Description of problem: Default NetworkManager-l2tp configuration prevent users from using xl2tpd and SELinux simultaneously. SELinux is preventing /usr/sbin/xl2tpd from 'getattr' accesses on the file /run/nm-xl2tpd.conf.7319. ***** Plugin restorecon (99.5 confidence) suggests ************************* If you want to fix the label. /run/nm-xl2tpd.conf.7319 default label should be var_run_t. Then you can run restorecon. Do # /sbin/restorecon -v /run/nm-xl2tpd.conf.7319 ***** Plugin catchall (1.49 confidence) suggests *************************** If you believe that xl2tpd should be allowed getattr access on the nm-xl2tpd.conf.7319 file 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 xl2tpd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:l2tpd_t:s0 Target Context system_u:object_r:NetworkManager_var_run_t:s0 Target Objects /run/nm-xl2tpd.conf.7319 [ file ] Source xl2tpd Source Path /usr/sbin/xl2tpd Port <Unknown> Host (removed) Source RPM Packages xl2tpd-1.3.1-9.fc17.x86_64 Target RPM Packages Policy RPM selinux-policy-3.10.0-169.fc17.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 3.8.13-100.fc17.x86_64 #1 SMP Mon May 13 13:36:17 UTC 2013 x86_64 x86_64 Alert Count 2 First Seen 2013-06-01 18:01:51 JST Last Seen 2013-06-01 18:08:00 JST Local ID 6c7ad347-5f31-44d9-a49c-0f27aee26537 Raw Audit Messages type=AVC msg=audit(1370077680.415:450): avc: denied { getattr } for pid=7321 comm="xl2tpd" path="/run/nm-xl2tpd.conf.7319" dev="tmpfs" ino=84228 scontext=system_u:system_r:l2tpd_t:s0 tcontext=system_u:object_r:NetworkManager_var_run_t:s0 tclass=file type=SYSCALL msg=audit(1370077680.415:450): arch=x86_64 syscall=fstat success=yes exit=0 a0=3 a1=7fff6c084400 a2=7fff6c084400 a3=0 items=0 ppid=7319 pid=7321 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=xl2tpd exe=/usr/sbin/xl2tpd subj=system_u:system_r:l2tpd_t:s0 key=(null) Hash: xl2tpd,l2tpd_t,NetworkManager_var_run_t,file,getattr audit2allow #============= l2tpd_t ============== #!!!!

Added fixes.
selinux-policy-3.10.0-170.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/selinux-policy-3.10.0-170.fc17
Package selinux-policy-3.10.0-170.fc17: * should fix your issue, * was pushed to the Fedora 17 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing selinux-policy-3.10.0-170.fc17' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2013-10302/selinux-policy-3.10.0-170.fc17 then log in and leave karma (feedback).
Tested the testing package and it WFM for xl2tpd. However, as I mentioned in https://admin.fedoraproject.org/updates/FEDORA-2013-10302/selinux-policy-3.10.0-170.fc17, further permissions for NetworkManager_t and pppd_t are needed in order for nm-l2tp to work fine. Following is a result of "# audit2allow -b" which I ran just after booting and starting L2TP VPN (some empty breaks are ommited): #============= NetworkManager_t ============== allow NetworkManager_t l2tp_port_t:udp_socket name_bind; allow NetworkManager_t l2tpd_t:process signal; allow NetworkManager_t l2tpd_t:process sigkill; #============= pppd_t ============== allow pppd_t NetworkManager_var_run_t:file read; So is there any chance to commit them into the current testing package?
Could you please attach AVC msgs for these rules. Thank you.
