A few additional rules are needed when pasta is started by Podman in particular cases: - with podman-build or Buildah, pasta needs to access the target namespace reference using a procfs namespace link entry, instead of the usual directory under /run or /var/run. For that, we have a rule enabling access to container_t:lnk_file. On some systems, though, the class is 'dir' instead of 'lnk_file'. I don't have a concrete way to reproduce this or a full explanation, but in any case, an additional rule for that is obviously harmless: allow pasta_t to open, read, and search a container_t:dir - with custom networks, pasta needs to write PID files to a location indicated by Podman. If the PID file already exists, the existing permissions aren't sufficient: we also need a 'read' rule. Add that, for 'dir' and 'file' objects labeled as either container_var_run_t or ifconfig_var_run_t (this depends on the installed Podman and container-selinux versions) Signed-off-by: Stefano Brivio --- contrib/selinux/pasta.te | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/contrib/selinux/pasta.te b/contrib/selinux/pasta.te index ff74dd7..9394f97 100644 --- a/contrib/selinux/pasta.te +++ b/contrib/selinux/pasta.te @@ -175,6 +175,7 @@ allow pasta_t container_runtime_t:fifo_file { getattr write }; allow pasta_t container_runtime_t:file read; allow pasta_t container_runtime_t:lnk_file read; allow pasta_t container_t:lnk_file read; +allow pasta_t container_t:dir { open read search }; allow pasta_t pasta_port_t:tcp_socket { name_bind name_connect }; allow pasta_t pasta_port_t:udp_socket { name_bind }; allow pasta_t http_port_t:tcp_socket { name_bind name_connect }; @@ -249,10 +250,10 @@ type_transition container_runtime_t user_tmp_t : dir ifconfig_var_run_t "netns"; type_transition container_runtime_t container_var_run_t : dir ifconfig_var_run_t "netns"; type_transition container_runtime_t user_tmp_t : dir ifconfig_var_run_t "rootless-netns"; type_transition container_runtime_t container_var_run_t : dir ifconfig_var_run_t "rootless-netns"; -allow pasta_t container_var_run_t:dir { add_name open rmdir write }; -allow pasta_t ifconfig_var_run_t:dir { add_name open rmdir write }; -allow pasta_t container_var_run_t:file { create open write }; -allow pasta_t ifconfig_var_run_t:file { create open write }; +allow pasta_t container_var_run_t:dir { add_name open read rmdir write }; +allow pasta_t ifconfig_var_run_t:dir { add_name open read rmdir write }; +allow pasta_t container_var_run_t:file { create open read write }; +allow pasta_t ifconfig_var_run_t:file { create open read write }; allow pasta_t container_var_run_t:sock_file { getattr create open read write }; allow pasta_t ifconfig_var_run_t:sock_file { getattr create open read write }; allow systemd_user_runtimedir_t ifconfig_var_run_t:dir rmdir; -- 2.43.0
