  • de5b56ba5   kernel: build bin2c based on config option CONFIG_BUILD_BIN2C ... Browse Code »

    currently bin2c builds only if CONFIG_IKCONFIG=y. But bin2c will now be
    used by kexec too. So make it compilation dependent on CONFIG_BUILD_BIN2C
    and this config option can be selected by CONFIG_KEXEC and CONFIG_IKCONFIG.

  • 8370edea8   bin2c: move bin2c in scripts/basic ... Browse Code »

    This patch series does not do kernel signature verification yet. I plan
    to post another patch series for that. Now distributions are already
    signing PE/COFF bzImage with PKCS7 signature I plan to parse and verify
    those signatures.

    Primary goal of this patchset is to prepare groundwork so that kernel
    image can be signed and signatures be verified during kexec load. This
    should help with two things.

    - It should allow kexec/kdump on secureboot enabled machines.

    - In general it can help even without secureboot. By being able to verify
    kernel image signature in kexec, it should help with avoiding module
    signing restrictions. Matthew Garret showed how to boot into a custom
    kernel, modify first kernel's memory and then jump back to old kernel and
    bypass any policy one wants to.

    This patch (of 15):

    Kexec wants to use bin2c and it wants to use it really early in the build
    process. See arch/x86/purgatory/ code in later patches.

    So move bin2c in scripts/basic so that it can be built very early and
    be usable by arch/x86/purgatory/

  • 2ab8a9966   kbuild: fixdep: support concatenated dep files ... Browse Code »

    The current use-case for fixdep is: a source file is run through a single
    processing step, which creates a single dependency file as a side-effect,
    which fixdep transforms into the file used by the kernel build process.

    In order to transparently run the C pre-processor on device-tree files,
    we wish to run both gcc -E and dtc on a source file in a single rule.
    This generates two dependency files, which must be transformed together
    into the file used by the kernel build process. This change modifies
    fixdep so it can process the concatenation of multiple separate input
    dependency files, and produce a correct unified output.

    The code changes have the slight benefit of transforming the loop in
    parse_dep_file() into more of a lexer/tokenizer, with the loop body being
    more of a parser. Previously, some of this logic was mixed together
    before the loop. I also added some comments, which I hope are useful.

    Benchmarking shows that on a cross-compiled ARM tegra_defconfig build,
    there is less than 0.5 seconds speed decrease with this change, on top
    of a build time of ~2m24s. This is probably within the noise.

  • 6a5be57f0   fixdep: fix extraneous dependencies ... Browse Code »

    The introduction of include/linux/kconfig.h created 3 extraneous
    dependencies:
    include/config/.h
    include/config/h.h
    include/config/foo.h

    Fix this by excluding kconfig.h from fixdep calculations.
