  • arch/tile added word-at-a-time.h after the patch that added generic-y
    entries; the generic-y entry is now stale.

    arch/h8300 is newer than the generic-y patch for word-at-a-time.h,
    and needs a generic-y entry.

    arch/powerpc seems to have gotten a generic-y entry by mistake in
    the first patch; this change removes it.

  • This patch makes sure that atomic_{read,set}() are at least
    {READ,WRITE}_ONCE().

    We already had the 'requirement' that atomic_read() should use
    ACCESS_ONCE(), and most archs had this, but a few were lacking.
    All are now converted to use READ_ONCE().

    And, by a symmetry and general paranoia argument, upgrade atomic_set()
    to use WRITE_ONCE().

  • Almost everyone implements dma_set_mask the same way, although some time
    that's hidden in ->set_dma_mask methods.

    This patch consolidates those into a common implementation that either
    calls ->set_dma_mask if present or otherwise uses the default
    implementation. Some architectures used to only call ->set_dma_mask
    after the initial checks, and those instance have been fixed to do the
    full work. h8300 implemented dma_set_mask bogusly as a no-ops and has
    been fixed.

    Unfortunately some architectures overload unrelated semantics like changing
    the dma_ops into it so we still need to allow for an architecture override
    for now.

  • Most architectures just call into ->dma_supported, but some also return 1
    if the method is not present, or 0 if no dma ops are present (although
    that should never happeb). Consolidate this more broad version into
    common code.

    Also fix h8300 which inorrectly always returned 0, which would have been
    a problem if it's dma_set_mask implementation wasn't a similarly buggy
    noop.

    As a few architectures have much more elaborate implementations, we
    still allow for arch overrides.

  • Currently there are three valid implementations of dma_mapping_error:

    (1) call ->mapping_error
    (2) check for a hardcoded error code
    (3) always return 0

    This patch provides a common implementation that calls ->mapping_error
    if present, then checks for DMA_ERROR_CODE if defined or otherwise
    returns 0.

  • Most architectures do not support non-coherent allocations and either
    define dma_{alloc,free}_noncoherent to their coherent versions or stub
    them out.

    Openrisc uses dma_{alloc,free}_attrs to implement them, and only Mips
    implements them directly.

    This patch moves the Openrisc version to common code, and handles the
    DMA_ATTR_NON_CONSISTENT case in the mips dma_map_ops instance.

    Note that actual non-coherent allocations require a dma_cache_sync
    implementation, so if non-coherent allocations didn't work on
    an architecture before this patch they still won't work after it.

  • Since 2009 we have a nice asm-generic header implementing lots of DMA API
    functions for architectures using struct dma_map_ops, but unfortunately
    it's still missing a lot of APIs that all architectures still have to
    duplicate.

    This series consolidates the remaining functions, although we still need
    arch opt outs for two of them as a few architectures have very
    non-standard implementations.

    This patch (of 5):

    The coherent DMA allocator works the same over all architectures supporting
    dma_map operations.

    This patch consolidates them and converges the minor differences:

    - the debug_dma helpers are now called from all architectures, including
    those that were previously missing them
    - dma_alloc_from_coherent and dma_release_from_coherent are now always
    called from the generic alloc/free routines instead of the ops
    dma-mapping-common.h always includes dma-coherent.h to get the defintions
    for them, or the stubs if the architecture doesn't support this feature
    - checks for ->alloc / ->free presence are removed. There is only one
    magic instead of dma_map_ops without them (mic_dma_ops) and that one
    is x86 only anyway.

    Besides that only x86 needs special treatment to replace a default devices
    if none is passed and tweak the gfp_flags. An optional arch hook is provided
    for that.

  • Commit 2ae416b142b6 ("mm: new mm hook framework") introduced an empty
    header file (mm-arch-hooks.h) for every architecture, even those which
    doesn't need to define mm hooks.

    As suggested by Geert Uytterhoeven, this could be cleaned through the use
    of a generic header file included via each per architecture
    asm/include/Kbuild file.

    The PowerPC architecture is not impacted here since this architecture has
    to defined the arch_remap MM hook.

  • Pull networking updates from David Miller:
    "This is a re-do of the net-next pull request for the current merge
    window. The only difference from the one I made the other day is that
    this has Eliezer's interface renames and the timeout handling changes
    made based upon your feedback, as well as a few bug fixes that have
    trickeled in.

    Highlights:

    1) Low latency device polling, eliminating the cost of interrupt
    handling and context switches. Allows direct polling of a network
    device from socket operations, such as recvmsg() and poll().

    Currently ixgbe, mlx4, and bnx2x support this feature.

    Full high level description, performance numbers, and design in
    commit 0a4db187a999 ("Merge branch 'll_poll'")

    From Eliezer Tamir.

    2) With the routing cache removed, ip_check_mc_rcu() gets exercised
    more than ever before in the case where we have lots of multicast
    addresses. Use a hash table instead of a simple linked list, from
    Eric Dumazet.

    3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from
    Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski,
    Marek Puzyniak, Michal Kazior, and Sujith Manoharan.

    4) Support reporting the TUN device persist flag to userspace, from
    Pavel Emelyanov.

    5) Allow controlling network device VF link state using netlink, from
    Rony Efraim.

    6) Support GRE tunneling in openvswitch, from Pravin B Shelar.

    7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from
    Daniel Borkmann and Eric Dumazet.

    8) Allow controlling of TCP quickack behavior on a per-route basis,
    from Cong Wang.

    9) Several bug fixes and improvements to vxlan from Stephen
    Hemminger, Pravin B Shelar, and Mike Rapoport. In particular,
    support receiving on multiple UDP ports.

    10) Major cleanups, particular in the area of debugging and cookie
    lifetime handline, to the SCTP protocol code. From Daniel
    Borkmann.

    11) Allow packets to cross network namespaces when traversing tunnel
    devices. From Nicolas Dichtel.

    12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
    manner akin to how we monitor real network traffic via ptype_all.
    From Daniel Borkmann.

    13) Several bug fixes and improvements for the new alx device driver,
    from Johannes Berg.

    14) Fix scalability issues in the netem packet scheduler's time queue,
    by using an rbtree. From Eric Dumazet.

    15) Several bug fixes in TCP loss recovery handling, from Yuchung
    Cheng.

    16) Add support for GSO segmentation of MPLS packets, from Simon
    Horman.

    17) Make network notifiers have a real data type for the opaque
    pointer that's passed into them. Use this to properly handle
    network device flag changes in arp_netdev_event(). From Jiri
    Pirko and Timo Teräs.

    18) Convert several drivers over to module_pci_driver(), from Peter
    Huewe.

    19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a
    O(1) calculation instead. From Eric Dumazet.

    20) Support setting of explicit tunnel peer addresses in ipv6, just
    like ipv4. From Nicolas Dichtel.

    21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet.

    22) Prevent a single high rate flow from overruning an individual cpu
    during RX packet processing via selective flow shedding. From
    Willem de Bruijn.

    23) Don't use spinlocks in TCP md5 signing fast paths, from Eric
    Dumazet.

    24) Don't just drop GSO packets which are above the TBF scheduler's
    burst limit, chop them up so they are in-bounds instead. Also
    from Eric Dumazet.

    25) VLAN offloads are missed when configured on top of a bridge, fix
    from Vlad Yasevich.

    26) Support IPV6 in ping sockets. From Lorenzo Colitti.

    27) Receive flow steering targets should be updated at poll() time
    too, from David Majnemer.

    28) Fix several corner case regressions in PMTU/redirect handling due
    to the routing cache removal, from Timo Teräs.

    29) We have to be mindful of ipv4 mapped ipv6 sockets in
    upd_v6_push_pending_frames(). From Hannes Frederic Sowa.

    Hence, replace the use of SYMBOL_NAME() and SYMBOL_NAME_LABEL() in h8300
    assembler sources by hardcoding the underscore symbol prefix, like other
    architectures (blackfin/metag) do.

    This allows to kill SYMBOL_NAME_LABEL(). Now becomes empty,

  • Currently, when a socket receives something on the error queue it only wakes up
    the socket on select if it is in the "read" list, that is the socket has
    something to read. It is useful also to wake the socket if it is in the error
    list, which would enable software to wait on error queue packets without waking
    up for regular data on the socket. The main use case is for receiving
    timestamped transmit packets which return the timestamp to the socket via the
    error queue. This enables an application to select on the socket for the error
    queue only instead of for the regular traffic.

    -v2-
    * Added the SO_SELECT_ERR_QUEUE socket option to every architechture specific file
    * Modified every socket poll function that checks error queue

  • Pull vfs pile (part one) from Al Viro:
    "Assorted stuff - cleaning namei.c up a bit, fixing ->d_name/->d_parent
    locking violations, etc.

    The most visible changes here are death of FS_REVAL_DOT (replaced with
    "has ->d_weak_revalidate()") and a new helper getting from struct file
    to inode. Some bits of preparation to xattr method interface changes.

    Misc patches by various people sent this cycle *and* ocfs2 fixes from
    several cycles ago that should've been upstream right then.

    PS: the next vfs pile will be xattr stuff."

  • Pull signal handling cleanups from Al Viro:
    "This is the first pile; another one will come a bit later and will
    contain SYSCALL_DEFINE-related patches.

    - a bunch of signal-related syscalls (both native and compat)
    unified.

    - a bunch of compat syscalls switched to COMPAT_SYSCALL_DEFINE
    (fixing several potential problems with missing argument
    validation, while we are at it)

    - a lot of now-pointless wrappers killed

    - a couple of architectures (cris and hexagon) forgot to save
    altstack settings into sigframe, even though they used the
    (uninitialized) values in sigreturn; fixed.

    - microblaze fixes for delivery of multiple signals arriving at once

    - saner set of helpers for signal delivery introduced, several
    architectures switched to using those."

  • While a privileged program can open a raw socket, attach some
    restrictive filter and drop its privileges (or send the socket to an
    unprivileged program through some Unix socket), the filter can still
    be removed or modified by the unprivileged program. This commit adds a
    socket option to lock the filter (SO_LOCK_FILTER) preventing any
    modification of a socket filter program.

    This is similar to OpenBSD BIOCLOCK ioctl on bpf sockets, except even
    root is not allowed change/drop the filter.

    The state of the lock can be read with getsockopt(). No error is
    triggered if the state is not changed. -EPERM is returned when a user
    tries to remove the lock or to change/remove the filter while the lock
    is active. The check is done directly in sk_attach_filter() and
    sk_detach_filter() and does not affect only setsockopt() syscall.
