x86/sev-es: Use __copy_from_user_inatomic() (2021-03-09 12:37:54 +0100)
----------------------------------------------------------------
- A couple of SEV-ES fixes and robustifications: verify usermode stack
pointer in NMI is not coming from the syscall gap, correctly track IRQ
states in the #VC handler and access user insn bytes atomically in same
handler as latter cannot sleep.
- Balance 32-bit fast syscall exit path to do the proper work on exit
and thus not confuse audit and ptrace frameworks.
- Two fixes for the ORC unwinder going "off the rails" into KASAN
redzones and when ORC data is missing.
----------------------------------------------------------------
Andy Lutomirski (1):
x86/entry: Fix entry/exit mismatch on failed fast 32-bit syscalls
Joerg Roedel (4):
x86/sev-es: Introduce ip_within_syscall_gap() helper
x86/sev-es: Check regs->sp is trusted before adjusting #VC IST stack
x86/sev-es: Correctly track IRQ states in runtime #VC handler
x86/sev-es: Use __copy_from_user_inatomic()
Josh Poimboeuf (2):
x86/unwind/orc: Disable KASAN checking in the ORC unwinder, part 2
x86/unwind/orc: Silence warnings caused by missing ORC data
