Jan Beulich <JBeulich@xxxxxxxx> Date: Wed Sep 20 10:36:06 2023 +0100 x86/shadow: defer releasing of PV's top-level shadow reference sh_set_toplevel_shadow() re-pinning the top-level shadow we may be running on is not enough (and at the same time unnecessary when the shadow isn't what we're running on): That shadow becomes eligible for blowing away (from e.g. shadow_prealloc()) immediately after the paging lock was dropped. Yet it needs to remain valid until the actual page table switch occurred. Propagate up the call chain the shadow entry that needs releasing eventually, and carry out the release immediately after switching page tables. Handle update_cr3() failures by switching to idle pagetables. Note that various further uses of update_cr3() are HVM-only or only act on paused vCPU-s, in which case sh_set_toplevel_shadow() will not defer releasing of the reference. While changing the update_cr3() hook, also convert the "do_locking" parameter to boolean. This is CVE-2023-34322 / XSA-438.

In the case of #DE, the latched result from the previous DIV to execute will be forwarded speculatively. This is an interesting covert channel that allows two threads to communicate without any system calls. In also allows userspace to obtain the result of the most recent DIV instruction executed (even speculatively) in the core, which can be from a higher privilege context. Scrub the result from the divider by executing a non-faulting divide. This needs performing on the exit-to-guest paths, and ist_exit-to-Xen. Alternatives in IST context is believed safe now that it's done in NMI context. This is XSA-439 / CVE-2023-20588.

In order to compensate, issue VERW when exiting to Xen from an IST entry. SPEC_CTRL_EXIT_TO_XEN already has two reads of spec_ctrl_flags off the stack, and we're about to add a third. Load the field into %ebx, and list the register as clobbered. %r12 has been arranged to be the ist_exit signal, so add this as an input dependency and use it to identify when to issue a VERW.

This register is zero elsewhere in the entry/exit asm, so it only needs setting in the IST path. As this is subtle and fragile, add check_ist_exit() to be used in debugging builds to cross-check that the ist_exit boolean matches the entry vector. Write check_ist_exit() it in C, because it's debug only and the logic more complicated than I care to maintain in asm. For now, we only need to use this signal in the exit-to-Xen path, but some exit-to-guest paths happen in IST context too. Check the correctness in all exit paths to avoid the logic bit-rotting.

The IST-ness in %r12 doesn't survive into the next context, and is a stale value C. This shows up in Gitlab CI for the Clang build: https://gitlab.com/xen-project/people/andyhhp/xen/-/jobs/5112783827 and in OSSTest for GCC 8: http://logs.test-lab.xenproject.org/osstest/logs/183045/test-amd64-amd64-xl-qemuu-debianhvm-amd64/serial-pinot0.log There's no straightforward way to reconstruct the IST-exit-ness on the exit-to-guest path after a context switch.
