Pull libnvdimm fixes from Dan Williams: "A small batch of fixes for v4.20-rc3. The overflow continuation fix addresses something that has been broken for several releases. Arguably it could wait even longer, but it's a one line fix and this finishes the last of the known address range scrub bug reports. The revert addresses a lockdep regression. The unit tests are not critical to fix, but no reason to hold this fix back. Summary: - Address Range Scrub overflow continuation handling has been broken since it was initially merged. It was only recently that error injection and platform-BIOS support enabled this corner case to be exercised. - The recent attempt to provide more isolation for the kernel Address Range Scrub state machine from userapace initiated sessions triggers a lockdep report.

Pull ARM spectre updates from Russell King: "These are the currently known final bits that resolve the Spectre issues. big.Little systems used to be sufficiently identical in that there were no differences between individual CPUs in the system that mattered to the kernel. With the advent of the Spectre problem, the CPUs now have differences in how the workaround is applied. As a result of previous Spectre patches, these systems ended up reporting quite a lot of: "CPUx: Spectre v2: incorrect context switching function, system vulnerable" messages due to the action of the big.Little switcher causing the CPUs to be re-initialised regularly. This series resolves that issue by making the CPU vtable unique to each CPU. However, since this is used very early, before per-cpu is setup, per-cpu can't be used. We also have a problem that two of the methods are not called from preempt-safe paths, but thankfully these remain identical between all CPUs in the system. To make sure, we validate that these are identical during boot" * 'spectre' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: spectre-v2: per-CPU vtables to work around big.Little systems ARM: add PROC_VTABLE and PROC_TABLE macros ARM: clean up per-processor check_bugs method call ARM: split out processor lookup ARM: make lookup_processor_type() non-__init -

Other filesystems such as ext4, f2fs and ubifs all return ENXIO when lseek (SEEK_DATA or SEEK_HOLE) requests a negative offset. man 2 lseek says : EINVAL whence is not valid. Or: the resulting file offset would be : negative, or beyond the end of a seekable device. : : ENXIO whence is SEEK_DATA or SEEK_HOLE, and the file offset is beyond : the end of the file. Make tmpfs return ENXIO under these circumstances as well. After this, tmpfs also passes xfstests's generic/448.

Scan through the whole array to see if an update is needed. While we're at it, use sizeof() to be safe against any possible type changes in the future. The bug here is that we wouldn't sync per-cpu counters into global ones if there was an update of numa_stats for higher cpus. Highly theoretical one though because it is much more probable that zone_stats are updated so we would refresh anyway. So I wouldn't bother to mark this for stable, yet something nice to fix.

Spock reported that commit 172b06c3 ("mm: slowly shrink slabs with a relatively small number of objects") leads to a regression on his setup: periodically the majority of the pagecache is evicted without an obvious reason, while before the change the amount of free memory was balancing around the watermark. The reason behind is that the mentioned above change created some minimal background pressure on the inode cache. The problem is that if an inode is considered to be reclaimed, all belonging pagecache page are stripped, no matter how many of them are there. So, if a huge multi-gigabyte file is cached in the memory, and the goal is to reclaim only few slab objects (unused inodes), we still can eventually evict all gigabytes of the pagecache at once. The workload described by Spock has few large non-mapped files in the pagecache, so it's especially noticeable. To solve the problem let's postpone the reclaim of inodes, which have more than 1 attached page. Let's wait until the pagecache pages will be evicted naturally by scanning the corresponding LRU lists, and only then reclaim the inode structure.

Page state checks are racy. Under a heavy memory workload (e.g. stress -m 200 -t 2h) it is quite easy to hit a race window when the page is allocated but its state is not fully populated yet. A debugging patch to dump the struct page state shows has_unmovable_pages: pfn:0x10dfec00, found:0x1, count:0x0 page:ffffea0437fb0000 count:1 mapcount:1 mapping:ffff880e05239841 index:0x7f26e5000 compound_mapcount: 1 flags: 0x5fffffc0090034(uptodate|lru|active|head|swapbacked) Note that the state has been checked for both PageLRU and PageSwapBacked already. Closing this race completely would require some sort of retry logic. This can be tricky and error prone (think of potential endless or long taking loops). Workaround this problem for movable zones at least. Such a zone should only contain movable pages. Commit 15c30bc0 ("mm, memory_hotplug: make has_unmovable_pages more robust") has told us that this is not strictly true though. Bootmem pages should be marked reserved though so we can move the original check after the PageReserved check. Pages from other zones are still prone to races but we even do not pretend that memory hotremove works for those so pre-mature failure doesn't hurt that much.

This bug has been experienced several times by the Oracle DB team. The BUG is in remove_inode_hugepages() as follows: /* * If page is mapped, it was faulted in after being * unmapped in caller. Unmap (again) now after taking * the fault mutex. The mutex will prevent faults * until we finish removing the page. * * This race can only happen in the hole punch case. * Getting here in a truncate operation is a bug. */ if (unlikely(page_mapped(page))) { BUG_ON(truncate_op); In this case, the elevated map count is not the result of a race. Rather it was incorrectly incremented as the result of a bug in the huge pmd sharing code. Consider the following: - Process A maps a hugetlbfs file of sufficient size and alignment (PUD_SIZE) that a pmd page could be shared. - Process B maps the same hugetlbfs file with the same size and alignment such that a pmd page is shared. - Process B then calls mprotect() to change protections for the mapping with the shared pmd. As a result, the pmd is 'unshared'. - Process B then calls mprotect() again to chage protections for the mapping back to their original value. pmd remains unshared. - Process B then forks and process C is created. During the fork process, we do dup_mm -> dup_mmap -> copy_page_range to copy page tables. Copying page tables for hugetlb mappings is done in the routine copy_hugetlb_page_range. In copy_hugetlb_page_range(), the destination pte is obtained by: dst_pte = huge_pte_alloc(dst, addr, sz); If pmd sharing is possible, the returned pointer will be to a pte in an existing page table. In the situation above, process C could share with either process A or process B. Since process A is first in the list, the returned pte is a pointer to a pte in process A's page table. However, the check for pmd sharing in copy_hugetlb_page_range is: /* If the pagetables are shared don't copy or take references */ if (dst_pte == src_pte) continue; Since process C is sharing with process A instead of process B, the above test fails. The code in copy_hugetlb_page_range which follows assumes dst_pte points to a huge_pte_none pte. It copies the pte entry from src_pte to dst_pte and increments this map count of the associated page. This is how we end up with an elevated map count. To solve, check the dst_pte entry for huge_pte_none. If !none, this implies PMD sharing so do not copy.

Reclaim and free can race on an object which is basically fine but in order for reclaim to be able to map "freed" object we need to encode object length in the handle. handle_to_chunks() is then introduced to extract object length from a handle and use it during mapping. Moreover, to avoid racing on a z3fold "headless" page release, we should not try to free that page in z3fold_free() if the reclaim bit is set. Also, in the unlikely case of trying to reclaim a page being freed, we should not proceed with that page. While at it, fix the page accounting in reclaim function. This patch supersedes "[PATCH] z3fold: fix reclaim lock-ups". Link: http://lkml.kernel.org/r/20181105162225.74e8837d03583a9b707cf559@gmail.comSigned-off-by:

GFS2 passes the inode buffer head (dibh) from gfs2_iomap_begin to gfs2_iomap_end in iomap->private. It sets that private pointer in gfs2_iomap_get. Users of gfs2_iomap_get other than gfs2_iomap_begin would have to release iomap->private, but this isn't done correctly, leading to a leak of buffer head references. To fix this, move the code for setting iomap->private from gfs2_iomap_get to gfs2_iomap_begin.

Pull powerpc fixes from Michael Ellerman: "Two weeks worth of fixes since rc1. - I broke 16-byte alignment of the stack when we moved PPR into pt_regs. Despite being required by the ABI this broke almost nothing, we eventually hit it in code where GCC does arithmetic on the stack pointer assuming the bottom 4 bits are clear. Fix it by padding the in-kernel pt_regs by 8 bytes. - A couple of commits fixing minor bugs in the recent SLB rewrite. - A build fix related to tracepoints in KVM in some configurations. - Our old "IO workarounds" code written for Cell couldn't coexist in a kernel that runs on Power9 with the Radix MMU, fix that. - Remove the NPU DMA ops, these just printed a warning and should never have been called. - Suppress an overly chatty message triggered by CPU hotplug in some configs. - Two small selftest fixes.
