SELinux module that allows freshclam proxy connection
I'm sorry, the version of components are from another computer with Fedora 17. The actual versions are: selinux-policy-targeted-3.10.0-89.fc16.noarch clamav-update-0.97.3-1600.fc16.i686 Fixed. Hello there, I have the very same problem with clamav-0.97.5-1.el6.x86_64 in RHEL 6.3 but in my case I setted the proxy parameters in /etc/freshclam.conf using the HTTPProxy* directives.
I got the following entries in audit.log:
type=AVC msg=audit(1349251647.435:43404): avc: denied { name_connect } for pid=6865 comm="freshclam" dest=8080 scontext=system_u:system_r:freshclam_t:s0-s0:c0.c1023 tcontext=system_u:object_r:http_cache_port_t:s0 tclass=tcp_socket
type=SYSCALL msg=audit(1349251647.435:43404): arch=c000003e syscall=42 success=no exit=-13 a0=5 a1=17253f0 a2=10 a3=0 items=0 ppid=6863 pid=6865 auid=0 uid=496 gid=492 euid=496 suid=496 fsuid=496 egid=492 sgid=492 fsgid=492 tty=(none) ses=2999 comm="freshclam" exe="/usr/bin/freshclam" subj=system_u:system_r:freshclam_t:s0-s0:c0.c1023 key=(null)
And using the audit2allow tool it generated the following policy:
module freshclam-mypol 1.0;
require {
type freshclam_t;
type http_cache_port_t;
class tcp_socket name_connect;
}
#============= freshclam_t ==============
allow freshclam_t http_cache_port_t:tcp_socket name_connect;
I still have to wait until tomorrow to confirm if this actually solves the problem.
The affected packages are:
selinux-policy-3.7.19-154.el6.noarch
selinux-policy-targeted-3.7.19-154.el6.noarch
libselinux-2.0.94-5.3.el6.x86_64
I really hope this gets fixed in RHEL.
Thanks.
