fail2ban is a program which watches logs and modifies firewall rules when it finds things like multiple ssh login failures from an address. When it does this, it can send an email to the system administrator. It is common for these emails to include relevant log entries, which it extracts by shelling out: When you have a syslog daemon running, it can just grep /var/log/messages, which works fine. But if you want it to extract those messages from the journal, it needs to call journalctl. This is not the default in Fedora, though it would be nice if it could be. The problem is that fail2ban_t can't call journalctl: time->Thu Mar 14 19:02:19 2019 type=AVC msg=audit(1552608139.605:2851776): avc: denied { getattr } for pid=23673 comm="sh" path="/usr/bin/journalctl" dev="dm-0" ino=4560324 scontext=system_u:system_r:fail2ban_t:s0 tcontext=system_u:object_r:journalctl_exec_t:s0 tclass=file permissive=1 ---- time->Thu Mar 14 19:02:19 2019 type=AVC msg=audit(1552608139.605:2851777): avc: denied { execute } for pid=23673 comm="sh" name="journalctl" dev="dm-0" ino=4560324 scontext=system_u:system_r:fail2ban_t:s0 tcontext=system_u:object_r:journalctl_exec_t:s0 tclass=file permissive=1 ---- time->Thu Mar 14 19:02:19 2019 type=AVC msg=audit(1552608139.606:2851778): avc: denied { read } for pid=23673 comm="sh" name="journalctl" dev="dm-0" ino=4560324 scontext=system_u:system_r:fail2ban_t:s0 tcontext=system_u:object_r:journalctl_exec_t:s0 tclass=file permissive=1 ---- time->Thu Mar 14 19:02:19 2019 type=AVC msg=audit(1552608139.606:2851779): avc: denied { open } for pid=23673 comm="sh" path="/usr/bin/journalctl" dev="dm-0" ino=4560324 scontext=system_u:system_r:fail2ban_t:s0 tcontext=system_u:object_r:journalctl_exec_t:s0 tclass=file permissive=1 ---- time->Thu Mar 14 19:02:19 2019 type=AVC msg=audit(1552608139.606:2851780): avc: denied { execute_no_trans } for pid=23673 comm="sh" path="/usr/bin/journalctl" dev="dm-0" ino=4560324 scontext=system_u:system_r:fail2ban_t:s0 tcontext=system_u:object_r:journalctl_exec_t:s0 tclass=file permissive=1 ---- time->Thu Mar 14 19:02:19 2019 type=AVC msg=audit(1552608139.606:2851781): avc: denied { map } for pid=23673 comm="journalctl" path="/usr/bin/journalctl" dev="dm-0" ino=4560324 scontext=system_u:system_r:fail2ban_t:s0 tcontext=system_u:object_r:journalctl_exec_t:s0 tclass=file permissive=1 ---- time->Thu Mar 14 19:02:19 2019 type=AVC msg=audit(1552608139.627:2851782): avc: denied { sys_resource } for pid=23673 comm="journalctl" capability=24 scontext=system_u:system_r:fail2ban_t:s0 tcontext=system_u:system_r:fail2ban_t:s0 tclass=capability permissive=1 ---- time->Thu Mar 14 19:02:19 2019 type=AVC msg=audit(1552608139.627:2851783): avc: denied { setrlimit } for pid=23673 comm="journalctl" scontext=system_u:system_r:fail2ban_t:s0 tcontext=system_u:system_r:fail2ban_t:s0 tclass=process permissive=1
