------------------------------------------------------------ commit 0a5387a01165b46c8c85e7f7e2ddbe60a7f5db44 Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> Date: Mon Jun 27 19:29:40 2022 +0100 x86/spec-ctrl: Mitigate Branch Type Confusion when possible Branch Type Confusion affects AMD/Hygon CPUs on Zen2 and earlier. To mitigate, we require SMT safety (STIBP on Zen2, no-SMT on Zen1), and to issue an IBPB on each entry to Xen, to flush the BTB. Due to performance concerns, dom0 (which is trusted in most configurations) is excluded from protections by default. Therefore: * Use STIBP by default on Zen2 too, which now means we want it on by default on all hardware supporting STIBP. * Break the current IBPB logic out into a new function, extending it with IBPB-at-entry logic. * Change the existing IBPB-at-ctxt-switch boolean to be tristate, and disable it by default when IBPB-at-entry is providing sufficient safety. If all PV guests on the system are trusted, then it is recommended to boot with `spec-ctrl=ibpb-entry=no-pv`, as this will provide an additional marginal perf improvement. This is part of XSA-407 / CVE-2022-23825.

However, this is also very expensive in some cases, so we're going to want per-domain controls. Introduce SCF_ist_ibpb and SCF_entry_ibpb controls, adding them to the IST and DOM masks as appropriate. Also introduce X86_FEATURE_IBPB_ENTRY_{PV,HVM} to to patch the code blocks. For SVM, the STGI is serialising enough to protect against Spectre-v1 attacks, so no "else lfence" is necessary. VT-x will use use the MSR host load list, so doesn't need any code in the VMExit path. For the IST path, we can't safely check CPL==0 to skip a flush, as we might have hit an entry path before it's IBPB. As IST hitting Xen is rare, flush irrespective of CPL. A later path, SCF_ist_sc_msr, provides Spectre-v1 safety. For the PV paths, we know we're interrupting CPL>0, while for the INTR paths, we can safely check CPL==0. Only flush when interrupting guest context. An "else lfence" is needed for safety, but we want to be able to skip it on unaffected CPUs, so the block wants to be an alternative, which means the lfence has to be inline rather than UNLIKELY() (the replacement block doesn't have displacements fixed up for anything other than the first instruction). As with SPEC_CTRL_ENTRY_FROM_INTR_IST, %rdx is 0 on entry so rely on this to shrink the logic marginally. Update the comments to specify this new dependency. This is part of XSA-407.

Therefore, we cannot hold spec_ctrl_flags in %eax, and rely on only clobbering it after we're done with its contents. %rbx is available for use, and the more normal register to hold preserved information in. With %rax freed up, use it instead of %rdx for the RSB tmp register, and for the adjustment to spec_ctrl_flags. This leaves no use of %rdx, except as 0 for the upper half of WRMSR. In practice, %rdx is 0 from SAVE_ALL on all paths and isn't likely to change in the foreseeable future, so update the macro entry requirements to state this dependency. This marginal optimisation can be revisited if circumstances change. No practical change. This is part of XSA-407.
