FreeBSD src
74ae3f3e33
This is the culmination of about a week of work from three developers to fix a number of functional and security issues. This patch consists of work done by the following folks: - Jason A. Donenfeld <Jason@zx2c4.com> - Matt Dunwoodie <ncon@noconroy.net> - Kyle Evans <kevans@FreeBSD.org> Notable changes include: - Packets are now correctly staged for processing once the handshake has completed, resulting in less packet loss in the interim. - Various race conditions have been resolved, particularly w.r.t. socket and packet lifetime (panics) - Various tests have been added to assure correct functionality and tooling conformance - Many security issues have been addressed - if_wg now maintains jail-friendly semantics: sockets are created in the interface's home vnet so that it can act as the sole network connection for a jail - if_wg no longer fails to remove peer allowed-ips of 0.0.0.0/0 - if_wg now exports via ioctl a format that is future proof and complete. It is additionally supported by the upstream wireguard-tools (which we plan to merge in to base soon) - if_wg now conforms to the WireGuard protocol and is more closely aligned with security auditing guidelines Note that the driver has been rebased away from using iflib. iflib poses a number of challenges for a cloned device trying to operate in a vnet that are non-trivial to solve and adds complexity to the implementation for little gain. The crypto implementation that was previously added to the tree was a super complex integration of what previously appeared in an old out of tree Linux module, which has been reduced to crypto.c containing simple boring reference implementations. This is part of a near-to-mid term goal to work with FreeBSD kernel crypto folks and take advantage of or improve accelerated crypto already offered elsewhere. There's additional test suite effort underway out-of-tree taking advantage of the aforementioned jail-friendly semantics to test a number of real-world topologies, based on netns.sh. Also note that this is still a work in progress; work going further will be much smaller in nature. MFC after: 1 month (maybe) |

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
