  • 32927393d   sysctl: pass kernel pointers to ->proc_handler ... Browse Code »

    Instead of having all the sysctl handlers deal with user pointers, which
    is rather hairy in terms of the BPF interaction, copy the input to and
    from userspace in common code. This also means that the strings are
    always NUL-terminated by the common code, making the API a little bit
    safer.

    As most handler just pass through the data to one of the common handlers
    a lot of the changes are mechnical.

  • fe2c6338f   net: Convert uses of typedef ctl_table to struct ctl_table ... Browse Code »

    Reduce the uses of this unnecessary typedef.

    Done via perl script:

    $ git grep --name-only -w ctl_table net | \
    xargs perl -p -i -e '\
    sub trim { my ($local) = @_; $local =~ s/(^\s+|\s+$)//g; return $local; } \
    s/\b(?<!struct\s)ctl_table\b(\s*\*\s*|\s+\w+)/"struct ctl_table " . trim($1)/ge'

    Reflow the modified lines that now exceed 80 columns.

  • ec8f23ce0   net: Convert all sysctl registrations to register_net_sysctl ... Browse Code »

    This results in code with less boiler plate that is a bit easier
    to read.

    Additionally stops us from using compatibility code in the sysctl
    core, hastening the day when the compatibility code can be removed.

  • 5dd3df105   net: Move all of the network sysctls without a namespace into init_net. ... Browse Code »

    This makes it clearer which sysctls are relative to your current network
    namespace.

    This makes it a little less error prone by not exposing sysctls for the
    initial network namespace in other namespaces.

    This is the same way we handle all of our other network interfaces to
    userspace and I can't honestly remember why we didn't do this for
    sysctls right from the start.

  • f8572d8f2   sysctl net: Remove unused binary sysctl code ... Browse Code »

    Now that sys_sysctl is a compatiblity wrapper around /proc/sys
    all sysctl strategy routines, and all ctl_name and strategy
    entries in the sysctl tables are unused, and can be
    revmoed.

    In addition neigh_sysctl_register has been modified to no longer
    take a strategy argument and it's callers have been modified not
    to pass one.

  • 8d65af789   sysctl: remove "struct file *" argument of ->proc_handler ... Browse Code »

    It's unused.

    It isn't needed -- read or write flag is already passed and sysctl
    shouldn't care about the rest.

    It _was_ used in two places at arch/frv for some reason.

  • 6d9f239a1   net: '&' redux ... Browse Code »

    I want to compile out proc_* and sysctl_* handlers totally and
    stub them to NULL depending on config options, however usage of &
    will prevent this, since taking adress of NULL pointer will break
    compilation.

    So, drop & in front of every ->proc_handler and every ->strategy
    handler, it was never needed in fact.

  • 87ab4e20b   Phonet: proc interface for port range ... Browse Code »

    Phonet endpoints are bound to individual ports.
    This provides a /proc/sys/net/phonet (or sysctl) interface for
    selecting the range of automatically allocated ports (much like the
    ip_local_port_range with IPv4).
