The system-config-samba backend mechanism (/usr/share/system-config-samba/system-config-samba-mechanism.py) checks whether both /bin/systemctl and /bin/systemd are executable -- access(..., X_OK) -- to determine if it should use systemd or SysV methods to handle system services. I figure this causes the AVC denial -- it definitely doesn't execute the program. It must be allowed to check for this in order to work right, changing component accordingly. NB: the AVC denial only happens if the mechanism is started via dbus service activation. If I start it manually as root, I don't get it. Yeap, as you say, this is access check syscall=access Fixed in selinux-policy-3.10.0-138.fc17.noarch selinux-policy-3.10.0-142.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/selinux-policy-3.10.0-142.fc17 Package selinux-policy-3.10.0-142.fc17: * should fix your issue, * was pushed to the Fedora 17 testing repository, * should be available at your local mirror within two days.

Get SE Linux errors, 3 every time I run it. This happens before I can authenticate as root. (I sometimes get other errors as well). SELinux is preventing /usr/bin/python2.7 from execute access on the file /usr/lib/systemd/systemd. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that python2.7 should be allowed execute access on the systemd 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 system-config-s /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:sambagui_t:s0-s0:c0.c1023 Target Context system_u:object_r:init_exec_t:s0 Target Objects /usr/lib/systemd/systemd [ file ] Source system-config-s Source Path /usr/bin/python2.7 Port <Unknown> Host apollo Source RPM Packages python-2.7.3-6.fc17.x86_64 Target RPM Packages systemd-44-17.fc17.x86_64 Policy RPM selinux-policy-3.10.0-134.fc17.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name apollo Platform Linux apollo 3.4.4-5.fc17.x86_64 #1 SMP Thu Jul 5 20:20:59 UTC 2012 x86_64 x86_64 Alert Count 1 First Seen Wed 11 Jul 2012 12:03:38 AM PDT Last Seen Wed 11 Jul 2012 12:03:38 AM PDT Local ID 052ec02c-b32c-4ae2-91cf-71c37d4864dc Raw Audit Messages type=AVC msg=audit(1341990218.160:4937): avc: denied { execute } for pid=7131 comm="system-config-s" name="systemd" dev="dm-1" ino=2097772 scontext=system_u:system_r:sambagui_t:s0-s0:c0.c1023 tcontext=system_u:object_r:init_exec_t:s0 tclass=file type=SYSCALL msg=audit(1341990218.160:4937): arch=x86_64 syscall=access success=no exit=EACCES a0=fc69d0 a1=1 a2=3ea73b39c8 a3=20 items=0 ppid=1 pid=7131 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=system-config-s exe=/usr/bin/python2.7 subj=system_u:system_r:sambagui_t:s0-s0:c0.c1023 key=(null) Hash: system-config-s,sambagui_t,init_exec_t,file,execute audit2allowunable to open /sys/fs/selinux/policy: Permission denied audit2allow -Runable to open /sys/fs/selinux/policy: Permission denied
