Now it is a\nfunction which calls __local_bh_disable with added irq flags save and\nrestore. The irq flags save and restore were also added to\nlocal_bh_enable, probably for injecting the trace irqs code.\n\nThis overhead is on the generic code path across all architectures. On a\nIA_64 test machine (Itanium-2 1.6 GHz) running a benchmark like netperf\u0027s\nUDP streaming test, the added overhead results in a drop of 3% in\nthroughput, as udp_sendmsg calls the local_bh_enable/disable several times.\n\nOther workloads that have heavy usages of local_bh_enable/disable could\nalso be affected. The patch ideally should not have affected IA-64\nperformance as it does not have IRQ tracing support. A significant portion\nof the overhead is in the added irq flags save and restore, which I think\nis not needed if IRQ tracing is unused.

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.

It \"observes\" and maps all locking rules as\nthey occur dynamically (as triggered by the kernel\u0027s natural use of spinlocks,\nrwlocks, mutexes and rwsems). Whenever the lock validator subsystem detects a\nnew locking scenario, it validates this new rule against the existing set of\nrules. If this new rule is consistent with the existing set of rules then the\nnew rule is added transparently and the kernel continues as normal. If the\nnew rule could create a deadlock scenario then this condition is printed out.\n\nWhen determining validity of locking, all possible \"deadlock scenarios\" are\nconsidered: assuming arbitrary number of CPUs, arbitrary irq context and task\ncontext constellations, running arbitrary combinations of all the existing\nlocking scenarios. In a typical system this means millions of separate\nscenarios. This is why we call it a \"locking correctness\" validator - for all\nrules that are observed the lock validator proves it with mathematical\ncertainty that a deadlock could not occur (assuming that the lock validator\nimplementation itself is correct and its internal data structures are not\ncorrupted by some other kernel subsystem). [see more details and conditionals\nof this statement in include/linux/lockdep.h and\nDocumentation/lockdep-design.txt]\n\nFurthermore, this \"all possible scenarios\" property of the validator also\nenables the finding of complex, highly unlikely multi-CPU multi-context races\nvia single single-context rules, increasing the likelyhood of finding bugs\ndrastically. In practical terms: the lock validator already found a bug in\nthe upstream kernel that could only occur on systems with 3 or more CPUs, and\nwhich needed 3 very unlikely code sequences to occur at once on the 3 CPUs.\nThat bug was found and reported on a single-CPU system (!). So in essence a\nrace will be found \"piecemail-wise\", triggering all the necessary components\nfor the race, without having to reproduce the race scenario itself! In its\nshort existence the lock validator found and reported many bugs before they\nactually caused a real deadlock.\n\nTo further increase the efficiency of the validator, the mapping is not per\n\"lock instance\", but per \"lock-class\". For example, all struct inode objects\nin the kernel have inode-\u003einotify_mutex. If there are 10,000 inodes cached,\nthen there are 10,000 lock objects. But -\u003einotify_mutex is a single \"lock\ntype\", and all locking activities that occur against -\u003einotify_mutex are\n\"unified\" into this single lock-class. The advantage of the lock-class\napproach is that all historical -\u003einotify_mutex uses are mapped into a single\n(and as narrow as possible) set of locking rules - regardless of how many\ndifferent tasks or inode structures it took to build this set of rules. The\nset of rules persist during the lifetime of the kernel.\n\nTo see the rough magnitude of checking that the lock validator does, here\u0027s a\nportion of /proc/lockdep_stats, fresh after bootup:\n\n lock-classes: 694 [max: 2048]\n direct dependencies: 1598 [max: 8192]\n indirect dependencies: 17896\n all direct dependencies: 16206\n dependency chains: 1910 [max: 8192]\n in-hardirq chains: 17\n in-softirq chains: 105\n in-process chains: 1065\n stack-trace entries: 38761 [max: 131072]\n combined max dependencies: 2033928\n hardirq-safe locks: 24\n hardirq-unsafe locks: 176\n softirq-safe locks: 53\n softirq-unsafe locks: 137\n irq-safe locks: 59\n irq-unsafe locks: 176\n\nThe lock validator has observed 1598 actual single-thread locking patterns,\nand has validated all possible 2033928 distinct locking scenarios.\n\nMore details about the design of the lock validator can be found in\nDocumentation/lockdep-design.txt, which can also found at:\n\n http://redhat.com/~mingo/lockdep-patches/lockdep-design.txt\n\n[bunk@stusta.de: cleanups]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "de30a2b355ea85350ca2f58f3b9bf4e5bc007986", "tree": "0bef670aff65614b3c78ca13b20307355b8221d5", "parents": [ "5bdc9b447c0076f494a56fdcd93ee8c5e78a2afd" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jul 03 00:24:42 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 03 15:27:03 2006 -0700" }, "message": "[PATCH] lockdep: irqtrace subsystem, core\n\nAccurate hard-IRQ-flags and softirq-flags state tracing.\n\nThis allows us to attach extra functionality to IRQ flags on/off\nevents (such as trace-on/off).\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "8637c09901049f061b94f684915d4f18ecf91d79", "tree": "83ca3ab38ab4d12f4e10176ba01ae33809388767", "parents": [ "f0a5c315eb266edc608a29971bb4ff1a3025c58f" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jul 03 00:24:38 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 03 15:27:02 2006 -0700" }, "message": "[PATCH] lockdep: stacktrace subsystem, core\n\nFramework to generate and save stacktraces quickly, without printing anything\nto the console.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "e4d919188554a77c798a267e098059bc9aa39726", "tree": "bb5e47e09f5d107db44358ad668988f5ae768ade", "parents": [ "9cebb5526833059f327d237a032422c762378b2a" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jul 03 00:24:34 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 03 15:27:02 2006 -0700" }, "message": "[PATCH] lockdep: locking init debugging improvement\n\nLocking init improvement:\n\n -
