Тег: netbsd

The portable NetBSD operating system has reached a new milestone with the release of NetBSD 10.0. The new version introduces a number of performance and security improvements: "Benchmarks of NetBSD 10 show huge performance and scalability gains over NetBSD 9.x, especially on multiprocessor and multicore systems, for compute and filesystem-bound applications. Areas of improvement included: switched the kernel's file path lookup cache to use faster per-directory red-black trees; improved scheduler performance, including the ability to more appropriately spread load on a mixture of slow and fast cores (e.g. big.LITTLE Arm CPUs); various optimizations for the machine-independent virtual memory system; improved tracking of clean/dirty pages, speeding up fsync(2) on large files by orders of magnitude; improved parallelization - rewritten page allocator with awareness of CPU topology, replaced global counters with per-CPU counters, and reduced lock contention; improved the performance of the select(2) and poll(2) system calls; improved the performance of tmpfs; implemented lazy update of atime/mtime; various optimizations of architecture-dependent x86 and AArch64 code, vastly improved network and I/O throughput on aarch64...."

NetBSD 10.0 RC2

NetBSD is a highly portable operating system which offers a minimal and clean design. The project has published its second (and probably final) release candidate for NetBSD 10.0. Among the enhancements in this snapshot are cyptographic updates and an experimental implementation of WireGuard. "Compatibility with WireGuard: A new interface, wg(4), provides a VPN tunnel compatible with the WireGuard specification. The driver is experimental and needs more testing. A userspace implementation using a rump kernel server is also included, see wg-userspace(4)/ The NetBSD implementation works with WireGuard implementations used by commercial VPN providers, Android, Linux, and more. Stronger, faster cryptography: Added an implementation of the Adiantum cipher for efficient disk encryption with cgd(4) on systems without AES acceleration. Added support for shared keys to cgdconfig(8), allowing multiple derived subkeys to be used across multiple drives. Switched the default password hashing algorithm to Argon2id, winner of the Password Hashing Competition. The algorithm's hardness automatically scales with system performance. Added support for Argon2id to cgdconfig(8) for use in password-based disk encryption. The kernel now takes advantage of CPU acceleration and vectorization for common cryptographic algorithms on x86 and Arm, including AES and ChaCha. All in-kernel implementations of AES are now constant-time on all architectures. Swap encryption is now automatic using the vm.swap_encrypt=1 sysctl(8) variable."

NetBSD 10.0 RC1

"The NetBSD project is pleased to announce the first release candidate of the upcoming 10.0 release, please help testing. The netbsd-10 release branch is more than a year old now, so it is high time the 10.0 release makes it to the front stage. This matches the long time it took for the development branch to get ready for branching, a lot of development went into this new release. This also caused the release anouncement to be one of the longest we ever did. Especially on amd64 machines, please notes that we got a new DRM/KMS subsystem version and this may lead to fallout on some hardware. Unfortunately not all known bugs from the release engineering pre-release task list could be fixed in time for this release - we will continue to improve the current state and hope to have more of them solved for the next (10.1) release."

The NetBSD project creates a highly portable operating system which runs on a wide range of processors. The project has published a new version in the 9.x series: NetBSD 9.3. "Aside from many bug fixes, 9.3 includes backported improvements to suspend and resume support, various minor additions of new hardware to existing device drivers, compatibility with UDF file systems created on Windows 10, enhanced support for newer Intel Gigabit Ethernet chipsets, better support for new Intel and AMD Zen 3 chipsets, support for configuring connections to Wi-Fi networks using sysinst(8), support for wsfb-based X11 servers on the Commodore Amiga, and minor performance improvements for the Xen hypervisor."
