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. egor

This patch makes msh handle variable expansion within backticks more correctly. Current behaviour (wrong): -------------------------- BusyBox v1.00-rc3 (2004.08.26-11:51+0000) Built-in shell (msh) Enter 'help' for a list of built-in commands. $ A='`echo hello`' $ echo $A `echo hello` $ echo `echo $A` hello $ New behaviour (correct): ------------------------ BusyBox v1.00-rc3 (2004.08.26-11:51+0000) Built-in shell (msh) Enter 'help' for a list of built-in commands. $ A='`echo hello`' $ echo $A `echo hello` $ echo `echo $A` `echo hello` $ The current behaviour (wrong according to standards) was actually my fault. msh handles backticks by executing a subshell (which makes it work on MMU-less systems). Executing a subshell makes it hard to only expand variables once in the parent. Therefore I export all variables that will be expanded within the backticks and let the subshell handle the expansion instead. The bug was found while searching for security leaks in CGI-scripts. Current behaviour of msh makes it easy to expand backticks by mistake in $QUERY_STRING. I recommend appling the patch before release of bb 1.00. /Jonas

This bug is in busybox 1.0.0-rc2. When using lash exec builtin with redirection, the opened file fd keep increasing. For example, please try the following command with lash. ls -al /proc/<lash pid>/fd exec /bin/sh 2>/dev/null ls -al /proc/<lash pid>/fd The last 'ls' command output will look like this. The fd number 4 shouldn't exist. lrwx------ 1 501 100 64 Aug 13 13:56 4 -> /dev/pts/5 l-wx------ 1 501 100 64 Aug 13 13:56 2 -> /dev/null lrwx------ 1 501 100 64 Aug 13 13:56 1 -> /dev/pts/5 lrwx------ 1 501 100 64 Aug 13 13:56 0 -> /dev/pts/5 dr-xr-xr-x 3 501 100 0 Aug 13 13:56 .. dr-x------ 2 501 100 0 Aug 13 13:56 . This one-line patch fix this problem by setting CLOEXEC flag for squirrel fd. Please apply. Joe.C

A question was posted a month ago by Mark Alamo to see if others had problems with sourcing subscripts within msh. We asked his firm to fix the msh.c bug he described because we didn't have enough time to do it ourselves. When msh.c is executing a compound statement and there is a . command to source another script file, msh.c will not execute the subscript until it's completed executing the rest of the compound statement. His example was this: Echo "Start" ; . ./subA; echo "mid" ; . ./subB ; echo "end" subA and subB execute AFTER end is printed in reverse order. The same is true if the sourced files are inside an if else fi, case esac, or any compound statement. Attached is a patch to msh.c. It fixes the problem. Cd to the root of your busybox tree and execute "patch -p1 < msh.c.patch" Unfortunately, I won't have more time to work on this so I hope that there aren't any problems!

With job control enabled, ash fails to tcsetpgrp back to initialpgrp upon exit. exitshell() should call setjobctl(0) to do this. Context: I am using a lightweight menu system (replimenu[.sf.net]) on my console, which invokes "/bin/sh -i -c /bin/login", where /bin/sh and /bin/login are busybox applets. /bin/sh is ash, with CONFIG_ASH_JOB_CONTROL=y as the sole suboption. The shell of the user concerned (nobody) is also /bin/sh (ash). When the user /bin/sh exits (and thereby login and its parent sh), replimenu receives EIO when it tries to read from the terminal.

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! - Larry

Just upgraded from 0.6 to 1.00-pre8 Dot command handling handled args correctly (same as bash) in 0.60, but failed in 1.00: I fixed this by reverting the dotcmd function back to previous 0.60 instantiation, please consider using the older version. Thanks Peter

It looks like latest uClibc defines ARCH_HAS_MMU, but a few busybox files test UCLIBC_HAS_MMU, resulting in vfork() getting called instead of fork(), etc. Patch below. Only tested for lash. Cheers, -Jamie

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 $
