Description of problem: While trying to build a package for modem-manager-gui I stumbled upon this problem. Well, I could try to ship a SElinux exception rule with the package, but maybe this could be solved upstream. Don't know this access is critical in terms of security. SELinux is preventing /usr/sbin/ModemManager from 'read' accesses on the chr_file urandom. ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If sie folgendes tun möchten: allow global to ssp Then sie müssen SELinux darüber benachrichtigen, indem Sie die boolesche Variable »global_ssp« aktivieren. Für weitere Einzelheiten, können Sie die »None« man-Seiten konsultieren. Do setsebool -P global_ssp 1 ***** Plugin catchall (11.6 confidence) suggests ************************** If sie denken, dass es ModemManager standardmässig erlaubt sein sollte, read Zugriff auf urandom chr_file zu erhalten. Then sie sollten dies als Fehler melden. Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen. Do zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen: # grep ModemManager /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:modemmanager_t:s0 Target Context system_u:object_r:urandom_device_t:s0 Target Objects urandom [ chr_file ] Source ModemManager Source Path /usr/sbin/ModemManager Port <Unknown> Host (removed) Source RPM Packages ModemManager-1.1.0-2.git20130913.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-106.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.12.5-302.fc20.x86_64 #1 SMP Tue Dec 17 20:42:32 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-12-28 12:29:53 CET Last Seen 2013-12-28 12:29:53 CET Local ID 2a22704f-dce1-47d8-97ea-16821b5a6491 Raw Audit Messages type=AVC msg=audit(1388230193.358:663): avc: denied { read } for pid=436 comm="ModemManager" name="urandom" dev="devtmpfs" ino=6025 scontext=system_u:system_r:modemmanager_t:s0 tcontext=system_u:object_r:urandom_device_t:s0 tclass=chr_file type=SYSCALL msg=audit(1388230193.358:663): arch=x86_64 syscall=open success=no exit=EACCES a0=38d68bdd5c a1=0 a2=1b6 a3=1 items=0 ppid=1 pid=436 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=ModemManager exe=/usr/sbin/ModemManager subj=system_u:system_r:modemmanager_t:s0 key=(null) Hash: ModemManager,modemmanager_t,urandom_device_t,chr_file,read Additional info: reporter: libreport-2.1.10 hashmarkername: setroubleshoot kernel: 3.12.5-302.fc20.x86_64 type: libreport
