As of now it’s all tied up!

Cool to see the jailed bhyve feature, which I wrote, used in unique ways.

Syzkaller is much needed tool for #Linux kernel testing & debugging. With some work, it can also be enhanced to find bugs in specific drivers, such as #V4L2. Here's how: http://col.la/k3gw8 #syzkaller #kernel #debugging

kcov is limited to architectures using Clang as their default compiler and is not enabled by default.
With help from mpi@, thanks!
