DragonFly BSD

Code Bounties

Explanation

A code bounty is a certain financial stimulant to encourage someone to put his or her effort into a project. A code bounty in the DragonFlyBSD project needs to adhere to a set of rules defined hereunder, though these are only preliminary and subject to change. One could for example imagine developers accepting sponsorship on a wholly different basis, or non-financial rewards for completing a bounty project, like free hardware (we love that!).

Port tarfs from FreeBSD 14

Description

FreeBSD 14 got tarfs which allows to mount a POSIX tar file, possibly zstd compressed. The task is to port this over to DragonFly.

One possible use case of tarfs would be for the installer ISO image where various parts of the system could be mounted from a tar.xz file leading to a partially "compressed" ISO image.

HAMMER2 offline deduplication

Description

HAMMER2 has online deduplication which works well for long-running servers. But if the system is rebooted, the deduplication caches are emptied and newly written data will possibly be stored duplicated.

HAMMER2 offline deduplication would fill the gap, allowing to deduplicate existing file systems which have already gained duplicate data.

Ideally, a framework is developed that can be reused for similar tasks, e.g.:

Bring in support for USB webcams

Description

Bring in uvideo from NetBSD or OpenBSD, and the dependent video driver. If you think that webcam support in FreeBSD is superior, feels free to bring in cuse etc.

Final result should be that USB webcams are usable from chrome or firefox for the purpose of video conferencing (e.g. via jitsi.org). Personally I only need support for low-quality webcams, no need for 4k :).

Port uhidd HID daemon from FreeBSD

Description

uhidd is a userland driver/daemon for USB HID devices like mouse, keyboard etc. It is based on libusb20 and currently only works for FreeBSD 8.x and above.

The uhidd driver would allow USB gaming controllers and joysticks to be used on DragonFly BSD. uhidd also provide support for multimedia keys found on USB keyboards.

Bluetooth-Support

Full Rust libc FFI binding support

Description

Technical details

There has intermittently been some support on this and builds and tests have gone through periods of passing and failing, but a comprehensive buildout of full support of all features would make more advanced Rust development, especially as a viable web server backend more possible.

HAMMER compression

Description

(shamelessly copied from gsoc2010 projects page)

NOTE: HAMMER2 has replaced HAMMER to be the default filesystem on DragonFly and is under active development and maintenance. HAMMER2 also has compression support.

Technical details

(shamelessly copied from gsoc2010 projects page)

Doing compression would require flagging the data record as being compressed and also require double-buffering since the buffer cache buffer associated with the uncompressed data might have holes in it and otherwise referenced by user programs and cannot serve as a buffer for in-place compression or decompression.

The direct read / direct write mechanic would almost certainly have to be disabled for compressed buffers and the small-data zone would probably have to be used (the large-data zone is designed only for use with 16K or 64K buffers).

In-kernel WireGuard port

Description

WireGuard is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. Initially released for the Linux kernel, it is now cross-platform (Windows, macOS, BSD, iOS, Android) and widely deployable. (copied from WireGuard official website)

We already have the userland implementation in Golang in DPorts (i.e., wireguard-go). It would be better to also gain the in-kernel implementation, like OpenBSD and FreeBSD already did.

Technical details

NOTE: The initial port by FreeBSD/Netgate was buggy, so need to investigate before using that code. See: Buffer overruns, license violations, and bad code: FreeBSD 13's close call

The re-port of WireGuard to FreeBSD: [ANNOUNCE] WireGuard for FreeBSD in development for 13.y – and a note of how we got here.

The Author (Jason A. Donenfeld) also said "the crypto needed to be re-accelerated", as detailed in if_wg simd chapoly needs some love.

NOTE: NetBSD has a separate from-sratch implementation wg(4). The code looks quite clean and nice. So it maybe a good idea to port the NetBSD version.

See also the dispute between WireGuard's author and NetBSD developers: "wireguard" implementation improperly merged and needs revert

Port valgrind to DragonFlyBSD [TAKEN 2021-03-30]

Description

(shamelessly copied from gsoc2010 projects page)

Valgrind is a very useful tool on a system like DragonFly that's under heavy development. Ideally, we would want the port to be usable with vkernel processes, thus enabling complex checking of the core kernel code.

Technical details

Not yet written.

Main goals

(shamelessly copied from gsoc2010 projects page)

The goal of this project is to port valgrind (3.5.0+) to the DragonFlyBSD platform so that at least the memcheck tool runs sufficiently well to be useful. Also an update for the pkgsrc package (devel/valgrind) should be made.
