ext2: protect inode changes in the SETVERSION and SETFLAGS ioctls

2012-01-11T12:39:02Z

Unlock mutex after i_flags and i_ctime updates in the EXT2_IOC_SETFLAGS ioctl. Use i_mutex in the EXT2_IOC_SETVERSION ioctl to protect i_ctime and i_generation updates and make the ioctl consistent since i_mutex is also used in other places to protect timestamps and inode changes.

vfs: mnt_drop_write_file()

2012-01-04T03:52:40Z

new helper (wrapper around mnt_drop_write()) to be used in pair with mnt_want_write_file(). Signed-off-by: Al Viro

switch a bunch of places to mnt_want_write_file()

2012-01-04T03:52:35Z

it's both faster (in case when file has been opened for write) and cleaner. Signed-off-by: Al Viro

headers: smp_lock.h redux

2009-07-12T19:22:34Z

* Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan Signed-off-by: Linus Torvalds

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.

[PATCH] r/o bind mounts: elevate write count for ioctls()

2008-04-19T04:29:24Z

Some ioctl()s can cause writes to the filesystem. Take these, and make them use mnt_want/drop_write() instead. [AV: updated] Acked-by: Al Viro Signed-off-by: Christoph Hellwig Signed-off-by: Dave Hansen Signed-off-by: Andrew Morton Signed-off-by: Al Viro

BKL-removal: convert ext2 over to use unlocked_ioctl

2008-02-06T18:41:20Z

I checked ext2_ioctl and could not find anything in there that would need the BKL. So convert it over to use unlocked_ioctl Signed-off-by: Andi Kleen Cc: Theodore Ts'o Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Forbid user to change file flags on quota files

2007-11-15T02:45:38Z

Forbid user from changing file flags on quota files. User has no bussiness in playing with these flags when quota is on. Furthermore there is a remote possibility of deadlock due to a lock inversion between quota file's i_mutex and transaction's start (i_mutex for quota file is locked only when trasaction is started in quota operations) in ext3 and ext4.
