Merge mmu_notifier fixes from Jérôme Glisse: "The invalidate_page callback suffered from 2 pitfalls. First it used to happen after page table lock was release and thus a new page might have been setup for the virtual address before the call to invalidate_page(). This is in a weird way fixed by commit c7ab0d2f ("mm: convert try_to_unmap_one() to use page_vma_mapped_walk()") which moved the callback under the page table lock. Which also broke several existing user of the mmu_notifier API that assumed they could sleep inside this callback. The second pitfall was invalidate_page being the only callback not taking a range of address in respect to invalidation but was giving an address and a page. Lot of the callback implementer assumed this could never be THP and thus failed to invalidate the appropriate range for THP pages. By killing this callback we unify the mmu_notifier callback API to always take a virtual address range as input. There is now two clear API (I am not mentioning the youngess API which is seldomly used): - invalidate_range_start()/end() callback (which allow you to sleep) - invalidate_range() where you can not sleep but happen right after page table update under page table lock Note that a lot of existing user feels broken in respect to range_start/ range_end. Many user only have range_start() callback but there is nothing preventing them to undo what was invalidated in their range_start() callback after it returns but before any CPU page table update take place. The code pattern use in kvm or umem odp is an example on how to properly avoid such race. In a nutshell use some kind of sequence number and active range invalidation counter to block anything that might undo what the range_start() callback did. If you do not care about keeping fully in sync with CPU page table (ie you can live with CPU page table pointing to new different page for a given virtual address) then you can take a reference on the pages inside the range_start callback and drop it in range_end or when your driver is done with those pages. Last alternative is to use invalidate_range() if you can do invalidation without sleeping as invalidate_range() callback happens under the CPU page table spinlock right after the page table is updated. The first two patches convert existing mmu_notifier_invalidate_page() calls to mmu_notifier_invalidate_range() and bracket those call with call to mmu_notifier_invalidate_range_start()/end(). The next ten patches remove existing invalidate_page() callback as it can no longer happen. Finally the last page remove the invalidate_page() callback completely so it can RIP. Changes since v1: - remove more dead code in kvm (no testing impact) - more accurate end address computation (patch 2) in page_mkclean_one and try_to_unmap_one - added tested-by/reviewed-by gotten so far" * emailed patches from Jérôme Glisse <jglisse@redhat.com>: mm/mmu_notifier: kill invalidate_page KVM: update to new mmu_notifier semantic v2 xen/gntdev: update to new mmu_notifier semantic sgi-gru: update to new mmu_notifier semantic misc/mic/scif: update to new mmu_notifier semantic iommu/intel: update to new mmu_notifier semantic iommu/amd: update to new mmu_notifier semantic IB/hfi1: update to new mmu_notifier semantic IB/umem: update to new mmu_notifier semantic drm/amdgpu: update to new mmu_notifier semantic powerpc/powernv: update to new mmu_notifier semantic mm/rmap: update to new mmu_notifier semantic v2 dax: update to new mmu_notifier semantic

dtc uses an incorrect format specifier for printing a uint64_t value. uint64_t may be either 'unsigned long' or 'unsigned long long' depending on the host architecture. Fix this by using %llx and casting to unsigned long long, which ensures that we always have a wide enough variable to print 64 bits of hex.

Commit c7acec71 ("kernel.h: handle pointers to arrays better in container_of()") made use of __compiletime_assert() from container_of() thus increasing the usage of this macro, allowing developers to notice type conflicts in usage of container_of() at compile time. However, the implementation of __compiletime_assert relies on compiler optimizations to report an error. This means that if a developer uses "-O0" with any code that performs container_of(), the compiler will always report an error regardless of whether there is an actual problem in the code. This patch disables compile_time_assert when optimizations are disabled to allow such code to compile with CFLAGS="-O0". Example compilation failure: ./include/linux/compiler.h:547:38: error: call to `__compiletime_assert_94' declared with attribute error: pointer type mismatch in container_of() _compiletime_assert(condition, msg, __compiletime_assert_, __LINE__) ^ ./include/linux/compiler.h:530:4: note: in definition of macro `__compiletime_assert' prefix ## suffix(); \ ^~~~~~ ./include/linux/compiler.h:547:2: note: in expansion of macro `_compiletime_assert' _compiletime_assert(condition, msg, __compiletime_assert_, __LINE__) ^~~~~~~~~~~~~~~~~~~ ./include/linux/build_bug.h:46:37: note: in expansion of macro `compiletime_assert' #define BUILD_BUG_ON_MSG(cond, msg) compiletime_assert(!(cond), msg) ^~~~~~~~~~~~~~~~~~ ./include/linux/kernel.h:860:2: note: in expansion of macro `BUILD_BUG_ON_MSG' BUILD_BUG_ON_MSG(!__same_type(*(ptr), ((type *)0)->member) && \ ^~~~~~~~~~~~~~~~ [akpm@linux-foundation.org: use do{}while(0), per Michal] Link: http://lkml.kernel.org/r/20170829230114.11662-1-joe@ovn.org Fixes: c7acec71 ("kernel.h: handle pointers to arrays better in container_of()") Signed-off-by: NJoe Stringer <joe@ovn.org> Cc: Ian Abbott <abbotti@mev.co.uk> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Michal Nazarewicz <mina86@mina86.com> Cc: Kees Cook <keescook@chromium.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Wendy Wang reported off-list that a RAS HWPOISON-SOFT test case failed and bisected it to the commit 479f854a ("mm, page_alloc: defer debugging checks of pages allocated from the PCP"). The problem is that a page that was poisoned with madvise() is reused. The commit removed a check that would trigger if DEBUG_VM was enabled but re-enabling the check only fixes the problem as a side-effect by printing a bad_page warning and recovering. The root of the problem is that an madvise() can leave a poisoned page on the per-cpu list. This patch drains all per-cpu lists after pages are poisoned so that they will not be reused. Wendy reports that the test case in question passes with this patch applied. While this could be done in a targeted fashion, it is over-complicated for such a rare operation.

Commit 7c051267 ("mm, fork: make dup_mmap wait for mmap_sem for write killable") made it possible to kill a forking task while it is waiting to acquire its ->mmap_sem for write, in dup_mmap(). However, it was overlooked that this introduced an new error path before the new mm_struct's ->uprobes_state.xol_area has been set to NULL after being copied from the old mm_struct by the memcpy in dup_mm(). For a task that has previously hit a uprobe tracepoint, this resulted in the 'struct xol_area' being freed multiple times if the task was killed at just the right time while forking. Fix it by setting ->uprobes_state.xol_area to NULL in mm_init() rather than in uprobe_dup_mmap(). With CONFIG_UPROBE_EVENTS=y, the bug can be reproduced by the same C program given by commit 2b7e8665 ("fork: fix incorrect fput of ->exe_file causing use-after-free"), provided that a uprobe tracepoint has been set on the fork_thread() function. For example: $ gcc reproducer.c -o reproducer -lpthread $ nm reproducer | grep fork_thread 0000000000400719 t fork_thread $ echo "p $PWD/reproducer:0x719" > /sys/kernel/debug/tracing/uprobe_events $ echo 1 > /sys/kernel/debug/tracing/events/uprobes/enable $ ./reproducer Here is the use-after-free reported by KASAN: BUG: KASAN: use-after-free in uprobe_clear_state+0x1c4/0x200 Read of size 8 at addr ffff8800320a8b88 by task reproducer/198 CPU: 1 PID: 198 Comm: reproducer Not tainted 4.13.0-rc7-00015-g36fde05f #255 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-20170228_101828-anatol 04/01/2014 Call Trace: dump_stack+0xdb/0x185 print_address_description+0x7e/0x290 kasan_report+0x23b/0x350 __asan_report_load8_noabort+0x19/0x20 uprobe_clear_state+0x1c4/0x200 mmput+0xd6/0x360 do_exit+0x740/0x1670 do_group_exit+0x13f/0x380 get_signal+0x597/0x17d0 do_signal+0x99/0x1df0 exit_to_usermode_loop+0x166/0x1e0 syscall_return_slowpath+0x258/0x2c0 entry_SYSCALL_64_fastpath+0xbc/0xbe ...

But since slab shrinker functions might indirectly wait for other thread's __GFP_DIRECT_RECLAIM && !__GFP_NORETRY memory allocations via sleeping locks, calling slab shrinker functions from node_reclaim() from get_page_from_freelist() with oom_lock held has possibility of deadlock.

Replace all mmu_notifier_invalidate_page() calls by *_invalidate_range() and make sure it is bracketed by calls to *_invalidate_range_start()/end(). Note that because we can not presume the pmd value or pte value we have to assume the worst and unconditionaly report an invalidation as happening.

A 31-bit compat process can force a BUG_ON in crst_table_upgrade with specific, invalid mmap calls, e.g. mmap((void*) 0x7fff8000, 0x10000, 3, 32, -1, 0) The arch_get_unmapped_area[_topdown] functions miss an if condition in the decision to do a page table upgrade.

Pull libnvdimm fix from Dan Williams: "A single patch removing some structure definitions from a uapi header file. These payloads are never processed directly by the kernel they are simply passed through an ioctl as opaque blobs to the ACPI _DSM (Device Specific Method) interface. Userspace should not be depending on the kernel to define these payloads. We will instead provide these definitions via the existing libndctl (https://github.com/pmem/ndctl) project that has NVDIMM command helpers and other definitions" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: libnvdimm: clean up command definitions

Currently the maximum size of SMB2/3 header is set incorrectly which leads to hanging of directory listing operations on encrypted SMB3 connections. Fix this by setting the maximum size to 170 bytes that is calculated as RFC1002 length field size (4) + transform header size (52) + SMB2 header size (64) + create response size (56).
