This type of key cannot be\n created by the user; nor can it be requested by kernel services.\n\n Authorisation keys hold two references:\n\n (a) Each refers to a key being constructed. When the key being\n \t constructed is instantiated the authorisation key is revoked,\n \t rendering it of no further use.\n\n (b) The \"authorising process\". This is either:\n\n \t (i) the process that called request_key(), or:\n\n \t (ii) if the process that called request_key() itself had an\n \t authorisation key in its session keyring, then the authorising\n \t process referred to by that authorisation key will also be\n \t referred to by the new authorisation key.\n\n\t This means that the process that initiated a chain of key requests\n\t will authorise the lot of them, and will, by default, wind up with\n\t the keys obtained from them in its keyrings.\n\n (2) request_key() creates an authorisation key which is then passed to\n /sbin/request-key in as part of a new session keyring.\n\n (3) When request_key() is searching for a key to hand back to the caller, if\n it comes across an authorisation key in the session keyring of the\n calling process, it will also search the keyrings of the process\n specified therein and it will use the specified process\u0027s credentials\n (fsuid, fsgid, groups) to do that rather than the calling process\u0027s\n credentials.\n\n This allows a process started by /sbin/request-key to find keys belonging\n to the authorising process.\n\n (4) A key can be read, even if the process executing KEYCTL_READ doesn\u0027t have\n direct read or search permission if that key is contained within the\n keyrings of a process specified by an authorisation key found within the\n calling process\u0027s session keyring, and is searchable using the\n credentials of the authorising process.\n\n This allows a process started by /sbin/request-key to read keys belonging\n to the authorising process.\n\n (5) The magic KEY_SPEC_*_KEYRING key IDs when passed to KEYCTL_INSTANTIATE or\n KEYCTL_NEGATE will specify a keyring of the authorising process, rather\n than the process doing the instantiation.\n\n (6) One of the process keyrings can be nominated as the default to which\n request_key() should attach new keys if not otherwise specified. This is\n done with KEYCTL_SET_REQKEY_KEYRING and one of the KEY_REQKEY_DEFL_*\n constants. The current setting can also be read using this call.\n\n (7) request_key() is partially interruptible. If it is waiting for another\n process to finish constructing a key, it can be interrupted.

API\n\nTwo new functions are added to kprobes:\n\n\tint register_kretprobe(struct kretprobe *rp);\n\tvoid unregister_kretprobe(struct kretprobe *rp);\n\n2. Registration and unregistration\n\n2.1 Register\n\n To register a function-return probe, the user populates the following\n fields in a kretprobe object and calls register_kretprobe() with the\n kretprobe address as an argument:\n\n kp.addr - the function\u0027s address\n\n handler - this function is run after the ret instruction executes, but\n before control returns to the return address in the caller.\n\n maxactive - The maximum number of instances of the probed function that\n can be active concurrently. For example, if the function is non-\n recursive and is called with a spinlock or mutex held, maxactive \u003d 1\n should be enough. If the function is non-recursive and can never\n relinquish the CPU (e.g., via a semaphore or preemption), NR_CPUS should\n be enough. maxactive is used to determine how many kretprobe_instance\n objects to allocate for this particular probed function. If maxactive \u003c\u003d\n 0, it is set to a default value (if CONFIG_PREEMPT maxactive\u003dmax(10, 2 *\n NR_CPUS) else maxactive\u003dNR_CPUS)\n\n For example:\n\n struct kretprobe rp;\n rp.kp.addr \u003d /* entrypoint address */\n rp.handler \u003d /*return probe handler */\n rp.maxactive \u003d /* e.g., 1 or NR_CPUS or 0, see the above explanation */\n register_kretprobe(\u0026rp);\n\n The following field may also be of interest:\n\n nmissed - Initialized to zero when the function-return probe is\n registered, and incremented every time the probed function is entered but\n there is no kretprobe_instance object available for establishing the\n function-return probe (i.e., because maxactive was set too low).\n\n2.2 Unregister\n\n To unregiter a function-return probe, the user calls\n unregister_kretprobe() with the same kretprobe object as registered\n previously. If a probed function is running when the return probe is\n unregistered, the function will return as expected, but the handler won\u0027t\n be run.\n\n3. Limitations\n\n3.1 This patch supports only the i386 architecture, but patches for\n x86_64 and ppc64 are anticipated soon.\n\n3.2 Return probes operates by replacing the return address in the stack\n (or in a known register, such as the lr register for ppc). This may\n cause __builtin_return_address(0), when invoked from the return-probed\n function, to return the address of the return-probes trampoline.\n\n3.3 This implementation uses the \"Multiprobes at an address\" feature in\n 2.6.12-rc3-mm3.\n\n3.4 Due to a limitation in multi-probes, you cannot currently establish\n a return probe and a jprobe on the same function. A patch to remove\n this limitation is being tested.\n\nThis feature is required by SystemTap (http://sourceware.org/systemtap),\nand reflects ideas contributed by several SystemTap developers, including\nWill Cohen and Ananth Mavinakayanahalli.\n\nSigned-off-by: Hien Nguyen \u003chien@us.ibm.com\u003e\nSigned-off-by: Prasanna S Panchamukhi \u003cprasanna@in.ibm.com\u003e\nSigned-off-by: Frederik Deweerdt \u003cfrederik.deweerdt@laposte.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "df164db5fd16888ddbe2a63a47b2f6dda9a428b5", "tree": "cc9aaf42f93761083e58e1d9d8d22261e0ff3686", "parents": [ "5f45f1a78fbac3cc859ec10c5366e97d20d40fa2" ], "author": { "name": "Alexander Nyberg", "email": "alexn@dsv.su.se", "time": "Thu Jun 23 00:09:13 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:20 2005 -0700" }, "message": "[PATCH] avoid resursive oopses\n\nPrevent recursive faults in do_exit() by leaving the task alone and wait\nfor reboot.

The timer can be fired again after\n del_timer_sync have checked all cpus and before it will recheck\n timer_pending().\n\n2. It has scalability problems. All cpus are scanned to determine\n if the timer is running on that cpu.\n\n With this patch del_timer_sync is O(1) and no slower than plain\n del_timer(pending_timer), unless it has to actually wait for\n completion of the currently running timer.\n\n The only restriction is that the recurring timer should not use\n add_timer_on().\n\n3. The timers are not serialized wrt to itself.\n\n If CPU_0 does mod_timer(jiffies+1) while the timer is currently\n running on CPU 1, it is quite possible that local interrupt on\n CPU_0 will start that timer before it finished on CPU_1.\n\n4. The timers locking is suboptimal. __mod_timer() takes 3 locks\n at once and still requires wmb() in del_timer/run_timers.\n\n The new implementation takes 2 locks sequentially and does not\n need memory barriers.\n\nCurrently -\u003ebase !\u003d NULL means that the timer is pending. In that case\n-\u003ebase.lock is used to lock the timer. __mod_timer also takes timer-\u003elock\nbecause -\u003ebase can be \u003d\u003d NULL.\n\nThis patch uses timer-\u003eentry.next !\u003d NULL as indication that the timer is\npending. So it does __list_del(), entry-\u003enext \u003d NULL instead of list_del()\nwhen the timer is deleted.\n\nThe -\u003ebase field is used for hashed locking only, it is initialized\nin init_timer() which sets -\u003ebase \u003d per_cpu(tvec_bases). When the\ntvec_bases.lock is locked, it means that all timers which are tied\nto this base via timer-\u003ebase are locked, and the base itself is locked\ntoo.\n\nSo __run_timers/migrate_timers can safely modify all timers which could\nbe found on -\u003etvX lists (pending timers).\n\nWhen the timer\u0027s base is locked, and the timer removed from -\u003eentry list\n(which means that _run_timers/migrate_timers can\u0027t see this timer), it is\npossible to set timer-\u003ebase \u003d NULL and drop the lock: the timer remains\nlocked.\n\nThis patch adds lock_timer_base() helper, which waits for -\u003ebase !\u003d NULL,\nlocks the -\u003ebase, and checks it is still the same.\n\n__mod_timer() schedules the timer on the local CPU and changes it\u0027s base.\nHowever, it does not lock both old and new bases at once. It locks the\ntimer via lock_timer_base(), deletes the timer, sets -\u003ebase \u003d NULL, and\nunlocks old base. Then __mod_timer() locks new_base, sets -\u003ebase \u003d new_base,\nand adds this timer. This simplifies the code, because AB-BA deadlock is not\npossible. __mod_timer() also ensures that the timer\u0027s base is not changed\nwhile the timer\u0027s handler is running on the old base.\n\n__run_timers(), del_timer() do not change -\u003ebase anymore, they only clear\npending flag.\n\nSo del_timer_sync() can test timer-\u003ebase-\u003erunning_timer \u003d\u003d timer to detect\nwhether it is running or not.\n\nWe don\u0027t need timer_list-\u003elock anymore, this patch kills it.\n\nWe also don\u0027t need barriers. del_timer() and __run_timers() used smp_wmb()\nbefore clearing timer\u0027s pending flag. It was needed because __mod_timer()\ndid not lock old_base if the timer is not pending, so __mod_timer()-\u003elist_add()\ncould race with del_timer()-\u003elist_del(). With this patch these functions are\nserialized through base-\u003elock.\n\nOne problem. TIMER_INITIALIZER can\u0027t use per_cpu(tvec_bases). So this patch\nadds global\n\n struct timer_base_s {\n spinlock_t lock;\n struct timer_list *running_timer;\n } __init_timer_base;\n\nwhich is used by TIMER_INITIALIZER. The corresponding fields in tvec_t_base_s\nstruct are replaced by struct timer_base_s t_base.\n\nIt is indeed ugly. But this can\u0027t have scalability problems. The global\n__init_timer_base.lock is used only when __mod_timer() is called for the first\ntime AND the timer was compile time initialized. After that the timer migrates\nto the local CPU.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Renaud Lienhart \u003crenaud.lienhart@free.fr\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "59121003721a8fad11ee72e646fd9d3076b5679c", "tree": "c9279c1b74cce81a9dbaf1e7fd038cd55caf26f2", "parents": [ "799d19f6ec5ca2102c61122f5219a17f1c4e961a" ], "author": { "name": "Christoph Lameter", "email": "christoph@lameter.com", "time": "Thu Jun 23 00:08:25 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:10 2005 -0700" }, "message": "[PATCH] i386: Selectable Frequency of the Timer Interrupt\n\nMake the timer frequency selectable.

Before the change new areas were always\n searched from the base address on.\n\n So now new small areas are cluttering holes of all sizes\n throughout the whole mmap-able region whereas before small holes\n tended to close holes near the base leaving holes far from the base\n large and available for larger requests.\n\n 2) the free_area_cache also is set to the location of the last\n munmap-ed area so in scenarios where we allocate e.g. five regions of\n 1K each, then free regions 4 2 3 in this order the next request for 1K\n will be placed in the position of the old region 3, whereas before we\n appended it to the still active region 1, placing it at the location\n of the old region 2.

If a new request comes in the size is compared\nagainst the cached_hole_size and if the request can be filled with a hole\nbelow free_area_cache the search is started from the base instead.\n\nThe results look promising: Whereas 2.6.12-rc4 fragments quickly and my\n(earlier posted) leakme.c test program terminates after 50000+ iterations\nwith 96 distinct and fragmented maps in /proc/self/maps it performs nicely\n(as expected) with thread creation, Ingo\u0027s test_str02 with 20000 threads\nrequires 0.7s system time.\n\nTaking out Ingo\u0027s patch (un-patch available per request) by basically\ndeleting all mentions of free_area_cache from the kernel and starting the\nsearch for new memory always at the respective bases we observe: leakme\nterminates successfully with 11 distinctive hardly fragmented areas in\n/proc/self/maps but thread creating is gringdingly slow: 30+s(!) system\ntime for Ingo\u0027s test_str02 with 20000 threads.\n\nNow - drumroll ;-) the appended patch works fine with leakme: it ends with\nonly 7 distinct areas in /proc/self/maps and also thread creation seems\nsufficiently fast with 0.71s for 20000 threads.\n\nSigned-off-by: Wolfgang Wander \u003cwwc@rentec.com\u003e\nCredit-to: \"Richard Purdie\" \u003crpurdie@rpsys.net\u003e\nSigned-off-by: Ken Chen \u003ckenneth.w.chen@intel.com\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e (partly)\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "753ee728964e5afb80c17659cc6c3a6fd0a42fe0", "tree": "41c9a7700d0858c1f77c5bdaba97e5b636f69b06", "parents": [ "bfbb38fb808ac23ef44472d05d9bb36edfb49ed0" ], "author": { "name": "Martin Hicks", "email": "mort@sgi.com", "time": "Tue Jun 21 17:14:41 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Tue Jun 21 18:46:14 2005 -0700" }, "message": "[PATCH] VM: early zone reclaim\n\nThis is the core of the (much simplified) early reclaim.

In the most common case, this\ncauses a NULL pointer dereference from the routine cpuset_path.\nHowever all manner of bad things are possible, in theory at least.\n\nThe existing code decrements the cpuset use count, and if the\ncount goes to zero, processes the notify_on_release request,\nif appropriate.

The current asynchronous netlink kernel\nmessage processing is vulnerable to these attacks:\n\n1) Hit and run: Attacker sends one or more messages and then exits\nbefore they\u0027re processed. This may confuse/disable the next netlink\nuser that gets the netlink address of the attacker since it may\nreceive the responses to the attacker\u0027s messages.\n\nProposed solutions:\n\na) Synchronous processing.\nb) Stream mode socket.\nc) Restrict/prohibit binding.\n\n2) Starvation: Because various netlink rcv functions were written\nto not return until all messages have been processed on a socket,\nit is possible for these functions to execute for an arbitrarily\nlong period of time. If this is successfully exploited it could\nalso be used to hold rtnl forever.\n\nProposed solutions:\n\na) Synchronous processing.\nb) Stream mode socket.\n\nFirstly let\u0027s cross off solution c). It only solves the first\nproblem and it has user-visible impacts. In particular, it\u0027ll\nbreak user space applications that expect to bind or communicate\nwith specific netlink addresses (pid\u0027s).\n\nSo we\u0027re left with a choice of synchronous processing versus\nSOCK_STREAM for netlink.\n\nFor the moment I\u0027m sticking with the synchronous approach as\nsuggested by Alexey since it\u0027s simpler and I\u0027d rather spend\nmy time working on other things.\n\nHowever, it does have a number of deficiencies compared to the\nstream mode solution:\n\n1) User-space to user-space netlink communication is still vulnerable.\n\n2) Inefficient use of resources. This is especially true for rtnetlink\nsince the lock is shared with other users such as networking drivers.\nThe latter could hold the rtnl while communicating with hardware which\ncauses the rtnetlink user to wait when it could be doing other things.\n\n3) It is still possible to DoS all netlink users by flooding the kernel\nnetlink receive queue. The attacker simply fills the receive socket\nwith a single netlink message that fills up the entire queue. The\nattacker then continues to call sendmsg with the same message in a loop.\n\nPoint 3) can be countered by retransmissions in user-space code, however\nit is pretty messy.\n\nIn light of these problems (in particular, point 3), we should implement\nstream mode netlink at some point. In the mean time, here is a patch\nthat implements synchronous processing. \n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: David S.
