From bb114a3b92a96875dc71e5e4925bedba5c02f958 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Thu, 29 Jun 2023 17:58:18 +0200 Subject: Implement shim image load protocol Define a new protocol for loading and starting images, encapsulating shim's PE loading facilities and verification/authentication against the same set of certificates that shim_lock::verify() authenticates against. This removes the need for loaders like GRUB to implement their own PE loader in order to be able to invoke loaded images as PE applications, rather than implementing a bespoke OS dependent handover protocol (e.g., invoke Linux via its EFI stub) Signed-off-by: Ard Biesheuvel --- lib/guid.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'lib') diff --git a/lib/guid.c b/lib/guid.c index 6e92cea3..1dc90ca9 100644 --- a/lib/guid.c +++ b/lib/guid.c @@ -35,5 +35,7 @@ EFI_GUID SECURITY_PROTOCOL_GUID = { 0xA46423E3, 0x4617, 0x49f1, {0xB9, 0xFF, 0xD EFI_GUID SECURITY2_PROTOCOL_GUID = { 0x94ab2f58, 0x1438, 0x4ef1, {0x91, 0x52, 0x18, 0x94, 0x1a, 0x3a, 0x0e, 0x68 } }; EFI_GUID EFI_MEMORY_ATTRIBUTE_PROTOCOL_GUID = { 0xf4560cf6, 0x40ec, 0x4b4a, {0xa1, 0x92, 0xbf, 0x1d, 0x57, 0xd0, 0xb1, 0x89} }; EFI_GUID SHIM_LOCK_GUID = {0x605dab50, 0xe046, 0x4300, {0xab, 0xb6, 0x3d, 0xd8, 0x10, 0xdd, 0x8b, 0x23 } }; +EFI_GUID SHIM_IMAGE_LOADER_GUID = {0x1f492041, 0xfadb, 0x4e59, {0x9e, 0x57, 0x7c, 0xaf, 0xe7, 0x3a, 0x55, 0xab } }; +EFI_GUID SHIM_LOADED_IMAGE_GUID = {0x6e6baeb8, 0x7108, 0x4179, {0x94, 0x9d, 0xa3, 0x49, 0x34, 0x15, 0xec, 0x97 } }; EFI_GUID MOK_VARIABLE_STORE = {0xc451ed2b, 0x9694, 0x45d3, {0xba, 0xba, 0xed, 0x9f, 0x89, 0x88, 0xa3, 0x89} }; EFI_GUID SECUREBOOT_EFI_NAMESPACE_GUID = {0x77fa9abd, 0x0359, 0x4d32, {0xbd, 0x60, 0x28, 0xf4, 0xe7, 0x8f, 0x78, 0x4b} }; -- cgit v1.2.3
