libalias: Remove unused function LibAliasCheckNewLink

2021-06-07T05:51:57Z

The functionality to detect a newly created link after processing a single packet is decoupled from the packet processing. Every new packet is processed asynchronously and will reset the indicator, hence the function is unusable. I made a Google search for third party code, which uses the function, and failed to find one. That's why the function should be removed: It unusable and unused. A much simplified API/ABI will remain in anything below 14.

libalias: Fix -Wcast-align compiler warnings

2021-05-30T14:31:38Z

This fixes -Wcast-align warnings caused by the underaligned `struct ip`. This also silences them in the public functions by changing the function signature from char * to void *. This is source and binary compatible and avoids the -Wcast-align warning. Reviewed By: ae, gbe (manpages) Differential Revision: https://reviews.freebsd.org/D27882

MFC r357092,357787: Add support for RFC 6598/Carrier Grade NAT subnets

2020-04-07T16:27:58Z

to libalias and ipfw. In libalias, a new flag PKT_ALIAS_UNREGISTERED_RFC6598 is added. This is like PKT_ALIAS_UNREGISTERED_ONLY, but also is RFC 6598 aware. Also, we add a new NAT option to ipfw called unreg_cgn, which is like unreg_only, but also is RFC 6598-aware. The reason for the new flags/options is to avoid breaking existing networks, especially those which rely on RFC 6598 as an external address.
