SELinux

Web

Autoriser un dossier à être lu par le serveur Web.

chcon -Rt httpd_sys_content_t /path/to/www

Conteneurs

Autoriser un conteneur à accéder à un dossier mappé sur l'hôte (flag Z).

podman run --rm -v /path/to/volume:/data:Z debian

Creer une policy custom (podman):

Extraire les settings du conteneur et run udica dessus :

podman inspect <id/nom du pod> > conteneur.json

udica -j conteneur.json mon_conteneur

Editer le fichier .cil créé, et ajouter/modifier selon ce que vous voulez autoriser

Exemple pour qbittorrent :

(block qbittorrent
    (blockinherit container)
    (blockinherit restricted_net_container)
    (allow process process ( capability ( chown dac_override fowner fsetid kill net_bind_service setfcap setgid setpcap setuid sys_chroot )))
    
    # Autorise a se bind et a contacter tous les ports
    (allow process port_type ( tcp_socket (  name_bind name_connect )))
    (allow process port_type ( udp_socket (  name_bind )))

    # Autorise a acceder aux fichier avec le contexte httpd_user_ra_content_t
    (allow process httpd_user_ra_content_t ( dir ( add_name create getattr ioctl lock open read remove_name rmdir search setattr write )))
    (allow process httpd_user_ra_content_t ( file ( append create getattr ioctl lock map open read rename setattr link unlink write )))
    (allow process httpd_user_ra_content_t ( fifo_file ( getattr read write append ioctl lock open )))
    (allow process httpd_user_ra_content_t ( sock_file ( append getattr open read write link create setattr unlink execute rename )))

    (allow process default_t ( dir ( add_name create getattr ioctl lock open read remove_name rmdir search setattr write )))
    (allow process default_t ( file ( append create getattr ioctl lock map open read rename setattr unlink write )))
    (allow process default_t ( fifo_file ( getattr read write append ioctl lock open )))
    (allow process default_t ( sock_file ( append getattr open read write )))
    (allow process var_t ( dir ( add_name create getattr ioctl lock open read remove_name rmdir search setattr write )))
    (allow process var_t ( file ( append create getattr ioctl lock map open read rename setattr unlink write )))
    (allow process var_t ( fifo_file ( getattr read write append ioctl lock open )))
    (allow process var_t ( sock_file ( append getattr open read write )))
)
