3.4.x regression: rtl8169: frequent resets

3.4.x regression: rtl8169: frequent resets

[Nix]

I recently upgraded from 3.3.x to 3.4.4, and am now experiencing
networking problems with my desktop box's r8169 card. The symptoms are
that all traffic ceases for five to ten seconds, then the card appears
to reset and everything is back to normal -- until it happens again. It
can happen quite a lot:

[242614.238212] r8169 0000:06:00.0: fastnet: link up

Sometimes, it takes so long to reset that the slowpath warning kicks in,
but it's not too useful:

That was the first instance I saw, but they're getting more and more
frequent: I've had five in the last half hour.

I'm using the tuxonice patches, but I haven't suspended yet so I don't
think we need to suspect that for now. (I'm happy to reboot into a
tuxoniceless kernel and see if this keeps happening: unfortunately, it
does appear that they don't start happening at all until the machine has
been up for a day or so.)

I can try, but there's been a *lot* of code motion since then, 'git
revert' fails hilariously (trying to patch obviously the wrong places):
I'll have to do it by hand.

I'll try that tomorrow. (But, as before, it might be several days before
we know anything one way or the other. Assuming I can revert it without
fouling something else up.)

I'm not using BQL (yet, anyway).

I note that at some time (after the first reset?), my MTU either flipped
back to 1500, from its initial jumbo default, or simply refused to go
jumbo in the first place. I bring it up like so:

ip link set fastnet up multicast on txqueuelen 100 mtu 7200
ip addr add local 192.168.16.20/24 broadcast 192.168.16.255 dev fastnet

but its MTU is now shown as 1500 :( so at some point either jumbo frames
have stopped working or the reset is flipping them off. (It used to
work, with a warning yelling about how terribly dangerous jumbo frames
were because any attacker on the local subnet could subvert my machine.
Any attacker on the local subnet will be sitting in my lap and/or will
have root on the NFS server from which this machine is getting all its
data, so I don't care one jot about that. This may be because rx
checksumming is turned on by default, and as of last year that forces
jumbo frames off: I've turned that off and will see if jumbo frames
start working next time I bring the interface up. I *thought* my local
network was awful slow lately...)

There is a single line reject in rtl8169_start_xmit. Other than that it
should patch -p1 -R fine.

This chipset is not supposed to be pushed beyond 6128 bytes.

... and indeed it does. Weird, why does git revert fail so badly when
patch and git apply are both happy?!

I'll reboot into this kernel tomorrow, and report back in a few days (or
sooner if it goes wrong).

Interesting. It's always worked flawlessly at 7200 for me before, until,
uh, last year when it stopped working and I never noticed (in fact
a 7200-byte MTU was how the machine was shipped to me :) ).

I guess I'll knock it down to 6128 then, less than 1000 bytes isn't
going to ruin performance by any means...

... aand that works. thanks! (Let's see if the link stuttering continues. I
expect it will, though it's been three hours since the last stutter...)

I received the same oops from a 3.4.4 user with these onboard network 
cards:

r8169 0000:04:00.0: eth0: RTL8168d/8111d at 0xffffc90000c72000, 00:24:1d:72:7c:75, XID 081000c0 IRQ 44
r8169 0000:05:00.0: eth1: RTL8168d/8111d at 0xffffc90000c70000, 00:24:1d:72:7c:77, XID 081000c0 IRQ 45

Reverting 036dafa28da1e2565a8529de2ae663c37b7a0060 (Nix, trivial 
backport to 3.4.4 attached) did improve the situation, no oops in 21
hours uptime so far (while it usually shows up within about an hour).
Unfortunately his oops report was cut brief, so I've asked him to try 
reproducing it with an unpatched kernel again, to collect a full dmesg
(the test is still going on, past the one hour mark, but the oops 
hasn't triggered yet). I'll report back, as soon as I get confirmation 
and a full dmesg.

Pedant point: it's not an oops, just a slowpath warning.

Interesting. I wonder why it took two days to show up for me. It's not
like I'm a very light network user or anything, there are easily 300
packets per second in each direction on this interface every second of
the day (and often much more).

r8169 0000:04:00.0: eth0: RTL8168d/8111d at 0xffffc90000c72000, 00:24:1d:72:7c:75, XID 081000c0 IRQ 44
r8169 0000:05:00.0: eth1: RTL8168d/8111d at 0xffffc90000c70000, 00:24:1d:72:7c:77, XID 081000c0 IRQ 45

Kernel 3.4.4 with 036dafa28da1e2565a8529de2ae663c37b7a0060 (r8169: add 
byte queue limit support) reverted is now running just about 60 hours 
on the afformentioned hardware. No traces of "NETDEV WATCHDOG: eth0 
(r8169): transmit queue 0 timed out" so far, while it usually triggers 
within an hour (5 hours at most) with plain 3.4.4 on that system.
