On some archs, dump_stack() prints\nextra information - pid, utsname and so on - in addition to the\nbacktrace while the two are identical on other archs.\n\nThe usages in arch-independent code of the two functions indicate\nshow_stack(NULL, NULL) should print out bare backtrace while\ndump_stack() is used for debugging purposes when something went wrong,\nso it does make sense to print additional information on the task which\ntriggered dump_stack().\n\nThere\u0027s no reason to require archs to implement two separate but mostly\nidentical functions. It leads to unnecessary subtle information.\n\nThis patch expands the dummy fallback dump_stack() implementation in\nlib/dump_stack.c such that it prints out debug information (taken from\nx86) and invokes show_stack(NULL, NULL) and drops arch-specific\ndump_stack() implementations in all archs except blackfin. Blackfin\u0027s\ndump_stack() does something wonky that I don\u0027t understand.\n\nDebug information can be printed separately by calling\ndump_stack_print_info() so that arch-specific dump_stack()\nimplementation can still emit the same debug information. This is used\nin blackfin.\n\nThis patch brings the following behavior changes.\n\n* On some archs, an extra level in backtrace for show_stack() could be\n printed. This is because the top frame was determined in\n dump_stack() on those archs while generic dump_stack() can\u0027t do that\n reliably. It can be compensated by inlining dump_stack() but not\n sure whether that\u0027d be necessary.\n\n* Most archs didn\u0027t use to print debug info on dump_stack(). They do\n now.\n\nAn example WARN dump follows.\n\n WARNING: at kernel/workqueue.c:4841 init_workqueues+0x35/0x505()\n Hardware name: empty\n Modules linked in:\n CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.9.0-rc1-work+ #9\n 0000000000000009 ffff88007c861e08 ffffffff81c614dc ffff88007c861e48\n ffffffff8108f50f ffffffff82228240 0000000000000040 ffffffff8234a03c\n 0000000000000000 0000000000000000 0000000000000000 ffff88007c861e58\n Call Trace:\n [\u003cffffffff81c614dc\u003e] dump_stack+0x19/0x1b\n [\u003cffffffff8108f50f\u003e] warn_slowpath_common+0x7f/0xc0\n [\u003cffffffff8108f56a\u003e] warn_slowpath_null+0x1a/0x20\n [\u003cffffffff8234a071\u003e] init_workqueues+0x35/0x505\n ...\n\nv2: CPU number added to the generic debug info as requested by s390\n folks and dropped the s390 specific dump_stack(). This loses %ksp\n from the debug message which the maintainers think isn\u0027t important\n enough to keep the s390-specific dump_stack() implementation.\n\n dump_stack_print_info() is moved to kernel/printk.c from\n lib/dump_stack.c. Because linkage is per objecct file,\n dump_stack_print_info() living in the same lib file as generic\n dump_stack() means that archs which implement custom dump_stack()\n - at this point, only blackfin - can\u0027t use dump_stack_print_info()\n as that will bring in the generic version of dump_stack() too. v1\n The v1 patch broke build on blackfin due to this issue. The build\n breakage was reported by Fengguang Wu.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: David S.

Implement shadow timekeeper to shorten in kernel reader side\n blocking, by Thomas Gleixner.\n\n - Posix timers enhancements by Pavel Emelyanov:\n\n - allocate timer ID per process, so that exact timer ID allocations\n can be re-created be checkpoint/restore code.\n\n - debuggability and tooling (/proc/PID/timers, etc.) improvements.\n\n - suspend/resume enhancements by Feng Tang: on certain new Intel Atom\n processors (Penwell and Cloverview), there is a feature that the\n TSC won\u0027t stop in S3 state, so the TSC value won\u0027t be reset to 0\n after resume. This can be taken advantage of by the generic via\n the CLOCK_SOURCE_SUSPEND_NONSTOP flag: instead of using the RTC to\n recover/approximate sleep time, the main (and precise) clocksource\n can be used.\n\n - Fix /proc/timer_list for 4096 CPUs by Nathan Zimmer: on so many\n CPUs the file goes beyond 4MB of size and thus the current\n simplistic seqfile approach fails. Convert /proc/timer_list to a\n proper seq_file with its own iterator.\n\n - Cleanups and refactorings of the core timekeeping code by John\n Stultz.\n\n - International Atomic Clock time is managed by the NTP code\n internally currently but not exposed externally. Separate the TAI\n code out and add CLOCK_TAI support and TAI support to the hrtimer\n and posix-timer code, by John Stultz.\n\n - Add deep idle support enhacement to the broadcast clockevents core\n timer code, by Daniel Lezcano: add an opt-in CLOCK_EVT_FEAT_DYNIRQ\n clockevents feature (which will be utilized by future clockevents\n driver updates), which allows the use of IRQ affinities to avoid\n spurious wakeups of idle CPUs -

Fixes and a lot of cleanups. Locking cleanup is finally complete.\n cgroup_mutex is no longer exposed to individual controlelrs which\n used to cause nasty deadlock issues. Li fixed and cleaned up quite a\n bit including long standing ones like racy cgroup_path().\n\n - device cgroup now supports proper hierarchy thanks to Aristeu.\n\n - perf_event cgroup now supports proper hierarchy.\n\n - A new mount option \"__DEVEL__sane_behavior\" is added. As indicated\n by the name, this option is to be used for development only at this\n point and generates a warning message when used. Unfortunately,\n cgroup interface currently has too many brekages and inconsistencies\n to implement a consistent and unified hierarchy on top. The new flag\n is used to collect the behavior changes which are necessary to\n implement consistent unified hierarchy. It\u0027s likely that this flag\n won\u0027t be used verbatim when it becomes ready but will be enabled\n implicitly along with unified hierarchy.\n\n The option currently disables some of broken behaviors in cgroup core\n and also .use_hierarchy switch in memcg (will be routed through -mm),\n which can be used to make very unusual hierarchy where nesting is\n partially honored. It will also be used to implement hierarchy\n support for blk-throttle which would be impossible otherwise without\n introducing a full separate set of control knobs.\n\n This is essentially versioning of interface which isn\u0027t very nice but\n at this point I can\u0027t see any other options which would allow keeping\n the interface the same while moving towards hierarchy behavior which\n is at least somewhat sane. The planned unified hierarchy is likely\n to require some level of adaptation from userland anyway, so I think\n it\u0027d be best to take the chance and update the interface such that\n it\u0027s supportable in the long term.\n\n Maintaining the existing interface does complicate cgroup core but\n shouldn\u0027t put too much strain on individual controllers and I think\n it\u0027d be manageable for the foreseeable future.

The changes achieve\n the followings.\n\n - WQ_UNBOUND workqueues - the workqueues which are per-cpu - are\n updated to be able to interface with multiple backend worker pools.\n This involved a lot of churning but the end result seems actually\n neater as unbound workqueues are now a lot closer to per-cpu ones.\n\n - The ability to interface with multiple backend worker pools are\n used to implement unbound workqueues with custom attributes.\n Currently the supported attributes are the nice level and CPU\n affinity. It may be expanded to include cgroup association in\n future. The attributes can be specified either by calling\n apply_workqueue_attrs() or through /sys/bus/workqueue/WQ_NAME/* if\n the workqueue in question is exported through sysfs.\n\n The backend worker pools are keyed by the actual attributes and\n shared by any workqueues which share the same attributes. When\n attributes of a workqueue are changed, the workqueue binds to the\n worker pool with the specified attributes while leaving the work\n items which are already executing in its previous worker pools\n alone.\n\n This allows converting custom worker pool implementations which\n want worker attribute tuning to use workqueues. The writeback pool\n is already converted in block tree and there are a couple others\n are likely to follow including btrfs io workers.\n\n - WQ_UNBOUND\u0027s ability to bind to multiple worker pools is also used\n to make it NUMA-aware. Because there\u0027s no association between work\n item issuer and the specific worker assigned to execute it, before\n this change, using unbound workqueue led to unnecessary cross-node\n bouncing and it couldn\u0027t be helped by autonuma as it requires tasks\n to have implicit node affinity and workers are assigned randomly.\n\n After these changes, an unbound workqueue now binds to multiple\n NUMA-affine worker pools so that queued work items are executed in\n the same node. This is turned on by default but can be disabled\n system-wide or for individual workqueues.\n\n Crypto was requesting NUMA affinity as encrypting data across\n different nodes can contribute noticeable overhead and doing it\n per-cpu was too limiting for certain cases and IO throughput could\n be bottlenecked by one CPU being fully occupied while others have\n idle cycles.\n\n While the new features required a lot of changes including\n restructuring locking, it didn\u0027t complicate the execution paths much.\n The unbound workqueue handling is now closer to per-cpu ones and the\n new features are implemented by simply associating a workqueue with\n different sets of backend worker pools without changing queue,\n execution or flush paths.\n\n As such, even though the amount of change is very high, I feel\n relatively safe in that it isn\u0027t likely to cause subtle issues with\n basic correctness of work item execution and handling. If something\n is wrong, it\u0027s likely to show up as being associated with worker pools\n with the wrong attributes or OOPS while workqueue attributes are being\n changed or during CPU hotplug.\n\n While this creates more backend worker pools, it doesn\u0027t add too many\n more workers unless, of course, there are many workqueues with unique\n combinations of attributes. Assuming everything else is the same,\n NUMA awareness costs an extra worker pool per NUMA node with online\n CPUs.\n\n There are also a couple things which are being routed outside the\n workqueue tree.\n\n - block tree pulled in workqueue for-3.10 so that writeback worker\n pool can be converted to unbound workqueue with sysfs control\n exposed. This simplifies the code, makes writeback workers\n NUMA-aware and allows tuning nice level and CPU affinity via sysfs.\n\n - The conversion to workqueue means that there\u0027s no 1:1 association\n between a specific worker, which makes writeback folks unhappy as\n they want to be able to tell which filesystem caused a problem from\n backtrace on systems with many filesystems mounted.

Many of these users are in obscure parts of the\nkernel, and I don\u0027t have a good way to test some of them. The change is\npretty straightforward though, so hopefully it won\u0027t be an issue.\n\nThere is one other cyclic user of idr_alloc that I didn\u0027t touch in\nipc/util.c.

It\u0027s prone to -ENOSPC\n after the first wraparound. There are several cyclic users in the\n kernel and I think it probably would be best to implement cyclic\n support in idr.\n\nThis patch does that by adding new idr_alloc_cyclic function that such\nusers in the kernel can use. With this, there\u0027s no need for a caller to\nkeep track of the last value used as that\u0027s now tracked internally. This\nshould prevent the ENOSPC problems that can hit when the \"last allocated\"\ncounter exceeds INT_MAX.\n\nLater patches will convert existing cyclic users to the new interface.\n\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nReviewed-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: \"David S.

The levels are defined like this:\n\nThe \"low\" level means that the system is reclaiming memory for new\nallocations. Monitoring this reclaiming activity might be useful for\nmaintaining cache level. Upon notification, the program (typically\n\"Activity Manager\") might analyze vmstat and act in advance (i.e.\nprematurely shutdown unimportant services).\n\nThe \"medium\" level means that the system is experiencing medium memory\npressure, the system might be making swap, paging out active file\ncaches, etc. Upon this event applications may decide to further analyze\nvmstat/zoneinfo/memcg or internal memory usage statistics and free any\nresources that can be easily reconstructed or re-read from a disk.\n\nThe \"critical\" level means that the system is actively thrashing, it is\nabout to out of memory (OOM) or even the in-kernel OOM killer is on its\nway to trigger. Applications should do whatever they can to help the\nsystem. It might be too late to consult with vmstat or any other\nstatistics, so it\u0027s advisable to take an immediate action.\n\nThe events are propagated upward until the event is handled, i.e. the\nevents are not pass-through. Here is what this means: for example you\nhave three cgroups: A-\u003eB-\u003eC. Now you set up an event listener on\ncgroups A, B and C, and suppose group C experiences some pressure. In\nthis situation, only group C will receive the notification, i.e. groups\nA and B will not receive it. This is done to avoid excessive\n\"broadcasting\" of messages, which disturbs the system and which is\nespecially bad if we are low on memory or thrashing. So, organize the\ncgroups wisely, or propagate the events manually (or, ask us to\nimplement the pass-through events, explaining why would you need them.)\n\nPerformance wise, the memory pressure notifications feature itself is\nlightweight and does not require much of bookkeeping, in contrast to the\nrest of memcg features. Unfortunately, as of current memcg\nimplementation, pages accounting is an inseparable part and cannot be\nturned off. The good news is that there are some efforts[1] to improve\nthe situation; plus, implementing the same, fully API-compatible[2]\ninterface for CONFIG_MEMCG\u003dn case (e.g. embedded) is also a viable\noption, so it will not require any changes on the userland side.\n\n[1] http://permalink.gmane.org/gmane.linux.kernel.cgroups/6291\n[2] http://lkml.org/lkml/2013/2/21/454\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: fix CONFIG_CGROPUPS\u003dn warnings]\nSigned-off-by: Anton Vorontsov \u003canton.vorontsov@linaro.org\u003e\nAcked-by: Kirill A.

This was done so that a\nuser could recover if they launched a memory hogging process. Without the\nreserve, a user would easily run into a message such as:\n\nbash: fork: Cannot allocate memory\n\n2. admin reserve\n\nAdditionally, a hardcoded 3% of free memory is reserved for root in both\novercommit \u0027guess\u0027 and \u0027never\u0027 modes. This was intended to prevent a\nscenario where root-cant-log-in and perform recovery operations.\n\nNote that this reserve shrinks, and doesn\u0027t guarantee a useful reserve.\n\nMotivation\n\nThe two hardcoded memory reserves should be updated to account for current\nmemory sizes.\n\nAlso, the admin reserve would be more useful if it didn\u0027t shrink too much.\n\nWhen the current code was originally written, 1GB was considered\n\"enterprise\". Now the 3% reserve can grow to multiple GB on large memory\nsystems, and it only needs to be a few hundred MB at most to enable a user\nor admin to recover a system with an unwanted memory hogging process.\n\nI\u0027ve found that reducing these reserves is especially beneficial for a\nspecific type of application load:\n\n * single application system\n * one or few processes (e.g. one per core)\n * allocating all available memory\n * not initializing every page immediately\n * long running\n\nI\u0027ve run scientific clusters with this sort of load. A long running job\nsometimes failed many hours (weeks of CPU time) into a calculation. They\nweren\u0027t initializing all of their memory immediately, and they weren\u0027t\nusing calloc, so I put systems into overcommit \u0027never\u0027 mode. These\nclusters run diskless and have no swap.\n\nHowever, with the current reserves, a user wishing to allocate as much\nmemory as possible to one process may be prevented from using, for\nexample, almost 2GB out of 32GB.\n\nThe effect is less, but still significant when a user starts a job with\none process per core. I have repeatedly seen a set of processes\nrequesting the same amount of memory fail because one of them could not\nallocate the amount of memory a user would expect to be able to allocate.\nFor example, Message Passing Interfce (MPI) processes, one per core. And\nit is similar for other parallel programming frameworks.\n\nChanging this reserve code will make the overcommit never mode more useful\nby allowing applications to allocate nearly all of the available memory.\n\nAlso, the new admin_reserve_kbytes will be safer than the current behavior\nsince the hardcoded 3% of available memory reserve can shrink to something\nuseless in the case where applications have grabbed all available memory.\n\nRisks\n\n* \"bash: fork: Cannot allocate memory\"\n\n The downside of the first patch-- which creates a tunable user reserve\n that is only used in overcommit \u0027never\u0027 mode--is that an admin can set\n it so low that a user may not be able to kill their process, even if\n they already have a shell prompt.\n\n Of course, a user can get in the same predicament with the current 3%\n reserve--they just have to launch processes until 3% becomes negligible.\n\n* root-cant-log-in problem\n\n The second patch, adding the tunable rootuser_reserve_pages, allows\n the admin to shoot themselves in the foot by setting it too small. They\n can easily get the system into a state where root-can\u0027t-log-in.\n\n However, the new admin_reserve_kbytes will be safer than the current\n behavior since the hardcoded 3% of available memory reserve can shrink\n to something useless in the case where applications have grabbed all\n available memory.\n\nAlternatives\n\n * Memory cgroups provide a more flexible way to limit application memory.\n\n Not everyone wants to set up cgroups or deal with their overhead.\n\n * We could create a fourth overcommit mode which provides smaller reserves.\n\n The size of useful reserves may be drastically different depending\n on the whether the system is embedded or enterprise.\n\n * Force users to initialize all of their memory or use calloc.\n\n Some users don\u0027t want/expect the system to overcommit when they malloc.\n Overcommit \u0027never\u0027 mode is for this scenario, and it should work well.\n\nThe new user and admin reserve tunables are simple to use, with low\noverhead compared to cgroups. The patches preserve current behavior where\n3% of memory is less than 128MB, except that the admin reserve doesn\u0027t\nshrink to an unusable size under pressure. The code allows admins to tune\nfor embedded and enterprise usage.\n\nFAQ\n\n * How is the root-cant-login problem addressed?\n What happens if admin_reserve_pages is set to 0?\n\n Root is free to shoot themselves in the foot by setting\n admin_reserve_kbytes too low.\n\n On x86_64, the minimum useful reserve is:\n 8MB for overcommit \u0027guess\u0027\n 128MB for overcommit \u0027never\u0027\n\n admin_reserve_pages defaults to min(3% free memory, 8MB)\n\n So, anyone switching to \u0027never\u0027 mode needs to adjust\n admin_reserve_pages.\n\n * How do you calculate a minimum useful reserve?\n\n A user or the admin needs enough memory to login and perform\n recovery operations, which includes, at a minimum:\n\n sshd or login + bash (or some other shell) + top (or ps, kill, etc.)\n\n For overcommit \u0027guess\u0027, we can sum resident set sizes (RSS)\n because we only need enough memory to handle what the recovery\n programs will typically use. On x86_64 this is about 8MB.\n\n For overcommit \u0027never\u0027, we can take the max of their virtual sizes (VSZ)\n and add the sum of their RSS. We use VSZ instead of RSS because mode\n forces us to ensure we can fulfill all of the requested memory allocations--\n even if the programs only use a fraction of what they ask for.\n On x86_64 this is about 128MB.\n\n When swap is enabled, reserves are useful even when they are as\n small as 10MB, regardless of overcommit mode.\n\n When both swap and overcommit are disabled, then the admin should\n tune the reserves higher to be absolutley safe. Over 230MB each\n was safest in my testing.\n\n * What happens if user_reserve_pages is set to 0?\n\n Note, this only affects overcomitt \u0027never\u0027 mode.\n\n Then a user will be able to allocate all available memory minus\n admin_reserve_kbytes.\n\n However, they will easily see a message such as:\n\n \"bash: fork: Cannot allocate memory\"\n\n And they won\u0027t be able to recover/kill their application.\n The admin should be able to recover the system if\n admin_reserve_kbytes is set appropriately.\n\n * What\u0027s the difference between overcommit \u0027guess\u0027 and \u0027never\u0027?\n\n \"Guess\" allows an allocation if there are enough free + reclaimable\n pages. It has a hardcoded 3% of free pages reserved for root.\n\n \"Never\" allows an allocation if there is enough swap + a configurable\n percentage (default is 50) of physical RAM. It has a hardcoded 3% of\n free pages reserved for root, like \"Guess\" mode. It also has a\n hardcoded 3% of the current process size reserved for additional\n applications.\n\n * Why is overcommit \u0027guess\u0027 not suitable even when an app eventually\n writes to every page? It takes free pages, file pages, available\n swap pages, reclaimable slab pages into consideration. In other words,\n these are all pages available, then why isn\u0027t overcommit suitable?\n\n Because it only looks at the present state of the system. It\n does not take into account the memory that other applications have\n malloced, but haven\u0027t initialized yet. It overcommits the system.\n\nTest Summary\n\nThere was little change in behavior in the default overcommit \u0027guess\u0027\nmode with swap enabled before and after the patch. This was expected.\n\nSystems run most predictably (i.e. no oom kills) in overcommit \u0027never\u0027\nmode with swap enabled. This also allowed the most memory to be allocated\nto a user application.\n\nOvercommit \u0027guess\u0027 mode without swap is a bad idea. It is easy to\ncrash the system. None of the other tested combinations crashed.\nThis matches my experience on the Roadrunner supercomputer.\n\nWithout the tunable user reserve, a system in overcommit \u0027never\u0027 mode\nand without swap does not allow the admin to recover, although the\nadmin can.\n\nWith the new tunable reserves, a system in overcommit \u0027never\u0027 mode\nand without swap can be configured to:\n\n1. maximize user-allocatable memory, running close to the edge of\nrecoverability\n\n2. maximize recoverability, sacrificing allocatable memory to\nensure that a user cannot take down a system\n\nTest Description\n\nFedora 18 VM - 4 x86_64 cores, 5725MB RAM, 4GB Swap\n\nSystem is booted into multiuser console mode, with unnecessary services\nturned off.

I even heard that Google was about to implement it themselves.\n I finally had time and cleaned up the code such that you can now\n create multiple instances of the ftrace buffer and have different\n events go to different buffers. This way, a low frequency event will\n not be lost in the noise of a high frequency event.\n\n Note, currently only events can go to different buffers, the tracers\n (ie function, function_graph and the latency tracers) still can only\n be written to the main buffer.\n\n 2) The function tracer triggers have now been extended.\n\n The function tracer had two triggers. One to enable tracing when a\n function is hit, and one to disable tracing. Now you can record a\n stack trace on a single (or many) function(s), take a snapshot of the\n buffer (copy it to the snapshot buffer), and you can enable or disable\n an event to be traced when a function is hit.\n\n 3) A perf clock has been added.\n\n A \"perf\" clock can be chosen to be used when tracing. This will cause\n ftrace to use the same clock as perf uses, and hopefully this will\n make it easier to interleave the perf and ftrace data for analysis.\"\n\n* tag \u0027trace-3.10\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (82 commits)\n tracepoints: Prevent null probe from being added\n tracing: Compare to 1 instead of zero for is_signed_type()\n tracing: Remove obsolete macro guard _TRACE_PROFILE_INIT\n ftrace: Get rid of ftrace_profile_bits\n tracing: Check return value of tracing_init_dentry()\n tracing: Get rid of unneeded key calculation in ftrace_hash_move()\n tracing: Reset ftrace_graph_filter_enabled if count is zero\n tracing: Fix off-by-one on allocating stat-\u003epages\n kernel: tracing: Use strlcpy instead of strncpy\n tracing: Update debugfs README file\n tracing: Fix ftrace_dump()\n tracing: Rename trace_event_mutex to trace_event_sem\n tracing: Fix comment about prefix in arch_syscall_match_sym_name()\n tracing: Convert trace_destroy_fields() to static\n tracing: Move find_event_field() into trace_events.c\n tracing: Use TRACE_MAX_PRINT instead of constant\n tracing: Use pr_warn_once instead of open coded implementation\n ring-buffer: Add ring buffer startup selftest\n tracing: Bring Documentation/trace/ftrace.txt up to date\n tracing: Add \"perf\" trace_clock\n ...\n\nConflicts:\n\tkernel/trace/ftrace.c\n\tkernel/trace/trace.c\n" }, { "commit": "ec25e246b94a3233ab064994ef05a170bdba0e7c", "tree": "49b7d7e4c46e13bb465c7b832961596e41e8526a", "parents": [ "507ffe4f3840ac24890a8123c702cf1b7fe4d33c", "4626b8daf9bb00ce6b4d533c1a155211ad880f32" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 29 12:19:23 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 29 12:19:23 2013 -0700" }, "message": "Merge tag \u0027usb-3.10-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb\n\nPull USB patches from Greg Kroah-Hartman:\n \"Here\u0027s the big USB pull request for 3.10-rc1.\n\n Lots of USB patches here, the majority being USB gadget changes and\n USB-serial driver cleanups, the rest being ARM build fixes / cleanups,\n and individual driver updates.

consolidation.
