* [PATCH] net: Small bug on rxhash calculation
From: Chema Gonzalez @ 2012-09-06 6:35 UTC (permalink / raw)
To: netdev; +Cc: edumazet, Chema Gonzalez
>From 5c02179069826bfba9360383b88601b31ff05517 Mon Sep 17 00:00:00 2001
From: Chema Gonzalez <chema@google.com>
Date: Wed, 5 Sep 2012 17:05:48 -0700
Subject: [PATCH] net: Small bug on rxhash calculation
While the (current) sorting of the ports/addresses is coherent
(you get the same rxhash for packets sharing the same (unsorted)
4-tuple), ports and addresses should not be sorted independently,
which currently are: For traffic between A=S:l and B=L:s, packets
in both directions would get their rxhash from hashing
{L, S, {s, l}}. The same rxhash is obtained from packets between
C=S:s and D=L:l.
This patch ensures traffic between A and B gets their rxhash
from {S, L, {s, l}}, and traffic between C and D from {S, L,

Could it be that these processes missing 50+ packets provide a non
accessible area of memory and these recvmsg() calls return EFAULT ?
Are you using special memory areas, using mprotect(), or huge pages for
example ?

What NIC driver are you using ?
Could you trace if skb_copy_and_csum_datagram_iovec() or
skb_copy_datagram_iovec() returns an error (it could be EFAULT by
example) ?
If so, you could add some debugging to these functions to track what
exact error it is
It seems following patch is needed anyway :

David, Ben,
many thanks for your notes and review. I'll apply them and re-test the

The Ethernet API we are using does not support transmitting multiple Ethernet
frames in a single call, so the aggregation things should be done inside low
level driver, in fact it is just what some wlan(802.11n) drivers have
been doing.
IMO, the current .tx_fixup is intelligent enough to handle aggregation:
- return a skb_out for sending if low level drivers think it is
ready to send
the aggregated frames
- return NULL if the low level drivers think they need to wait
for more frames
Of course, the low level drivers need to start a timer to trigger sending
remainder frames in case of timeout and no further frames come from
upper protocol stack.
Looks the introduced .tx_bundle is not necessary since .tx_fixup is OK.

IMO, usbnet only cares how to send out the aggregated frame, and
doesn't mind how the packets are aggregated. Also the way of
aggregation is per low level driver and should be handled by low
level driver.

The timeout timer is removed, so I am wondering how the low level driver or
usbnet handle the wait_for_more?

No send out skb, so you still want usbnet to transmit the NULL frame?
Also the current skb to send is not stored in ctx->tx_rem_skb, it will be lost.

So you basically replace .tx_fixup as .tx_bundle for ncm, don't you?
This also is what I commented above: .tx_fixup is enough for aggregation, :-)

* Increased multicast packet drops in 3.4
From: Shawn Bohrer @ 2012-09-06 0:11 UTC (permalink / raw)
To: netdev; +Cc: eric.dumazet
I've been testing the 3.4 kernel compared to the 3.1 kernel and
noticed my application is experiencing a noticeable increase in packet
drops compared to 3.1. In this case I have 8 processes all listening
on the same multicast group and occasionally 1 or more of the
processes will report drops based on gaps in the sequence numbers on
the packets. One thing I find interesting is that some of the time 2
or 3 of the 8 processes will report that they missed the exact same
50+ packets. Since the other processes receive the packets I know
that they are making it to the machine and past the driver.
So far I have not been able to _see_ any OS counters increase when the
drops occur but perhaps there is a location that I have not yet
looked. I've been looking for drops in /proc/net/udp /proc/net/snmp
and /proc/net/dev.
I've tried using dropwatch/drop_monitor but it is awfully noisy even
after back porting many of the patches Eric Dumazet has contributed to
silence the false positives. Similarly I setup trace-cmd/ftrace to
record skb:kfree_skb calls with a stacktrace and had my application
stop the trace when a drop was reported. From these traces I see a
number of the following:
md_connector-12791 [014] 7952.982818: kfree_skb: skbaddr=0xffff880583bd7500 protocol=2048 location=0xffffffff813c930b
md_connector-12791 [014] 7952.982821: kernel_stack: <stack trace>
=> skb_release_data (ffffffff813c930b)
=> __kfree_skb (ffffffff813c934e)
=> skb_free_datagram_locked (ffffffff813ccca8)
=> udp_recvmsg (ffffffff8143335c)
=> inet_recvmsg (ffffffff8143cbfb)
=> sock_recvmsg_nosec (ffffffff813be80f)
=> __sys_recvmsg (ffffffff813bfe70)
=> __sys_recvmmsg (ffffffff813c2392)
=> sys_recvmmsg (ffffffff813c25b0)
=> system_call_fastpath (ffffffff8148cfd2)
Looking at the code it does look like these could be the drops, since
I do not see any counters incremented in this code path. However I'm
not very familiar with this code so it could also be a false positive.
It does look like the above stack only gets called if
skb_has_frag_list(skb) does this imply the packet was over one MTU
(1500)?
I'd appreciate any input on possible causes/solutions for these drops.
Or ways that I can further debug this issue to find the root cause of
the increase in drops on 3.4.
Thanks,
Shawn

The ethtool core does that for you. (Drivers can't be trusted to do
it!)

Note that the version field is supposed to be the version of the
register dump format. Is this value sufficient for userland to easily
decide whether macb_is_gem()? Are there spare bits that you can set if
you change the format later?

Why is this rather larger than the actual number of registers you
return? Also, the name is not a great idea as 'regs_len' is normally a
number of bytes.

* [net-next 6/6] igb: Add 1588 support to I210/I211.

From: Matthew Vick <matthew.vick@intel.com>
Previously I210/I211 followed the same code flow as 82580/I350 for 1588.
However, since the register sets have changed, we must update the
implementation to accommodate the register changes.

* [net-next 5/6] igb: Prevent dropped Tx timestamps via work items and interrupts.
From: Jeff Kirsher @ 2012-09-05 23:35 UTC (permalink / raw)
To: davem; +Cc: Matthew Vick, netdev, gospo, sassmann, Richard Cochran,
Jeff Kirsher
In-Reply-To: <1346888106-25638-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Matthew Vick <matthew.vick@intel.com>
In rare circumstances, it's possible a descriptor writeback will occur
before a timestamped Tx packet will go out on the wire, leading to the
driver believing the hardware failed to timestamp the packet. Schedule a
work item for 82576 and use the available time sync interrupt registers
on 82580 and above to account for this.

* [net-next 2/6] igb: Update PTP function names/variables and locations.
From: Jeff Kirsher @ 2012-09-05 23:35 UTC (permalink / raw)
To: davem; +Cc: Matthew Vick, netdev, gospo, sassmann, Richard Cochran,
Jeff Kirsher
In-Reply-To: <1346888106-25638-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Matthew Vick <matthew.vick@intel.com>
Where possible, move PTP-related functions into igb_ptp.c and update the
names of functions and variables to match the established coding style
in the files and specify that they are PTP-specific.

Update ethtool_get_ts_info to not report any supported functionality on
82575 and add support for V2 Sync and V2 Delay packets. In the case
where CONFIG_IGB_PTP is not defined, we should be reporting default
values.
v2: Correct the function to return EOPNOTSUPP when there is no PTP support
or the device does not support PTP. Also fix minor whitespace issue.

From: Matthew Vick <matthew.vick@intel.com>
For users without CONFIG_IGB_PTP=y, we should not be compiling any PTP
code into the driver. Tidy up the wrapping in igb to support this.

This series contains updates to igb (specifically PTP code).
The following are changes since commit f6fe569fe056388166575af1cfaed0bcbc688305:
Revert "usbnet: drop unneeded check for NULL"
and are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next master
Matthew Vick (6):
igb: Tidy up wrapping for CONFIG_IGB_PTP.
igb: Update PTP function names/variables and locations.
igb: Correct PTP support query from ethtool.
igb: Store the MAC address in the name in the PTP struct.
igb: Prevent dropped Tx timestamps via work items and interrupts.

Related to hardware revisions (which don't belong here, as David said),
I rather doubt this CVS ID is very useful as a driver version.
If the driver doesn't have a meaningful version (aside from the kernel
version) then you can remove this function and let the ethtool core fill
in the other two fields automatically.

Not speaking for my employer; that's the marketing department's job.
They asked us to note that Solarflare product names are trademarked.
