    Pull security subsystem updates for 3.4 from James Morris:
    "The main addition here is the new Yama security module from Kees Cook,
    which was discussed at the Linux Security Summit last year. Its
    purpose is to collect miscellaneous DAC security enhancements in one
    place. This also marks a departure in policy for LSM modules, which
    were previously limited to being standalone access control systems.
    Chromium OS is using Yama, and I believe there are plans for Ubuntu,
    at least.

    This patchset also includes maintenance updates for AppArmor, TOMOYO
    and others."

    Since all that include/linux/if_ppp.h does is #include ,
    this replaces the occurrences of #include with
    #include .

    It also corrects an error in Documentation/networking/l2tp.txt, where
    it referenced include/linux/if_ppp.h as the source of some definitions
    that are actually now defined in include/linux/if_pppol2tp.h.

  • bf7daebb9   ppp: Move ioctl definitions from if_ppp.h to new ppp-ioctl.h ... Browse Code »

    This moves the definitions of the ioctls, constants and structures
    relating to the ppp_generic interface to userspace out from if_ppp.h
    to a new file, ppp-ioctl.h. The new file has my copyright since I
    designed and implemented the ppp_generic interface in the late 1990s.
    None of the contents of this file comes from the original if_ppp.h
    published by Carnegie Mellon University.

    Of the remainder of if_ppp.h, only the PPP_MTU definition was being
    used, and this replaces the uses of it with PPP_MRU (which is identical).
    Therefore, this replaces the entire file with the single line

    #include

    which clearly doesn't contain any CMU code. Thus I have removed the
    CMU copyright notice with its problematic advertising clause, and in
    fact since it's only one trivial line I have not added any other
    copyright notice.

  • 700920eb5   KEYS: Allow special keyrings to be cleared ... Browse Code »

    The kernel contains some special internal keyrings, for instance the DNS
    resolver keyring :

    2a93faf1 I----- 1 perm 1f030000 0 0 keyring .dns_resolver: empty

    It would occasionally be useful to allow the contents of such keyrings to be
    flushed by root (cache invalidation).

    Allow a flag to be set on a keyring to mark that someone possessing the
    sysadmin capability can clear the keyring, even without normal write access to
    the keyring.

    Set this flag on the special keyrings created by the DNS resolver, the NFS
    identity mapper and the CIFS identity mapper.

  • ccb1352e7   net: Add Open vSwitch kernel components. ... Browse Code »

    Open vSwitch is a multilayer Ethernet switch targeted at virtualized
    environments. In addition to supporting a variety of features
    expected in a traditional hardware switch, it enables fine-grained
    programmatic extension and flow-based control of the network.
    This control is useful in a wide variety of applications but is
    particularly important in multi-server virtualization deployments,
    which are often characterized by highly dynamic endpoints and the need
    to maintain logical abstractions for multiple tenants.

    The Open vSwitch datapath provides an in-kernel fast path for packet
    forwarding. It is complemented by a userspace daemon, ovs-vswitchd,
    which is able to accept configuration from a variety of sources and
    translate it into packet processing rules.

    See http://openvswitch.org for more information and userspace
    utilities.

    Rick Jones reported that TCP_CONGESTION sockopt performed on a listener
    was ignored for its children sockets : right after accept() the

    This seems an oversight of the initial design (quoted from Stephen)

    Based on prior investigation and patch from Rick.

    [PATCH V5 net-next] neigh: new unresolved queue limits

    unres_qlen is the number of frames we are able to queue per unresolved
    neighbour. Its default value (3) was never changed and is responsible
    for strange drops, especially if IP fragments are used, or multiple
    sessions start in parallel. Even a single tcp flow can hit this limit.

    $ arp -d 192.168.20.108 ; ping -c 2 -s 8000 192.168.20.108
    PING 192.168.20.108 (192.168.20.108) 8000(8028) bytes of data.

  • 3d249d4ca   net: introduce ethernet teaming device ... Browse Code »

    This patch introduces new network device called team. It supposes to be
    very fast, simple, userspace-driven alternative to existing bonding
    driver.

    Userspace library called libteam with couple of demo apps is available
    here:
    https://github.com/jpirko/libteam
    Note it's still in its dipers atm.

    teamlibteam use generic netlink for communication. That and rtnl
    suppose to be the only way to configure team device, no sysfs etc.

    Python binding of libteam was recently introduced.
    Daemon providing arpmon/miimon active-backup functionality will be
    introduced shortly. All what's necessary is already implemented in
    kernel team driver.

    v7->v8:
    - check ndo_ndo_vlan_rx_[add/kill]_vid functions before calling
    them.
    - use dev_kfree_skb_any() instead of dev_kfree_skb()

    v6->v7:
    - transmit and receive functions are not checked in hot paths.
    That also resolves memory leak on transmit when no port is
    present

    v5->v6:
    - changed couple of _rcu calls to non _rcu ones in non-readers

    v4->v5:
    - team_change_mtu() uses team->lock while travesing though port
    list
    - mac address changes are moved completely to jurisdiction of
    userspace daemon. This way the daemon can do FOM1, FOM2 and
    possibly other weird things with mac addresses.
    Only round-robin mode sets up all ports to bond's address then
    enslaved.
    - Extended Kconfig text

    v3->v4:
    - remove redundant synchronize_rcu from __team_change_mode()
    - revert "set and clear of mode_ops happens per pointer, not per
    byte"
    - extend comment of function __team_change_mode()

    v2->v3:
    - team_change_mtu() uses rcu version of list traversal to unwind
    - set and clear of mode_ops happens per pointer, not per byte
    - port hashlist changed to be embedded into team structure
    - error branch in team_port_enter() does cleanup now
    - fixed rtln->rtnl

    v1->v2:
    - modes are made as modules. Makes team more modular and
    extendable.
    - several commenters' nitpicks found on v1 were fixed
    - several other bugs were fixed.
    - note I ignored Eric's comment about roundrobin port selector
    as Eric's way may be easily implemented as another mode (mode
    "random") in future.
