      "message": "\"Tree RCU\": scalable classic RCU implementation\n\nThis patch fixes a long-standing performance bug in classic RCU that\nresults in massive internal-to-RCU lock contention on systems with\nmore than a few hundred CPUs.  Although this patch creates a separate\nflavor of RCU for ease of review and patch maintenance, it is intended\nto replace classic RCU.\n\nThis patch still handles stress better than does mainline, so I am still\ncalling it ready for inclusion.  This patch is against the -tip tree.\nNevertheless, experience on an actual 1000+ CPU machine would still be\nmost welcome.\n\nMost of the changes noted below were found while creating an rcutiny\n(which should permit ejecting the current rcuclassic) and while doing\ndetailed line-by-line documentation.\n\nUpdates from v9 (http://lkml.org/lkml/2008/12/2/334):\n\no\tFixes from remainder of line-by-line code walkthrough,\n\tincluding comment spelling, initialization, undesirable\n\tnarrowing due to type conversion, removing redundant memory\n\tbarriers, removing redundant local-variable initialization,\n\tand removing redundant local variables.\n\n\tI do not believe that any of these fixes address the CPU-hotplug\n\tissues that Andi Kleen was seeing, but please do give it a whirl\n\tin case the machine is smarter than I am.\n\n\tA writeup from the walkthrough may be found at the following\n\tURL, in case you are suffering from terminal insomnia or\n\tmasochism:\n\n\thttp://www.kernel.org/pub/linux/kernel/people/paulmck/tmp/rcutree-walkthrough.2008.12.16a.pdf\n\no\tMade rcutree tracing use seq_file, as suggested some time\n\tago by Lai Jiangshan.\n\no\tAdded a .csv variant of the rcudata debugfs trace file, to allow\n\tpeople having thousands of CPUs to drop the data into\n\ta spreadsheet.\tTested with oocalc and gnumeric.  Updated\n\tdocumentation to suit.\n\nUpdates from v8 (http://lkml.org/lkml/2008/11/15/139):\n\no\tFix a theoretical race between grace-period initialization and\n\tforce_quiescent_state() that could occur if more than three\n\tjiffies were required to carry out the grace-period\n\tinitialization.  Which it might, if you had enough CPUs.\n\no\tApply Ingo\u0027s printk-standardization patch.\n\no\tSubstitute local variables for repeated accesses to global\n\tvariables.\n\no\tFix comment misspellings and redundant (but harmless) increments\n\tof -\u003en_rcu_pending (this latter after having explicitly added it).\n\no\tApply checkpatch fixes.\n\nUpdates from v7 (http://lkml.org/lkml/2008/10/10/291):\n\no\tFixed a number of problems noted by Gautham Shenoy, including\n\tthe cpu-stall-detection bug that he was having difficulty\n\tconvincing me was real.  ;-)\n\no\tChanged cpu-stall detection to wait for ten seconds rather than\n\tthree in order to reduce false positive, as suggested by Ingo\n\tMolnar.\n\no\tProduced a design document (http://lwn.net/Articles/305782/).\n\tThe act of writing this document uncovered a number of both\n\ttheoretical and \"here and now\" bugs as noted below.\n\no\tFix dynticks_nesting accounting confusion, simplify WARN_ON()\n\tcondition, fix kerneldoc comments, and add memory barriers\n\tin dynticks interface functions.\n\no\tAdd more data to tracing.\n\no\tRemove unused \"rcu_barrier\" field from rcu_data structure.\n\no\tCount calls to rcu_pending() from scheduling-clock interrupt\n\tto use as a surrogate timebase should jiffies stop counting.\n\no\tFix a theoretical race between force_quiescent_state() and\n\tgrace-period initialization.  Yes, initialization does have to\n\tgo on for some jiffies for this race to occur, but given enough\n\tCPUs...\n\nUpdates from v6 (http://lkml.org/lkml/2008/9/23/448):\n\no\tFix a number of checkpatch.pl complaints.\n\no\tApply review comments from Ingo Molnar and Lai Jiangshan\n\ton the stall-detection code.\n\no\tFix several bugs in !CONFIG_SMP builds.\n\no\tFix a misspelled config-parameter name so that RCU now announces\n\tat boot time if stall detection is configured.\n\no\tRun tests on numerous combinations of configurations parameters,\n\twhich after the fixes above, now build and run correctly.\n\nUpdates from v5 (http://lkml.org/lkml/2008/9/15/92, bad subject line):\n\no\tFix a compiler error in the !CONFIG_FANOUT_EXACT case (blew a\n\tchangeset some time ago, and finally got around to retesting\n\tthis option).\n\no\tFix some tracing bugs in rcupreempt that caused incorrect\n\ttotals to be printed.\n\no\tI now test with a more brutal random-selection online/offline\n\tscript (attached).  Probably more brutal than it needs to be\n\ton the people reading it as well, but so it goes.\n\no\tA number of optimizations and usability improvements:\n\n\to\tMake rcu_pending() ignore the grace-period timeout when\n\t\tthere is no grace period in progress.\n\n\to\tMake force_quiescent_state() avoid going for a global\n\t\tlock in the case where there is no grace period in\n\t\tprogress.\n\n\to\tRearrange struct fields to improve struct layout.\n\n\to\tMake call_rcu() initiate a grace period if RCU was\n\t\tidle, rather than waiting for the next scheduling\n\t\tclock interrupt.\n\n\to\tInvoke rcu_irq_enter() and rcu_irq_exit() only when\n\t\tidle, as suggested by Andi Kleen.  I still don\u0027t\n\t\tcompletely trust this change, and might back it out.\n\n\to\tMake CONFIG_RCU_TRACE be the single config variable\n\t\tmanipulated for all forms of RCU, instead of the prior\n\t\tconfusion.\n\n\to\tDocument tracing files and formats for both rcupreempt\n\t\tand rcutree.\n\nUpdates from v4 for those missing v5 given its bad subject line:\n\no\tSeparated dynticks interface so that NMIs and irqs call separate\n\tfunctions, greatly simplifying it.  In particular, this code\n\tno longer requires a proof of correctness.  ;-)\n\no\tSeparated dynticks state out into its own per-CPU structure,\n\tavoiding the duplicated accounting.\n\no\tThe case where a dynticks-idle CPU runs an irq handler that\n\tinvokes call_rcu() is now correctly handled, forcing that CPU\n\tout of dynticks-idle mode.\n\no\tReview comments have been applied (thank you all!!!).\n\tFor but one example, fixed the dynticks-ordering issue that\n\tManfred pointed out, saving me much debugging.  ;-)\n\no\tAdjusted rcuclassic and rcupreempt to handle dynticks changes.\n\nAttached is an updated patch to Classic RCU that applies a hierarchy,\ngreatly reducing the contention on the top-level lock for large machines.\nThis passes 10-hour concurrent rcutorture and online-offline testing on\n128-CPU ppc64 without dynticks enabled, and exposes some timekeeping\nbugs in presence of dynticks (exciting working on a system where\n\"sleep 1\" hangs until interrupted...), which were fixed in the\n2.6.27 kernel.  It is getting more reliable than mainline by some\nmeasures, so the next version will be against -tip for inclusion.\nSee also Manfred Spraul\u0027s recent patches (or his earlier work from\n2004 at http://marc.info/?l\u003dlinux-kernel\u0026m\u003d108546384711797\u0026w\u003d2).\nWe will converge onto a common patch in the fullness of time, but are\ncurrently exploring different regions of the design space.  That said,\nI have already gratefully stolen quite a few of Manfred\u0027s ideas.\n\nThis patch provides CONFIG_RCU_FANOUT, which controls the bushiness\nof the RCU hierarchy.  Defaults to 32 on 32-bit machines and 64 on\n64-bit machines.  If CONFIG_NR_CPUS is less than CONFIG_RCU_FANOUT,\nthere is no hierarchy.  By default, the RCU initialization code will\nadjust CONFIG_RCU_FANOUT to balance the hierarchy, so strongly NUMA\narchitectures may choose to set CONFIG_RCU_FANOUT_EXACT to disable\nthis balancing, allowing the hierarchy to be exactly aligned to the\nunderlying hardware.  Up to two levels of hierarchy are permitted\n(in addition to the root node), allowing up to 16,384 CPUs on 32-bit\nsystems and up to 262,144 CPUs on 64-bit systems.  I just know that I\nam going to regret saying this, but this seems more than sufficient\nfor the foreseeable future.  (Some architectures might wish to set\nCONFIG_RCU_FANOUT\u003d4, which would limit such architectures to 64 CPUs.\nIf this becomes a real problem, additional levels can be added, but I\ndoubt that it will make a significant difference on real hardware.)\n\nIn the common case, a given CPU will manipulate its private rcu_data\nstructure and the rcu_node structure that it shares with its immediate\nneighbors.  This can reduce both lock and memory contention by multiple\norders of magnitude, which should eliminate the need for the strange\nmanipulations that are reported to be required when running Linux on\nvery large systems.\n\nSome shortcomings:\n\no\tMore bugs will probably surface as a result of an ongoing\n\tline-by-line code inspection.\n\n\tPatches will be provided as required.\n\no\tThere are probably hangs, rcutorture failures, \u0026c.  Seems\n\tquite stable on a 128-CPU machine, but that is kind of small\n\tcompared to 4096 CPUs.  However, seems to do better than\n\tmainline.\n\n\tPatches will be provided as required.\n\no\tThe memory footprint of this version is several KB larger\n\tthan rcuclassic.\n\n\tA separate UP-only rcutiny patch will be provided, which will\n\treduce the memory footprint significantly, even compared\n\tto the old rcuclassic.  One such patch passes light testing,\n\tand has a memory footprint smaller even than rcuclassic.\n\tInitial reaction from various embedded guys was \"it is not\n\tworth it\", so am putting it aside.\n\nCredits:\n\no\tManfred Spraul for ideas, review comments, and bugs spotted,\n\tas well as some good friendly competition.  ;-)\n\no\tJosh Triplett, Ingo Molnar, Peter Zijlstra, Mathieu Desnoyers,\n\tLai Jiangshan, Andi Kleen, Andy Whitcroft, and Andrew Morton\n\tfor reviews and comments.\n\no\tThomas Gleixner for much-needed help with some timer issues\n\t(see patches below).\n\no\tJon M.

It zeroes out counters on \"other\" cpus,\nwithout holding any locks which will prevent races agaist updates from\nthose other CPUS.\n\nThis patch reverts 1f7c14c62ce63805f9574664a6c6de3633d4a354.  This means\nthat percpu_counter_sum_and_set() still has the race, but\npercpu_counter_sum() does not.\n\nNote that this is not a simple revert - ext4 has since started using\npercpu_counter_sum() for its dirty_blocks counter as well.\n\nNote that this revert patch changes percpu_counter_sum() semantics.\n\nBefore the patch, a call to percpu_counter_sum() will bring the counter\u0027s\ncentral counter mostly up-to-date, so a following percpu_counter_read()\nwill return a close value.\n\nAfter this patch, a call to percpu_counter_sum() will leave the counter\u0027s\ncentral accumulator unaltered, so a subsequent call to\npercpu_counter_read() can now return a significantly inaccurate result.\n\nIf there is any code in the tree which was introduced after\ne8ced39d5e8911c662d4d69a342b9d053eaaac4e was merged, and which depends\nupon the new percpu_counter_sum() semantics, that code will break.\n\nReported-by: Eric Dumazet \u003cdada1@cosmosbay.com\u003e\nCc: \"David S.

      "message": "CRED: Inaugurate COW credentials\n\nInaugurate copy-on-write credentials management.  This uses RCU to manage the\ncredentials pointer in the task_struct with respect to accesses by other tasks.\nA process may only modify its own credentials, and so does not need locking to\naccess or modify its own credentials.\n\nA mutex (cred_replace_mutex) is added to the task_struct to control the effect\nof PTRACE_ATTACHED on credential calculations, particularly with respect to\nexecve().\n\nWith this patch, the contents of an active credentials struct may not be\nchanged directly; rather a new set of credentials must be prepared, modified\nand committed using something like the following sequence of events:\n\n\tstruct cred *new \u003d prepare_creds();\n\tint ret \u003d blah(new);\n\tif (ret \u003c 0) {\n\t\tabort_creds(new);\n\t\treturn ret;\n\t}\n\treturn commit_creds(new);\n\nThere are some exceptions to this rule: the keyrings pointed to by the active\ncredentials may be instantiated - keyrings violate the COW rule as managing\nCOW keyrings is tricky, given that it is possible for a task to directly alter\nthe keys in a keyring in use by another task.\n\nTo help enforce this, various pointers to sets of credentials, such as those in\nthe task_struct, are declared const.  The purpose of this is compile-time\ndiscouragement of altering credentials through those pointers.  Once a set of\ncredentials has been made public through one of these pointers, it may not be\nmodified, except under special circumstances:\n\n  (1) Its reference count may incremented and decremented.\n\n  (2) The keyrings to which it points may be modified, but not replaced.\n\nThe only safe way to modify anything else is to create a replacement and commit\nusing the functions described in Documentation/credentials.txt (which will be\nadded by a later patch).\n\nThis patch and the preceding patches have been tested with the LTP SELinux\ntestsuite.\n\nThis patch makes several logical sets of alteration:\n\n (1) execve().\n\n     This now prepares and commits credentials in various places in the\n     security code rather than altering the current creds directly.\n\n (2) Temporary credential overrides.\n\n     do_coredump() and sys_faccessat() now prepare their own credentials and\n     temporarily override the ones currently on the acting thread, whilst\n     preventing interference from other threads by holding cred_replace_mutex\n     on the thread being dumped.\n\n     This will be replaced in a future patch by something that hands down the\n     credentials directly to the functions being called, rather than altering\n     the task\u0027s objective credentials.\n\n (3) LSM interface.\n\n     A number of functions have been changed, added or removed:\n\n     (*) security_capset_check(), -\u003ecapset_check()\n     (*) security_capset_set(), -\u003ecapset_set()\n\n     \t Removed in favour of security_capset().\n\n     (*) security_capset(), -\u003ecapset()\n\n     \t New.  This is passed a pointer to the new creds, a pointer to the old\n     \t creds and the proposed capability sets.  It should fill in the new\n     \t creds or return an error.  All pointers, barring the pointer to the\n     \t new creds, are now const.\n\n     (*) security_bprm_apply_creds(), -\u003ebprm_apply_creds()\n\n     \t Changed; now returns a value, which will cause the process to be\n     \t killed if it\u0027s an error.\n\n     (*) security_task_alloc(), -\u003etask_alloc_security()\n\n     \t Removed in favour of security_prepare_creds().\n\n     (*) security_cred_free(), -\u003ecred_free()\n\n     \t New.  Free security data attached to cred-\u003esecurity.\n\n     (*) security_prepare_creds(), -\u003ecred_prepare()\n\n     \t New. Duplicate any security data attached to cred-\u003esecurity.\n\n     (*) security_commit_creds(), -\u003ecred_commit()\n\n     \t New. Apply any security effects for the upcoming installation of new\n     \t security by commit_creds().\n\n     (*) security_task_post_setuid(), -\u003etask_post_setuid()\n\n     \t Removed in favour of security_task_fix_setuid().\n\n     (*) security_task_fix_setuid(), -\u003etask_fix_setuid()\n\n     \t Fix up the proposed new credentials for setuid().  This is used by\n     \t cap_set_fix_setuid() to implicitly adjust capabilities in line with\n     \t setuid() changes.  Changes are made to the new credentials, rather\n     \t than the task itself as in security_task_post_setuid().\n\n     (*) security_task_reparent_to_init(), -\u003etask_reparent_to_init()\n\n     \t Removed.  Instead the task being reparented to init is referred\n     \t directly to init\u0027s credentials.\n\n\t NOTE!  This results in the loss of some state: SELinux\u0027s osid no\n\t longer records the sid of the thread that forked it.\n\n     (*) security_key_alloc(), -\u003ekey_alloc()\n     (*) security_key_permission(), -\u003ekey_permission()\n\n     \t Changed.  These now take cred pointers rather than task pointers to\n     \t refer to the security context.\n\n (4) sys_capset().\n\n     This has been simplified and uses less locking.  The LSM functions it\n     calls have been merged.\n\n (5) reparent_to_kthreadd().\n\n     This gives the current thread the same credentials as init by simply using\n     commit_thread() to point that way.\n\n (6) __sigqueue_alloc() and switch_uid()\n\n     __sigqueue_alloc() can\u0027t stop the target task from changing its creds\n     beneath it, so this function gets a reference to the currently applicable\n     user_struct which it then passes into the sigqueue struct it returns if\n     successful.\n\n     switch_uid() is now called from commit_creds(), and possibly should be\n     folded into that.  commit_creds() should take care of protecting\n     __sigqueue_alloc().\n\n (7) [sg]et[ug]id() and co and [sg]et_current_groups.\n\n     The set functions now all use prepare_creds(), commit_creds() and\n     abort_creds() to build and check a new set of credentials before applying\n     it.\n\n     security_task_set[ug]id() is called inside the prepared section.  This\n     guarantees that nothing else will affect the creds until we\u0027ve finished.\n\n     The calling of set_dumpable() has been moved into commit_creds().\n\n     Much of the functionality of set_user() has been moved into\n     commit_creds().\n\n     The get functions all simply access the data directly.\n\n (8) security_task_prctl() and cap_task_prctl().\n\n     security_task_prctl() has been modified to return -ENOSYS if it doesn\u0027t\n     want to handle a function, or otherwise return the return value directly\n     rather than through an argument.\n\n     Additionally, cap_task_prctl() now prepares a new set of credentials, even\n     if it doesn\u0027t end up using it.\n\n (9) Keyrings.\n\n     A number of changes have been made to the keyrings code:\n\n     (a) switch_uid_keyring(), copy_keys(), exit_keys() and suid_keys() have\n     \t all been dropped and built in to the credentials functions directly.\n     \t They may want separating out again later.\n\n     (b) key_alloc() and search_process_keyrings() now take a cred pointer\n     \t rather than a task pointer to specify the security context.\n\n     (c) copy_creds() gives a new thread within the same thread group a new\n     \t thread keyring if its parent had one, otherwise it discards the thread\n     \t keyring.\n\n     (d) The authorisation key now points directly to the credentials to extend\n     \t the search into rather pointing to the task that carries them.\n\n     (e) Installing thread, process or session keyrings causes a new set of\n     \t credentials to be created, even though it\u0027s not strictly necessary for\n     \t process or session keyrings (they\u0027re shared).\n\n(10) Usermode helper.\n\n     The usermode helper code now carries a cred struct pointer in its\n     subprocess_info struct instead of a new session keyring pointer.  This set\n     of credentials is derived from init_cred and installed on the new process\n     after it has been cloned.\n\n     call_usermodehelper_setup() allocates the new credentials and\n     call_usermodehelper_freeinfo() discards them if they haven\u0027t been used.  A\n     special cred function (prepare_usermodeinfo_creds()) is provided\n     specifically for call_usermodehelper_setup() to call.\n\n     call_usermodehelper_setkeys() adjusts the credentials to sport the\n     supplied keyring as the new session keyring.\n\n(11) SELinux.\n\n     SELinux has a number of changes, in addition to those to support the LSM\n     interface changes mentioned above:\n\n     (a) selinux_setprocattr() no longer does its check for whether the\n     \t current ptracer can access processes with the new SID inside the lock\n     \t that covers getting the ptracer\u0027s SID.  Whilst this lock ensures that\n     \t the check is done with the ptracer pinned, the result is only valid\n     \t until the lock is released, so there\u0027s no point doing it inside the\n     \t lock.\n\n(12) is_single_threaded().\n\n     This function has been extracted from selinux_setprocattr() and put into\n     a file of its own in the lib/ directory as join_session_keyring() now\n     wants to use it too.\n\n     The code in SELinux just checked to see whether a task shared mm_structs\n     with other tasks (CLONE_VM), but that isn\u0027t good enough.  We really want\n     to know if they\u0027re part of the same thread group (CLONE_THREAD).\n\n(13) nfsd.\n\n     The NFS server daemon now has to use the COW credentials to set the\n     credentials it is going to use.  It really needs to pass the credentials\n     down to the functions it calls, but it can\u0027t do that until other patches\n     in this series have been applied.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: James Morris \u003cjmorris@namei.org\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n"

When, CONFIG_DYNAMIC_PRINTK_DEBUG,\nis not set, debugging statements can still be enabled as before, often by\ndefining \u0027DEBUG\u0027 for the proper compilation unit. Thus, this patch set has no\naffect when CONFIG_DYNAMIC_PRINTK_DEBUG is not set.\n\nThe infrastructure currently ties into all pr_debug() and dev_dbg() calls. That\nis, if CONFIG_DYNAMIC_PRINTK_DEBUG is set, all pr_debug() and dev_dbg() calls\ncan be dynamically enabled/disabled on a per-module basis.\n\nFuture plans include extending this functionality to subsystems, that define \ntheir own debug levels and flags.\n\nUsage:\n\nDynamic debugging is controlled by the debugfs file, \n\u003cdebugfs\u003e/dynamic_printk/modules. This file contains a list of the modules that\ncan be enabled.

This capability\nis enabled by a new config variable CONFIG_RCU_CPU_STALL_DETECTOR, which\ndefaults disabled.\n\nThis is a debugging feature to detect infinite loops in kernel code, not\nsomething that non-kernel-hackers would be expected to care about.\n\nThis feature can detect looping CPUs in !PREEMPT builds and looping CPUs\nwith preemption disabled in PREEMPT builds.  This is essentially a port of\nthis functionality from the treercu patch, replacing the stall debug patch\nthat is already in tip/core/rcu (commit 67182ae1c4).\n\nThe changes from the patch in tip/core/rcu include making the config\nvariable name match that in treercu, changing from seconds to jiffies to\navoid spurious warnings, and printing a boot message when this feature\nis enabled.\n\nSigned-off-by: Paul E.
