2012-07-23Merge tag 'upstream-3.6-rc1' of git://git.infradead.org/linux-ubifsLinus Torvalds1-1/+1
Pull UBIFS updates from Artem Bityutskiy: - Added another debugfs knob for forcing UBIFS R/O mode without flushing caches or finishing commit or any other I/O operation. I've originally added this knob in order to reproduce the free space fixup bug (see commit c6727932cfdb: "UBIFS: fix a bug in empty space fix-up") on nandsim. Without this knob I would have to do real power-cuts, which would make debugging much harder. Then I've decided to keep this knob because it is also useful for UBIFS power-cut recovery end error-paths testing. - Well-spotted fix from Julia. This bug did not cause real troubles for UBIFS, but nevertheless it could cause issues for someone trying to modify the orphans handling code. Kudos to coccinelle! - Minor cleanups. * tag 'upstream-3.6-rc1' of git://git.infradead.org/linux-ubifs: UBIFS: remove invalid reference to list iterator variable UBIFS: simplify reply code a bit UBIFS: add debugfs knob to switch to R/O mode UBIFS: fix compilation warning

2012-02-29UBIFS: do not use inc_link when i_nlink is zeroArtem Bityutskiy1-9/+9
This patch changes the 'i_nlink' counter handling in 'ubifs_unlink()', 'ubifs_rmdir()' and 'ubifs_rename()'. In these function 'i_nlink' may become 0, and if 'ubifs_jnl_update()' failed, we would use 'inc_nlink()' to restore the previous 'i_nlink' value, which is incorrect from the VFS point of view and would cause a 'WARN_ON()' (see 'inc_nlink() implementation). This patches saves the previous 'i_nlink' value in a local variable and uses it at the error path instead of calling 'inc_nlink()'. We do this only for the inodes where 'i_nlink' may potentially become zero. This change has been requested by Al Viro <viro@ZenIV.linux.org.uk>.

2011-07-04UBIFS: introduce helper functions for debugging checks and testsArtem Bityutskiy1-1/+1
This patch introduces helper functions for all debugging checks, so instead of doing if (!(ubifs_chk_flags & UBIFS_CHK_GEN)) we now do if (!dbg_is_chk_gen(c)) This is a preparation to further changes where the flags will go away, and we'll need to only change the helper functions, but the code which utilizes them won't be touched. At the same time this patch removes 'dbg_force_in_the_gaps()', 'dbg_force_in_the_gaps_enabled()', and dbg_failure_mode helpers for consistency.

This patch separates out all the budgeting-related information from 'struct ubifs_info' to 'struct ubifs_budg_info'. This way the code looks a bit cleaner. However, the main driver for this is that we want to save budgeting information and print it later, so a separate data structure for this is helpful.

2009-05-19UBIFS: return error if link and unlink raceHunter Adrian1-0/+19
Consider a scenario when 'vfs_link(dirA/fileA)' and 'vfs_unlink(dirA/fileA, dirB/fileB)' race. 'vfs_link()' does not lock 'dirA->i_mutex', so this is possible. Both of the functions lock 'fileA->i_mutex' though. Suppose 'vfs_unlink()' wins, and takes 'fileA->i_mutex' mutex first. Suppose 'fileA->i_nlink' is 1. In this case 'ubifs_unlink()' will drop the last reference, and put 'inodeA' to the list of orphans. After this, 'vfs_link()' will link 'dirB/fileB' to 'inodeA'. Thir is a problem because, for example, the subsequent 'vfs_unlink(dirB/fileB)' will add the same inode to the list of orphans. This problem was reported by J. R.

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().
