disk block_B successfully, inode_A is overwritten by old data This patch makes __ext4_get_inode_loc() not read the inode block if the buffer has BH_Write_EIO flag. In this case, the buffer should have the latest information, so setting the uptodate flag to the buffer (this avoids WARN_ON_ONCE() in mark_buffer_dirty().) According to this change, we would need to test BH_Write_EIO flag for the error checking. Currently nobody checks write I/O errors on metadata buffers, but it will be done in other patches I'm working on.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the locality group prealloc list is freed only when there is a block allocation failure. This can result in large number of entries in the preallocation list making ext4_mb_use_preallocated() expensive. To fix this, we convert the locality group prealloc list to a hash list. The hash index is the order of number of blocks in the prealloc space with a max order of 9. When adding prealloc space to the list we make sure total entries for each order does not exceed 8. If it is more than 8 we discard few entries and make sure the we have only <= 5 entries. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inserting an extent can cause a new entry in the already existing index block. That doesn't increase the depth of the instead. Instead it adds a new leaf block. Now with the new leaf block the path information corresponding to the logical block should be fetched from the new block. The old path will be pointing to the old leaf block. We need to recalucate the path information on extent insert even if depth doesn't change. Without this change, the extent merge after converting an unwritten extent to initialized extent takes the wrong extent and cause data corruption.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These days most of the attributes in struct inode are properly kept in sync by XFS. This patch removes the need for vn_revalidate completely by: - keeping inode.i_flags uptodate after any flags are updated in xfs_ioctl_setattr - keeping i_mode, i_uid and i_gid uptodate in xfs_setattr SGI-PV: 984566 SGI-Modid: xfs-linux-melb:xfs-kern:31679a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Tim Shimmin <tes@sgi.com> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>

Also rename the ATTR_ flags to XFS_ATTR_ to not conflict with the ATTR_ flags used by the VFS.

Having these in a single function makes it more complicated and forces to have us a bhv_vattr intermediate structure eating up stackspace. This patch adds a new xfs_ioctl_setattr helper for the XFS ioctls that set these attributes and remove the code to set them through xfs_setattr.
