* [PATCH 2/2] wl12xx: configure probe-resp template according to notification
From: Guy Eilam @ 2011-10-22 13:14 UTC (permalink / raw)
To: coelho; +Cc: linux-wireless
In-Reply-To: <1319289279-21950-1-git-send-email-guy@wizery.com>
When operating in AP-mode, replace probe-response template when a
notification is recieved from mac80211. We preserve the "legacy" way of
configuring a probe-response according to beacon for IBSS mode and for
versions of hostapd that do not support this feature.

This is really just historic -- nobody has so far cared about TX power
enough to clean up the APIs for it etc. The distinction between
"automatic", "fixed" and "limited" (auto <= some value) is also not
really done very well here.

and this seems unnecessary -- why not just put a u32 value into struct

Hm, also: should we call this WPS or WSC, and do we need to distinguish
WPS and WPS2? My AP mode patch called it WSC in a different context but
I can change, we just should be consistent.

Oh, and probably a regular WIPHY flag that indicates whether the
attribute should be added at all so that it can also be 0 but present
(presence with 0 value indicates something other than not present).

* [PATCH] nl80211: clean up genlmsg_end uses
From: Johannes Berg @ 2011-10-22 17:05 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless
From: Johannes Berg <johannes.berg@intel.com>
genlmsg_end() cannot fail, it just returns the length
of the message. Thus, error handling for it is useless.
While removing it, I also noticed a useless variable
and removed this it as well.

When this is not supported a -EOPNOTSUPP should be returned.
A 0 return means that it is supported.
I now see that I have a small mistake in the patch regarding this.
The check should be (res >= 0) and not (!res).
I'll fix it.

Yeah but if you add a wiphy flag and the bits into struct wiphy, then
you can save the function pointer which seems nicer?

You're absolutely right.
I'll send another version of the patch that will have a flag and
bitmap in the wiphy struct.

Also I believe that means you don't need patch 2 at all so that's kinda
nice :-)

Oops I should have pointed that out before -- that's not valid
kernel-doc.
Also, maybe this should say how it'll be supported (i.e. by passing the
frame up for userspace to reply to, I think?)

From: Arik Nemtsov @ 2011-10-23 6:21 UTC (permalink / raw)

Some cards can generate CCMP IVs in HW, but require the space for the IV
to be pre-allocated in the frame at the correct offset. Add a key flag
that allows us to achieve this.

Hi Nico,
I see three different AP's in this log. Could you indicate what AP you
have issues with.

With the suspend/resume cycles early in the dmesg log it seems brcmsmac
gets disassoc/deauth before going to sleep. When things start to get
flaky this does not seem to happen and I see a lot of deauth reason=2 in
the log. If I am correct that would mean previousAuthNotValid. Not sure
why we see that. Will try to reproduce this tomorrow.

* [RFC] ipv6 over wireless classification issue?
From: David Täht @ 2011-10-23 10:23 UTC (permalink / raw)
To: bloat-devel, linux-wireless@vger.kernel.org
[-- Attachment #1: Type: text/plain, Size: 1932 bytes --]
After slowly working my way down from verifying the apps to ECN handling
and up from the drivers... I've been (also) slowly working on getting
wireless qos/aqms to work better, on ipv6. (I need to get to having a
spectrum analyzer or better instrumentation...) I was puzzled about dscp
marked ipv6 packets responding differently.
Perhaps this is it. I'm not making this a commit yet (untested code!)

A) Elsewhere in the stack ipv4_get_dsfield is the equivalent of the
ip_hdr(skb)->tos & 0xfc line
B) It appears ipv6_get_dsfield is safe to call from non-ipv6 enabled
systems
So my thought would be to also harmonize this with ipv4_get_dsfield...
C) And I doubt that slamming arp packets into the VI queue would be
acceptable yet (as per the ANTs discussion of a few months back, ARP,
ND, RA, RS, DHCP, and possibly DNS, ssh (marked interactive), etc might
do better in the VI queue)
(however this part of the patch is not relevant to the IPv6 issue, it's
just the patch I wanted to try)
D) Lastly, Later on in this function only dscp's first 3 bits (CS0 -
CS7) are used to classify packets into the queues, where a mildly saner
version would use a lookup table to also do sane things with the
'immediate' bit, perhaps settable via userspace from via sysfs, sysctl,
or proc.

It's a WPNT384 (Netgear), an early pre-draft-n ap.

Thanks for digging in there. I've to update my report: After another two
suspend/resume cycles, the connection works fine again:
64 bytes from 192.168.42.1: icmp_req=38950 ttl=64 time=103 ms
64 bytes from 192.168.42.1: icmp_req=38951 ttl=64 time=47.4 ms

64 bytes from 192.168.42.1: icmp_req=38956 ttl=64 time=64.8 ms
[...]
I'm watching this problem for the next time and as soon it happens
again, I'll test with other wifi devices to verify that the problem
is not within the AP.
I've attached the updated dmesg.
Cheers,

Do you mean something like IEEE80211_QOS_CTL_MESH_POWER_SAVE_LEVEL?
The first half is similar to previous constants.

Please disregard this one. The problem was with an internal patch I

* [PATCH] mac80211: Fix TDLS support validation in add_station handler
From: Jouni Malinen @ 2011-10-23 19:36 UTC (permalink / raw)
To: John W. Linville, Johannes Berg; +Cc: linux-wireless, Arik Nemtsov
We need to verify whether the command is successful before allocating
the station entry to avoid extra processing. This also fixes a memory
leak on the error path.
