Description Francisco de la Peña 2019-09-30 01:33:58 UTC
Description of problem:
SELinux is preventing bwrap from 'nlmsg_write' accesses on the netlink_route_socket Desconocido.

*****  Plugin catchall (100. confidence) suggests   **************************

Si cree que de manera predeterminada se debería permitir a bwrap el acceso nlmsg_write sobre  Desconocido netlink_route_socket.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso temporalmente ejecutando:
# ausearch -c 'bwrap' --raw | audit2allow -M mi-bwrap
# semodule -X 300 -i mi-bwrap.pp
