ima: force signature verification when CONFIG_KEXEC_SIG is configured
[ Upstream commit af16df54b89dee72df253abc5e7b5e8a6d16c11c ]
Currently, an unsigned kernel could be kexec'ed when IMA arch specific
policy is configured unless lockdown is enabled. Enforce kernel
signature verification check in the kexec_file_load syscall when IMA
arch specific policy is configured.
Fixes: 99d5cadfde2b ("kexec_file: split KEXEC_VERIFY_SIG into KEXEC_SIG and KEXEC_SIG_FORCE")
