Well, it can be used to try to make legacy stations not attempt
connection, but no guarantees on them actually checking whether they
support all the "basic rates".. For example, where is mac80211 (or
wpa_supplicant) doing that check? ;-)

This looks a bit odd since the BSS_MEMBERSHIP_SELECTOR is not exactly
same as basic rate indicator even through they share the same bit. We
used to have the magic 0x80 value here which could actually look less
confusing than the mixing of basic and BSS membership terms.

While this is not really introduced by this patch, this looks quite
bogus since the higher-than-11Mbps is then used to figure out whether
this was a 802.11g network. That is not correct since a network with a
single supported rate 6 Mbps should also get that behavior.. More robust
mechanism would be to check for any OFDM rate being listed.

Yay for getting rid of the duplicated loop :-).

Actually, you have already implemented the check in hostapd :)
commit 2944824315b7c74838c551ef08c9843e02de1d46
Author: Jouni Malinen <jouni.malinen@atheros.com>
Date: Wed Feb 9 15:08:47 2011 +0200
line 682:
if (hapd->iconf->ieee80211n && hapd->iconf->require_ht &&
!(sta->flags & WLAN_STA_HT)) {
hostapd_logger(hapd, sta->addr, HOSTAPD_MODULE_IEEE80211,
HOSTAPD_LEVEL_INFO, "Station does not support "
"mandatory HT PHY - reject association");
return WLAN_STATUS_ASSOC_DENIED_NO_HT;
}
so if a legacy station decides to join a require_ht = 1 BSS
then the AP will refuse it with WLAN_STATUS_ASSOC_DENIED_NO_HT
and the wpa_supp client will blacklist the AP because of that
and it will choose a different AP for the next try.

So, what's the exact difference between then BasicRate and a MembershipRate
in this context then? Is a rate called "basic rate" when it's one of the
legacy e.g.: 6, 12, 24 Mbit rates [And likewise: is a rate called a MembershipRate
when only in the magic 127 HT PHY case?]

Also, there's 22mbit 8-PSK PBCC [I think mwl8k supports it and some TI
stuff could support it as well]. The check is questionable, but fixing
it may no be trivial either. [Anyway, it's a bit outside the scope and
requires another patch]

* [PATCH] libertas: fix changing interface type when interface is down
From: Daniel Drake @ 2011-10-14 11:05 UTC (permalink / raw)
To: linville, dcbw; +Cc: linux-wireless, libertas-dev
The recent changes to only power the device when the interface up
introduced a bug: changing interface type, legal when the interface
is down, performs device I/O.
Fix this functionality by validating and recording the interface
type when the change is requested, but only applying the change
if/when the interface is brought up.

* How to create library module with callbacks?
From: Rafał Miłecki @ 2011-10-14 13:21 UTC (permalink / raw)
To: linux-wireless
I want to create module library, which will handle PHY operations on
Broadcom card. For most of the time, I'm going to call library
functions from b43.
However, there are places where I need to call some (b43) driver
function from library module.
How can I handle that? Should I pass some functions pointers to the
library? Is that going to work? Or is there a better approach?
P.S.
I'm asking at linux-wireless, it's not wireless related however. I
think question is quite simple for C hackers and there is no need to
hit LKML.

Yes, that should work. All modules and the kernel live in the same
address space. But you should make sure that those pointers won't be
used if the calling module is unloaded.
In fact, b43 does it already with mac80211, ssb and bcma. See
b43_hw_ops, b43_ssb_driver and b43_bcma_driver in the code.

Hi Rafał,
It should be no different as normal drivers do. In your case I would say
b43 registers itself with phylib module and provides phylib_ops. It
could also provide the bcma_device for the 80211 core so the phylib can
use bcma directly. Whether or not phylib is still a library module when
doing so can be argued. As it does not provide a system function by
itself I tend to say it is.
I would suggest to look into mac80211 to see how it deals with the
callbacks it does into the device drivers.

* iwlagn: WARN_ON() in iwl_get_idle_rx_chain_count()
From: Michał Mirosław @ 2011-10-14 15:02 UTC (permalink / raw)
To: Intel Linux Wireless; +Cc: linux-wireless, netdev
WARN_ON() in iwl_get_idle_rx_chain_count() gets triggered on system shutdown
when WiFi card is associated to an AP. This is on kernel built from
Linus' tree, commit 37cf95162af4036b4198756a590aab8126fa2ce4 (3.1.0-rc9+).
It looks HT-related, I can't reproduce this on 802.11g network.

I'm not not sure compilers would optimize it out on little-endian
systems. Perhaps you want a define that uses this code on
big-endian systems and does nothing on little endian systems.
Also, it would be nice to have a compile-time check that size is even.
Or maybe size should be the number of 16-bit words, but then it would be
better to call the argument "count" or something like that.

In-Reply-To: <20111014151119.246288840@sipsolutions.net>

Drivers that need to drop a frame before it
can be transmitted will usually simply free
that frame. This is currently fine, but in
the future it'll be needed to tell mac80211
about this case, so add a new routine that
frees a TX skb.

To implement AP mode without monitor interfaces we
need to be able to send a deauth to stations that
send frames without being associated. Enable this
by adding a new nl80211 event for such frames that
an application can subscribe to.
