Crate arcbox_helper 

arcbox-helper shared types and client.

This library defines the tarpc service interface for the privileged helper daemon and provides a high-level client::Client for consumers (arcbox-core, arcbox-daemon).

Modules

client

High-level client for communicating with the arcbox-helper daemon.

validate

Input validation for setuid defense-in-depth.

Structs

HelperServiceClient

The client stub that makes RPC calls to the server. All request methods return Futures.

ServeHelperService

A serving function to use with ::tarpc::server::InFlightRequest::execute.

Enums

HelperServiceRequest

The request sent over the wire from the client to the server.

HelperServiceResponse

The response sent over the wire from the server to the client.

Constants

HELPER_SOCKET

Unix socket path where the helper daemon listens.

HELPER_SOCKET_ENV

Override the socket path for development/testing.

HOSTS_ALIAS_LINE

The one /etc/hosts line the helper manages. The trailing comment tags the line so uninstall removes exactly what was installed.

HOSTS_ALIAS_NAME

Host name the managed /etc/hosts alias resolves to loopback.

Traits

HelperService

The tarpc service definition for privileged host mutations.

HelperServiceStub

The stub trait for service HelperService.

Functions

hosts_alias_installed

True when hosts_content (the text of /etc/hosts) carries the managed alias line. Shared by the helper mutation, the daemon’s self-setup check, and the NFS mount’s source selection.

socket_path

Returns the effective socket path, checking the env override first.
