Putting a vlan device on eth1 actually affects the behavior of the
driver, which is why that works. I suspect that if you put the vlan
device on both the physical interface and the bridge you would see
packets with tags on the bridge.
Regardless, the solution is to remove the dependency on vlan devices
by converting over to the new vlan model. Francois, any chance that
you might have some time to look at this?

Jay explained that the current implementation should already trap those frames, on inactive slaves,
in modes where inactive slaves exist. I agree with him.
What mode are you seeing this problem in? If the current "should drop" logic is leaking, then yes,
we should fix it. But we currently don't see where it is leaking.

Notably, TCP is one caller that uses the error code. The error code
is functionally equivalent to ECN, one of whose great advantages is
reducing delay jitter. If TCP didn't get the error, that would
effectively double the latency for a full window of data, since the
dropped segment would not be retransmitted for an RTT.

Right... while I generally agree that a fixed-length drop-tail queue
isn't optimal, isn't this problem what the various AQM schemes try to
solve?

* [PATCHv2 net-next-2.6] ethtool: Compat handling for struct ethtool_rxnfc
From: Ben Hutchings @ 2011-02-28 21:55 UTC (permalink / raw)
To: David Miller, Alexander Duyck, Santwona Behera; +Cc: netdev, Kees Cook
This structure was accidentally defined such that its layout can
differ between 32-bit and 64-bit processes. Add compat structure
definitions and an ioctl wrapper function.
Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
---
Again, I have not tested this with a driver that implements the
ETHTOOL_{G,S}RXCLSRL* operations, and that clearly does need to be
tested. However, ETHTOOL_GRINGS and ETHTOOL_GDRVINFO continue to work
correctly from a 32-bit ethtool.
I'm not sure whether more checks on rule_cnt are required for security
or whether compat_alloc_user_space() and copy_in_user() can be relied on
to limit any buffer overrun to the user process's own memory. It looks
like this is safe on x86.
Ben.

Before testing, please insert:
||
copy_in_user(&rxnfc->rule_cnt, &compat_rxnfc->rule_cnt,
sizeof(rxnfc->rule_cnt))
before the final closing parenthesis above. (This got lost in one of
many revisions.)

NAK
This does not belong in ethtool. It should be done by rt_netlink_ops.
I am working on doing that right now.

Never mind, this is good. I was confusing slave with bridge initialization
and netdevice ops with ethtool ops.
Ethtool ops seems to be growing like weeds lately...

Isn't the patch also needed in 2.6.37.x?

I'm less familiar with the compat world, but it looks sane to me. All the
copy_in_user() calls are calculated based on structure sizes, right? Except
for the rule_cnt one, which was already bounds-checked for output. AFAIK,
reading beyond the end of &rxnfc->rule_locs[0] should be contained to
userspace memory due to the access_ok() check in copy_in_user().

[...]
No, because the native ioctl implementation writes out the actual number
of rules to rxnfc->rule_cnt and we then read that back into rule_cnt
before performing the copy from rxnfc->rule_locs to
compat_rxnfc->rule_locs. So userland can race with us and modify that
value.
We could use the original value of rule_cnt to calculate the size to
copy; it would just mean copying more than we need to most of the time.

I think it would also be appropriate to add this to the output of the

I really don't want to introduce different syntax for functionality that
is common between the two command sets. The user should not have to
know that driver A implements interface I and driver B implements
interface J, except that since version 2.6.y driver A implements
interface J too.
Surely it is possible to try one interface, then the other, when the
requested filter can be implemented either way?

Agreed, that would be a useful shortcut.

I am not an expert on exactly how Linux does this, but for Cisco and for
instance ATM interfaces, there are two stages of queuing. One is the
"hardware queue", which is a FIFO queue going into the ATM framer. If one
wants low CPU usage, then this needs to be high so multiple packets can be
put there per interrupt. Since AQM is working before this, it also means
the low-latency-queue will have a higher latency as it ends up behind
larger packets in the hw queue.
So on what level does the AQM work in Linux? Does it work similarily, that
txqueuelen is a FIFO queue to the hardware that AQM feeds packets into?
Also, when one uses WRED the thinking is generally to keep the average
queue len down, but still allow for bursts by dynamically changing the
drop probability and where it happens. When there is no queuing, allow for
big queue (so it can fill up if needed), but if the queue is large for
several seconds, start to apply WRED to bring it down.
There is generally no need at all to constantly buffer > 50 ms of data,
then it's better to just start selectively dropping it. In time of
burstyness (perhaps when re-routing traffic) there is need to buffer
200-500ms of during perhaps 1-2 seconds before things stabilize.
So one queuing scheme and one queue limit isn't going to solve this, there
need to be some dynamic built into the system for it to work well.
AQM needs to feed into a relatively short hw queue and AQM needs to exist
on output also when the traffic is sourced from the box itself, no tonly
routed. It would also help if the default would be to use let's say 25% of
the bandwidth for smaller packets (< 200 bytes or so) which generally are
for interactive uses or are ACKs.

* [PATCH] sched: QFQ - quick fair queue scheduler (v2)
From: Stephen Hemminger @ 2011-03-01 1:17 UTC (permalink / raw)
To: David Miller, Fabio Checconi, Luigi Rizzo; +Cc: netdev
This is an implementation of the Quick Fair Queue scheduler developed
by Fabio Checconi. The same algorithm is already implemented in ipfw
in FreeBSD. Fabio had an earlier version developed on Linux, I just
cleaned it up and tested it. All bugs are mine.
This version is still experimental, do not use for production.
Signed-off-by: Stephen Hemminger <shemminger@vyatta.com>

v2 - Did some debugging, and rebased against net-next tree.

Instead calculate the KVA of receive data. It's not like it's a hard sum.

* [PATCH net-next-2.6 3/8] sfc: Read MC firmware version when requested through ethtool
From: Ben Hutchings @ 2011-03-01 1:22 UTC (permalink / raw)
To: David Miller; +Cc: netdev, linux-net-drivers
In-Reply-To: <1298942169.3069.179.camel@localhost>
We currently make no use of siena_nic_data::fw_{version,build} except
to format the firmware version for ethtool_get_drvinfo(). Since we
only read the version at start of day, this information is incorrect
after an MC firmware update. Remove the cached version information
and read it via MCDI whenever it is requested.

* [PATCH net-next-2.6 4/8] sfc: Do not read STAT1.FAULT in efx_mdio_check_mmd()
From: Ben Hutchings @ 2011-03-01 1:22 UTC (permalink / raw)
To: David Miller; +Cc: netdev, linux-net-drivers
In-Reply-To: <1298942169.3069.179.camel@localhost>
This field does not exist in all MMDs we want to check, and all
callers allow it to be set (fault_fatal = 0).
Remove the loopback condition, as STAT2.DEVPRST should be valid
regardless of any fault.

* [PATCH net-next-2.6 7/8] sfc: Remove configurable FIFO thresholds for pause frame generation
From: Ben Hutchings @ 2011-03-01 1:23 UTC (permalink / raw)
To: David Miller; +Cc: netdev, linux-net-drivers
In-Reply-To: <1298942169.3069.179.camel@localhost>
In Falcon we can configure the fill levels of the RX data FIFO which
trigger the generation of pause frames (if enabled), and we have
module parameters for this.
Siena does not allow the levels to be configured (or, if it does, this
is done by the MC firmware and is not configurable by drivers).
So far as I can tell, the module parameters are not used by our
internal scripts and have not been documented (with the exception of
the short parameter descriptions). Therefore, remove them and always
initialise Falcon with the default values.
