Come to think of it, this should probably be bool to
avoid anyone possibly using this in a sorting function.

Hmmm, wouldn't it make more sense to make ip6tables use a special
accessor than to penalize everyone?

I dont think this 8bytes alignment is possible with ip6tables.

Thanks for running a quick test. I don't find anything obvious wrong in descriptor dump.

When you said you had this issue with RHEL5 and RHEL6 drivers, have you install RHEl5/6 kernel and reproduced it? If so I think I should install RHEL6 and try reproduce it locally!

Hi Li

This seems a huge amount of code, on an already complex stack.

I am not convinced its needed. It looks like a debugging aid you had to
write in order to understand better linux network stack.

Lets see if you manage to maintain this for a while before considering
upstreaming it.

You said that some 'buggy' drivers set rxhash to zero, but its a valid
operation.

You said 'it seems that RPS hashing can not work well for some corner
cases', but its a known fact.

Thanks

Maybe we can even be sure that they are 64-bit aligned too?

If there's an embedded u64 in the in6_addr union, they really should
be.

It can't even be an issue in the protocol headers, because in the
socket demux we read the two 32-bit ipv4 addresses in the packet
header as one 64-bit chunk already.

Thanks Eric.  This looks very sensible.

Ok I made a special function to implement this encoding.

Yep, the ipv6 hash calculation needs the same __force'ing.

On 64 bit arches having efficient unaligned accesses (eg x86_64) we can
use long words to reduce number of instructions for free.

Hi Tushar,

Thanks for you quick reply but disabled tso no help for this issue:

# ethtool -k eth0
Offload parameters for eth0:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp segmentation offload: off
udp fragmentation offload: off
generic segmentation offload: on
generic-receive-offload: on

kernel log after disable tso:

Thanks for info. I see that hang occurs right when HW processing first TX descriptor with TSO.
Would you be able to reproduce issue with TSO off?  Disable TSO by 'ethtool -K ethx tso off'
Let all debug enabled as it is,  that will help us debug further if issue occurs with TSO off.

* [RFC][PATCH 4/4] skbtrace: four TCP/IP tracepoints tcp/icsk_connection,tcp_sendlim,tcp_congestion
From: Li Yu @ 2012-07-11  2:18 UTC (permalink / raw)
  To: Linux Netdev List
In-Reply-To: <4FFBC6B6.2000600@gmail.com>

From: Li Yu <bingtian.ly@taobao.com>

This implements four skbtrace traces for TCP.

(1) tcp/icsk_connection is for trace basic state
    migration of TCP protocol, e.g. SYN_RECV ->
    ESTABLISHED.
(2) tcp_sendlim is for trace TCP sending limitation.
    e.g. congestion window is limited to send segments.

(3) tcp_congestion is for trace TCP congestion events,
    e.g. Loss, FRTO and etc.

Thanks.

* [RFC][PATCH 3/4] skbtrace: TCP/IP family support
From: Li Yu @ 2012-07-11  2:17 UTC (permalink / raw)
  To: Linux Netdev List
In-Reply-To: <4FFBC6B6.2000600@gmail.com>

From: Li Yu <bingtian.ly@taobao.com>

This implements skbtrace support for TCP/IP protocol family, but it does
not contains any particular traces.

Basically, it just refactors a bit for XX_get_name(), which will be used
in some socket based traces.

Thanks.

* [RFC][PATCH 1/4] skbtrace: core feature
From: Li Yu @ 2012-07-11  2:17 UTC (permalink / raw)
  To: Linux Netdev List
In-Reply-To: <4FFBC6B6.2000600@gmail.com>

From: Li Yu <bingtian.ly@taobao.com>

This implements core feature of skbtrace, which contains glue code of
tracepoints subsystem and relay file system, and provide skbtrace API
for particular networking traces.

Thanks

* Re: [RFC] net:phy:phylib: phy shares the same interrupt with mac
From: Jason Lin @ 2012-07-11  1:32 UTC (permalink / raw)

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain; charset=GB2312, Size: 7855 bytes --]

Dear :
I describe my situation again.
In my hardware design, the interrupt (INT) pin of phy is connected to
the INT input pin of MAC.
In other words, one of triggering interrupt condition of MAC is
related to phy's interrupt.
So the phy will share the same "IRQ pin" with MAC.
As described above, the best solution is the INT pin of phy is
connected to architecture independently.
But, the hardware architecture cannot modify easily.
So I think
1. We can assign dummy IRQ number (which is a empty IRQ number but
large than zero) to phy.
phydev->irq = PHY_DUMMY_IRQ (this value is depend on architecture)
2. Change to do the soft IRQ in phy's ISR.
    To schedule workqueue in this soft IRQ.
In this way, the MAC can schedule phy's soft IRQ to do phy's work
queue (to do ack phy's interrupt ... etc).

Dose it make sense?

I don't think that's correct.
Look at what I posted again.

If it's IPv4, 

	if (a->family == AF_INET)
		return a->addr.a4 == b->addr.a4;

	return ipv6_addr_equal((const struct in6_addr *)&a->addr.a6,
			       (const struct in6_addr *)&b->addr.a6);

so it's a single word test or a 4 word test.

Your code is compare/branch/continue in a loop with an
increment and test.  I find it hard to believe that's
faster.  I suppose it _could_ be faster dependent on the
data in the words though.

What do I miss?

Is there a case where a->family is neither
AF_INET or AF_INET6?

* [PATCH net-next 5/9] qlge: Added missing case statement to ethtool get_strings.
From: Jitendra Kalsaria @ 2012-07-11  0:57 UTC (permalink / raw)
  To: davem; +Cc: netdev, ron.mercer, Dept_NX_Linux_NIC_Driver, Jitendra Kalsaria
In-Reply-To: <1341968259-18931-1-git-send-email-jitendra.kalsaria@qlogic.com>

From: Jitendra Kalsaria <jitendra.kalsaria@qlogic.com>

Missing case was causing ethtool self test to print garbage
value in extra info section.
