git://git.kernel.org/pub/scm/linux/kernel/git/glikely/linux Pull devicetree bugfix from Grant Likely: "One more bug fix for v3.18. I debated whether or not to send you this merge request because we're at such a late rc. The bug isn't critical in that there is only one system known to be affected and the patch is easy to backport. The codepath is used by pretty much every DT based system, so there is risk a of regression (it /should/ be safe, but I've been bitten by stuff that should be safe before). I've had it in linux-next for a week and haven't received any complaints. I think it probably should just be merged right away rather than waiting for the merge window and backporting. It does fix a real bug and the code is theoretically safer after the change. I can't think of any situation where it would be dangerous to reserve the DT memory an extra time. Summary from tag: Single bugfix for boot failure seen in the wild. The memory reserve code tries to be clever about reserving the FDT, but it should just go ahead and reserve it unconditionally to avoid the problem of partial overlap described in the patch" * tag 'devicetree-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/glikely/linux: of/fdt: memblock_reserve /memreserve/ regions in the case of partial overlap

2014-12-03slab: fix nodeid bounds check for non-contiguous node IDsPaul Mackerras1-1/+1
The bounds check for nodeid in ____cache_alloc_node gives false positives on machines where the node IDs are not contiguous, leading to a panic at boot time. For example, on a POWER8 machine the node IDs are typically 0, 1, 16 and 17. This means that num_online_nodes() returns 4, so when ____cache_alloc_node is called with nodeid = 16 the VM_BUG_ON triggers, like this: kernel BUG at /home/paulus/kernel/kvm/mm/slab.c:3079! Call Trace: .____cache_alloc_node+0x5c/0x270 (unreliable) .kmem_cache_alloc_node_trace+0xdc/0x360 .init_list+0x3c/0x128 .kmem_cache_init+0x1dc/0x258 .start_kernel+0x2a0/0x568 start_here_common+0x20/0xa8 To fix this, we instead compare the nodeid with MAX_NUMNODES, and additionally make sure it isn't negative (since nodeid is an int). The check is there mainly to protect the array dereference in the get_node() call in the next line, and the array being dereferenced is of size MAX_NUMNODES. If the nodeid is in range but invalid (for example if the node is off-line), the BUG_ON in the next line will catch that.

2014-12-03mm: fix anon_vma_clone() error treatmentDaniel Forrest2-5/+11
Andrew Morton noticed that the error return from anon_vma_clone() was being dropped and replaced with -ENOMEM (which is not itself a bug because the only error return value from anon_vma_clone() is -ENOMEM). I did an audit of callers of anon_vma_clone() and discovered an actual bug where the error return was being lost. In __split_vma(), between Linux 3.11 and 3.12 the code was changed so the err variable is used before the call to anon_vma_clone() and the default initial value of -ENOMEM is overwritten. So a failure of anon_vma_clone() will return success since err at this point is now zero. Below is a patch which fixes this bug and also propagates the error return value from anon_vma_clone() in all cases.

2014-12-03mm: fix swapoff hang after page migration and forkHugh Dickins1-13/+13
I've been seeing swapoff hangs in recent testing: it's cycling around trying unsuccessfully to find an mm for some remaining pages of swap. I have been exercising swap and page migration more heavily recently, and now notice a long-standing error in copy_one_pte(): it's trying to add dst_mm to swapoff's mmlist when it finds a swap entry, but is doing so even when it's a migration entry or an hwpoison entry. Which wouldn't matter much, except it adds dst_mm next to src_mm, assuming src_mm is already on the mmlist: which may not be so. Then if pages are later swapped out from dst_mm, swapoff won't be able to find where to replace them. There's already a !non_swap_entry() test for stats: move that up before the swap_duplicate() and the addition to mmlist.

2014-12-03ipc/sem.c: fully initialize sem_array before making it visibleManfred Spraul1-7/+8
ipc_addid() makes a new ipc identifier visible to everyone. New objects start as locked, so that the caller can complete the initialization after the call. Within struct sem_array, at least sma->sem_base and sma->sem_nsems are accessed without any locks, therefore this approach doesn't work. Thus: Move the ipc_addid() to the end of the initialization.

2014-12-02xen-netfront: Remove BUGs on paged skb data which crosses a page boundarySeth Forshee1-5/+0
These BUGs can be erroneously triggered by frags which refer to tail pages within a compound page. The data in these pages may overrun the hardware page while still being contained within the compound page, but since compound_order() evaluates to 0 for tail pages the assertion fails. The code already iterates through subsequent pages correctly in this scenario, so the BUGs are unnecessary and can be removed.

2014-12-02mm: frontswap: invalidate expired data on a dup-store failureWeijie Yang1-1/+3
If a frontswap dup-store failed, it should invalidate the expired page in the backend, or it could trigger some data corruption issue. Such as: 1. use zswap as the frontswap backend with writeback feature 2. store a swap page(version_1) to entry A, success 3. dup-store a newer page(version_2) to the same entry A, fail 4. use __swap_writepage() write version_2 page to swapfile, success 5. zswap do shrink, writeback version_1 page to swapfile 6. version_2 page is overwrited by version_1, data corrupt. This patch fixes this issue by invalidating expired data immediately when meet a dup-store failure.

2014-12-02block: fix regression where bio_integrity_process uses wrong bio_vec iteratorDarrick J. Wong1-6/+7
bio integrity handling is broken on a system with LVM layered atop a DIF/DIX SCSI drive because device mapper clones the bio, modifies the clone, and sends the clone to the lower layers for processing. However, the clone bio has bi_vcnt == 0, which means that when the sd driver calls bio_integrity_process to attach DIX data, the for_each_segment_all() call (which uses bi_vcnt) returns immediately and random garbage is sent to the disk on a disk write. The disk of course returns an error. Therefore, teach bio_integrity_process() to use bio_for_each_segment() to iterate the bio_vecs, since the per-bio iterator tracks which bio_vecs are associated with that particular bio. The integrity handling code is effectively part of the "driver" (it's not the bio owner), so it must use the correct iterator function. v2: Fix a compiler warning about abandoned local variables. This patch supersedes "block: bio_integrity_process uses wrong bio_vec iterator". Patch applies against 3.18-rc6. Signed-off-by: Darrick J. Wong <[email protected]> Acked-by: Martin K.
