    net/sched: add ACT_CSUM action to update packets checksums

    ACT_CSUM can be called just after ACT_PEDIT in order to re-compute some
    altered checksums in IPv4 and IPv6 packets. The following checksums are
    supported by this patch:
    - IPv4: IPv4 header, ICMP, IGMP, TCP, UDP & UDPLite
    - IPv6: ICMPv6, TCP, UDP & UDPLite
    It's possible to request in the same action to update different kind of
    checksums, if the packets flow mix TCP, UDP and UDPLite, ...

    An example of usage is done in the associated iproute2 patch.

    Version 3 changes:
    - remove useless goto instructions
    - improve IPv6 hop options decoding

    Version 2 changes:
    - coding style correction
    - remove useless arguments of some functions
    - use stack in tcf_csum_dump()
    - add tcf_csum_skb_nextlayer() to factor code

    This cleanup patch puts struct/union/enum opening braces,
    in first line to ease grep games.

    struct something
    {

    becomes :

    struct something {

  • b42199523   [PKT_SCHED]: Add stateless NAT ... Browse Code »

    Stateless NAT is useful in controlled environments where restrictions are
    placed on through traffic such that we don't need connection tracking to
    correctly NAT protocol-specific data.

    In particular, this is of interest when the number of flows or the number
    of addresses being NATed is large, or if connection tracking information
    has to be replicated and where it is not practical to do so.

    Previously we had stateless NAT functionality which was integrated into
    the IPv4 routing subsystem. This was a great solution as long as the NAT
    worked on a subnet to subnet basis such that the number of NAT rules was
    relatively small. The reason is that for SNAT the routing based system
    had to perform a linear scan through the rules.

    If the number of rules is large then major renovations would have take
    place in the routing subsystem to make this practical.

    For the time being, the least intrusive way of achieving this is to use
    the u32 classifier written by Alexey Kuznetsov along with the actions
    infrastructure implemented by Jamal Hadi Salim.

    The following patch is an attempt at this problem by creating a new nat
    action that can be invoked from u32 hash tables which would allow large
    number of stateless NAT rules that can be used/updated in constant time.

    The actual NAT code is mostly based on the previous stateless NAT code
    written by Alexey. In future we might be able to utilise the protocol
    NAT code from netfilter to improve support for other protocols.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
