* [PATCH] atheros: define a common priv struct
From: Luis R. Rodriguez @ 2009-09-28 6:54 UTC (permalink / raw)
To: linville; +Cc: linux-wireless, devel, ath9k-devel, Luis R. Rodriguez
hw code should never use private driver data, but
sometimes we need a backpointer so just stuff it on
the common ath struct.

With this and some changes to ath9k_htc we can now start
talking to the target on ar9271. I'll synch up ath9k_htc
git tree with these changes, if you compile your kernel
with all pending patches + this one you should be able
to start playing with ath9k_htc -- oh and a new firmware
was needed, seems I had a dud firmware file. I'll update
that soon also on the athfw2lnx.git tree:

Both machines boot (and do wireless) correctly with your NETDEV_PRE_INIT
hunk placed just after the ndo_init block, instead of just before where
you placed it. That's i386 kernels on both.
But curiouser and curiouser... the laptop can do 64-bit, so I built
my 64-bit kernel, and went through the motions to reproduce the
early boot crash with the patch as you had it: but the x86_64 kernel
boots (and does wireless) correctly with the NETDEV_PRE_INIT hunk
just where you placed it, before the ndo_init block.
Perhaps there's a difference in the 32- and 64-bit startup sequence
with respect to notifiers; or perhaps your change tickles another bug.
I don't know, I'm turning off now.

OK the reason seems to be netboot. Yeah the only fix for distros who want
this on the initramfs is to update it after a compat-wireless package is
installed. I suppose we can add a hook to compat-wireless for each distro.
I'm only familiar with Ubuntu way of doing this so if people are interested
in other distros you'll need to point/test how to do this on there.
Please try this patch against compat-wireless: (also attached)

This 2/2 patch does indeed work: many thanks. But...

... the 1/2 patch has a couple of problems.
The trivial problem is that include/linux/notifier.h in Linus's git has
#define NETDEV_PRE_UP 0x000D
#define NETDEV_BONDING_OLDTYPE 0x000E
#define NETDEV_BONDING_NEWTYPE 0x000F
So it rejects the patch you posted: I changed it to add
#define NETDEV_PRE_INIT 0x0010
just after the NETDEV_BONDING_NEWTYPE line.
The more serious problem is that it stops both my machines from booting,
too early for framebuffer to show any messages, but vga=normal shows a
long stacktrace scrolling offscreen, with some notifier stuff in there.
I've experimented by moving your NETDEV_PRE_INIT hunk later in the
sequence, just before the netdev_initialize_kobject(dev) (so I also
changed the "goto out" to "goto err_uninit"): both* machines then boot
correctly, and this mail leaves me wirelessly.
I'll now experiment to see how early I can move that hunk.

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.
