From 04cc7914f2697cdc43b1cd5e0d7ab73893327966 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Thu, 12 Nov 2020 00:29:58 +0100 Subject: [PATCH] efi_selftest: implement exception test for sandbox Provide a unit test that causes an illegal instruction to occur. The test can be run with the following commands: => setenv efi_selftest exception => bootefi selftest This might be the output: Executing 'exception' EFI application triggers exception. Illegal instruction pc = 0x1444d016, pc_reloc = 0xffffaa078e8dd016 UEFI image [0x0000000000000000:0xffffffffffffffff] '/\selftest' UEFI image [0x000000001444b000:0x0000000014451fff] pc=0x2016 '/bug.efi' Resetting ... It would tell us that the exception was triggered by an instruction 0x2016 bytes after the load address of the binary with filename /bug.efi.
