  • 2aa362c49   coredump: extend core dump note section to contain file names of mapped files ... Browse Code »

    This note has the following format:

    long count -- how many files are mapped
    long page_size -- units for file_ofs
    array of [COUNT] elements of
    long start
    long end
    long file_ofs
    followed by COUNT filenames in ASCII: "FILE1" NUL "FILE2" NUL...

  • 49ae4d4b1   coredump: add a new elf note with siginfo of the signal ... Browse Code »

    Existing PRSTATUS note contains only si_signo, si_code, si_errno fields
    from the siginfo of the signal which caused core to be dumped.

    There are tools which try to analyze crashes for possible security
    implications, and they want to use, among other data, si_addr field from
    the SIGSEGV.

    This patch adds a new elf note, NT_SIGINFO, which contains the complete
    siginfo_t of the signal which killed the process.

  • 1fcccbac8   elf coredump: replace ELF_CORE_EXTRA_* macros by functions ... Browse Code »

    elf_core_dump() and elf_fdpic_core_dump() use #ifdef and the corresponding
    macro for hiding _multiline_ logics in functions. This patch removes
    #ifdef and replaces ELF_CORE_EXTRA_* by corresponding functions. For
    architectures not implemeonting ELF_CORE_EXTRA_*, we use weak functions in
    order to reduce a range of modification.

    This cleanup is for my next patches, but I think this cleanup itself is
    worth doing regardless of my firnal purpose.

  • 2f79e48ae   x86: compat_binfmt_elf ... Browse Code »

    This adds fs/compat_binfmt_elf.c, a wrapper around fs/binfmt_elf.c for
    32-bit ELF support on 64-bit kernels. It can replace all the hand-rolled
    versions of this that each 32/64 arch has, which are all about the same.

    To use this, an arch's asm/elf.h has to define at least a few compat_*
    macros that parallel the various macros that fs/binfmt_elf.c uses for
    native support.

    There is no attempt to deal with compat macros for the core dump format
    support. To use this file, the arch has to define compat_gregset_t for
    linux/elfcore-compat.h and #define CORE_DUMP_USE_REGSET. The 32-bit
    compatible formats should come automatically from task_user_regset_view
    called on a 32-bit task.
