      "message": "tracing: Fix module use of trace_bprintk()\n\nOn use of trace_printk() there\u0027s a macro that determines if the format\nis static or a variable. If it is static, it defaults to __trace_bprintk()\notherwise it uses __trace_printk().\n\nA while ago, Lai Jiangshan added __trace_bprintk(). In that patch, we\ndiscussed a way to allow modules to use it. The difference between\n__trace_bprintk() and __trace_printk() is that for faster processing,\njust the format and args are stored in the trace instead of running\nit through a sprintf function. In order to do this, the format used\nby the __trace_bprintk() had to be persistent.\n\nSee commit 1ba28e02a18cbdbea123836f6c98efb09cbf59ec\n\nThe problem comes with trace_bprintk() where the module is unloaded.\nThe pointer left in the buffer is still pointing to the format.\n\nTo solve this issue, the formats in the module were copied into kernel\ncore. If the same format was used, they would use the same copy (to prevent\nmemory leak). This all worked well until we tried to merge everything.\n\nAt the time this was written, Lai Jiangshan, Frederic Weisbecker,\nIngo Molnar and myself were all touching the same code. When this was\nmerged, we lost the part of it that was in module.c. This kept out the\ncopying of the formats and unloading the module could cause bad pointers\nleft in the ring buffer.\n\nThis patch adds back (with updates required for current kernel) the\nmodule code that sets up the necessary pointers.\n\nCc: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n"

      "message": "perf_events: Fix time tracking in samples\n\nThis patch corrects time tracking in samples. Without this patch\nboth time_enabled and time_running are bogus when user asks for\nPERF_SAMPLE_READ.\n\nOne uses PERF_SAMPLE_READ to sample the values of other counters\nin each sample. Because of multiplexing, it is necessary to know\nboth time_enabled, time_running to be able to scale counts correctly.\n\nIn this second version of the patch, we maintain a shadow\ncopy of ctx-\u003etime which allows us to compute ctx-\u003etime without\ncalling update_context_time() from NMI context. We avoid the\nissue that update_context_time() must always be called with\nctx-\u003elock held.\n\nWe do not keep shadow copies of the other event timings\nbecause if the lead event is overflowing then it is active\nand thus it\u0027s been scheduled in via event_sched_in() in\nwhich case neither tstamp_stopped, tstamp_running can be modified.\n\nThis timing logic only applies to samples when PERF_SAMPLE_READ\nis used.\n\nNote that this patch does not address timing issues related\nto sampling inheritance between tasks. This will be addressed\nin a future patch.\n\nWith this patch, the libpfm4 example task_smpl now reports\ncorrect counts (shown on 2.4GHz Core 2):\n\n$ task_smpl -p 2400000000 -e unhalted_core_cycles:u,instructions_retired:u,baclears  noploop 5\nnoploop for 5 seconds\nIIP:0x000000004006d6 PID:5596 TID:5596 TIME:466,210,211,430 STREAM_ID:33 PERIOD:2,400,000,000 ENA\u003d1,010,157,814 RUN\u003d1,010,157,814 NR\u003d3\n\t2,400,000,254 unhalted_core_cycles:u (33)\n\t2,399,273,744 instructions_retired:u (34)\n\t53,340 baclears (35)\n\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c4cc6e14b.1e07e30a.256e.5190@mx.google.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "posix-cpu-timers: workaround to suppress the problems with mt exec\n\nposix-cpu-timers.c correctly assumes that the dying process does\nposix_cpu_timers_exit_group() and removes all !CPUCLOCK_PERTHREAD\ntimers from signal-\u003ecpu_timers list.\n\nBut, it also assumes that timer-\u003eit.cpu.task is always the group\nleader, and thus the dead -\u003etask means the dead thread group.\n\nThis is obviously not true after de_thread() changes the leader.\nAfter that almost every posix_cpu_timer_ method has problems.\n\nIt is not simple to fix this bug correctly. First of all, I think\nthat timer-\u003eit.cpu should use struct pid instead of task_struct.\nAlso, the locking should be reworked completely. In particular,\ntasklist_lock should not be used at all. This all needs a lot of\nnontrivial and hard-to-test changes.\n\nChange __exit_signal() to do posix_cpu_timers_exit_group() when\nthe old leader dies during exec. This is not the fix, just the\ntemporary hack to hide the problem for 2.6.37 and stable. IOW,\nthis is obviously wrong but this is what we currently have anyway:\ncpu timers do not work after mt exec.\n\nIn theory this change adds another race. The exiting leader can\ndetach the timers which were attached to the new leader. However,\nthe window between de_thread() and release_task() is small, we\ncan pretend that sys_timer_create() was called before de_thread().\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "jump label: Fix module __init section race\n\nJump label uses is_module_text_address() to ensure that the module\n__init sections are valid before updating them. However, between the\ncheck for a valid module __init section and the subsequent jump\nlabel update, the module\u0027s __init section could be freed out from under\nus.\n\nWe fix this potential race by adding a notifier callback to the\nMODULE_STATE_LIVE state. This notifier is called *after* the __init\nsection has been run but before it is going to be freed. In the\ncallback, the jump label code zeros the key value for any __init jump\ncode within the module, and we add a check for a non-zero key value when\nwe update jump labels. In this way we require no additional data\nstructures.\n\nThanks to Mathieu Desnoyers for pointing out this race condition.\n\nReported-by: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nCc: Masami Hiramatsu \u003cmasami.hiramatsu.pt@hitachi.com\u003e\nSigned-off-by: Jason Baron \u003cjbaron@redhat.com\u003e\nLKML-Reference: \u003cc6f037b7598777668025ceedd9294212fd95fa34.1285965957.git.jbaron@redhat.com\u003e\n\n[ Renamed remove_module_init() to remove_jump_label_module_init()\n  as suggested by Masami Hiramatsu. ]\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n"

      "message": "cgroup: add clone_children control file\n\nThe ns_cgroup is a control group interacting with the namespaces.  When a\nnew namespace is created, a corresponding cgroup is automatically created\ntoo.  The cgroup name is the pid of the process who did \u0027unshare\u0027 or the\nchild of \u0027clone\u0027.\n\nThis cgroup is tied with the namespace because it prevents a process to\nescape the control group and use the post_clone callback, so the child\ncgroup inherits the values of the parent cgroup.\n\nUnfortunately, the more we use this cgroup and the more we are facing\nproblems with it:\n\n(1) when a process unshares, the cgroup name may conflict with a\n    previous cgroup with the same pid, so unshare or clone return -EEXIST\n\n(2) the cgroup creation is out of control because there may have an\n    application creating several namespaces where the system will\n    automatically create several cgroups in his back and let them on the\n    cgroupfs (eg.  a vrf based on the network namespace).\n\n(3) the mix of (1) and (2) force an administrator to regularly check\n    and clean these cgroups.\n\nThis patchset removes the ns_cgroup by adding a new flag to the cgroup and\nthe cgroupfs mount option.  It enables the copy of the parent cgroup when\na child cgroup is created.  We can then safely remove the ns_cgroup as\nthis flag brings a compatibility.  We have now to manually create and add\nthe task to a cgroup, which is consistent with the cgroup framework.\n\nThis patch:\n\nSent as an answer to a previous thread around the ns_cgroup.\n\nhttps://lists.linux-foundation.org/pipermail/containers/2009-June/018627.html\n\nIt adds a control file \u0027clone_children\u0027 for a cgroup.  This control file\nis a boolean specifying if the child cgroup should be a clone of the\nparent cgroup or not.  The default value is \u0027false\u0027.\n\nThis flag makes the child cgroup to call the post_clone callback of all\nthe subsystem, if it is available.\n\nAt present, the cpuset is the only one which had implemented the\npost_clone callback.\n\nThe option can be set at mount time by specifying the \u0027clone_children\u0027\nmount option.\n\nSigned-off-by: Daniel Lezcano \u003cdaniel.lezcano@free.fr\u003e\nSigned-off-by: Serge E.

      "message": "debug_core: refactor locking for master/slave cpus\n\nFor quite some time there have been problems with memory barriers and\nvarious races with NMI on multi processor systems using the kernel\ndebugger.  The algorithm for entering the kernel debug core and\nresuming kernel execution was racy and had several known edge case\nproblems with attempting to debug something on a heavily loaded system\nusing breakpoints that are hit repeatedly and quickly.\n\nThe prior \"locking\" design entry worked as follows:\n\n  * The atomic counter kgdb_active was used with atomic exchange in\n    order to elect a master cpu out of all the cpus that may have\n    taken a debug exception.\n  * The master cpu increments all elements of passive_cpu_wait[].\n  * The master cpu issues the round up cpus message.\n  * Each \"slave cpu\" that enters the debug core increments its own\n    element in cpu_in_kgdb[].\n  * Each \"slave cpu\" spins on passive_cpu_wait[] until it becomes 0.\n  * The master cpu debugs the system.\n\nThe new scheme removes the two arrays of atomic counters and replaces\nthem with 2 single counters.  One counter is used to count the number\nof cpus waiting to become a master cpu (because one or more hit an\nexception). The second counter is use to indicate how many cpus have\nentered as slave cpus.\n\nThe new entry logic works as follows:\n\n  * One or more cpus enters via kgdb_handle_exception() and increments\n    the masters_in_kgdb. Each cpu attempts to get the spin lock called\n    dbg_master_lock.\n  * The master cpu sets kgdb_active to the current cpu.\n  * The master cpu takes the spinlock dbg_slave_lock.\n  * The master cpu asks to round up all the other cpus.\n  * Each slave cpu that is not already in kgdb_handle_exception()\n    will enter and increment slaves_in_kgdb.  Each slave will now spin\n    try_locking on dbg_slave_lock.\n  * The master cpu waits for the sum of masters_in_kgdb and slaves_in_kgdb\n    to be equal to the sum of the online cpus.\n  * The master cpu debugs the system.\n\nIn the new design the kgdb_active can only be changed while holding\ndbg_master_lock.  Stress testing has not turned up any further\nentry/exit races that existed in the prior locking design.  The prior\nlocking design suffered from atomic variables not being truly atomic\n(in the capacity as used by kgdb) along with memory barrier races.\n\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\nAcked-by: Dongdong Deng \u003cdongdong.deng@windriver.com\u003e\n"
