Hello,
I have also tested the rt73usb which is included in the new 2.6.31 kernel (modinfo rt73usb gives the version "2.3.0"), in mode Master, using hostapd (version 0.6.9) and it works OK.
Regards,

The rfkill utility isn't generally useful to normal users, so move it to
/sbin with other system management executables.

Looks like the ibss code is trying to use more space in skb than it
allocated. It thus does not seem specific to iwl3945. I am not familiar
with that code, but it looks that the skb allocation in
ieee80211_ibss_join does not accommodate the ibss probe response that is
inserted in __ieee80211_sta_join_ibss. I hope that Johannes can guide us
here.

* [PATCH 2.6.32-rc2] ar9170: fix bug in iq-auto calibration value calculation
From: Christian Lamparter @ 2009-09-29 18:47 UTC (permalink / raw)
To: linux-wireless; +Cc: linville, Andrew Morton, Joerg Albert, David S. Miller
This patch fixes a embarrassing bug which was introduced by:
"[PATCH] ar9170: implement frequency calibration for one-stage/openfw"
The phy_data variable initialization has to done outside the for-loop
scope. This is because the for-loop uses u32 phy_data variable more
like a 4-byte field. But in each run only a single byte is calculated.
Therefore phy_data content needs to stay the same for at least 3 more
iterations, before the complete set can be uploaded.

* SME warning on 2.6.32-rc<bleh>
From: Luis R. Rodriguez @ 2009-09-29 19:24 UTC (permalink / raw)
To: linux-wireless
I believe the problem comes from the assumption from cfg80211 that
previous deauthentications would have gone through before we run
__cfg80211_disconnected() and are using wext or nl80211
connec/disconnectt. Under certain conditions (clearly not known yet)
this is not true and we'll end up asking mac80211 to deauthenticate us
from a BSS we already deauthenticated to end end up with an -ENOLINK
on our mac80211 cfg80211 deauth ops. It seems this race was expected
all along on mac80211 ieee80211_mgd_deauth():
/*
* cfg80211 should catch this ... but it's racy since
* we can receive a deauth frame, process it, hand it
* to cfg80211 while that's in a locked section already
* trying to tell us that the user wants to disconnect.
*/
if (!bssid) {
mutex_unlock(&ifmgd->mtx);
return -ENOLINK;
}
So it seems we do need to address that race but I'm not yet sure how.
Here is a warning from the latest wireless-testing. Unfortunately I
cannot reproduce in a systematic way, I've tried even different boot
configuration (mem=300M) and CPU pegged at 800 MHz thinking the race
occurs when mac80211 takes its sweet time deathenticating but that
wasn't the case.

Oliver,
Are you going to send this patch to Dave? If you want me to carry
it instead, please resend it with a proper changelog including a
Signed-off-by line. For that matter, Dave will most certainly want
that as well...
Thanks!

Seems to me that it's kinda useful, it should be possible for most users
to use the event and query interface if the /dev/rfkill permissions are
set up correctly.

Sure, but (just like ip, ifconfig, or iwconfig) nothing stops people
from using them in /sbin or /usr/sbin. It is just a convention for
tools that are more for system management than for day-to-day use.
Hopefully most people will stick with NM or whatever and may stay
completely unaware of the rfkill utility. :-)

So are you going to send an iw patch too? :-)
FWIW I like tools in bin/ since the default paths on most systems for
users don't include sbin/.

* [PATCH] wext: refactor
From: Johannes Berg @ 2009-09-29 21:27 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless
Refactor wext to
* split out iwpriv handling
* split out iwspy handling
* split out procfs support
* allow cfg80211 to have wireless extensions compat code
w/o CONFIG_WIRELESS_EXT
After this, drivers need to
- select WIRELESS_EXT - for wext support
- select WEXT_PRIV - for iwpriv support
- select WEXT_SPY - for iwspy support
except cfg80211 -- which gets new hooks in wext-core.c
and can then get wext handlers without CONFIG_WIRELESS_EXT.
Wireless extensions procfs support is auto-selected
based on PROC_FS and anything that requires the wext core
(i.e. WIRELESS_EXT or CFG80211_WEXT).
Signed-off-by: Johannes Berg <johannes@sipsolutions.net>
---
No comments received, so I guess it's good to go. Not for 2.6.32, of
course. Now all out-of-tree wext drivers need to build the kernel with a
wext driver enabled to get wext <insert manic laugh here>

-/************************** DOCUMENTATION **************************/
-/*
- * API definition :
- * --------------
- * See <linux/wireless.h> for details of the APIs and the rest.
- *
- * History :
- * -------
- *
- * v1 - 5.12.01 - Jean II
- * o Created this file.
- *
- * v2 - 13.12.01 - Jean II
- * o Move /proc/net/wireless stuff from net/core/dev.c to here
- * o Make Wireless Extension IOCTLs go through here
- * o Added iw_handler handling ;-)
- * o Added standard ioctl description
- * o Initial dumb commit strategy based on orinoco.c
- *
- * v3 - 19.12.01 - Jean II
- * o Make sure we don't go out of standard_ioctl[] in ioctl_standard_call
- * o Add event dispatcher function
- * o Add event description
- * o Propagate events as rtnetlink IFLA_WIRELESS option
- * o Generate event on selected SET requests
- *
- * v4 - 18.04.02 - Jean II
- * o Fix stupid off by one in iw_ioctl_description : IW_ESSID_MAX_SIZE + 1
- *
- * v5 - 21.06.02 - Jean II
- * o Add IW_PRIV_TYPE_ADDR in priv_type_size (+cleanup)
- * o Reshuffle IW_HEADER_TYPE_XXX to map IW_PRIV_TYPE_XXX changes
- * o Add IWEVCUSTOM for driver specific event/scanning token
- * o Turn on WE_STRICT_WRITE by default + kernel warning
- * o Fix WE_STRICT_WRITE in ioctl_export_private() (32 => iw_num)
- * o Fix off-by-one in test (extra_size <= IFNAMSIZ)
- *
- * v6 - 9.01.03 - Jean II
- * o Add common spy support : iw_handler_set_spy(), wireless_spy_update()
- * o Add enhanced spy support : iw_handler_set_thrspy() and event.
- * o Add WIRELESS_EXT version display in /proc/net/wireless
- *
- * v6 - 18.06.04 - Jean II
- * o Change get_spydata() method for added safety
- * o Remove spy #ifdef, they are always on -> cleaner code
- * o Allow any size GET request if user specifies length > max
- * and if request has IW_DESCR_FLAG_NOMAX flag or is SIOCGIWPRIV
- * o Start migrating get_wireless_stats to struct iw_handler_def
- * o Add wmb() in iw_handler_set_spy() for non-coherent archs/cpus
- * Based on patch from Pavel Roskin <proski@gnu.org> :
- * o Fix kernel data leak to user space in private handler handling
- *
- * v7 - 18.3.05 - Jean II
- * o Remove (struct iw_point *)->pointer from events and streams
- * o Remove spy_offset from struct iw_handler_def
- * o Start deprecating dev->get_wireless_stats, output a warning
- * o If IW_QUAL_DBM is set, show dBm values in /proc/net/wireless
- * o Don't lose INVALID/DBM flags when clearing UPDATED flags (iwstats)
- *
- * v8 - 17.02.06 - Jean II
- * o RtNetlink requests support (SET/GET)
- *
- * v8b - 03.08.06 - Herbert Xu
- * o Fix Wireless Event locking issues.
- *
- * v9 - 14.3.06 - Jean II
- * o Change length in ESSID and NICK to strlen() instead of strlen()+1
- * o Make standard_ioctl_num and standard_event_num unsigned
- * o Remove (struct net_device *)->get_wireless_stats()
- *
- * v10 - 16.3.07 - Jean II
- * o Prevent leaking of kernel space in stream on 64 bits.

It's not right to do something here when returning an
error, and hostapd should never have relied on it as
it only fixes up a small part of the problem anyway.

Hello,
it was a pain with my Kernel 2.6.27.29 I now updated to kernel 2.6.31-44 (from
openSUSE) and voila, it now works like a charm! I compiled the bleeding edge
compat-wireless and it just works fine now! As I initially suspected, 2.6.27
only made trouble.

While it's a good skill, don't waste your time. You're running opensuse,
I suppose, and having the same problem as Hugh:

Rafael: I'm pretty sure this (14272) is a dupe of 14263.
Heinz: please try a net-2.6 tree, or wait a couple of days until it's

^ permalink raw reply
* VLAN traffic appearing on the wrong iface
From: Blaž Bačnik @ 2009-09-30 0:54 UTC (permalink / raw)
To: linux-wireless
I use RADIUS-assigned vlans with my AP. Hostapd reports vlan change
during authentication and the station appears on correct vlan
according to "iw dev ... station dump". But actual packets keep coming
in on the default interface (wlan0), not the vlan one (eg. wlan0.2).
Moreover, I am able to ping this interface's (wlan0) IP address from
the station, even though "iw dev wlan0 station dump" does not list it.
I also tried taking RADIUS out of the loop, so I used hostapd's
"accept_mac_file" with specified vlan and I think I might have found
another bug. After applying the patch below (for I believe a rather
obvious typo), kernel started oopsing and I gave up. If needed, I can
provide config files for either hostapd or freeradius server, though
it looks like this is a driver problem.
Best regards,
Blaz
