      "message": "[PATCH] lockdep: allow read_lock() recursion of same class\n\nFrom: Ingo Molnar \u003cmingo@elte.hu\u003e\n\nlockdep so far only allowed read-recursion for the same lock instance.\nThis is enough in the overwhelming majority of cases, but a hostap case\ntriggered and reported by Miles Lane relies on same-class\ndifferent-instance recursion.  So we relax the restriction on read-lock\nrecursion.\n\n(This change does not allow rwsem read-recursion, which is still\nforbidden.)\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] lockdep: core\n\nDo \u0027make oldconfig\u0027 and accept all the defaults for new config options -\nreboot into the kernel and if everything goes well it should boot up fine and\nyou should have /proc/lockdep and /proc/lockdep_stats files.\n\nTypically if the lock validator finds some problem it will print out\nvoluminous debug output that begins with \"BUG: ...\" and which syslog output\ncan be used by kernel developers to figure out the precise locking scenario.\n\nWhat does the lock validator do?  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"

      "message": "[PATCH] lockdep: floppy.c irq release fix\n\nThe lock validator triggered a number of bugs in the floppy driver, all\nrelated to the floppy driver allocating and freeing irq and dma resources from\ninterrupt context.  The initial solution was to use schedule_work() to push\nthis into process context, but this caused further problems: for example the\ncurrent floppy driver in -mm2 is totally broken and all floppy commands time\nout with an error.  (as reported by Barry K.  Nathan)\n\nThis patch tries another solution: simply get rid of all that dynamic IRQ and\nDMA allocation/freeing.  I doubt it made much sense back in the heydays of\nfloppies (if two devices raced for DMA or IRQ resources then we didnt handle\nthose cases too gracefully anyway), and today it makes near zero sense.\n\nSo the new code does the simplest and most straightforward thing: allocate IRQ\nand DMA resources at module init time, and free them at module removal time.\nDont try to release while the driver is operational.  This, besides making the\nfloppy driver functional again has an added bonus, floppy IRQ stats are\nfinally persistent and visible in /proc/interrupts:\n\n  6: 63 XT-PIC-level floppy\n\nBesides normal floppy IO i have also tested IO error handling, motor-off\ntimeouts, etc.  - and everything seems to be working fine.\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"

      "message": "[PATCH] binfmt_elf: fix checks for bad address\n\nFix check for bad address; use macro instead of open-coding two checks.\n\nTaken from RHEL4 kernel update.\n\nFrom: Ernie Petrides \u003cpetrides@redhat.com\u003e\n\n  For background, the BAD_ADDR() macro should return TRUE if the address is\n  TASK_SIZE, because that\u0027s the lowest address that is *not* valid for\n  user-space mappings.  The macro was correct in binfmt_aout.c but was wrong\n  for the \"equal to\" case in binfmt_elf.c.  There were two in-line validations\n  of user-space addresses in binfmt_elf.c, which have been appropriately\n  converted to use the corrected BAD_ADDR() macro in the patch you posted\n  yesterday.  Note that the size checks against TASK_SIZE are okay as coded.\n\n  The additional changes that I propose are below.  These are in the error\n  paths for bad ELF entry addresses once load_elf_binary() has already\n  committed to exec\u0027ing the new image (following the tearing down of the\n  task\u0027s original address space).\n\n  The 1st hunk deals with the interp-side of the outer \"if\".  There were two\n  problems here.  The printk() should be removed because this path can be\n  triggered at will by a bogus interpreter image created and used by a\n  malicious user.  Further, the error code should not be ENOEXEC, because that\n  causes the loop in search_binary_handler() to continue trying other exec\n  handlers (twice, in fact).  But it\u0027s too late for this to work correctly,\n  because the user address space has already been torn down, and an exec()\n  failure cannot be returned to the user code because the code no longer\n  exists.  The only recovery is to force a SIGSEGV, but it\u0027s best to terminate\n  the search loop immediately.  I somewhat arbitrarily chose EINVAL as a\n  fallback error code, but any error returned by load_elf_interp() will\n  override that (but this value will never be seen by user-space).\n\n  The 2nd hunk deals with the non-interp-side of the outer \"if\".  There were\n  two problems here as well.  The SIGSEGV needs to be forced, because a prior\n  sigaction() syscall might have set the associated disposition to SIG_IGN.\n  And the ENOEXEC should be changed to EINVAL as described above.\n\nSigned-off-by: Chuck Ebbert \u003c76306.1226@compuserve.com\u003e\nSigned-off-by: Ernie Petrides \u003cpetrides@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

Zone reclaim may remove 32 unmapped\npages.  File I/O will use these pages for the next read/write requests and the\nunmapped pages increase.  After the zone has filled up again zone reclaim will\nremove it again after only 32 pages.  This cycle is too inefficient and there\nare potentially too many zone reclaim cycles.\n\nWith the 1% boundary we may still remove all unmapped pages for file I/O in\nzone reclaim pass.  However.  it will take a large number of read and writes\nto get back to 1% again where we trigger zone reclaim again.\n\nThe zone reclaim 2.6.16/17 does not show this behavior because we have a 30\nsecond timeout.\n\n[akpm@osdl.org: rename the /proc file and the variable]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
