2010-10-28quota: Fix issuing of warnings from dquot_transferJan Kara
__dquot_transfer accidentally called flush_warnings for a wrong set of dquots which could result in quota warnings being issued with a wrong identification. Also when operation fails because of EDQUOT, there's no need check for issuing information message about user getting below limits (no transfer has actually happened).

2010-10-28quota: fix dquot_disable vs dquot_transfer race v2Dmitry
I've got following lockup: dquot_disable dquot_transfer ->dqget() sb_has_quota_active dqopt->flags &= ~dquot_state_flag(f, cnt) atomic_inc(dq->dq_count) ->drop_dquot_ref(sb, cnt); down_write(dqptr_sem) inode->i_dquot[cnt] = NULL ->__dquot_transfer invalidate_dquots(sb, cnt); down_write(&dqptr_sem) ->wait for dq_wait_unused inode->i_dquot = new_dquot /* wait forever */ ^^^^New quota user^^^^^^ We cannot allow new references to dquots from inodes after drop_dquot_ref() has removed them. We have to recheck quota state under dqptr_sem and before assignment, as we do it in dquot_initialize(). Signed-off-by: Dmitry Monakhov <dmonakhov@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>

2010-10-28ext3/jbd: Avoid WARN() messages when failing to write the superblockDarrick J. Wong
This fixes a WARN backtrace in mark_buffer_dirty() that occurs during unmount when the underlying block device is removed. This bug has been seen on System Z when removing all paths from a multipath-backed ext3 mount; on System P when injecting enough PCI EEH errors to make the SCSI controller go offline; and similar warnings have been seen (and patched) with ext2/ext4. The super block update from a previous operation has marked the buffer as in error, and the flag has to be cleared before doing the update. Similar changes have been made to ext4 by commit 914258bf2cb22bf4336a1b1d90c551b4b11ca5aa. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: Jan Kara <jack@suse.cz>

2010-10-27tunnels: Fix tunnels change rcu protectionPavel Emelyanov
After making rcu protection for tunnels (ipip, gre, sit and ip6) a bug was introduced into the SIOCCHGTUNNEL code. The tunnel is first unlinked, then addresses change, then it is linked back probably into another bucket. But while changing the parms, the hash table is unlocked to readers and they can lookup the improper tunnel. Respective commits are b7285b79 (ipip: get rid of ipip_lock), 1507850b (gre: get rid of ipgre_lock), 3a43be3c (sit: get rid of ipip6_lock) and 94767632 (ip6tnl: get rid of ip6_tnl_lock). The quick fix is to wait for quiescent state to pass after unlinking, but if it is inappropriate I can invent something better, just let me know.

2010-10-27fasync: re-organize fasync entry insertion to allow it under a spinlockLinus Torvalds
You currently cannot use "fasync_helper()" in an atomic environment to insert a new fasync entry, because it will need to allocate the new "struct fasync_struct". Yet fcntl_setlease() wants to call this under lock_flocks(), which is in the process of being converted from the BKL to a spinlock. In order to fix this, this abstracts out the actual fasync list insertion and the fasync allocations into functions of their own, and teaches fs/locks.c to pre-allocate the fasync_struct entry. That way the actual list insertion can happen while holding the required spinlock.

2010-10-27ath9k: add locking for stopping RXLuis R. Rodriguez
ath9k locks for starting RX but not for stopping RX. We could potentially run into a situation where tried to stop RX but immediately started RX. This allows for races on the the RX engine deciding what buffer we last left off on and could potentially cause ath9k to DMA into already free'd memory or in the worst case at a later time to already given memory to other drivers. Fix this by locking stopping RX. This is part of a series that will help resolve the bug: https://bugzilla.kernel.org/show_bug.cgi?id=14624 For more details about this issue refer to: http://marc.info/?l=linux-wireless&m=128629803703756&w=2 Cc: stable@kernel.org Cc: Ben Greear <greearb@candelatech.com> Cc: Kyungwan Nam <kyungwan.nam@atheros.com> Signed-off-by: Luis R.

2010-10-27lockd: push lock_flocks downArnd Bergmann
lockd should use lock_flocks() instead of lock_kernel() to lock against posix locks accessing the i_flock list. This is a prerequisite to turning lock_flocks into a spinlock. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: J. Bruce Fields <bfields@redhat.com>
