It appears to be a legit access. From the quagga source:
$ find -type f | xargs grep /dev/urandom
./babeld/kernel.c:/* If /dev/urandom doesn't exist, this will fail with ENOENT, which the
./babeld/kernel.c: fd = open("/dev/urandom", O_RDONLY);

Description of problem: zebra appears to want to access /dev/random, and this generates AVCs. SELinux is preventing /usr/sbin/zebra from 'read' accesses on the chr_file random. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that zebra should be allowed read access on the random 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 zebra /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:zebra_t:s0 Target Context system_u:object_r:random_device_t:s0 Target Objects random [ chr_file ] Source zebra Source Path /usr/sbin/zebra Port <Unknown> Host (removed) Source RPM Packages quagga-0.99.22.1-7.fc19.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-65.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.9.9-302.fc19.x86_64 #1 SMP Sat Jul 6 13:41:07 UTC 2013 x86_64 x86_64 Alert Count 3 First Seen 2013-07-21 11:44:13 BST Last Seen 2013-07-22 16:30:24 BST Local ID 263cebce-16c7-4053-b738-197bfb69c353 Raw Audit Messages type=AVC msg=audit(1374507024.71:2271): avc: denied { read } for pid=31091 comm="ripd" name="random" dev="devtmpfs" ino=6728 scontext=system_u:system_r:zebra_t:s0 tcontext=system_u:object_r:random_device_t:s0 tclass=chr_file type=SYSCALL msg=audit(1374507024.71:2271): arch=x86_64 syscall=open success=no exit=EACCES a0=7f00f8312c1b a1=900 a2=7973 a3=7fff6d190c90 items=0 ppid=1 pid=31091 auid=4294967295 uid=92 gid=92 euid=92 suid=92 fsuid=92 egid=92 sgid=92 fsgid=92 ses=4294967295 tty=(none) comm=ripd exe=/usr/sbin/ripd subj=system_u:system_r:zebra_t:s0 key=(null) Hash: zebra,zebra_t,random_device_t,chr_file,read Additional info: reporter: libreport-2.1.5 hashmarkername: setroubleshoot kernel: 3.9.9-302.fc19.x86_64 type: libreport
