40ea66cd9d Patch from Lars Kellogg-Stedman:
Glibc 2.1.3 (used by the Hardhat Linux SDK distributed by Cyclades)
    does not define IF_NAMESIZE in net/if.h.

7207b88d06 Patch from Lars Kellogg-Stedman:
This patch fixes endian problems with get_netmask().  I don't know if
    this is the cleanest solution, but it makes 'ipcalc -n' work on both
    an i386 system and a ppc system.

8a93179c14 Patch from Lars Kellogg-Stedman:
Erik, et al.

    The attached patch makes the following changes to networking/ifupdown.c:

    (1) It swaps all calls to 'ip link set' and 'ip addr set'.  This solves
    two problems:

      (a) Calling 'ip link set <dev> up' before assigning an address
      generates an error message, and

      (b) Under User Mode Linux, running in with ethernet interfaces
      in daemon mode, the MAC address for an interface is selected
      based on the IP address assigned to that interface.  If the
      interface is brought up before being assigned an IP address,
      it gets a null MAC.

    (2) It further cleans up run_mapping().

    This patch is against ifupdown.c revision 1.25.

0f08e53535 Patch from Lars Kellogg-Stedman:
I'm building BusyBox using a development kit for MontaVista Hardhat Linux
(PPC) -- which, at least in this instance, is based around kernel 2.2.14.
I've had to massage a few files in networking/libiproute/ to make it
compile.  Specifically:

  (1) Added a #include <sys/uio.h> for the iovec structure in
      libnetlink.c,

  (2) Put ifdefs in ll_types.c and ll_proto.c around various
      constants (ETH_P_xxx and ARPHRD_xxx) that weren't defined,

  (3) Make do_changename() in iplink.c require a kernel >=
      2.4.0 -- the ifr structure in my environment doesn't
      have the ifr_name attribute.  I've assumed this is
      a kernel dependency -- let me know if I ought to be
      checking something else.

      In the absence of the correct kernel, do_changename()
      always returns 0.

Attached is a patch against the current CVS that will make these changes.

4fe3ff8cff Patch from Glenn Engel
- more comments
- larger allowed number of CGI script variables
- ifdefs for regression test hooks
- default to ./ rather than /www (if unspecified) for compatibility with
earlier versions.
- Allow ip: as a synomym for A: rules for compatibility with earlier
versions.
- Setting of CGI_ARGLIST_  when automatic setting of env vars for form
scripting is utilized.  This helps with minimal systems like openap.

so it doesn't hurt (adds compatibility though)

0b31586c71 A patch from Bart Visscher <magick@linux-fan.com> to add an
xconnect helper routine which does:
        -address and port resolving
	-tries to connect to all resolved addresses until connected
	-uses getaddrinfo, so works for IPv6 too
This patch also ports rdate, telnet, and wget to use the new
xconnect function.  Thanks Bart!
