Soft-lockups detected as a consequence of this race was\nreported earlier at https://lkml.org/lkml/2011/8/24/185. (Thanks to Cong Meng\nfor finding out that the root-cause of this issue is the race condition\nbetween br_write_[un]lock() and CPU hotplug, which results in the lock states\ngetting messed up).\n\nFixing this race by just adding {get,put}_online_cpus() at appropriate places\nin *_global_[un]lock_online() is not a good option, because, then suddenly\nbr_write_[un]lock() would become blocking, whereas they have been kept as\nnon-blocking all this time, and we would want to keep them that way.\n\nSo, overall, we want to ensure 3 things:\n1. br_write_lock() and br_write_unlock() must remain as non-blocking.\n2. The corresponding lock and unlock of the per-cpu spinlocks must not happen\n for different sets of CPUs.\n3. Either prevent any new CPU online operation in between this lock-unlock, or\n ensure that the newly onlined CPU does not proceed with its corresponding\n per-cpu spinlock unlocked.\n\nTo achieve all this:\n(a) We introduce a new spinlock that is taken by the *_global_lock_online()\n routine and released by the *_global_unlock_online() routine.\n(b) We register a callback for CPU hotplug notifications, and this callback\n takes the same spinlock as above.\n(c) We maintain a bitmap which is close to the cpu_online_mask, and once it is\n initialized in the lock_init() code, all future updates to it are done in\n the callback, under the above spinlock.\n(d) The above bitmap is used (instead of cpu_online_mask) while locking and\n unlocking the per-cpu locks.\n\nThe callback takes the spinlock upon the CPU_UP_PREPARE event. So, if the\nbr_write_lock-unlock sequence is in progress, the callback keeps spinning,\nthus preventing the CPU online operation till the lock-unlock sequence is\ncomplete. This takes care of requirement (3).\n\nThe bitmap that we maintain remains unmodified throughout the lock-unlock\nsequence, since all updates to it are managed by the callback, which takes\nthe same spinlock as the one taken by the lock code and released only by the\nunlock routine. Combining this with (d) above, satisfies requirement (2).\n\nOverall, since we use a spinlock (mentioned in (a)) to prevent CPU hotplug\noperations from racing with br_write_lock-unlock, requirement (1) is also\ntaken care of.\n\nBy the way, it is to be noted that a CPU offline operation can actually run\nin parallel with our lock-unlock sequence, because our callback doesn\u0027t react\nto notifications earlier than CPU_DEAD (in order to maintain our bitmap\nproperly). And this means, since we use our own bitmap (which is stale, on\npurpose) during the lock-unlock sequence, we could end up unlocking the\nper-cpu lock of an offline CPU (because we had locked it earlier, when the\nCPU was online), in order to satisfy requirement (2). But this is harmless,\nthough it looks a bit awkward.\n\nDebugged-by: Cong Meng \u003cmc@linux.vnet.ibm.com\u003e\nSigned-off-by: Srivatsa S.

The root cause is that when __d_path() misses the root\nit had been told to look for, it stores the location of the most remote ancestor\nin *root. Without grabbing references. Sure, at the moment of call it had\nbeen pinned down by what we have in *path. And if we raced with umount -l, we\ncould have very well stopped at vfsmount/dentry that got freed as soon as\nprepend_path() dropped vfsmount_lock.\n\nIt is safe to compare these pointers with pre-existing (and known to be still\nalive) vfsmount and dentry, as long as all we are asking is \"is it the same\naddress?\". Dereferencing is not safe and apparmor ended up stepping into\nthat. d_namespace_path() really wants to examine the place where we stopped,\neven if it\u0027s not connected to our namespace. As the result, it looked\nat -\u003ed_sb-\u003es_magic of a dentry that might\u0027ve been already freed by that point.\nAll other callers had been careful enough to avoid that, but it\u0027s really\na bad interface - it invites that kind of trouble.\n\nThe fix is fairly straightforward, even though it\u0027s bigger than I\u0027d like:\n\t* prepend_path() root argument becomes const.\n\t* __d_path() is never called with NULL/NULL root. It was a kludge\nto start with. Instead, we have an explicit function - d_absolute_root().\nSame as __d_path(), except that it doesn\u0027t get root passed and stops where\nit stops. apparmor and tomoyo are using it.\n\t* __d_path() returns NULL on path outside of root. The main\ncaller is show_mountinfo() and that\u0027s precisely what we pass root for - to\nskip those outside chroot jail. Those who don\u0027t want that can (and do)\nuse d_path().\n\t* __d_path() root argument becomes const. Everyone agrees, I hope.\n\t* apparmor does *NOT* try to use __d_path() or any of its variants\nwhen it sees that path-\u003emnt is an internal vfsmount. In that case it\u0027s\ndefinitely not mounted anywhere and dentry_path() is exactly what we want\nthere. Handling of sysctl()-triggered weirdness is moved to that place.\n\t* if apparmor is asked to do pathname relative to chroot jail\nand __d_path() tells it we it\u0027s not in that jail, the sucker just calls\nd_absolute_path() instead. That\u0027s the other remaining caller of __d_path(),\nBTW.\n * seq_path_root() does _NOT_ return -ENAMETOOLONG (it\u0027s stupid anyway -\nthe normal seq_file logics will take care of growing the buffer and redoing\nthe call of -\u003eshow() just fine). However, if it gets path not reachable\nfrom root, it returns SEQ_SKIP.

This will guarantee that get_page_unless_zero() can never\nsucceed on any tail page. page_tail-\u003e_mapcount is guaranteed zero and\nis unused for all tail pages of a compound page, so we can simply\naccount the tail page references there and transfer them to\ntail_page-\u003e_count in __split_huge_page_refcount() (in addition to the\nhead_page-\u003e_mapcount).\n\nWhile debugging this s/_count/_mapcount/ change I also noticed get_page is\ncalled by direct-io.c on pages returned by get_user_pages. That wasn\u0027t\nentirely safe because the two atomic_inc in get_page weren\u0027t atomic. As\nopposed to other get_user_page users like secondary-MMU page fault to\nestablish the shadow pagetables would never call any superflous get_page\nafter get_user_page returns. It\u0027s safer to make get_page universally safe\nfor tail pages and to use get_page_foll() within follow_page (inside\nget_user_pages()). get_page_foll() is safe to do the refcounting for tail\npages without taking any locks because it is run within PT lock protected\ncritical sections (PT lock for pte and page_table_lock for\npmd_trans_huge).\n\nThe standard get_page() as invoked by direct-io instead will now take\nthe compound_lock but still only for tail pages. The direct-io paths\nare usually I/O bound and the compound_lock is per THP so very\nfinegrined, so there\u0027s no risk of scalability issues with it. A simple\ndirect-io benchmarks with all lockdep prove locking and spinlock\ndebugging infrastructure enabled shows identical performance and no\noverhead. So it\u0027s worth it. Ideally direct-io should stop calling\nget_page() on pages returned by get_user_pages().

It, however, may access pages\nfield of vm_struct where a page was not allocated. This results in a null\npointer access and leads to a kernel panic.\n\nWhy this happens: In __vmalloc_node_range() called from vmalloc(), newly\nallocated vm_struct is added to vmlist at __get_vm_area_node() and then,\nsome fields of vm_struct such as nr_pages and pages are set at\n__vmalloc_area_node(). In other words, it is added to vmlist before it is\nfully initialized. At the same time, when the /proc/vmallocinfo is read,\nit accesses the pages field of vm_struct according to the nr_pages field\nat show_numa_info(). Thus, a null pointer access happens.\n\nThe patch adds the newly allocated vm_struct to the vmlist *after* it is\nfully initialized. So, it can avoid accessing the pages field with\nunallocated page when show_numa_info() is called.\n\nSigned-off-by: Mitsuo Hayasaka \u003cmitsuo.hayasaka.hu@hitachi.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Namhyung Kim \u003cnamhyung@gmail.com\u003e\nCc: \"Paul E.

It will eventually\nupdate those bits ... in the struct page, but not in the PTE.\n\nAdditionally, it will not handle the lazy TLB flushing that can be\nrequired by some architectures in the fault case.\n\nBasically, gup is the wrong interface for the job. The patch provides a\nmore appropriate one which boils down to just calling handle_mm_fault()\nsince what we are trying to do is simulate a real page fault.\n\nThe futex code currently attempts to write to user memory within a\npagefault disabled section, and if that fails, tries to fix it up using\nget_user_pages().\n\nThis doesn\u0027t work on archs where the dirty and young bits are maintained\nby software, since they will gate access permission in the TLB, and will\nnot be updated by gup().\n\nIn addition, there\u0027s an expectation on some archs that a spurious write\nfault triggers a local TLB flush, and that is missing from the picture as\nwell.\n\nI decided that adding those \"features\" to gup() would be too much for this\nalready too complex function, and instead added a new simpler\nfixup_user_fault() which is essentially a wrapper around handle_mm_fault()\nwhich the futex code can call.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: fix some nits Darren saw, fiddle comment layout]\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nReported-by: Shan Hai \u003chaishan.bai@gmail.com\u003e\nTested-by: Shan Hai \u003chaishan.bai@gmail.com\u003e\nCc: David Laight \u003cDavid.Laight@ACULAB.COM\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Darren Hart \u003cdarren.hart@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "892cd4a38f0d379dfdbc1a0a45eaa31a89976796", "tree": "edc8337ed3451ff819dc20e3436b5019479b6c87", "parents": [ "f45c1d4647a37feee31f4bca9ebd9b90ebdc98a3" ], "author": { "name": "Peng Tao", "email": "peng_tao@emc.com", "time": "Sat Jul 30 20:52:33 2011 -0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Thu Aug 04 21:58:37 2011 -0700" }, "message": "pnfs: let layoutcommit handle a list of lseg\n\ncommit a9bae5666d0510ad69bdb437371c9a3e6b770705 upstream.\n\nThere can be multiple lseg per file, so layoutcommit should be\nable to handle it.\n\n[Needed in v3.0]\nSigned-off-by: Peng Tao \u003cpeng_tao@emc.com\u003e\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\nSigned-off-by: Jim Rees \u003crees@umich.edu\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "6f437783919467437f19ec534a0317aef2fd2584", "tree": "01e8500766574786b1fd63e9a3090ac2c45777f9", "parents": [ "63ab4325d0df2ccefaeb932210d4046f2223e338" ], "author": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Sat Jul 09 16:43:22 2011 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Thu Aug 04 21:58:34 2011 -0700" }, "message": "firewire: cdev: prevent race between first get_info ioctl and bus reset event queuing\n\ncommit 93b37905f70083d6143f5f4dba0a45cc64379a62 upstream.\n\nBetween open(2) of a /dev/fw* and the first FW_CDEV_IOC_GET_INFO\nioctl(2) on it, the kernel already queues FW_CDEV_EVENT_BUS_RESET events\nto be read(2) by the client. The get_info ioctl is practically always\nissued right away after open, hence this condition only occurs if the\nclient opens during a bus reset, especially during a rapid series of bus\nresets.\n\nThe problem with this condition is twofold:\n\n - These bus reset events carry the (as yet undocumented) @closure\n value of 0. But it is not the kernel\u0027s place to choose closures;\n they are privat to the client. E.g., this 0 value forced from the\n kernel makes it unsafe for clients to dereference it as a pointer to\n a closure object without NULL pointer check.\n\n - It is impossible for clients to determine the relative order of bus\n reset events from get_info ioctl(2) versus those from read(2),\n except in one way: By comparison of closure values. Again, such a\n procedure imposes complexity on clients and reduces freedom in use\n of the bus reset closure.\n\nSo, change the ABI to suppress queuing of bus reset events before the\nfirst FW_CDEV_IOC_GET_INFO ioctl was issued by the client.\n\nNote, this ABI change cannot be version-controlled. The kernel cannot\ndistinguish old from new clients before the first FW_CDEV_IOC_GET_INFO\nioctl.\n\nWe will try to back-merge this change into currently maintained stable/\nlongterm series, and we only document the new behaviour.

These deadlocks would result from RCU incorrectly\nbelieving that the just-ended RCU read-side critical section had been\npreempted and/or boosted. If that RCU read-side critical section was\nexecuted with either rq or pi locks held, RCU\u0027s ensuing (incorrect)\ncalls to the scheduler would cause the scheduler to attempt to once\nagain acquire the rq and pi locks, resulting in deadlock. More complex\ndeadlock cycles are also possible, involving multiple rq and pi locks\nas well as locks from multiple rcu_node structures.\n\nThis commit fixes synchronization by creating -\u003ercu_boosted field in\ntask_struct that is accessed and modified only when holding the -\u003elock\nin the rcu_node structure on which the task is queued (on that rcu_node\nstructure\u0027s -\u003eblkd_tasks list). This results in tasks accessing only\ntheir own current-\u003ercu_read_unlock_special fields, making unsynchronized\naccess once again legal, and keeping the rcu_read_unlock() fastpath free\nof atomic instructions and memory barriers.\n\nThe reason that the rcu_read_unlock() fastpath does not need to access\nthe new current-\u003ercu_boosted field is that this new field cannot\nbe non-zero unless the RCU_READ_UNLOCK_BLOCKED bit is set in the\ncurrent-\u003ercu_read_unlock_special field. Therefore, rcu_read_unlock()\nneed only test current-\u003ercu_read_unlock_special: if that is zero, then\ncurrent-\u003ercu_boosted must also be zero.\n\nThis bug does not affect TINY_PREEMPT_RCU because this implementation\nof RCU accesses current-\u003ercu_read_unlock_special with irqs disabled,\nthus preventing races on the !SMP systems that TINY_PREEMPT_RCU runs on.\n\nMaybe-reported-by: Dave Jones \u003cdavej@redhat.com\u003e\nMaybe-reported-by: Sergey Senozhatsky \u003csergey.senozhatsky@gmail.com\u003e\nReported-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Paul E.

This\nnever happens due to the peer\u0027s zero window not acknowledging\nthe continuously retransmitted data chunks. Although the\nerror counter is incremented for each failed retransmission,\nthe receiving of the SACK announcing the zero window clears\nthe error count again immediately. Also heartbeat requests\ncontinue to be sent periodically. The peer acknowledges these\nrequests causing the error counter to be reset as well.\n\nThis patch changes behaviour to only reset the overall error\ncounter for the above rules while not in shutdown. After\nreaching the maximum number of retransmission attempts, the\nT5 shutdown guard timer is scheduled to give the receiver\nsome additional time to recover. The timer is stopped as soon\nas the receiver acknowledges any data.\n\nThe issue can be easily reproduced by establishing a sctp\nassociation over the loopback device, constantly queueing\ndata at the sender while not reading any at the receiver.\nWait for the window to reach zero, then initiate a shutdown\nby killing both processes simultaneously. The association\nwill never be freed and the chunks on the retransmission\nqueue will be retransmitted indefinitely.\n\nSigned-off-by: Thomas Graf \u003ctgraf@infradead.org\u003e\nAcked-by: Vlad Yasevich \u003cvladislav.yasevich@hp.com\u003e\nSigned-off-by: David S.

Replace irq_gc_ack() with some\n{set,clr}_bit variants allows to handle both cases.\n\nNote that this patch affects the following SoCs: Davinci, Samsung and\nOrion. Except for this last, the change is minor: irq_gc_ack() is just\nrenamed into irq_gc_ack_set_bit().\n\nFor the Orion SoCs, the edge GPIO interrupts support is currently\nbroken. irq_gc_ack() try to acknowledge a such interrupt by setting\nthe corresponding cause register bit. The Orion GPIO device expect the\nopposite. To fix this issue, the irq_gc_ack_clr_bit() variant is used.\n\nTested on Network Space v2.\n\nReported-by: Joey Oravec \u003cjoravec@drewtech.com\u003e\nSigned-off-by: Simon Guinot
