you are beating me to it. I can only second that this is a good idea for
the dev type assignment. Once Dave acks this I can sent a rebased patch
for the dev type stuff for WiFi.

Thanks for letting me know - I had a better thought at that (or
rather, a big bundle where it came from) - It probably worked around
some bug in 2.22 which has since been fixed. I haven't heard from the
person where this came from why he did what he did, but just as well,
I guess. It served a purpose during the 2.22 period.

The GSoC student fell off from the face of the earth without even
notice so the project was never finished. The project is up for grabs

* [PATCH 2/2] cfg80211: fix wireless handlers assignment
From: Johannes Berg @ 2009-09-27 18:27 UTC (permalink / raw)
To: netdev; +Cc: linux-wireless, Hugh Dickins
The point we assign dev->wireless_handlers at is too
late, we need to do that before netdev_register_kobject()
gets called, so use the new NETDEV_PRE_INIT notifier.
The result of adding wireless_handlers too late is the
disappearance of /sys/class/net/wlan0/wireless which a
bunch of distro scripts still require.

Alright, I'll take back my NACK then, just thought it'd be easier to do
the cleanup in the same patch but I can also do it separately.

From: Johannes Berg @ 2009-09-27 18:26 UTC (permalink / raw)
To: netdev; +Cc: linux-wireless
For various purposes including a wireless extensions
bugfix, we need to hook into the netdev creation at
a point before netdev_register_kobject(). It seems
more generic, however, to have it even earlier. This
will also ease doing the dev type assignment that
Marcel was working on generically.

I've a different problem with wireless that Johannes is investigating
for me on linux-wireless; but here's a patch that he pointed me to
along the way, didn't help my issue but I expect it will help yours...
Subject: cfg80211: don't set privacy w/o key
When wpa_supplicant is used to connect to open networks,
it causes the wdev->wext.keys to point to key memory, but
that key memory is all empty. Only use privacy when there
is a default key to be used.

All:
I have a large group that uses the ssb module along with the Broadcom
4318, in a CF form factor. If the CF card is inserted before boot, and
the ssb module is not in the initrd process, the laptops lock up and do
not become operational. The solution to this problem is/was adding the
ssb.ko to the initrd process. So I agree with Luis on this, the ssb
module will have to be added/updated to the initrd process. As for PCI
operations, I don't know, but for PCMCIA operations ssb.ko has to be
added and/or updated. Anytime I am testing new releases of b43, I run
"update-initramfs -u" to update the ssb module. (Sometimes you can do a
rmmod ssb and rmmod b43, and then modprobe them back in. - This saves a
reboot)

* Unable to create an 802.11s mesh using compat-wireless-2009-09-27
From: Simon Raffeiner @ 2009-09-27 13:41 UTC (permalink / raw)
To: linux-wireless
Hello List,
I built todays compat-wireless (compat-wireless-2009-09-27) on two different
Ubuntu machines:
- kernel 2.6.28-15-generic i686 using rt73usb
- kernel 2.6.31-11-generic x86_64 using ath5k (AR2425)
and tried to create an 802.11s Mesh following the HOWTO - unsuccessfully:
root@ion:/home/sturmflut# export MESH_IFACE=mesh
root@ion:/home/sturmflut# export MESH_ID=test
root@ion:/home/sturmflut# iw dev wlan0 interface add $MESH_IFACE type mp
mesh_id $MESH_ID
root@ion:/home/sturmflut# ifconfig -a | grep mesh
mesh Link encap:Ethernet HWaddr 00:22:75:50:13:c2
root@ion:/home/sturmflut# ifconfig $MESH_IFACE up
SIOCSIFFLAGS: Name not unique on network
if I remove wlan0 the mesh device can be brought up through ifconfig:
root@ion:/home/sturmflut# iw dev wlan0 del
root@ion:/home/sturmflut# ifconfig $MESH_IFACE up
The strange thing is that iwconfig lists the interface as Mode "Auto"
immediately after it is added:
root@ion:/home/sturmflut# iwconfig mesh
mesh IEEE 802.11bg Mode:Auto Tx-Power=11 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:on
and falls back to "Managed" after about five seconds:
root@ion:/home/sturmflut# iwconfig mesh
mesh IEEE 802.11bg Mode:Managed Access Point: Not-Associated
Tx-Power=11 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on
Symptoms are identical on both machines. I remember this working some weeks
ago, at least using the ath5k driver, and without any "Name not unique on
network" errors.
I could try with a full wireless-testing.git checkout but I doubt anything
will change, Ubuntus 2.6.31-11-generic is quite recent and all relevant
modules should have been overwritten by those in compat-wireless.

Hi,
With todays git my laptop fails to associate with my access point.
Bisection points to the commit below, and reverting this one commit on
the HEAD of tree also fixes the issue, so I'm pretty confident that this
commit is to blame.
I have a 4965 wifi card in my laptop, and the network I'm trying to
connect to has no encryption. I'm running Fedora 11 as OS.
I would like to kindly request for this commit to be reverted until a
more permanent solution is found (I'm happy to test any patches)..

cfg80211: don't overwrite privacy setting
When cfg80211 is instructed to connect, it always
uses the default WEP key for the privacy setting,
which clearly is wrong when using wpa_supplicant.
Don't overwrite the setting, and rely on it being
false when wpa_supplicant is not running, instead
set it to true when we have keys.

Curious. I found the problem, but maybe nobody else complaining before
you means we can get rid of CONFIG_WIRELESS_EXT_SYSFS quicker than I
thought ;)
Will post a fix later today.

* [RFC/RFT v4] wext: refactor
From: Johannes Berg @ 2009-09-27 11:13 UTC (permalink / raw)
To: linux-wireless
In-Reply-To: <1253967589.5122.11.camel@johannes.local>
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).

-/************************** 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.

That appears to be the problem, though I wonder why that is. I'll look
into it.

I suppose (together with some of the newly added printk you mentioned
could be removed in the final version) the dmesg messages are somewhat
confusing, because as a user, I would rather have a deauth message
that's actually associated with a user action (e.g. if I switch AP or
rfkill). Is it possible to distinguish situation where a user action
is involved versus one that isn't? or is the distinction between any
consequence of 'user-action' vs wpa_supplicant doing-it-on-its-own too
much buried down in the layers?

Yes - I meant Albert - wpa_spplicant runs directly probably behaves a
little differently from NM starting/stopping it.

* [PATCH] mac80211_hwsim: Fix initial beacon timer configuration
From: Jouni Malinen @ 2009-09-26 19:30 UTC (permalink / raw)
To: John W. Linville; +Cc: linux-wireless
mac80211_hwsim does not start transmitting Beacon frames when hostapd
is started for the first time and restarting hostapd fixes this. The
issue is caused by the config() handler not being able to start
beacon_timer when beacon interval is not yet known and
bss_info_changed() handler not starting the timer. This can be fixed by
making the bss_info_changed() update the timer.

That should only be showing up if virtual wiphys are used. In this case,
it should not really be showing up and is likely indicating a bug
somewhere (ath9k or mac80211). I don't know how to reproduce this
easily, so I have not looked into more details yet. It would be
interesting to add printk calls into ath9k_sw_scan_start() and
ath9k_sw_scan_complete() just after the mutex_lock() call to figure out
whether mac80211 ends up calling sw_scan_start() driver handler twice in
a row which would be one possible way to get this triggered. The other
way to hit this would be if ath9k were to somehow not update aphy->state
correctly when the scan has been completed.

* [PATCH 3/9] Add bound checks in wext for copy_from_user
From: Arjan van de Ven @ 2009-09-26 18:51 UTC (permalink / raw)
To: Arjan van de Ven; +Cc: linux-kernel, torvalds, mingo, linux-wireless
In-Reply-To: <20090926204951.424e567e@infradead.org>
From: Arjan van de Ven <arjan@linux.intel.com>
Subject: [PATCH 3/9] Add bound checks in wext for copy_from_user
CC: linux-wireless@vger.kernel.org
The wireless extensions have a copy_from_user to a local stack
array "essid", but both me and gcc have failed to find where
the bounds for this copy are located in the code.
This patch adds some basic sanity checks for the copy length
to make sure that we don't overflow the stack buffer.
