It turns out that there are some serious problems with the on-disk format of journal checksum v2. The foremost is that the function to calculate descriptor tag size returns sizes that are too big. This causes alignment issues on some architectures and is compounded by the fact that some parts of jbd2 use the structure size (incorrectly) to determine the presence of a 64bit journal instead of checking the feature flags. Therefore, introduce journal checksum v3, which enlarges the descriptor block tag format to allow for full 32-bit checksums of journal blocks, fix the journal tag function to return the correct sizes, and fix the jbd2 recovery code to use feature flags to determine 64bitness. Add a few function helpers so we don't have to open-code quite so many pieces. Switching to a 16-byte block size was found to increase journal size overhead by a maximum of 0.1%, to convert a 32-bit journal with no checksumming to a 32-bit journal with checksum v3 enabled.

When recovering the journal, don't fall into an infinite loop if we encounter a corrupt journal block. Instead, just skip the block and return an error, which fails the mount and thus forces the user to run a full filesystem fsck. Signed-off-by: NDarrick J.

In case of delalloc block i_disksize may be less than i_size. So we have to update i_disksize each time we allocated and submitted some blocks beyond i_disksize. We weren't doing this on the error paths, so fix this. testcase: xfstest generic/019 Signed-off-by: NDmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: NTheodore Ts'o <tytso@mit.edu> Cc: stable@vger.kernel.org

After commit f282ac19 we use different transactions for preallocation and i_disksize update which result in complain from fsck after power-failure. spotted by generic/019. IMHO this is regression because fs becomes inconsistent, even more 'e2fsck -p' will no longer works (which drives admins go crazy) Same transaction requirement applies ctime,mtime updates testcase: xfstest generic/019 Signed-off-by: NDmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: NTheodore Ts'o <tytso@mit.edu> Cc: stable@vger.kernel.org

If we suffer a block allocation failure (for example due to a memory allocation failure), it's possible that we will call ext4_discard_allocated_blocks() before we've actually allocated any blocks. In that case, fe_len and fe_start in ac->ac_f_ex will still be zero, and this will result in mb_free_blocks(inode, e4b, 0, 0) triggering the BUG_ON on mb_free_blocks(): BUG_ON(last >= (sb->s_blocksize << 3)); Fix this by bailing out of ext4_discard_allocated_blocks() if fs_len is zero. Also fix a missing ext4_mb_unload_buddy() call in ext4_discard_allocated_blocks(). Google-Bug-Id: 16844242 Fixes: 86f0afd4Signed-off-by: NTheodore Ts'o <tytso@mit.edu> Cc: stable@vger.kernel.org

If we run into some kind of error, such as ENOMEM, while calling ext4_getblk() or ext4_dx_find_entry(), we need to make sure this error gets propagated up to ext4_find_entry() and then to its callers. This way, transient errors such as ENOMEM can get propagated to the VFS. This is important so that the system calls return the appropriate error, and also so that in the case of ext4_lookup(), we return an error instead of a NULL inode, since that will result in a negative dentry cache entry that will stick around long past the OOM condition which caused a transient ENOMEM error.

Some Toshiba models (most notably Qosmios) come with an incomplete backlight method where the AML code doesn't check for write or read commands and always returns HCI_SUCCESS and the actual brightness (and in some cases the max brightness), thus allowing the backlight interface to be registered without write support.
