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.

-ENOMEM.\n\nAnd fix whitespace, at least for things I was touching anyway.\n\nSigned-off-by: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nCc: Jeff Dike

It is expected that /sbin/halt -p works exactly like\n/sbin/halt, when the kernel does not implement power off functionality.\n\nThe kernel can do a lot of work in the reboot notifiers and in\ndevice_shutdown before we even get to machine_power_off. Some of that\nshutdown is not safe if you are leaving the power on, and it definitely\ngets in the way of using sysrq or pressing ctrl-alt-del. Since the\nshutdown happens in generic code there is no way to fix this in\narchitecture specific code :(\n\nSome machines are kernel oopsing today because of this.\n\nThe simple solution is to turn LINUX_REBOOT_CMD_POWER_OFF into\nLINUX_REBOOT_CMD_HALT if power_off functionality is not implemented.\n\nThis has the unfortunate side effect of disabling the power off\nfunctionality on architectures that leave pm_power_off to null and still\nimplement something in machine_power_off. And it will break the build on\nsome architectures that don\u0027t have a pm_power_off variable at all.\n\nOn both counts I say tough.\n\nFor architectures like alpha that don\u0027t implement the pm_power_off variable\npm_power_off is declared in linux/pm.h and it is a generic part of our\npower management code, and all architectures should implement it.\n\nFor architectures like parisc that have a default power off method in\nmachine_power_off if pm_power_off is not implemented or fails. It is easy\nenough to set the pm_power_off variable. And nothing bad happens there,\nthe machines just stop powering off.\n\nThe current semantics are impossible without a flag at the top level so we\ncan avoid the problem code if a power off is not implemented. pm_power_off\nis as good a flag as any with the bonus that it works without modification\non at least x86, x86_64, powerpc, and ppc today.\n\nAndrew can you pick this up and put this in the mm tree. Kernels that\ndon\u0027t compile or don\u0027t power off seem saner than kernels that oops or\npanic.

The intent is to make it obvious\nthat an IRQ can\u0027t exist without an open file descriptor.\n\nchan_enable will now open the channel, and when both opening and IRQ\nregistration are desired, this should be used. Opening only is done for the\ninitial console, so that interface still needs to exist.\n\nThe free_irqs_later interface is now gone. It was intended to avoid freeing\nan IRQ while it was being processed. It did this, but it didn\u0027t eliminate the\npossiblity of free_irq being called from an interrupt, which is bad. In its\nplace is a list of irqs to be freed, which is processed by the signal handler\njust before exiting. close_one_chan now disables irqs.\n\nWhen a host device disappears, it is just closed, and that disables IRQs.\n\nThe device id registered with the IRQ is now the chan structure, not the tty.\nThis is because the interrupt arrives on a descriptor associated with the\nchannel. This caused equivalent changes in the arguments to line_timer_cb.\nline_disable is gone since it is not used any more.\n\nThe count field in the line structure is gone. tty-\u003ecount is used instead.\n\nThe complicated logic in sigio_handler with freeing IRQs when necessary and\nmaking sure its idea of the next irq is correct is now much simpler.

While sysrq-t\ndoes the same thing, sysrq-t shows *all* threads stacks. It also doesn\u0027t work\nright now. In the future, I thought it might be acceptable to make this show\nall pids stacks, but perhaps leaving well enough alone and just using sysrq-t\nwould be okay. For now, upon receiving the stack command, UML switches\ncontext to that thread, dumps its registers, and then switches context back to\nthe original thread. Since UML compacts all threads into one of 4 host\nthreads, this sort of mechanism could be expanded in the future to include\nother debugging helpers that sysrq does not cover.\n\nNote by jdike - The main benefit to this is that it brings an arbitrary thread\nback into context, where it can be examined by gdb. The fact that it dumps it\nstack is secondary. This provides the capability to examine a sleeping\nthread, which has existed in tt mode, but not in skas mode until now.\n\nAlso, the other threads, that sysrq doesn\u0027t cover, can be gdb-ed directly\nanyway.\n\nSigned-off-by: Allan Graves\u003callan.graves@gmail.com\u003e\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Paolo Giarrusso \u003cblaisorblade@yahoo.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f6e34c6af6f18bd6c66bfb1c6a7c57068412aa73", "tree": "45aebccc135b870a5aff5dcf975325171c7bf891", "parents": [ "6add9f7f529b124938d14ae9db5a952d1272075a" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Fri Sep 16 19:27:43 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Sep 17 11:49:59 2005 -0700" }, "message": "[PATCH] uml: _switch_to code consolidation\n\nThis patch moves code that is in both switch_to_tt and switch_to_skas to the\ntop level _switch_to function, keeping us from duplicating code.
