  • d1db275dd   ipv6: ip6mr: support multiple tables ... Browse Code »

    This patch adds support for multiple independant multicast routing instances,
    named "tables".

    Userspace multicast routing daemons can bind to a specific table instance by
    issuing a setsockopt call using a new option MRT6_TABLE. The table number is
    stored in the raw socket data and affects all following ip6mr setsockopt(),
    getsockopt() and ioctl() calls. By default, a single table (RT6_TABLE_DFLT)
    is created with a default routing rule pointing to it. Newly created pim6reg
    devices have the table number appended ("pim6regX"), with the exception of
    devices created in the default table, which are named just "pim6reg" for
    compatibility reasons.

    Packets are directed to a specific table instance using routing rules,
    similar to how regular routing rules work. Currently iif, oif and mark
    are supported as keys, source and destination addresses could be supported
    additionally.

    Example usage:

    - bind pimd/xorp/... to a specific table:

    uint32_t table = 123;
    setsockopt(fd, SOL_IPV6, MRT6_TABLE, &table, sizeof(table));

    - create routing rules directing packets to the new table:

    # ip -6 mrule add iif eth0 lookup 123
    # ip -6 mrule add oif eth0 lookup 123

    Now that cache entries in unres_queue don't need to be distinguished by their
    network namespace pointer anymore, we can remove it from struct mfc6_cache
    add pass the namespace as function argument to the functions that need it.

  • b7058842c   net: Make setsockopt() optlen be unsigned. ... Browse Code »

    This provides safety against negative optlen at the type
    level instead of depending upon (sometimes non-trivial)
    checks against this sprinkled all over the the place, in
    each and every implementation.

    Based upon work done by Arjan van de Ven and feedback
    from Linus Torvalds.

  • 85efde6f4   make exported headers use strict posix types ... Browse Code »

    A number of standard posix types are used in exported headers, which
    is not allowed if __STRICT_KERNEL_NAMES is defined. In order to
    get rid of the non-__STRICT_KERNEL_NAMES part and to make sane headers
    the default, we have to change them all to safe types.

    There are also still some leftovers in reiserfs_fs.h, elfcore.h
    and coda.h, but these files have not compiled in user space for
    a long time.

    This leaves out the various integer types ({u_,u,}int{8,16,32,64}_t),
    which we take care of separately.

  • 8229efdae   netns: ip6mr: enable namespace support in ipv6 multicast forwarding code ... Browse Code »

    This last patch makes the appropriate changes to use and propagate the
    network namespace where needed in IPv6 multicast forwarding code.

    This consists mainly in replacing all the remaining init_net occurences
    with current netns pointer retrieved from sockets, net devices or
    mfc6_caches depending on the routines' contexts.

    Some routines receive a new 'struct net' parameter to propagate the current
    netns:
    * ip6mr_get_route
    * ip6mr_cache_report
    * ip6mr_cache_find
    * ip6mr_cache_unresolved
    * mif6_add/mif6_delete
    * ip6mr_mfc_add/ip6mr_mfc_delete
    * ip6mr_reg_vif

    All the IPv6 multicast forwarding variables moved to struct netns_ipv6 by
    the previous patches are now referenced in the correct namespace.

    Changelog:
    ==========
    * Take into account the net associated to mfc6_cache when matching entries in
    mfc_unres_queue list.
    * Call mroute_clean_tables() in ip6mr_net_exit() to free memory allocated
    per-namespace.
    * Call dev_net_set() in ip6mr_reg_vif() to initialize dev->nd_net
    correctly.

  • 58701ad41   netns: ip6mr: store netns in struct mfc6_cache ... Browse Code »

    This patch stores into struct mfc6_cache the network namespace each
    mfc6_cache belongs to. The new member is mfc6_net.

    mfc6_net is assigned at cache allocation and doesn't change during
    the rest of the cache entry life.

    This will help to retrieve the current netns around the IPv6 multicast
    forwarding code.

    At the moment, all mfc6_cache are allocated in init_net.

    Changelog:
    ==========
    * Use write_pnet()/read_pnet() to set and get mfc6_net.

  • 7c19a3d28   net: Unbreak userspace usage of linux/mroute.h ... Browse Code »

    Nothing in linux/pim.h should be exported to userspace.

    This should fix the XORP build failure reported by
    Jose Calhariz, the debain package maintainer.

    Nothing originally in linux/mroute.h was exported to userspace
    ever, but some of this stuff started to be when it was moved into
    this new linux/pim.h, and that was wrong. If we didn't provide these
    definitions for 10 years we can reasonably expect that applications
    defined this stuff locally or used GLIBC headers providing the
    protocol definitions. And as such the only result of this can
    be conflict and userland build breakage.
