[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

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]
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 1ead65812486cda65093683a99b8907a7242fa93
Merge: b6d739e b97f029
Author: Linus Torvalds <torvalds(a)linux-foundation.org>

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. That allows those
systems to put CPUs into deep idle states where the per cpu timer
device stops.
- A few NOHZ_FULL related improvements to the timer wheel
- The usual updates to timer devices found in ARM SoCs
- Small improvements and updates all over the place"

[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.
