    Clean up some unused macros in net/*.
    1. be left for code change. e.g. PGV_FROM_VMALLOC, PGV_FROM_VMALLOC, KMEM_SAFETYZONE.
    2. never be used since introduced to kernel.
    e.g. P9_RDMA_MAX_SGE, UTIL_CTRL_PKT_SIZE.

  • 15fd0cd9a   net: autoconvert trivial BKL users to private mutex ... Browse Code »

    All these files use the big kernel lock in a trivial
    way to serialize their private file operations,
    typically resulting from an earlier semi-automatic
    pushdown from VFS.

    None of these drivers appears to want to lock against
    other code, and they all use the BKL as the top-level
    lock in their file operations, meaning that there
    is no lock-order inversion problem.

    Consequently, we can remove the BKL completely,
    replacing it with a per-file mutex in every case.
    Using a scripted approach means we can avoid
    typos.

    file=$1
    name=$2
    if grep -q lock_kernel ${file} ; then
    if grep -q 'include.*linux.mutex.h' ${file} ; then
    sed -i '/include.*/d' ${file}
    else
    sed -i 's/include.*.*$/include /g' ${file}
    fi
    sed -i ${file} \
    -e "/^#include.*linux.mutex.h/,$ {
    1,/^\(static\|int\|long\)/ {
    /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex);

    } }" \
    -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \
    -e '/[ ]*cycle_kernel_lock();/d'
    else
    sed -i -e '/include.*\/d' ${file} \
    -e '/cycle_kernel_lock()/d'
    fi

  • 405f55712   headers: smp_lock.h redux ... Browse Code »

    * Remove smp_lock.h from files which don't need it (including some headers!)
    * Add smp_lock.h to files which do need it
    * Make smp_lock.h include conditional in hardirq.h
    It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

    This will make hardirq.h inclusion cheaper for every PREEMPT=n config
    (which includes allmodconfig/allyesconfig, BTW)

  • 457c4cbc5   [NET]: Make /proc/net per network namespace ... Browse Code »

    This patch makes /proc/net per network namespace. It modifies the global
    variables proc_net and proc_net_stat to be per network namespace.
    The proc_net file helpers are modified to take a network namespace argument,
    and all of their callers are fixed to pass &init_net for that argument.
    This ensures that all of the /proc/net files are only visible and
    usable in the initial network namespace until the code behind them
    has been updated to be handle multiple network namespaces.

    Making /proc/net per namespace is necessary as at least some files
    in /proc/net depend upon the set of network devices which is per
    network namespace, and even more files in /proc/net have contents
    that are relevant to a single network namespace.

  • 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.

  • 8db60bcf3   [WAN]: Remove broken and unmaintained Sangoma drivers. ... Browse Code »

    The in-kernel Sangoma drivers are both not compiling and marked as BROKEN
    since at least kernel 2.6.0.

    Sangoma offers out-of-tree drivers, and David Mandelstam told me Sangoma
    does no longer maintain the in-kernel drivers and prefers to provide them
    as a separate installation package.

    This patch therefore removes these drivers.

  • 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.

  • 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.

  • e49332bd1   [PATCH] misc verify_area cleanups ... Browse Code »

    There were still a few comments left refering to verify_area, and two
    functions, verify_area_skas & verify_area_tt that just wrap corresponding
    access_ok_skas & access_ok_tt functions, just like verify_area does for
    access_ok - deprecate those.

    There was also a few places that still used verify_area in commented-out
    code, fix those up to use access_ok.

    After applying this one there should not be anything left but finally
    removing verify_area completely, which will happen after a kernel release
    or two.

    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!
