certs

• Upstream: Mozilla, via https://github.com/bagder/ca-bundle
• Version: git (b2f7415648411b6fd7c298c6c92d6552f0165f60, 2021)

• License: MIT

Files extracted from upstream source:

• all .cpp, .h, and .txt files in ConvectionKernels/

enet

• Upstream: http://enet.bespin.org
• Version: 1.3.17 (e0e7045b7e056b454b5093cb34df49dc4cee0bee, 2020)
• License: MIT

Files extracted from upstream source:

• all .c files in the main directory (except unix.c win32.c)
• the include/enet/ folder as enet/ (except unix.h win32.h)

Important: enet.h, host.c, protocol.c have been slightly modified to be usable by Godot's socket implementation and allow IPv6 and DTLS. Apply the patches in the patches/ folder when syncing on newer upstream commits.

Three files (godot.cpp, enet/godot.h, enet/godot_ext.h) have been added to provide enet socket implementation using Godot classes.

It is still possible to build against a system wide ENet but doing so will limit its functionality to IPv4 only.
