Pull target fix from Nicholas Bellinger: "So just a single target fix for v3.7.0 this time around from Roland to address a aborted command bug w/ tcm_qla2xxx fabric ports. Also, there is one outstanding IBLOCK + virtio-blk bug that is still being tracked down effecting v3.6.x, but AFAICT thus far this appears to be a bug outside of target code." * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: target: Fix handling of aborted commands

With "mm: vmscan: scale number of pages reclaimed by reclaim/compaction based on failures" reverted, Zdenek Kabelac reported the following Hmm, so it's just took longer to hit the problem and observe kswapd0 spinning on my CPU again - it's not as endless like before - but still it easily eats minutes - it helps to turn off Firefox or TB (memory hungry apps) so kswapd0 stops soon - and restart those apps again. (And I still have like >1GB of cached memory) kswapd0 R running task 0 30 2 0x00000000 Call Trace: preempt_schedule+0x42/0x60 _raw_spin_unlock+0x55/0x60 put_super+0x31/0x40 drop_super+0x22/0x30 prune_super+0x149/0x1b0 shrink_slab+0xba/0x510 The sysrq+m indicates the system has no swap so it'll never reclaim anonymous pages as part of reclaim/compaction. That is one part of the problem but not the root cause as file-backed pages could also be reclaimed. The likely underlying problem is that kswapd is woken up or kept awake for each THP allocation request in the page allocator slow path. If compaction fails for the requesting process then compaction will be deferred for a time and direct reclaim is avoided. However, if there are a storm of THP requests that are simply rejected, it will still be the the case that kswapd is awake for a prolonged period of time as pgdat->kswapd_max_order is updated each time. This is noticed by the main kswapd() loop and it will not call kswapd_try_to_sleep(). Instead it will loopp, shrinking a small number of pages and calling shrink_slab() on each iteration. This patch defers when kswapd gets woken up for THP allocations. For !THP allocations, kswapd is always woken up. For THP allocations, kswapd is woken up iff the process is willing to enter into direct reclaim/compaction. [akpm@linux-foundation.org: fix typo in comment] Signed-off-by:

Johannes Weiner authored
Kswapd does not in all places have the same criteria for a balanced zone. Zones are only being reclaimed when their high watermark is breached, but compaction checks loop over the zonelist again when the zone does not meet the low watermark plus two times the size of the allocation. This gets kswapd stuck in an endless loop over a small zone, like the DMA zone, where the high watermark is smaller than the compaction requirement. Add a function, zone_balanced(), that checks the watermark, and, for higher order allocations, if compaction has enough free memory. Then use it uniformly to check for balanced zones. This makes sure that when the compaction watermark is not met, at least reclaim happens and progress is made - or the zone is declared unreclaimable at some point and skipped entirely. Signed-off-by:

Commit ef6c5be6 ("fix incorrect NR_FREE_PAGES accounting (appears like memory leak)") fixes a NR_FREE_PAGE accounting leak but missed the return value which was also missed by this reviewer until today. That return value is used by compaction when adding pages to a list of isolated free pages and without this follow-up fix, there is a risk of free list corruption. Signed-off-by:

Trinity (the syscall fuzzer) discovered a memory leak in SCTP, reproducible e.g. with the sendto() syscall by passing invalid user space pointer in the second argument: #include <string.h> #include <arpa/inet.h> #include <sys/socket.h> int main(void) { int fd; struct sockaddr_in sa; fd = socket(AF_INET, SOCK_STREAM, 132 /*IPPROTO_SCTP*/); if (fd < 0) return 1; memset(&sa, 0, sizeof(sa)); sa.sin_family = AF_INET; sa.sin_addr.s_addr = inet_addr("127.0.0.1"); sa.sin_port = htons(11111); sendto(fd, NULL, 1, 0, (struct sockaddr *)&sa, sizeof(sa)); return 0; } As far as I can tell, the leak has been around since ~2003.

The SP804 driver statically initialises the cpumask of the clock event device to be cpu_all_mask, which is derived from the compile-time constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt controller handling the sp804 doesn't have the irq_set_affinity callback on the irq_chip, because the common timer code fails to identify the device as cpu-local and ends up treating it as a broadcast device instead. This patch fixes the problem by using cpu_possible_mask at runtime, which will correctly represent the possible CPUs when SMP_ON_UP is being used. Signed-off-by:

It just doesn't work (yeah took us a while to figure out), leading to jittery outputs in the best case. - Revert rc6 for ilk again. It seems to help a few of the gpu hang reporters at least, and it's definitely the best we've got. Head-against-the-wall-banging is still ongoing for what really breaks (and how we can reproduce the non-rc6 hangs and how to reproduce on gen4). * 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel: Revert "drm/i915: enable rc6 on ilk again" drm/i915: do not default to 18 bpp for eDP if missing from VBT drm/i915: disable cloning on sdvo

Dave Jones reported a bug with futex_lock_pi() that his trinity test exposed. Sometime between queue_me() and taking the q.lock_ptr, the lock_ptr became NULL, resulting in a crash. While futex_wake() is careful to not call wake_futex() on futex_q's with a pi_state or an rt_waiter (which are either waiting for a futex_unlock_pi() or a PI futex_requeue()), futex_wake_op() and futex_requeue() do not perform the same test. Update futex_wake_op() and futex_requeue() to test for q.pi_state and q.rt_waiter and abort with -EINVAL if detected. To ensure any future breakage is caught, add a WARN() to wake_futex() if the same condition is true. This fix has seen 3 hours of testing with "trinity -c futex" on an x86_64 VM with 4 CPUS.

In get_sample_period(), unsigned long is not enough: watchdog_thresh * 2 * (NSEC_PER_SEC / 5) case1: watchdog_thresh is 10 by default, the sample value will be: 0xEE6B2800 case2: set watchdog_thresh is 20, the sample value will be: 0x1 DCD6 5000 In case2, we need use u64 to express the sample period. Otherwise, changing the threshold thru proc often can not be successful. Signed-off-by:
