Description Stephen Bosch 2005-02-11 20:44:53 UTC
When I try to emerge xmame, it builds successfully but fails when it tries to merge the built binaries.



Reproducible: Always
Steps to Reproduce:
1. ACCEPT_KEYWORDS="~x86" emerge -v xmame
Actual Results:  
/usr/bin/install -d    -o root -g bin -m  755
/var/tmp/portage/xmame-0.89/image//usr/share/man/man6
/usr/bin/install -c    -o root -g bin -m  444 doc/xmame.6
/var/tmp/portage/xmame-0.89/image//usr/share/man/man6/xmame.6
xmame for linux-i386 installation completed
 * A game was detected that is setuid root!
 * /var/tmp/portage/xmame-0.89/image///usr/games/bin/xmame.svgalib

!!! ERROR: games-emulation/xmame-0.89 failed.
!!! Function prepgamesdirs, Line 115, Exitcode 0
!!! refusing to merge a setuid root game
!!! If you need support, post the topmost build error, NOT this status message.



Expected Results:  
None of the binaries created should be setuid 'root'.

The binary in question is xmame.svgalib. Here is 
/var/tmp/portage/xmame-0.89/image/usr/games/bin:

Just curious... what if you try FEATURES="-sfperms" emerge xmame?
Comment 2 Stephen Bosch 2005-02-12 11:01:45 UTC
No dice, same result:

/usr/bin/install -d    -o root -g bin -m  755 /var/tmp/portage/xmame-0.89/image//usr/share/man/man6
/usr/bin/install -c    -o root -g bin -m  444 doc/xmame.6 /var/tmp/portage/xmame-0.89/image//usr/share/man/man6/xmame.6

Comment 3 SpanKY gentoo-dev 2005-02-12 11:19:56 UTC
with svgalib-0.9.x, we shouldnt need the binaries setuid root since the newer svgalib comes with a helper module specifically to allow non-root users access to the svga driver ... from the svga README:

Program using svgalib 1.9.0 or later don't need root provoleges (suid
root). They do need access to /dev/svga, which is a char device
with major 209 and minor 0.
The module svgalib_helper need also be inserted.

sfperms has nothing to do with this error, this is a sanity check i added to our games.eclass
