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.

nfsd race fixes: ext2

2008-12-31T23:07:43Z

* make ext2_new_inode() put the inode into icache in locked state * do not unlock until the inode is fully set up; otherwise nfsd might pick it in half-baked state. * make sure that ext2_new_inode() does *not* lead to two inodes with the same inumber hashed at the same time; otherwise a bogus fhandle coming from nfsd might race with inode creation: nfsd: iget_locked() creates inode nfsd: try to read from disk, block on that. ext2_new_inode(): allocate inode with that inumber ext2_new_inode(): insert it into icache, set it up and dirty ext2_write_inode(): get the relevant part of inode table in cache, set the entry for our inode (and start writing to disk) nfsd: get CPU again, look into inode table, see nice and sane on-disk inode, set the in-core inode from it oops - we have two in-core inodes with the same inumber live in icache, both used for IO.

CRED: Wrap task credential accesses in the Ext2 filesystem

2008-11-13T23:38:50Z

Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

remove unused bh in calls to ext234_get_group_desc

2007-10-17T15:42:49Z

ext[234]_get_group_desc never tests the bh argument, and only sets it if it is passed in; it is perfectly happy with a NULL bh argument. But, many callers send one in and never use it. May as well call with NULL like other callers who don't use the bh. Signed-off-by: Eric Sandeen Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
