The sed command in busybox 1.0.0-pre8 loses leading whitespace in 'a' command ('i' and 'c' commands are also affected). A patch to fix this is attached at the end of this message. The following is a transcript that reproduces the problem. The first run uses busybox 1.0.0-pre3 as "/bin/sed" command, which gets the expected result. Later in the test, /bin/sed symlink is changed to point at busybox 1.0.0-pre8 and the test script is run again, which shows the failure. === reproduction recipe === * Part 1. Use busybox 1.0.0-pre3 as sed; this works. root# cd /tmp root# cat 1.sh #!/bin/sh cd /tmp rm -f ipsec.conf ipsec.conf+ cat >ipsec.conf <<\EOF version 2.0 config setup klipsdebug=none plutodebug=none plutostderrlog=/dev/null conn %default keyingtries=1 ...

The problem is that the command argument parsing code strips leading whitespaces too aggressively. When running the above example, the piece of code in question gets "\n\tnat_traversal=yes" as its argument in cmdstr variable (shown part in the following patch). What it needs to do at this point is to strip the first newline and nothing else, but it instead strips all the leading whitespaces at the beginning of the string, thus losing the tab character. The following patch fixes this.

Ok. Last patch reduce 73 bytes for compensate (and over) your changes ;-) Comments: Added cin_fileno variable, auto setted to 0 from BSS and have "eq" stdin descriptor if isatty(stout)==0, removed global variable FILE* cin. Removed default setting to terminal_width/terminal_height, this used only from main() and setted after call get_terminal_width_height() always correct. Variable please_display_more_prompt changed to bits logic, have size reducing. --w vodz

I've noticed a bug in the "autowidth" feature more, and is probably in others. The call to the function get_terminal_width_height() passes in a file descriptor but that file descriptor is never used, instead the ioctl() is called with 0. In more_main() the call to get_terminal_width_height() passes 0 as the file descriptor instead of fileno(cin). This isn't a problem when you more a file (e.g. "more /etc/passwd") but when you pipe a file to it (e.g. "cat /etc/passwd | more") the size of the terminal cannot be determined because file descriptor 0 is not a terminal. The fix is simple, I've attached a patch for more.c and get_terminal_width_height.c. BAPper

2004-03-16Patch from vodz to fix the dynamic vars patch, which I should notEric Andersen
have checked in. Vladimir writes: Your patch have many problem. 1. You always added + time(). This cannot reset RANDOM=value for debuging with replay sequential. 2. Hmm. I examine bash 2.04 source. This pseudorandom generator use low bits of counter value. You use high bits. This make bad pseudorandom values after have 0-value. For example, if + time() do remove, your generator always return 0 after first generate 0. 3. Memory leak per call. Use ash-unlike unecessary bb_strdup function. 4. Unsupport show last $RANDOM value for "set" and "export" command. 5. Bloat code. Busybox-unlike patch - added unstandart feature as default hardcode. Last patch attached.

Here's a follow-up replacement to the patch I sent earlier, this adjusts some of the semantics of the dynamic variable setting. Namely, dynamic vars can hook a set handler (which RANDOM uses to adjust the seed). They'll only lose their dynamic status if they're unset. I've used the same approach that bash does to come up with the random number, mostly just for consistency. For example: $ echo $RANDOM 13759 $ echo $RANDOM 20057 $ echo $RANDOM 1502 $ export RANDOM=42 $ echo $RANDOM 24179 $ echo $RANDOM 2046 $ unset RANDOM $ echo $RANDOM $ export RANDOM=42 $ echo $RANDOM 42 $

2004-03-05Patch by Andrew Victor,Glenn L McGrath
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).
