It can be manipulated through sysctl,\nbut only init can add capabilities. Root can remove capabilities.

It will only\naffect pP\u0027 and pE\u0027 after subsequent exec()s. It also does not affect pI,\nand exec() does not constrain pI\u0027.

mechanism to postpone a cpu-hotplug event as\nlock_cpu_hotplug was badly broken.\n\nThis is another proposal towards solving that problem. This one is along the\nlines of the solution provided in kernel/workqueue.c\n\nInstead of having a global mechanism like lock_cpu_hotplug, we allow the\nsubsytems to define their own per-subsystem hot cpu mutexes. These would be\ntaken(released) where ever we are currently calling\nlock_cpu_hotplug(unlock_cpu_hotplug).\n\nAlso, in the per-subsystem hotcpu callback function,we take this mutex before\nwe handle any pre-cpu-hotplug events and release it once we finish handling\nthe post-cpu-hotplug events. A standard means for doing this has been\nprovided in [PATCH 2/4] and demonstrated in [PATCH 3/4].\n\nThe ordering of these per-subsystem mutexes might still prove to be a\nproblem, but hopefully lockdep should help us get out of that muddle.\n\nThe patch set to be applied against linux-2.6.19-rc5 is as follows:\n\n[PATCH 1/4] :\tExtend notifier_call_chain with an option to specify the\n\t\tnumber of notifications to be sent and also count the\n\t\tnumber of notifications actually sent.\n\n[PATCH 2/4] :\tDefine events CPU_LOCK_ACQUIRE and CPU_LOCK_RELEASE\n\t\tand send out notifications for these in _cpu_up and\n\t\t_cpu_down. This would help us standardise the acquire and\n\t\trelease of the subsystem locks in the hotcpu\n\t\tcallback functions of these subsystems.\n\n[PATCH 3/4] :\tEliminate lock_cpu_hotplug from kernel/sched.c.\n\n[PATCH 4/4] :\tIn workqueue_cpu_callback function, acquire(release) the\n\t\tworkqueue_mutex while handling\n\t\tCPU_LOCK_ACQUIRE(CPU_LOCK_RELEASE).\n\nIf the per-subsystem-locking approach survives the test of time, we can expect\na slow phasing out of lock_cpu_hotplug, which has not yet been eliminated in\nthese patches :)\n\nThis patch:\n\nProvide notifier_call_chain with an option to call only a specified number of\nnotifiers and also record the number of call to notifiers made.\n\nThe need for this enhancement was identified in the post entitled\n\"Slab - Eliminate lock_cpu_hotplug from slab\"\n(http://lkml.org/lkml/2006/10/28/92) by Ravikiran G Thirumalai and\nAndrew Morton.\n\nThis patch adds two additional parameters to notifier_call_chain API namely\n - int nr_to_calls : Number of notifier_functions to be called.\n \t\t The don\u0027t care value is -1.\n\n - unsigned int *nr_calls : Records the total number of notifier_funtions\n\t\t\t called by notifier_call_chain.

Simply moving the check to a\nslightly earlier location (specifically, before the line that actually\nassigns the limit - *old_rlim \u003d new_rlim), does the trick.\n\nDo note that at least the zsh (but not ash, dash, or bash) shell has the\nproblem of \"caching\" the limits set by the ulimit command, so when running\nzsh the fix will not immediately be evident - after entering \"ulimit -t 0\",\n\"ulimit -a\" will show \"-t: cpu time (seconds) 0\", even though the actual\nlimit as returned by getrlimit(...) will be 1. It can be verified by\nopening a subshell (which will not have the values of the parent shell in\ncache) and checking in it, or just by running a CPU intensive command like\n\"echo \u002765536^1048576\u0027 | bc\" and verifying that it dumps core after one\nsecond.\n\nRegardless of whether that is a misfeature in the shell, perhaps it would\nbe better to return -EINVAL from setrlimit in such a case instead of\ncheating and setting to 1, as that does not really reflect the actual state\nof the process anymore.

A local user could create a program that would cause a\ncore file to be dumped into a directory they would not normally have\npermissions to write to. This could lead to a denial of service (disk\nconsumption), or allow the local user to gain root privileges.\n\nThe prctl() system call should never allow to set \"dumpable\" to the\nvalue 2. Especially not for non-privileged users.\n\nThis can be split into three cases:\n\n 1) running as root -- then core dumps will already be done as root,\n and so prctl(PR_SET_DUMPABLE, 2) is not useful\n\n 2) running as non-root w/setuid-to-root -- this is the debatable case\n\n 3) running as non-root w/setuid-to-non-root -- then you definitely\n do NOT want \"dumpable\" to get set to 2 because you have the\n privilege escalation vulnerability\n\nWith case #2, the only potential usefulness is for a program that has\ndesigned to run with higher privilege (than the user invoking it) that\nwants to be able to create root-owned root-validated core dumps. This\nmight be useful as a debugging aid, but would only be safe if the program\nhad done a chdir() to a safe directory.\n\nThere is no benefit to a production setuid-to-root utility, because it\nshouldn\u0027t be dumping core in the first place.

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.

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. Until we get the arch specific patches for the problem\narchitectures this probably isn\u0027t smart to push into the stable kernel.\nUnfortunately I don\u0027t have the time at the moment to walk through every\narchitecture and make them work.
