Hi, Please update selinux-policy packages to fix it. $ audit2allow -i avc #============= systemd_logind_t ============== #!!!! This avc is allowed in the current policy allow systemd_logind_t urandom_device_t:chr_file read; $ rpm -q selinux-policy selinux-policy-3.12.1-90.fc20.noarch |
Description of problem: SELinux is preventing /usr/lib/systemd/systemd-logind from 'read' accesses on the chr_file urandom. ***** Plugin catchall_boolean (47.5 confidence) suggests ****************** If you want to allow authlogin to nsswitch use ldap Then you must tell SELinux about this by enabling the 'authlogin_nsswitch_use_ldap' boolean. You can read 'None' man page for more details. Do setsebool -P authlogin_nsswitch_use_ldap 1 ***** Plugin catchall_boolean (47.5 confidence) suggests ****************** If you want to allow global to ssp Then you must tell SELinux about this by enabling the 'global_ssp' boolean. You can read 'None' man page for more details. Do setsebool -P global_ssp 1 ***** Plugin catchall (6.38 confidence) suggests ************************** If you believe that systemd-logind should be allowed read access on the urandom chr_file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep systemd-logind /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:systemd_logind_t:s0 Target Context system_u:object_r:urandom_device_t:s0 Target Objects urandom [ chr_file ] Source systemd-logind Source Path /usr/lib/systemd/systemd-logind Port <Unknown> Host (removed) Source RPM Packages systemd-208-2.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-84.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.11.3-301.fc20.x86_64 #1 SMP Thu Oct 3 00:57:21 UTC 2013 x86_64 x86_64 Alert Count 4 First Seen 2013-10-06 20:04:13 YEKT Last Seen 2013-10-09 23:17:49 YEKT Local ID 0c18a470-705b-4161-bbb0-3c254855e3ba Raw Audit Messages type=AVC msg=audit(1381339069.565:465): avc: denied { read } for pid=480 comm="systemd-logind" name="urandom" dev="devtmpfs" ino=1033 scontext=system_u:system_r:systemd_logind_t:s0 tcontext=system_u:object_r:urandom_device_t:s0 tclass=chr_file type=SYSCALL msg=audit(1381339069.565:465): arch=x86_64 syscall=open success=no exit=EACCES a0=7fe56d89381d a1=80100 a2=7fe56e6485c0 a3=0 items=0 ppid=1 pid=480 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=systemd-logind exe=/usr/lib/systemd/systemd-logind subj=system_u:system_r:systemd_logind_t:s0 key=(null) Hash: systemd-logind,systemd_logind_t,urandom_device_t,chr_file,read Additional info: reporter: libreport-2.1.7 hashmarkername: setroubleshoot kernel: 3.11.3-301.fc20.x86_64 type: libreport Potential duplicate: bug 1016190
