So the basic workflow is, for example, as follows: while [ 1 ]; do slabinfo -X -N 2 >> stats; sleep 1; done ^C slabinfo-gnuplot.sh stats The last command will produce 3 png files (and 3 stats files) -- graph of slabinfo totals -- graph of slabs by size -- graph of slabs by loss It's also possible to select a range of records for plotting (a range of collected slabinfo outputs) via `-r 10,100` (for example); and compare totals from several measurements (to visially compare slabs behaviour (10,50 range)) using pre-parsed totals files: slabinfo-gnuplot.sh -r 10,50 -t stats-totals1 .. stats-totals2 This also, technically, supports ktest. Upload new slabinfo to target, collect the stats and give the resulting stats file to slabinfo-gnuplot This patch (of 8): Use getopt constants in `struct option' ->has_arg instead of numerical representations.

Currently, when kmem_cache_destroy() is called for a global cache, we print a warning for each per memcg cache attached to it that has active objects (see shutdown_cache). This is redundant, because it gives no new information and only clutters the log. If a cache being destroyed has active objects, there must be a memory leak in the module that created the cache, and it does not matter if the cache was used by users in memory cgroups or not. This patch moves the warning from shutdown_cache(), which is called for shutting down both global and per memcg caches, to kmem_cache_destroy(), so that the warning is only printed once if there are objects left in the cache being destroyed.

Currently, we do not clear pointers to per memcg caches in the memcg_params.memcg_caches array when a global cache is destroyed with kmem_cache_destroy. This is fine if the global cache does get destroyed. However, a cache can be left on the list if it still has active objects when kmem_cache_destroy is called (due to a memory leak). If this happens, the entries in the array will point to already freed areas, which is likely to result in data corruption when the cache is reused (via slab merging). Signed-off-by:

Theoretically it is possible that the watchdog timer expires right at the time when a user sets 'watchdog_thresh' to zero (note: this disables the lockup detectors). In this scenario, the is_softlockup() function - which is called by the timer - could produce a false positive. Fix this by checking the current value of 'watchdog_thresh'. Signed-off-by:

watchdog_{park|unpark}_threads() are now called in code paths that protect themselves against CPU hotplug, so {get|put}_online_cpus() calls are redundant and can be removed. Signed-off-by: -
Ulrich Obergfell authored
The handler functions for watchdog parameters in /proc/sys/kernel do not protect themselves against races with CPU hotplug. Hence, theoretically it is possible that a new watchdog thread is started on a hotplugged CPU while a parameter is being modified, and the thread could thus use a parameter value that is 'in transition'. For example, if 'watchdog_thresh' is being set to zero (note: this disables the lockup detectors) the thread would erroneously use the value zero as the sample period. To avoid such races and to keep the /proc handler code consistent, call {get|put}_online_cpus() in proc_watchdog_common() {get|put}_online_cpus() in proc_watchdog_thresh() {get|put}_online_cpus() in proc_watchdog_cpumask() Signed-off-by: -

The lockup detector suspend/resume interface that was introduced by commit 8c073d27 ("watchdog: introduce watchdog_suspend() and watchdog_resume()") does not protect itself against races with CPU hotplug. Hence, theoretically it is possible that a new watchdog thread is started on a hotplugged CPU while the lockup detector is suspended, and the thread could thus interfere unexpectedly with the code that requested to suspend the lockup detector. Avoid the race by calling get_online_cpus() in lockup_detector_suspend() put_online_cpus() in lockup_detector_resume() Signed-off-by:

The only way to enable a hardlockup to panic the machine is to set 'nmi_watchdog=panic' on the kernel command line. This makes it awkward for end users and folks who want to run automate tests (like myself). Mimic the softlockup_panic knob and create a /proc/sys/kernel/hardlockup_panic knob. Signed-off-by:

In many cases of hardlockup reports, it's actually not possible to know why it triggered, because the CPU that got stuck is usually waiting on a resource (with IRQs disabled) in posession of some other CPU is holding. IOW, we are often looking at the stacktrace of the victim and not the actual offender. Introduce sysctl / cmdline parameter that makes it possible to have hardlockup detector perform all-CPU backtrace. Signed-off-by:

If kthread_park() returns an error, watchdog_park_threads() should not blindly 'roll back' the already parked threads to the unparked state. Instead leave it up to the callers to handle such errors appropriately in their context. For example, it is redundant to unpark the threads if the lockup detectors will soon be disabled by the callers anyway. Signed-off-by:

Ulrich Obergfell authored
The original watchdog_park_threads() function that was introduced by commit 81a4beef ("watchdog: introduce watchdog_park_threads() and watchdog_unpark_threads()") takes a very simple approach to handle errors returned by kthread_park(): It attempts to roll back all watchdog threads to the unparked state. However, this may be undesired behaviour from the perspective of the caller which may want to handle errors as appropriate in its specific context. Currently, there are two possible call chains: - watchdog suspend/resume interface lockup_detector_suspend watchdog_park_threads - write to parameters in /proc/sys/kernel proc_watchdog_update watchdog_enable_all_cpus update_watchdog_all_cpus watchdog_park_threads Instead of 'blindly' attempting to unpark the watchdog threads if a kthread_park() call fails, the new approach is to disable the lockup detectors in the above call chains. Failure becomes visible to the user as follows: - error messages from lockup_detector_suspend() or watchdog_enable_all_cpus() - the state that can be read from /proc/sys/kernel/watchdog_enabled - the 'write' system call in the latter call chain returns an error I did not experience kthread_park() failures in practice, I used some instrumentation to fake error returns from kthread_park() in order to test the patches. This patch (of 5): Restore the previous value of watchdog_thresh _and_ sample_period if proc_watchdog_update() returns an error. The variables must be consistent to avoid false positives of the lockup detectors. Signed-off-by:

Make struct callback_head aligned to size of pointer. On most architectures it happens naturally due ABI requirements, but some architectures (like CRIS) have weird ABI and we need to ask it explicitly. The alignment is required to guarantee that bits 0 and 1 of @next will be clear under normal conditions -- as long as we use call_rcu(), call_rcu_bh(), call_rcu_sched(), or call_srcu() to queue callback. This guarantee is important for few reasons: - future call_rcu_lazy() will make use of lower bits in the pointer; - the structure shares storage spacer in struct page with @compound_head, which encode PageTail() in bit 0. The guarantee is needed to avoid false-positive PageTail(). False postive PageTail() caused crash on crisv32[1]. It happend due misaligned task_struct->rcu, which was byte-aligned.

Currently cluster allocation is always trying to find a victim chain (a chian has most space), and this may lead to poor performance because of discontiguous allocation in some scenarios. Our test case is block size 4k, cluster size 1M and mount option with localalloc=2048 (2G), since a gd is 32256M (about 31.5G) and a localalloc window is only 2G, creating 50G file will result in 2G from gd0, 2G from gd1, ... One way to improve performance is enlarge localalloc window size (max 31104M), but this will make end user feel that about 30G is suddenly "missing", and localalloc currently do not support steal, which means one node cannot use another node's localalloc even it is not used in fact. So using the last gd to record the allocation and continues with the gd if it has enough space for a localalloc window can make the allocation as more contiguous as possible. Our test result is below (evaluated in IOPS), which is using iometer running in VM, dynamic vhd virtual disk stored in ocfs2.

The comment here says that it is checking for invalid bits. But, the mask is *actually* checking to ensure that _any_ valid bit is set, which is quite different. Without this check, an unexpected bit could get set on an inotify object. Since these bits are also interpreted by the fsnotify/dnotify code, there is the potential for an object to be mishandled inside the kernel. For instance, can we be sure that setting the dnotify flag FS_DN_RENAME on an inotify watch is harmless? Add the actual check which was intended. Retain the existing inotify bits are being added to the watch. Plus, this is existing behavior which would be nice to preserve. I did a quick sniff test that inotify functions and that my 'inotify-tools' package passes 'make check'. Signed-off-by:

There was a report that my patch: inotify: actually check for invalid bits in sys_inotify_add_watch() broke CRIU. The reason is that CRIU looks up raw flags in /proc/$pid/fdinfo/* to figure out how to rebuild inotify watches and then passes those flags directly back in to the inotify API. One of those flags (FS_EVENT_ON_CHILD) is set in mark->mask, but is not part of the inotify API. It is used inside the kernel to _implement_ inotify but it is not and has never been part of the API. My patch above ensured that we only allow bits which are part of the API (IN_ALL_EVENTS). This broke CRIU. FS_EVENT_ON_CHILD is really internal to the kernel. It is set _anyway_ on all inotify marks. So, CRIU was really just trying to set a bit that was already set. This patch hides that bit from fdinfo. CRIU will not see the bit, not try to set it, and should work as before. We should not have been exposing this bit in the first place, so this is a good patch independent of the CRIU problem. Signed-off-by:Andrey Wagin <avagin@gmail.com> Acked-by:
