* [PATCH RFC] xfrm: Don't queue retransmitted packets if the original is still on the host
From: Steffen Klassert @ 2013-10-16 11:42 UTC (permalink / raw)
To: Eric Dumazet; +Cc: David Miller, netdev
In-Reply-To: <20131016094549.GZ7660@secunet.com>
It does not make sense to queue retransmitted packets if the
original packet is still in some queue of this host. So add
a check to xdst_queue_output() and drop the packet if the
original packet is not yet sent.

Sure, we can increase the default value, maybe along with the ipv6 side.
Any recomendation on a good default for both?

Yes, it's undocumented. I'll take care of it.

* [PATCH] wanxl: fix info leak in ioctl
From: Salva Peiró @ 2013-10-16 10:46 UTC (permalink / raw)
To: netdev; +Cc: Salva Peiró, Krzysztof Halasa, security
The wanxl_ioctl() code fails to initialize the two padding bytes of
struct sync_serial_settings after the ->loopback member. Add an explicit
memset(0) before filling the structure to avoid the info leak.

This will add the relevant values like the gpios and the
type in rfkill_gpio_platform_data to the rfkill_gpio_data
structure. It will allow those values to be easily picked
from DT and ACPI tables later.

Use a simple flag to see the state of the clock, and make
the clock available even without a name. Also, get rid of
HAVE_CLK dependency.

This sets the direction of the gpio once when it's requested,
and uses the spinlock-safe gpio_set_state() to change the
state.

Hi,
The first patches prepare the driver for the support. The last patch
can then add the support quite easily. With these patches, adding DT
support later will be quite straight forward if someone needs it.

* IPv6 path discovery oddities - flushing the routing cache resolves
From: Valentijn Sessink @ 2013-10-16 10:31 UTC (permalink / raw)
To: netdev
Hello list,
I'm experiencing difficulties with IPv6 path discovery. The setup is
quite simple, a machine with native IPv6, no special routing - let's
call it the "server" for now. Unfortunately, I seem to loose
connectivity multiple times a day - and after digging in, I found this
to be "too big" messages that weren't honored at the server. The network
consists of something like:
server --- hosting --- others ---- SIXXS tunnel with 1280 MTU --- me.
A "ip -6 route list cache" would show a cached route to my "client", but
one without MTU. Then after "ip -6 route flush cache", and after trying
to send a large packet (for example issuing "ps uaxww" on an ssh
prompt), "ip -6 route list cache" will show a correct MTU.
But after a while, things start to go wrong again, and another "ip -6
route flush cache" is needed.
The server is running 3.8.0-something (ubuntu 12.04 with a newer kernel).
tcpdump shows that on reception of icmpv6 "too big", nothing happens
(i.e. the "too big" packet will be sent time and again), and after the
"ip -6 route flush cache", suddenly the "too big" message is honored.
I saw a couple of path discovery issues on this list, more specifically
one with the subject "IPv6 path MTU discovery broken" earlier this month
- but I'm not sure it's the same issue (because the original submitter
specifically mentions kernels 3.10 and 3.11 and has a much more
complicated routing table).
The "server" just has:
auto br0
iface br0 inet6 static
address 2a01:xxxx:xxx:xxxx::2
netmask 64
gateway fe80::1
bridge_ports eth0
bridge_maxwait 0
Nothing special, no special routes, no routing daemons.
If I can do anything to shine more light on this issue, please tell me so.
Best regards,
Valentijn

Got it. This doesn't seems the simpliest/best way to resolve this pb.
Can we not introduce another identifier (something like IFLA_NET_NS_ID),
which will not have such constraint?
inode is unique on the system, why not using it as an opaque value to
identitfy the netns (like 'ip netns identify' do)?

This is interesting, we could do the same check before we queue
the packet and drop it if the original packet is still in a host
queue.
I'll do a RFC patch.

Or check following to see what the if condition really do,
----------expires-------now-------credit---------- is the only case
where we need to add a timer.
Other cases like following would match the if condition above, then no
timer is added.
----------expires----------credit------now------
-----now-----expires----------credit----------
Or we can consider the extreme condition, when the rate control does not
exist, "credit_usec" is zero, and "next_credit" is equal to "expires".
The above if condition would cover all conditions, and no rate control
really happens. If credit_usec is not zero, the "if condition" would
cover the range outside of that from expires to next_credit.
Even if "now" is wrapped again into the range from "expires" to
"next_credit", the "next_credit" that is set in __mod_timer is
reasonable value(this can be gotten from credit_usec), and the timer
would be hit soon.

Looks correct to me...
In X.25 the lengths (in digits) of the called and calling addresses
are encoded in the high and low nibbles of one byte and then
followed by both addresses with a digit in each nibble.
If the length of the first address is odd, the second one
isn't byte aligned.

Not less than the absolute value ULONG_MAX/2, just less than ULONG_MAX/2
offset from "now". The time_eq macros deal with wraparound.
Looks like Jianhai and Wei are discussing a better fix than an
additional timer though.

Hi
I seem to have to take a second hurdle in using my Centrino Advanced-N 6235 with linux.
I'm trying to set the regulatory domain (currenly world domain (00))
But a "iw reg set US" or "iw reg set NL" does not succeed.
# iw reg get
country 00:
(2402 - 2472 @ 40), (6, 20)
(2457 - 2482 @ 40), (6, 20), PASSIVE-SCAN, NO-IBSS
(2474 - 2494 @ 20), (6, 20), NO-OFDM, PASSIVE-SCAN, NO-IBSS
(5170 - 5250 @ 80), (6, 20), PASSIVE-SCAN, NO-IBSS
(5735 - 5835 @ 80), (6, 20), PASSIVE-SCAN, NO-IBSS
(57240 - 63720 @ 2160), (N/A, 0)
# iw reg set US
# iw reg get
country 00:
(2402 - 2472 @ 40), (6, 20)
(2457 - 2482 @ 40), (6, 20), PASSIVE-SCAN, NO-IBSS
(2474 - 2494 @ 20), (6, 20), NO-OFDM, PASSIVE-SCAN, NO-IBSS
(5170 - 5250 @ 80), (6, 20), PASSIVE-SCAN, NO-IBSS
(5735 - 5835 @ 80), (6, 20), PASSIVE-SCAN, NO-IBSS
(57240 - 63720 @ 2160), (N/A, 0)
The only thing is this message in dmesg:
"cfg80211: Pending regulatory request, waiting for it to be processed...".
I did enable some of the kernel wifi debug options, but there is no error or more informatie.
But it doesn't get set as you can see above.
Attached:
dmesg.txt complete dmesg
iw-info.txt output of "iw phy0 info"

Take the phy out of reset explicitly during system resume to avoid
losing network connectivity.

A Davicom application note for the DM9000 network device recommends
performing software reset twice to correctly initialise the device.
Without this reset some devices fail to initialise correctly on
system startup.

Some of the changes introduced in commit 6741f40 (DM9000B: driver
initialization upgrade) break functionality on DM9000A
(error message during NFS boot: "dm9000 dm9000.0: eth0: link down")
Since the changes were meant to serve only DM9000B, make them
dependent on the chip type.

* PROBLEM: GRE forwarding not working with 3.10.x, WCCPv2 and Cisco 7200 Router showing IP0 bad-hlen 4 in tcpdump
From: Peter Schmitt @ 2013-10-16 8:35 UTC (permalink / raw)
To: netdev@vger.kernel.org
Hi,
I have a setup with the current kernel (3.10.16) and can't get WCCPv2 to work using GRE since kernel 3.10.x. With 3.9.x everything was working fine.
My setup is simple with three boxes included:
Client (10.111.111.222/24) -- (10.111.111.1/24) Cisco 7200 (192.168.180.113/24) -- Internet Gateway
(192.168.234.1/30)
|
WCCPv2
|
(192.168.234.2/30)
Caching Box with Squid 2.7STABLE9 WCCPv2
On the caching box, I have the interfaces:
6: eth3 inet 192.168.234.2/30 scope global eth3\ valid_lft forever preferred_lft forever
22: wccp104102 inet 192.168.234.2/32 scope global wccp104102\ valid_lft forever preferred_lft forever
The WCCP handshake is established and I can see messages on the Cisco Router:
*Oct 14 10:44:09.487: %WCCP-5-SERVICEFOUND: Service 80 acquired on WCCP client 192.168.234.2
*Oct 14 10:44:09.495: %WCCP-5-SERVICEFOUND: Service 90 acquired on WCCP client 192.168.234.2
When the client now starts a request, it gets connection timeouts:
>wget google.com
--2013-10-14 13:53:30-- http://google.com/
Resolving google.com (google.com)... 173.194.70.113, 173.194.70.100, 173.194.70.138, ...

Connecting to google.com (google.com)|173.194.70.100|:80... failed: Connection timed out.
...
A tcpdump on the Caching Box reveals the following:
