Could you please re-test it with permissive mode and attach raw AVC msgs? Thank you. AVC messages:

and corresponding /var/log/firewalld (not exactly but the same program touching almost the same files during analogous action - network interface status change):

Description of problem: SELinux is preventing /usr/bin/python2.7 from 'write' accesses on the directory /etc/sysconfig/network-scripts. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that python2.7 should be allowed write access on the network-scripts directory 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: # ausearch -c 'firewalld' --raw | audit2allow -M my-firewalld # semodule -i my-firewalld.pp Additional Information: Source Context system_u:system_r:firewalld_t:s0 Target Context system_u:object_r:net_conf_t:s0 Target Objects /etc/sysconfig/network-scripts [ dir ] Source firewalld Source Path /usr/bin/python2.7 Port <Unknown> Host (removed) Source RPM Packages python-2.7.5-44.el7.x86_64 Target RPM Packages initscripts-9.49.30-1.el7_2.2.x86_64 Policy RPM selinux-policy-3.13.1-78.el7.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.10.0-429.el7.BZ1332712_usbv4.6.x86_64 #1 SMP Thu Jun 9 10:21:02 EDT 2016 x86_64 x86_64 Alert Count 2 First Seen 2016-06-13 17:39:03 CEST Last Seen 2016-06-14 14:58:45 CEST Local ID cd43b8f1-ba32-40eb-aa26-250a62519c25 Raw Audit Messages type=AVC msg=audit(1465909125.934:834): avc: denied { write } for pid=1345 comm="firewalld" name="network-scripts" dev="dm-4" ino=12703240 scontext=system_u:system_r:firewalld_t:s0 tcontext=system_u:object_r:net_conf_t:s0 tclass=dir type=SYSCALL msg=audit(1465909125.934:834): arch=x86_64 syscall=open success=no exit=EACCES a0=34e8030 a1=200c2 a2=180 a3=4 items=0 ppid=1 pid=1345 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=firewalld exe=/usr/bin/python2.7 subj=system_u:system_r:firewalld_t:s0 key=(null) Hash: firewalld,firewalld_t,net_conf_t,dir,write Version-Release number of selected component: selinux-policy-3.13.1-78.el7.noarch Additional info: reporter: libreport-2.1.11.1 hashmarkername: setroubleshoot kernel: 3.10.0-429.el7.BZ1332712_usbv4.6.x86_64 reproducible: Not sure how to reproduce the problem type: libreport
