Actually, the idea was that the remote could changed the flow label
during the lifetime of a connection.
I do not have a strong opinion on that, but in a "reflect" mode, I
except that the last received value will be in used.
Second, in case of SYN cookie, is the SYN flow label stored somewhere?
Thanks,

Would it make sense to sync the flowlabel if it changes with the socket, so
user space can query the label really used? Otherwise I wouldn't even report
it.
> Second, in case of SYN cookie, is the SYN flow label stored somewhere?
Should then be synced as soon as the cookie is validated. You can test it by
setting tcp_syncookies to 2. It uses syncookies unconditionally then.

What I thought is to split the implementation into two patches, this
patch fixes the rx path resource leak(just like what tx path does), then
a separate patch fixes gnttab_end_foreign_access_ref failure issue for
both tx/rx through taking reference to the page before
gnttab_end_foreign_access.
If you'd like they are posted together, I will create new patch for the
latter and then post them.:-)

Hi Hannes.
WARN_ON(ifp->idev->valid_ll_addr_cnt < 0);
We did hit once this warning during the tests. The person who hit this
says that it was during the setup of many macvlan devices.
I examined the code but I'm not sure how this could happen. Looks like a
race condition between addrconf_dad_completed() and addrconf_ifdown().
Not sure how to easily resolve that though.
Would you please take a look?
Thanks!

These properties are booleans, and optional? Does it mean that
you cannot _disable_ broken features? Or does it mean that you
_must_ specify the non-broken features and thus break backwards
compatibility? Or are these properties not boolean (they are not
used in the example either, unfortunately), and the binding text
would need an update for clarity? What am I missing?
virtually yours

* [PATCH net-next v4 0/2] stmmac: fix kernel crashes for jumbo frames
From: Vince Bridgers @ 2014-01-16 14:05 UTC (permalink / raw)
To: devicetree, netdev
Cc: peppe.cavallaro, robh+dt, pawel.moll, mark.rutland,

v4:
* Address inconsistent comment with use, add comments about inconsistency
of max-frame-size definition and use in the ePAPR v1.1 specification.
v3:
* change snps,max-frame-size to max-frame-size
v2:
* change snps,max-mtu to snps,max-frame-size
These patches address two kernel crashes seen when using jumbo frames on
the Synopsys stmmac driver, and adds device tree configurability for the
maximum mtu. The Synopsys emac fifo sizes can be configured when a logic
design is synthesized, but does not provide a way for a driver to query the
exact fifo size.
The crashes seen were due to two issues.
1) The dma buffer size was being set after the dma buffers were allocated.
This caused a crash when changing the mtu since it was possible the buffers
would subsequently be freed using an incorrect dma buffer size. This could
also cause kernel panics due to memory corruption since a large mtu size could
have been configured, but the dma buffers were not sized accordingly.
2) Jumbo frames were being enabled by default, but the dma buffers were not
sized accordingly. This caused memory corruption in the context of certain
types of network traffic, leading to kernel panics.
I've tested these changes using automated, reproducible testware. I can
demonstrate the panics described before the fixes and show that the fixes
address the problems described.
Testing and improvements continue through the use of the mentioned automated
and reproducible testware.

This change adds a parameter for the Synopsys 10/100/1000
stmmac Ethernet driver to configure the maximum frame
size supported by the EMAC driver. Synopsys allows the FIFO
sizes to be configured when the cores are built for a particular
device, but do not provide a way for the driver to read
information from the device about the maximum MTU size
supported as limited by the device's FIFO size.

In-Reply-To: <1389881155-9758-1-git-send-email-vbridgers2013@gmail.com>
These changes correct the following issues with jumbo frames on the
stmmac driver:
1) The Synopsys EMAC can be configured to support different FIFO
sizes at core configuration time. There's no way to query the
controller and know the FIFO size, so the driver needs to get this
information from the device tree in order to know how to correctly
handle MTU changes and setting up dma buffers. The default
max-frame-size is as currently used, which is the size of a jumbo
frame.
2) The driver was enabling Jumbo frames by default, but was not allocating
dma buffers of sufficient size to handle the maximum possible packet
size that could be received. This led to memory corruption since DMAs were
occurring beyond the extent of the allocated receive buffers for certain types
of network traffic.

I see at least one use case. In the same way that openssh sets the
tclass field after the SSH session initialization, a software could set
the label after the beginning of the L7 session (and ignoring QoS
priority for non-interactive packet at the beginning).

That seems to be the case. Actually we don't need to count precisiely
here, we just must precisiely identify the situation where the first
LL address comes into operational state. Maybe we can implement this
somehow differently. I'll play with the code soon.

They're not booleans. I'll update the text to make that clear.

Some hardware may be broken in interesting and board-specific ways, such
that various bits of functionality don't work. This patch provides a
mechanism for overriding mii registers during init based on the contents of
the device tree data, allowing board-specific fixups without having to
pollute generic code.

* [PATCH] sch_htb: let skb->priority refer to non-leaf class
From: Harry Mason @ 2014-01-16 14:45 UTC (permalink / raw)
To: Jamal Hadi Salim; +Cc: linux-netdev
If the class in skb->priority is not a leaf, apply filters from the
selected class, not the qdisc. This allows netfilter or user space
to partially classify the packet and tc filters to finish it off.

Just a style suggestion: rather than almost duplicating the same 12 lines
of code for each property, I think it can be split out into a helper
function.

Maybe something like this and then throw out the whole ll counting stuff:

You're not using them explicitly anymore. I'd update the changelog
with converting the function to one-liner.

I started with adding WARN_ON(sk == 0xffffffff); just before return in
__inet_lookup_established(), and the problem was gone. So this looks
very strange, like a toolchain problem.
I used gcc-linaro-arm-linux-gnueabihf-4.8-2013.05.
If I change the toolchain to
gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415
the problem seems to have gone away.
I attach the kernel config I used.
