Kernel is 2.6.16.16 with my patches, including a patch to the
e1000.  I also rebuilt a fresh kernel with only the attached
send-to-self patch.  I see the hang, but there was no OOM messages,
probably because the machine was freshly rebooted and had plenty
of buffers available.  I will try to reproduce this with some other
NICs next...

I am running 2 TCP connections between two ports of a pro/1000 NIC with
fiber interfaces.  Both connections are trying to send 200Mbps in both
directions.  Each write to the socket is 5000 bytes.  MTU is 1500.

After maybe 10 seconds, I see out-of-memory errors on the console and
then the connections hang and send no more traffic.  However, the
NICs are still showing ~215kpps.  According to ethereal, these are
duplicate acks.

107215 packets dropped

Stopping the TCP connection does not appear to immediately fix the problem:
The connections are in the FIN_WAIT1 state and the dup acks continue to flow.

ifdown/ifup after stopping the connections seems to clear the problem.

I saw no more OOM messages with TOE disabled, but the connection still
hangs.


The OOM related console messages are attached.

The problem also happens when no OOM messages are printed, but it runs slightly
longer (maybe 15-20 seconds).

I suspect that a dropped packet or packets is somehow the problem.


Thanks,
Ben

The same problem happens with a single TCP connection between two
copper 10/100/1000 intel ports on the FC2 dual-xeon 32-bit machine.


I tried a dual-core AMD system running 64-bit kernel and FC5.  This kernel
is running my complete set of patches (against 2.6.16.16).

I can reproduce with Intel pro/1000 on this dual-core system when I up the rate to 400Mbps
and do 50,000 byte writes (can only get 125Mbps with 5000 byte writes on
this system, and it ran at that speed for several minutes w/out problem.)

I can also reproduce when using the tg3 adapters, but the tg3 can only run at about
220Mbps, even with the larger write size.  This slower speed could be because of bus
issues or the VLAN I used for one end of the connection.  I could not see this problem with tg3 untill
I yanked the cable a few times and then ran the connection through my network
emulator (which will cause a bit of latency and some dropped packets).  The tethereal
output looks slightly different, but I think this is just because it is a different
version from the older FC2 system from my previous email.

Well, it's reproducible with only the send-to-self patch, so I figured it wouldn't
help to show the e1000 patches.  Also, it is reproducible on tg3, so it is not
e1000 specific, though it is slightly easier to trigger on e1000
for some reason (possibly higher throughput or something specific
about my configuration.)

I haven't seen this problem on 2.6.13, so I'm now starting a manual bisect
to see if I can narrow down where the problem appeared.

Turns out, I can reproduce it in 2.6.13, and 2.6.9.  I haven't tried anything
older.

I also tried to reproduce it using a simpler traffic generation tool, but could
not reproduce the problem with it.  That points to something wierd that my application
is doing, but I can't imagine what user-space could do to screw up a TCP connection
like this.

In all cases, there is a lot of data in the send-queue, but for whatever
reason, the connection will not make progress.  To user-space, it appears
that poll returns neither readable nor writable for the sockets.

I notice that if I increase the send-buffer-size while the connection is
in the hung state, my app will quickly fill the larger send buffer, but
still receives nothing new.

Starting a new connection on the same interfaces works for a few seconds
and then hangs as well, so the NICs can pass traffic.

Here is output from /proc/net/tcp and netstat from the 2.6.16.16 kernel.

Ok, I think I found the problem.  It appears to be at least partially
self-inflicted.  I was modifying the kernel buffer settings via /proc/*
to improve performance.  I noticed that when I used kernel-defaults,
the TCP connection hangs stopped (and ran ~20% slower).  My personal opinion
is that this is still a bug somewhere in TCP, but at least I have a work-around.

Since these settings appear somewhat delicate, it might be nice if
the kernel could warn about configurations that could cause TCP deadlocks
and such.

My old settings that exhibitted the problem were:

my $netdev_max_backlog = 5000;
my $wmem_max = 4096000;
my $wmem_default = 128000;
my $rmem_max = 8096000;
my $rmem_default = 128000;

my $tcp_rmem_min     = 4096;
my $tcp_rmem_default = 256000;
my $tcp_rmem_max     = 30000000;

my $tcp_wmem_min     = 4096;
my $tcp_wmem_default = 256000;
my $tcp_wmem_max     = 30000000;

my $tcp_mem_lo       = 20000000;
my $tcp_mem_pressure = 30000000;
my $tcp_mem_high     = 60000000;

The new settings that appear to work around the TCP connection hang,
and still give decent performance are below.  Documentation being thin,
I used the suggested values in Documentation/networking/ixgb.txt as
hints:

my $netdev_max_backlog = 30000;
my $wmem_max = 524287;
my $wmem_default = 128000;
my $rmem_max = 524287;
my $rmem_default = 128000;

my $tcp_rmem_min     = 4096;
my $tcp_rmem_default = 256000;
my $tcp_rmem_max     = 5000000;

my $tcp_wmem_min     = 4096;
my $tcp_wmem_default = 256000;
my $tcp_wmem_max     = 5000000;

my $tcp_mem_lo       = 10000000;
my $tcp_mem_pressure = 20000000;
my $tcp_mem_high     = 30000000;

If you set bogus values, you can end up consuming all the memory on your system.

There is little or no range checking on most all sysctl values. Whether or
not that is a good thing is debatable.

This only matters for non-NAPI devices.

Receiver auto-tuning makes setting this unnecessary
in most cases.

That's too big with current auto-tuning.

Settings don't belong in this Documentation file because it a general
thing not specific to that hardware.

I still had some sort of memory..ie I could run other applications and could
start a second TCP connection on the same interface.  It is true that you can
truly OOM systems with bad settings here, but my machine has 2GB of RAM, and
I think my setting were low enough that it should not have run out.  It also
had enough memory left to spam the duplicate TCP acks at around 200kpps in
both directions!  Manually over-riding the write buffer size had little or
no effect:  It would still hang.

The file was describing how to tune for good performance using their
NICs.

At least most of the TCP settings are described in the networking/ip-sysctl.txt
file, but I could find nothing on the core.rmem_max setting, except in examples
in the 10Gbe NIC help texts.

It would be nice to either have the core.* values described in the
ip-sysctl.txt file, or perhaps add a new file.

There are tuning tips all over the web too...often quite badly
outdated it seems.  Might be a good thing to add to the linux-net wiki.

I'd give it a try, but obviously my info is suspect! :P

We specifically calculate the packet size here to avoid a 2-page
allocation, yet we still do.  This is the bug.

[NET]: Fix SKB_MAX_ORDER calculation

The calculation in SKB_MAX_ORDER is incorrect in that it can cause
an overflow across a page boundary which is what it's meant to prevent.
In particular, the header length (X) should not be lumped together with
skb_shared_info.  The latter needs to be aligned properly while the header
has no choice but to sit in front of wherever the payload is.

Therefore the correct calculation is to take away the aligned size of
skb_shared_info, and then subtract the header length.  The resulting
quantity L satisfies the following inequality:

	SKB_DATA_ALIGN(L + X) + sizeof(struct skb_shared_info) <= PAGE_SIZE

This is the quantity used by alloc_skb to do the actual allocation.

While we're at it, there is no need to round up the header size in
sk_stream_alloc_pskb.  The only thing this achieves is to make the
data payload cache-aligned.  However, the data payload is just a
byte stream with no alignment requirements.  So we should take away
the rounding.
