The console semaphore protects the console_drivers list\nthat is used by have_callable_console().\n\nThanks go to Bongani Hlope who saw this as a hang on shutdown and reboot\nand bisected the bug to the right commit, and tested this patch.

The tail/sibling-call\noptimization is not the only way that the compiler can decide to use\nstack argument words as scratch space, which we have to prevent.\nOther optimizations can do it too.\n\nUntil we have new compiler support to make \"asmlinkage\" binding on the\ncompiler\u0027s own use of the stack argument frame, we have work around all\nthe manifestations of this issue that crop up.\n\nMore cases seem to be prevented by also keeping the incoming argument\nvariables live at the end of the function.  This makes their original\nstack slots attractive places to leave those variables, so the compiler\ntends not clobber them for something else.  It\u0027s still no guarantee, but\nit handles some observed cases that prevent_tail_call() did not.\n\nSigned-off-by: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

We use the call_rcu mechanism\nto execute kfree() after such quiescent state has been reached.\nHowever, the new CONFIG_PREEMPT_RCU version of call_rcu and rcu_barrier\ndoes not guarantee that all preempt_disable code regions have finished,\nhence the race.\n\nThe \"proper\" way to do this is to use rcu_read_lock/unlock, but we don\u0027t\nwant to use it to minimize intrusiveness on the traced system.

So a timer can be delayed for quite a long time. This\ntriggered a false positive in the clocksource watchdog code.\n\nTo avoid this we need to wake up the idle CPU and enforce the\nreevaluation of the timer wheel for the next timer event.\n\nAdd a function, which checks a given CPU for idle state, marks the\nidle task with NEED_RESCHED and sends a reschedule IPI to notify the\nother CPU of the change in the timer wheel.\n\nCall this function from add_timer_on().\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: stable@kernel.org\n\n--\n include/linux/sched.h |    6 ++++++\n kernel/sched.c        |   43 +++++++++++++++++++++++++++++++++++++++++++\n kernel/timer.c        |   10 +++++++++-\n 3 files changed, 58 insertions(+), 1 deletion(-)\n\n"

      "message": "audit: netlink socket can be auto-bound to pid other than current-\u003epid (v2)\n\nFrom:\tPavel Emelyanov \u003cxemul@openvz.org\u003e\n\nThis patch is based on the one from Thomas.\n\nThe kauditd_thread() calls the netlink_unicast() and passes \nthe audit_pid to it. The audit_pid, in turn, is received from \nthe user space and the tool (I\u0027ve checked the audit v1.6.9) \nuses getpid() to pass one in the kernel. Besides, this tool \ndoesn\u0027t bind the netlink socket to this id, but simply creates \nit allowing the kernel to auto-bind one.\n\nThat\u0027s the preamble.\n\nThe problem is that netlink_autobind() _does_not_ guarantees\nthat the socket will be auto-bound to the current pid. Instead\nit uses the current pid as a hint to start looking for a free\nid. So, in case of conflict, the audit messages can be sent\nto a wrong socket. This can happen (it\u0027s unlikely, but can be)\nin case some task opens more than one netlink sockets and then\nthe audit one starts - in this case the audit\u0027s pid can be busy\nand its socket will be bound to another id.\n\nThe proposal is to introduce an audit_nlk_pid in audit subsys,\nthat will point to the netlink socket to send packets to. It\nwill most often be equal to audit_pid. The socket id can be \ngot from the skb\u0027s netlink CB right in the audit_receive_msg.\nThe audit_nlk_pid reset to 0 is not required, since all the\ndecisions are taken based on audit_pid value only.\n\nLater, if the audit tools will bind the socket themselves, the\nkernel will have to provide a way to setup the audit_nlk_pid\nas well.\n\nA good side effect of this patch is that audit_pid can later \nbe converted to struct pid, as it is not longer safe to use \npid_t-s in the presence of pid namespaces. But audit code still \nuses the tgid from task_struct in the audit_signal_info and in\nthe audit_filter_syscall.\n\nSigned-off-by: Thomas Graf \u003ctgraf@suug.ch\u003e\nSigned-off-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nAcked-by: Eric Paris \u003ceparis@redhat.com\u003e\nSigned-off-by: David S.

When the\nruntimes are very short because of some server/client ping-pong,\nespecially in over-saturated workloads, this will cycle through all\ntasks trashing the cache.\n\nReduce cache trashing by keeping dependent tasks together by running\nnewly woken tasks first. However, by not running the leftmost task first\nwe could starve tasks because the wakee can gain unlimited runtime.\n\nTherefore we only run the wakee if its within a small\n(wakeup_granularity) window of the leftmost task.

This was caused by the RT balancing code\nthat pulls RT tasks to the current run queue and will reschedule the\ncurrent task.\n\nThere\u0027s a slight chance that the pulling of the RT tasks will release\nthe current runqueue\u0027s lock and retake it (in the double_lock_balance).\nDuring this time that the runqueue is released, the current task can\nmigrate to another runqueue.\n\nIn the prio_changed_rt code, after the pull, if the current task is of\nlesser priority than one of the RT tasks pulled, resched_task is called\non the current task. If the current task had migrated in that small\nwindow, resched_task will be called without holding the runqueue lock\nfor the runqueue that the task is on.\n\nThis race condition also exists in the mainline kernel and this patch\nadds a check to make sure the task hasn\u0027t migrated before calling\nresched_task.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nTested-by: Sripathi Kodi \u003csripathik@in.ibm.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "[RFC] AUDIT: do not panic when printk loses messages\n\nOn the latest kernels if one was to load about 15 rules, set the failure\nstate to panic, and then run service auditd stop the kernel will panic.\nThis is because auditd stops, then the script deletes all of the rules.\nThese deletions are sent as audit messages out of the printk kernel\ninterface which is already known to be lossy.  These will overun the\ndefault kernel rate limiting (10 really fast messages) and will call\naudit_panic().  The same effect can happen if a slew of avc\u0027s come\nthrough while auditd is stopped.\n\nThis can be fixed a number of ways but this patch fixes the problem by\njust not panicing if auditd is not running.  We know printk is lossy and\nif the user chooses to set the failure mode to panic and tries to use\nprintk we can\u0027t make any promises no matter how hard we try, so why try?\nAt least in this way we continue to get lost message accounting and will\neventually know that things went bad.\n\nThe other change is to add a new call to audit_log_lost() if auditd\ndisappears.  We already pulled the skb off the queue and couldn\u0027t send\nit so that message is lost.  At least this way we will account for the\nlast message and panic if the machine is configured to panic.  This code\npath should only be run if auditd dies for unforeseen reasons.  If\nauditd closes correctly audit_pid will get set to 0 and we won\u0027t walk\nthis code path.\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n"

The write that sets CONDITION\ncould move into the critical region protected by the runqueue spinlock.\n\nHowever, adding a smp_wmb() to before the spinlock should now order the\nwriting of CONDITION wrt the lock itself, which in turn is ordered wrt\nthe accesses within the spinlock (which includes the reading of the old\nstate).\n\nThis should thus close the race (which probably has never been seen in\npractice, but since smp_wmb() is a no-op on x86, it\u0027s not like this will\nmake anything worse either on the most common architecture where the\nspinlock already gave the required protection).\n\nAcked-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Dmitry Adamushko \u003cdmitry.adamushko@gmail.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

This is guaranteed to fail, but the call of\nfutex_atomic_cmpxchg_inatomic() happens with pagefaults disabled.\n\nOn architectures, which use the asm-generic implementation or have a runtime\nCPU feature detection, a -ENOSYS return value disables the PI/robust features.\n\nOn architectures with a working implementation the call returns -EFAULT and\nthe PI/robust features are enabled.\n\nThe relevant syscalls return -ENOSYS and the robust list exit code is blocked,\nwhen the detection fails.\n\nFixes http://lkml.org/lkml/2008/2/11/149\nOriginally reported by: Lennart Buytenhek\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Lennert Buytenhek \u003cbuytenh@wantstofly.org\u003e\nCc: Riku Voipio \u003criku.voipio@movial.fi\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
