bonding: fix bond_get_stats()

2016-07-11T03:07:05Z

[ Upstream commit fe30937b65354c7fec244caebbdaae68e28ca797 ] bond_get_stats() can be called from rtnetlink (with RTNL held) or from /proc/net/dev seq handler (with RCU held) The logic added in commit 5f0c5f73e5ef ("bonding: make global bonding stats more reliable") kind of assumed only one cpu could run there. If multiple threads are reading /proc/net/dev, stats can be really messed up after a while. A second problem is that some fields are 32bit, so we need to properly handle the wrap around problem. Given that RTNL is not always held, we need to use bond_for_each_slave_rcu().

net/bonding: Make DRV macros private

2015-04-27T02:59:53Z

The bonding modules currently defines four macros with general names that pollute the global namespace: DRV_VERSION DRV_RELDATE DRV_NAME DRV_DESCRIPTION Fixing that by defining a private bonding_priv.h header files which includes those defines.

net/bonding: Fix potential bad memory access during bonding events

2015-02-09T22:03:53Z

When queuing work to send the NETDEV_BONDING_INFO netdev event, it's possible that when the work is executed, the pointer to the slave becomes invalid. This can happen if between queuing the event and the execution of the work, the net-device was un-ensvaled and re-enslaved. Fix that by queuing a work with the data of the slave instead of the slave structure.
