The autoinstaller feature, for\n example, which determines if your system has a \"good\" version of a\n driver (i.e. if the one provided by DKMS has a newer verson than that\n provided by the kernel package installed), and to automatically compile\n and install a newer version if DKMS has it but your kernel doesn\u0027t yet\n have that version.\n\nb) Because sysadmins manually, or with tools like DKMS, can switch out\n modules on the file system, you can\u0027t count on \u0027modinfo foo.ko\u0027, which\n looks at /lib/modules/${kernelver}/... actually matching what is loaded\n into the kernel already.

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. This permits\n a request-key cycle to be broken without recourse to rebooting.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-Off-By: Benoit Boissinot \u003cbenoit.boissinot@ens-lyon.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "7888e7ff4ee579442128d7d12a9c9dbf2cf7de6a", "tree": "abe428ecb966e1dae07fce17f38e3e0c0ab4f134", "parents": [ "76d8aeabfeb1c42641a81c44280177b9a08670d8" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Jun 23 22:00:51 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Fri Jun 24 00:05:18 2005 -0700" }, "message": "[PATCH] Keys: Pass session keyring to call_usermodehelper()\n\nThe attached patch makes it possible to pass a session keyring through to the\nprocess spawned by call_usermodehelper().

This permits the recursive\n keyring search algorithm to be simplified greatly since no locks need be\n taken other than the usual RCU preemption disablement. Searching now does\n not require any locks or semaphores to be held; merely that the starting\n keyring be pinned.\n\n (4) The keyring payload now includes an RCU head so that it can be disposed\n of by call_rcu(). This requires that the payload be copied on unlink to\n prevent introducing races in copy-down vs search-up.\n\n (5) The user key payload is now a structure with the data following it. It\n includes an RCU head like the keyring payload and for the same reason. It\n also contains a data length because the data length in the key may be\n changed on another CPU whilst an RCU protected read is in progress on the\n payload.

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": "84de856ed30c568c2bb7b9ac0679772bd2737d9b", "tree": "532e4f6bcc0db2d1baf0455484ec7f64a2a51e71", "parents": [ "df164db5fd16888ddbe2a63a47b2f6dda9a428b5" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Thu Jun 23 00:09:16 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:20 2005 -0700" }, "message": "[PATCH] quota: consolidate code surrounding vfs_quota_on_mount\n\nMove some code duplicated in both callers into vfs_quota_on_mount\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nAcked-by: Jan Kara \u003cjack@ucw.cz\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "ac20427ef6aa63da663bdc88b71d16f7394f5e23", "tree": "49ba4f88c5cea42d59b386c508174f585efc8a01", "parents": [ "3bc1ee3e8f1c05c0f64a479c6d56eb34a6190599" ], "author": { "name": "Neil Horman", "email": "nhorman@redhat.com", "time": "Thu Jun 23 00:09:11 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:19 2005 -0700" }, "message": "[PATCH] add check to /proc/devices read routines\n\nPatch to add check to get_chrdev_list and get_blkdev_list to prevent reads\nof /proc/devices from spilling over the provided page if more than 4096\nbytes of string data are generated from all the registered character and\nblock devices in a system\n\nSigned-off-by: Neil Horman \u003cnhorman@redhat.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: \u003cviro@parcelfarce.linux.theplanet.co.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "35a82d1a53e1a9ad54efafcc940f9335beaed5c3", "tree": "776d5b01970c5ce3e2c9fd4a2c4cf2168a0afa3c", "parents": [ "ab4af03a4054bd78bcabfb2214c9597201beae35" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Thu Jun 23 00:09:06 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:18 2005 -0700" }, "message": "[PATCH] optimise loop driver a bit\n\nLooks like locking can be optimised quite a lot.

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": "f7d37d028dfba90b1b747f8ac685bf0959aeda8b", "tree": "38627ec042c05f42feddff2ada95290ebe73679e", "parents": [ "fa72b903f75e4f0f0b2c2feed093005167da4023" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Thu Jun 23 00:08:50 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:15 2005 -0700" }, "message": "[PATCH] blk: remove BLK_TAGS_{PER_LONG|MASK}\n\nReplace BLK_TAGS_PER_LONG with BITS_PER_LONG and remove unused BLK_TAGS_MASK.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nAcked-by: Jens Axboe \u003caxboe@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "fa72b903f75e4f0f0b2c2feed093005167da4023", "tree": "12087e87fb8d41d10013946e5b2c91e57265c29e", "parents": [ "2bf0fdad51c6710bf15d0bf4b9b30b8498fe4ddd" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Thu Jun 23 00:08:49 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:15 2005 -0700" }, "message": "[PATCH] blk: remove blk_queue_tag-\u003ereal_max_depth optimization\n\nblk_queue_tag-\u003ereal_max_depth was used to optimize out unnecessary\nallocations/frees on tag resize.
