  • 0f4bd46ec   kmsg_dump: Dump on crash_kexec as well ... Browse Code »

    crash_kexec gets called before kmsg_dump(KMSG_DUMP_OOPS) if
    panic_on_oops is set, so the kernel log buffer is not stored
    for this case.

    This patch adds a KMSG_DUMP_KEXEC dump type which gets called
    when crash_kexec() is invoked. To avoid getting double dumps,
    the old KMSG_DUMP_PANIC is moved below crash_kexec(). The
    mtdoops driver is modified to handle KMSG_DUMP_KEXEC in the
    same way as a panic.

    kmsg_dump() fails to build when CONFIG_PRINTK=n; provide stubs
    for the kmsg_dump*() functions when CONFIG_PRINTK=n.

    kernel/printk.c: In function 'kmsg_dump':
    kernel/printk.c:1501: error: 'log_buf_len' undeclared (first use in this function)
    kernel/printk.c:1502: error: 'logged_chars' undeclared (first use in this function)
    kernel/printk.c:1506: error: 'log_buf' undeclared (first use in this function)

  • 456b565cc   core: Add kernel message dumper to call on oopses and panics ... Browse Code »

    The core functionality is implemented as per Linus suggestion from

    http://lists.infradead.org/pipermail/linux-mtd/2009-October/027620.html

    (with the kmsg_dump implementation by Linus). A struct kmsg_dumper has
    been added which contains a callback to dump the kernel log buffers on
    crashes. The kmsg_dump function gets called from oops_exit() and panic()
    and invokes this callbacks with the crash reason.
