:  Log:
:  Don't write the name of the sysctl to a temporary variable and truncate
:  it on the '=' there. If the argument is actually longer than the buffer,
:  this would result in a NULL reference. Instead, allocate the necessary
:  buffer with alloca and copy the name part.

    Use malloc instead of alloca please.  Also, alloca is non-portable
    and using it inside a braced substatement is even more non-portable.
