On Intel Skylake-era systems the mitigation covers most, but not all,
cases. See :ref:`[3] <spec_ref3>` for more details.
On CPUs with hardware mitigation for Spectre variant 2 (e.g. Enhanced
IBRS on x86), retpoline is automatically disabled at run time.
On CPUs with hardware mitigation for Spectre variant 2 (e.g. IBRS
or enhanced IBRS on x86), retpoline is automatically disabled at run time.
Systems which support enhanced IBRS (eIBRS) enable IBRS protection once at
boot, by setting the IBRS bit, and they're automatically protected against
Spectre v2 variant attacks, including cross-thread branch target injections
on SMT systems (STIBP). In other words, eIBRS enables STIBP too.
Legacy IBRS systems clear the IBRS bit on exit to userspace and
therefore explicitly enable STIBP for that
The retpoline mitigation is turned on by default on vulnerable
CPUs. It can be forced on or off by the administrator

For Spectre variant 2 mitigation, individual user programs
can be compiled with return trampolines for indirect branches.
This protects them from consuming poisoned entries in the branch
target buffer left by malicious software. Alternatively, the
programs can disable their indirect branch speculation via prctl()
(See :ref:`Documentation/userspace-api/spec_ctrl.rst <set_spec_ctrl>`).
target buffer left by malicious software.
On legacy IBRS systems, at return to userspace, implicit STIBP is disabled
because the kernel clears the IBRS bit. In this case, the userspace programs
can disable indirect branch speculation via prctl() (See
:ref:`Documentation/userspace-api/spec_ctrl.rst <set_spec_ctrl>`).
On x86, this will turn on STIBP to guard against attacks from the
sibling thread when the user program is running, and use IBPB to
flush the branch target buffer when switching to/from the program.
