What is retpoline kernel? What Is a Retpoline? A retpoline is a return trampoline that makes use of an infinite loop that is never executed to prevent a CPU from speculating the target of an indirect jump. This system also uses a Return Stack Buffer (RSB) as a prediction structure, similar to a branch predictor for return instructions.
What is Repoline? • Retpoline stands for return and trampoline. • The goal of a retpoline sequence is to control how the CPU performs speculation when executing “jmp” and “call”.
What is reptoline? A retpoline is designed to protect against the branch target injection (CVE-2017-5715) exploit. This is an attack where an indirect branch instruction in the kernel is used to force the speculative execution of an arbitrary chunk of code.
Is Linux vulnerable to Spectre? Security. Linux can deal with Meltdown and Spectre, the fundamental chip security problems, but that doesn’t mean Linux’s developers are happy about it.

Does Linux use ZFS?

Is ZFS stable on Linux?
ZFS is the only filesystem option that is stable, protects your data, is proven to survive in most hostile environments and has a lengthy usage history with well understood strengths and weaknesses. ZFS has been (mostly) kept out of Linux due to CDDL incompatibility with Linux’s GPL license.
