Eric Dumazet 3db6482523 bonding: make tx_rebalance_counter an atomic ... commit dac8e00fb640e9569cdeefd3ce8a75639e5d0711 upstream. KCSAN reported a data-race [1] around tx_rebalance_counter which can be accessed from different contexts, without the protection of a lock/mutex. [1] BUG: KCSAN: data-race in bond_alb_init_slave / bond_alb_monitor write to 0xffff888157e8ca24 of 4 bytes by task 7075 on cpu 0: bond_alb_init_slave+0x713/0x860 drivers/net/bonding/bond_alb.c:1613 bond_enslave+0xd94/0x3010 drivers/net/bonding/bond_main.c:1949 do_set_master net/core/rtnetlink.c:2521 [inline] __rtnl_newlink net/core/rtnetlink.c:3475 [inline] rtnl_newlink+0x1298/0x13b0 net/core/rtnetlink.c:3506 rtnetlink_rcv_msg+0x745/0x7e0 net/core/rtnetlink.c:5571 netlink_rcv_skb+0x14e/0x250 net/netlink/af_netlink.c:2491 rtnetlink_rcv+0x18/0x20 net/core/rtnetlink.c:5589 netlink_unicast_kernel net/netlink/af_netlink.c:1319 [inline] netlink_unicast+0x5fc/0x6c0 net/netlink/af_netlink.c:1345 netlink_sendmsg+0x6e1/0x7d0 net/netlink/af_netlink.c:1916 sock_sendmsg_nosec net/socket.c:704 [inline] sock_sendmsg net/socket.c:724 [inline] ____sys_sendmsg+0x39a/0x510 net/socket.c:2409 ___sys_sendmsg net/socket.c:2463 [inline] __sys_sendmsg+0x195/0x230 net/socket.c:2492 __do_sys_sendmsg net/socket.c:2501 [inline] __se_sys_sendmsg net/socket.c:2499 [inline] __x64_sys_sendmsg+0x42/0x50 net/socket.c:2499 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x44/0xd0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x44/0xae read to 0xffff888157e8ca24 of 4 bytes by task 1082 on cpu 1: bond_alb_monitor+0x8f/0xc00 drivers/net/bonding/bond_alb.c:1511 process_one_work+0x3fc/0x980 kernel/workqueue.c:2298 worker_thread+0x616/0xa70 kernel/workqueue.c:2445 kthread+0x2c7/0x2e0 kernel/kthread.c:327 ret_from_fork+0x1f/0x30 value changed: 0x00000001 -> 0x00000064 Reported by Kernel Concurrency Sanitizer on: CPU: 1 PID: 1082 Comm: kworker/u4:3 Not tainted 5.16.0-rc3-syzkaller #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 Workqueue: bond1 bond_alb_monitor Fixes: 1da177e4c3 ("Linux-2.6.12-rc2") Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: syzbot <syzkaller@googlegroups.com> Signed-off-by: David S.
