Kgdb\nwill use these to manage the capabilities for the 4 hw\nbreakpoint registers, per cpu. Right now the hw_breakpoint API\ndoes not have a way to ask how many breakpoints are available,\non each CPU so it is possible that the install of a breakpoint\nmight fail when kgdb restores the system to the run state. The\nintent of this patch is to first get the basic functionality of\nhw breakpoints working and leave it to the person debugging the\nkernel to understand what hw breakpoints are in use and what\nrestrictions have been imposed as a result. Breakpoint\nconstraints will be dealt with in a future patch.\n\nWhile atomic, the x86 specific kgdb code will call\narch_uninstall_hw_breakpoint() and arch_install_hw_breakpoint()\nto manage the cpu specific hw breakpoints.\n\nThe net result of these changes allow kgdb to use the same pool\nof hw_breakpoints that are used by the perf event API, but\nneither knows about future reservations for the available hw\nbreakpoint slots.\n\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\nAcked-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: kgdb-bugreport@lists.sourceforge.net\nCc: K.Prasad \u003cprasad@linux.vnet.ibm.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: torvalds@linux-foundation.org\nLKML-Reference: \u003c1264719883-7285-2-git-send-email-jason.wessel@windriver.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "b23ff0e9330e4b11e18af984d50573598e10e7f9", "tree": "e170892469ddbcb2ee249271e52264f961c58476", "parents": [ "7f5102ca4b8a8e598dbfa154322ea684bc98da96" ], "author": { "name": "Mahesh Salgaonkar", "email": "mahesh@linux.vnet.ibm.com", "time": "Thu Jan 21 18:25:16 2010 +0530" }, "committer": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Thu Jan 28 14:15:51 2010 +0100" }, "message": "hw_breakpoints: Release the bp slot if arch_validate_hwbkpt_settings() fails.\n\nOn a given architecture, when hardware breakpoint registration fails\ndue to un-supported access type (read/write/execute), we lose the bp\nslot since register_perf_hw_breakpoint() does not release the bp slot\non failure.\nHence, any subsequent hardware breakpoint registration starts failing\nwith \u0027no space left on device\u0027 error.\n\nThis patch introduces error handling in register_perf_hw_breakpoint()\nfunction and releases bp slot on error.\n\nSigned-off-by: Mahesh Salgaonkar \u003cmahesh@linux.vnet.ibm.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nCc: K.

Not resetting the watchdog might result in\nTSC becoming marked unstable, but that\u0027s an acceptable penalty for\nusing kgdb.\n\nThe timekeeping is anyway easily screwed up by kgdb when the system\nuses either jiffies or a clock source which wraps in short intervals\n(e.g. pm_timer wraps about every 4.6s), so we really do not have to\nworry about that occasional TSC marked unstable side effect.\n\nThe second caller of clocksource_resume_watchdog() is\nclocksource_resume().

(but it\u0027s nothing)\n\nB) Current futex code doesn\u0027t handle zero page properly.\n\nRead mode get_user_pages() can return zero page, but current\nfutex code doesn\u0027t handle it at all. Then, zero page makes\ninfinite loop internally.\n\nThe solution is to use write mode get_user_page() always for\npage lookup. It prevents the lookup of both file page of private\nmappings and zero page.\n\nPerformance concerns:\n\nProbaly very little, because glibc always initialize variables\nfor futex before to call futex(). It means glibc users never see\nthe overhead of this patch.\n\nCompatibility concerns:\n\nThis patch has few compatibility issues. After this patch,\nFUTEX_WAIT require writable access to futex variables (read-only\nmappings makes EFAULT). But practically it\u0027s not a problem,\nglibc always initalizes variables for futexes explicitly - nobody\nuses read-only mappings.\n\nReported-by: Hugh Dickins

we\u0027re getting rid of the cgroup, refcount should ensure\n * that there are no pidlists left.\n */\n BUG_ON(!list_empty(\u0026cgrp-\u003epidlists));\n\nThe cgroup pidlist rework in 2.6.32 generates the BUG_ON, which is caused\nwhen pidlist_array_load() calls cgroup_pidlist_find():\n\n(1) if a matching cgroup_pidlist is found, it down_write\u0027s the mutex of the\n pre-existing cgroup_pidlist, and increments its use_count.\n(2) if no matching cgroup_pidlist is found, then a new one is allocated, it\n down_write\u0027s its mutex, and the use_count is set to 0.\n(3) the matching, or new, cgroup_pidlist gets returned back to pidlist_array_load(),\n which increments its use_count -- regardless whether new or pre-existing --\n and up_write\u0027s the mutex.\n\nSo if a matching list is ever encountered by cgroup_pidlist_find() during\nthe life of a cgroup directory, it results in an inflated use_count value,\npreventing it from ever getting released by cgroup_release_pid_array().\nThen if the directory is subsequently removed, cgroup_diput() hits the\nBUG_ON() when it finds that the directory\u0027s cgroup is still populated with\na pidlist.\n\nThe

the list\u0027s mutex.\n\nSigned-off-by: Dave Anderson \u003canderson@redhat.com\u003e\nReviewed-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nAcked-by: Ben Blum \u003cbblum@andrew.cmu.edu\u003e\nCc:

Only 17 files in the current 2.6.31-rc5 used it.\nFIFO\u0027s are like list\u0027s a very basic thing and a kfifo API which handles\nthe most use case would save a lot of development time and memory\nresources.\n\nI think this are the reasons why kfifo is not in use:\n\n - The API is to simple, important functions are missing\n - A fifo can be only allocated dynamically\n - There is a requirement of a spinlock whether you need it or not\n - There is no support for data records inside a fifo\n\nSo I decided to extend the kfifo in a more generic way without blowing up\nthe API to much. The new API has the following benefits:\n\n - Generic usage: For kernel internal use and/or device driver.\n - Provide an API for the most use case.\n - Slim API: The whole API provides 25 functions.\n - Linux style habit.\n - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros\n - Direct copy_to_user from the fifo and copy_from_user into the fifo.\n - The kfifo itself is an in place member of the using data structure, this save an\n indirection access and does not waste the kernel allocator.\n - Lockless access: if only one reader and one writer is active on the fifo,\n which is the common use case, no additional locking is necessary.\n - Remove spinlock - give the user the freedom of choice what kind of locking to use if\n one is required.\n - Ability to handle records. Three type of records are supported:\n - Variable length records between 0-255 bytes, with a record size\n field of 1 bytes.\n - Variable length records between 0-65535 bytes, with a record size\n field of 2 bytes.\n - Fixed size records, which no record size field.\n - Preserve memory resource.\n - Performance!\n - Easy to use!\n\nThis patch:\n\nSince most users want to have the kfifo as part of another object,\nreorganize the code to allow including struct kfifo in another data\nstructure. This requires changing the kfifo_alloc and kfifo_init\nprototypes so that we pass an existing kfifo pointer into them.

Quoting John:\n\n \"Petr Titěra reported an issue where he saw odd atime regressions with\n 2.6.33 where there were a full second worth of nanoseconds in the\n nanoseconds field.\n\n He also reviewed the time code and narrowed down the problem: unhandled\n overflow of the nanosecond field caused by rounding up the\n sub-nanosecond accumulated time.\n\n Details:\n\n * At the end of update_wall_time(), we currently round up the\n sub-nanosecond portion of accumulated time when storing it into xtime.\n This was added to avoid time inconsistencies caused when the\n sub-nanosecond portion was truncated when storing into xtime.\n Unfortunately we don\u0027t handle the possible second overflow caused by\n that rounding.\n\n * Previously the xtime_cache code hid this overflow by normalizing the\n xtime value when storing into the xtime_cache.\n\n * We could try to handle the second overflow after the rounding up, but\n since this affects the timekeeping\u0027s internal state, this would further\n complicate the next accumulation cycle, causing small errors in ntp\n steering. As much as I\u0027d like to get rid of it, the xtime_cache code is\n known to work.\n\n * The correct fix is really to include the sub-nanosecond portion in the\n timekeeping accessor function, so we don\u0027t need to round up at during\n accumulation. This would greatly simplify the accumulation code.\n Unfortunately, we can\u0027t do this safely until the last three\n non-GENERIC_TIME arches (sparc32, arm, cris) are converted (those\n patches are in -mm) and we kill off the spots where arches set xtime\n directly. This is all 2.6.34 material, so I think reverting the\n xtime_cache change is the best approach for now.\n\n Many thanks to Petr for both reporting and finding the issue!\"\n\nReported-by: Petr Titěra \u003cP.Titera@century.cz\u003e\nRequested-by: john stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5300990c0370e804e49d9a59d928c5d53fb73487", "tree": "08ed922afd172662039c082ec9e9410070f4afe8", "parents": [ "482928d59db668b8d82a48717f78986d8cea72e9" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Sat Dec 19 10:15:07 2009 -0500" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Dec 22 12:27:34 2009 -0500" }, "message": "Sanitize f_flags helpers\n\n* pull ACC_MODE to fs.h; we have several copies all over the place\n* nightmarish expression calculating f_mode by f_flags deserves a helper\ntoo (OPEN_FMODE(flags))\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "628ff7c1d8d8466a5ad8078bd0206a130f8b8a51", "tree": "cc7ab0c90849be38e200fc6ff6a3a09e3caf0405", "parents": [ "ed2617585f39dd12fae38c657bba68b9779ea10d" ], "author": { "name": "Roland Dreier", "email": "rdreier@cisco.com", "time": "Fri Dec 18 09:41:24 2009 -0800" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Dec 22 12:27:34 2009 -0500" }, "message": "anonfd: Allow making anon files read-only\n\nIt seems a couple places such as arch/ia64/kernel/perfmon.c and\ndrivers/infiniband/core/uverbs_main.c could use anon_inode_getfile()\ninstead of a private pseudo-fs + alloc_file(), if only there were a way\nto get a read-only file.
