Description Konstantin Ryabitsev 2004-03-29 16:55:02 EST
Description of problem:
SELinux enforcement disables remote server logging for syslog,
creating the following entries in messages:

Mar 29 13:25:56 hagrid kernel: audit(1080584756.667:0): avc:  denied 
{ name_bind } for  pid=3162 exe=/sbin/syslogd src=832
scontext=root:system_r:syslogd_t tcontext=system_u:object_r:port_t

It looks like the default policy should allow this, as remote logging
is used quite often.

Comment 1 Konstantin Ryabitsev 2004-03-30 15:36:18 EST
Adding the following to
/etc/security/selinux/src/policy/domains/program/syslogd.te fixes the
issue and allows both sending logs to remote server and accepting
remote logs.

# Allow name_bind for remote logging
allow syslogd_t port_t:{ tcp_socket udp_socket } name_bind;

tcp_socket can be used by syslog_ng, afair.
Comment 2 Daniel Walsh 2004-05-06 13:50:15 EDT
Fixed in policy-1.11.3-2.src.rpm
