Allow journald to read the kernel ring buffer and to use /dev/kmsg
audit.log shows that journald needs to read the kernel read buffer:
avc: denied { syslog_read } for pid=147 comm="systemd-journal" scontext=system_u:system_r:syslogd_t tcontext=system_u:system_r:kernel_t tclass=system permissive=1
Moreover journald uses RW access to /dev/kmsg, according to its code:
http://cgit.freedesktop.org/systemd/systemd/tree/src/journal/journald-kmsg.c?id=v215#n394
