A new binary, xen.mb.efi, is built. It contains the mb2 header as well as a hand-crafted PE/COFF header. The dom0 kernel is verified using the shim lock protocol. I followed with v2 feedback and attempted to convert the PE/COFF header into C instead of ASM. Unfortunately, this was only possible for the first part (Legacy) of the PE/COFF header. The other parts required addresses only available at link time (such as __2M_rwdata_end, __pe_SizeOfImage, efi_mb_start address, etc...), which effectively ruled out C. The biggest difference between v2 and v3 is that in v3 we do not attempt to merge xen.mb.efi and xen.efi into a single binary. Instead, this will be left to a future patch set, unless requested otherwise. [1]: https://lists.xen.org/archives/html/xen-devel/2018-06/msg01292.html Changes in v3: - add requested comment clarification - remove unnecessary fake data from PE/COFF head (like linker versions) - macro-ize and refactor Makefile according to Jan's feedback - break PE/COFF header into its own file - shrink the PE/COFF to start 0x40 instead of 0x80 (my tests showed this function with no problem, on a live nested vm or using objdump/objcopy) - support SOURCE_EPOCH for posix time - removed `date` invocation that would break on FreeBSD - style changes - And obviously, ported to current HEAD Daniel Kiper (5): xen: add XEN_BUILD_POSIX_TIME xen/x86: manually build xen.mb.efi binary xen/x86: add some addresses to the Multiboot header xen/x86: add some addresses to the Multiboot2 header xen/x86/efi: Verify dom0 kernel with SHIM_LOCK protocol in efi_multiboot2() xen/Makefile | 22 ++++--- xen/arch/x86/Makefile | 7 +- xen/arch/x86/arch.mk | 2 + xen/arch/x86/boot/Makefile | 1 + xen/arch/x86/boot/head.S | 53 +++++++++++++-- xen/arch/x86/boot/pecoff.S | 123 +++++++++++++++++++++++++++++++++++ xen/arch/x86/efi/efi-boot.h | 30 ++++++++- xen/arch/x86/efi/stub.c | 17 ++++- xen/arch/x86/xen.lds.S | 34 ++++++++++ xen/common/efi/boot.c | 19 ++++-- xen/include/xen/compile.h.in | 1 + xen/include/xen/efi.h | 1 + 12 files changed, 283 insertions(+), 27 deletions(-) create mode 100644 xen/arch/x86/boot/pecoff.S -- 2.30.0
