feat: add support for systemd listener activation sockets

mirror of https://github.com/hacdias/webdav.git synced 2026-09-22 03:20:41 +08:00

To support starting a network service on demand and to
support a "least privilege-approach" with regards to the
permission a network service process needs to have, systemd
supports opening a network socket on behalf of the service
and passing it as an open file descriptor.

The service gets notified about open file descriptors for
this purpose as well as metadata such as named listeners
via environment variables.

This patch adds support for prefixing the listen address
passed with --address with "sd-listen-fd:" to access these
file descriptors, taking either a listener name passed using
the `LISTEN_FDNAMES` environment variable or `LISTEN_FD_$n`
for unnamed file descriptiors where `n` is the id of the
descriptor starting at 3 (LISTEN_FD_3).

See sd_listen_fds(3)
