  • edea13858   uml: tidy kern_util.h ... Browse Code »

    Tidy kern_util.h. It turns out that most of the function declarations
    aren't used, so they can go away. os.h no longer includes
    kern_util.h, so files which got it through os.h now need to include it
    directly. A number of other files never needed it, so these includes
    are deleted.

    The structure which was used to pass signal handlers from the kernel
    side to the userspace side is gone. Instead, the handlers are
    declared here, and used directly from libc code. This allows
    arch/um/os-Linux/trap.c to be deleted, with its remnants being moved
    to arch/um/os-Linux/skas/trap.c.

    arch/um/os-Linux/tty.c had its inclusions changed, and it needed some
    style attention, so it got tidied.

  • 4dbed85a3   uml: stop gdb from deleting breakpoints when running UML ... Browse Code »

    Sometimes when UML is debugged gdb miss breakpoints.

    When process traced by gdb do fork, debugger remove breakpoints from
    child address space. There is possibility to trace more than one fork,
    but this not work with UML, I guess (only guess) there is a deadlock -
    gdb waits for UML and UML waits for gdb.

    When clone() is called with SIGCHLD and CLONE_VM flags, gdb see this
    as PTRACE_EVENT_FORK not as PTRACE_EVENT_CLONE and remove breakpoints
    from child and at the same time from traced process, because either
    have the same address space.

    Maybe it is possible to do fix in gdb, but I'm not sure if there is
    easy way to find out if traced and child processes share memory. So I
    do fix for UML, it simply do not call clone() with both SIGCHLD and
    CLONE_VM flags together. Additionally __WALL flag is used for
    waitpid() to assure not miss clone and normal process events.

  • 89df6bfc0   uml: DEBUG_SHIRQ fixes ... Browse Code »

    DEBUG_SHIRQ generates spurious interrupts, triggering handlers such as
    mconsole_interrupt() or line_interrupt(). They expect data to be available to
    be read from their sockets/pipes, but in the case of spurious interrupts, the
    host didn't actually send anything, so UML hangs in read() and friends.
    Setting those fd's as O_NONBLOCK makes DEBUG_SHIRQ-enabled UML kernels boot
    and run correctly.

    user_util.h isn't needed any more, so delete it and remove all includes of it.

  • 56bd194bb   uml: driver formatting fixes ... Browse Code »

    Fix a bunch of formatting violations in the drivers:
    return(n) -> return n
    whitespace fixes
    emacs formatting comment removal
    breaking if(foo) return(n) into two lines

    There are also a couple of errno use bugs:
    using errno in a printk when the failure put errno into a local variable
    saving errno after a printk, which can change it

  • 91acb21f0   [PATCH] uml: revert block driver use of host AIO ... Browse Code »

    The patch to use host AIO support that I submitted early after 2.6.13 exposed
    some problems in the block driver. I have fixes for these, but am not
    comfortable putting them into 2.6.14 at this late date. So, this patch reverts
    the use of host AIO.

    I will resubmit the original patch, plus fixes to the driver after 2.6.14
    in order to get a reasonable amount of testing before they're exposed to
    the general public.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
