| * reiserfs: Fix use after free in journal teardownJan Kara2014-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If do_journal_release() races with do_journal_end() which requeues delayed works for transaction flushing, we can leave work items for flushing outstanding transactions queued while freeing them. That results in use after free and possible crash in run_timers_softirq(). Fix the problem by not requeueing works if superblock is being shut down (MS_ACTIVE not set) and using cancel_delayed_work_sync() in do_journal_release().

| * reiserfs: fix corruption introduced by balance_leaf refactorJeff Mahoney2014-08-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commits f1f007c308e (reiserfs: balance_leaf refactor, pull out balance_leaf_insert_left) and cf22df182bf (reiserfs: balance_leaf refactor, pull out balance_leaf_paste_left) missed that the `body' pointer was getting repositioned. Subsequent users of the pointer would expect it to be repositioned, and as a result, parts of the tree would get overwritten. The most common observed corruption is indirect block pointers being overwritten. Since the body value isn't actually used anymore in the called routines, we can pass back the offset it should be shifted. We constify the body and ih pointers in the balance_leaf as a mostly-free preventative measure.

| * | reiserfs: call truncate_setsize under tailpack mutexJeff Mahoney2014-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to commit 0e4f6a791b1e (Fix reiserfs_file_release()), reiserfs truncates serialized on i_mutex. They mostly still do, with the exception of reiserfs_file_release. That blocks out other writers via the tailpack mutex and the inode openers counter adjusted in reiserfs_file_open. However, NFS will call reiserfs_setattr without having called ->open, so we end up with a race when nfs is calling ->setattr while another process is releasing the file. Ultimately, it triggers the BUG_ON(inode->i_size != new_file_size) check in maybe_indirect_to_direct. The solution is to pull the lock into reiserfs_setattr to encompass the truncate_setsize call as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | jdm-20004 reiserfs_delete_xattrs: Couldn't delete all xattrs (-2) The -ENOENT is due to readdir calling dir_emit on the same entry twice. If the dir_emit callback sleeps and the tree is changed underneath us, we won't be able to trust deh_offset(deh) anymore. We need to save next_pos before we might sleep so we can find the next entry.
