=========================================================
[ INFO: possible irq lock inversion dependency detected ]
2.6.24-rc4-git7 #1
---------------------------------------------------------
events/0/9 just changed the state of lock:
(&mc->mca_lock){-+..}, at: [<c0412602>] mld_ifc_timer_expire+0x130/0x1fb
but this lock took another, soft-read-irq-unsafe lock in the past:
(&bond->lock){-.--}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
4 locks held by events/0/9:
#0: (events){--..}, at: [<c0133c8b>] run_workqueue+0x87/0x1b6
#1: ((linkwatch_work).work){--..}, at: [<c0133c8b>] run_workqueue+0x87/0x1b6
#2: (rtnl_mutex){--..}, at: [<c03ac6d4>] linkwatch_event+0x5/0x22
#3: (&ndev->lock){-.-+}, at: [<c04124e9>] mld_ifc_timer_expire+0x17/0x1fb

Yes this is a bug in the bonding driver.
It's assuming that bond->lock is only ever held for writing in
process context. Unfortunately our current set_multicast_list
interface violates this constraint.
Now I do have a TODO item to fix set_multicast_list to not do
that, but until that happens, bond->lock should always turn BH
off, even on read lock.
Cheers,
ping - this regression is apparently still open and unfixed in 2.6.24-rc6. a fix has been suggested by Herbert: the bonding driver should do all bond->lock's as _bh(), to fix this lockup potential. Am i missing something? This bug should be fixed by the following (from netdev-2.6): commit 80ee5ad23150f1f3fe8d35728e860850ccea44da Author: Jay Vosburgh <fubar@us.ibm.com> Date: Tue Jan 29 18:07:44 2008 -0800 bonding: fix set_multicast_list locking This patch eliminates a problem (reported by lockdep) in the bond_set_multicast_list function. It first reduces the locking on bond->lock to a simple read_lock, and second, adds netif_tx locking around the bonding mc_list manipulations that occur outside of the set_multicast_list function.
