[workqueue] WARNING: CPU: 0 PID: 76 at drivers/block/floppy.c:968 schedule_bh()

by Fengguang Wu

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master commit b22ce2785d97423846206cceec4efee0c4afd980 Author: Tejun Heo <tj(a)kernel.org> AuthorDate: Wed Aug 28 17:33:37 2013 -0400 Commit: Tejun Heo <tj(a)kernel.org> CommitDate: Thu Aug 29 09:19:28 2013 -0400 workqueue: cond_resched() after processing each work item If !PREEMPT, a kworker running work items back to back can hog CPU. This becomes dangerous when a self-requeueing work item which is waiting for something to happen races against stop_machine. Such self-requeueing work item would requeue itself indefinitely hogging the kworker and CPU it's running on while stop_machine would wait for that CPU to enter stop_machine while preventing anything else from happening on all other CPUs. The two would deadlock. Jamie Liu reports that this deadlock scenario exists around scsi_requeue_run_queue() and libata port multiplier support, where one port may exclude command processing from other ports. With the right timing, scsi_requeue_run_queue() can end up requeueing itself trying to execute an IO which is asked to be retried while another device has an exclusive access, which in turn can't make forward progress due to stop_machine. Fix it by invoking cond_resched() after executing each work item.

[timer] BUG: soft lockup - CPU#1 stuck for 23s! [swapper/0:1]

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master commit 1ead65812486cda65093683a99b8907a7242fa93 Merge: b6d739e b97f029 Author: Linus Torvalds <torvalds(a)linux-foundation.org> AuthorDate: Tue Apr 1 11:00:07 2014 -0700 Commit: Linus Torvalds <torvalds(a)linux-foundation.org> CommitDate: Tue Apr 1 11:00:07 2014 -0700 Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer changes from Thomas Gleixner: "This assorted collection provides: - A new timer based timer broadcast feature for systems which do not provide a global accessible timer device.

[ipv6] BUG kmalloc-512 (Not tainted): Object padding overwritten

by Fengguang Wu

Hi Eric, This is an old bug and not very reproducible, however is still showing up in current upstream and linux-next. git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master commit efe4208f47f907b86f528788da711e8ab9dea44d Author: Eric Dumazet <edumazet(a)google.com> AuthorDate: Thu Oct 3 15:42:29 2013 -0700 Commit: David S. Miller <davem(a)davemloft.net> CommitDate: Wed Oct 9 00:01:25 2013 -0400 ipv6: make lookups simpler and faster TCP listener refactoring, part 4 : To speed up inet lookups, we moved IPv4 addresses from inet to struct sock_common Now is time to do the same for IPv6, because it permits us to have fast lookups for all kind of sockets, including upcoming SYN_RECV. Getting IPv6 addresses in TCP lookups currently requires two extra cache lines, plus a dereference (and memory stall). inet6_sk(sk) does the dereference of inet_sk(__sk)->pinet6 This patch is way bigger than its IPv4 counter part, because for IPv4, we could add aliases (inet_daddr, inet_rcv_saddr), while on IPv6, it's not doable easily. inet6_sk(sk)->daddr becomes sk->sk_v6_daddr inet6_sk(sk)->rcv_saddr becomes sk->sk_v6_rcv_saddr And timewait socket also have tw->tw_v6_daddr & tw->tw_v6_rcv_saddr at the same offset. We get rid of INET6_TW_MATCH() as INET6_MATCH() is now the generic macro. Signed-off-by: Eric Dumazet <edumazet(a)google.com> Signed-off-by: David S.
