Here is a patch against the current subversion repository, that makes
udhcpc have an adjustable timeout. Works for both foreground and before
it drops to the background. This brings it more in-line with ISC dhcpc.
Use like so:
udhcpc --timeout=10 ...
or
udhcpc -T 10 ...
Still shooting for 1.1.1 this month? Would really be great if you could
get this in that release.

* coreutils.h: remove prototype of non-existing xgetoptfile_sort_uniq
and add boilerplate.
* networking/{ipaddr,ip,iplink,iproute,iptunnel}.c: touch includes
and use short boilerplate.
* libiproute/iproute.c: rename round to avoid clashes with older
SuSE gcc and use short boilerplate.

Ping packets sent by busybox have wrong endian on f.x. mips32 (openwrt). Attatched is a patch that
uses htons() and ntohs() to be platform independent.
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.)
We were seeing some timeouts when getting files with the busybox tftp
client.
With tcpdump, we saw that the tftp client was receiving blocks and
ack'ing them, but the server was failing to receive the occasional
ack.
When that happened, the server would send the last block over again,
but the tftp client was expecting the next block.
This patch allows the client to recover from this situation
(it sends an ack for the repeat block but does not write it
to the local file).
I hope it meets your approval, please don't hesitate to send
me comments for improvement.
The patch is against "head" in svn, I tested it on an older version
of busybox in our environment. It applied cleanly to the older
version.
Credit for this goes to my co-worker John McCarthy for finding
it and me for fixing it (assuming it works for everyone else too).

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.

BTW: I've ripped out a lot of debug code and changed c++ // comments to /* */
as both were rather confusing for a newbie like me. ;-)
Sorry to the author for that.
I know that this makes mantaining the code easier, but I'm simple minded....
Hello,
Here's a patch for a first attempt at static leases for udhcpd.
Included in the tarball are 2 files (static_leases.c, static_leases.h)
and a patch against the latest cvs.
In the config file you can configure static leases with the following
format:
static_lease 00:60:08:11:CE:4E 192.168.0.54
static_lease 00:60:08:11:CE:3E 192.168.0.44
Comments/suggestions/improvements are welcome.

Ok.

Hi!
I've created a patch to busybox' build system to allow building it in
separate tree in a manner similar to kbuild from kernel version 2.6.
That is, one runs command like
'make O=/build/some/where/for/specific/target/and/options'
and everything is built in this exact directory, provided that it exists.
I understand that applyingc such invasive changes during 'release
candidates' stage of development is at best unwise. So, i'm currently
asking for comments about this patch, starting from whether such thing
is needed at all to whether it coded properly.
'make check' should work now, and one make creates Makefile in build
directory, so one can run 'make' in build directory after that.
One possible caveat is that if we build in some directory other than
source one, the source directory should be 'distclean'ed first.

Ok, Ok. I should find time to understand with a problem.

"I have a need to _really_ know if the interface was properly configured
via ifup so I made busybox's ifupdown pass the return codes through rather
than dropping them on the floor."
"All the functions in ifupdown.c return 1 on success and 0 on failure
(which happens to the opposite of standard practices but whatever).
So it is important for all these functions to not blindly return 1."
"The problem with blindly returning ret, even if it is != 1, is the
callers expect a 0 or 1 and accumulate the return codes. So a function that
makes 3 calls to execute will have a value of 3 accumulated. That value
of 1 (success) was almost always returned even if 1 of the commands in the
command sequence failed. The attached patch fixes the lack of checking
to verify thar result == expected_reult."
Hi,
Package: BusyBox
Version: 1.0.0-pre10
When an incomplete read or write from/to a local file occurs (i.e.
not an EOF condition), the tftp client prematurely exits. This
problem can be reproduced by slowly piping data to the tftp client
like this:
(for v in 1 2 3; do echo $v; sleep 1; done) | \
tftp -p -l - -r output.txt <host>
The output file on the TFTP server will contain "1".
The attached patch provides a possible solution to this problem.
I can reproduce this on ARM sa1110 and ARM xscale boards, both
running Linux-2.6.4 & glibc-2.3.2. Thanks for the wonderful
program!

Updated patch: get rid of syslog_msg entirely. Request from Erik Andersen.

Passing the -q <integer> option to inetd causes it to dereference an

Hello,
Last November a bug was found in iproute. CAN-2003-0856 has more information.
Basically, netlink packets can come from any user. If a program performs action
based on netlink packets, they must be examined to make sure they came from the
place they are expected (the kernel).
Attached is a patch against pre8. Please apply this before releasing 1.00 final.
All users of busy box may be vulnerable to local attacks without it.

Hi,
the following output is from BusyBox 1.0.0-pre10:
~ # ip link help
ip: Command "help" is unknown, try "ip link help".
tk
This patch fixes it by removing the advertisements for
the "ip blah help" stuff that is not implemented.
This is a bulk spelling fix patch against busybox-1.00-pre10.
If anyone gets a corrupted copy (and cares), let me know and
I will make alternate arrangements.
Erik - please apply.
Authors - please check that I didn't corrupt any meaning.
Package importers - see if any of these changes should be
passed to the upstream authors.
I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.
What is "pretect redefined for test" in cmdedit.c?
Good luck on the 1.00 release!

In arpping.h, fix structure alignment of "struct arpMsg".
GCC can insert padding in the structure which causes udhcpd to send an
invalid ARP packet on the network. It will then not receive a valid
reply, which can cause it to assign an IP address that's already in use
on the network.
(With kernels before 2.4.20, the "struct ethhdr" in linux/if_ether.h
wasn't marked as packed. This is also an issue if your toolchain was
built with a pre-2.4.20 kernel).
Hi,
When downloading files over slow network (e.g. wireless/
internet) using IE, sometimes it will stop downloading and
show error message 'connection closed' when the download
is almost complete. This is because IE can't handle server
close connection properly.
Apache http_main.c fix this problem by close the connection
after client close the connection. This patch do exactly the
same thing. Please consider include this patch.

Hi,
Well, I made this patch a long time ago (08/2002) because it was a
need of a project, but had no time to send it to you. It adds support
to `autologin' option of the telnet protocol. It has been used since
made with busybox 0.60.3 at production and I had no problems with it.
I have ported it to the HEAD revision of the CVS server (20040211) and
I hope you enjoy and apply it to the official sources. :)
Thanks a lot!
The config file processing for inetd in busybox-1.00-pre7 and newer
is broken -- the saved command argv[] values overwrite each other.
Patch to fix it is attached.
Cheers

Hi,
When httpd connection is closed, bosybox httpd will
not stop reading from CGI program. This patch fix this
problem. It check the return value of bb_full_write and
stop reading from CGI if the connection is closed.
Please apply this patch.

uuencode fails to encode binary data because it right-shifts
bytes as signed chars and keeps the duplicated sign bits.
The original base64_encode() from wget/http.c is broken as well,
but it is only used to encode ascii data.
