Changes to the previous version are: - Updated patch 2 and implemented wrappers around sev_es_get/put_ghcb() which will disable/enable IRQs when needed. - Updated patch 3 to now call the from_user and from_kernel functions of the VC handler directly from entry-asm. The previous version can be found here: https://lore.kernel.org/lkml/20210610091141.30322-1-joro@8bytes.org/ Changes are based on tip/x86/urgent. Please review. Thanks, Joerg Joerg Roedel (6): x86/sev-es: Fix error message in runtime #VC handler x86/sev-es: Make sure IRQs are disabled while GHCB is active x86/sev-es: Split up runtime #VC handler for correct state tracking x86/insn-eval: Make 0 a valid RIP for insn_get_effective_ip() x86/insn: Extend error reporting from insn_fetch_from_user[_inatomic]() x86/sev-es: Propagate #GP if getting linear instruction address failed arch/x86/entry/entry_64.S | 4 +- arch/x86/include/asm/idtentry.h | 29 ++--- arch/x86/kernel/sev.c | 207 ++++++++++++++++++++------------ arch/x86/kernel/umip.c | 10 +- arch/x86/lib/insn-eval.c | 22 ++-- 5 files changed, 156 insertions(+), 116 deletions(-) base-commit: efa165504943f2128d50f63de0c02faf6dcceb0d
