fs/vfs/security: pass last path component to LSM on inode creation

2011-02-01T16:12:29Z

SELinux would like to implement a new labeling behavior of newly created inodes. We currently label new inodes based on the parent and the creating process. This new behavior would also take into account the name of the new object when deciding the new label. This is not the (supposed) full path, just the last component of the path. This is very useful because creating /etc/shadow is different than creating /etc/passwd but the kernel hooks are unable to differentiate these operations. We currently require that userspace realize it is doing some difficult operation like that and than userspace jumps through SELinux hoops to get things set up correctly. This patch does not implement new behavior, that is obviously contained in a seperate SELinux patch, but it does pass the needed name down to the correct LSM hook. If no such name exists it is fine to pass NULL. Signed-off-by: Eric Paris

ext2: remove useless call to brelse() in ext2_free_inode()

2010-05-21T17:30:37Z

This patch removes a useless call to brelse(bitmap_bh) since at that point bitmap_bh is NULL and slightly cleans up bitmap_bh handling. Signed-off-by: Francis Moreau Signed-off-by: Jan Kara

dquot: cleanup dquot initialize routine

2010-03-04T23:20:30Z

Get rid of the initialize dquot operation - it is now always called from the filesystem and if a filesystem really needs it's own (which none currently does) it can just call into it's own routine directly. Rename the now static low-level dquot_initialize helper to __dquot_initialize and vfs_dq_init to dquot_initialize to have a consistent namespace.

dquot: cleanup dquot drop routine

2010-03-04T23:20:30Z

Get rid of the drop dquot operation - it is now always called from the filesystem and if a filesystem really needs it's own (which none currently does) it can just call into it's own routine directly. Rename the now static low-level dquot_drop helper to __dquot_drop and vfs_dq_drop to dquot_drop to have a consistent namespace. Signed-off-by: Christoph Hellwig Signed-off-by: Jan Kara

dquot: cleanup inode allocation / freeing routines

2010-03-04T23:20:28Z

Get rid of the alloc_inode and free_inode dquot operations - they are always called from the filesystem and if a filesystem really needs their own (which none currently does) it can just call into it's own routine directly. Also get rid of the vfs_dq_alloc/vfs_dq_free wrappers and always call the lowlevel dquot_alloc_inode / dqout_free_inode routines directly, which now lose the number argument which is always 1.

ext2: tighten restrictions on inode flags

2009-01-08T16:31:00Z

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 parent

2009-01-08T16:31:00Z

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.
