Default is either seccomp or prctl (if seccomp is # disabled in Kconfig). prctl allows mitigation opt-in, seccomp # enables the migitation for sandboxed processes. # # - Rework the code to handle the conditional STIBP/IBPB control and # remove the now unused ptrace_may_access_sched() optimization # attempt # # - Disable STIBP automatically when SMT is disabled # # - Optimize the switch_to() logic to avoid MSR writes and invocations # of __switch_to_xtra(). # # - Make the asynchronous speculation TIF updates synchronous to # prevent stale mitigation state. # # As a general cleanup this also makes retpoline directly depend on # compiler support and removes the 'minimal retpoline' option which just # pretended to provide some form of security while providing none" # # * 'x86-pti-for-linus'
