  • 6f9120422   [PATCH] for_each_possible_cpu: network codes ... Browse Code »

    for_each_cpu() actually iterates across all possible CPUs. We've had mistakes
    in the past where people were using for_each_cpu() where they should have been
    iterating across only online or present CPUs. This is inefficient and
    possibly buggy.

    We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the
    future.

    This patch replaces for_each_cpu with for_each_possible_cpu under /net

  • 46b86a2da   [NET]: Use NIP6_FMT in kernel.h ... Browse Code »

    There are errors and inconsistency in the display of NIP6 strings.
    ie: net/ipv6/ip6_flowlabel.c

    There are errors and inconsistency in the display of NIPQUAD strings too.
    ie: net/netfilter/nf_conntrack_ftp.c

    This patch:
    adds NIP6_FMT to kernel.h
    changes all code to use NIP6_FMT
    fixes net/ipv6/ip6_flowlabel.c
    adds NIPQUAD_FMT to kernel.h
    fixes net/netfilter/nf_conntrack_ftp.c
    changes a few uses of "%u.%u.%u.%u" to NIPQUAD_FMT for symmetry to NIP6_FMT

  • 951dbc8ac   [IPV6]: Move nextheader offset to the IP6CB ... Browse Code »

    Move nextheader offset to the IP6CB to make it possible to pass a
    packet to ip6_input_finish multiple times and have it skip already
    parsed headers. As a nice side effect this gets rid of the manual
    hopopts skipping in ip6_input_finish.

  • 9b5b5cff9   [NET]: Add const markers to various variables. ... Browse Code »

    the patch below marks various variables const in net/; the goal is to
    move them to the .rodata section so that they can't false-share
    cachelines with things that get written to, as well as potentially
    helping gcc a bit with optimisations. (these were found using a gcc
    patch to warn about such variables)

  • fb286bb29   [NET]: Detect hardware rx checksum faults correctly ... Browse Code »

    Here is the patch that introduces the generic skb_checksum_complete
    which also checks for hardware RX checksum faults. If that happens,
    it'll call netdev_rx_csum_fault which currently prints out a stack
    trace with the device name. In future it can turn off RX checksum.

    I've converted every spot under net/ that does RX checksum checks to
    use skb_checksum_complete or __skb_checksum_complete with the
    exceptions of:

    * Those places where checksums are done bit by bit. These will call
    netdev_rx_csum_fault directly.

    * The following have not been completely checked/converted:

    ipmr
    ip_vs
    netfilter
    dccp

    This patch is based on patches and suggestions from Stephen Hemminger
    and David S. Miller.

  • 670c02c2b   [NET]: Wider use of for_each_*cpu() ... Browse Code »

    In 'net' change the explicit use of for-loops and NR_CPUS into the
    general for_each_cpu() or for_each_online_cpu() constructs, as
    appropriate. This widens the scope of potential future optimizations
    of the general constructs, as well as takes advantage of the existing
    optimizations of first_cpu() and next_cpu(), which is advantageous
    when the true CPU count is much smaller than NR_CPUS.

  • 2dac4b96b   [IPV6]: Repair Incoming Interface Handling for Raw Socket. ... Browse Code »

    Due to changes to enforce checking interface bindings,
    sockets did not see loopback packets bound for our local address
    on our interface.

    e.g.)
    When we ping6 fe80::1%eth0, skb->dev points loopback_dev while
    IP6CB(skb)->iif indicates eth0.

    This patch fixes the issue by using appropriate incoming interface,
    in the sense of scoping architecture.

  • 84427d533   [IPV6]: Ensure to use icmpv6_socket in non-preemptive context. ... Browse Code »

    We saw following trace several times:

    |BUG: using smp_processor_id() in preemptible [00000001] code: httpd/30137
    |caller is icmpv6_send+0x23/0x540
    | [] smp_processor_id+0x9b/0xb8
    | [] icmpv6_send+0x23/0x540

    This is because of icmpv6_socket, which is the only one user of
    smp_processor_id() in icmpv6_send(), AFAIK.

    Since it should be used in non-preemptive context,
    let's defer the dereference after disabling preemption
    (by icmpv6_xmit_lock()).

  • 0d3d077cd   [SELINUX]: Fix ipv6_skip_exthdr() invocation causing OOPS. ... Browse Code »

    The SELinux hooks invoke ipv6_skip_exthdr() with an incorrect
    length final argument. However, the length argument turns out
    to be superfluous.

    I was just reading ipv6_skip_exthdr and it occured to me that we can
    get rid of len altogether. The only place where len is used is to
    check whether the skb has two bytes for ipv6_opt_hdr. This check
    is done by skb_header_pointer/skb_copy_bits anyway.

    Now it might appear that we've made the code slower by deferring
    the check to skb_copy_bits. However, this check should not trigger
    in the common case so this is OK.

    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!
