  • 09155120c   kbuild: Clean up and speed up the localversion logic ... Browse Code »

    Now that we run scripts/setlocalversion during every build, it makes
    sense to move all the localversion logic there. This cleans up the
    toplevel Makefile and also makes sure that the script is called only
    once in 'make prepare' (previously, it would be called every time due to
    a variable expansion in an ifneq statement). No user-visible change is
    intended, unless one runs the setlocalversion script directly.

  • 880df92fa   scripts: use %_tmppath in "make rpm-pkg" ... Browse Code »

    The mkspec script hardcodes "/var/tmp" into the generated rpm spec file's
    BuildRoot. The user, however, may have a custom setting for %_tmppath,
    which should be used in BuildRoot. This patch changes mkspec's
    BuildRoot output to appropriately use %_tmppath.

  • db1d18657   scripts/package: deb-pkg: use fakeroot if available ... Browse Code »

    Running "make deb-pkg" requires setting KBUILD_PKG_ROOTCMD or
    becoming root oneself or it errors out. Unless already running
    as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a
    good default.

    With this patch applied, you can run "make oldconfig deb-pkg" as
    an ordinary user to build a binary package for an updated kernel
    tree and it should just work.

    fakeroot is too zealous by default in treating files as owned by
    root. Its wrapped stat() sets st_uid and st_gid to 0 for all
    files, which causes Git to go on a wild goose chase if
    CONFIG_LOCALVERSION_AUTO is set, checking if any file's content
    has changed along with its stat information. Avoid this by
    telling fakeroot to use the actual owner and group for
    preexisting files, by passing it the -u option.

  • 05ba4488a   scripts/package: add KBUILD_PKG_ROOTCMD variable ... Browse Code »

    Let the deb-pkg target acquire (fake) root privileges before
    running commands that need them. Without such privileges,
    deb-pkg errors out because chown fails.

    The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a
    command to run other commands with possibly fake elevated
    privileges. Since this is not needed for the tar-pkg and rpm-pkg
    targets, it is only used by deb-pkg. If it is not defined, the
    behavior is as before, and the user will have to rerun make as
    root.

    In other words, as a shortcut, instead of running 'make oldconfig &&
    make && fakeroot -u make deb-pkg', one can use the single command
    'make oldconfig deb-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"'.

  • 91d161857   scripts/package: tar-pkg: use tar --owner=root ... Browse Code »

    Use the --owner= and --group= options to make sure the entries in
    the built tar file are owned by root. Without this change, a
    careless sysadmin using the tar-pkg target can easily end up
    installing a kernel that is writable by the unprivileged user
    account used to build the kernel.

    Test that these options are understood before using them so that
    non-GNU versions of tar can still be used if the operator is
    appropriately cautious.

    The binrpm-pkg target (binary RPM only) fails when called with
    KBUILD_OUTPUT set. This patch makes it work.

    For the rpm-pkg target (source + binary RPM), building with
    KBUILD_OUTPUT set is not possible and also not needed as the
    actual build is done in a temporary directory anyway, so check
    that KBUILD_OUTPUT is not set in that case to avoid later errors.

  • b925dbfe3   kbuild: fix 'make rpm' when CONFIG_LOCALVERSION_AUTO=y and using SCM tree ... Browse Code »

    Running 'make rpm' fails when CONFIG_LOCALVERSION_AUTO=y and using a kernel source
    tree under SCM. This is due to KERNELRELEASE being different when the initial make
    is run and when make is run from rpmbuild.

    mkspec creates kernel.spec using KERNELRELEASE:

    echo "%files"
    echo '%defattr (-, root, root)'
    echo "%dir /lib/modules"
    echo "/lib/modules/$KERNELRELEASE"
    echo "/lib/firmware"
    echo "/boot/*"
    echo ""

    When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any
    additional version info from SCM. Next, the srctree is tarred up and SCM
    information is excluded.

    rpmbuild reruns make and in the process generates a new include/config/kernel.release
    and thus a new KERNELRELEASE. However this time the SCM information is gone so
    KERNELRELEASE no longer has the additional version information. When "make modules_install"
    runs, it uses the new KERNELRELEASE value to determine where to install the modules.
    This conflicts with where the spec file assumes they are going because of the
    mis-matching KERNELRELEASE versions.

    We are building an automated system to test kernels weekly and need to
    provide an rpm to our QA dept. We would like to use the ability to create
    kernel rpms already in the kernel's Makefile, but need the vmlinux file
    included in the rpm for later debugging.

    This patch adds a compressed vmlinux to the kernel rpm when doing a
    make rpm-pkg or binrpm-pkg and upon install places the vmlinux file in /boot.
