GNU Hurd 0.8, GNU Mach 1.7, GNU MIG 1.7 released.

We're pleased to announce new releases!

GNU Hurd 0.8, NEWS: Version 0.8 (2016-05-18) The netfs library is using the lockless reference-counting primitives for both peropen and node objects now, and the global reference counting lock has been removed. The integer hashing library gained a new interface to use non-integer keys. It is now used in libdiskfs' and nfs' node cache, and the ftpfs translator. Several bugs in our native fakeroot tool have been fixed improving stability and correctness of the translation. The devnode translator and the hurd-slab library have been merged into this repository. The code has been cleaned up, and we fixed numerous bugs, most notably a crash in pfinet, a locking bug in libdiskfs, and an out-of-bounds access in ext2fs' block cache.

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 1.7, NEWS: Version 1.7 (2016-05-18) The code has been updated to work with newer versions of GCC, and numerous bugs have been fixed throughout the code, including a pageout deadlock. The code uses integer types from <stdint.h> now instead of the old Mach types. The VM cache policy change has been merged. The kernel now caches unreferenced VM objects unconditionally instead of using a fixed limit. The physical page allocator of the X15 kernel has been integrated, and is now used directly by the slab allocator. This increases the kernel heap addressing important scalability issues. The gsync synchronization mechanism was added, similar to the Linux kernel's futexes, to allow efficient and powerful userland synchronization. Support for profiling kernel code from userland through sampling was added.

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 1.7, NEWS: Version 1.7 (2016-05-18) MIG now has a test suite. It includes a set of valid and invalid definition files that MIG will try to process. For valid definitions, GCC will compile the stubs to check if valid C code was generated. The generated code uses integer types from <stdint.h> now instead of the old Mach types. Code that was hard-coding the word size has been identified and fixed. Support for the obsolete kinds of RPC routines 'functions', 'procedures', and 'simple procedures' has been removed. MIG now emits code that casts objects translated from capabilities to the correct C type.

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.
