First make ZO (arch/x86/boot/compressed/vmlinux) data region is not overwritten by VO (vmlinux) after decompress. So could pass data from ZO to VO. Second one is second try for kaslr_setup_data support. Patch 3-11, are kaslr clean up and enable ident mapping for He's patches. kill run_size calculation shell scripts. create new ident mapping for kasl 64bit, so we can cover above 4G random kernel base, also don't need to track pagetable for 64bit bootloader (patched grub2 or kexec). that will make mem_avoid handling simple. Also put 7 patches from He that support random random, as I already used his patches to test the ident mapping code, and could save some rebase work for him. also at: git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-4.0-rc5-aslr Thanks Yinghai Baoquan He (7): x86, kaslr: Fix a bug that relocation can not be handled when kernel is loaded above 2G x86, kaslr: Introduce struct slot_area to manage randomization slot info x86, kaslr: Add two functions which will be used later x86, kaslr: Introduce fetch_random_virt_offset to randomize the kernel text mapping address x86, kaslr: Randomize physical and virtual address of kernel separately x86, kaslr: Add support of kernel physical address randomization above 4G x86, kaslr: Remove useless codes Jiri Kosina (1): x86, kaslr: Propagate base load address calculation v2 Yinghai Lu (11): x86, boot: Make data from decompress_kernel stage live longer x86, boot: Simplify run_size calculation x86, kaslr: Kill not used run_size related code. x86, kaslr: Use output_run_size x86, kaslr: Consolidate mem_avoid array filling x86, boot: Move z_extract_offset calculation to header.S x86, kaslr: Get correct max_addr for relocs pointer x86, boot: Split kernel_ident_mapping_init to another file x86, 64bit: Set ident_mapping for kaslr x86, boot: Add checking for memcpy x86, kaslr: Allow random address could be below loaded address arch/x86/boot/Makefile | 13 +- arch/x86/boot/compressed/Makefile | 19 ++- arch/x86/boot/compressed/aslr.c | 281 ++++++++++++++++++++++++--------- arch/x86/boot/compressed/head_32.S | 14 +- arch/x86/boot/compressed/head_64.S | 15 +- arch/x86/boot/compressed/misc.c | 71 +++++---- arch/x86/boot/compressed/misc.h | 32 ++-- arch/x86/boot/compressed/misc_pgt.c | 91 +++++++++++ arch/x86/boot/compressed/mkpiggy.c | 28 +--- arch/x86/boot/compressed/string.c | 28 +++- arch/x86/boot/compressed/vmlinux.lds.S | 2 + arch/x86/boot/header.S | 43 ++++- arch/x86/include/asm/aslr.h | 10 ++ arch/x86/include/asm/boot.h | 19 +++ arch/x86/include/asm/page.h | 5 + arch/x86/include/asm/page_types.h | 2 + arch/x86/include/uapi/asm/bootparam.h | 1 + arch/x86/kernel/asm-offsets.c | 1 + arch/x86/kernel/module.c | 10 +- arch/x86/kernel/setup.c | 27 +++- arch/x86/kernel/vmlinux.lds.S | 1 + arch/x86/mm/ident_map.c | 74 +++++++++ arch/x86/mm/init_64.c | 74 +-------- arch/x86/tools/calc_run_size.sh | 42 ----- 24 files changed, 610 insertions(+), 293 deletions(-) create mode 100644 arch/x86/boot/compressed/misc_pgt.c create mode 100644 arch/x86/include/asm/aslr.h create mode 100644 arch/x86/mm/ident_map.c delete mode 100644 arch/x86/tools/calc_run_size.sh -- 1.8.4.5 -- To unsubscribe from this list: send the line "unsubscribe linux-efi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
