There is no\nprotection against entries being added to or removed from a chain while the\nchain is in use. The issues were discussed in this thread:\n\n http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113018709002036\u0026w\u003d2\n\nWe noticed that notifier chains in the kernel fall into two basic usage\nclasses:\n\n\t\"Blocking\" chains are always called from a process context\n\tand the callout routines are allowed to sleep;\n\n\t\"Atomic\" chains can be called from an atomic context and\n\tthe callout routines are not allowed to sleep.\n\nWe decided to codify this distinction and make it part of the API. Therefore\nthis set of patches introduces three new, parallel APIs: one for blocking\nnotifiers, one for atomic notifiers, and one for \"raw\" notifiers (which is\nreally just the old API under a new name). New kinds of data structures are\nused for the heads of the chains, and new routines are defined for\nregistration, unregistration, and calling a chain. The three APIs are\nexplained in include/linux/notifier.h and their implementation is in\nkernel/sys.c.\n\nWith atomic and blocking chains, the implementation guarantees that the chain\nlinks will not be corrupted and that chain callers will not get messed up by\nentries being added or removed. For raw chains the implementation provides no\nguarantees at all; users of this API must provide their own protections. (The\nidea was that situations may come up where the assumptions of the atomic and\nblocking APIs are not appropriate, so it should be possible for users to\nhandle these things in their own way.)\n\nThere are some limitations, which should not be too hard to live with. For\natomic/blocking chains, registration and unregistration must always be done in\na process context since the chain is protected by a mutex/rwsem. Also, a\ncallout routine for a non-raw chain must not try to register or unregister\nentries on its own chain. (This did happen in a couple of places and the code\nhad to be changed to avoid it.)\n\nSince atomic chains may be called from within an NMI handler, they cannot use\nspinlocks for synchronization. Instead we use RCU. The overhead falls almost\nentirely in the unregister routine, which is okay since unregistration is much\nless frequent that calling a chain.\n\nHere is the list of chains that we adjusted and their classifications. None\nof them use the raw API, so for the moment it is only a placeholder.\n\n ATOMIC CHAINS\n -------------\narch/i386/kernel/traps.c:\t\ti386die_chain\narch/ia64/kernel/traps.c:\t\tia64die_chain\narch/powerpc/kernel/traps.c:\t\tpowerpc_die_chain\narch/sparc64/kernel/traps.c:\t\tsparc64die_chain\narch/x86_64/kernel/traps.c:\t\tdie_chain\ndrivers/char/ipmi/ipmi_si_intf.c:\txaction_notifier_list\nkernel/panic.c:\t\t\t\tpanic_notifier_list\nkernel/profile.c:\t\t\ttask_free_notifier\nnet/bluetooth/hci_core.c:\t\thci_notifier\nnet/ipv4/netfilter/ip_conntrack_core.c:\tip_conntrack_chain\nnet/ipv4/netfilter/ip_conntrack_core.c:\tip_conntrack_expect_chain\nnet/ipv6/addrconf.c:\t\t\tinet6addr_chain\nnet/netfilter/nf_conntrack_core.c:\tnf_conntrack_chain\nnet/netfilter/nf_conntrack_core.c:\tnf_conntrack_expect_chain\nnet/netlink/af_netlink.c:\t\tnetlink_chain\n\n BLOCKING CHAINS\n ---------------\narch/powerpc/platforms/pseries/reconfig.c:\tpSeries_reconfig_chain\narch/s390/kernel/process.c:\t\tidle_chain\narch/x86_64/kernel/process.c\t\tidle_notifier\ndrivers/base/memory.c:\t\t\tmemory_chain\ndrivers/cpufreq/cpufreq.c\t\tcpufreq_policy_notifier_list\ndrivers/cpufreq/cpufreq.c\t\tcpufreq_transition_notifier_list\ndrivers/macintosh/adb.c:\t\tadb_client_list\ndrivers/macintosh/via-pmu.c\t\tsleep_notifier_list\ndrivers/macintosh/via-pmu68k.c\t\tsleep_notifier_list\ndrivers/macintosh/windfarm_core.c\twf_client_list\ndrivers/usb/core/notify.c\t\tusb_notifier_list\ndrivers/video/fbmem.c\t\t\tfb_notifier_list\nkernel/cpu.c\t\t\t\tcpu_chain\nkernel/module.c\t\t\t\tmodule_notify_list\nkernel/profile.c\t\t\tmunmap_notifier\nkernel/profile.c\t\t\ttask_exit_notifier\nkernel/sys.c\t\t\t\treboot_notifier_list\nnet/core/dev.c\t\t\t\tnetdev_chain\nnet/decnet/dn_dev.c:\t\t\tdnaddr_chain\nnet/ipv4/devinet.c:\t\t\tinetaddr_chain\n\nIt\u0027s possible that some of these classifications are wrong.

Improves efficiency of\nresched_task and some cpu_idle routines.\n\n* In resched_task:\n- TIF_NEED_RESCHED is only cleared with the task\u0027s runqueue lock held,\n and as we hold it during resched_task, then there is no need for an\n atomic test and set there. The only other time this should be set is\n when the task\u0027s quantum expires, in the timer interrupt - this is\n protected against because the rq lock is irq-safe.\n\n- If TIF_NEED_RESCHED is set, then we don\u0027t need to do anything. It\n won\u0027t get unset until the task get\u0027s schedule()d off.\n\n- If we are running on the same CPU as the task we resched, then set\n TIF_NEED_RESCHED and no further action is required.\n\n- If we are running on another CPU, and TIF_POLLING_NRFLAG is *not* set\n after TIF_NEED_RESCHED has been set, then we need to send an IPI.\n\nUsing these rules, we are able to remove the test and set operation in\nresched_task, and make clear the previously vague semantics of\nPOLLING_NRFLAG.\n\n* In idle routines:\n- Enter cpu_idle with preempt disabled. When the need_resched() condition\n becomes true, explicitly call schedule(). This makes things a bit clearer\n (IMO), but haven\u0027t updated all architectures yet.\n\n- Many do a test and clear of TIF_NEED_RESCHED for some reason. According\n to the resched_task rules, this isn\u0027t needed (and actually breaks the\n assumption that TIF_NEED_RESCHED is only cleared with the runqueue lock\n held). So remove that. Generally one less locked memory op when switching\n to the idle thread.\n\n- Many idle routines clear TIF_POLLING_NRFLAG, and only set it in the inner\n most polling idle loops. The above resched_task semantics allow it to be\n set until before the last time need_resched() is checked before going into\n a halt requiring interrupt wakeup.\n\n Many idle routines simply never enter such a halt, and so POLLING_NRFLAG\n can be always left set, completely eliminating resched IPIs when rescheduling\n the idle task.\n\n POLLING_NRFLAG width can be increased, to reduce the chance of resched IPIs.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Con Kolivas \u003ckernel@kolivas.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "5bfb5d690f36d316a5f3b4f7775fda996faa6b12", "tree": "ea53f15293d1ddb49c316eb65df85e939a4f6e5e", "parents": [ "ede3d0fba99520f268067917b50858d788bc41da" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Tue Nov 08 21:39:01 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Nov 09 07:56:33 2005 -0800" }, "message": "[PATCH] sched: disable preempt in idle tasks\n\nRun idle threads with preempt disabled.\n\nAlso corrected a bugs in arm26\u0027s cpu_idle (make it actually call schedule()).\nHow did it ever work before?\n\nMight fix the CPU hotplugging hang which Nigel Cunningham noted.\n\nWe think the bug hits if the idle thread is preempted after checking\nneed_resched() and before going to sleep, then the CPU offlined.\n\nAfter calling stop_machine_run, the CPU eventually returns from preemption and\ninto the idle thread and goes to sleep.
