SELinux is preventing /usr/sbin/ldconfig from 'read' accesses on the chr_file /dev/urandom.

Description of problem: I resumed my computer and this popped up. SELinux is preventing /usr/sbin/ldconfig from 'read' accesses on the chr_file /dev/urandom. ***** Plugin catchall_boolean (89.3 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 (11.6 confidence) suggests *************************** If you believe that ldconfig 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 ldconfig /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:ldconfig_t:s0 Target Context system_u:object_r:urandom_device_t:s0 Target Objects /dev/urandom [ chr_file ] Source ldconfig Source Path /usr/sbin/ldconfig Port <Neznámé> Host (removed) Source RPM Packages glibc-2.17-11.fc19.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-65.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive 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 1 First Seen 2013-07-19 18:04:57 CEST Last Seen 2013-07-19 18:04:57 CEST Local ID f5f7c181-6c74-4578-a8cb-f293e2b67a3d Raw Audit Messages type=AVC msg=audit(1374249897.171:326): avc: denied { read } for pid=8573 comm="ldconfig" path="/dev/urandom" dev="devtmpfs" ino=1033 scontext=system_u:system_r:ldconfig_t:s0 tcontext=system_u:object_r:urandom_device_t:s0 tclass=chr_file type=SYSCALL msg=audit(1374249897.171:326): arch=x86_64 syscall=execve success=yes exit=0 a0=23d8b10 a1=23d8c10 a2=23d75f0 a3=0 items=0 ppid=8571 pid=8573 auid=4294967295 uid=1000 gid=1000 euid=1000 suid=1000 fsuid=1000 egid=1000 sgid=1000 fsgid=1000 ses=4294967295 tty=(none) comm=ldconfig exe=/usr/sbin/ldconfig subj=system_u:system_r:ldconfig_t:s0 key=(null) Hash: ldconfig,ldconfig_t,urandom_device_t,chr_file,read Additional info: reporter: libreport-2.1.5 hashmarkername: setroubleshoot kernel: 3.9.9-302.fc19.x86_64 type: libreport
This is s a leaked file descriptor. Some tool had an open read fd to /dev/urandom and then executed ldconfig. Added dontaudit rules for this into git. c168faac729de9e68f46980b7f978d190c003462
It seems that it is related to connecting to network. I see it on two different notebooks, after I resume and the network is re-connected, every time.
c168faac729de9e68f46980b7f978d190c003462 I just added dontaudit for all device nodes leaked into ldconfig, since this happens too frequently.
