hello
i had some trouble with the filedescriptor in udhcp.
Two things happened on my device:
1.) broken or not connected cable (no dhcp-server)
2.) daemonizing (starting with option -b)
i got a filedescriptor fd=0 from function raw_socket,
after daemonizing (daemon call) the fd is closed.
Client can't recieve data's anymore.
i fixed this problem (like pidfile handling):
in order to fix the problems with round robin DNS reported
by Andrew Flegg:
http://busybox.net/lists/busybox/2003-October/009579.html
This removes the ipv6 specific xconnect dns lookups. I do
not see why that would need to be special cased for ipv6 as
was done, but that will just have to be tested.
So IPV6 people -- please test this change!

the busybox menuconfig triggered my "inacceptable number of spelling mistakes"
upper level, so I decided to make a patch ;-)
I also improved some wording to describe some things in a better way.
Many thanks for an incredible piece of software!

- env vars CONTENT_TYPE, CONTENT_LENGTH, HTTPD_REFERER, REMOTE_USER and
AUTH_TYPE(Basic always).
- POST data pipied now (previous version have loading into memory may be
big size data and reducing with hardcoded limit)
- removed $CGI_foo environment variables, else my have rubbish
enviroment if POST data have big binary file
- Can`t use 255.255.255.255 address
- typo: double check for valid ip address and uncheck for valid mask
httpd unseted SERVER_PORT (my bug from last_patch111).

Thanks. Unfortunately there was one small bug in that last patch.
Could you apply this one as well?
p.
Busybox`s httpd have the defect (from born):
ip 1.2.3.1 have true comparing also with
1.2.3.10-1.2.3.19 and 1.2.3.100-1.2.3.199.
Last patch removed this bug and added feature:
allow/deny rule can support network/netmask
example: 1.2.3.0/255.255.255.128
or
network/mask_bits
example: 1.2.3.0/25
now; old format

1.2.3
1.2.3.4
too support and converted to
1/8 1.2/16 1.2.3/24 1.2.3.4/32
automaticaly.
Also, current CVS have small problem: ignores
A:IP, (loses 'A', 'a' only work). Corrected.
of netmasks. It also fixes the parameters for network and netmask to match
that of the official Red Hat version (-n for network and -m for netmask).

I reworked the logic in his patch
The attached patch adds "mtu" and "hwaddress" to the inet6 method and
"mtu", "hwaddr" and "pointopoint" to the inet4 method (just like in
the ifupdown part).
Note: "hwaddress" can't be used with the busybox ip applet (this
function isn't implemented in bb ip yet), but it can be of use with
an external "full blown" ip package.
The patch also removes "label" from the loopback configuration,
labels (subinterfaces) aren't used with loopback interfaces.
It further solves a problem in the bootp method, "ifconfig down
%interface%" should be "ifconfig %interface% down" and it's now also
possible to use ip with bootp.
The patch is fully tested with both busybox ip and "stand-alone" ip
and I didn't saw any problems.
The recent changes in ifupdown where all calls to 'ip link set' and
'ip addr set' are swapped give some problems with v4tunnels.
For plain ipv4 and ipv6 interfaces it works correct, other methods
not tried. The patch below change the behaviour back for v4tunnels
only.
Without the patch the following errors are shown:
RTNETLINK answers: Network is down
RTNETLINK answers: No route to host
and the tunnel is not fully brought up
With this patch all works as expected.
this patch fixes run_parts when it's called by ifupdown. 1) argv has to be a
NULL terminated char* array, not just a string. 2) run_parts now explicitly
sets the environment. this environment is populated from the
/etc/network/interfaces config file and is needed by the scripts in
/etc/network/if-pre-up.d/. when run-parts is called from the command line the
environment is taken from the current process.

You can simplify this if use:

Hi.
Last patch have new libbb function
vfork_rexec() for can use daemon() to uClinux system.
This patched daemons: syslog, klogd, inetd, crond.
This not tested! I havn`t this systems.
Also. Previous patch for feature request MD5 crypt password for
httpd don`t sended to this mailist on 07/15/03
(mailist have Pytom module problem?).
The previous patch included, and have testing.

Hello all,
This patch adds more "Help" text to the config system. Almost
all applets now have a help entry. Also, I cleaned up the spacing of
the existing text so that things are consistent. This patch is against
this morning's CVS.

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.
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.

Hello, I think the test for an unconfigured httpd is wrong in
the CVS (busybox-unstable-20030620.tar.bz2)
flg_deny_all is default 0

Oops. You are right.
Also, this mistake haved from two place.
Last patch rewroted to my new get_ularg() function for overcompensate size
from this error found ;-)
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.

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.
- ip route flush
- different usage for telnetd in inetd mode
- changes for the default flags of the ip features
- if no /usr requested, udhcpc should use the script also without /usr.
- this is consistent with IPv6 route
- you can get very confused, if there are no routes and "route" prints
nothing at all (not even "No routes" message)
modified Kbuild system I put into uClibc. With this, there should be no more
need to modify Rules.mak since I've moved all the interesting options into the
config system. I think I've got everything updated, but you never know, I may
have made some mistakes, so watch closely.

Ok. I generate patch for include to busybox-devel my work with
top (original author give me maintaining) and telnetd (my
support and unofficial maintaining) applets. Docs changes
also: added awk, netstat, time applets to list ;)
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!
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!
Fixed up domain removal for local domains. GNU traceroute does not do this. I
don't know why we do. Fixed incorrect argument for reverse resolution. Clean
up cruft that appears when CONFIG_FEATURE_TRACEROUTE_VERBOSE is defined
1. busybox-telnet dosn't inform server about the size of terminal screen.
In the world of xterminals and frame buffers it's rather horrible
to use fixed 80x24 region in upper-left corner of screen/window.
2. If client sends character 0x0d to the server then sends character 0x0a
the server eat the second byte (0x0a) - it's described in telnet RFC.
Client should send two bytes ( 0x0d + 0x0a or 0x0d + 0x00 ) insted of
one 0x0d byte.
3. busybox telnet implementation wasn't 8bit clean (look at 0xff byte).
I need it because I have to use binray transfer like rz/sz. So when
I resloved the problem (2) I corrected this one two.
This also contains a small cleanup patch from vodz, and some minor editing
by me.
the busybox development tree. This eliminates the use of recursive make, and
once again allows us to run 'make' in a subdirectory with the expected result.
And things are now much faster too. Greatly improved IMHO...

- Switched to getopt argument parsing
- Added -f option to get fully qualified domain name
- Fixed the -s (short) and -d (domain) options, which were not
doing a gethostbyname lookup to get the FQDN before trying to
separate the local and domain portions of the hostname.
- Fixed probem with 'agressive setting' of the hostname...the
previous busybox version would try to set the hostname if called
with a non-option argument, or the -F option, even if another
option (like -i or -s) was given. This behavior does not match
the net-tools hostname, which does not attempt to set anything if
given a 'display' option, regardless of the presence/absence of
the -F option or additional command line arguments.
- When using a file to set the hostname, behavior now matches
net-tools version...previous busybox version did not handle
comments, and simply grabbed the first line from the file.
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).
make busybox be more uClinux friendly. I also adjusted Config.h for
uClinux so it will automagically disable apps the arn't going to
work without fork() and such.

1) ping cleanup (compile fix from this patch already applied).
2) traceroute call not spare ntohl() now (and reduce size);
3) Fix for functions not declared static in insmod, ash, vi and mount.
4) a more simple API cmdedit :))
5) adds "stopped jobs" warning to ash on Ctrl-D and fixes "ignoreeof" option
6) reduce exporting library function index->strchr (traceroute), bzero->memset (syslogd)
- support for ftp downloads
- HTTP basic authentication support (as an optional feature)
- handling of http redirections
- protocol version changed to 1.0 (to stop servers from requesting
chunked encoding)
- bugfix: in the case when content-length not given, wget didn't
download anything
- when attempting to continue an aborted download but server doesn't
support restarts, reopen output file in write mode
- changed assumption that existing file should restart an aborted
download. Now the user must explicitly specify this with -c
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.
-Erik
- style changes
- It actually returns the code computed by INET_setroute (wasn't being done
properly before)
- The displayroute() format string now matches net-tools
busybox.h which slowed compiles. I left only what was needed and then fixed up
all the apps to include their own header files. I also fixed naming for pwd.h
and grp.h functions. Tested to compile and run with libc5, glibc, and uClibc.

exit().
Note that calling perror() after gethostbyname() will most likely return
"No such file or directory" which is quite confusing, so I decided to use
fatalError instead.

* cp/mv now accepts (and ignores) the -f flag, since it always
does force anyway
* tail can now accept -<num> commands (e.g. -10) for better
compatibility with the standard tail command
* added a simple id implementation; doesn't support supp. groups yet
