  • commit 64ce4c2f (time: Clean up warp_clock()) breaks the timezone
    update in a very subtle way. To avoid the direct access to timekeeping
    internals it adds the timezone delta to the current time with
    timespec_add_safe(). This works nicely when the timezone delta is > 0.
    If timezone delta is < 0 then the wrap check in timespec_add_safe()
    triggers and timespec_add_safe() returns TIME_MAX and screws up
    timekeeping completely.

    The comment above timespec_add_safe() says:
    It's assumed that both values are valid (>= 0)

    Add the timezone seconds adjustment directly.

  • The kernel debugger can operate well before mm_init(), but the x86
    hardware breakpoint code which uses the perf api requires that the
    kernel allocators are initialized.

    This means the kernel debug core needs to provide an optional arch
    specific call back to allow the initialization functions to run after
    the kernel has been further initialized.

    The kdb shell already had a similar restriction with an early
    initialization and late initialization. The kdb_init() was moved into
    the debug core's version of the late init which is called
    dbg_late_init();

  • Some kgdb I/O modules require the ability to create a breakpoint
    tasklet, such as kgdboc and external modules such as kgdboe. The
    breakpoint tasklet is used as an asynchronous entry point into the
    debugger which will have a different function scope than the current
    execution path where it might not be safe to have an inline
    breakpoint. This is true of some of the kgdb I/O drivers which share
    code with kgdb and rest of the kernel users.

  • The only way the debugger can handle a trap in inside rcu_lock,
    notify_die, or atomic_notifier_call_chain without a triple fault is
    to have a low level "first opportunity handler" in the int3 exception
    handler.

    Generally this will be something the vast majority of folks will not
    need, but for those who need it, it is added as a kernel .config
    option called KGDB_LOW_LEVEL_TRAP.

  • This patch adds in the kdb PS/2 keyboard driver. This was mostly a
    direct port from the original kdb where I cleaned up the code against
    checkpatch.pl and added the glue to stitch it into kgdb.

    This patch also enables early kdb debug via kgdbwait and the keyboard.

    All the access to configure kdb using either a serial console or the
    keyboard is done via kgdboc.

    If you want to use only the keyboard and want to break in early you
    would add to your kernel command arguments:

    kgdboc=kbd kgdbwait

    If you wanted serial and or the keyboard access you could use:

    kgdboc=kbd,ttyS0

    You can also configure kgdboc as a kernel module or at run time with
    the sysfs where you can activate and deactivate kgdb.

    Turn it on:
    echo kbd,ttyS0 > /sys/module/kgdboc/parameters/kgdboc

    Turn it off:
    echo "" > /sys/module/kgdboc/parameters/kgdboc

  • One of the driving forces behind integrating another front end (kdb)
    to the debug core is to allow front end commands to be accessible via
    gdb's monitor command. It is true that you could write gdb macros to
    get certain data, but you may want to just use gdb to access the
    commands that are available in the kdb front end.

    This patch implements the Rcmd gdb stub packet. In gdb you access
    this with the "monitor" command. For instance you could type "monitor
    help", "monitor lsmod" or "monitor ps A" etc...

    There is no error checking or command restrictions on what you can and
    cannot access at this point. Doing something like trying to set
    breakpoints with the monitor command is going to cause nothing but
    problems. Perhaps in the future only the commands that are actually
    known to work with the gdb monitor command will be available.

  • The design of the kdb shell requires that every device that can
    provide input to kdb have a polling routine that exits immediately if
    there is no character available. This is required in order to get the
    page scrolling mechanism working.

    Changing the kernel debugger I/O API to require all polling character
    routines to exit immediately if there is no data allows the kernel
    debugger to process multiple input channels.

    NO_POLL_CHAR will be the return code to the polling routine when ever
    there is no character available.

  • These are the minimum changes to the kgdb core in order to enable an
    API to connect a new front end (kdb) to the debug core.

    This patch introduces the dbg_kdb_mode variable controls where the
    user level I/O is routed. It will be routed to the gdbstub (kgdb) or
    to the kdb front end which is a simple shell available over the kgdboc
    connection.

    You can switch back and forth between kdb or the gdb stub mode of
    operation dynamically. From gdb stub mode you can blindly type
    "$3#33", or from the kdb mode you can enter "kgdb" to switch to the
    gdb stub.

    The logic in the debug core depends on kdb to look for the typical gdb
    connection sequences and return immediately with KGDB_PASS_EVENT if a
    gdb serial command sequence is detected. That should allow a
    reasonably seamless transition between kdb -> gdb without leaving the
    kernel exception state. The two gdb serial queries that kdb is
    responsible for detecting are the "?" and "qSupported" packets.

  • This patch contains only the kdb core. Because the change set was
    large, it was split. The next patch in the series includes the
    instrumentation into the core kernel which are mainly helper functions
    for kdb.

    This work is directly derived from kdb v4.4 found at:

    ftp://oss.sgi.com/projects/kdb/download/v4.4/

    The kdb internals have been re-organized to make them mostly platform
    independent and to connect everything to the debug core which is used by
    gdbstub (which has long been known as kgdb).

    The original version of kdb was 58,000 lines worth of changes to
    support x86. From that implementation only the kdb shell, and basic
    commands for memory access, runcontrol, lsmod, and dmesg where carried
    forward.

    This is a generic implementation which aims to cover all the current
    architectures using the kgdb core: ppc, arm, x86, mips, sparc, sh and
    blackfin. More archictectures can be added by implementing the
    architecture specific kgdb functions.

  • New wait_event_interruptible{,_exclusive}_locked{,_irq} macros added.
    They work just like versions without _locked* suffix but require the
    wait queue's lock to be held. Also __wake_up_locked() is now exported
    as to pair it with the above macros.

    The use case of this new facility is when one uses wait queue's lock
    to protect a data structure. This may be advantageous if the
    structure needs to be protected by a spinlock anyway. In particular,
    with additional spinlock the following code has to be used to wait
    for a condition:

    spin_lock(&data.lock);
    ...
    for (ret = 0; !ret && !(condition); ) {
    spin_unlock(&data.lock);
    ret = wait_event_interruptible(data.wqh, (condition));
    spin_lock(&data.lock);
    }
    ...
    spin_unlock(&data.lock);

    This looks bizarre plus wait_event_interruptible() locks the wait
    queue's lock anyway so there is a unlock+lock sequence where it could
    be avoided.

    To avoid those problems and benefit from wait queue's lock, a code
    similar to the following should be used:

    /* Waiting */
    spin_lock(&data.wqh.lock);
    ...
    ret = wait_event_interruptible_locked(data.wqh, (condition));
    ...
    spin_unlock(&data.wqh.lock);

    /* Waiting exclusively */
    spin_lock(&data.whq.lock);
    ...
    ret = wait_event_interruptible_exclusive_locked(data.whq, (condition));
    ...
    spin_unlock(&data.whq.lock);

    /* Waking up */
    spin_lock(&data.wqh.lock);
    ...
    wake_up_locked(&data.wqh);
    ...
    spin_unlock(&data.wqh.lock);

    When spin_lock_irq() is used matching versions of macros need to be
    used (*_locked_irq()).
