Frequent crashes on Ubuntu 12.04

Пётр Дёмин — 2013-05-25T22:36:54

Hello,

Could you, please, help me with following issue?

I'm experiencing frequent failures on my notebook with Ubuntu 12.04.
Error appears in following order:
# Wi-Fi disconnects and starts reconnecting.
# After some time (about 30 seconds), password for wi-fi network is asked.
# No matter what I enter, connection fails with same question about password.

If I uncheck "Enable Wireless" and then check it back, no networks are shown.

I attached part of syslog, written during failure.

This also might help, I hope:
$ sudo lshw | grep iwl
configuration: broadcast=yes driver=iwlwifi
driverversion=3.2.0-44-generic firmware=39.31.5.1 build 35138
ip=192.168.1.33 latency=0 link=yes multicast=yes wireless=IEEE
802.11bg

Best regards, Peter Demin.

Re: [PATCH] B43: Handle DMA RX descriptor underrun

Larry Finger — 2013-05-25T20:37:02

The patch is in wireless-testing with John's s-o-b, and in the mainline tree 
with the same annotation.

It has been working OK here, but my devices did not show underrun.

This is included in OpenWrt for ~4 weeks now and I haven't read of
anybody complaining about any new problems introduced by this patch or
something which looks like the DMA under run.
I am also for adding this to the kernel.

RE: [RFC 2/2] cfg80211: separate internal SME implementation

Kondratiev, Vladimir — 2013-05-25T15:33:00

Hi Vladimir,

This patch breaks wil6210 compilation. You shouldn't be using the
cfg80211 internal state, even if it's available to drivers for technical
reasons. Please remove the usage of wdev->sme_state from your driver,
I'd like to merge this patch that changes the internal SME
implementation in cfg80211.

johannes

Hi Johannes,

I prepared the patch, need few days to test it and I'll submit.

I have conceptual question regarding wdev private data.
Currently, drivers end up duplicating wdev's data internally. I'd say it is better to track, for example,
SME connection state once. Maybe, it is worth to provide functions to access wdev's data?

Thanks, Vladimir--

P2P Device support: how to deal with p2p_no_group_iface option

Arend van Spriel — 2013-05-25T11:23:47

Hi Jouni,

I looked into issues around hwsim p2p tests and got all but one p2p test 
passing now (test_autogo_tdls). I had to remove the p2p_no_group_iface 
option from the p2px.conf files, because otherwise it tries to change 
the P2P management interface into a P2P group interface. When using 
P2P_DEVICE and P2P management interface this is not allowed by 
mac80211_hwsim. Also for brcmfmac the P2P_DEVICE interface is dedicated 
and can only be added/deleted, but not changed. Not sure if that is true 
for iwlmvm as well.

So I would like to discuss how to deal with the p2p_no_group_iface 
option. As P2P_DEVICE is a new concept the name of the option may no 
longer match what it intends. Is the option to force all P2P operations 
to be done on a single interface, ie. wlan0 (or whatever is specified on 
the command line) and no P2P_DEVICE is to be created. Or should it 
change the interface from the command line as P2P group interface.

If we can make a decision here I can finalize the P2P_DEVICE support 
cha

[v3.10-rc2] iwlwifi regression

If iwlwifi/iwldvm are built into the kernel (no loadable modules)
following error is written to console and syslog since v3.10-rc:

[RFT/RFC 5/4] iwlegacy: unblock queues on passive channel if any frame receive

Stanislaw Gruszka — 2013-05-25T08:55:04

Currently we unblock queues (when blocked on passive channel) only if
beacon with our bssid will be received. Change that to any frame, since
firmware should allow to transmit frames on passive channel when it
receives any frame with valid CRC sum.

Re: [RFT/RFC 0/4] iwlegacy: workaround for firmware frame tx rejection

Stanislaw Gruszka — 2013-05-25T08:53:00

I prefer to unblock queues on any frame, as this allow to start

I'll add patch 5/4 which implement that.

Re: [PATCH 3/3] {nl,mac,cfg}80211: Allow user to configure basic rates for mesh

Johannes Berg — 2013-05-25T08:20:49


Heh, good question. I think it was probably copied from IBSS where you
can pick another channel? Doesn't make all that much sense for mesh I
guess, unless MBSS channel switch could cause us to use another channel?
But then presumably you should follow the basic rates from the STA
initiating the switch, or something, since mesh networks are only
compatible with the same basic rates, right?

No problem, it doesn't have to be fast. I plan to post patches to
-next (i.e. 3.11), since we have simpler workaround already applied.
