Hi bb list, I'm working on my first embedded system, using Gentoo and of course busybox [1]. The complete root fs is placed in initramfs. During my work on this I stumbled about two things, which could be bugs of bb:
1.) I use an initialization script, which is called by init. This script starts with this: #!/bin/sh # Copyright 2006-2007 Gentoo Foundation # Distributed under the terms of the GNU General Public License v2 # Ensure we are called by init echo "PPID = $PPID" #[ "$PPID" == "1" ] || exit 0 I would expect a PPID of 1, bit I get something like 833! But if a check with ps, init has PID of 1?! I cannot explain this. I also used sysvinit instead of bb init and checked PPID in a similar way and got the same result! The only idea I have, where this could come from is, that /bin/sh is of course a link to /bin/busybox. Perhaps this breaks checking PPID? Or this is some kind of bug? Or is this related with running a system in rootfs of initramfs? 2.) There seems to be a bug in bb grep. I did this on my machine: hive ~ # busybox grep -Fow usbfs /proc/filesystems Segmentation fault hive ~ # busybox grep -Fo usbfs /proc/filesystems Segmentation fault hive ~ # busybox grep -F usbfs /proc/filesystems nodev usbfs hive ~ # busybox grep -o usbfs /proc/filesystems usbfs hive ~ # busybox grep -w usbfs /proc/filesystems nodev usbfs hive ~ # busybox grep -ow usbfs /proc/filesystems usbfs hive ~ # busybox grep usbfs /proc/filesystems nodev usbfs The first two should certainly not result in a Segmentation fault, right? Thanks for busybox. It is really great!
