The Linux kernel Berkeley Packet Filter (BPF) Just-In-Time (JIT) compiler has been an important focus of the project, since it is widely used in the kernel and has seen successful attacks in the past. In 2012, the first JIT spray attack against the Linux BPF/JIT compiler was presented. Consequently, some countermeasures were implemented in the. In his linux.conf.au 2017 talk [YouTube] on the eBPF in-kernel virtual machine, Brendan Gregg proclaimed that "super powers have finally come to Linux". Getting eBPF to that point has been a long road of evolution and design.
