      "message": "X.509: Fix certificate gathering\n\nFix the gathering of certificates from both the source tree and the build tree\nto correctly calculate the pathnames of all the certificates.\n\nThe problem was that if the default generated cert, signing_key.x509, didn\u0027t\nexist then it would not have a path attached and if it did, it would have a\npath attached.\n\nThis means that the contents of kernel/.x509.list would change between the\nfirst compilation in a directory and the second.  After the second it would\nremain stable because the signing_key.x509 file exists.\n\nThe consequence was that the kernel would get relinked unconditionally on the\nsecond recompilation.  The second recompilation would also show something like\nthis:\n\n   X.509 certificate list changed\n     CERTS   kernel/x509_certificate_list\n     - Including cert /home/torvalds/v2.6/linux/signing_key.x509\n     AS      kernel/system_certificates.o\n     LD      kernel/built-in.o\n\nwhich is why the relink would happen.\n\n\nUnfortunately, it isn\u0027t a simple matter of just sticking a path on the front\nof the filename of the certificate in the build directory as make can\u0027t then\nwork out how to build it.\n\nSo the path has to be prepended to the name for sorting and duplicate\nelimination and then removed for the make rule if it is in the build tree.\n\nReported-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n"

      "message": "Merge branch \u0027for-linus2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security\n\nPull security subsystem updates from James Morris:\n \"In this patchset, we finally get an SELinux update, with Paul Moore\n  taking over as maintainer of that code.\n\n  Also a significant update for the Keys subsystem, as well as\n  maintenance updates to Smack, IMA, TPM, and Apparmor\"\n\nand since I wanted to know more about the updates to key handling,\nhere\u0027s the explanation from David Howells on that:\n\n \"Okay.  There are a number of separate bits.  I\u0027ll go over the big bits\n  and the odd important other bit, most of the smaller bits are just\n  fixes and cleanups.  If you want the small bits accounting for, I can\n  do that too.\n\n   (1) Keyring capacity expansion.\n\n        KEYS: Consolidate the concept of an \u0027index key\u0027 for key access\n        KEYS: Introduce a search context structure\n        KEYS: Search for auth-key by name rather than target key ID\n        Add a generic associative array implementation.\n        KEYS: Expand the capacity of a keyring\n\n     Several of the patches are providing an expansion of the capacity of a\n     keyring.  Currently, the maximum size of a keyring payload is one page.\n     Subtract a small header and then divide up into pointers, that only gives\n     you ~500 pointers on an x86_64 box.  However, since the NFS idmapper uses\n     a keyring to store ID mapping data, that has proven to be insufficient to\n     the cause.\n\n     Whatever data structure I use to handle the keyring payload, it can only\n     store pointers to keys, not the keys themselves because several keyrings\n     may point to a single key.  This precludes inserting, say, and rb_node\n     struct into the key struct for this purpose.\n\n     I could make an rbtree of records such that each record has an rb_node\n     and a key pointer, but that would use four words of space per key stored\n     in the keyring.  It would, however, be able to use much existing code.\n\n     I selected instead a non-rebalancing radix-tree type approach as that\n     could have a better space-used/key-pointer ratio.  I could have used the\n     radix tree implementation that we already have and insert keys into it by\n     their serial numbers, but that means any sort of search must iterate over\n     the whole radix tree.  Further, its nodes are a bit on the capacious side\n     for what I want - especially given that key serial numbers are randomly\n     allocated, thus leaving a lot of empty space in the tree.\n\n     So what I have is an associative array that internally is a radix-tree\n     with 16 pointers per node where the index key is constructed from the key\n     type pointer and the key description.  This means that an exact lookup by\n     type+description is very fast as this tells us how to navigate directly to\n     the target key.\n\n     I made the data structure general in lib/assoc_array.c as far as it is\n     concerned, its index key is just a sequence of bits that leads to a\n     pointer.  It\u0027s possible that someone else will be able to make use of it\n     also.  FS-Cache might, for example.\n\n   (2) Mark keys as \u0027trusted\u0027 and keyrings as \u0027trusted only\u0027.\n\n        KEYS: verify a certificate is signed by a \u0027trusted\u0027 key\n        KEYS: Make the system \u0027trusted\u0027 keyring viewable by userspace\n        KEYS: Add a \u0027trusted\u0027 flag and a \u0027trusted only\u0027 flag\n        KEYS: Separate the kernel signature checking keyring from module signing\n\n     These patches allow keys carrying asymmetric public keys to be marked as\n     being \u0027trusted\u0027 and allow keyrings to be marked as only permitting the\n     addition or linkage of trusted keys.\n\n     Keys loaded from hardware during kernel boot or compiled into the kernel\n     during build are marked as being trusted automatically.  New keys can be\n     loaded at runtime with add_key().  They are checked against the system\n     keyring contents and if their signatures can be validated with keys that\n     are already marked trusted, then they are marked trusted also and can\n     thus be added into the master keyring.\n\n     Patches from Mimi Zohar make this usable with the IMA keyrings also.\n\n   (3) Remove the date checks on the key used to validate a module signature.\n\n        X.509: Remove certificate date checks\n\n     It\u0027s not reasonable to reject a signature just because the key that it was\n     generated with is no longer valid datewise - especially if the kernel\n     hasn\u0027t yet managed to set the system clock when the first module is\n     loaded - so just remove those checks.\n\n   (4) Make it simpler to deal with additional X.509 being loaded into the kernel.\n\n        KEYS: Load *.x509 files into kernel keyring\n        KEYS: Have make canonicalise the paths of the X.509 certs better to deduplicate\n\n     The builder of the kernel now just places files with the extension \".x509\"\n     into the kernel source or build trees and they\u0027re concatenated by the\n     kernel build and stuffed into the appropriate section.\n\n   (5) Add support for userspace kerberos to use keyrings.\n\n        KEYS: Add per-user_namespace registers for persistent per-UID kerberos caches\n        KEYS: Implement a big key type that can save to tmpfs\n\n     Fedora went to, by default, storing kerberos tickets and tokens in tmpfs.\n     We looked at storing it in keyrings instead as that confers certain\n     advantages such as tickets being automatically deleted after a certain\n     amount of time and the ability for the kernel to get at these tokens more\n     easily.\n\n     To make this work, two things were needed:\n\n     (a) A way for the tickets to persist beyond the lifetime of all a user\u0027s\n         sessions so that cron-driven processes can still use them.\n\n         The problem is that a user\u0027s session keyrings are deleted when the\n         session that spawned them logs out and the user\u0027s user keyring is\n         deleted when the UID is deleted (typically when the last log out\n         happens), so neither of these places is suitable.\n\n         I\u0027ve added a system keyring into which a \u0027persistent\u0027 keyring is\n         created for each UID on request.  Each time a user requests their\n         persistent keyring, the expiry time on it is set anew.  If the user\n         doesn\u0027t ask for it for, say, three days, the keyring is automatically\n         expired and garbage collected using the existing gc.  All the kerberos\n         tokens it held are then also gc\u0027d.\n\n     (b) A key type that can hold really big tickets (up to 1MB in size).\n\n         The problem is that Active Directory can return huge tickets with lots\n         of auxiliary data attached.  We don\u0027t, however, want to eat up huge\n         tracts of unswappable kernel space for this, so if the ticket is\n         greater than a certain size, we create a swappable shmem file and dump\n         the contents in there and just live with the fact we then have an\n         inode and a dentry overhead.  If the ticket is smaller than that, we\n         slap it in a kmalloc()\u0027d buffer\"\n\n* \u0027for-linus2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (121 commits)\n  KEYS: Fix keyring content gc scanner\n  KEYS: Fix error handling in big_key instantiation\n  KEYS: Fix UID check in keyctl_get_persistent()\n  KEYS: The RSA public key algorithm needs to select MPILIB\n  ima: define \u0027_ima\u0027 as a builtin \u0027trusted\u0027 keyring\n  ima: extend the measurement list to include the file signature\n  kernel/system_certificate.S: use real contents instead of macro GLOBAL()\n  KEYS: fix error return code in big_key_instantiate()\n  KEYS: Fix keyring quota misaccounting on key replacement and unlink\n  KEYS: Fix a race between negating a key and reading the error set\n  KEYS: Make BIG_KEYS boolean\n  apparmor: remove the \"task\" arg from may_change_ptraced_domain()\n  apparmor: remove parent task info from audit logging\n  apparmor: remove tsk field from the apparmor_audit_struct\n  apparmor: fix capability to not use the current task, during reporting\n  Smack: Ptrace access check mode\n  ima: provide hash algo info in the xattr\n  ima: enable support for larger default filedata hash algorithms\n  ima: define kernel parameter \u0027ima_template\u003d\u0027 to change configured default\n  ima: add Kconfig default measurement list template\n  ...\n"

This version prohibits\n  \tofflining CPU 0, but only when enabled via CONFIG_RCU_NOCB_CPU\u003dy.\n  \tRelaxing this constraint is in progress, but not yet ready\n  \tfor prime time.  These commits were posted to LKML at\n  \thttps://lkml.org/lkml/2012/10/30/724, and are at branch rcu/nocb.\n\n  2.\tChanges to SRCU that allows statically initialized srcu_struct\n  \tstructures.

These were posted to LKML at\n  \thttps://lkml.org/lkml/2012/10/30/739, and are at branch rcu/idle.\n\n  6.\tAdditional diagnostics for RCU\u0027s CPU stall warning facility,\n  \tposted to LKML at https://lkml.org/lkml/2012/10/30/315, and\n  \tare at branch rcu/stall.  The most notable change reduces the\n  \tdefault RCU CPU stall-warning time from 60 seconds to 21 seconds,\n  \tso that it once again happens sooner than the softlockup timeout.\n\n  7.\tDocumentation updates, which were posted to LKML at\n  \thttps://lkml.org/lkml/2012/10/30/280, and are at branch rcu/doc.\n  \tA couple of late-breaking changes were posted at\n  \thttps://lkml.org/lkml/2012/11/16/634 and\n  \thttps://lkml.org/lkml/2012/11/16/547.\n\n  8.\tMiscellaneous fixes, which were posted to LKML at\n  \thttps://lkml.org/lkml/2012/10/30/309, along with a late-breaking\n  \tchange posted at Fri, 16 Nov 2012 11:26:25 -0800 with message-ID\n  \t\u003c20121116192625.GA447@linux.vnet.ibm.com\u003e, but which lkml.org\n  \tseems to have missed.

Most of the activity was on the tooling side.\n\n  Higher level changes:\n\n   - New \u0027perf kvm\u0027 analysis tool, from Xiao Guangrong.\n\n   - New \u0027perf trace\u0027 system-wide tracing tool\n\n   - uprobes fixes + cleanups from Oleg Nesterov.\n\n   - Lots of patches to make perf build on Android out of box, from\n     Irina Tirdea\n\n   - Extend ftrace function tracing utility to be more dynamic for its\n     users.  It allows for data passing to the callback functions, as\n     well as reading regs as if a breakpoint were to trigger at function\n     entry.\n\n     The main goal of this patch series was to allow kprobes to use\n     ftrace as an optimized probe point when a probe is placed on an\n     ftrace nop.  With lots of help from Masami Hiramatsu, and going\n     through lots of iterations, we finally came up with a good\n     solution.\n\n   - Add cpumask for uncore pmu, use it in \u0027stat\u0027, from Yan, Zheng.\n\n   - Various tracing updates from Steve Rostedt\n\n   - Clean up and improve \u0027perf sched\u0027 performance by elliminating lots\n     of needless calls to libtraceevent.\n\n   - Event group parsing support, from Jiri Olsa\n\n   - UI/gtk refactorings and improvements from Namhyung Kim\n\n   - Add support for non-tracepoint events in perf script python, from\n     Feng Tang\n\n   - Add --symbols to \u0027script\u0027, similar to the one in \u0027report\u0027, from\n     Feng Tang.\n\n  Infrastructure enhancements and fixes:\n\n   - Convert the trace builtins to use the growing evsel/evlist\n     tracepoint infrastructure, removing several open coded constructs\n     like switch like series of strcmp to dispatch events, etc.\n     Basically what had already been showcased in \u0027perf sched\u0027.\n\n   - Add evsel constructor for tracepoints, that uses libtraceevent just\n     to parse the /format events file, use it in a new \u0027perf test\u0027 to\n     make sure the libtraceevent format parsing regressions can be more\n     readily caught.\n\n   - Some strange errors were happening in some builds, but not on the\n     next, reported by several people, problem was some parser related\n     files, generated during the build, didn\u0027t had proper make deps, fix\n     from Eric Sandeen.\n\n   - Introduce struct and cache information about the environment where\n     a perf.data file was captured, from Namhyung Kim.\n\n   - Fix handling of unresolved samples when --symbols is used in\n     \u0027report\u0027, from Feng Tang.\n\n   - Add union member access support to \u0027probe\u0027, from Hyeoncheol Lee.\n\n   - Fixups to die() removal, from Namhyung Kim.\n\n   - Render fixes for the TUI, from Namhyung Kim.\n\n   - Don\u0027t enable annotation in non symbolic view, from Namhyung Kim.\n\n   - Fix pipe mode in \u0027report\u0027, from Namhyung Kim.\n\n   - Move related stats code from stat to util/, will be used by the\n     \u0027stat\u0027 kvm tool, from Xiao Guangrong.\n\n   - Remove die()/exit() calls from several tools.\n\n   - Resolve vdso callchains, from Jiri Olsa\n\n   - Don\u0027t pass const char pointers to basename, so that we can\n     unconditionally use libgen.h and thus avoid ifdef BIONIC lines,\n     from David Ahern\n\n   - Refactor hist formatting so that it can be reused with the GTK\n     browser, From Namhyung Kim\n\n   - Fix build for another rbtree.c change, from Adrian Hunter.\n\n   - Make \u0027perf diff\u0027 command work with evsel hists, from Jiri Olsa.\n\n   - Use the only field_sep var that is set up: symbol_conf.field_sep,\n     fix from Jiri Olsa.\n\n   - .gitignore compiled python binaries, from Namhyung Kim.\n\n   - Get rid of die() in more libtraceevent places, from Namhyung Kim.\n\n   -

Fix hardware cache event name generation, fix from Jiri Olsa\n\n   - Add round trip test for sw, hw and cache event names, catching the\n     problem Jiri fixed, after Jiri\u0027s patch, the test passes\n     successfully.\n\n   - Clean target should do clean for lib/traceevent too, fix from David\n     Ahern\n\n   - Check the right variable for allocation failure, fix from Namhyung\n     Kim\n\n   - Set up evsel-\u003etp_format regardless of evsel-\u003ename being set\n     already, fix from Namhyung Kim\n\n   - Oprofile fixes from Robert Richter.\n\n   - Remove perf_event_attr needless version inflation, from Jiri Olsa\n\n   - Introduce libtraceevent strerror like error reporting facility,\n     from Namhyung Kim\n\n   -

Based on a new \u0027asm goto\u0027 inline\nassembly gcc mechanism, we can now branch to labels from an \u0027asm goto\u0027\nstatment. This allows us to create a \u0027no-op\u0027 fastpath, which can subsequently\nbe patched with a jump to the slowpath code. This is useful for code which\nmight be rarely used, but which we\u0027d like to be able to call, if needed.\nTracepoints are the current usecase that these are being implemented for.\n\nAcked-by: David S.

Using Ingo\u0027s\nsuggestion, I combined the two functionalities into one file:\nkernel/watchdog.c.\n\nNow both the nmi_watchdog (or hardlockup detector) and softlockup\ndetector sit on top of the perf event subsystem, which is run every\n60 seconds or so to see if there are any lockups.\n\nTo detect hardlockups, cpus not responding to interrupts, I\nimplemented an hrtimer that runs 5 times for every perf event\noverflow event.  If that stops counting on a cpu, then the cpu is\nmost likely in trouble.\n\nTo detect softlockups, tasks not yielding to the scheduler, I used the\nprevious kthread idea that now gets kicked every time the hrtimer fires.\nIf the kthread isn\u0027t being scheduled neither is anyone else and the\nwarning is printed to the console.\n\nI tested this on x86_64 and both the softlockup and hardlockup paths\nwork.\n\nV2:\n- cleaned up the Kconfig and softlockup combination\n- surrounded hardlockup cases with #ifdef CONFIG_PERF_EVENTS_NMI\n- seperated out the softlockup case from perf event subsystem\n- re-arranged the enabling/disabling nmi watchdog from proc space\n- added cpumasks for hardlockup failure cases\n- removed fallback to soft events if no PMU exists for hard events\n\nV3:\n- comment cleanups\n- drop support for older softlockup code\n- per_cpu cleanups\n- completely remove software clock base hardlockup detector\n- use per_cpu masking on hard/soft lockup detection\n- #ifdef cleanups\n- rename config option NMI_WATCHDOG to LOCKUP_DETECTOR\n- documentation additions\n\nV4:\n- documentation fixes\n- convert per_cpu to __get_cpu_var\n- powerpc compile fixes\n\nV5:\n- split apart warn flags for hard and soft lockups\n\nTODO:\n- figure out how to make an arch-agnostic clock2cycles call\n  (if possible) to feed into perf events as a sample period\n\n[fweisbec: merged conflict patch]\n\nSigned-off-by: Don Zickus \u003cdzickus@redhat.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Cyrill Gorcunov \u003cgorcunov@gmail.com\u003e\nCc: Eric Paris \u003ceparis@redhat.com\u003e\nCc: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nLKML-Reference: \u003c1273266711-18706-2-git-send-email-dzickus@redhat.com\u003e\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\n"

      "message": "rcu: \"Tiny RCU\", The Bloatwatch Edition\n\nThis patch is a version of RCU designed for !SMP provided for a\nsmall-footprint RCU implementation.  In particular, the\nimplementation of synchronize_rcu() is extremely lightweight and\nhigh performance. It passes rcutorture testing in each of the\nfour relevant configurations (combinations of NO_HZ and PREEMPT)\non x86.  This saves about 1K bytes compared to old Classic RCU\n(which is no longer in mainline), and more than three kilobytes\ncompared to Hierarchical RCU (updated to 2.6.30):\n\n\tCONFIG_TREE_RCU:\n\n\t   text\t   data\t    bss\t    dec\t    filename\n\t    183       4       0     187     kernel/rcupdate.o\n\t   2783     520      36    3339     kernel/rcutree.o\n\t\t\t\t   3526 Total (vs 4565 for v7)\n\n\tCONFIG_TREE_PREEMPT_RCU:\n\n\t   text\t   data\t    bss\t    dec\t    filename\n\t    263       4       0     267     kernel/rcupdate.o\n\t   4594     776      52    5422     kernel/rcutree.o\n\t   \t\t\t   5689 Total (6155 for v7)\n\n\tCONFIG_TINY_RCU:\n\n\t   text\t   data\t    bss\t    dec\t    filename\n\t     96       4       0     100     kernel/rcupdate.o\n\t    734      24       0     758     kernel/rcutiny.o\n\t    \t\t\t    858 Total (vs 848 for v7)\n\nThe above is for x86.  Your mileage may vary on other platforms.\nFurther compression is possible, but is being procrastinated.\n\nChanges from v7 (http://lkml.org/lkml/2009/10/9/388)\n\no\tApply Lai Jiangshan\u0027s review comments (aside from\nmight_sleep() \tin synchronize_sched(), which is covered by SMP builds).\n\no\tFix up expedited primitives.\n\nChanges from v6 (http://lkml.org/lkml/2009/9/23/293).\n\no\tForward ported to put it into the 2.6.33 stream.\n\no\tAdded lockdep support.\n\no\tMake lightweight rcu_barrier.\n\nChanges from v5 (http://lkml.org/lkml/2009/6/23/12).\n\no\tPorted to latest pre-2.6.32 merge window kernel.\n\n\t- Renamed rcu_qsctr_inc() to rcu_sched_qs().\n\t- Renamed rcu_bh_qsctr_inc() to rcu_bh_qs().\n\t- Provided trivial rcu_cpu_notify().\n\t- Provided trivial exit_rcu().\n\t- Provided trivial rcu_needs_cpu().\n\t- Fixed up the rcu_*_enter/exit() functions in linux/hardirq.h.\n\no\tRemoved the dependence on EMBEDDED, with a view to making\n\tTINY_RCU default for !SMP at some time in the future.\n\no\tAdded (trivial) support for expedited grace periods.\n\nChanges from v4 (http://lkml.org/lkml/2009/5/2/91) include:\n\no\tSqueeze the size down a bit further by removing the\n\t-\u003ecompleted field from struct rcu_ctrlblk.\n\no\tThis permits synchronize_rcu() to become the empty function.\n\tPrevious concerns about rcutorture were unfounded, as\n\trcutorture correctly handles a constant value from\n\trcu_batches_completed() and rcu_batches_completed_bh().\n\nChanges from v3 (http://lkml.org/lkml/2009/3/29/221) include:\n\no\tChanged rcu_batches_completed(), rcu_batches_completed_bh()\n\trcu_enter_nohz(), rcu_exit_nohz(), rcu_nmi_enter(), and\n\trcu_nmi_exit(), to be static inlines, as suggested by David\n\tHowells.  Doing this saves about 100 bytes from rcutiny.o.\n\t(The numbers between v3 and this v4 of the patch are not directly\n\tcomparable, since they are against different versions of Linux.)\n\nChanges from v2 (http://lkml.org/lkml/2009/2/3/333) include:\n\no\tFix whitespace issues.\n\no\tChange short-circuit \"||\" operator to instead be \"+\" in order\nto \tfix performance bug noted by \"kraai\" on LWN.\n\n\t\t(http://lwn.net/Articles/324348/)\n\nChanges from v1 (http://lkml.org/lkml/2009/1/13/440) include:\n\no\tThis version depends on EMBEDDED as well as !SMP, as suggested\n\tby Ingo.\n\no\tUpdated rcu_needs_cpu() to unconditionally return zero,\n\tpermitting the CPU to enter dynticks-idle mode at any time.\n\tThis works because callbacks can be invoked upon entry to\n\tdynticks-idle mode.\n\no\tPaul is now OK with this being included, based on a poll at\nthe \tKernel Miniconf at linux.conf.au, where about ten people said\n\tthat they cared about saving 900 bytes on single-CPU systems.\n\no\tApplies to both mainline and tip/core/rcu.\n\nSigned-off-by: Paul E.
