2018-10-26mm: don't warn about large allocations for slabDmitry Vyukov
Slub does not call kmalloc_slab() for sizes > KMALLOC_MAX_CACHE_SIZE, instead it falls back to kmalloc_large(). For slab KMALLOC_MAX_CACHE_SIZE == KMALLOC_MAX_SIZE and it calls kmalloc_slab() for all allocations relying on NULL return value for over-sized allocations. This inconsistency leads to unwanted warnings from kmalloc_slab() for over-sized allocations for slab. Returning NULL for failed allocations is the expected behavior. Make slub and slab code consistent by checking size > KMALLOC_MAX_CACHE_SIZE in slab before calling kmalloc_slab(). While we are here also fix the check in kmalloc_slab(). We should check against KMALLOC_MAX_CACHE_SIZE rather than KMALLOC_MAX_SIZE. It all kinda worked because for slab the constants are the same, and slub always checks the size against KMALLOC_MAX_CACHE_SIZE before kmalloc_slab(). But if we get there with size > KMALLOC_MAX_CACHE_SIZE anyhow bad things will happen. For example, in case of a newly introduced bug in slub code. Also move the check in kmalloc_slab() from function entry to the size > 192 case. This partially compensates for the additional check in slab code and makes slub code a bit faster (at least theoretically). Also drop __GFP_NOWARN in the warning check. This warning means a bug in slab code itself, user-passed flags have nothing to do with it. Nothing of this affects slob.

ARM64 has asm implementation of memchr(), memcmp(), str[r]chr(), str[n]cmp(), str[n]len(). KASAN don't see memory accesses in asm code, thus it can potentially miss many bugs. Ifdef out __HAVE_ARCH_* defines of these functions when KASAN is enabled, so the generic implementations from lib/string.c will be used. We can't just remove the asm functions because efistub uses them. And we can't have two non-weak functions either, so declare the asm functions as weak.

2018-10-26include/linux/pfn_t.h: force '~' to be parsed as an unary operatorSebastien Boisvert
Tracing the event "fs_dax:dax_pmd_insert_mapping" with perf produces this warning: [fs_dax:dax_pmd_insert_mapping] unknown op '~' It is printed in process_op (tools/lib/traceevent/event-parse.c) because '~' is parsed as a binary operator. perf reads the format of fs_dax:dax_pmd_insert_mapping ("print fmt") from /sys/kernel/debug/tracing/events/fs_dax/dax_pmd_insert_mapping/format . The format contains: ~(((u64) ~(~(((1UL) << 12)-1))) ^ \ interpreted as a binary operator by process_op(). This part is generated in the declaration of the event class dax_pmd_insert_mapping_class in include/trace/events/fs_dax.h : __print_flags_u64(__entry->pfn_val & PFN_FLAGS_MASK, "|", PFN_FLAGS_TRACE), This patch adds a pair of parentheses in the declaration of PFN_FLAGS_MASK to make sure that '~' is parsed as a unary operator by perf. The part of the format that was problematic is now: ~(((u64) (~(~(((1UL) << 12)-1)))) Now, all the '~' are parsed as unary operators.

userfaultfd contains howe-grown locking of the waitqueue lock, and does not disable interrupts. This relies on the fact that no one else takes it from interrupt context and violates an invariat of the normal waitqueue locking scheme. With aio poll it is easy to trigger other locks that disable interrupts (or are called from interrupt context).

It's really time to get this into a regression test somewhere so I stop breaking it. Thanks to Zong for resurrecting it again! - Various fixes that resulted from a year old review of our original patch set that I finally got around to. - Various improvements to SMP support, largely based around having switched to logical hart numbering, as well as some interrupt improvements. This one is in the same patch set as above, thanks to Atish for sheparding everything though as my patch set was a bit of a mess. I'm pretty sure this is our largest patch set since the original kernel contribution, and it's certainly the one with the most contributors.

Older versions of bintutils do not allow symbol math across different segments on sparc: ==================== Assembler messages: 99: Error: operation combines symbols in different segments ==================== This is controlled by whether or not DIFF_EXPR_OK is defined in gas/config/tc-*.h and for sparc this was not the case until mid-2017. So we have to patch between %stick and %tick another way. Do what powerpc does and emit two versions of the relevant functions, one using %tick and one using %stick, and patch the symbols in the dynamic symbol table.

FYI, I may be sending another update later in the cycle - there's a pending rework of the clone/dedupe_file_range code that fixes numerous bugs that is spread amongst the VFS, XFS and ocfs2 code. It has been reviewed and tested, Al and I just need to work out the details of the merge, so it may come from him rather than me. Summary: - only support filesystems with unwritten extents - add definition for statfs XFS magic number - remove unused parameters around reflink code - more debug for dangling delalloc extents - cancel COW extents on extent swap targets - fix quota stats output and clean up the code - refactor some of the attribute code in preparation for parent pointers - fix several buffer handling bugs" * tag 'xfs-4.20-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (21 commits) xfs: cancel COW blocks before swapext xfs: clear ail delwri queued bufs on unmount of shutdown fs xfs: use offsetof() in place of offset macros for __xfsstats xfs: Fix xqmstats offsets in /proc/fs/xfs/xqmstat xfs: fix use-after-free race in xfs_buf_rele xfs: Add attibute remove and helper functions xfs: Add attibute set and helper functions xfs: Add helper function xfs_attr_try_sf_addname xfs: Move fs/xfs/xfs_attr.h to fs/xfs/libxfs/xfs_attr.h xfs: issue log message on user force shutdown xfs: fix buffer state management in xrep_findroot_block xfs: always assign buffer verifiers when one is provided xfs: xrep_findroot_block should reject root blocks with siblings xfs: add a define for statfs magic to uapi xfs: print dangling delalloc extents xfs: fix fork selection in xfs_find_trim_cow_extent xfs: remove the unused trimmed argument from xfs_reflink_trim_around_shared xfs: remove the unused shared argument to xfs_reflink_reserve_cow xfs: handle zeroing in xfs_file_iomap_begin_delay xfs: remove suport for filesystems without unwritten extent flag ...
