The alert above tells you how you can fix this problem? Why did you think this is a bug? I started to apply the suggested fix... grep /var/www/cgi-bin/cachemgr.cgi /var/log/audit/audit.log | audit2allow -M mypol generated an error, which I reported in the bug report - see comment #1 above. The contents of mypol: $ cat /data/home/gavin/mypol.te module mypol 1.0; $ So I attempted to carry out the suggested remedy, and it appeared to fail. So I still think there is a bug - or perhaps, I have misunderstood something that is 'obvious'. After further looking at this bug and others you reported. I realize this is a labeling issue. I am looking into to fixing the alert message to fix that problem, also. *** This bug has been marked as a duplicate of bug 666103 *** |
# grep /var/www/cgi-bin/cachemgr.cgi /var/log/audit/audit.log | audit2allow -M mypol compilation failed: mypol.te:6:ERROR 'syntax error' at token '' on line 6: /usr/bin/checkmodule: error(s) encountered while parsing configuration /usr/bin/checkmodule: loading policy configuration from mypol.te //////////////////////////// SELinux is preventing /var/www/cgi-bin/cachemgr.cgi from 'name_connect' accesses on the tcp_socket port 3128. ***** Plugin catchall_boolean (89.3 confidence) suggests ******************* If you want to allow HTTPD scripts and modules to connect to the network using any TCP port. Then you must tell SELinux about this by enabling the 'httpd_can_network_connect' boolean. Do setsebool -P httpd_can_network_connect 1 ***** Plugin catchall (11.6 confidence) suggests *************************** If you believe that cachemgr.cgi should be allowed name_connect access on the port 3128 tcp_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 /var/www/cgi-bin/cachemgr.cgi /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:httpd_sys_script_t:s0 Target Context system_u:object_r:squid_port_t:s0 Target Objects port 3128 [ tcp_socket ] Source cachemgr.cgi Source Path /var/www/cgi-bin/cachemgr.cgi Port 3128 Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.9.7-18.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 2.6.35.10-72.fc14.x86_64 #1 SMP Mon Dec 20 21:14:22 UTC 2010 x86_64 x86_64 Alert Count 27 First Seen Thu 23 Dec 2010 08:10:29 AM NZDT Last Seen Sun 26 Dec 2010 01:00:53 PM NZDT Local ID d77d0840-8316-4d43-a125-d222db58e1ce Raw Audit Messages type=AVC msg=audit(1293321653.191:49154): avc: denied { name_connect } for pid=21542 comm="cachemgr.cgi" dest=3128 scontext=system_u:system_r:httpd_sys_script_t:s0 tcontext=system_u:object_r:squid_port_t:s0 tclass=tcp_socket cachemgr.cgi,httpd_sys_script_t,squid_port_t,tcp_socket,name_connect type=SYSCALL msg=audit(1293321653.191:49154): arch=x86_64 syscall=connect success=yes exit=0 a0=3 a1=7f448c1d0770 a2=10 a3=7fffe5be2dd0 items=0 ppid=9219 pid=21542 auid=4294967295 uid=48 gid=48 euid=48 suid=48 fsuid=48 egid=48 sgid=48 fsgid=48 tty=(none) ses=4294967295 comm=cachemgr.cgi exe=/var/www/cgi-bin/cachemgr.cgi subj=system_u:system_r:httpd_sys_script_t:s0 key=(null) cachemgr.cgi,httpd_sys_script_t,squid_port_t,tcp_socket,name_connect #============= httpd_sys_script_t ============== #!!!!
