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

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.

Am I missing something or does it really completely lacks any locking?

OK, now if you had SH7734 manual to completely confirm that check sum is
stored in the same place there... most probably it is, of course, and we
should merge 'hw_crc' and 'shift_rd0' into a single field.

No, I liked your last version more. At least it's more consistent, not
adding separate values for either TR[1:0] or soft reset bits.

I doubt we can come up with something better.

* [PATCH] net: rds: fix per-cpu helper usage
From: Gerald Schaefer @ 2014-01-16 15:54 UTC (permalink / raw)
To: Shan Wei, Christoph Lameter, David S. Miller, Venkat Venkatsubra
Cc: rds-devel, netdev, linux-kernel, Martin Schwidefsky,
Frank Blaschka, Sebastian Ott, Gerald Schaefer
commit ae4b46e9d "net: rds: use this_cpu_* per-cpu helper" broke per-cpu
handling for rds. chpfirst is the result of __this_cpu_read(), so it is
an absolute pointer and not __percpu. Therefore, __this_cpu_write()
should not operate on chpfirst, but rather on cache->percpu->first, just
like __this_cpu_read() did before.

* [PATCH] net: introduce SO_BPF_EXTENSIONS
From: Michal Sekletar @ 2014-01-16 16:14 UTC (permalink / raw)
To: netdev; +Cc: Michal Sekletar, Michael Kerrisk, Daniel Borkmann, David Miller
userspace packet capturing libraries (e.g. libpcap) don't have a way how to find
out which BPF extensions are supported by the kernel, except compiling a filter
which uses extensions and trying to apply filter to the socket. This is very
inconvenient.
Therefore this commit introduces new option which can be used as an argument for
getsockopt() and allows one to obtain information about which BPF extensions are
supported by the kernel.

* [PATCH V3 net-next 1/3] ipv6: add the IPV6_FL_F_REFLECT flag to IPV6_FL_A_GET
From: Florent Fourcot @ 2014-01-16 16:19 UTC (permalink / raw)
To: netdev; +Cc: Florent Fourcot
With this option, the socket will reply with the flow label value read
on received packets.
The goal is to have a connection with the same flow label in both
direction of the communication.

* [PATCH V3 net-next 2/3] ipv6: add a flag to get the flow label used remotly
From: Florent Fourcot @ 2014-01-16 16:19 UTC (permalink / raw)
To: netdev; +Cc: Florent Fourcot
In-Reply-To: <1389889158-1710-1-git-send-email-florent.fourcot@enst-bretagne.fr>
This information is already available via IPV6_FLOWINFO
of IPV6_2292PKTOPTIONS, and them a filtering to get the flow label
information. But it is probably logical and easier for users to add this
here, and to control both sent/received flow label values with the
IPV6_FLOWLABEL_MGR option.

* [PATCH V3 net-next 3/3] ipv6: add flowlabel_consistency sysctl
From: Florent Fourcot @ 2014-01-16 16:19 UTC (permalink / raw)
To: netdev; +Cc: Florent Fourcot
In-Reply-To: <1389889158-1710-1-git-send-email-florent.fourcot@enst-bretagne.fr>
With the introduction of IPV6_FL_F_REFLECT, there is no guarantee of
flow label unicity. This patch introduces a new sysctl to protect the old
behaviour, enable by default.
Changelog of V3:
* rename ip6_flowlabel_consistency to flowlabel_consistency
* use net_info_ratelimited()
* checkpatch cleanups

* [PATCH net-next] ipv6: tcp: fix flowlabel value in ACK messages send from TIME_WAIT
From: Florent Fourcot @ 2014-01-16 16:21 UTC (permalink / raw)
To: netdev; +Cc: Florent Fourcot
This patch is following the commit b903d324bee262 (ipv6: tcp: fix TCLASS
value in ACK messages sent from TIME_WAIT).
For the same reason than tclass, we have to store the flow label in the
inet_timewait_sock to provide consistency of flow label on the last ACK.

Interesting idea.
Could this break some existing htb setups ?
Also we test cl being NULL at line 222, it would be nice to not test it

Or a timing issue. Adding a WARN_ON() adds extra instructions and might
really change the assembly output.

Its totally possible some barrier was not properly handled by the
compiler. You could disassemble the function on both toolchains and
try to spot the issue.

Yes I think this would work, we could call napi_disable(), read the
average packet length from the receive_queue, and then call
virtnet_napi_enable(). That would eliminate the need for the seqcount.
Best,

This should rather be in: include/linux/filter.h
And then, maybe be renamed into something like bpf_tell_extensions()
for example, but that's just nit.
Also, please add a comment, saying if people add new extensions, they
need to enumerate them within this function from now on so that user
space who enquires for that can be made aware of.
Still, grepping through latest libpcap sources, tells me, so far over
the years they have included SKF_AD_PROTOCOL and SKF_AD_PKTTYPE, wow!
That's very disappointing, so I have high hopes with this getsockopt().
;)
Thanks,
Daniel

Adding flow director support would be a good step, Zhi's patches for
support in tun have been merged, so support in virtio-net would be a
good follow on. But, flow-director does have some limitations and
performance issues of it's own (forced pairing between TX and RX
queues, lookup on every TX packet). In the case of virtualization,
aRFS, RSS, ntuple filtering, LRO, etc. can be implemented as software
emulations and so far seems to be wins in most cases. Extending these
down into the stack so that they can leverage HW mechanisms is a good
goal for best performance. It's probably generally true that most of
the offloads commonly available for NICs we'll want in virtualization
path. Of course, we need to deomonstrate that they provide real
performance benefit in this use case.
I believe tying in aRFS (or flow director) into a real aRFS is just a
matter of programming the RFS table properly. This is not the complex
side of the interface, I believe this already works with the tun
patches.

I don't think this is necessarily true. Per flow steering amongst
virtual queues should be beneficial in itself. virtio-net can leverage
RFS or aRFS where it's available.

1. The aRFS interface for the guest to specify which virtual queue to
receive a packet on is fairly straight forward.
2. To hook into RFS, we need to match the virtual queue to the real
CPU it will processed on, and then program the RFS table for that flow
and CPU.
3. NIC aRFS keys off the RFS tables so it can program the HW with the
correct queue for the CPU.

* [PATCH] net: introduce SO_BPF_EXTENSIONS
From: Michal Sekletar @ 2014-01-16 17:13 UTC (permalink / raw)
To: dborkman; +Cc: netdev, Michal Sekletar, Michael Kerrisk, David Miller
In-Reply-To: <52D80BCA.7030400@redhat.com>
userspace packet capturing libraries (e.g. libpcap) don't have a way how to find
out which BPF extensions are supported by the kernel, except compiling a filter
which uses extensions and trying to apply filter to the socket. This is very
inconvenient.
Therefore this commit introduces new option which can be used as an argument for
getsockopt() and allows one to obtain information about which BPF extensions are
supported by the kernel.

Sure, that works and I actually like it. This is supported by the c standard,
but please don't ask me since which one. ;)
