2005-05-26Tobias Krawutschke found a bug where the DHCP client would accept packetsRob Landley
with the wrong ARP address, meaning we could easily get somebody else's IP. That is a bad thing, and this is the minimal two-line fix.
2005-05-20Add readprofile applet support.Paul Mundt
2005-05-18Patch from Colin Watson (mangled slightly by Rob Landley):Rob Landley
This patch implements the 'T' command in sed. This is a GNU extension, but one of the udev hotplug scripts uses it, so I need it in busybox anyway. Includes a test; 'svn add testsuite/sed/sed-branch-conditional-inverted' after applying.
2005-05-18Doug Swarin pointed out a security bug in the -i option of sed.Rob Landley
While the permissions on the temp file are correct to prevent it from being maliciously mangled by passing strangers, (created with 600, opened O_EXCL, etc), the permissions on the _directory_ might not be, and we re-open the file to convert the filehandle to a FILE * (and automatically get an error message and exit if the directory's read-only or out of space or some such). This opens a potential race condition if somebody's using dnotify on the directory, deletes/renames the tempfile, and drops a symlink or something there. Somebody running sed -i as root in a world writeable directory could do damage. I dug up notes on an earlier discussion where we looked at the security implications of this (unfortunately on the #uclibc channel rather than email; I don't have a transcript, just notes-to-self) which pointed out that if the permissions on the directory allow other people's files to be deleted/renamed then the original file is vulnerable to sabotage anyway. However, there are two cases that discussion apparently didn't take into account: 1) Using another user's permissions to damage files in other directories you can't access (standard symlink attack). 2) Reading data another user couldn't otherwise access by having the new file belong to that other user. This patch uses fdopen to convert the filehandle into a FILE *, rather than reopening the file.

2005-05-15Tito pointed out I'd broken -t (argv[optind] can't be before getulflags),Rob Landley
and replaced the use of system() (and resulting security implications).
2005-05-14Add automatic umount support to eject command. Patch from Tito,Rob Landley
with tweaks from Mike Frysinger and Rob Landley. Note: this will still fail to umount a path that contains an ' or \ character. Is it worth the extra size to filter for that?

2005-05-09Patch from Shaun Jackman:Rob Landley
> This patch modfies expr to use portable POSIX regex rather than BSD > regex. ... > This updated patch implements an anchored regex by checking that the > match starts at offset 0. More to the point, this patch uses the same regex that sed.c is already using (opportunity to suck in less library code), and even building a dynamically linked busybox with just expr the result is a slightly smaller binary (by 94 bytes, I dunno what nm --size-sort has to say about it because I didn't build with debug info, since that changes the binary size a lot by disabling optimization...) Your mileage may vary. Handle with caution. Do not taunt happy fun ball.
2005-05-07Manuel points out that if printf needs a flush to act like dprintf, the resultRob Landley
is bigger. Revert last patch.
2005-05-07This one's from me. Fix ash "standalone shell".Rob Landley
If we exec /proc/self/exe and only fall back to /bin/busybox if /proc isn't there, then we have a reasonable chance of having the standalone shell work even if busybox isn't installed in /bin on the system in question. Still won't work in a chroot environment, but it's an improvement.
2005-05-07Shaun Jackman pointed out that dprintf(STDOUT_FILENO,...) is just a printf.Rob Landley

Patch from Takeharu Kato.
2005-05-04Revert the uptime() removal. Let the list sort it out...Rob Landley
2005-05-04Patch from Shaun Jackman:Rob Landley
Replace uptime with time(NULL). time is more portable than uptime and eliminates the need to define uptime, reducing code size slightly.
2005-05-04Takeharu Kato's patch added 2.6 support to lsmod; this changes menuconfigRob Landley
dependencies so 2.6 support depends on insmod or lsmod...
