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.

Manuel,
I rewrite bb_getopt_ulflags() function for more universal usage.
My version support now:
- options with arguments (optional arg as GNU extension also)
- complementaly and/or incomplementaly and/or incongruously and/or list
options
- long_opt (all applets may have long option, add supporting is trivial)
This realisation full compatibile from your version.
Code size grow 480 bytes, but only coreutils/* over compensate this size
after using new function. Last patch reduced over 800 bytes and not full
applied to all. "mkdir" and "mv" applets have long_opt now for demonstrate
trivial addition support long_opt with usage new bb_getopt_ulflags().
Complementaly and/or incomplementaly and/or incongruously and/or list options
logic is not trivial, but new "cut" and "grep" applets using this logic
for examples with full demostrating. New "grep" applet reduced over 300
bytes.
Mark,
Also. I removed bug from "grep" applet.
$ echo a b | busybox grep -e a b
a b
a b
But right is printing one only.

problem with syslogd logging the '<' char.

The attached patch fixes a compilation error. If you compile ping6 without
the CONFIG_FEATURE_FANCY_PING6 option then the compile will fail without this
patch.

- 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.

'>' charactor can be logged, per rfc3164.
Also, a small patch from me to fix it so we use MAXLINE when allocating the
buffer, which is consistant with use everywhere else. This is needed since
uClibc defines BUFSIZE as 255, causing lines to be truncated at 255...

over the years. Well I finally took the time to track this down. It turns out
that inside linux/kernel/sys.c the kernel will call
machine_halt();
do_exit(0);
when halting, or will call
machine_power_off();
do_exit(0);
during a reboot. Unlike sysv init, we call reboot from within the init
process, so if the call to machine_halt() or machine_power_off() returns, the call to do_exit(0) will cause the kernel to panic. Which is a very
bad thing to happen.
So I just added this little patch to fork and call the reboot
syscall from within the forked child process, thereby neatly
avoiding the problem.
But IMHO, both calls to do_exit(0) within linux/kernel/sys.c
are bugs and should be fixed.
