Here is a set of patches to tackle that problem. The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data structure is larger than the machine word size memcpy is used and a warning is emitted. The next patches fix up several in-tree users of ACCESS_ONCE on non-scalar types. This does not yet contain a patch that forces ACCESS_ONCE to work only on scalar types. This is targetted for the next merge window as Linux next already contains new offenders regarding ACCESS_ONCE vs. non-scalar types" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/borntraeger/linux: s390/kvm: REPLACE barrier fixup with READ_ONCE arm/spinlock: Replace ACCESS_ONCE with READ_ONCE arm64/spinlock: Replace ACCESS_ONCE READ_ONCE mips/gup: Replace ACCESS_ONCE with READ_ONCE x86/gup: Replace ACCESS_ONCE with READ_ONCE x86/spinlock: Replace ACCESS_ONCE with READ_ONCE mm: replace ACCESS_ONCE with READ_ONCE or barriers kernel: Provide READ_ONCE and ASSIGN_ONCE 21 December 2014, 00:48:59 UTC

Unfortunaly one of the real problematic commits was right at the beginning, so I rebased this portion of the pending patches without the offenders. It would be great to get this into 3.19. That makes reworking the problematic parts simpler. The usual tip testing did not unearth any issues and it is fully bisectible now. I'm pretty confident that this wont affect the calmness of the xmas season. Changes: - Split the convoluted io_apic.c code into domain specific parts (vector, ioapic, msi, htirq) - Introduce proper helper functions to retrieve irq specific data instead of open coded dereferencing of pointers - Preparatory work for ioapic hotplug and irqdomain conversion - Removal of the non functional pci-ioapic driver - Removal of unused irq entry stubs - Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC allocations for everything which is called from there. - Small cleanups and fixes" * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (36 commits) iommu/amd: Use helpers to access irq_cfg data structure associated with IRQ iommu/vt-d: Use helpers to access irq_cfg data structure associated with IRQ x86: irq_remapping: Use helpers to access irq_cfg data structure associated with IRQ x86, irq: Use helpers to access irq_cfg data structure associated with IRQ x86, irq: Make MSI and HT_IRQ indepenent of X86_IO_APIC x86, irq: Move IRQ initialization routines from io_apic.c into vector.c x86, irq: Move IOAPIC related declarations from hw_irq.h into io_apic.h x86, irq: Move HT IRQ related code from io_apic.c into htirq.c x86, irq: Move PCI MSI related code from io_apic.c into msi.c x86, irq: Replace printk(KERN_LVL) with pr_lvl() utilities x86, irq: Make UP version of irq_complete_move() an inline stub x86, irq: Move local APIC related code from io_apic.c into vector.c x86, irq: Introduce helpers to access struct irq_cfg x86, irq: Protect __clear_irq_vector() with vector_lock x86, irq: Rename local APIC related functions in io_apic.c as apic_xxx() x86, irq: Refine hw_irq.h to prepare for irqdomain support x86, irq: Convert irq_2_pin list to generic list x86, irq: Kill useless parameter 'irq_attr' of IO_APIC_get_PCI_irq_vector() x86, irq, acpi: Get rid of special handling of GSI for ACPI SCI x86, irq: Introduce helper to check whether an IOAPIC has been registered ... 19 December 2014, 22:02:02 UTC

a5fd973 Thomas Gleixner 18 December 2014, 10:51:01 UTC tick/powerclamp: Remove tick_nohz_idle abuse commit 4dbd27711cd9 "tick: export nohz tick idle symbols for module use" was merged via the thermal tree without an explicit ack from the relevant maintainers. The exports are abused by the intel powerclamp driver which implements a fake idle state from a sched FIFO task. This causes all kinds of wreckage in the NOHZ core code which rightfully assumes that tick_nohz_idle_enter/exit() are only called from the idle task itself. Recent changes in the NOHZ core lead to a failure of the powerclamp driver and now people try to hack completely broken and backwards workarounds into the NOHZ core code. This is completely unacceptable and just papers over the real problem. There are way more subtle issues lurking around the corner. The real solution is to fix the powerclamp driver by rewriting it with a sane concept, but that's beyond the scope of this. So the only solution for now is to remove the calls into the core NOHZ code from the powerclamp trainwreck along with the exports.

There will be one more "CONFIG_PM_RUNTIME removal" batch after this one, because some new uses of it have been introduced during the current merge window, but that should be sufficient to finally get rid of it. - Make the ACPI EC driver more robust against race conditions related to GPE handler installation failures (Lv Zheng). - Prevent the ACPI device PM core code from attempting to disable GPEs that it has not enabled which confuses ACPICA and makes it report errors unnecessarily (Rafael J Wysocki). - Add a "force" command line switch to the intel_pstate driver to make it possible to override the blacklisting of some systems in that driver if needed (Ethan Zhao). - Improve intel_pstate code documentation and add a MAINTAINERS entry for it (Kristen Carlson Accardi). - Make the ACPI fan driver create cooling device interfaces witn names that reflect the IDs of the ACPI device objects they are associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B").

For example: Current functions: void zs_init() { } static void get_maxobj_per_zspage() { } Then I want to add a func_1() which is called from zs_init(), and this new added function func_1() will used get_maxobj_per_zspage() which is defined below zs_init(). void func_1() { get_maxobj_per_zspage() } void zs_init() { func_1() } static void get_maxobj_per_zspage() { } This will cause compiling issue. So we must add a declaration: static void get_maxobj_per_zspage(); before func_1() if we do not put get_maxobj_per_zspage() before func_1(). In addition, puting module_[init|exit] functions at the bottom of the file conforms to our habit. So, this patch ajusts function sequence as: /* helper functions */ ... obj_location_to_handle() ... /* Some exported functions */ ... zs_map_object() zs_unmap_object() zs_malloc() zs_free() zs_init() zs_exit() Signed-off-by: Ganesh Mahendran <opensource.ganesh@gmail.com> Cc: Nitin Gupta <ngupta@vflare.org> Acked-by: Minchan Kim <minchan@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 19 December 2014, 03:08:11 UTC
136f49b Junxiao Bi 19 December 2014, 00:17:37 UTC ocfs2: fix journal commit deadlock For buffer write, page lock will be got in write_begin and released in write_end, in ocfs2_write_end_nolock(), before it unlock the page in ocfs2_free_write_ctxt(), it calls ocfs2_run_deallocs(), this will ask for the read lock of journal->j_trans_barrier. Holding page lock and ask for journal->j_trans_barrier breaks the locking order. This will cause a deadlock with journal commit threads, ocfs2cmt will get write lock of journal->j_trans_barrier first, then it wakes up kjournald2 to do the commit work, at last it waits until done. To commit journal, kjournald2 needs flushing data first, it needs get the cache page lock. Since some ocfs2 cluster locks are holding by write process, this deadlock may hung the whole cluster. unlock pages before ocfs2_run_deallocs() can fix the locking order, also put unlock before ocfs2_commit_trans() to make page lock is unlocked before j_trans_barrier to preserve unlocking order.

f62f12b Junxiao Bi 19 December 2014, 00:17:32 UTC ocfs2: reflink: fix slow unlink for refcounted file When running ocfs2 test suite multiple nodes reflink stress test, for a 4 nodes cluster, every unlink() for refcounted file needs about 700s. The slow unlink is caused by the contention of refcount tree lock since all nodes are unlink files using the same refcount tree. When the unlinking file have many extents(over 1600 in our test), most of the extents has refcounted flag set. In ocfs2_commit_truncate(), it will execute the following call trace for every extents. This means it needs get and released refcount tree lock about 1600 times. And when several nodes are do this at the same time, the performance will be very low. ocfs2_remove_btree_range() -- ocfs2_lock_refcount_tree() ---- ocfs2_refcount_lock() ------ __ocfs2_cluster_lock() ocfs2_refcount_lock() is costly, move it to ocfs2_commit_truncate() to do lock/unlock once can improve a lot performance.

With this patch we are showing the CMA info as part of meminfo, so that it can be determined at any point of time. This will be populated only when CMA is enabled.

e48322a Pintu Kumar 19 December 2014, 00:17:15 UTC mm: cma: split cma-reserved in dmesg log When the system boots up, in the dmesg logs we can see the memory statistics along with total reserved as below. Memory: 458840k/458840k available, 65448k reserved, 0K highmem When CMA is enabled, still the total reserved memory remains the same. However, the CMA memory is not considered as reserved. But, when we see /proc/meminfo, the CMA memory is part of free memory. This creates confusion. This patch corrects the problem by properly subtracting the CMA reserved memory from the total reserved memory in dmesg logs. Below is the dmesg snapshot from an arm based device with 512MB RAM and 12MB single CMA region.

If an attempt to create a longname(>255) file/directory is made, it succeeds by creating a file/directory with HFSPLUS_MAX_STRLEN and incorrect catalog key. Thus leaving the volume in an inconsistent state. This patch fixes this issue. Although lookup is always called first to create a negative entry, so just doing a check in lookup would probably fix this issue. I choose to propagate error to other iops as well. Please NOTE: I have factored out hfsplus_cat_build_key_with_cnid from hfsplus_cat_build_key, to avoid unncessary branching. Thanks a lot.

Biederman 18 December 2014, 16:57:19 UTC mnt: Fix a memory stomp in umount While reviewing the code of umount_tree I realized that when we append to a preexisting unmounted list we do not change pprev of the former first item in the list. Which means later in namespace_unlock hlist_del_init(&mnt->mnt_hash) on the former first item of the list will stomp unmounted.first leaving it set to some random mount point which we are likely to free soon. This isn't likely to hit, but if it does I don't know how anyone could track it down. [ This happened because we don't have all the same operations for hlist's as we do for normal doubly-linked lists. In particular, list_splice() is easy on our standard doubly-linked lists, while hlist_splice() doesn't exist and needs both start/end entries of the hlist. And commit 38129a13e6e7 incorrectly open-coded that missing hlist_splice(). We should think about making these kinds of "mindless" conversions easier to get right by adding the missing hlist helpers - Linus ] Fixes: 38129a13e6e71f666e0468e99fdd932a687b4d7e switch mnt_hash to hlist Cc: stable@vger.kernel.org Signed-off-by: "Eric W.

26c0e10 David Vrabel 18 December 2014, 11:13:06 UTC xen-netback: support frontends without feature-rx-notify again Commit bc96f648df1bbc2729abbb84513cf4f64273a1f1 (xen-netback: make feature-rx-notify mandatory) incorrectly assumed that there were no frontends in use that did not support this feature. But the frontend driver in MiniOS does not and since this is used by (qemu) stubdoms, these stopped working. Netback sort of works as-is in this mode except: - If there are no Rx requests and the internal Rx queue fills, only the drain timeout will wake the thread. The default drain timeout of 10 s would give unacceptable pauses. - If an Rx stall was detected and the internal Rx queue is drained, then the Rx thread would never wake. Handle these two cases (when feature-rx-notify is disabled) by: - Reducing the drain timeout to 30 ms. - Disabling Rx stall detection.

66d0f7e Andreas Larsson 18 December 2014, 12:23:23 UTC sparc32: destroy_context() and switch_mm() needs to disable interrupts. Load balancing can be triggered in the critical sections protected by srmmu_context_spinlock in destroy_context() and switch_mm() and can hang the cpu waiting for the rq lock of another cpu that in turn has called switch_mm hangning on srmmu_context_spinlock leading to deadlock. So, disable interrupt while taking srmmu_context_spinlock in destroy_context() and switch_mm() so we don't deadlock.

Currently, searching for a socket to add a reference to is not synchronized with deletion of sockets. This can result in use after free if there is another operation that is removing a socket at the same time. Solving this requires both holding the appropriate lock and checking the refcount to ensure that it has not already hit zero.

a18e6a1 Thomas Graf 18 December 2014, 10:30:26 UTC netlink: Don't reorder loads/stores before marking mmap netlink frame as available Each mmap Netlink frame contains a status field which indicates whether the frame is unused, reserved, contains data or needs to be skipped. Both loads and stores may not be reordeded and must complete before the status field is changed and another CPU might pick up the frame for use. Use an smp_mb() to cover needs of both types of callers to netlink_set_status(), callers which have been reading data frame from the frame, and callers which have been filling or releasing and thus writing to the frame. - Example code path requiring a smp_rmb(): memcpy(skb->data, (void *)hdr + NL_MMAP_HDRLEN, hdr->nm_len); netlink_set_status(hdr, NL_MMAP_STATUS_UNUSED); - Example code path requiring a smp_wmb(): hdr->nm_uid = from_kuid(sk_user_ns(sk), NETLINK_CB(skb).creds.uid); hdr->nm_gid = from_kgid(sk_user_ns(sk), NETLINK_CB(skb).creds.gid); netlink_frame_flush_dcache(hdr); netlink_set_status(hdr, NL_MMAP_STATUS_VALID); Fixes: f9c228 ("netlink: implement memory mapped recvmsg()") Reported-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.
