[patch][BusyBox] Domain assignment support for SELinux/AppArmor/LIDS
Hello. We would like to suggest Secure OSes(such as SELinux/AppArmor/LIDS) domain assignment support for BusyBox. This work is done by Hiroshi Shinji. 1. Background Secure OSes such as SELinux, AppArmor and LIDS can assign domain to processes. Domain means set of access rights. Domain is assinged to processes at the time of exec system call. # This is a little similar to suid feature of Linux. For example, in the case of SELinux, /sbin/syslogd is assigned syslogd_t domain at the execution time of /sbin/syslogd. syslogd_t are allowed to read syslogd.conf, write log files, etc. However, current BusyBox does not suitable for assigning domains. Because BusyBox is a single file that is called through a lot of links. Secure OS treats /sbin/syslogd and /sbin/httpd as /bin/busybox. So, /sbin/syslogd and /sbin/httpd run as the same domain. Known solutions to this problem is preparing wrapper program that calls applet. For example, /sbin/syslogd is a small C program that calls /bin/busybox syslogd. Then, at the execution of /sbin/syslogd, syslogd_t domain is assigned and /bin/busybox syslogd is called and inherits assinged domain(syslogd_t). However, such wrapper consumes storage(more than 1k byte per wrapper). For detailed description about this problem, Yusuke Sato wrote documentation: http://www.selinux.gr.jp/LIDS-JP/LIDS_en/document/general/web_lids_busybox/main.html 2. Our solution Shinji came up with one idea. He thought script wrappper like below. If you enabled INSTALL_APPLET_SCRIPT_WRAPPERS, wrappers like below are installed. The contents of /sbin/syslogd is following. #!/bin/busybox It is only 15 byte. When /sbin/syslogd is executed, /bin/busybox /sbin/syslogd other arguments is called. To achive above, we had to modify applets.c - applet_name = argv[0]; - run_applet_and_exit(argv[0], argv); + applet_name = bb_get_last_path_component(argv[0]); + run_applet_and_exit(applet_name, argv); We tried the patch for SELinux and AppArmor. And domains were assigned sucessfully! 3. Limitation Programs that are used as interpreter can not be installed as script wrapper. It is due to limitation of exec(interpreter can not be called twice). For example, /bin/sh can not be installed as script wrapper. If /bin/sh is installed as script wrapper, shell scripts do not run. In interpreting #!/bin/sh - /bin/sh is #!/bin/busybox, - #! is called twice - exec system call fails(limitation of exec system call). In our patch, sh is installed as symlink or hard link by default (you can install it as script wrapper if you still need). Assigning domain is critical to secure OSes. We want way to assign to domains to busybox applets. Please review this patch and consider merging.

Re: Again, troubles with uploading files using busybox httpd
Hi Alexander! Your uploadconfig.cgi looks interesting, some months ago I also tried to handle form-based uploads in shell script, but felt it was too tricky and unstable. What if another browser sends more headers? Why read the uploaded file several times for line counting, head and tail operations? and so forth. [OT] I use httpd (currently BB 1.5.1) on a mipsel platform (embedded router system) in combination with Haserl (http://haserl.sourceforge.net/) as a CGI handler and am very satisfied. Maybe this is an option to be considered for you, too. The latest Haserl release 0.9.18 comes with an interesting new option which has been incorporated by the author upon my request: The upload is not stored as a temp-file, but written into a pipe (FIFO). A handler for reading the FIFO is called asynchronously, so a shell script can extract a tar archive on the fly, for example. This is an advantage on platforms with limited memory if you want to avoid double memory consumption (archive plus extracted content). And the best thing is that the upload is read once and only once. Haserl is lean and the very simple template mechanism integrates beautifully in shell scripts (or Lua scripts, if you prefer). BTW: No, I don't get money for promoting Haserl, I am just a satisfied user. ;-) [/OT] Back to your shell script: I think it would be better to develop a version which reads the content length header and then acts accordingly, not reading linewise, but bytewise, even though in your case you always seem to upload text files or maybe base64-encoded binaries. But don't forget that binary uploads are also allowed. So if you want a more general solution, you might have to improve your script considerably.

Rewritten autoconf and build directory
Hello all, I stumbled on a possible issue with today's svn edition of Busybox. There was no problem whatsoever to build Busybox 1.6.1 fresh out of the box into a separate build directory, but when I tried the same with svn trunk of today, the changed autoconf handling gives a warning and then an error is caused by applets/usage.c and include/applets.h, thus breaking an chance of progress early on. I am not sure whether the fault is mine or not, but I thought it best to point it out anyway. I will revert to 1.6.1 for the moment, since I have no time to spare in the near future.

[PATCH] Fix syslogd circular log buffer: head pointer not moved forward
Hello,
The following patch fixes the circular log buffer in syslogd. Currently the
head pointer is never moved forward. The 'logread' command will always read
from the beginning of the buffer, even if the log buffer wraps.
The head pointer is not moved forward because it is 0 by default, so the
comparison (old_tail shbuf-head) never evaluates to true.
I have only been able to test this patch on Busybox 1.4.2. I've included a
patch for 1.6.0 as well, if someone would please test and commit it. Thank you!
Regards,
Jari

use /proc for more of procps
Has anyone looked at using /proc entries for more of the functionality in the procps tools? For example, original procps's free command reports more stuff, such as the amount of memory used by cache. (Given the name PROCps it's a bit odd that eg free does not use /proc. Real procps's free certainly does.) thanks, Hamish -- Hamish Moffatt VK3SB [EMAIL PROTECTED] [EMAIL PROTECTED] ___ busybox mailing list busybox@busybox.net http://busybox.net/cgi-bin/mailman/listinfo/busybox
