* ext4: Add auto_da_alloc mount optionTheodore Ts'o2009-03-164-15/+17
| | | | | | | | | | | | | Add a mount option which allows the user to disable automatic allocation of blocks whose allocation by delayed allocation when the file was originally truncated or when the file is renamed over an existing file. This feature is intended to save users from the effects of naive application writers, but it reduces the effectiveness of the delayed allocation code. This mount option disables this safety feature, which may be desirable for prodcutions systems where the risk of unclean shutdowns or unexpected system crashes is low.

* ext4: Use struct flex_groups to calculate get_orlov_stats()Theodore Ts'o2009-03-043-17/+31
| | | | | | | | | Instead of looping over all of the block groups in a flex group summing their summary statistics, start tracking used_dirs in struct flex_groups, and use struct flex_groups instead. This should save a bit of CPU for mkdir-heavy workloads. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

* ext4: Fix discard of inode prealloc space with delayed allocation.Aneesh Kumar K.V2009-03-272-2/+10
| | | | | | | | | | | With delayed allocation we should not/cannot discard inode prealloc space during file close. We would still have dirty pages for which we haven't allocated blocks yet. With this fix after each get_blocks request we check whether we have zero reserved blocks and if yes and we don't have any writers on the file we discard inode prealloc space.

* ext4: Automatically allocate delay allocated blocks on renameTheodore Ts'o2009-02-231-1/+4
| | | | | | | | | | | When renaming a file such that a link to another inode is overwritten, force any delay allocated blocks that to be allocated so that if the filesystem is mounted with data=ordered, the data blocks will be pushed out to disk along with the journal commit. Many application programs expect this, so we do this to avoid zero length files if the system crashes unexpectedly. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

* ext4: Save stack space by removing fake buffer headsTheodore Ts'o2009-02-231-44/+39
| | | | | | | | | | | | | | | | Struct mpage_da_data and mpage_add_bh_to_extent() use a fake struct buffer_head which is 104 bytes on an x86_64 system, but only use 24 bytes of the structure. On systems that use a spinlock for atomic_t, the stack savings will be even greater. It turns out that using a fake struct buffer_head doesn't even save that much code, and it makes the code more confusing since it's not used as a "real" buffer head. So just store pass b_size and b_state in mpage_add_bh_to_extent(), and store b_size, b_state, and b_block_nr in the mpage_da_data structure. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

* ext4: return -EIO not -ESTALE on directory traversal through deleted inodeBryan Donlan2009-02-221-2/+10
| | | | | | | | | | | | | | | | | | | | | | | ext4_iget() returns -ESTALE if invoked on a deleted inode, in order to report errors to NFS properly. However, in ext4_lookup(), this -ESTALE can be propagated to userspace if the filesystem is corrupted such that a directory entry references a deleted inode. This leads to a misleading error message - "Stale NFS file handle" - and confusion on the part of the admin. The bug can be easily reproduced by creating a new filesystem, making a link to an unused inode using debugfs, then mounting and attempting to ls -l said link. This patch thus changes ext4_lookup to return -EIO if it receives -ESTALE from ext4_iget(), as ext4 does for other filesystem metadata corruption; and also invokes the appropriate ext*_error functions when this case is detected.

* ext4: New inode/block allocation algorithms for flex_bg filesystemsTheodore Ts'o2009-03-126-58/+216
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The find_group_flex() inode allocator is now only used if the filesystem is mounted using the "oldalloc" mount option. It is replaced with the original Orlov allocator that has been updated for flex_bg filesystems (it should behave the same way if flex_bg is disabled). The inode allocator now functions by taking into account each flex_bg group, instead of each block group, when deciding whether or not it's time to allocate a new directory into a fresh flex_bg. The block allocator has also been changed so that the first block group in each flex_bg is preferred for use for storing directory blocks. This keeps directory blocks close together, which is good for speeding up e2fsck since large directories are more likely to look like this: debugfs: stat /home/tytso/Maildir/cur Inode: 1844562 Type: directory Mode: 0700 Flags: 0x81000 Generation: 1132745781 Version: 0x00000000:0000ad71 User: 15806 Group: 15806 Size: 1060864 File ACL: 0 Directory ACL: 0 Links: 2 Blockcount: 2072 Fragment: Address: 0 Number: 0 Size: 0 ctime: 0x499c0ff4:164961f4 -- Wed Feb 18 08:41:08 2009 atime: 0x499c0ff4:00000000 -- Wed Feb 18 08:41:08 2009 mtime: 0x49957f51:00000000 -- Fri Feb 13 09:10:25 2009 crtime: 0x499c0f57:00d51440 -- Wed Feb 18 08:38:31 2009 Size of extra inode fields: 28 BLOCKS: (0):7348651, (1-258):7348654-7348911 TOTAL: 259 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* ext4: tighten restrictions on inode flagsDuane Griffin2009-02-153-11/+23
| | | | | | | | | | | | | | | | | | At the moment there are few restrictions on which flags may be set on which inodes. Specifically DIRSYNC may only be set on directories and IMMUTABLE and APPEND may not be set on links. Tighten that to disallow TOPDIR being set on non-directories and only NODUMP and NOATIME to be set on non-regular file, non-directories. Introduces a flags masking function which masks flags based on mode and use it during inode creation and when flags are set via the ioctl to facilitate future consistency.

* ext4: allocate ->s_blockgroup_lock separatelyPekka Enberg2009-02-152-3/+11
| | | | | | | | | | | | | | | | | | As spotted by kmemtrace, struct ext4_sb_info is 17664 bytes on 64-bit which makes it a very bad fit for SLAB allocators. The culprit of the wasted memory is ->s_blockgroup_lock which can be as big as 16 KB when NR_CPUS >= 32. To fix that, allocate ->s_blockgroup_lock, which fits nicely in a order 2 page in the worst case, separately. This shinks down struct ext4_sb_info enough to fit a 2 KB slab cache so now we allocate 16 KB + 2 KB instead of 32 KB saving 14 KB of memory.

* ext4: New rec_len encoding for very large blocksizesWei Yongjun2009-02-143-69/+98
| | | | | | | | | | | | | | | | | The rec_len field in the directory entry is 16 bits, so to encode blocksizes larger than 64k becomes problematic. This patch allows us to supprot block sizes up to 256k, by using the low 2 bits to extend the range of rec_len to 2**18-1 (since valid rec_len sizes must be a multiple of 4). We use the convention that a rec_len of 0 or 65535 means the filesystem block size, for compatibility with older kernels. It's unlikely we'll see VM pages of up to 256k, but at some point we might find that the Linux VM has been enhanced to support filesystem block sizes > than the VM page size, at which point it might be useful for some applications to allow very large filesystem block sizes.

* ext4: remove call to ext4_group_desc() in ext4_group_used_meta_blocks()Theodore Ts'o2009-02-061-6/+3
| | | | | | | | | | | | | | | The static function ext4_group_used_meta_blocks() only has one caller, who already has access to the block group's group descriptor. So it's better to have ext4_init_block_bitmap() pass the group descriptor to ext4_group_used_meta_blocks(), so it doesn't need to call ext4_group_desc(). Previously this function did not check if ext4_group_desc() returned NULL due to an error, potentially causing a kernel OOPS report. This avoids the issue entirely.

| | | | | | | | | | | | | | | | | | | | | | | | check_unsafe_exec() also notes whether the fs_struct is being shared by more threads than will get killed by the exec, and if so sets LSM_UNSAFE_SHARE to make bprm_set_creds() careful about euid. But /proc/<pid>/cwd and /proc/<pid>/root lookups make transient use of get_fs_struct(), which also raises that sharing count. This might occasionally cause a setuid program not to change euid, in the same way as happened with files->count (check_unsafe_exec also looks at sighand->count, but /proc doesn't raise that one). We'd prefer exec not to unshare fs_struct: so fix this in procfs, replacing get_fs_struct() by get_fs_path(), which does path_get while still holding task_lock, instead of raising fs->count.

* fix setuid sometimes doesn'tHugh Dickins2009-03-283-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Joe Malicki reports that setuid sometimes doesn't: very rarely, a setuid root program does not get root euid; and, by the way, they have a health check running lsof every few minutes. Right, check_unsafe_exec() notes whether the files_struct is being shared by more threads than will get killed by the exec, and if so sets LSM_UNSAFE_SHARE to make bprm_set_creds() careful about euid. But /proc/<pid>/fd and /proc/<pid>/fdinfo lookups make transient use of get_files_struct(), which also raises that sharing count. There's a rather simple fix for this: exec's check on files->count has been redundant ever since 2.6.1 made it unshare_files() (except while compat_do_execve() omitted to do so) - just remove that check. [Note to -stable: this patch will not apply before 2.6.29: earlier releases should just remove the files->count line from unsafe_exec().] Reported-by: Joe Malicki <jmalicki@metacarta.com> Narrowed-down-by: Michael Itz <mitz@metacarta.com> Tested-by: Joe Malicki <jmalicki@metacarta.com> Signed-off-by: Hugh Dickins <hugh@veritas.com> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* compat_do_execve should unshare_filesHugh Dickins2009-03-281-1/+11
| | | | | | | | | | | | | | | | | | 2.6.26's commit fd8328be874f4190a811c58cd4778ec2c74d2c05 "sanitize handling of shared descriptor tables in failing execve()" moved the unshare_files() from flush_old_exec() and several binfmts to the head of do_execve(); but forgot to make the same change to compat_do_execve(), leaving a CLONE_FILES files_struct shared across exec from a 32-bit process on a 64-bit kernel. It's arguable whether the files_struct really ought to be unshared across exec; but 2.6.1 made that so to stop the loading binary's fd leaking into other threads, and a 32-bit process on a 64-bit kernel ought to behave in the same way as 32 on 32 and 64 on 64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To be on the safe side, it should be less fragile to exclude I_NEW inodes from inode list scans by default (unless there is an important reason to have them). Normally they will get excluded (eg. by zero refcount or writecount etc), however it is a bit fragile for list walkers to know exactly what parts of the inode state is set up and valid to test when in I_NEW.
