Description Dominik 'Rathann' Mierzejewski 2008-12-14 18:42:17 UTC

Sorry to bother you, but I made some changes to ffmpeg and x264 packages in RPMFusion devel branch and the fixes you made for these bugs: bug 469992, bug 470682, bug 471878 and bug 474402 are going to be obsolete, because I moved the libs from /usr/lib/sse2 to /usr/lib/i686. Could you please change the paths in selinux-policy accordingly?

Comment 1 Daniel Walsh 2008-12-15 16:25:56 UTC

Can't you just build the libraries correctly so they don't need text relocation then I don't have to make any SELinux changes.

Comment 2 Dominik 'Rathann' Mierzejewski 2008-12-15 18:41:35 UTC

Whether it's incorrect to have textrels or not is a subject for debate. ;)
Anyway, x264 has intentionally dropped support for PIC on x86_32, so no, I can't unless someone steps up and offers to maintain a patch adding it back. As for FFmpeg libs, patches are welcome and I can promise I'll work with upstream to get them accepted. Currently, if I force FFmpeg to build with -fPIC, it fails:
/builddir/build/BUILD/ffmpeg-20081214/libswscale/rgb2rgb_template.c: In function 'rgb24toyv12_MMX':
/builddir/build/BUILD/ffmpeg-20081214/libswscale/rgb2rgb_template.c:2221: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm'
/builddir/build/BUILD/ffmpeg-20081214/libswscale/rgb2rgb_template.c:2148: error: 'asm' operand has impossible constraints
[...]

and

Comment 3 Daniel Walsh 2008-12-15 20:28:26 UTC

Fixed in selinux-policy-3.5.13-35.fc10
