      "message": "Make forced module loading optional\n\nThe kernel module loader used to be much too happy to allow loading of\nmodules for the wrong kernel version by default.  For example, if you\nhad MODVERSIONS enabled, but tried to load a module with no version\ninfo, it would happily load it and taint the kernel - whether it was\nlikely to actually work or not!\n\nGenerally, such forced module loading should be considered a really\nreally bad idea, so make it conditional on a new config option\n(MODULE_FORCE_LOAD), and make it default to off.\n\nIf somebody really wants to force module loads, that\u0027s their problem,\nbut we should not encourage it.  Especially as it happened to me by\nmistake (ie regular unversioned Fedora modules getting loaded) causing\nlots of strange behavior.\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "genirq: reenable a nobody cared disabled irq when a new driver arrives\n\nUwe Kleine-Koenig has some strange hardware where one of the shared\ninterrupts can be asserted during boot before the appropriate driver\nloads. Requesting the shared irq line from another driver result in a\nspurious interrupt storm which finally disables the interrupt line.\n\nI have seen similar behaviour on resume before (the hardware does not\nwork anymore so I can not verify).\n\nChange the spurious disable logic to increment the disable depth and\nmark the interrupt with an extra flag which allows us to reenable the\ninterrupt when a new driver arrives which requests the same irq\nline. In the worst case this will disable the irq again via the\nspurious trap, but there is a decent chance that the new driver is the\none which can handle the already asserted interrupt and makes the box\nusable again.\n\nEric Biederman said further: This case also happens on a regular basis\nin kdump kernels where we deliberately don\u0027t shutdown the hardware\nbefore starting the new kernel.  This patch should reduce the need for\nusing irqpoll in that situation by a small amount.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nTested-and-Acked-by: Uwe Kleine-König \u003cUwe.Kleine-Koenig@digi.com\u003e\n\n"

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"

This is correct, but means that check_kill_permission() should\ncall security_task_kill() only for SI_FROMUSER() case, and we can remove the\nsame check from -\u003etask_kill() implementations.\n\n(sadly, check_kill_permission() is the last user of signal-\u003esession/__session\n but we can\u0027t s/task_session_nr/task_session/ here).\n\nNOTE: Eric W.  Biederman pointed out cap_task_kill() should die, and I think\nhe is very right.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: \"Eric W.

      "message": "signals: consolidate send_sigqueue and send_group_sigqueue\n\nBoth functions do the same thing after proper locking, but with\ndifferent sigpending structs, so move the common code into a helper.\n\nAfter this we have 4 places that look very similar: send_sigqueue: calls\ndo_send_sigqueue and signal_wakeup send_group_sigqueue: calls\ndo_send_sigqueue and __group_complete_signal __group_send_sig_info:\ncalls send_signal and __group_complete_signal specific_send_sig_info:\ncalls send_signal and signal_wakeup\n\nBesides, send_signal performs actions similar to do_send_sigqueue\u0027s\nand __group_complete_signal - to signal_wakeup.\n\nIt looks like they can be consolidated gracefully.\n\nOleg said:\n\n  Personally, I think this change is very good.  But send_sigqueue() and\n  send_group_sigqueue() have a very subtle difference which I was never able\n  to understand.\n\n  Let\u0027s suppose that sigqueue is already queued, and the signal is ignored\n  (the latter means we should re-schedule cpu timer or handle overrruns).  In\n  that case send_sigqueue() returns 0, but send_group_sigqueue() returns 1.\n\n  I think this is not the problem (in fact, I think this patch makes the\n  behaviour more correct), but I hope Thomas can take a look and confirm.\n\nSigned-off-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
