Are you able to reproduce it? This will a race condition between the kernel creating the device, colord reading it and udev fixing the label. We might have to add a big dontaudit for these, as I think they are succeeding on the second try.
dontaudit domain device_t:chr_file { read open };
Yes. Lets just add, dontaudit colord_t device_t ...

SELinux is preventing /usr/libexec/colord from 'read' accesses on the chr_file 013. ***** Plugin device (91.4 confidence) suggests ***************************** If you want to allow colord to have read access on the 013 chr_file Then you need to change the label on 013 to a type of a similar device. Do # semanage fcontext -a -t SIMILAR_TYPE '013' # restorecon -v '013' ***** Plugin catchall (9.59 confidence) suggests *************************** If you believe that colord should be allowed read access on the 013 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 colord /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:colord_t:s0-s0:c0.c1023 Target Context system_u:object_r:device_t:s0 Target Objects 013 [ chr_file ] Source colord Source Path /usr/libexec/colord Port <Unknown> Host (removed) Source RPM Packages colord-0.1.7-1.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.16-23.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 2.6.38.5-24.fc15.x86_64 #1 SMP Fri May 6 08:00:28 UTC 2011 x86_64 x86_64 Alert Count 1 First Seen Mon 09 May 2011 06:22:45 PM EDT Last Seen Mon 09 May 2011 06:22:45 PM EDT Local ID d74d0f72-c414-457a-a027-238f5b6ad37e Raw Audit Messages type=AVC msg=audit(1304979765.999:22): avc: denied { read } for pid=1131 comm="colord" name="013" dev=devtmpfs ino=19690 scontext=system_u:system_r:colord_t:s0-s0:c0.c1023 tcontext=system_u:object_r:device_t:s0 tclass=chr_file type=AVC msg=audit(1304979765.999:22): avc: denied { open } for pid=1131 comm="colord" name="013" dev=devtmpfs ino=19690 scontext=system_u:system_r:colord_t:s0-s0:c0.c1023 tcontext=system_u:object_r:device_t:s0 tclass=chr_file type=SYSCALL msg=audit(1304979765.999:22): arch=x86_64 syscall=open success=yes exit=EEXIST a0=7ffff3459d60 a1=0 a2=7ffff3459d74 a3=0 items=0 ppid=1 pid=1131 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=colord exe=/usr/libexec/colord subj=system_u:system_r:colord_t:s0-s0:c0.c1023 key=(null) Hash: colord,colord_t,device_t,chr_file,read audit2allow #============= colord_t ============== allow colord_t device_t:chr_file { read open }; audit2allow -R #============= colord_t ============== allow colord_t device_t:chr_file { read open };
