Hi,
I don't want this to get lost around the Christmas break, so I'm just
resending it. I'm still seeing the same behaviour as before.
From above:

This definitely doesn't happen, at least according to 'ip link show |
grep PROMISC'.

* e1000e interface hang on 82574L
From: Chris Boot @ 2011-12-27 22:01 UTC (permalink / raw)
To: netdev, lkml
Hi folks,
Another networking issue I've run into, this time with e1000e (Intel
Corporation 82574L Gigabit). My new VM cluster appears to drop a NIC -
the port stops responding within Linux and shows the link as being down
with ethtool. My ISP says 'Ports running Half Duplex or reduced speed'
on the port.
When the port stops working I see this in dmesg:

To try to regain connectivity I bring down the bond and the interface

I too am experiencing problems with the e1000e. It takes hours to happen,
sometimes days, under a sustained, heavy load (10 iperfs, 1 netperf RR, ping)
while :
do
for i in `seq 1 10`
do
iperf -w254k -t 60 -c MY_SERVER &
done
netperf -H MY_SERVER -t TCP_RR &
wait
sleep2
done
but eventually...
ifconfig will show the e1000e receiving packets, but none will be
transmitted. I kill off the qdisc
(tc del dev eth0 root) and sometimes it comes back (so I was assuming
it was a problem with qfq) - but
this morning I managed to get a full on kernel panic from it and
scribble it down.
This is with net-next as of c5e1fd8ccae09f574d6f978c90c2b968ee29030c -
but I have
been experiencing lockups since I started fiddling with BQL last
month. That said,
I wouldn't consider my environment terribly normal as I'm running with
no tso, no
gso, tx rings of 64, at 100Mbit, BQL's limit at 4500 bytes, and the QFQ qdisc,
and I was willing to write it off
to being too early to jump on net-next until now.
The super duper new fair QFQ based shaping script I've been testing is at:
https://github.com/dtaht/deBloat/blob/master/src/staqfq.lua

Almost every other network driver had memory mapped register.
The problem is volatile is that the compiler is stupid and wrong.
Using explicit barriers is preferred and ensures correct and fast
code.

I am somewhat new to driver development, so I do not know all the tricks of
the trade just yet. Do you have references to doing explicit barriers that
I can look at? Might be worth trying on the RTC driver I have to get the
hang of them.

Start by reading volatile considered harmful and memory barriers in kernel
Documentation directory. Paul does a better job of explaining it than

* [PATCH] tcp: detect loss above high_seq in recovery
From: Yuchung Cheng @ 2011-12-28 0:46 UTC (permalink / raw)
To: davem, ilpo.jarvinen; +Cc: ncardwell, nanditad, netdev, Yuchung Cheng
Correctly implement a loss detection heuristic: New sequences (above
high_seq) sent during the fast recovery are deemed lost when higher
sequences are SACKed.
Current code does not catch these losses, because tcp_mark_head_lost()
does not check packets beyond high_seq. The fix is straight-forward by
checking packets until the highest sacked packet. In addition, all the
FLAG_DATA_LOST logic are in-effective and redundant and can be removed.
The new sequences sent during fast-recovery maybe marked as lost
and/or retransmitted. It is possible these (new) losses are recovered
within the current fast recovery and the state moves back to CA_Open
without entering another fast recovery / cwnd redunction. This is
especially possible for light losses. Note RFC 3517 (implicitly)
allows this as well.
Update the loss heuristic comments. The algorithm above is documented
as heuristic B, but it is redundant too because heuristic A already
covers B.

Yep, I can do that easily, and probably send that out this week,

Sounds like the right thing to do; I will take a look at this to see
how involved it is. I don't think there should be any problem
getting it in with the remaining SF changes for 3.4 content in
the new year.

* Crash in ip_expire/icmp_send - 2.6.38.2 (Ubuntu 11.04 natty)
From: Tim Hartrick @ 2011-12-28 3:32 UTC (permalink / raw)
To: netdev
netdev,
We have observed the crash cited below on a number of our load-balancing
systems recently. The systems in question are running LVS in DR mode on
two pairs of bonded (ifenslave) 1G Intel interfaces. There is very
little else running on the systems. This particular instance occurred
within seconds of using "ip route add a.b.c.d/x dev bond1" but we have
observed it on other occasions.
Using crash the problem has been isolated to this section of code:
void icmp_send(struct sk_buff *skb_in, int type, int code, __be32 info)
{
struct iphdr *iph;
int room;
struct icmp_bxm icmp_param;
struct rtable *rt = skb_rtable(skb_in);
struct ipcm_cookie ipc;
__be32 saddr;
u8 tos;
struct net *net;
struct sock *sk;
if (!rt)
goto out;
net = dev_net(rt->dst.dev);
/*
* Find the original header. It is expected to be valid, of course.
* Check this, icmp_send is called from the most obscure devices
* sometimes.
*/
iph = ip_hdr(skb_in);
The crash occurs because the rt->dst.dev is NULL. The crash occurs at
icmp_send+95. I will be happy to furnish the dump for further
inspection upon request.

Well known and fixed a long time ago, see the patch below.
Please reproduce bugs against current upstream kernels before
reporting the problem here, if it only occurs in the vendor's
kernel then the appropriate thing to do is to report it to
the vendor.

net: ip_expire() must revalidate route
Commit 4a94445c9a5c (net: Use ip_route_input_noref() in input path)
added a bug in IP defragmentation handling, in case timeout is fired.
When a frame is defragmented, we use last skb dst field when building
final skb. Its dst is valid, since we are in rcu read section.
But if a timeout occurs, we take first queued fragment to build one ICMP
TIME EXCEEDED message. Problem is all queued skb have weak dst pointers,
since we escaped RCU critical section after their queueing. icmp_send()
might dereference a now freed (and possibly reused) part of memory.
Calling skb_dst_drop() and ip_route_input_noref() to revalidate route is
the only possible choice.

2) netem erroneously calls vfree() under spinlock and soft interrupt

3) ctnetlink_get_expect() can make nfnetlink loop forever when it

4) Autoloading connection tracking helpers cannot be done with

Regarding your comments to my previous post, none of them was omitted. I
reworked code according to them and added extended comments in a patch
explaining why I can't follow your hint. The issue with 'bool' you marked
was in another patch (#14) which I already fixed.
Of course I'm newcomer here, so there are lots refinements I don't
know about and may understand you incorrectly.

Alex

* [PATCH 1/1] via-rhine: Fix hanging with high CPU load on low-end broads.
From: Bjarke Istrup Pedersen @ 2011-12-28 12:28 UTC (permalink / raw)
To: linux-kernel; +Cc: netdev, Roger Luethi, Bjarke Istrup Pedersen
Working around problem causing high CPU load and hanging system when
there is alot of network trafic.
It is kind of an ugly way to work around it, but it allows the Soekris
net5501 to have trafic between two of it's NICs without hanging so much
that the watchdog kicks in and does a hard reboot of the system.
There is more info on the problem here:
http://http://lists.soekris.com/pipermail/soekris-tech/2010-October/016889.html
Tested with positive results on two Soekris net5501-70 boxes.

This is not correct and actually makes ss work differently on proc
vs netlink -- in the former case 0 is reported.

* [PATCH 3/5] inet_diag: Extend the meminfo report
From: Pavel Emelyanov @ 2011-12-28 13:38 UTC (permalink / raw)
To: David Miller, Linux Netdev List
Add the backlog length and wmem and rmem buffers limits.
With this the TCP memory info is full and can be analyzed.
Few words about extending the existing structure. The nla engine stores lengths of
fields and the nla parser will parse the new format successfully (checked on the ss
tool). But new apps will have to take this field's length into account. Hopefully
this is acceptable price for not introducing another ext bit and structure.

Prepare the ECN match for augmentation by an IPv6 counterpart. Since
no symbol dependencies to ipv6.ko are added, having a single ecn match
module is the more so welcome.

Use the new macro and struct names in xt_ecn.h, and put the old
definitions into a definition-forwarding ipt_ecn.h.
