Hi,
the IP_FREEBIND option allows binding to an IP address that is nonlocal
or does not (yet) exist.
This is useful, for example, for daemons integration with systemd [1].
When daemon wants to bind to particular IP address during system start,
there is no way how to determine that the network interface is really
configured and the IP address is available.
Patch in the PR58725 adds support for IP_FREEBIND to APR.
As I said in the bug, I'm not sure if we need to change also win32/os2
implementation of apr_socket_opt_set - more opinions are welcome.
Could you please review that patch and write me your thoughts?
