I would probably file a bugreport to fedora bugzilla for nagios, and ask
the packager to put the non-log files in more appropriate places
(/var/lib/nagios or /run/nagios maybe?), i would also cc. the fedora
selinux-policy maintainer (mgrepl) so that he can add selinux policy to
support the proper solution if needed.
Type nagios_var_lib_t seems appropriate:
allow nagios_t nagios_var_lib_t : file { ioctl read write create
getattr setattr lock append unlink link rename open } ;
allow nagios_t nagios_var_lib_t : dir { ioctl read write getattr lock
add_name remove_name search open } ;
allow nagios_t nagios_var_run_t : file { ioctl read write create
getattr setattr lock append unlink link rename open } ;
allow nagios_t nagios_var_run_t : dir { ioctl read write getattr lock
add_name remove_name search open } ;
allow nagios_t nagios_var_lib_t : fifo_file { ioctl read write create
getattr setattr lock append unlink link rename open } ;
# semanage fcontext -l | grep nagios_var_lib_t
/usr/lib/pnp4nagios(/.*)? all files
system_u:object_r:nagios_var_lib_t:s0
