  • f6c90b71a   [NET]: Fix ipx/econet/appletalk/irda ioctl crashes ... Browse Code »

    Fix kernel oopses whenever somebody issues compatible ioctl on AppleTalk,
    Econet, IPX or IRDA socket. For AppleTalk/Econet/IRDA it restores state
    in which these sockets were before compat_ioctl was introduced to the socket
    ops, for IPX it implements support for 4 ioctls which were not implemented
    before - as these ioctls use structures which match between 32bit and 64bit
    userspace, no special code is needed, just call 64bit ioctl handler.

  • 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.

  • 14c850212   [INET_SOCK]: Move struct inet_sock & helper functions to net/inet_sock.h ... Browse Code »

    To help in reducing the number of include dependencies, several files were
    touched as they were getting needed headers indirectly for stuff they use.

    Thanks also to Alan Menegotto for pointing out that net/dccp/proto.c had
    linux/dccp.h include twice.

  • 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.

  • e5ed63991   [IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnl ... Browse Code »

    The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
    introduces __in_dev_get_rcu() to cover the second case.

    1) RCU with refcnt should use in_dev_get().
    2) RCU without refcnt should use __in_dev_get_rcu().
    3) All others must hold RTNL and use __in_dev_get_rtnl().

    There is one exception in net/ipv4/route.c which is in fact a pre-existing
    race condition. I've marked it as such so that we remember to fix it.

    This patch is based on suggestions and prior work by Suzanne Wood and
    Paul McKenney.

  • 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.

  • 6a2e9b738   [NET]: move config options out to individual protocols ... Browse Code »

    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.

    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!
