Miroslav I am thinking we may want to allow this for can_network? selinux-policy-3.12.1-180.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/selinux-policy-3.12.1-180.fc20 Package selinux-policy-3.12.1-180.fc20: * should fix your issue, * was pushed to the Fedora 20 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing selinux-policy-3.12.1-180.fc20' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2014-9454/selinux-policy-3.12.1-180.fc20 then log in and leave karma (feedback). The SELinux warning disappeared now - works for me, thanks! After installing the latest updates (I suppose kernel-3.15.10-200.fc20.x86_64 etc.)the SELinux error appears again. I'm further investigating, please don't close the bug yet, thanks. selinux-policy-3.12.1-180.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report. |
Description of problem: This starts to happen with the DNSSEC/TLSA Validator 2.1.1 Plugin for Firefox. Although not directly related, I suppose it is logical that browsers have certain access to DNS validation - more so in the future. Not sure whether this tool does it right, though... SELinux is preventing /usr/lib64/firefox/plugin-container from 'name_bind' accesses on the udp_socket . ***** Plugin bind_ports (54.8 confidence) suggests ************************ If you want to allow /usr/lib64/firefox/plugin-container to bind to network port 13030 Then you need to modify the port type. Do # semanage port -a -t -p udp 13030 ***** Plugin mozplugger (41.2 confidence) suggests ************************ If you want to use the plugin package Then you must turn off SELinux controls on the Firefox plugins. Do # setsebool -P unconfined_mozilla_plugin_transition 0 ***** Plugin catchall_boolean (4.84 confidence) suggests ****************** If you want to allow system to run with NIS Then you must tell SELinux about this by enabling the 'nis_enabled' boolean. You can read 'None' man page for more details. Do setsebool -P nis_enabled 1 ***** Plugin catchall (1.04 confidence) suggests ************************** If you believe that plugin-container should be allowed name_bind access on the udp_socket 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 plugin-containe /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c 0.c1023 Target Context system_u:object_r:unreserved_port_t:s0 Target Objects [ udp_socket ] Source plugin-containe Source Path /usr/lib64/firefox/plugin-container Port 13030 Host (removed) Source RPM Packages firefox-30.0-4.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-166.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.14.7-200.fc20.x86_64 #1 SMP Wed Jun 11 22:38:05 UTC 2014 x86_64 x86_64 Alert Count 22269 First Seen 2014-05-29 20:04:23 CEST Last Seen 2014-06-16 08:23:14 CEST Local ID 71f04232-f04d-4b27-9022-a7a65234a8a4 Raw Audit Messages type=AVC msg=audit(1402899794.559:1426): avc: denied { name_bind } for pid=4992 comm="plugin-containe" src=13030 scontext=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 tcontext=system_u:object_r:unreserved_port_t:s0 tclass=udp_socket type=SYSCALL msg=audit(1402899794.559:1426): arch=x86_64 syscall=bind success=no exit=EACCES a0=16 a1=7ffe2b6b9190 a2=10 a3=7ffe2c07be40 items=0 ppid=3164 pid=4992 auid=1000 uid=1000 gid=1000 euid=1000 suid=1000 fsuid=1000 egid=1000 sgid=1000 fsgid=1000 tty=(none) ses=2 comm=plugin-containe exe=/usr/lib64/firefox/plugin-container subj=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 key=(null) Hash: plugin-containe,mozilla_plugin_t,unreserved_port_t,udp_socket,name_bind Additional info: reporter: libreport-2.2.2 hashmarkername: setroubleshoot kernel: 3.14.7-200.fc20.x86_64 type: libreport Potential duplicate: bug 970466
