The 16 concurrent streams lockup. The "rest of the system" keeps going.
I've had the same hang happen with 3.14.0-rc2 as well. I was able to
take a crash dump via "echo c > /proc/sysrq-trigger" but I have no clue
how to look at it. More than willing to upload it to netperf.org.

Remove one inline keyword, and no need for a loop to find
an index into a table.

* [PATCH Resend] net: asix: add missing flag to struct driver_info
From: Emil Goode @ 2014-02-13 18:30 UTC (permalink / raw)
To: David S. Miller, Ming Lei, Mark Brown, Jeff Kirsher, Glen Turner
Cc: linux-usb, netdev, linux-kernel, Emil Goode
The struct driver_info ax88178_info is assigned the function
asix_rx_fixup_common as it's rx_fixup callback. This means that
FLAG_MULTI_PACKET must be set as this function is cloning the
data and calling usbnet_skb_return. Not setting this flag leads
to usbnet_skb_return beeing called a second time from within
the rx_process function in the usbnet module.

But still it doesn't deserve a pr_notice()... pr_info() should be enough.

Right, those are actually inherited from the BCM54xx PHY driver, I
will move those register to a common location e.g: brcmphy.h

I would rather keep those as comments as they might change over time

I would rather keep this function simple like it is today since this
really is only required for entering suspend mode properly while
bcm7445_config_init() as the name suggests is specific to 7445 only.
Thanks for the review!

Maybe printing "using protocol version X" will make it appear less like
a debugging message referring to packet contents or something similar.

With pr_info it'll still appear in dmesg, and it'll still be "random
non-sensical message appears over and over in dmesg" type of
situation, to the vast majority of users. Do we need a print every
time someone creates a new tcp connection too? I'm still not totally
clear on the cause of this message getting printed, but I was seeing
it a whole bunch in my configuration...

Maybe making all the ip_set messages be prefixed with "ip_set: "
would help too.
Add pr_fmt
Remove embedded ip_set prefixes
Convert pr_warning to pr_warn
Realign arguments

All the masking should not be needed, as the bit timing is calculated

Don't depend on any state here, I suggest to do a softreset (or

You've copied my speudo code :)
But you have to use (cf->can_dlc > 0) here, as dlc is the shifted value.

If this is true, there is a Bug in the flow control. It should be moved
to the beginning of the function, see at91_can's xmit function.
/* Check if the TX buffer is full */

This is a the regular flow control function and must be called before a
TX complete interrupt can trigger. Your tx-complete interrupt is
probably always enabled?
So here you check the fill level of the FIFO:
if ((priv->tx_head - priv->tx_tail) ==
priv->xcan_echo_skb_max_tx)
netif_stop_queue(ndev);
If it's full, stop the queue. The you trigger the tx, the tx complete
interrupt gets called and the queue will be restarted.

Is this a read-modify-write register? I mean will an interrupt get
disabled, if you write a 0-bit in the IER register? What does the ICR
register?

This all simplyfies to a:
can_get_echo_skb(ndev, priv->tx_tail %
priv->xcan_echo_skb_max_tx);
priv->tx_tail++;
I think you should add some kind of loop here, it there is more than one
tx-complete per IRQ.

This started as a (misdirected) netdev thread wherein I was reporting a
non-trivial slowdown in the serial creation/manpipulation of lots of
network namespaces in 3.13.0 compared to 3.12.9 and 3.5.0-44+ (the
latter a Canonical kernel with some further added commits). I've since
found that 3.13.0 appears to scale better with parallel streams of such
things (*) so I'm not as concerned about the serial slowdown, but in the
meantime I've also encountered, three or four times now but not
consistently, some "hangs" when I have 16 streams of these namespace
creations/manipulations going-on on a two socket E5-2670 system.
I've seen the hang on both 3.13.0 and 3.14.0-rc2 now (kernel from a
linux-stable tree, using the config of the 3.5.0-44 kernel), and from
the 3.14.0-rc2 kernel I've gotten a crash dump via sysreq_trigger. I
lack the knowledge to debug the crash dump but can put it up on netperf.org.
I also got the attached from the 3.13.0 kernel (before someone told me
about sysreq_trigger).
These lockups seem to affect only the 16 streams creating/manipulating
(all adds, no deletes) the namespaces, the rest of the system (as far as
I've tried it) remains going.
I've seen the hang both with this "light" script:
#Assumed to be called as add_fake_router <sudo>
SUDO=$1
j=`uuidgen`
$SUDO ip netns add bar-${j}
$SUDO ip netns exec bar-${j} ip link set lo up
$SUDO ip netns exec bar-${j} sysctl -w net.ipv4.ip_forward=1 > /dev/null
k=`echo $j | cut -b -11`
$SUDO /home/rjones2/iproute2_tot/ip/ip link add ro-${k} type veth peer
name ri-${k} netns bar-${j}
$SUDO /home/rjones2/iproute2_tot/ip/ip link add go-${k} type veth peer
name gi-${k} netns bar-${j}
as well as a "heavier" one which does many more ip netns exec commands
against each namespace.

(*) well, four streams of "heavy" on 3.13.0 start-out still slower than
3.5.0-44+ but it crosses to above the first's "namespaces vs time" curve
by around 2000 namespaces, 8 streams on 3.5.0-44 is the same as 4, 8
streams on 3.13.0 is faster than 4 all the way out to 4000 namespaces
(the limit of my testing), and 16 streams on 3.13.0 starts out faster
than 8 on 3.13.0 but its curve crosses under that of 8 on 3.13.0 at
about 1300 or 1400 namespaces. But I digress and can provide that
data/spreadsheet if another thread is warranted.

* Occasional lockups creating/manipulating namespaces in 3.13.0 and 3.14.0-rc2
From: Rick Jones @ 2014-02-13 19:45 UTC (permalink / raw)
To: linux-kernel; +Cc: netdev
In-Reply-To: <52FAC6D1.50702@hp.com>
[-- Attachment #1: Type: text/plain, Size: 2427 bytes --]
This started as a (misdirected) netdev thread wherein I was reporting a
non-trivial slowdown in the serial creation/manpipulation of lots of
network namespaces in 3.13.0 compared to 3.12.9 and 3.5.0-44+ (the
latter a Canonical kernel with some further added commits). I've since
found that 3.13.0 appears to scale better with parallel streams of such
things (*) so I'm not as concerned about the serial slowdown, but in the
meantime I've also encountered, three or four times now but not
consistently, some "hangs" when I have 16 streams of these namespace
creations/manipulations going-on on a two socket E5-2670 system.
I've seen the hang on both 3.13.0 and 3.14.0-rc2 now (kernel from a
linux-stable tree, using the config of the 3.5.0-44 kernel), and from
the 3.14.0-rc2 kernel I've gotten a crash dump via sysreq_trigger. I
lack the knowledge to debug the crash dump but can put it up on netperf.org.
I also got the attached from the 3.13.0 kernel (before someone told me
about sysreq_trigger).
These lockups seem to affect only the 16 streams creating/manipulating
(all adds, no deletes) the namespaces, the rest of the system (as far as
I've tried it) remains going.
I've seen the hang both with this "light" script:
#Assumed to be called as add_fake_router <sudo>
SUDO=$1
j=`uuidgen`
$SUDO ip netns add bar-${j}
$SUDO ip netns exec bar-${j} ip link set lo up
$SUDO ip netns exec bar-${j} sysctl -w net.ipv4.ip_forward=1 > /dev/null
k=`echo $j | cut -b -11`
$SUDO /home/rjones2/iproute2_tot/ip/ip link add ro-${k} type veth peer
name ri-${k} netns bar-${j}
$SUDO /home/rjones2/iproute2_tot/ip/ip link add go-${k} type veth peer
name gi-${k} netns bar-${j}
as well as a "heavier" one which does many more ip netns exec commands
against each namespace.

(*) well, four streams of "heavy" on 3.13.0 start-out still slower than
3.5.0-44+ but it crosses to above the first's "namespaces vs time" curve
by around 2000 namespaces, 8 streams on 3.5.0-44 is the same as 4, 8
streams on 3.13.0 is faster than 4 all the way out to 4000 namespaces
(the limit of my testing), and 16 streams on 3.13.0 starts out faster
than 8 on 3.13.0 but its curve crosses under that of 8 on 3.13.0 at
about 1300 or 1400 namespaces. But I digress and can provide that
data/spreadsheet if another thread is warranted.

* [Patch net-next] net: introduce netdev_alloc_pcpu_stats() for drivers
From: Cong Wang @ 2014-02-13 19:46 UTC (permalink / raw)
To: netdev; +Cc: David S. Miller, Cong Wang
There are many drivers calling alloc_percpu() to allocate pcpu stats
and then initializing ->syncp. So just introduce a helper function for them.

Not much to see, unfortunately. The COUNT doesn't reflect the number packets
that I am missing.
LOCATION OFFSET COUNT
ieee80211_iface_work 208 1
> Strange that the problem disappears if you enable no_pmtu_disc then.
It seems with PMTU the initial mtu is the one of the device (1500). So the
original packet will have that size, but is subsequently wrapped into ESP and
UDP, which add to that size. And the final packet is then larger than the device
MTU... I know nothing about the ip / xfrm kernel code, so it's hard for me to
verify if that theory is real.
Thanks,
Ortwin

Yes, because it erronously got moved into the netns init function.
And thats what causes the spew. Moving it back into module init
function should be enough.

I don't think the kernel log is the correct place to put documentation.
A reference alone should be enough.

This doesn't seem very helpful to non-developers. You could instead

This is wrong. You overwrite the current config before validating it.

On tx yes. But how about rx? I don't see it there (rx_handler path).
