  • 954b2e7f4   [NET] AX.25 Kconfig and docs updates and fixes ... Browse Code »

    o The AX.25 Howto is unmaintained since several years. I've replaced it
    with a wiki at http://www.linux-ax25.org which provides more uptodate
    information.
    o Change default for AX25_DAMA_SLAVE to Y. AX25_DAMA_SLAVE only compiles
    in support for DAMA but doesn't activate it. I hope this gets Linux
    distributions to ship their AX.25 kernels with AX25_DAMA_SLAVE enabled.
    The price for this would be very small.
    o Delete historic changelog from comments, that's what SCM systems are
    meant to do.
    o ---help--- in Kconfig looks so yellingly eye insulting. Use just help.
    o Rewrite the commented out piece of old Linux 2.4 configuration language
    to Kconfig for consistency.
    o Fixup dependencies.

  • 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.

  • 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).

  • 9a32144e9   [PATCH] mark struct file_operations const 7 ... 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.

  • c7c694d19   [AX.25]: Fix potencial memory hole. ... Browse Code »

    If the AX.25 dialect chosen by the sysadmin is set to DAMA master / 3
    (or DAMA slave / 2, if CONFIG_AX25_DAMA_SLAVE=n) ax25_kick() will fall
    through the switch statement without calling ax25_send_iframe() or any
    other function that would eventually free skbn thus leaking the packet.

    Fix by restricting the sysctl inferface to allow only actually supported
    AX.25 dialects.

    The system administration mistake needed for this to happen is rather
    unlikely, so this is an uncritical hole.

    Coverity #651.

  • 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.
