      "message": "sched: fix TASK_WAKEKILL vs SIGKILL race\n\nschedule() has the special \"TASK_INTERRUPTIBLE \u0026\u0026 signal_pending()\" case,\nthis allows us to do\n\n\tcurrent-\u003estate \u003d TASK_INTERRUPTIBLE;\n\tschedule();\n\nwithout fear to sleep with pending signal.\n\nHowever, the code like\n\n\tcurrent-\u003estate \u003d TASK_KILLABLE;\n\tschedule();\n\nis not right, schedule() doesn\u0027t take TASK_WAKEKILL into account. This means\nthat mutex_lock_killable(), wait_for_completion_killable(), down_killable(),\nschedule_timeout_killable() can miss SIGKILL (and btw the second SIGKILL has\nno effect).\n\nIntroduce the new helper, signal_pending_state(), and change schedule() to\nuse it. Hopefully it will have more users, that is why the task\u0027s state is\npassed separately.\n\nNote this \"__TASK_STOPPED | __TASK_TRACED\" check in signal_pending_state().\nThis is needed to preserve the current behaviour (ptrace_notify). I hope\nthis check will be removed soon, but this (afaics good) change needs the\nseparate discussion.\n\nThe fast path is \"(state \u0026 (INTERRUPTIBLE | WAKEKILL)) + signal_pending(p)\",\nbasically the same that schedule() does now. However, this patch of course\nbloats schedule().\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

This breaks exec, has other bad implications, and this\n\t  is just wrong.\n\nIntroduce the new SIGNAL_UNKILLABLE flag to fix these problems.

      "message": "signals: re-assign CLD_CONTINUED notification from the sender to reciever\n\nBased on discussion with Jiri and Roland.\n\nIn short: currently handle_stop_signal(SIGCONT, p) sends the notification to\np-\u003eparent, with this patch p itself notifies its parent when it becomes\nrunning.\n\nhandle_stop_signal(SIGCONT) has to drop -\u003esiglock temporary in order to notify\nthe parent with do_notify_parent_cldstop().  This leads to multiple problems:\n\n\t- as Jiri Kosina pointed out, the stopped task can resume without\n\t  actually seeing SIGCONT which may have a handler.\n\n\t- we race with another sig_kernel_stop() signal which may come in\n\t  that window.\n\n\t- we race with sig_fatal() signals which may set SIGNAL_GROUP_EXIT\n\t  in that window.\n\n\t- we can\u0027t avoid taking tasklist_lock() while sending SIGCONT.\n\nWith this patch handle_stop_signal() just sets the new SIGNAL_CLD_CONTINUED\nflag in p-\u003esignal-\u003eflags and returns.  The notification is sent by the first\ntask which returns from finish_stop() (there should be at least one) or any\nother signalled thread from get_signal_to_deliver().\n\nThis is a user-visible change.  Say, currently kill(SIGCONT, stopped_child)\ncan\u0027t return without seeing SIGCHLD, with this patch SIGCHLD can be delayed\nunpredictably.  Another difference is that if the child is ptraced by another\nprocess, CLD_CONTINUED may be delivered to -\u003ereal_parent after ptrace_detach()\nwhile currently it always goes to the tracer which doesn\u0027t actually need this\nnotification.  Hopefully not a problem.\n\nThe patch asks for the futher obvious cleanups, I\u0027ll send them separately.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Jiri Kosina \u003cjkosina@suse.cz\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

The advantage of this approach\nis that, once the mm-\u003eowner is known, using the subsystem id, the cgroup\ncan be determined.  It also allows several control groups that are\nvirtually grouped by mm_struct, to exist independent of the memory\ncontroller i.e., without adding mem_cgroup\u0027s for each controller, to\nmm_struct.\n\nA new config option CONFIG_MM_OWNER is added and the memory resource\ncontroller selects this config option.\n\nThis patch also adds cgroup callbacks to notify subsystems when mm-\u003eowner\nchanges.  The mm_cgroup_changed callback is called with the task_lock() of\nthe new task held and is called just prior to changing the mm-\u003eowner.\n\nI am indebted to Paul Menage for the several reviews of this patchset and\nhelping me make it lighter and simpler.\n\nThis patch was tested on a powerpc box, it was compiled with both the\nMM_OWNER config turned on and off.\n\nAfter the thread group leader exits, it\u0027s moved to init_css_state by\ncgroup_exit(), thus all future charges from runnings threads would be\nredirected to the init_css_set\u0027s subsystem.\n\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nCc: Pavel Emelianov \u003cxemul@openvz.org\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Sudhir Kumar \u003cskumar@linux.vnet.ibm.com\u003e\nCc: YAMAMOTO Takashi \u003cyamamoto@valinux.co.jp\u003e\nCc: Hirokazu Takahashi \u003ctaka@valinux.co.jp\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e,\nCc: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nAcked-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nReviewed-by: Paul Menage \u003cmenage@google.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "capabilities: implement per-process securebits\n\nFilesystem capability support makes it possible to do away with (set)uid-0\nbased privilege and use capabilities instead.  That is, with filesystem\nsupport for capabilities but without this present patch, it is (conceptually)\npossible to manage a system with capabilities alone and never need to obtain\nprivilege via (set)uid-0.\n\nOf course, conceptually isn\u0027t quite the same as currently possible since few\nuser applications, certainly not enough to run a viable system, are currently\nprepared to leverage capabilities to exercise privilege.  Further, many\napplications exist that may never get upgraded in this way, and the kernel\nwill continue to want to support their setuid-0 base privilege needs.\n\nWhere pure-capability applications evolve and replace setuid-0 binaries, it is\ndesirable that there be a mechanisms by which they can contain their\nprivilege.  In addition to leveraging the per-process bounding and inheritable\nsets, this should include suppressing the privilege of the uid-0 superuser\nfrom the process\u0027 tree of children.\n\nThe feature added by this patch can be leveraged to suppress the privilege\nassociated with (set)uid-0.  This suppression requires CAP_SETPCAP to\ninitiate, and only immediately affects the \u0027current\u0027 process (it is inherited\nthrough fork()/exec()).  This reimplementation differs significantly from the\nhistorical support for securebits which was system-wide, unwieldy and which\nhas ultimately withered to a dead relic in the source of the modern kernel.\n\nWith this patch applied a process, that is capable(CAP_SETPCAP), can now drop\nall legacy privilege (through uid\u003d0) for itself and all subsequently\nfork()\u0027d/exec()\u0027d children with:\n\n  prctl(PR_SET_SECUREBITS, 0x2f);\n\nThis patch represents a no-op unless CONFIG_SECURITY_FILE_CAPABILITIES is\nenabled at configure time.\n\n[akpm@linux-foundation.org: fix uninitialised var warning]\n[serue@us.ibm.com: capabilities: use cap_task_prctl when !CONFIG_SECURITY]\nSigned-off-by: Andrew G.

When the tree is deep enough, or the task weight small\n     enough, we\u0027ll run out of bits.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCC: Abhishek Chandra \u003cchandra@cs.umn.edu\u003e\nCC: Srivatsa Vaddagiri \u003cvatsa@linux.vnet.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "capabilities: introduce per-process capability bounding set\n\nThe capability bounding set is a set beyond which capabilities cannot grow.\n Currently cap_bset is per-system.  It can be manipulated through sysctl,\nbut only init can add capabilities.  Root can remove capabilities.  By\ndefault it includes all caps except CAP_SETPCAP.\n\nThis patch makes the bounding set per-process when file capabilities are\nenabled.  It is inherited at fork from parent.  Noone can add elements,\nCAP_SETPCAP is required to remove them.\n\nOne example use of this is to start a safer container.  For instance, until\ndevice namespaces or per-container device whitelists are introduced, it is\nbest to take CAP_MKNOD away from a container.\n\nThe bounding set will not affect pP and pE immediately.

It should address\nDavid Rientjes\u0027s comments, and has been compile tested on all the\narchitectures that it touches, save for parisc.\n\nFor the /proc/\u003cpid\u003e/pagemap code[1], we need to able to query how\nmuch virtual address space a particular task has.  The trick is\nthat we do it through /proc and can\u0027t use TASK_SIZE since it\nreferences \"current\" on some arches.  The process opening the\n/proc file might be a 32-bit process opening a 64-bit process\u0027s\npagemap file.\n\nx86_64 already has a TASK_SIZE_OF() macro:\n\n#define TASK_SIZE_OF(child)     ((test_tsk_thread_flag(child, TIF_IA32)) ? IA32_PAGE_OFFSET : TASK_SIZE64)\n\nI\u0027d like to have that for other architectures.  So, add it\nfor all the architectures that actually use \"current\" in\ntheir TASK_SIZE.  For the others, just add a quick #define\nin sched.h to use plain old TASK_SIZE.\n\n1. http://www.linuxworld.com/news/2007/042407-kernel.html\n\n- MIPS portion from Ralf Baechle \u003cralf@linux-mips.org\u003e\n\n[akpm@linux-foundation.org: fix mips build]\nSigned-off-by: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\nSigned-off-by: Matt Mackall \u003cmpm@selenic.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "sched: add RT-balance cpu-weight\n\nSome RT tasks (particularly kthreads) are bound to one specific CPU.\nIt is fairly common for two or more bound tasks to get queued up at the\nsame time.  Consider, for instance, softirq_timer and softirq_sched.  A\ntimer goes off in an ISR which schedules softirq_thread to run at RT50.\nThen the timer handler determines that it\u0027s time to smp-rebalance the\nsystem so it schedules softirq_sched to run.  So we are in a situation\nwhere we have two RT50 tasks queued, and the system will go into\nrt-overload condition to request other CPUs for help.\n\nThis causes two problems in the current code:\n\n1) If a high-priority bound task and a low-priority unbounded task queue\n   up behind the running task, we will fail to ever relocate the unbounded\n   task because we terminate the search on the first unmovable task.\n\n2) We spend precious futile cycles in the fast-path trying to pull\n   overloaded tasks over.  It is therefore optimial to strive to avoid the\n   overhead all together if we can cheaply detect the condition before\n   overload even occurs.\n\nThis patch tries to achieve this optimization by utilizing the hamming\nweight of the task-\u003ecpus_allowed mask.  A weight of 1 indicates that\nthe task cannot be migrated.  We will then utilize this information to\nskip non-migratable tasks and to eliminate uncessary rebalance attempts.\n\nWe introduce a per-rq variable to count the number of migratable tasks\nthat are currently running.  We only go into overload if we have more\nthan one rt task, AND at least one of them is migratable.\n\nIn addition, we introduce a per-task variable to cache the cpus_allowed\nweight, since the hamming calculation is probably relatively expensive.\nWe only update the cached value when the mask is updated which should be\nrelatively infrequent, especially compared to scheduling frequency\nin the fast path.\n\nSigned-off-by: Gregory Haskins \u003cghaskins@novell.com\u003e\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

Its now calculated as the summation of group weights on a cpu,\nrather than summation of task weights.

If CONFIG_VIRT_CPU_ACCOUNTING is not defined,\nthere is a version of account_process_tick in kernel/timer.c that\nsimply accounts a whole tick to either utime or stime as before.  If\nCONFIG_VIRT_CPU_ACCOUNTING is defined, then arch code gets to\nimplement account_process_tick.\n\nThis also lets us simplify the s390 code a bit; it means that the s390\ntimer interrupt can now call update_process_times even when\nCONFIG_VIRT_CPU_ACCOUNTING is turned on, and can just implement a\nsuitable account_process_tick().\n\naccount_process_tick() now takes the task_struct * as an argument.\nTested both with and without CONFIG_VIRT_CPU_ACCOUNTING.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "cpuset sched_load_balance flag\n\nAdd a new per-cpuset flag called \u0027sched_load_balance\u0027.\n\nWhen enabled in a cpuset (the default value) it tells the kernel scheduler\nthat the scheduler should provide the normal load balancing on the CPUs in\nthat cpuset, sometimes moving tasks from one CPU to a second CPU if the\nsecond CPU is less loaded and if that task is allowed to run there.\n\nWhen disabled (write \"0\" to the file) then it tells the kernel scheduler\nthat load balancing is not required for the CPUs in that cpuset.\n\nNow even if this flag is disabled for some cpuset, the kernel may still\nhave to load balance some or all the CPUs in that cpuset, if some\noverlapping cpuset has its sched_load_balance flag enabled.\n\nIf there are some CPUs that are not in any cpuset whose sched_load_balance\nflag is enabled, the kernel scheduler will not load balance tasks to those\nCPUs.\n\nMoreover the kernel will partition the \u0027sched domains\u0027 (non-overlapping\nsets of CPUs over which load balancing is attempted) into the finest\ngranularity partition that it can find, while still keeping any two CPUs\nthat are in the same shed_load_balance enabled cpuset in the same element\nof the partition.\n\nThis serves two purposes:\n 1) It provides a mechanism for real time isolation of some CPUs, and\n 2) it can be used to improve performance on systems with many CPUs\n    by supporting configurations in which load balancing is not done\n    across all CPUs at once, but rather only done in several smaller\n    disjoint sets of CPUs.\n\nThis mechanism replaces the earlier overloading of the per-cpuset\nflag \u0027cpu_exclusive\u0027, which overloading was removed in an earlier\npatch: cpuset-remove-sched-domain-hooks-from-cpusets\n\nSee further the Documentation and comments in the code itself.\n\n[akpm@linux-foundation.org: don\u0027t be weird]\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
