GNU Hurd 0.9, GNU Mach 1.8, GNU MIG 1.8 released.

We're pleased to announce new releases!

GNU Hurd 0.9, NEWS: Version 0.9 (2016-12-18) The 'boot' program can now be run as unprivileged user, allowing any user to create unprivileged Subhurds. An ethernet multiplexer (eth-multiplexer translator) has been merged into this repository. This is a network multiplexer that makes available virtual interfaces, and routes traffic between these and a real ethernet interface. It uses the Berkeley Packet Filter library (libbpf), which has also been merged. The ethernet multiplexer now generates and uses stable pseudo-random ethernet addresses for the virtual interfaces. As usual, bugs have been fixed throughout the code, notably in libpager and ext2fs which now gracefully handles running out of space. Further compatibility fixes have been applied (for compliance to standards such as POSIX).

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: documentation, what is the GNU Hurd.

GNU Mach 1.8, NEWS: Version 1.8 (2016-12-18) The memory management system was extensively reworked. A new type for physical addresses is now used where appropriate, and the system can make use of the high memory segment. Many paging issues have been addressed, and as a result the system handles low memory situations more gracefully now. The virtual memory system now uses a red-black tree for allocations, and as a result it now supports tasks with tens of thousands of mappings. Debugging and error reporting has been improved. Among other things the VM maps are now augmented with names that are used in error messages, panics and assertions point to their locations, the lock debugging mechanism has been fixed, and the kernel debugger can now inspect stack traces reaching into the machine-dependent bits implemented in assembler. As usual, bugs have been fixed throughout the code, including minor issues with the gsync synchronization mechanism which is now used for the internal locks in the GNU C Library (glibc). The deprecated external memory management interface has been removed. The partial ACPI support has been removed.

The microkernel 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.

GNU MIG 1.8, NEWS: Version 1.8 (2016-12-18) A spurious warning in the generated code has been fixed.

This tool translates Remote Procedure Call (RPC) definition files to C code, and is required to compile any packages that are receiving or invoking RPCs, such as GNU Mach, GNU Hurd, and the GNU C Library (glibc) when compiled for the Hurd.
