    What the thing really wants is some kind of indication of state,
    without having to bloat up the scatterlist structure.

    I believe that we have enough of a limited set of accessors to
    sg->page that we can more aggressively encode things in the lower
    bits.

    I'm thinking of encoding the low two bits of sg->page as
    follows:

    1) bits == 0

    then the SG list is linear and sg_next() is sg++

    2) bits == 1

    the nest SG is an indirect chunk, sg_next() is
    therefore something like:

    next = *((struct scatterlist **)(sg + 1));

    3) bits == 2

    this is the last entry in the scatterlist, sg_next() is NULL

    So for the cases of ARCH_HAS_SG_CHAIN not being set (ie. back
    compatible), we can do no bit encoding in page->flags and just do
    sg_next() == sg++, as is done now.

    When doing SG chaining, in each non-linear chunk we have to allocate
    one more pointer past the end of the scatterlist array (instead of a
    full extra scatterlist entry for the indirect pointer encode). Next,
    all sg->page accesses have to be guarded to clear the state bits
    out first.

    I don't know, maybe it would work, and would make the loop termination
    issues easier to handle properly.

  2. Re: [bug] ata subsystem related crash with latest -git

    On a related hardware note:

    FWIW, most ATA controllers have scatter/gather tables that terminate
    themselves by a bit in the final s/g entry. The 90% case needs to know
    the last scatterlist entry, at the end of the s/g walk.

    So however this all gets worked out, please make sure not to unduly
    punish libata controllers with an expensive sg_last() inside a loop, or
    something like that.

    Yes, that sounds sane.

    Although I also wonder whether we want one global per-arch
    ARCH_HAS_SG_CHAIN, or perhaps have something more dynamic, which allows a
    per-SG-list choice (which in turn would require some kind of "head" entry
    that is passed into sg_next(), and in general descibes the SG list)

    It's there because the DMA mapping support code for a platform has to
    be converted to handle these chains and audited to make sure the
    conversion is right. Some platforms, such as sparc64, took a lot of
    work to get right :-)

    Once that macro is set, the block device driver has to support it too,
    and there are knobs all the way down to the scsi host driver to
    indicate this.

    The idea is that all of this mess gets deleted in the end, it was
    meant to be a safe transition scheme.

    It would be good to have something soon-ish.
    This "dead at boot time" issue is impacting the general ability to test
    patches against latest -git in time for the current merge window.

    Oh.. so this bug is supposed to only bite with DEBUG_PAGEALLOC=y ??

    Then something else is broken, perhaps. I just saw a long traceback
    scroll off the top of the screen, with lots of bio_* functions in the list
    and assumed it was the same bug.

    Mmm.. I'll get out the camera and try it again now..

    In the meantime, does the patch I sent out help people? I'd like to get
    feedback, but I'm a lazy bum, and don't use DEBUG_PAGEALLOC myself, so I

    I'm currently bisecting on two machines (sata_mv and sata_nv). sata_mv
    suddenly started spewing errors in recent kernels, but kernels from ~48
    hours ago are just fine. AMD64 sata_nv machine will simply lock up if I
    push it too hard. Again, reproducible, and kernels from ~48 hours ago
    are fine.

    AHCI machine so far seems fine (kernel ~24 hours ago), storage-wise, but
    the hda_intel audio decided to stop working

    I'm quite happy to test patches, but I never run with DEBUG_PAGEALLOC so
    that shouldn't be causing the problems here.

    Okay, mine is dying with EIP at blk_rq_map_sg+0xcb/0x160.

    Screen photo is at http://rtr.ca/recent/2.6.23-git12-crash.jpg,
    but the top was cut off (isn't there a new config option or patch
    to do double-columns or scrollback or something ???.

    Yeah, this particular one really should only bite you with
    DEBUG_PAGEALLOC.

    The SG code potentially _derefences_ a field past the end of the SG array,
    but it should be a read, and the result should never be used (it's used to
    calculate the pointer to past the end of the queue, so if it's used,
    there's another bug lurking).

    Please do. I wouldn't be surprised if it's also related to the SG changes,
    but I don't think it's the exact particular bug that Ingo saw.

    No.. it's a pretty ordinary ata_piix machine, with no serial ports either.

    Ok, I think your picture cut off the last hex digits on the right, but
    what I can make out of the disassembly, I have to admit that it looks
    very much like it might be exactly the same thing Ingo was seeing.

    The disassembly is a bit scrambled, but the particular instruction that
    oopses for you is

    mov 0x10(%ebx),%eax

    and the instructions around it do seem to bear some similarity to the
    whole "sg_next()" thing, ie I see a

    test $0x1,%al

    and a

    lea 0x10(%ebx),%eax

    around there too.

    If you cut down the number of entries printed for the call trace (which
    involves editing the source code, no nice config options, I'm afraid), you
    could get the rest of it..

    That could explain it: if the SG allocation is simply too small, the
    scatter-gather code will run off the end of the SG list, and encounter
    random uninitialized entries, and if any of those have the low bit set,
    they will be considered to be "link" entries, and the SG list goes wild.

    That SG code is really pretty fragile. I don't see it *ever* checking that
    the SG allocation is large enough when it fills it in. And these things
    take the sizes from different places (ie "cmd->use_sg" bs
    "req->nr_phys_segments" vs God knows what else..)

    I tried the fancy "boot_delay=nnn" feature, but that doesn't slow down
    the tracebacks at all. So I hardcoded some mdelay(1000) lines into
    the traceback code, and here's the top part of the oops now:

    Your patch from this posting http://lkml.org/lkml/2007/10/17/285
    does not seem to make much difference here.

    It still crashes at exactly the same place.

    However, Jens's patch from that same thread:

    ...allowed me to boot and post this followup message from -git12

    Jeff: try that one.

    That's already in my upstream kernel, here. commits
    ba951841ceb7fa5b06ad48caa5270cc2ae17941e and
    a3bec5c5aea0da263111c4d8f8eabc1f8560d7bf.

    sata_mv and sata_nv still reliably poop themselves here, whereas its
    rock solid with 2.6.23.1. Sounds like different issues from yours, as I
    see a stream of SATA errors on the bad kernels, errors which are often a
    symptom of something whacked in the DMA engine (misprogramming causes
    the silicon to generate bogus FIS's, which the device then chokes on)
