  • This changeset basically moves tcp_sk()->{ca_ops,ca_state,etc} to inet_csk(),
    minimal renaming/moving done in this changeset to ease review.

    Most of it is just changes of struct tcp_sock * to struct sock * parameters.

    With this we move to a state closer to two interesting goals:

    1. Generalisation of net/ipv4/tcp_diag.c, becoming inet_diag.c, being used
    for any INET transport protocol that has struct inet_hashinfo and are
    derived from struct inet_connection_sock. Keeps the userspace API, that will
    just not display DCCP sockets, while newer versions of tools can support
    DCCP.

    2. INET generic transport pluggable Congestion Avoidance infrastructure, using
    the current TCP CA infrastructure with DCCP.

  • This also improves reqsk_queue_prune and renames it to
    inet_csk_reqsk_queue_prune, as it deals with both inet_connection_sock
    and inet_request_sock objects, not just with request_sock ones thus
    belonging to inet_request_sock.

  • With this we're very close to getting all of the current TCP
    refactorings in my dccp-2.6 tree merged, next changeset will export
    some functions needed by the current DCCP code and then dccp-2.6.git
    will be born!

  • Completing the previous changeset, this also generalises tcp_v4_synq_add,
    renaming it to inet_csk_reqsk_queue_hash_add, already geing used in the
    DCCP tree, which I plan to merge RSN.

  • This creates struct inet_connection_sock, moving members out of struct
    tcp_sock that are shareable with other INET connection oriented
    protocols, such as DCCP, that in my private tree already uses most of
    these members.

    The functions that operate on these members were renamed, using a
    inet_csk_ prefix while not being moved yet to a new file, so as to
    ease the review of these changes.

  • This is part of the grand scheme to eliminate the qlen
    member of skb_queue_head, and subsequently remove the
    'list' member of sk_buff.

    Most users of skb_queue_len() want to know if the queue is
    empty or not, and that's trivially done with skb_queue_empty()
    which doesn't use the skb_queue_head->qlen member and instead
    uses the queue list emptyness as the test.

  • This chunks out the accept_queue and tcp_listen_opt code and moves
    them to net/core/request_sock.c and include/net/request_sock.h, to
    make it useful for other transport protocols, DCCP being the first one
    to use it.

    Next patches will rename tcp_listen_opt to accept_sock and remove the
    inline tcp functions that just call a reqsk_queue_ function.

  • Ok, this one just renames some stuff to have a better namespace and to
    dissassociate it from TCP:

    struct open_request -> struct request_sock
    tcp_openreq_alloc -> reqsk_alloc
    tcp_openreq_free -> reqsk_free
    tcp_openreq_fastfree -> __reqsk_free

    With this most of the infrastructure closely resembles a struct
    sock methods subset.

  • Kept this first changeset minimal, without changing existing names to
    ease peer review.

    Basicaly tcp_openreq_alloc now receives the or_calltable, that in turn
    has two new members:

    ->slab, that replaces tcp_openreq_cachep
    ->obj_size, to inform the size of the openreq descendant for
    a specific protocol

    The protocol specific fields in struct open_request were moved to a
    class hierarchy, with the things that are common to all connection
    oriented PF_INET protocols in struct inet_request_sock, the TCP ones
    in tcp_request_sock, that is an inet_request_sock, that is an
    open_request.

    I.e. this uses the same approach used for the struct sock class
    hierarchy, with sk_prot indicating if the protocol wants to use the
    open_request infrastructure by filling in sk_prot->rsk_prot with an
    or_calltable.

    Results? Performance is improved and TCP v4 now uses only 64 bytes per
    open request minisock, down from 96 without this patch :-)

    Next changeset will rename some of the structs, fields and functions
    mentioned above, struct or_calltable is way unclear, better name it
    struct request_sock_ops, s/struct open_request/struct request_sock/g,
    etc.

  • 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!
