NetBSD 8.0發布：穩定性改進 數百個bug修復

­　　NetBSD 8.0 發布了，NetBSD 是一個免費的、安全的及高度可移植的開源 UNIX 操作系統，它適合于很多種平臺，從 64 位的 AlphaServers 及桌面系統到手持及嵌入式系統。它在設計上非常整潔，并擁有先進的特性，這使得它在業界和學術界都有口皆碑。用戶可通過完整的源代碼來獲得支持。很多應用程序都可容易地從 NetBSD Packages Collection 獲得。

­　　此次更新帶來了穩定性改進、數百個 bug 修復和許多新功能，主要內容包括：

­　　USB stack rework, USB3 support added.

­　　In-kernel audio mixer (audio_system(9)).

­　　Reproducible builds (MKREPRO, see mk.conf(5)).

­　　Full userland debug information (MKDEBUG, see mk.conf(5)) available. While most install media do not come with them (for size reasons), the debug and xdebug sets can be downloaded and extracted as needed later. They provide full symbol information for all base system and X binaries and libraries and allow better error reporting and (userland) crash analysis.

­　　PaX MPROTECT (W^X) memory protection enforced by default on some architectures with fine-grained memory protection and suitable ELF formats: i386, amd64, evbarm, landisk, pmax.

­　　PaX ASLR (Address Space Layout Randomization) enabled by default on: i386, amd64, evbarm, landisk, pmax, sparc64.

­　　Position independent executables by default for userland on: i386, amd64, arm, m68k, mips, sh3, sparc64.

­　　A new socket layer can(4) has been added for communication of devices on a CAN bus.

­　　A special pseudo interface ipsecif(4) for route-based VPNs has been added.

­　　Parts of the network stack have been made MP-safe. The kernel option NET_MPSAFE is required to enable this.

­　　Hardening of the network stack in general.

­　　Various WAPBL (the NetBSD file system "log" option) stability and performance improvements.

­　　詳情見發布公告。
