2016-11-30mm: fix false-positive WARN_ON() in truncate/invalidate for hugetlbKirill A. Shutemov
Hugetlb pages have ->index in size of the huge pages (PMD_SIZE or PUD_SIZE), not in PAGE_SIZE as other types of pages. This means we cannot user page_to_pgoff() to check whether we've got the right page for the radix-tree index. Let's introduce page_to_index() which would return radix-tree index for given page. We will be able to get rid of this once hugetlb will be switched to multi-order entries.

2016-11-30lib/debugobjects: export for use in modulesChris Wilson
Drivers, or other modules, that use a mixture of objects (especially objects embedded within other objects) would like to take advantage of the debugobjects facilities to help catch misuse. Currently, the debugobjects interface is only available to builtin drivers and requires a set of EXPORT_SYMBOL_GPL for use by modules. I am using the debugobjects in i915.ko to try and catch some invalid operations on embedded objects. The problem currently only presents itself across module unload so forcing i915 to be builtin is not an option.

2016-11-30zram: fix unbalanced idr management at hot removalTakashi Iwai
The zram hot removal code calls idr_remove() even when zram_remove() returns an error (typically -EBUSY). This results in a leftover at the device release, eventually leading to a crash when the module is reloaded. As described in the bug report below, the following procedure would cause an Oops with zram: - provision three zram devices via modprobe zram num_devices=3 - configure a size for each device + echo "1G" > /sys/block/$zram_name/disksize - mkfs and mount zram0 only - attempt to hot remove all three devices + echo 2 > /sys/class/zram-control/hot_remove + echo 1 > /sys/class/zram-control/hot_remove + echo 0 > /sys/class/zram-control/hot_remove - zram0 removal fails with EBUSY, as expected - unmount zram0 - try zram0 hot remove again + echo 0 > /sys/class/zram-control/hot_remove - fails with ENODEV (unexpected) - unload zram kernel module + completes successfully - zram0 device node still exists - attempt to mount /dev/zram0 + mount command is killed + following BUG is encountered BUG: unable to handle kernel paging request at ffffffffa0002ba0 IP: get_disk+0x16/0x50 Oops: 0000 [#1] SMP CPU: 0 PID: 252 Comm: mount Not tainted 4.9.0-rc6 #176 Call Trace: exact_lock+0xc/0x20 kobj_lookup+0xdc/0x160 get_gendisk+0x2f/0x110 __blkdev_get+0x10c/0x3c0 blkdev_get+0x19d/0x2e0 blkdev_open+0x56/0x70 do_dentry_open.isra.19+0x1ff/0x310 vfs_open+0x43/0x60 path_openat+0x2c9/0xf30 do_filp_open+0x79/0xd0 do_sys_open+0x114/0x1e0 SyS_open+0x19/0x20 entry_SYSCALL_64_fastpath+0x13/0x94 This patch adds the proper error check in hot_remove_store() not to call idr_remove() unconditionally.

2016-11-30thp: fix corner case of munlock() of PTE-mapped THPsKirill A. Shutemov
The following program triggers BUG() in munlock_vma_pages_range(): // autogenerated by syzkaller (http://github.com/google/syzkaller) #include <sys/mman.h> int main() { mmap((void*)0x20105000ul, 0xc00000ul, 0x2ul, 0x2172ul, -1, 0); mremap((void*)0x201fd000ul, 0x4000ul, 0xc00000ul, 0x3ul, 0x203f0000ul); return 0; } The test-case constructs the situation when munlock_vma_pages_range() finds PTE-mapped THP-head in the middle of page table and, by mistake, skips HPAGE_PMD_NR pages after that. As result, on the next iteration it hits the middle of PMD-mapped THP and gets upset seeing mlocked tail page. The solution is only skip HPAGE_PMD_NR pages if the THP was mlocked during munlock_vma_page(). It would guarantee that the page is PMD-mapped as we never mlock PTE-mapeed THPs. Fixes: e90309c9f772 ("thp: allow mlocked THP again") Link: http://lkml.kernel.org/r/20161115132703.7s7rrgmwttegcdh4@black.fi.intel.com Signed-off-by: Kirill A.

2016-11-30mm, thp: propagation of conditional compilation in khugepaged.cJérémy Lefaure
Commit b46e756f5e47 ("thp: extract khugepaged from mm/huge_memory.c") moved code from huge_memory.c to khugepaged.c. Some of this code should be compiled only when CONFIG_SYSFS is enabled but the condition around this code was not moved into khugepaged.c. The result is a compilation error when CONFIG_SYSFS is disabled: mm/built-in.o: In function `khugepaged_defrag_store': khugepaged.c:(.text+0x2d095): undefined reference to `single_hugepage_flag_store' mm/built-in.o: In function `khugepaged_defrag_show': khugepaged.c:(.text+0x2d0ab): undefined reference to `single_hugepage_flag_show' This commit adds the #ifdef CONFIG_SYSFS around the code related to sysfs.

2016-11-30docs-rst: parse-headers.pl: cleanup the documentationMauro Carvalho Chehab
Keeping both rst and in-file documentation in sync can be harsh. So, simplify the script's internal documntation to a bare minimum, and add a mention to the ReST file with its full documentation. This way, a quick help is still available at the command line, while the complete one is maintained at the ReST format. As we won't be using pad2rst anymore, do a cleanup at the ReST file.

drm-next On the userspace side, all the basics are working, and most of glmark2 is working. I've been working through deqp, and I've got a couple more things to fix (but we've gone from 70% to 80+% pass in last day, and current deqp run that is going should pick up another 5-10%). I expect to push the mesa patches today or tomorrow. There are a couple more a5xx related patches to take the gpu out of secure mode (for the devices that come up in secure mode, like the hw I have), but those depend on an scm patch that would come in through another tree. If that can land in the next day or two, there might be a second late pull request for drm/msm. In addition to the new-shiny, there have also been a lot of overlay/ plane related fixes for issues found using drm-hwc2 (in the process of testing/debugging the atomic/kms fence patches), resulting in rework to assign hwpipes to kms planes dynamically (as part of global atomic state) and also handling SMP (fifo) block allocation atomically as part of the ->atomic_check() step.

2016-11-30svcrdma: Remove DMA map accountingChuck Lever
Clean up: sc_dma_used is not required for correct operation. It is simply a debugging tool to report when svcrdma has leaked DMA maps. However, manipulating an atomic has a measurable CPU cost, and DMA map accounting specific to svcrdma will be meaningless once svcrdma is converted to use the new generic r/w API. A similar kind of debug accounting can be done simply by enabling the IOMMU or by using CONFIG_DMA_API_DEBUG, CONFIG_IOMMU_DEBUG, and CONFIG_IOMMU_LEAK.

2016-11-30svcrdma: Remove BH-disabled spin locking in svc_rdma_send()Chuck Lever
svcrdma's current SQ accounting algorithm takes sc_lock and disables bottom-halves while posting all RDMA Read, Write, and Send WRs. This is relatively heavyweight serialization. And note that Write and Send are already fully serialized by the xpt_mutex. Using a single atomic_t should be all that is necessary to guarantee that ib_post_send() is called only when there is enough space on the send queue. This is what the other RDMA-enabled storage targets do. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
2016-11-30svcrdma: Renovate sendto chunk list parsingChuck Lever
The current sendto code appears to support clients that provide only one of a Read list, a Write list, or a Reply chunk. My reading of that code is that it doesn't support the following cases: - Read list + Write list - Read list + Reply chunk - Write list + Reply chunk - Read list + Write list + Reply chunk The protocol allows more than one Read or Write chunk in those lists. Some clients do send a Read list and Reply chunk simultaneously. NFSv4 WRITE uses a Read list for the data payload, and a Reply chunk because the GETATTR result in the reply can contain a large object like an ACL. Generalize one of the sendto code paths needed to support all of the above cases, and attempt to ensure that only one pass is done through the RPC Call's transport header to gather chunk list information for building the reply.

2016-11-30svcauth_gss: Close connection when dropping an incoming messageChuck Lever
S5.3.3.1 of RFC 2203 requires that an incoming GSS-wrapped message whose sequence number lies outside the current window is dropped. The rationale is: The reason for discarding requests silently is that the server is unable to determine if the duplicate or out of range request was due to a sequencing problem in the client, network, or the operating system, or due to some quirk in routing, or a replay attack by an intruder. Discarding the request allows the client to recover after timing out, if indeed the duplication was unintentional or well intended. However, clients may rely on the server dropping the connection to indicate that a retransmit is needed. Without a connection reset, a client can wait forever without retransmitting, and the workload just stops dead. I've reproduced this behavior by running xfstests generic/323 on an NFSv4.0 mount with proto=rdma and sec=krb5i. To address this issue, have the server close the connection when it silently discards an incoming message due to a GSS sequence number problem. There are a few other places where the server will never reply. Change those spots in a similar fashion. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.
