  • Rationale:
    Reduces attack surface on kernel devs opening the links for MITM
    as HTTPS traffic is much harder to manipulate.

    Deterministic algorithm:
    For each file:
    If not .svg:
    For each line:
    If doesn't contain `\bxmlns\b`:
    For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
    If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
    If both the HTTP and HTTPS versions
    return 200 OK and serve the same content:
    Replace HTTP with HTTPS.

  • Replace the existing /* fall through */ comments and its variants with
    the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
    fall-through markings when it is the case.

  • All watchdog drivers implement the same set of ioctl commands, and
    fortunately all of them are compatible between 32-bit and 64-bit
    architectures.

    Modern drivers always go through drivers/watchdog/wdt.c as an abstraction
    layer, but older ones implement their own file_operations on a character
    device for this.

    Move the handling from fs/compat_ioctl.c into the individual drivers.

    Note that most of the legacy drivers will never be used on 64-bit
    hardware, because they are for an old 32-bit SoC implementation, but
    doing them all at once is safer than trying to guess which ones do
    or do not need the compat_ioctl handling.

  • Using scripts/coccinelle/api/stream_open.cocci added in 10dce8af3422
    ("fs: stream_open - opener for stream-like files so that read and write
    can run simultaneously without deadlock"), search and convert to
    stream_open all in-kernel nonseekable_open users for which read and
    write actually do not depend on ppos and where there is no other methods
    in file_operations which assume @offset access.

    I've verified each generated change manually - that it is correct to convert -
    and each other nonseekable_open instance left - that it is either not correct
    to convert there, or that it is not converted due to current stream_open.cocci
    limitations. The script also does not convert files that should be valid to
    convert, but that currently have .llseek = noop_llseek or generic_file_llseek
    for unknown reason despite file being opened with nonseekable_open (e.g.
    drivers/input/mousedev.c)

    Among cases converted 14 were potentially vulnerable to read vs write deadlock
    (see details in 10dce8af3422):

    and the rest were just safe to convert to stream_open because their read and
    write do not use ppos at all and corresponding file_operations do not
    have methods that assume @offset file access(*):

    (*) This second group also contains cases with read/write deadlocks that
    stream_open.cocci don't yet detect, but which are still valid to convert to
    stream_open since ppos is not used. For example drivers/pci/switch/switchtec.c
    calls wait_for_completion_interruptible() in its .read, but stream_open.cocci
    currently detects only "wait_event*" as blocking.

  • I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR)
    and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements.

    Either the device is enumerated and the driver already has a module
    alias (e.g. PCI, USB etc.) that will get the right driver loaded
    automatically.

    Or the device is not enumerated and loading its driver will lead to
    more or less intrusive hardware poking. Such hardware poking should be
    limited to a bare minimum, so the user should really decide which
    drivers should be tried and in what order. Trying them all in
    arbitrary order can't do any good.

    On top of that, loading that many drivers at once bloats the kernel
    log. Also many drivers will stay loaded afterward, bloating the output
    of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets
    loaded as a dependency) can't even be unloaded!

    If defining char-major-10-130 is needed then it should happen in
    user-space.

  • At present the module does not unset the NO_REBOOT bit upon shutdown, this
    causes the BIOS to fail the POST once and reset. During the next boot it
    displays the following error message:

    ***** Warning: System BOOT Fail *****
    Your system last boot fail or POST interrupted.
    Please enter setup to load default and reboot again.
    Press F1 to continue, DEL to enter SETUP

    With this patch the NO_REBOOT flag will be unset on shutdown and thus stop
    this failure from occurring.

    Tested on 'ASUS P5N32-E SLI with BIOS revision 1801' and
    'ASUS P5N32-E SLI PLUS with BIOS revision 1502'.

  • Fix section mismatch warning:
    Mark the called nv_tco_getdevice() as __devinit, just like its caller.

    WARNING: drivers/watchdog/nv_tco.o(.devinit.text+0x16): Section mismatch in reference from the function nv_tco_init() to the function .init.text:nv_tco_getdevice()
    The function __devinit nv_tco_init() references
    a function __init nv_tco_getdevice().
    If nv_tco_getdevice is only used by nv_tco_init then
    annotate nv_tco_getdevice with a matching annotation.

  • This driver adds support for /dev/watchdog for boards using either the MCP51 or
    MCP55 chipsets. These are also known as the nForce 430 and nForce 550. This
    driver is likely to work on other chipsets as well, though those are the only
    two that have been tested.
