The xnu make system can build kernel based on KERNEL_CONFIGS & ARCH_CONFIGS variables as arguments. Here is the syntax: make SDKROOT=<sdkroot> ARCH_CONFIGS=<arch> KERNEL_CONFIGS=<variant> Where: <sdkroot>: path to MacOS SDK on disk. (defaults to /) <variant>: can be debug, develop...

大多数现代操作系统遵循这种设计范畴,微软公司开发的Windows操作系统就是一个很好的例子。另外还有XNU,运行在苹果Mac OS X上的内核,也是一个混合内核。 混合内核的例子: BeOS 内核 ,DragonFly BSD,ReactOS 内核 Windows NT、Windows 2000、Windows XP、Windows Server 2003以及Windows Vista等基于NT技术的操作系统。 ...
XNU kernel is part of the Darwin operating system for use in OS X and iOS operating systems. XNU is an acronym for XNU is Not Unix. XNU is a hybrid kernel combining the Mach kernel developed at Carnegie Mellon University with components from FreeBSD and C++ API for writing drivers called...
首先,macOS的内核XNU实际上是由苹果公司自行开发的,而XNU内核中包含了一些来自于BSD和Mach的组件。而BSD是一种Unix的衍生系统,Mach是一个微内核操作系统内核。因此,macOS的XNU内核融合了来自不同操作系统的设计理念,这也使得macOS具有一些类Unix系统的特性。
macOS kernel 的特色官方总结为: XNU。意思是 “XNU 不是 Unix”。根据苹果的 Github 页面, XNU 是 “一个混合内核, 奠基于卡耐基·梅隆大学开发的 Mach kernel , 它的组件来自 FreeBSD 和用于编写驱动程序的 C++ API “。BSD 子系统部分的代码 “通常作为微核心系统中实现用户空间服务”。Mach 部分的代码则负...

However, discovering XNU kernel vulnerabilities is always very challenging, and the main approach in practice is still manual analysis, which obviously is not a scalable method. In this paper, we perform an in-depth empirical study on the 406 published XNU kernel vulnerabilities to identify ...
Zone is a very important unit in XNU (i.e., the kernel of iOS and macOS) memory management. It is used to quickly allocate and release frequently used fixed-size objects. The structure of the zone is defined as follows: free_element points to a linked list that records the freed elemen...
