  • 303395ac3   x86: Generate system call tables and unistd_*.h from tables ... Browse Code »
    86

    Generate system call tables and unistd_*.h automatically from the
    tables in arch/x86/syscalls. All other information, like NR_syscalls,
    is auto-generated, some of which is in asm-offsets_*.c.

    This allows us to keep all the system call information in one place,
    and allows for kernel space and user space to see different
    information; this is currently used for the ia32 system call numbers
    when building the 64-bit kernel, but will be used by the x32 ABI in
    the near future.

    This also removes some gratuitious differences between i386, x86-64
    and ia32; in particular, now all system call tables are generated with
    the same mechanism.

  • 08c2b394b   x86, build: Disable -fPIE when compiling with CONFIG_CC_STACKPROTECTOR=y ... Browse Code »

    The arch/x86/Makefile uses scripts/gcc-x86_$(BITS)-has-stack-protector.sh
    to check if cc1 supports -fstack-protector. When -fPIE is passed to cc1,
    these scripts fail causing stack protection to be disabled even when it
    is available.

    This fix is similar to commit c47efe5548abbf53c2f66e06dcb46183b11d6b22

    The newer assemblers support the .cfi_sections directive so we can put
    the CFI from .S files into the .debug_frame section that is preserved
    in unstripped vmlinux and in separate debuginfo, rather than the
    .eh_frame section that is now discarded by vmlinux.lds.S.

    For some reason the 64-bit tree was doing this differently and
    I can't see why it would need to.

    This correct behaviour when you have two GPUs plugged in and
    32-bit put the console in one place and 64-bit in another.

  • 14a3f40aa   x86: Remove STACKPROTECTOR_ALL ... Browse Code »

    STACKPROTECTOR_ALL has a really high overhead (runtime and stack
    footprint) and is not really worth it protection wise (the
    normal STACKPROTECTOR is in effect for all functions with
    buffers already), so lets just remove the option entirely.

  • caa27b66b   kbuild: use INSTALLKERNEL to select customized installkernel script ... Browse Code »

    Replace the use of CROSS_COMPILE to select a customized
    installkernel script with the possibility to set INSTALLKERNEL
    to select a custom installkernel script when running make:

    make INSTALLKERNEL=arm-installkernel install

    With this patch we are now more consistent across
    different architectures - they did not all support use
    of CROSS_COMPILE.

    The use of CROSS_COMPILE was a hack as this really belongs
    to gcc/binutils and the installkernel script does not change
    just because we change toolchain.

    The use of CROSS_COMPILE caused troubles with an upcoming patch
    that saves CROSS_COMPILE when a kernel is built - it would no
    longer be installable.
    [Thanks to Peter Z. for this hint]

    This patch undos what Ian did in commit:

    0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46
    ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh")

    The patch has been lightly tested on x86 only - but all changes
    looks obvious.

    When CONFIG_X86_DECODER_SELFTEST=y, Kbuild builds a test harness of x86

    The test compares the results of objdump and x86 instruction decoder

  • dfec072ec   kmemcheck: add the kmemcheck core ... Browse Code »

    General description: kmemcheck is a patch to the linux kernel that
    detects use of uninitialized memory. It does this by trapping every
    read and write to memory that was allocated dynamically (e.g. using
    kmalloc()). If a memory address is read that has not previously been
    written to, a message is printed to the kernel log.

    Thanks to Andi Kleen for the set_memory_4k() solution.

    Andrew Morton suggested documenting the shadow member of struct page.

    It is common to use "make install" in restricted environments which
    differ from the one which was actually used to build the kernel. In
    such environments it is highly undesirable to trigger a rebuild of any
    part of the system. Worse, the rebuild may be spurious, triggered by
    differences in the environment.

    Impact: no default -fno-stack-protector if stackp is enabled, cleanup

    Stackprotector make rules had the following problems.

    * cc support test and warning are scattered across makefile and
    kernel/panic.c.

    * -fno-stack-protector was always added regardless of configuration.

    Update such that cc support test and warning are contained in makefile
    and -fno-stack-protector is added iff stackp is turned off. While at
    it, prepare for 32bit support.

  • b40a4392a   stackprotector: turn not having the right gcc into a #warning ... Browse Code »

    If the user selects the stack-protector config option, but does not have
    a gcc that has the right bits enabled (for example because it isn't build
    with a glibc that supports TLS, as is common for cross-compilers, but also
    because it may be too old), then the runtime test fails right now.

    This patch adds a warning message for this scenario. This warning accomplishes
    two goals
    1) the user is informed that the security option he selective isn't available
    2) the user is suggested to turn of the CONFIG option that won't work for him,
    and would make the runtime test fail anyway.
