It calls\nthe get_block() callback with \"create \u003d 1\" and if that succeeds it\nimmediately clears buffer_new on the just allocated buffer (which has\nbuffer_new set).\n\nThe bug is that if an error occurs and get_block() returns !\u003d 0, we break\nfrom this loop and go into recovery code. This code has this comment:\n\n/* Error case: */\n/*\n * Zero out any newly allocated blocks to avoid exposing stale\n * data. If BH_New is set, we know that the block was newly\n * allocated in the above loop.\n */\n\nSo the intent is obviously good in that it wants to clear just allocated\nand hence not zeroed buffers. However the code recognises allocated\nbuffers by checking for buffer_new being set.\n\nUnfortunately __block_prepare_write() as discussed above already cleared\nbuffer_new on all allocated buffers thus no buffers will be cleared during\nerror recovery and old data will be leaked.\n\nThe simplest way I can see to fix this is to make the current recovery code\nwork by _not_ clearing buffer_new after calling get_block() in\n__block_prepare_write().\n\nWe cannot safely allow buffer_new buffers to \"leak out\" of\n__block_prepare_write(), thus we simply do a quick loop over the buffers\nclearing buffer_new on each of them if it is set just before returning\n\"success\" from __block_prepare_write().\n\nSigned-off-by: Anton Altaparmakov \u003caia21@cantab.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9a59f452abe11f569e13ec16c51e6d61c54b9838", "tree": "0fc242afbf51aac7214e3a9b7620e83d0d4016f2", "parents": [ "f9fd27a253d5e0b23531d12ce7ad15b6535d4486" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Thu Jun 23 00:10:19 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:33 2005 -0700" }, "message": "[PATCH] remove \u003clinux/xattr_acl.h\u003e\n\nThis file duplicates \u003clinux/posix_acl_xattr.h\u003e, using slightly different\nnames.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f9fd27a253d5e0b23531d12ce7ad15b6535d4486", "tree": "1ff92c3b1ec8c707f71154313ce98e73423b6d54", "parents": [ "30aaa80885df5d1518d498a450e73282cea8d8b1" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Thu Jun 23 00:10:19 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:33 2005 -0700" }, "message": "[PATCH] acl endianess annotations\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "30aaa80885df5d1518d498a450e73282cea8d8b1", "tree": "7f001c8339bd9ed972bc570b78a800852cf4e4fa", "parents": [ "45778ca819accab1a4a3378b3566cab0f189164f" ], "author": { "name": "William Lee Irwin III", "email": "wli@holomorphy.com", "time": "Thu Jun 23 00:10:18 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:33 2005 -0700" }, "message": "[PATCH] use drivers/Kconfig for sparc32\n\nKconfig is spitting out massive numbers of errors and so on.

This has the\nadded advantage that it works for any callers of ext3_find_entry() and not\njust ext3_lookup_parent().\n\nSigned-off-by: Andreas Dilger \u003cadilger@clusterfs.com\u003e\nSigned-off-by: Henrik Grubbstrom \u003cgrubba@grubba.org\u003e\nCc: \u003cext2-devel@lists.sourceforge.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d6e711448137ca3301512cec41a2c2ce852b3d0a", "tree": "f0765ebd90fdbdf270c05fcd7f3d32b24ba56681", "parents": [ "8b0914ea7475615c7c8965c1ac8fe4069270f25c" ], "author": { "name": "Alan Cox", "email": "alan@lxorguk.ukuu.org.uk", "time": "Thu Jun 23 00:09:43 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:26 2005 -0700" }, "message": "[PATCH] setuid core dump\n\nAdd a new `suid_dumpable\u0027 sysctl:\n\nThis value can be used to query and set the core dump mode for setuid\nor otherwise protected/tainted binaries.

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).

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": "bdd646a44672115c986593956aa4ef105485a184", "tree": "705b347a9c84fe7dcc040b468cadf28bde332bcf", "parents": [ "fde6ad22480cdc2eaa102b805a3ed3ee1d36a376" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Thu Jun 23 00:08:54 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:16 2005 -0700" }, "message": "[PATCH] blk: unplug later\n\nget_request_wait needn\u0027t unplug the device immediately.\n\nSigned-off-by: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: 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": "fde6ad22480cdc2eaa102b805a3ed3ee1d36a376", "tree": "17489dacb9dcd2fd16d6bd0137098d85520e59b7", "parents": [ "250dccc00805e755a6d80a73557034253da0831f" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Thu Jun 23 00:08:53 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:16 2005 -0700" }, "message": "[PATCH] blk: branch hints\n\nSprinkle around a few branch hints in the block layer.\n\nSigned-off-by: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: 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": "250dccc00805e755a6d80a73557034253da0831f", "tree": "da9f94abed8dac7479507601694d9276b2dbaf28", "parents": [ "040c928c47b591d1cd9977cd6431cae213528b45" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Thu Jun 23 00:08:52 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:16 2005 -0700" }, "message": "[PATCH] blk: no memory barrier\n\nThis memory barrier is not needed because the waitqueue will only get waiters\non it in the following situations:\n\nrq-\u003ecount has exceeded the threshold - however all manipulations of -\u003ecount\nare performed under the runqueue lock, and so we will correctly pick up any\nwaiter.\n\nMemory allocation for the request fails.

It is expected that each pin can potentually be\nengaged by a device inserted into the corresponding PCI slot. However,\nthis imposes severe limitation on systems that have designs that employ\nmany I/O APICs, only utilizing couple lines of each, such as P64H2 chipset.\n\nIt is used in ES7000, and currently, there is no way to boot the system\nwith more that 9 I/O APICs.\n\nThe simple change below allows to boot a system with say 64 (or more) I/O\nAPICs, each providing 1 slot, which otherwise impossible because of the IRQ\ngaps created for unused lines on each I/O APIC. It does not resolve the\nproblem with number of devices that exceeds number of possible IRQs, but\neases up a tension for IRQs on any large system with potentually large\nnumber of devices.\n\nI only implemented this for the ACPI boot, since if the system is this big\nand using newer chipsets it is probably (better be!) an ACPI based system\n:). The change is completely \"mechanical\" and does not alter any internal\nstructures or interrupt model/implementation. The patch works for both\ni386 and x86_64 archs. It works with MSIs just fine, and should not\nintervene with implementations like shared vectors, when they get worked\nout and incorporated.\n\nTo illustrate, below is the interrupt distribution for 2-cell ES7000 with\n20 I/O APICs, and an Ethernet card in the last slot, which should be eth1\nand which was not configured because its IRQ exceeded allowable number (it\nactially turned out huge - 480!):\n\nzorro-tb2:~ # cat /proc/interrupts\n CPU0 CPU1 CPU2 CPU3 CPU4 CPU5 CPU6 CPU7\n 0: 65716 30012 30007 30002 30009 30010 30010 30010 IO-APIC-edge timer\n 4: 373 0 725 280 0 0 0 0 IO-APIC-edge serial\n 8: 0 0 0 0 0 0 0 0 IO-APIC-edge rtc\n 9: 0 0 0 0 0 0 0 0 IO-APIC-level acpi\n 14: 39 3 0 0 0 0 0 0 IO-APIC-edge ide0\n 16: 108 13 0 0 0 0 0 0 IO-APIC-level uhci_hcd:usb1\n 18: 0 0 0 0 0 0 0 0 IO-APIC-level uhci_hcd:usb3\n 19: 15 0 0 0 0 0 0 0 IO-APIC-level uhci_hcd:usb2\n 23: 3 0 0 0 0 0 0 0 IO-APIC-level ehci_hcd:usb4\n 96: 4240 397 18 0 0 0 0 0 IO-APIC-level aic7xxx\n 97: 15 0 0 0 0 0 0 0 IO-APIC-level aic7xxx\n192: 847 0 0 0 0 0 0 0 IO-APIC-level eth0\nNMI: 0 0 0 0 0 0 0 0\nLOC: 273423 274528 272829 274228 274092 273761 273827 273694\nERR: 7\nMIS: 0\n\nEven though the system doesn\u0027t have that many devices, some don\u0027t get\nenabled only because of IRQ numbering model.\n\nThis is the IRQ picture after the patch was applied:\n\nzorro-tb2:~ # cat /proc/interrupts\n CPU0 CPU1 CPU2 CPU3 CPU4 CPU5 CPU6 CPU7\n 0: 44169 10004 10004 10001 10004 10003 10004 6135 IO-APIC-edge timer\n 4: 345 0 0 0 0 244 0 0 IO-APIC-edge serial\n 8: 0 0 0 0 0 0 0 0 IO-APIC-edge rtc\n 9: 0 0 0 0 0 0 0 0 IO-APIC-level acpi\n 14: 39 0 3 0 0 0 0 0 IO-APIC-edge ide0\n 17: 4425 0 9 0 0 0 0 0 IO-APIC-level aic7xxx\n 18: 15 0 0 0 0 0 0 0 IO-APIC-level aic7xxx, uhci_hcd:usb3\n 21: 231 0 0 0 0 0 0 0 IO-APIC-level uhci_hcd:usb1\n 22: 26 0 0 0 0 0 0 0 IO-APIC-level uhci_hcd:usb2\n 23: 3 0 0 0 0 0 0 0 IO-APIC-level ehci_hcd:usb4\n 24: 348 0 0 0 0 0 0 0 IO-APIC-level eth0\n 25: 6 192 0 0 0 0 0 0 IO-APIC-level eth1\nNMI: 0 0 0 0 0 0 0 0\nLOC: 107981 107636 108899 108698 108489 108326 108331 108254\nERR: 7\nMIS: 0\n\nNot only we see the card in the last I/O APIC, but we are not even close to\nusing up available IRQs, since we didn\u0027t waste any.\n\nSigned-off-by: Natalie Protasevich \u003cNatalie.Protasevich@unisys.com\u003e\nAcked-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "32ecd42b6f94d3ee320a22827b46bd19ccf924e5", "tree": "ea74d38338f800940e630d075ca157149871f37d", "parents": [ "0928d6ef7f204979749fb241a90a04a35dae133a" ], "author": { "name": "Jan Beulich", "email": "JBeulich@novell.com", "time": "Thu Jun 23 00:08:38 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:13 2005 -0700" }, "message": "[PATCH] eliminate duplicate rdpmc definition\n\nEliminate duplicate definition of rdpmc in x86-64\u0027s mtrr.h.\n\nSigned-off-by: Jan Beulich \u003cjbeulich@novell.com\u003e\nCc: Andi Kleen \u003cak@muc.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0928d6ef7f204979749fb241a90a04a35dae133a", "tree": "f91a3a4725a2e59ed3cfce4cabd31f61798b9342", "parents": [ "a3a00751ad8970c13d0563c2e92ee68c655a8e6b" ], "author": { "name": "Roland McGrath", "email": "roland@redhat.com", "time": "Thu Jun 23 00:08:37 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:13 2005 -0700" }, "message": "[PATCH] x86_64: never block forced SIGSEGV\n\nThis is the x86_64 version of the signal fix I just posted for i386.\n\nThis problem was first noticed on PPC and has already been fixed there.\nBut the exact same issue applies to other platforms in the same way.
