GNU Hurd 0.7, GNU Mach 1.6, GNU MIG 1.6 released.

We're pleased to announce new releases!

GNU Hurd 0.7, NEWS: Version 0.7 (2015-10-31) The node cache in ext2fs has been improved, generalized, and moved to libdiskfs. It is now also used by isofs and fatfs. The native fakeroot tool has been greatly improved. It now handles named sockets, and multiple corner cases related to permissions were identified and fixed. A new utility `rpcscan' has been introduced. It scans Mach servers and displays the RPCs handled by the associated demuxer. A long-standing synchronization issue involving the filesystem translators, libdiskfs, and libpager has been identified and fixed. The code has been updated to work with newer versions of the compiler and libc, and numerous bugs have been fixed throughout the code. Release tarballs may be downloaded from ftp://ftp.gnu.org/gnu/hurd/, http://ftp.gnu.org/gnu/hurd/, or checked out of Git, http://git.savannah.gnu.org/cgit/hurd/hurd.git.

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 1.6, NEWS: Version 1.6 (2015-10-31) The code has been updated to work with newer versions of the compiler, and numerous bugs have been fixed throughout the code. The lock debugging infrastructure has been revived and improved, and many locking issues have been fixed. The IPC tables and the hash table mapping objects to IPC entries have been replaced by radix trees. This addresses a scalability issue, as IPC tables required huge amounts of continuous virtual kernel memory. The kernel now allows non-privileged users to wire a small amount of memory. A bug hindering the eviction of inactive pages by the pageout daemon has been identified and fixed. The kernel now keeps timestamps relative to the system boot time. Among other things this fixes bogus uptime readings if the system time is altered. A reference leak in the exception handling mechanism has been identified and fixed. ANSI escape sequences are now handled when using `printf'. This fixes the formatting of messages printed by various Linux drivers.

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. More detailed: documentation.

GNU MIG 1.6, NEWS: Version 1.6 (2015-10-31) MIG now emits RPC lookup functions that are declared `static inline' improving compatibility with newer dialects of C.

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.
