2013-10-24iser-target: check device before dereferencing its variableVu Pham1-1/+1
This patch changes isert_connect_release() to correctly check for the existence struct isert_device *device before checking for isert_device->use_frwr. Signed-off-by: Vu Pham <vu@mellanox.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2013-10-24raid5: avoid finding "discard" stripeShaohua Li1-0/+8
SCSI discard will damage discard stripe bio setting, eg, some fields are changed. If the stripe is reused very soon, we have wrong bios setting. We remove discard stripe from hash list, so next time the strip will be fully initialized. Suitable for backport to 3.7+.

2013-10-24md: avoid deadlock when md_set_badblocks.Bian Yu1-2/+3
When operate harddisk and hit errors, md_set_badblocks is called after scsi_restart_operations which already disabled the irq. but md_set_badblocks will call write_sequnlock_irq and enable irq. so softirq can preempt the current thread and that may cause a deadlock. I think this situation should use write_sequnlock_irqsave/irqrestore instead. I met the situation and the call trace is below: [ 638.919974] BUG: spinlock recursion on CPU#0, scsi_eh_13/1010 [ 638.921923] lock: 0xffff8800d4d51fc8, .magic: dead4ead, .owner: scsi_eh_13/1010, .owner_cpu: 0 [ 638.923890] CPU: 0 PID: 1010 Comm: scsi_eh_13 Not tainted 3.12.0-rc5+ #37 [ 638.925844] Hardware name: To be filled by O.E.M.

2013-10-24md: Fix skipping recovery for read-only arrays.Lukasz Dorau2-0/+2
Since: commit 7ceb17e87bde79d285a8b988cfed9eaeebe60b86 md: Allow devices to be re-added to a read-only array. spares are activated on a read-only array. In case of raid1 and raid10 personalities it causes that not-in-sync devices are marked in-sync without checking if recovery has been finished. If a read-only array is degraded and one of its devices is not in-sync (because the array has been only partially recovered) recovery will be skipped. This patch adds checking if recovery has been finished before marking a device in-sync for raid1 and raid10 personalities. In case of raid5 personality such condition is already present (at raid5.c:6029). Bug was introduced in 3.10 and causes data corruption.

2013-10-23[SCSI] sd: call blk_pm_runtime_init before add_diskAaron Lu1-1/+1
Sujit has found a race condition that would make q->nr_pending unbalanced, it occurs as Sujit explained: " sd_probe_async() -> add_disk() -> disk_add_event() -> schedule(disk_events_workfn) sd_revalidate_disk() blk_pm_runtime_init() return; Let's say the disk_events_workfn() calls sd_check_events() which tries to send test_unit_ready() and because of sd_revalidate_disk() trying to send another commands the test_unit_ready() might be re-queued as the tagged command queuing is disabled. So the race condition is - Thread 1 | Thread 2 sd_revalidate_disk() | sd_check_events() ...nr_pending = 0 as q->dev = NULL| scsi_queue_insert() blk_runtime_pm_init() | blk_pm_requeue_request() -> | nr_pending = -1 since | q->dev != NULL " The problem is, the test_unit_ready request doesn't get counted the first time it is queued, so the later decrement of q->nr_pending in blk_pm_requeue_request makes it unbalanced. Fix this by calling blk_pm_runtime_init before add_disk so that all requests initiated there will all be counted.

2013-10-23perf bench: Change the procps visible command-name of invididual benchmark ↵Ingo Molnar1-117/+122
tests plus cleanups Before this patch, looking at 'perf bench sched pipe' behavior over 'top' only told us that something related to perf is running: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 19934 mingo 20 0 54836 1296 952 R 18.6 0.0 0:00.56 perf 19935 mingo 20 0 54836 384 36 S 18.6 0.0 0:00.56 perf After the patch it's clearly visible what's going on: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 19744 mingo 20 0 125m 3536 2644 R 68.2 0.0 0:01.12 sched-pipe 19745 mingo 20 0 125m 1172 276 R 68.2 0.0 0:01.12 sched-pipe The benchmark-subsystem name is concatenated with the individual testcase name. Unfortunately 'perf top' does not show the reconfigured name, possibly because it caches ->comm[] values and does not recognize changes to them? Also clean up a few bits in builtin-bench.c while at it and reorganize the code and the output strings to be consistent. Use iterators to access the various arrays. Rename 'suites' concept to 'benchmark collection' and the 'bench_suite' to 'benchmark/bench'. The many repetitions of 'suite' made the code harder to read and understand. The new output is: comet:~/tip/tools/perf> ./perf bench Usage: perf bench [<common options>] <collection> <benchmark> [<options>] # List of all available benchmark collections: sched: Scheduler and IPC benchmarks mem: Memory access benchmarks numa: NUMA scheduling and MM benchmarks all: All benchmarks comet:~/tip/tools/perf> ./perf bench sched # List of available benchmarks for collection 'sched': messaging: Benchmark for scheduling and IPC pipe: Benchmark for pipe() between two processes all: Test all scheduler benchmarks comet:~/tip/tools/perf> ./perf bench mem # List of available benchmarks for collection 'mem': memcpy: Benchmark for memcpy() memset: Benchmark for memset() tests all: Test all memory benchmarks comet:~/tip/tools/perf> ./perf bench numa # List of available benchmarks for collection 'numa': mem: Benchmark for NUMA workloads all: Test all NUMA benchmarks Individual benchmark modules were not touched.

2013-10-23perf probe: Find fentry mcount fuzzed parameter locationMasami Hiramatsu1-8/+31
At this point, --fentry (mcount function entry) option for gcc fuzzes the debuginfo variable locations by skipping the mcount instruction offset (on x86, this is a 5 byte call instruction). This makes variable searching fail at the entry of functions which are mcount'ed. e.g.) Available variables at vfs_read @<vfs_read+0> (No matched variables) This patch adds additional location search at the function entry point to solve this issue, which tries to find the earliest address for the variable location. Note that this only works with function parameters (formal parameters) because any local variables should not exist on the function entry address (those are not initialized yet). With this patch, perf probe shows correct parameters if possible; # perf probe --vars vfs_read Available variables at vfs_read @<vfs_read+0> char* buf loff_t* pos size_t count struct file* file Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/20131011071025.15557.13275.stgit@udc4-manage.rcp.hitachi.co.jp Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2013-10-23clockevents: Sanitize ticks to nsec conversionThomas Gleixner1-15/+50
Marc Kleine-Budde pointed out, that commit 77cc982 "clocksource: use clockevents_config_and_register() where possible" caused a regression for some of the converted subarchs. The reason is, that the clockevents core code converts the minimal hardware tick delta to a nanosecond value for core internal usage. This conversion is affected by integer math rounding loss, so the backwards conversion to hardware ticks will likely result in a value which is less than the configured hardware limitation. The affected subarchs used their own workaround (SIGH!) which got lost in the conversion. The solution for the issue at hand is simple: adding evt->mult - 1 to the shifted value before the integer divison in the core conversion function takes care of it. But this only works for the case where for the scaled math mult/shift pair "mult <= 1 << shift" is true. For the case where "mult > 1 << shift" we can apply the rounding add only for the minimum delta value to make sure that the backward conversion is not less than the given hardware limit. For the upper bound we need to omit the rounding add, because the backwards conversion is always larger than the original latch value. That would violate the upper bound of the hardware device. Though looking closer at the details of that function reveals another bogosity: The upper bounds check is broken as well. Checking for a resulting "clc" value greater than KTIME_MAX after the conversion is pointless. The conversion does: u64 clc = (latch << evt->shift) / evt->mult; So there is no sanity check for (latch << evt->shift) exceeding the 64bit boundary. The latch argument is "unsigned long", so on a 64bit arch the handed in argument could easily lead to an unnoticed shift overflow. With the above rounding fix applied the calculation before the divison is: u64 clc = (latch << evt->shift) + evt->mult - 1; So we need to make sure, that neither the shift nor the rounding add is overflowing the u64 boundary.

2013-10-22Revert "bridge: only expire the mdb entry when query is received"Linus Lüssing3-22/+28
While this commit was a good attempt to fix issues occuring when no multicast querier is present, this commit still has two more issues: 1) There are cases where mdb entries do not expire even if there is a querier present. The bridge will unnecessarily continue flooding multicast packets on the according ports. 2) Never removing an mdb entry could be exploited for a Denial of Service by an attacker on the local link, slowly, but steadily eating up all memory. Actually, this commit became obsolete with "bridge: disable snooping if there is no querier" (b00589af3b) which included fixes for a few more cases. Therefore reverting the following commits (the commit stated in the commit message plus three of its follow up fixes): ==================== Revert "bridge: update mdb expiration timer upon reports." This reverts commit f144febd93d5ee534fdf23505ab091b2b9088edc. Revert "bridge: do not call setup_timer() multiple times" This reverts commit 1faabf2aab1fdaa1ace4e8c829d1b9cf7bfec2f1.
