* ext2: No longer export ext2_fs.h to user spaceThierry Reding2012-03-311-62/+10
| | | | | | | | | | | | | | | | | | | Since the on-disk format has been stable for quite some time, users should either use the headers provided by libext2fs or keep a private copy of this header. For the full discussion, see this thread: https://lkml.org/lkml/2012/3/21/516 While at it, this commit removes all __KERNEL__ guards, which are now unnecessary.

* ext2,ext3,ext4: don't inherit APPEND_FL or IMMUTABLE_FL for new inodesTheodore Ts'o2011-08-311-2/+2
| | | | | | | | | | | This doesn't make much sense, and it exposes a bug in the kernel where attempts to create a new file in an append-only directory using O_CREAT will fail (but still leave a zero-length file). This was discovered when xfstests #79 was generalized so it could run on all file systems. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc:stable@kernel.org

* ext2: Explicitly assign values to on-disk enum of filetypesJan Blunck2009-12-101-8/+8
| | | | | | | | | It is somewhat dangerous to use a straight enum here, because this will reassign values of later variables if one of the earlier ones is removed. Signed-off-by: Jan Blunck <jblunck@suse.de> Cc: Andreas Dilger <adilger@sun.com> Signed-off-by: Jan Kara <jack@suse.cz>
* ext2: tighten restrictions on inode flagsDuane Griffin2009-01-081-0/+17
| | | | | | | | | | | | | | | | | | 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.

* ext2: don't inherit inappropriate inode flags from parentDuane Griffin2009-01-081-0/+7
| | | | | | | | | | | | | | | | At present BTREE/INDEX is the only flag that new ext2 inodes do NOT inherit from their parent. In addition prevent the flags DIRTY, ECOMPR, INDEX, IMAGIC and TOPDIR from being inherited. List inheritable flags explicitly to prevent future flags from accidentally being inherited. This fixes the TOPDIR flag inheritance bug reported at http://bugzilla.kernel.org/show_bug.cgi?id=9866.

| | | | | | | | | | | | With 64KB blocksize, a directory entry can have size 64KB which does not fit into 16 bits we have for entry length.

* [PATCH] disk quotas fail when /etc/mtab is symlinked to /proc/mountsMark Bellon2005-09-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If /etc/mtab is a regular file all of the mount options (of a file system) are written to /etc/mtab by the mount command. The quota tools look there for the quota strings for their operation. If, however, /etc/mtab is a symlink to /proc/mounts (a "good thing" in some environments) the tools don't write anything - they assume the kernel will take care of things. While the quota options are sent down to the kernel via the mount system call and the file system codes handle them properly unfortunately there is no code to echo the quota strings into /proc/mounts and the quota tools fail in the symlink case. The attached patchs modify the EXT[2|3] and JFS codes to add the necessary hooks. The show_options function of each file system in these patches currently deal with only those things that seemed related to quotas; especially in the EXT3 case more can be done (later?). Jan Kara also noted the difficulty in moving these changes above the FS codes responding similarly to myself to Andrew's comment about possible VFS migration. Issue summary: - FS codes have to process the entire string of options anyway. - Only FS codes that use quotas must have a show_options function (for quotas to work properly) however quotas are only used in a small number of FS. - Since most of the quota using FS support other options these FS codes should have the a show_options function to show those options - and the quota echoing becomes virtually negligible. Based on feedback I have modified my patches from the original: JFS a missing patch has been restored to the posting EXT[2|3] and JFS always use the show_options function - Each FS has at least one FS specific option displayed - QUOTA output is under a CONFIG_QUOTA ifdef - a follow-on patch will add a multitude of options for each FS EXT[2|3] and JFS "quota" is treated as "usrquota" EXT3 journalled data check for journalled quota removed EXT[2|3] mount when quota specified but not compiled in - no changes from my original patch. I tested the patch and the codes warn but - still mount. With all due respection I believe the comments otherwise were a - misread of the patch. Please reread/test and comment. XFS patch removed - the XFS team already made the necessary changes EXT3 mixing old and new quotas are handled differently (not purely exclusive) - if old and new quotas for the same type are used together the old type is silently depricated for compatability (e.g. usrquota and usrjquota) - mixing of old and new quotas is an error (e.g. usrjquota and grpquota) Signed-off-by: Mark Bellon <mbellon@mvista.com> Acked-by: Dave Kleikamp <shaggy@austin.ibm.com> Cc: Jan Kara <jack@ucw.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+553
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
