Martin, a bit of fun ahead. Hans, a bit of fun ahead.[1] [1] https://fedoraproject.org/wiki/Changes/XorgWithoutRootRights#Dependencies (In reply to Martin Kolman from comment #2) > Hans, a bit of fun ahead.[1] > > [1] https://fedoraproject.org/wiki/Changes/XorgWithoutRootRights#Dependencies That has not landed yet, so whatever is going on here it is not caused by this. Disabling SELinux on Rawhide nightlies allows initial-setup to run (both GUI and Text). (In reply to Paul Whalen from comment #4) > Disabling SELinux on Rawhide nightlies allows initial-setup to run (both GUI > and Text). Well, that looks like a bug in the SELinux policy on ARM, so reassigning. Could you attach AVC msgs from permissive mode? # setenforce 0 re-test # ausearch -m avc -ts recent ausearch -m avc

Is what i get on an arm ssystem
execmod indicates /usr/lib/libgcrypt.so.20.0.1 is built incorrectly. Meaning it is not built with PIE and PIC? execmod is explained below http://www.akkadia.org/drepper/selinux-mem.html #============= policykit_t ============== #!!!! This avc is allowed in the current policy allow policykit_t urandom_device_t:chr_file { read open }; policykit_t is allowed to read urandom_device_t in Rawhide. rpm -q selinux-policy selinux-policy-3.13.1-46.fc21.noarch I'll fix it.

disable non-PIC asm on armv7hl
OK, I've fixed this. We need to disable camellia, cast5, and rijndael ARM asm right now, as those files are written in a non-PIC way. I'll look at fixing these upstream, but in the meantime we can just fallback to C.
Fixed and re-enabled in 1.6.1-4 |
