Description Adam Tkac 2011-03-18 10:29:04 UTC
Description of problem:
BIND has a feature to export server statistics through HTTP. However this feature is currently unusable because SELinux denies BIND to bind(2) port 80.

Version-Release number of selected component (if applicable):
# rpm -q selinux-policy-targeted
selinux-policy-targeted-3.9.16-4.fc16.noarch

How reproducible:
always
  
Actual results:
bind(2) is denied:

type=AVC msg=audit(1300449619.385:15): avc:  denied  { name_bind } for  pid=1186 comm="named" src=80 scontext=system_u:system_r:named_t:s0 tcontext=system_u:object_r:http_port_t:s0 tclass=tcp_socket
type=SYSCALL msg=audit(1300449619.385:15): arch=c000003e syscall=49 success=yes exit=0 a0=14 a1=7ff1de4d7600 a2=10 a3=7ff1de4d7210 items=0 ppid=1183 pid=1186 auid=4294967295 uid=25 gid=25 euid=25 suid=25 fsuid=25 egid=25 sgid=25 fsgid=25 tty=(none) ses=4294967295 comm="named" exe="/usr/sbin/named" subj=system_u:system_r:named_t:s0 key=(null)

Expected results:
successful bind(2)

Let me know if you need more information.

Oops, set wrong component. Changing to selinux-policy-targeted.

Comment 2 Miroslav Grepl 2011-03-18 11:15:07 UTC
Should we allow it by default?

Comment 3 Adam Tkac 2011-03-18 11:23:38 UTC

> Should we allow it by default?

If you would like to add new selinux boolean then disable it by default. Not sure if there is another way how to disable enforcing of this rule by default.

Comment 4 Daniel Walsh 2011-03-18 14:06:53 UTC
Should be a boolean.

named_bind_http_port

Off by default.

Sounds fine for me.

Comment 6 Miroslav Grepl 2011-04-04 16:55:01 UTC
Should be fixed in the latest f15 policy.
