    GRKERNSEC_KMEM is enabled with DEBUG_FS

    Backport fix from: https://patchwork.kernel.org/patch/6853351/
    The debug_read_tlb() uses the sprintf() functions directly on the buffer
    allocated by buf = kmalloc(count), without taking into account the size
    of the buffer, with the consequence corrupting the heap, depending on
    the count requested by the user.
    
    The patch fixes the issue replacing sprintf() by seq_printf().

    ethtool: Use kcalloc instead of kmalloc for ethtool_get_strings
    
    It seems that kernel memory can leak into userspace by a
    kmalloc, ethtool_get_strings, then copy_to_user sequence.
    
    Avoid this by using kcalloc to zero fill the copied buffer.

    tty: fix data race on tty_buffer.commit
    
    Race on buffer data happens when newly committed data is
    picked up by an old flush work in the following scenario:
    __tty_buffer_request_room does a plain write of tail->commit,
    no barriers were executed before that.
    At this point flush_to_ldisc reads this new value of commit,
    and reads buffer data, no barriers in between.
    The committed buffer data is not necessary visible to flush_to_ldisc.
    
    Similar bug happens when tty_schedule_flip commits data.
    
    Update commit with smp_store_release and read commit with
    smp_load_acquire, as it is commit that signals data readiness.
    This is orthogonal to the existing synchronization on tty_buffer.next,
    which is required to not dismiss a buffer with unconsumed data.
    
    The data race was found with KernelThreadSanitizer (KTSAN).

    tty: fix stall caused by missing memory barrier in drivers/tty/n_tty.c
    
    My colleague ran into a program stall on a x86_64 server, where
    n_tty_read() was waiting for data even if there was data in the buffer
    in the pty.  kernel stack for the stuck process looks like below.
     #0 [ffff88303d107b58] __schedule at ffffffff815c4b20
     #1 [ffff88303d107bd0] schedule at ffffffff815c513e
     #2 [ffff88303d107bf0] schedule_timeout at ffffffff815c7818
     #3 [ffff88303d107ca0] wait_woken at ffffffff81096bd2
     #4 [ffff88303d107ce0] n_tty_read at ffffffff8136fa23
     #5 [ffff88303d107dd0] tty_read at ffffffff81368013
     #6 [ffff88303d107e20] __vfs_read at ffffffff811a3704

     #8 [ffff88303d107f00] sys_read at ffffffff811a4306
     #9 [ffff88303d107f50] entry_SYSCALL_64_fastpath at ffffffff815c86d7
    
    There seems to be two problems causing this issue.
    
    First, in drivers/tty/n_tty.c, __receive_buf() stores the data and
    updates ldata->commit_head using smp_store_release() and then checks
    the wait queue using waitqueue_active().  However, since there is no
    memory barrier, __receive_buf() could return without calling
    wake_up_interactive_poll(), and at the same time, n_tty_read() could
    start to wait in wait_woken() as in the following chart.
    
            __receive_buf()                         n_tty_read()
    ------------------------------------------------------------------------
    if (waitqueue_active(&tty->read_wait))
    /* Memory operations issued after the
       RELEASE may be completed before the
       RELEASE operation has completed */
                                            add_wait_queue(&tty->read_wait, &wait);
                                            ...
                                            if (!input_available_p(tty, 0)) {
    smp_store_release(&ldata->commit_head,
                      ldata->read_head);
                                            ...
                                            timeout = wait_woken(&wait,
                                              TASK_INTERRUPTIBLE, timeout);
    ------------------------------------------------------------------------
    
    The second problem is that n_tty_read() also lacks a memory barrier
    call and could also cause __receive_buf() to return without calling
    wake_up_interactive_poll(), and n_tty_read() to wait in wait_woken()
    as in the chart below.
    
            __receive_buf()                         n_tty_read()
    ------------------------------------------------------------------------
                                            spin_lock_irqsave(&q->lock, flags);
                                            /* from add_wait_queue() */
                                            ...

                                              TASK_INTERRUPTIBLE, timeout);
    ------------------------------------------------------------------------
    
    There are also other places in drivers/tty/n_tty.c which have similar
    calls to waitqueue_active(), so instead of adding many memory barrier
    calls, this patch simply removes the call to waitqueue_active(),
    leaving just wake_up*() behind.
    
    This fixes both problems because, even though the memory access before
    or after the spinlocks in both wake_up*() and add_wait_queue() can
    sneak into the critical section, it cannot go past it and the critical
    section assures that they will be serialized (please see "INTER-CPU
    ACQUIRING BARRIER EFFECTS" in Documentation/memory-barriers.txt for a
    better explanation).  Moreover, the resulting code is much simpler.
    
    Latency measurement using a ping-pong test over a pty doesn't show any
    visible performance drop.

    tty: fix data race in flush_to_ldisc
    
    flush_to_ldisc reads port->itty and checks that it is not NULL,
    concurrently release_tty sets port->itty to NULL. It is possible
    that flush_to_ldisc loads port->itty once, ensures that it is
    not NULL, but then reloads it again and uses. The second load
    can already return NULL, which will cause a crash.
    
    Use READ_ONCE to read port->itty.
    
    The data race was found with KernelThreadSanitizer (KTSAN).

    tty: fix data race in tty_buffer_flush
    
    tty_buffer_flush frees not acquired buffers.
    As the result, for example, read of b->size in tty_buffer_free
    can return garbage value which will lead to a huge buffer
    hanging in the freelist. This is just the benignest

    namei: results of d_is_negative() should be checked after dentry revalidation
    
    Leandro Awa writes:
     "After switching to version 4.1.6, our parallelized and distributed
      workflows now fail consistently with errors of the form:
    
      T34: ./regex.c:39:22: error: config.h: No such file or directory
    
      From our 'git bisect' testing, the following commit appears to be the
      possible cause of the behavior we've been seeing: commit 766c4cbfacd8"
    
    Al Viro says:
     "What happens is that 766c4cbfacd8 got the things subtly wrong.
    
      We used to treat d_is_negative() after lookup_fast() as "fall with
      ENOENT".  That was wrong - checking ->d_flags outside of ->d_seq
      protection is unreliable and failing with hard error on what should've
      fallen back to non-RCU pathname resolution is a bug.
    
      Unfortunately, we'd pulled the test too far up and ran afoul of
      another kind of staleness.  The dentry might have been absolutely
      stable from the RCU point of view (and we might be on UP, etc), but
      stale from the remote fs point of view.  If ->d_revalidate() returns
      "it's actually stale", dentry gets thrown away and the original code
      wouldn't even have looked at its ->d_flags.
    
      What we need is to check ->d_flags where 766c4cbfacd8 does (prior to
      ->d_seq validation) but only use the result in cases where we do not
      discard this dentry outright"

    x86/efi: Fix boot crash by mapping EFI memmap entries bottom-up at runtime, instead of top-down
    
    Beginning with UEFI v2.5 EFI_PROPERTIES_TABLE was introduced
    that signals that the firmware PE/COFF loader supports splitting
    code and data sections of PE/COFF images into separate EFI
    memory map entries. This allows the kernel to map those regions
    with strict memory protections, e.g. EFI_MEMORY_RO for code,
    EFI_MEMORY_XP for data, etc.
    
    Unfortunately, an unwritten requirement of this new feature is
    that the regions need to be mapped with the same offsets
    relative to each other as observed in the EFI memory map. If
    this is not done crashes like this may occur,
    
      BUG: unable to handle kernel paging request at fffffffefe6086dd
      IP: [<fffffffefe6086dd>] 0xfffffffefe6086dd
      Call Trace:
       [<ffffffff8104c90e>] efi_call+0x7e/0x100
       [<ffffffff81602091>] ? virt_efi_set_variable+0x61/0x90
       [<ffffffff8104c583>] efi_delete_dummy_variable+0x63/0x70
       [<ffffffff81f4e4aa>] efi_enter_virtual_mode+0x383/0x392

       [<ffffffff81f37495>] x86_64_start_reservations+0x2a/0x2c
       [<ffffffff81f37582>] x86_64_start_kernel+0xeb/0xef
    
    Here 0xfffffffefe6086dd refers to an address the firmware
    expects to be mapped but which the OS never claimed was mapped.
    The issue is that included in these regions are relative
    addresses to other regions which were emitted by the firmware
    toolchain before the "splitting" of sections occurred at
    runtime.
    
    Needless to say, we don't satisfy this unwritten requirement on
    x86_64 and instead map the EFI memory map entries in reverse
    order. The above crash is almost certainly triggerable with any
    kernel newer than v3.13 because that's when we rewrote the EFI
    runtime region mapping code, in commit d2f7cbe7b26a ("x86/efi:
    Runtime services virtual mapping"). For kernel versions before
    v3.13 things may work by pure luck depending on the
    fragmentation of the kernel virtual address space at the time we
    map the EFI regions.
    
    Instead of mapping the EFI memory map entries in reverse order,
    where entry N has a higher virtual address than entry N+1, map
    them in the same order as they appear in the EFI memory map to
    preserve this relative offset between regions.
    
    This patch has been kept as small as possible with the intention
    that it should be applied aggressively to stable and
    distribution kernels. It is very much a bugfix rather than
    support for a new feature, since when EFI_PROPERTIES_TABLE is
    enabled we must map things as outlined above to even boot - we
    have no way of asking the firmware not to split the code/data
    regions.
    
    In fact, this patch doesn't even make use of the more strict
    memory protections available in UEFI v2.5. That will come later.

    arm64/efi: Fix boot crash by not padding between EFI_MEMORY_RUNTIME regions
    
    The new Properties Table feature introduced in UEFIv2.5 may
    split memory regions that cover PE/COFF memory images into
    separate code and data regions. Since these regions only differ
    in the type (runtime code vs runtime data) and the permission
    bits, but not in the memory type attributes (UC/WC/WT/WB), the
    spec does not require them to be aligned to 64 KB.
    
    Since the relative offset of PE/COFF .text and .data segments
    cannot be changed on the fly, this means that we can no longer
    pad out those regions to be mappable using 64 KB pages.
    Unfortunately, there is no annotation in the UEFI memory map
    that identifies data regions that were split off from a code
    region, so we must apply this logic to all adjacent runtime
    regions whose attributes only differ in the permission bits.
    
    So instead of rounding each memory region to 64 KB alignment at
    both ends, only round down regions that are not directly
    preceded by another runtime region with the same type
    attributes. Since the UEFI spec does not mandate that the memory
    map be sorted, this means we also need to sort it first.
    
    Note that this change will result in all EFI_MEMORY_RUNTIME
    regions whose start addresses are not aligned to the OS page
    size to be mapped with executable permissions (i.e., on kernels
    compiled with 64 KB pages). However, since these mappings are
    only active during the time that UEFI Runtime Services are being
    invoked, the window for abuse is rather small.

    MIPS: BPF: Fix load delay slots.
    
    The entire bpf_jit_asm.S is written in noreorder mode because "we know
    better" according to a comment.  This also prevented the assembler from
    throwing in the required NOPs for MIPS I processors which have no
    load-use interlock, thus the load's consumer might end up using the
    old value of the register from prior to the load.
    
    Fixed by putting the assembler in reorder mode for just the affected
    load instructions.  This is not enough for gas to actually try to be
    clever by looking at the next instruction and inserting a nop only
    when needed but as the comment said "we know better", so getting gas
    to unconditionally emit a NOP is just right in this case and prevents
    adding further ifdefery.

    x86/kexec: Fix kexec crash in syscall kexec_file_load()
    
    The original bug is a page fault crash that sometimes happens
    on big machines when preparing ELF headers:
    
        BUG: unable to handle kernel paging request at ffffc90613fc9000
        IP: [<ffffffff8103d645>] prepare_elf64_ram_headers_callback+0x165/0x260
    
    The bug is caused by us under-counting the number of memory ranges
    and subsequently not allocating enough ELF header space for them.
    The bug is typically masked on smaller systems, because the ELF header
    allocation is rounded up to the next page.
    
    This patch modifies the code in fill_up_crash_elf_data() by using
    walk_system_ram_res() instead of walk_system_ram_range() to correctly
    count the max number of crash memory ranges. That's because the
    walk_system_ram_range() filters out small memory regions that
    reside in the same page, but walk_system_ram_res() does not.
    
    Here's how I found the bug:
    
    After tracing prepare_elf64_headers() and prepare_elf64_ram_headers_callback(),
    the code uses walk_system_ram_res() to fill-in crash memory regions information
    to the program header, so it counts those small memory regions that
    reside in a page area.
    
    But, when the kernel was using walk_system_ram_range() in
    fill_up_crash_elf_data() to count the number of crash memory regions,
    it filters out small regions.
    
    I printed those small memory regions, for example:
    
      kexec: Get nr_ram ranges. vaddr=0xffff880077592258 paddr=0x77592258, sz=0xdc0
    
    Based on the code in walk_system_ram_range(), this memory region
    will be filtered out:
    
      pfn = (0x77592258 + 0x1000 - 1) >> 12 = 0x77593
      end_pfn = (0x77592258 + 0xfc0 -1 + 1) >> 12 = 0x77593
      end_pfn - pfn = 0x77593 - 0x77593 = 0  <=== if (end_pfn > pfn) is FALSE
    
    So, the max_nr_ranges that's counted by the kernel doesn't include
    small memory regions - causing us to under-allocate the required space.
    That causes the page fault crash that happens in a later code path
    when preparing ELF headers.
    
    This bug is not easy to reproduce on small machines that have few
    CPUs, because the allocated page aligned ELF buffer has more free
    space to cover those small memory regions' PT_LOAD headers.

    netfilter: conntrack: use nf_ct_tmpl_free in CT/synproxy error paths
    
    Commit 0838aa7fcfcd ("netfilter: fix netns dependencies with conntrack
    templates") migrated templates to the new allocator api, but forgot to
    update error paths for them in CT and synproxy to use nf_ct_tmpl_free()
    instead of nf_conntrack_free().
    
    Due to that, memory is being freed into the wrong kmemcache, but also
    we drop the per net reference count of ct objects causing an imbalance.
    
    In Brad's case, this leads to a wrap-around of net->ct.count and thus
    lets __nf_conntrack_alloc() refuse to create a new ct object:
    
      [   10.340913] xt_addrtype: ipv6 does not support BROADCAST matching
      [   10.810168] nf_conntrack: table full, dropping packet
      [   11.917416] r8169 0000:07:00.0 eth0: link up
      [   11.917438] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
      [   12.815902] nf_conntrack: table full, dropping packet
      [   15.688561] nf_conntrack: table full, dropping packet
      [   15.689365] nf_conntrack: table full, dropping packet
      [   15.690169] nf_conntrack: table full, dropping packet
      [   15.690967] nf_conntrack: table full, dropping packet
      [...]
    
    With slab debugging, it also reports the wrong kmemcache (kmalloc-512 vs.
    nf_conntrack_ffffffff81ce75c0) and reports poison overwrites, etc. Thus,
    to fix the problem, export and use nf_ct_tmpl_free() instead.

    dmapool: fix overflow condition in pool_find_page()
    
    If a DMA pool lies at the very top of the dma_addr_t range (as may
    happen with an IOMMU involved), the calculated end address of the pool
    wraps around to zero, and page lookup always fails.
    
    Tweak the relevant calculation to be overflow-proof.

    memcg: make mem_cgroup_read_stat() unsigned
    
    mem_cgroup_read_stat() returns a page count by summing per cpu page
    counters.  The summing is racy wrt.  updates, so a transient negative
    sum is possible.  Callers don't want negative values:
    
     - mem_cgroup_wb_stats() doesn't want negative nr_dirty or nr_writeback.
       This could confuse dirty throttling.
    
     - oom reports and memory.stat shouldn't show confusing negative usage.
    
     - tree_usage() already avoids negatives.
    
    Avoid returning negative page counts from mem_cgroup_read_stat() and
    convert it to unsigned.

    bpf: fix panic in SO_GET_FILTER with native ebpf programs
    
    When sockets have a native eBPF program attached through
    setsockopt(sk, SOL_SOCKET, SO_ATTACH_BPF, ...), and then try to
    dump these over getsockopt(sk, SOL_SOCKET, SO_GET_FILTER, ...),
    the following panic appears:

    The underlying issue is the very same as in commit b382c0865600
    ("sock, diag: fix panic in sock_diag_put_filterinfo"), that is,
    native eBPF programs don't store an original program since this
    is only needed in cBPF ones.
    
    However, sk_get_filter() wasn't updated to test for this at the
    time when eBPF could be attached. Just throw an error to the user
    to indicate that eBPF cannot be dumped over this interface.
    That way, it can also be known that a program _is_ attached (as
    opposed to just return 0), and a different (future) method needs
    to be consulted for a dump.

    [SMB3] Do not fall back to SMBWriteX in set_file_size error cases
    
    The error paths in set_file_size for cifs and smb3 are incorrect.
    
    In the unlikely event that a server did not support set file info
    of the file size, the code incorrectly falls back to trying SMBWriteX
    (note that only the original core SMB Write, used for example by DOS,
    can set the file size this way - this actually  does not work for the more
    recent SMBWriteX).  The idea was since the old DOS SMB Write could set
    the file size if you write zero bytes at that offset then use that if
    server rejects the normal set file info call.
    
    Fortunately the SMBWriteX will never be sent on the wire (except when
    file size is zero) since the length and offset fields were reversed
    in the two places in this function that call SMBWriteX causing
    the fall back path to return an error. It is also important to never call
    an SMB request from an SMB2/sMB3 session (which theoretically would
    be possible, and can cause a brief session drop, although the client
    recovers) so this should be fixed.  In practice this path does not happen
    with modern servers but the error fall back to SMBWriteX is clearly wrong.
    
    Removing the calls to SMBWriteX in the error paths in cifs_set_file_size
