  • 7562f876c   [NET]: Rework dev_base via list_head (v3) ... Browse Code »

    Cleanup of dev_base list use, with the aim to simplify making device
    list per-namespace. In almost every occasion, use of dev_base variable
    and dev->next pointer could be easily replaced by for_each_netdev
    loop. A few most complicated places were converted to using
    first_netdev()/next_netdev().

  • 0b4d41471   [PATCH] sysctl: remove insert_at_head from register_sysctl ... Browse Code »

    The semantic effect of insert_at_head is that it would allow new registered
    sysctl entries to override existing sysctl entries of the same name. Which is
    pain for caching and the proc interface never implemented.

    I have done an audit and discovered that none of the current users of
    register_sysctl care as (excpet for directories) they do not register
    duplicate sysctl entries.

    So this patch simply removes the support for overriding existing entries in
    the sys_sysctl interface since no one uses it or cares and it makes future
    enhancments harder.

    The sysctl numbers used are unique so setting the insert_at_head flag serves
    no semantic purpose, so it is just confusing.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

  • da7071d7e   [PATCH] mark struct file_operations const 8 ... Browse Code »

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • 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.

  • e21ce8c7c   [NETROM]: Implement G8PZT Circuit reset for NET/ROM ... Browse Code »

    NET/ROM is lacking a connection reset like TCP's RST flag which at times
    may result in a connecting having to slowly timing out instead of just being
    reset. An earlier attempt to reset the connection by sending a
    NR_CONNACK | NR_CHOKE_FLAG transport was inacceptable as it did result in
    crashes of BPQ systems. An alternative approach of introducing a new
    transport type 7 (NR_RESET) has be implemented several years ago in
    Paula Jayne Dowie G8PZT's Xrouter.

    Implement NR_RESET for Linux's NET/ROM but like any messing with the state
    engine consider this experimental for now and thus control it by a sysctl
    (net.netrom.reset) which for the time being defaults to off.

    ARP over NET/ROM does not exist so it's obviously not implemented on any
    NET/ROM stack, so the NET/ROM interfaces really should default to IFF_NOARP.
