infrastructure, the compiler isn't smart enough to replace const static
int with the constant, and allocates space for each set of them,
bloating the executable something fierce. Oops.
So now, we #define ENABLE_XXX to 0 or 1 for each CONFIG_XXX (which
is still there so the 1000+ #ifdef/#ifndef tests don't have to be
replaced wholesale). Changed the test instance in networking/ifconfig.c
to use this.
Rob Landley, and others.
Currently CONFIG options are defined or undefined, so we chop out code with
#ifdefs, ala:
#ifdef CONFIG_THING
stuff();
#endif
This creates a new header file, bb_config.h, which sets the CONFIG entry to 1
or 0, and lets us do:
if(CONFIG_THING) stuff();
And let the compiler do dead code elimination to get rid of it. (Note: #ifdef
will still work because for the 1 case it's a static const int, not a #define.)

Wrap sockaddr_in6 in a ifdef CONFIG_FEATURE_IPV6.
Include sys/types.h instead of asm/types.h.
Include netinet/if_ether.h instead of linux/if_ether.h
The ioctl request argument is an int, not an unsigned short.
I noticed a problem with ifconfig in busybox 0.60.5. The matching code
seems to exist in busybox CVS as well, so I'll paste in the patch that
fixed it.
I was running:
# ifconfig wan0 1.2.3.4 pointopoint 1.2.3.5 netmask 255.255.255.255
I was seeing the inet addr and P-t-P addr both being set to 1.2.3.5
(the pointopoint address).
wan0 Link encap:Point-Point Protocol
inet addr:1.2.3.5 P-t-P:1.2.3.5 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MTU:1500 Metric:1
...
The patch below seems to fix it.
IPV6 support to busybox. This patch does the following:
* Add IPv6 support to libbb
* Enable IPv6 interface address display
* Add IPv6 config option
* Adds ping6, an adaptation of the ping applet for IPv6
* Adds support routines for ping6:
- xgethostbyname2
- create_icmp6_socket
* Adds ifconfig support for IPv6
* Add support IPv6 to netstat
* Add IPv6 support to route
Thanks Bart!
-- reverse resolve network name and cache in route and ifconfig
applets, fix print nslookup server name if compile without
uClibc, fix route crashe 'route add', fix warnings compile
networking and pwd_grp applets
by ifconfig that someone had submitted. It fixes 1 bug, gets rid of the
excessive bloating of a structure that is used in a static const array,
and removes the implicit struct copys by keeping only the int type needed.
It also turns this into a configurable feature (off by default).
hacking on the mess in net-tools-1.59, but it currently adds 12k and
supports ethernet, loop, ppp, and treats everything else as a generic
interface. Works ok for me.
