He writes that + +> ``` ...there is now a real port of GNU Mach to AArch64, using these headers as +> its actual API/ABI. We got the Mach port to run glibc, several Hurd servers, +> and simple Unix programs, including things like fork/exec and signal delivery +> & handling working, which exercises these architecture-specific definitions +> (thread state & exceptions). We have also managed to do some testing on real +> hardware; although not everything is working yet, we have seen thread state +> manipulation & Mach handling an unaligned SP fault work as expected. ``` + +His email also mentions that the GCC patches that enable GCC to compile GNU/Hurd +programs on AArch64 have been merged! This apparently will make it easier to +merge his AArch64 specific glibc patches. + +He also added new tests to check that [threads handle signals +well](https://lists.gnu.org/archive/html/bug-hurd/2024-04/msg00031.html), and he +also fixed a [use-after-free in +vm_map_pageable_scan()](https://lists.gnu.org/archive/html/bug-hurd/2024-04/msg00005.html). +He also added support to [copy a send once +right](https://lists.gnu.org/archive/html/bug-hurd/2024-04/msg00001.html) to +Mach and MIG, and he hosted a [lengthy Hurd code +jam](https://www.youtube.com/watch?v=lQ7bWzsL7Ps) (apologies for the poor audio +quality). + +Some time ago, Sergey also wrote the +[terrible-mdns-responder](https://darnassus.sceen.net/~hurd-web/hurd/terrible-mdns-responder/), +and if you would like to be able to type in `ssh HOSTNAME.local` and connect to +a locally running Hurd, then you may want to try it! + +Flávio Cruz fixed some issues with the Hurd compiling +[on](https://lists.gnu.org/archive/html/bug-hurd/2024-06/msg00023.html) +[GCC](https://lists.gnu.org/archive/html/bug-hurd/2024-06/msg00028.html) +[14](https://lists.gnu.org/archive/html/bug-hurd/2024-06/msg00024.html). + +Luca Dariz fixed message sizes, where the size was [not set by +userspace](https://lists.gnu.org/archive/html/bug-hurd/2024-06/msg00015.html), +and he added another test to [check message sizes on various code +paths](https://lists.gnu.org/archive/html/bug-hurd/2024-06/msg00014.html). + +Debian GNU/Hurd now offers an experimental [SMP GNU Mach +kernel](https://lists.debian.org/debian-hurd/2024/04/msg00006.html) (32-bit +only) and the [official rustc +compiler](https://lists.debian.org/debian-hurd/2024/05/msg00016.html)! Now that +we have ported rustc to Debian GNU/Hurd, we can compile important packages like +librsvg. Debian GNU/Hurd now can compile [71% of the packages from the Debian +archive](https://logs.guix.gnu.org/hurd/2024-06-25.log). + +Now for something trivial but fun! I updated the guide on the Hurd wiki that +shows how one can run their own [personal ext2fs +translator](https://darnassus.sceen.net/~hurd-web/hurd/translator/ext2fs/). + +You could go crazy even! Why not make something like this: + + ~/silly <--> silly.fs + | \ + | \ + | \ + | \ + | \ + \|/ \/ + silly1 <-> silly1.fs + ... + + /hurd/joshua/silly/silly1/silly2/silly3/silly4 + +Each sillyN is another ext2fs filesystem! Make sure that as N gets bigger +sillyN.fs gets smaller. Let us know in the #hurd irc channel how "silly" +you are. :) + +The current record is `~/silly1/silly2` where each `sillyN` is a different +ext2fs. Does anyone want to volunteer to beat the current record? + +So if you want to test if your favorite packages work on the Hurd and +contribute towards making the full GNU system usable for a wider range +of people, please [[check the contributing page|contributing]]. + +--- + +The **GNU Hurd** is the GNU project's replacement for the Unix kernel. It is a +collection of servers that run on the Mach microkernel to implement file +systems, network protocols, file access control, and other features that are +implemented by the Unix kernel or similar kernels (such as Linux). [[More +detailed|hurd/documentation]]. + +**GNU Mach** is the microkernel upon which a GNU Hurd system is based. It +provides an Inter Process Communication (IPC) mechanism that the Hurd uses to +define interfaces for implementing in a distributed multi-server fashion the +services a traditional operating system kernel provides.
