| * ext3: fix start and len arguments handling in ext3_trim_fs()Lukas Czerner2012-03-021-38/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The overflow might happen when passing blocknr into ext3_get_group_no_and_offset(), because it expects type ext3_fsblk_t which might be smaller than uint64_t. This will most likely happen when calling FITRIM with the default argument len = ULLONG_MAX. Fix this by using "end" variable instead of "start+len" as it is easier to get right and specifically check that the end is not beyond the end of the file system, so we are sure that the result of get_group_no_and_offset() will not overflow. Otherwise truncate it to the size of the file system. Signed-off-by: Lukas Czerner <lczerner@redhat.com> Cc: Jan Kara <jack@suse.cz> Signed-off-by: Jan Kara <jack@suse.cz>
| * ext3: Update ctime in ext3_splice_branch() only when neededKazuya Mio2012-02-291-3/+6
| | | | | | | | | | | | | | | | | | Currently ext3 updates ctime in ext3_splice_branch() which is called whenever we allocate one block. But it is wasteful because ext3 doesn't support nanosecond timestamp. This leads to a performance loss. Signed-off-by: Kazuya Mio <k-mio@sx.jp.nec.com> Signed-off-by: Jan Kara <jack@suse.cz>

| | | | | | | | | | | | | | | | | | | | dquot_free_block() is called in the end of ext3_new_blocks() and updates information of the inode structure. However, this update is not necessary if the number of blocks we requested is equal to the number of allocated blocks.

| | | | | | | | | | | | | | | | | | | | | | Delete any instances of include module.h that were not strictly required. In the case of ext2, the declaration of MODULE_LICENSE etc. were in inode.c but the module_init/exit were in super.c, so relocate the MODULE_LICENCE/AUTHOR block to super.c which makes it consistent with ext3 and ext4 at the same time.

| * ext{3,4}: Fix potential race when setversion ioctl updates inodeDjalal Harouni2012-01-091-1/+5
| | | | | | | | | | | | | | | | | | | | | | The EXT{3,4}_IOC_SETVERSION ioctl() updates i_ctime and i_generation without i_mutex. This can lead to a race with the other operations that update i_ctime. This is not a big issue but let's make the ioctl consistent with how we handle e.g. other timestamp updates and use i_mutex to protect inode changes.

| * ext3: Don't warn from writepage when readonly inode is spotted after errorJan Kara2012-01-091-3/+21
| | | | | | | | | | | | | | | | | | | | | | | | WARN_ON_ONCE(IS_RDONLY(inode)) tends to trip when filesystem hits error and is remounted read-only. This unnecessarily scares users (well, they should be scared because of filesystem error, but the stack trace distracts them from the right source of their fear ;-). We could as well just remove the WARN_ON but it's not hard to fix it to not trip on filesystem with errors and not use more cycles in the common case so that's what we do.

| * ext3: Fix error handling on inode bitmap corruptionJan Kara2012-01-091-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | When insert_inode_locked() fails in ext3_new_inode() it most likely means inode bitmap got corrupted and we allocated again inode which is already in use. Also doing unlock_new_inode() during error recovery is wrong since inode does not have I_NEW set. Fix the problem by jumping to fail: (instead of fail_drop:) which declares filesystem error and does not call unlock_new_inode().

* | ext[34]: avoid i_nlink warnings triggered by drop_nlink/inc_nlink kludge in ↵Al Viro2012-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | symlink() Both ext3 and ext4 put the half-created symlink inode into the orphan list for a while (see the comment in ext[34]_symlink() for gory details). Then, if everything went fine, they pull it out of the orphan list and bump the link count back to 1. The thing is, inc_nlink() is going to complain about seeing somebody changing i_nlink from 0 to 1. With a good reason, since normally something like that is a bug. Explicit set_nlink(inode, 1) does the same thing as inc_nlink() here, but it does *not* complain - exactly because it should be usable in strange situations like this one.

| | * | security: new security_inode_init_security API adds function callbackMimi Zohar2011-07-181-16/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the security_inode_init_security API by adding a filesystem specific callback to write security extended attributes. This change is in preparation for supporting the initialization of multiple LSM xattrs and the EVM xattr. Initially the callback function walks an array of xattrs, writing each xattr separately, but could be optimized to write multiple xattrs at once. For existing security_inode_init_security() calls, which have not yet been converted to use the new callback function, such as those in reiserfs and ocfs2, this patch defines security_old_inode_init_security().

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ae54870a1dc9 ("ext3: Fix lock inversion in ext3_symlink()") recalculated the number of credits needed for a long symlink, in the process of splitting it into two transactions. However, the first credit calculation under-counted because if selinux is enabled, credits are needed to create the selinux xattr as well. Overrunning the reservation will result in an OOPS in journal_dirty_metadata() due to this assert: J_ASSERT_JH(jh, handle->h_buffer_credits > 0); Fix this by increasing the reservation size.

| * | ext3: Fix data corruption in inodes with journalled dataJan Kara2011-07-231-5/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When journalling data for an inode (either because it is a symlink or because the filesystem is mounted in data=journal mode), ext3_evict_inode() can discard unwritten data by calling truncate_inode_pages(). This is because we don't mark the buffer / page dirty when journalling data but only add the buffer to the running transaction and thus mm does not know there are still unwritten data. Fix the problem by carefully tracking transaction containing inode's data, committing this transaction, and writing uncheckpointed buffers when inode should be reaped.
