  • b5e5fa5e0   [NET]: Add a dev_ioctl() fallback to sock_ioctl() ... Browse Code »

    Currently all network protocols need to call dev_ioctl as the default
    fallback in their ioctl implementations. This patch adds a fallback
    to dev_ioctl to sock_ioctl if the protocol returned -ENOIOCTLCMD.
    This way all the procotol ioctl handlers can be simplified and we don't
    need to export dev_ioctl.

  • 90ddc4f04   [NET]: move struct proto_ops to const ... Browse Code »

    I noticed that some of 'struct proto_ops' used in the kernel may share
    a cache line used by locks or other heavily modified data. (default
    linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at
    least)

    This patch makes sure a 'struct proto_ops' can be declared as const,
    so that all cpus can share all parts of it without false sharing.

    This is not mandatory : a driver can still use a read/write structure
    if it needs to (and eventually a __read_mostly)

    I made a global stubstitute to change all existing occurences to make
    them const.

    This should reduce the possibility of false sharing on SMP, and
    speedup some socket system calls.

  • c1cbe4b7a   [NET]: Avoid atomic xchg() for non-error case ... Browse Code »

    It also looks like there were 2 places where the test on sk_err was
    missing from the event wait logic (in sk_stream_wait_connect and
    sk_stream_wait_memory), while the rest of the sock_error() users look
    to be doing the right thing. This version of the patch fixes those,
    and cleans up a few places that were testing ->sk_err directly.

  • 381998241   [LLC]: Fix compiler warnings introduced by TX window scaling changes. ... Browse Code »

    Noticed by Olaf Hering.

    The comparisons want a u8 here (the data type on the left-hand branch
    is a u8 structure member, and the constant on the right-hand branch is
    "~((u8) 128)"), but C turns it into an integer so we get:

    net/llc/llc_c_ac.c: In function `llc_conn_ac_inc_npta_value':
    net/llc/llc_c_ac.c:998: warning: comparison is always true due to limited range of data type
    net/llc/llc_c_ac.c:999: warning: large integer implicitly truncated to unsigned type

    Fix this up by explicitly recasting the right-hand branch constant
    into a "u8" once more.

  • dd0fc66fb   [PATCH] gfp flags annotations - part 1 ... Browse Code »

    - added typedef unsigned int __nocast gfp_t;

    - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
    the same warnings as far as sparse is concerned, doesn't change
    generated code (from gcc point of view we replaced unsigned int with
    typedef) and documents what's going on far better.

  • c752f0739   [TCP]: Move the tcp sock states to net/tcp_states.h ... Browse Code »

    Lots of places just needs the states, not even linux/tcp.h, where this
    enum was, needs it.

    This speeds up development of the refactorings as less sources are
    rebuilt when things get moved from net/tcp.h.

  • f2ccd8fa0   [NET]: Kill skb->real_dev ... Browse Code »

    Bonding just wants the device before the skb_bond()
    decapsulation occurs, so simply pass that original
    device into packet_type->func() as an argument.

    It remains to be seen whether we can use this same
    exact thing to get rid of skb->input_dev as well.

  • 8728b834b   [NET]: Kill skb->list ... Browse Code »

    Remove the "list" member of struct sk_buff, as it is entirely
    redundant. All SKB list removal callers know which list the
    SKB is on, so storing this in sk_buff does nothing other than
    taking up some space.

    Two tricky bits were SCTP, which I took care of, and two ATM
    drivers which Francois Romieu fixed
    up.

  • b03efcfb2   [NET]: Transform skb_queue_len() binary tests into skb_queue_empty() ... Browse Code »

    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.

    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!
