First 3 patches 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.
The 4th one is fixing kaslr_enabled accessing. Old code is using address as value wrongly. Last 3 patches are the base for kaslr supporting kernel above 4G. 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. Please put first 4 patches into tip/x86/urgent to v4.0 Last 3 patches should go to tip/x86/kasl and to v4.1, but you may need to pull x86/urgent to x86/kasl, as them depends on first 4 patches. He could rebase his patches about kasl on top those patches. git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-4.0-rc2-aslr Thanks Yinghai Lu Yinghai Lu (7): x86, kaslr: Use init_size instead of run_size x86, boot: Move ZO to end of buffer x86, boot: Don't overlap VO with ZO data x86, kaslr: Access the correct kaslr_enabled variable x86, kaslr: Consolidate mem_avoid array filling x86, boot: Split kernel_ident_mapping_init to another file x86, kaslr, 64bit: Set new or extra ident_mapping arch/x86/boot/Makefile | 2 +- arch/x86/boot/compressed/Makefile | 4 +- arch/x86/boot/compressed/aslr.c | 48 ++++++++++++----- arch/x86/boot/compressed/head_32.S | 16 ++++-- arch/x86/boot/compressed/head_64.S | 17 +++--- arch/x86/boot/compressed/misc.c | 15 +++--- arch/x86/boot/compressed/misc.h | 4 +- arch/x86/boot/compressed/misc_pgt.c | 98 ++++++++++++++++++++++++++++++++++ arch/x86/boot/compressed/mkpiggy.c | 16 ++---- arch/x86/boot/compressed/vmlinux.lds.S | 2 + arch/x86/boot/header.S | 9 ++-- arch/x86/include/asm/boot.h | 19 +++++++ arch/x86/include/asm/page.h | 5 ++ arch/x86/kernel/asm-offsets.c | 1 + arch/x86/kernel/setup.c | 13 ++++- 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 --------------- 19 files changed, 288 insertions(+), 172 deletions(-) create mode 100644 arch/x86/boot/compressed/misc_pgt.c 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-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
