[ Upstream commit accfe0e3 ] The commit 9195bb8e ("ipv6: improve ipv6_find_hdr() to skip empty routing headers") broke ipv6_find_hdr(). When a target is specified like IPPROTO_ICMPV6 ipv6_find_hdr() returns -ENOENT when it's found, not the header as expected. A part of IPVS is broken and possible also nft_exthdr_eval(). When target is -1 which it is most cases, it works. This patch exits the do while loop if the specific header is found so the nexthdr could be returned as expected. Reported-by:

[ Upstream commit 916e4cf4 ] Currently we generate a new fragmentation id on UFO segmentation. It is pretty hairy to identify the correct net namespace and dst there. Especially tunnels use IFF_XMIT_DST_RELEASE and thus have no skb_dst available at all. This causes unreliable or very predictable ipv6 fragmentation id generation while segmentation. Luckily we already have pregenerated the ip6_frag_id in ip6_ufo_append_data and can use it here. Signed-off-by:

[ Upstream commit f5ddcbbb ] This patch fixes two bugs in fastopen : 1) The tcp_sendmsg(..., @size) argument was ignored. Code was relying on user not fooling the kernel with iovec mismatches 2) When MTU is about 64KB, tcp_send_syn_data() attempts order-5 allocations, which are likely to fail when memory gets fragmented.

commit 04379dff upstream. This patch is a modification of the patch originally proposed by Xiaotian Feng <xtfeng@gmail.com>: https://lkml.org/lkml/2012/11/5/413 This new version disables DMA channel interrupts and ensures that the tasklet wil not be scheduled again before calling tasklet_kill(). Unfortunately the updated patch was not released at that time due to planned rework of Tsi721 mport driver to use threaded interrupts (which has yet to happen). Recently the issue was reported again: https://lkml.org/lkml/2014/2/19/762. Description from the original Xiaotian's patch: "Some drivers use tasklet_disable in device remove/release process, tasklet_disable will inc tasklet->count and return. If the tasklet is not handled yet under some softirq pressure, the tasklet will be placed on the tasklet_vec, never have a chance to be excuted. This might lead to a heavy loaded ksoftirqd, wakeup with pending_softirq, but tasklet is disabled. tasklet_kill should be used in this case." This patch is applicable to kernel versions starting from v3.5. Signed-off-by:

commit 791c9e02 upstream. dequeue_entity() is called when p->on_rq and sets se->on_rq = 0 which appears to guarentee that the !se->on_rq condition is met. If the task has done set_current_state(TASK_INTERRUPTIBLE) without schedule() the second condition will be met and vruntime will be incorrectly adjusted twice. In certain cases this can result in the task's vruntime never increasing past the vruntime of other tasks on the CFS' run queue, starving them of CPU time. This patch changes switched_from_fair() to use !p->on_rq instead of !se->on_rq. I'm able to cause a task with a priority of 120 to starve all other tasks with the same priority on an ARM platform running 3.2.51-rt72 PREEMPT RT by writing one character at time to a serial tty (16550 UART) in a tight loop. I'm also able to verify making this change corrects the problem on that platform and kernel version. Signed-off-by:

commit 15c34a76 upstream. Global quota files are accessed from different nodes. Thus we cannot cache offset of quota structure in the quota file after we drop our node reference count to it because after that moment quota structure may be freed and reallocated elsewhere by a different node resulting in corruption of quota file. Fix the problem by clearing dq_off when we are releasing dquot structure. We also remove the DB_READ_B handling because it is useless - DQ_ACTIVE_B is set iff DQ_READ_B is set. Signed-off-by:

commit da87ca4d upstream. Since commit 77873803 "net_dma: mark broken" we no longer pin dma engines active for the network-receive-offload use case. As a result the ->free_chan_resources() that occurs after the driver self test no longer has a NET_DMA induced ->alloc_chan_resources() to back it up. A late firing irq can lead to ksoftirqd spinning indefinitely due to the tasklet_disable() performed by ->free_chan_resources(). Only ->alloc_chan_resources() can clear this condition in affected kernels. This problem has been present since commit 3e037454 "I/OAT: Add support for MSI and MSI-X" in 2.6.24, but is now exposed. Given the NET_DMA use case is deprecated we can revisit moving the driver to use threaded irqs. For now, just tear down the irq and tasklet properly by: 1/ Disable the irq from triggering the tasklet 2/ Disable the irq from re-arming 3/ Flush inflight interrupts 4/ Flush the timer 5/ Flush inflight tasklets References: https://lkml.org/lkml/2014/1/27/282 https://lkml.org/lkml/2014/2/19/672 Cc: Ingo Molnar <mingo@elte.hu> Cc: Steven Rostedt <rostedt@goodmis.org> Reported-by:

commit e9baa9d9 upstream. It appears that in the DMA40 driver the DMA tasklet will very often dereference memory for a descriptor just free:d from the DMA40 slab. Nothing happens because no other part of the driver has yet had a chance to claim this memory, but it's really nasty to dereference free:d memory, so let's check the flag before the descriptor is free and store it in a bool variable.

commit 75135da0 upstream. pci_get_device() decrements the reference count of "from" (last argument) so when we break off the loop successfully we have only one device reference - and we don't know which device we have. If we want a reference to each device, we must take them explicitly and let the pci_get_device() walk complete to avoid duplicate references. This is serious, as over-putting device references will cause the device to eventually disappear. Without this fix, the kernel crashes after a few insmod/rmmod cycles. Tested on an Intel S7000FC4UR system with a 7300 chipset. Signed-off-by:

commit 6f58c780 upstream. A selective retransmission request (SRR) is a fibre-channel protocol control request which provides support for requesting retransmission of a data sequence in response to an issue such as frame loss or corruption. These events are experienced infrequently in fibre-channel based networks which makes it difficult to test and assess codepaths which handle these events. We were fortunate enough, for some definition of fortunate, to have a metro-area single-mode SAN link which, at 10 GBPS sustained load levels, would consistently generate SRR's in a SCST based target implementation using our SCST/in-kernel Qlogic target interface driver. In response to an SRR the in-kernel Qlogic target driver immediately panics resulting in a catastrophic storage failure for serviced initiators. The culprit was a debug statement in the qla_target.c file which does not verify that a pointer to the SCSI CDB is not null. The unchecked pointer dereference results in the kernel panic and resultant system failure. The other two references to the SCSI CDB by the SRR handling code use a ternary operator to verify a non-null pointer is being acted on. This patch simply adds a similar test to the implicated debug statement. This patch is a candidate for any stable kernel being maintained since it addresses a potentially catastrophic event with minimal downside. Signed-off-by:

commit e306dfd0 upstream. The frame PC value in the unwind code used to just take the saved LR value and use that. That's incorrect as a stack trace, since it shows the return path stack, not the call path stack. In particular, it shows faulty information in case the bl is done as the very last instruction of one label, since the return point will be in the next label. That can easily be seen with tail calls to panic(), which is marked __noreturn and thus doesn't have anything useful after it. Easiest here is to just correct the unwind code and do a -4, to get the actual call site for the backtrace instead of the return site. Signed-off-by:

commit f3713fd9 upstream. Commit 93e6f119 ("ipc/mqueue: cleanup definition names and locations") added global hardcoded limits to the amount of message queues that can be created. While these limits are per-namespace, reality is that it ends up breaking userspace applications. Historically users have, at least in theory, been able to create up to INT_MAX queues, and limiting it to just 1024 is way too low and dramatic for some workloads and use cases. For instance, Madars reports: "This update imposes bad limits on our multi-process application. As our app uses approaches that each process opens its own set of queues (usually something about 3-5 queues per process). In some scenarios we might run up to 3000 processes or more (which of-course for linux is not a problem). Thus we might need up to 9000 queues or more. All processes run under one user." Other affected users can be found in launchpad bug #1155695: https://bugs.launchpad.net/ubuntu/+source/manpages/+bug/1155695 Instead of increasing this limit, revert it entirely and fallback to the original way of dealing queue limits -- where once a user's resource limit is reached, and all memory is used, new queues cannot be created.

It turned out that when you have a group event, the code in __perf_event_exit_context() fails to remove the group siblings from the context. We then proceed with destroying and freeing the event, and when you re-plug the CPU and try and add another event to that CPU, things go *boom* because you've still got dead entries there.

commit 5bdfff96 upstream. When a kworker should die, the kworkre is notified through WORKER_DIE flag instead of kthread_should_stop(). This, IIRC, is primarily to keep the test synchronized inside worker_pool lock. WORKER_DIE is first set while holding pool->lock, the lock is dropped and kthread_stop() is called. Unfortunately, this means that there's a slight chance that the target kworker may see WORKER_DIE before kthread_stop() finishes and exits and frees the target task before or during kthread_stop(). Fix it by pinning the target task before setting WORKER_DIE and putting it after kthread_stop() is done. tj: Improved patch description and comment. Moved pinning above WORKER_DIE for better signify what it's protecting. Signed-off-by:
