Serial: bug in 8250.c when handling PCI or other level triggers

[Alan Cox]

The receive_chars function is designed to handle the case where the port
is jammed full on by aborting after 256 characters in one IRQ.
Unfortunately the author of this code forgot that some systems are level
triggered. On these systems the IRQ simply gets invoked again and the
count loop just makes the problem take longer to clear.

In the non level case it appears that a jam could leave the IRQ jammed
forever and ignored - the remaining bytes never appearing.

As far as I can see the code would actually need to clear the interrupt
enable and then restore it on a timer event or similar in order to get
the intended effect.

Could this be connected wiht the massive amount of these messages when I
use minicom on a PC to see another computers serial console?

serial8250: too much work for irq4

I've seen this on different PC-s, PIIX3+K6 and ICH2+Celeron are the
last ones that I certainly remember behaving like this.

If we trigger this, we can assume that the port is dead anyway, or
we're in a situation where the host CPU can not keep up with the
data stream.

If we want to handle this more gracefully as you suggest, we need
to disable the interrupt from the chip entirely, and flag an error
to the TTY layer.

Hmm, possibly, but could you apply this patch and provide the resulting
messages please?  It'll probably cause some character loss when it
decides to dump some debugging.

Not actually true in some cases.

- When your UART has a large FIFO and pretends to be an 8250 you can get
a 256 byte burst triggered by the box sleeping for a moment or the BIOS
SMI crap going to chat to the battery

- On a virtualised system this trap can trigger because the emulations
don't emulate the bit arrival and baud rate.

In both of those cases recovery is viable. For that matter so is
recovery when the user responds to the complaint message by unplugging
the cable, or where a long burst of framing errors hits you from a
misconfiguration.

Possibly the first two just argue for a larger limit ?

In which case the receive_chars() function gobbles up to 255 characters
from the device before relinquishing to the main interrupt loop.  The
main interrupt loop has two exit conditions - no further interrupts
are pending from any device, or we run this loop 256 times.

In the case where further characters are waiting, we will re-run the
receive_chars() function.

Hence, we will check the device up to 256 times and each will potentially
receive 255 characters, which gives about 64K of character reception
before the warning triggers.

Therefore, this scenario is _very_ _very_ unlikely.

Again, only if there's more than about 64K of data waiting.

I don't think so. The bug as such is something I can only see being
triggerable either by a virtual machine or by something like serious
noise on the signal lines (eg put a 10Khz carrier on the carrier detect
line)

We found and patched this bug in one of our products. The patch was to
raise the loop counter to something more appropriate for our hardware.
The condition: the not-to-speedy embedded CPU and all ports in use.
The interrupt handler would hit the loop limit because the combination
of all ports running meant usually there was one port that needed
servicing, upping the loop count by one.

Here is the full dmesg with it, from ICH2. First messages are from 
serial port initialisation and the last ones are from running minicom at 
9600 as thje console for a cisco.

Urm, this is silly.  Lets look at the first instance.

This is the first interrupt we apparantly recieved.  We start with
end =  NULL, l = i->head, and pass_counter starts off at zero (as
can be seen in the num line above.)

                up = list_entry(l, struct uart_8250_port, list);

                iir = serial_in(up, UART_IIR);

The IIR for the device reports 0x01 (IIR_NO_INT set) so no interrupt
was pending, so:

                if (!(iir & UART_IIR_NO_INT)) {
                } else if (end == NULL)
                        end = l;

we set our end marker to this port and move on to the next port.

                l = l->next;

Since we only have one port open on this IRQ, l is equal to l->next
so this has no effect.

                if (l == i->head && pass_counter++ > PASS_LIMIT) {

since l is still equal to i->head, we increment the pass counter.

        } while (l != end);

We set end = l above.  Given the comments above, that means that l
_is_ equal to end, so we should exit this loop.

> 31: jif=fffef262 type=00 num=01 iir=01 lsr=60 => iir=01 lsr=60

However, strangely we don't exit the loop, but we go around for
another go - since we can see num=1 here, which means pass_counter
is now '1'.

In addition, what's weirder is that iir is still saying NO_INT,
yet we seem to have taken a completely different path through
the code since the LSR value is now set.  This is only set in the
other branch of the if statement, inside serial8250_handle_port().

> 32: jif=fffef262 type=00 num=02 iir=01 lsr=60 => iir=01 lsr=60

And we go again... and again...

until we hit the PASS_LIMIT and produce this dump.

The rest of the dumps show a very similar situation.  To me, it
looks like your machine is _not_ doing what the C code is telling
it to do.  Compiler bug maybe?

Ah, a real interrupt for once - a transmit interrupt which we
service, and then...

> 29: jif=fffef2c8 type=00 num=01 iir=c1 lsr=00 => iir=c1 lsr=00

recheck the interrupt status and then exit as we should always
do.  Why this is any different from the previous one I've no
idea... so maybe it can't be a compiler bug...

Unless the compiler is messing up the initialiser for:

        struct list_head *l, *end = NULL;

Could you try placing a:

	BUG_ON(end != NULL);

between:

        spin_lock(&i->lock);

and:

        l = i->head;

in serial8250_interrupt please?

If that doesn't trigger, then I'm all out of ideas.

It did not trigger.

But I might have some more information:

The first bunch of messages did not happen on serial port detection but 
when "discover" ran and opened the serial port.

The second bunch of messages happened when minicom opened the port. I 
then modprobed tulip to see separating lines in dmesg. Then I used cisco 
remote console and no messages appeared. Then I powered down the cisco 
and then quited minicom. This took time and produced another bunch of 
messages.

Thanks for spending the time trying to track this down.

I'm still grasping at straws - it is plainly clear to me from the
debug traces that your machine is _not_ doing what the C code is
asking it to do.

Basically, the characteristics seem to be:

 * if the UART indicates no IRQ on invocation of the interrupt
   handler, we repeatedly loop in the handler and eventually
   hit this "too much work" problem.

 * if the UART indicates IRQ on invocation of the interrupt, and
   subsequently no IRQ, we exit the interrupt handler as per the
   code.

I notice you're using gcc 4.0.3.  Have you tried other compiler
versions?

Are you building the kernel with any additional compiler flags?

Are there any other patches applied to the 8250.c file apart from my
debugging patch?  What's the diff between a vanilla Linus kernel and
the one you built?

If it isn't a compiler bug and there aren't any other patches applied,
I have no idea what to suggest next, apart from your computer seemingly
following a different set of rules to the rest of the universe.  Maybe
you could donate it to some quantum physics lab? 8)

If anyone else has any suggestions, please jump in now.

Will try 3.3.

No.

Clean uptodate -git tree + your patch + BUG_ON

Also have seen this on many earlier kernels that were 100% vanilla.

Both machines having the trouble have kernels that are compiled on this 
specific host and with this specific controller.

Tried 3.3 (Debian 3.3.6). Discover still gets the errors, opening port 
with minicom didn't this time (maybe I did start minicom an power on the 
switch in different order). But when closing minicom, I got the messages 
again (after the AGP messages).

So not much change.

Ok, please apply this patch on top of the previous and re-send the
kernel messages.  This will let us see what's going on with 'l' and

replaced i->heqad with l because i is shadowed by a local variable here, 
now it compiles.

Argh, fek fek fek.  The original debug patch contained some extra code
to try to combat a problem I've been seeing here, which is causing more
complaints from your machine.

Right, discard all the patches I sent previously and use this one.

Thanks.

Can I assume that the bug has disappeared?  Does the patch make it
disappear?

Please notice official linus 2.6.15 tree doesn't have this fix... I've
just installed a virtual machine (qemu-system-i386 with linus 2.6.15 +
plain debian 3r0, console output to xterm via emulated serial console)
and trying to use any curses program (top for example) produces
exactly this type of error.

QEMU_AUDIO_DRV=none \
  nice /home/qemu/bin/qemu \
    -nographic \
    -hda debian-30r0-i386-rootfs.ext2 \
    -kernel bzImage-2.6.15 \
    -append "console=ttyS0,9600n8 lpj=10000 noapic root=/dev/hda"

I'm now recompiling with this lower limit to test...

That's because the patch just adds debugging seems to be sufficient to
cause the bug to disappear.  It isn't a fix.

The only explaination I have at the moment is that it changes the timing
- maybe there's a bug in these UARTs... I don't know at the moment.
What I do know is that Alan's original premise seems wrong.
