They also fix a race condition between arp_validate setting and mode changing. Patch 01 - fixes the race condition between store_arp_validate and bond mode change by using rtnl for sync Patch 02 - fixes the possible de-sync state by setting/unsetting recv_probe if arp_interval is set/unset and also if arp_validate is set/unset v2: Fix the mode check in store_arp_validate Best regards, Nikolay Aleksandrov Nikolay Aleksandrov (2): bonding: fix store_arp_validate race with mode change bonding: fix bond_arp_rcv setting and arp validate desync state drivers/net/bonding/bond_main.c | 4 ++-- drivers/net/bonding/bond_sysfs.c | 31 +++++++++++++++++++++++++------ drivers/net/bonding/bonding.h | 1 + 3 files changed, 28 insertions(+), 8 deletions(-) -- 1.8.1.4
