2012-11-29fs/buffer.c: make block-size be per-page and protected by the page lockLinus Torvalds1-31/+48
This makes the buffer size handling be a per-page thing, which allows us to not have to worry about locking too much when changing the buffer size. If a page doesn't have buffers, we still need to read the block size from the inode, but we can do that with ACCESS_ONCE(), so that even if the size is changing, we get a consistent value. This doesn't convert all functions - many of the buffer functions are used purely by filesystems, which in turn results in the buffer size being fixed at mount-time. So they don't have the same consistency issues that the raw device access can have. Signed-off-by: Linus Torvalds <[email protected]>
2012-11-29bonding: fix race condition in bonding_store_slaves_active[email protected]1-0/+2
Race between bonding_store_slaves_active() and slave manipulation functions. The bond_for_each_slave use in bonding_store_slaves_active() is not protected by any synchronization mechanism. NULL pointer dereference is easy to reach. Fixed by acquiring the bond->lock for the slave walk. v2: Make description text < 75 columns Signed-off-by: Nikolay Aleksandrov <[email protected]> Signed-off-by: Jay Vosburgh <[email protected]> Signed-off-by: David S.

The module can be loaded with arp_ip_target="255.255.255.255" which makes it impossible to remove as the function in sysfs checks for that value, so we make the parameter checks consistent with sysfs. v2: Fix formatting v3: Make description text < 75 columns Signed-off-by: Nikolay Aleksandrov <[email protected]> Signed-off-by: Jay Vosburgh <[email protected]> Signed-off-by: David S.

2012-11-29bonding: fix miimon and arp_interval delayed work race conditions[email protected]2-86/+36
First I would give three observations which will be used later. Observation 1: if (delayed_work_pending(wq)) cancel_delayed_work(wq) This usage is wrong because the pending bit is cleared just before the work's fn is executed and if the function re-arms itself we might end up with the work still running. It's safe to call cancel_delayed_work_sync() even if the work is not queued at all. Observation 2: Use of INIT_DELAYED_WORK() Work needs to be initialized only once prior to (de/en)queueing. Observation 3: IFF_UP is set only after ndo_open is called Related race conditions: 1. Race between bonding_store_miimon() and bonding_store_arp_interval() Because of Obs.1 we can end up having both works enqueued. 2. Multiple races with INIT_DELAYED_WORK() Since the works are not protected by anything between INIT_DELAYED_WORK() and calls to (en/de)queue it is possible for races between the following functions: (races are also possible between the calls to INIT_DELAYED_WORK() and workqueue code) bonding_store_miimon() - bonding_store_arp_interval(), bond_close(), bond_open(), enqueued functions bonding_store_arp_interval() - bonding_store_miimon(), bond_close(), bond_open(), enqueued functions 3. By Obs.1 we need to change bond_cancel_all() Bugs 1 and 2 are fixed by moving all work initializations in bond_open which by Obs. 2 and Obs. 3 and the fact that we make sure that all works are cancelled in bond_close(), is guaranteed not to have any work enqueued. Also RTNL lock is now acquired in bonding_store_miimon/arp_interval so they can't race with bond_close and bond_open. The opposing work is cancelled only if the IFF_UP flag is set and it is cancelled unconditionally. The opposing work is already cancelled if the interface is down so no need to cancel it again. This way we don't need new synchronizations for the bonding workqueue. These bugs (and fixes) are tied together and belong in the same patch. Note: I have left 1 line intentionally over 80 characters (84) because I didn't like how it looks broken down. If you'd prefer it otherwise, then simply break it. v2: Make description text < 75 columns Signed-off-by: Nikolay Aleksandrov <[email protected]> Signed-off-by: Jay Vosburgh <[email protected]> Signed-off-by: David S.

2012-11-28ARM: 7586/1: sp804: set cpumask to cpu_possible_mask for clock event deviceWill Deacon1-1/+1
The SP804 driver statically initialises the cpumask of the clock event device to be cpu_all_mask, which is derived from the compile-time constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt controller handling the sp804 doesn't have the irq_set_affinity callback on the irq_chip, because the common timer code fails to identify the device as cpu-local and ends up treating it as a broadcast device instead. This patch fixes the problem by using cpu_possible_mask at runtime, which will correctly represent the possible CPUs when SMP_ON_UP is being used.
