Brings the tarball upgrade restart, release-candidate Debian versions, the rekey-disable deprecation note, the interop harness change, and the Ethernet socket leak, TCP address fallback and gateway NAT retry fixes up from maint. Resolutions: - io_linux.rs: keep master's ENODEV/ENXIO absence branch in the bind failure arm, without its manual close, since the OwnedFd guard now closes the socket on every error return. - The socket leak test runs without #[ignore] under the FIPS_TEST_PRIVILEGED convention, so the privileged CI leg exercises it, and accepts master's InterfaceUnavailable for a missing interface. - tcp/mod.rs: master's connect signature with maint's multi-address resolution; maint's tests, less a helper master no longer uses. - CHANGELOG: maint's entries added under master's areas, with the socket leak entry reworded for master, which has no beacon socket reopen.
FIPS Documentation
FIPS (Free Internetworking Peering System) is a self-organizing encrypted mesh network built on Nostr identities, capable of operating over arbitrary transports — local networks, the public internet, Tor, Bluetooth, or point-to-point links — without central infrastructure.
With FIPS, your machine becomes a node in the mesh with a self-generated cryptographic identity. There are two ways to deploy it.
As an overlay on top of existing IP networks, FIPS lets your node reach any other FIPS node wherever it sits — behind a NAT, on a different ISP, on a phone over cellular, on a laptop with only Bluetooth in range, or behind a Tor onion. The mesh forwards IPv6 traffic transparently and end-to-end encrypted, with no central VPN concentrator or coordinating server.
From the ground up over raw Ethernet, WiFi, or Bluetooth, FIPS provides a complete permissionless network without any pre-existing IP infrastructure, ISP, or DNS. Any node that joins the link gets routable IPv6 addresses, peer discovery, and a path to every other node automatically.
Either way, existing networking software runs over it unchanged: SSH, HTTP servers, file transfer, anything IPv6-native works the same way it would on a local network.
