  • 6f5601251   net, TTY: initialize tty->driver_data before usage ... Browse Code »

    Commit 9c650ffc ("TTY: ircomm_tty, add tty install") split _open() to
    _install() and _open(). It also moved the initialization of driver_data
    out of open(), but never added it to install() - causing a NULL ptr
    deref whenever the driver was used.

  • 096895818   silence some noisy printks in irda ... Browse Code »

    Fuzzing causes these printks to spew constantly.
    Changing them to DEBUG statements is consistent with other usage in the file,
    and makes them disappear when CONFIG_IRDA_DEBUG is disabled.

    Pull networking changes from David Miller:

    1) GRE now works over ipv6, from Dmitry Kozlov.

    2) Make SCTP more network namespace aware, from Eric Biederman.

    3) TEAM driver now works with non-ethernet devices, from Jiri Pirko.

    4) Make openvswitch network namespace aware, from Pravin B Shelar.

    5) IPV6 NAT implementation, from Patrick McHardy.

    6) Server side support for TCP Fast Open, from Jerry Chu and others.

    7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel
    Borkmann.

    8) Increate the loopback default MTU to 64K, from Eric Dumazet.

    9) Use a per-task rather than per-socket page fragment allocator for
    outgoing networking traffic. This benefits processes that have very
    many mostly idle sockets, which is quite common.

    From Eric Dumazet.

    10) Use up to 32K for page fragment allocations, with fallbacks to
    smaller sizes when higher order page allocations fail. Benefits are
    a) less segments for driver to process b) less calls to page
    allocator c) less waste of space.

    From Eric Dumazet.

    11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.

    12) VXLAN device driver, one way to handle VLAN issues such as the
    limitation of 4096 VLAN IDs yet still have some level of isolation.
    From Stephen Hemminger.

    13) As usual there is a large boatload of driver changes, with the scale
    perhaps tilted towards the wireless side this time around.

    Fix up various fairly trivial conflicts, mostly caused by the user
    namespace changes.

  • 15e473046   netlink: Rename pid to portid to avoid confusion ... Browse Code »

    It is a frequent mistake to confuse the netlink port identifier with a
    process identifier. Try to reduce this confusion by renaming fields
    that hold port identifiers portid instead of pid.

    I have carefully avoided changing the structures exported to
    userspace to avoid changing the userspace API.

    I have successfully built an allyesconfig kernel with this change.

    In most of the time, the driver needs to check if the cts flow control

    which is not a grace way. So add a new wraper function to make the code

    Adding casts of objects to the same type is unnecessary
    and confusing for a human reader.

    For example, this cast:

    int y;
    int *p = (int *)&y;

    I used the coccinelle script below to find and remove these
    unnecessary casts. I manually removed the conversions this
    script produces of casts with __force and __user.

    This makes it clearer which sysctls are relative to your current network

    This makes it a little less error prone by not exposing sysctls for the
    initial network namespace in other namespaces.

    This is the same way we handle all of our other network interfaces to

    Checking if tty->index is in bounds is not needed. The tty has the
    index set in the initial open. This is done in get_tty_driver. And it
    can be only in interval num).

    So remove the tests which check exactly this interval. Some are
    left untouched as they check against the current backing device count.
    (Leaving apart that the check is racy in most of the cases.)

    pti driver sets something different to what it passes to
