  • c996d8b9a   Docs/Kconfig: Update: osdl.org -> linuxfoundation.org ... Browse Code »

    Some of the documentation refers to web pages under
    the domain `osdl.org'. However, `osdl.org' now
    redirects to `linuxfoundation.org'.

    Rather than rely on redirections, this patch updates
    the addresses appropriately; for the most part, only
    documentation that is meant to be current has been
    updated.

    The patch should be pretty quick to scan and check;
    each new web-page url was gotten by trying out the
    original URL in a browser and then simply copying the
    the redirected URL (formatting as necessary).

    There is some conflict as to which one of these domain
    names is preferred:

    linuxfoundation.org
    linux-foundation.org

    So, I wrote:

    info@linuxfoundation.org

    and got this reply:

    Message-ID:
    Date: Mon, 15 Nov 2010 10:41:42 -0800
    From: David Ames

    ...

    linuxfoundation.org is preferred. The canonical name for our web site is
    www.linuxfoundation.org. Our list site is actually
    lists.linux-foundation.org.

    Regarding email linuxfoundation.org is preferred there are a few people
    who choose to use linux-foundation.org for their own reasons.

    Consequently, I used `linuxfoundation.org' for web pages and
    `lists.linux-foundation.org' for mailing-list web pages and email addresses;
    the only personal email address I updated from `@osdl.org' was that of
    Andrew Morton, who prefers `linux-foundation.org' according `git log'.

    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

    Allows the net_cls cgroup subsystem to be compiled as a module

    This patch modifies net/sched/cls_cgroup.c to allow the net_cls subsystem
    to be optionally compiled as a module instead of builtin. The
    cgroup_subsys struct is moved around a bit to allow the subsys_id to be
    either declared as a compile-time constant by the cgroup_subsys.h include
    in cgroup.h, or, if it's a module, initialized within the struct by
    cgroup_load_subsys.

  • 13d2a1d2b   pkt_sched: add DRR scheduler ... Browse Code »

    Add classful DRR scheduler as a more flexible replacement for SFQ.

    The main difference to the algorithm described in "Efficient Fair Queueing
    using Deficit Round Robin" is that this implementation doesn't drop packets
    from the longest queue on overrun because its classful and limits are
    handled by each individual child qdisc.

  • f40092373   pkt_sched: Control group classifier ... Browse Code »

    The classifier should cover the most common use case and will work
    without any special configuration.

    The principle of the classifier is to directly access the
    task_struct via get_current(). In order for this to work,
    classification requests from softirqs must be ignored. This is
    not a problem because the vast majority of packets in softirq
    context are not assigned to a task anyway. For this to work, a
    mechanism is needed to trace softirq context.

    This repost goes back to the method of relying on the number of
    nested bh disable calls for the sake of not adding too much
    complexity and the option to come up with something more reliable
    if actually needed.

  • 92651940a   pkt_sched: Add multiqueue scheduler support ... Browse Code »

    This patch is intended to add a qdisc to support the new tx multiqueue
    architecture by providing a band for each hardware queue. By doing
    this it is possible to support a different qdisc per physical hardware
    queue.

    This qdisc uses the skb->queue_mapping to select which band to place
    the traffic onto. It then uses a round robin w/ a check to see if the
    subqueue is stopped to determine which band to dequeue the packet from.

  • e5dfb8151   [NET_SCHED]: Add flow classifier ... Browse Code »

    Add new "flow" classifier, which is meant to extend the SFQ hashing
    capabilities without hard-coding new hash functions and also allows
    deterministic mappings of keys to classes, replacing some out of tree
    iptables patches like IPCLASSIFY (maps IPs to classes), IPMARK (maps
    IPs to marks, with fw filters to classes), ...

    Some examples:

    - Classic SFQ hash:

    tc filter add ... flow hash \
    keys src,dst,proto,proto-src,proto-dst divisor 1024

    - Classic SFQ hash, but using information from conntrack to work properly in
    combination with NAT:

    tc filter add ... flow hash \
    keys nfct-src,nfct-dst,proto,nfct-proto-src,nfct-proto-dst divisor 1024

    - Map destination IPs of 192.168.0.0/24 to classids 1-257:

    tc filter add ... flow map \
    key dst addend -192.168.0.0 divisor 256

    - alternatively:

    tc filter add ... flow map \
    key dst and 0xff

    - similar, but reverse ordered:

    tc filter add ... flow map \
    key dst and 0xff xor 0xff

    Perturbation is currently not supported because we can't reliable kill the
    timer on destruction.

    Since the old policer code is gone, TC actions are needed for policing.
    The ingress qdisc can get packets directly from netif_receive_skb()
    in case TC actions are enabled or through netfilter otherwise, but
    since without TC actions there is no policer the only thing it actually
    does is count packets.

    Remove the netfilter support and always require TC actions.

  • 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.

    No, they were there before too, but you have to go up one level to see

    It's better in 2.6.15-rc1-git5, but the menu structure is still a little

    Move the protocol specific config options out to the specific protocols.
    With this change net/Kconfig now starts to become readable and serve as a
    good basis for further re-structuring.

    The menu structure is left almost intact, except that indention is
    fixed in most cases. Most visible are the INET changes where several
    "depends on INET" are replaced with a single ifdef INET / endif pair.

    Several new files were created to accomplish this change - they are
    small but serve the purpose that config options are now distributed
    out where they belongs.
