We could add another hack to hide kexts in kextstat, and that makes it even worse. Running kextstat does shows all loaded kexts, so it’s not that hidden, but cleaner anyway. This way unsigned kexts won’t show up in System Information/Software/Extensions, which in my view makes it somewhat harder to detect. I use /Extra/Extensions for unsigned kexts, so that the /Library/Extensions and /System/Library/Extensions directories can be kept vanilla/untouched.

This means that I run my hack with maximum System Integrity Protection (SIP) activated (no rootless=0 boot argument/runtime/NVRAM variables to bypass the code signing restrictions) with the following unsigned kexts: This time I did it differently, and this blog post is a short and simple POC (proof of concept) to show you that bypassing Apple’s rather strict kext signing restrictions still works. Since the namespace infrastructure has no persistence, new entry points have to be added to manage the list of datasets when a new namespace is created.I have found a very simple way to bypass Apple’s kext signing in El Capitan, like I did before in Yosemite and Mavericks before that. This allows many of the existing zone paths in ZFS to be reused. In the Solaris Porting Layer (SPL) portion of ZFS on Linux, we added zone interfaces and associate zone objects with dataset namespaces. We introduce a *dataset namespace*, which functions as an analogue of a zone identifier. We are building a container platform based on Linux and OpenZFS, and one functionality gap we're addressing is to provide ZFS delegation to processes running inside Linux containers. Native *container* frameworks on Linux work by composing sets of namespaces and cgroups and creating processes using them. Processes are also bound to *cgroups*, or control groups, which form a heirarchy for each available resource control. Each process is associated with a list of *namespaces*, each of which isolates a specific type of resource, such as mountpoints and network interfaces. Instead, Linux provides a set of primitives for resource isolation and control. The Linux kernel is different in that there is no first-order object corresponding a specific virtual environment. A list of ZFS datasets can be *delegated* to a zone, which makes them visible to processes inside the zone and allows administrative operations on the datasets and their children. All system calls can take advantage of zone awareness to isolate resources and process privileges. Zones are backed by a persistent configuration store. On illumos, *zones* are sandboxed environments encompassing filesystem, network, IPC and other resources, as well as fine-grained resource controls.
