Daniel Drake f2060f039e [PATCH] ieee80211: Make ieee80211_rx_any usable
ieee80211_rx_any is new to 2.6.18-rc1, even though it appears this function
was never completed:

http://lists.sipsolutions.net/pipermail/softmac-dev/2006-February/000103.html

This patch changes ieee80211_rx_any to always claim the skb, which avoids
further driver complexity and the possibility of leaking management frames.
It also exports the function so that people can actually use it.

Daniel Drake 5acd0c4153 [PATCH] softmac: ERP handling and driver-level notifications
This patch implements ERP handling in softmac so that the drivers can support
protection and preambles properly.

I added a new struct, ieee80211softmac_bss_info, which is used for
BSS-dependent variables like these.

A new hook has been added (bssinfo_change), which allows the drivers to be
notified when anything in bssinfo changes.

I modified the txrates_change API to match the bssinfo_change API. The
existing one is a little messy and the usefulness of providing the old rates
is questionable (and can be implemented at driver level if really necessary).
No drivers are using this API (yet), so this should be safe.

Daniel Drake d8e2be90d3 [PATCH] ieee80211: small ERP handling additions
This adds a flag to the ieee80211_network structure which indicates whether
the stored erp_value is valid (a check against 0 is not enough, since an ERP
of 0 is valid and very meaningful).

I also added the ERP IE bit-definitions to ieee80211.h.

This is needed by some upcoming softmac patches.

Daniel Drake 345f6b8beb [PATCH] softmac: do shared key auth in workqueue
Johann Uhrmann reported a bcm43xx crash and Michael Buesch tracked
it down to a problem with the new shared key auth code (recursive
calls into the driver)

This patch (effectively Michael's patch with a couple of small

challenge response frame from a workqueue entry.

I also removed a lone \n from the bcm43xx messages relating to
authentication mode - this small change was previously discussed but

This patch addresses the "No queue exists" messages commonly seen during
authentication and associating.  These appear due to scheduling multiple
authentication attempts on the same network.  To prevent this, I added a

I also added a check to the wx handler to see if we're connecting to a

Larry Finger 6d41e26510 [PATCH] 2.6.17 missing a call to ieee80211softmac_capabilities from ieee80211softmac_assoc_req
In commit ba9b28d19a, routine
ieee80211softmac_capabilities was added to ieee80211softmac_io.c. As
denoted by its name, it completes the capabilities IE that is
needed in the associate and reassociate requests sent to the
AP. For at least one AP, the Linksys WRT54G V5, the capabilities
field must set the 'short preamble' bit or the AP refuses to
associate. In the commit noted above, there is a call to the
new routine from ieee80211softmac_reassoc_req, but not from
ieee80211softmac_assoc_req. This patch fixes that oversight.

As noted in the subject, v2.6.17 is affected. My bcm43xx card had been
unable to associate since I was forced to buy a new AP. I finally was
able to get a packet dump and traced the problem to the capabilities
info. Although I had heard that a patch was "floating around", I had
not seen it before 2.6.17 was released. As this bug does not affect
security and I seem to have the only AP affected by it, there should
be no problem in leaving it for 2.6.18.

Daniel Drake 6ae15df16e [PATCH] softmac: Fix handling of authentication failure
My router blew up earlier, but exhibited some interesting behaviour during
its dying moments. It was broadcasting beacons but wouldn't respond to
any authentication requests.

I noticed that softmac wasn't playing nice with this, as I couldn't make it try
to connect to other networks after it had timed out authenticating to my ill
router.

To resolve this, I modified the softmac event/notify API to pass the event
code to the callback, so that callbacks being notified from
IEEE80211SOFTMAC_EVENT_ANY masks can make some judgement. In this case, the
ieee80211softmac_assoc callback needs to make a decision based upon whether
the association passed or failed.

Daniel Drake 76ea4c7f4c [PATCH] softmac: complete shared key authentication
This patch finishes of the partially-complete shared key authentication
implementation in softmac.

The complication here is that we need to encrypt a management frame during
the authentication process. I don't think there are any other scenarios where
this would have to happen.

To get around this without causing too many headaches, we decided to just use
software encryption for this frame. The softmac config option now selects
IEEE80211_CRYPT_WEP so that we can ensure this available. This also involved
a modification to some otherwise unused ieee80211 API.

Daniel Drake 8462fe3cd9 [PATCH] softmac: suggest per-frame-type TX rate
This patch is the first step towards rate control inside softmac.

The txrates substructure has been extended to provide
different fields for different types of packets (management/data,
unicast/multicast). These fields are updated on association to values
compatible with the access point we are associating to.

Drivers can then use the new ieee80211softmac_suggest_txrate() function
call when deciding which rate to transmit each frame at. This is
immensely useful for ZD1211, and bcm can use it too.

The user can still specify a rate through iwconfig, which is matched
for all transmissions (assuming the rate they have specified is in
the rate set required by the AP).

At a later date, we can incorporate automatic rate management into
the ieee80211softmac_recalc_txrates() function.

This patch also removes the mcast_fallback field. Sam Leffler pointed
out that this field is meaningless, because no driver will ever be
retransmitting mcast frames (they are not acked).

Daniel Drake d57336e3f2 [PATCH] softmac: make non-operational after being stopped
zd1211 with softmac and wpa_supplicant revealed an issue with softmac
and the use of workqueues. Some of the work functions actually
reschedule themselves, so this meant that there could still be
pending work after flush_scheduled_work() had been called during
ieee80211softmac_stop().

This patch introduces a "running" flag which is used to ensure that
rescheduling does not happen in this situation.

I also used this flag to ensure that softmac's hooks into ieee80211 are
non-operational once the stop operation has been started. This simply
makes softmac a little more robust, because I could crash it easily
by receiving frames in the short timeframe after shutting down softmac
and before turning off the ZD1211 radio. (ZD1211 is now fixed as well!)

Michael Buesch 9b0b4d8ae8 [PATCH] softmac: fix spinlock recursion on reassoc
This fixes a spinlock recursion on receiving a reassoc request.

On reassoc, the softmac calls back into the driver. This results in a
driver lock recursion. This schedules the assoc workqueue, instead
of calling it directly.

Probably, we should defer the _whole_ management frame processing
to a tasklet or workqueue, because it does several callbacks into the driver.
That is dangerous.

This fix should go into linus's tree, before 2.6.17 is released, because it
is remote exploitable (DoS by crash).

We don't make much of an attempt to fall back to lower rates, and 54M
just isn't reliable enough for many people. In fact, it's not clear we

This patch makes us default to 11M, which ought to work for most people.
When we actually handle dynamic rate adjustment, we can reconsider the
defaults -- but even then, probably it makes as much sense to start at
11M and adjust it upwards as it does to start at 54M and reduce it.

Larry Finger d94606e058 [PATCH] Minor (janitorial) change to ieee80211
The attached patch removes a potential problem from ieee80211_wx.c, by changing the name of routine
ipw2100_translate_scan to ieee80211_translate_scan. The problem is minor as the routine is declared
static; however, if it were made global, it would pollute the namespace.

James Ketrenos f44349f221 [PATCH] ieee80211: Don't update network statistics from off-channel packets.
This patch fixes a problem in the ieee80211 probe response and beacon
reception code that would use the packet statistics for a network even
if they were received on a channel other than that which the network
exists on.

This causes a problem in overlapping channels where, for example, a
strong AP on channel 2 could have its beacons received on channels 1 and
3, but at much lower signal levels.  If scanning was done sequentially,
this means the beacon received on channel 3 would update the AP's signal
level as being much lower than it really is, which subsequently could
cause that AP to be passed over and an alternate AP selected.

Pete Zaitcev 07981aa43f [PATCH] ieee80211_geo.c: remove frivolous BUG_ON's
I have come to consider BUG_ON generally harmful. The idea of an assert is
to prevent a program to execute past a point where its state is known
erroneous, thus preventing it from dealing more damage to the data
(or hiding the traces of malfunction). The problem is, in kernel this harm
has to be balanced against the harm of forced reboot.

The last straw was our softmac tree, where "iwlist eth1 scan" causes
a lockup. It is absolutely frivolus and provides no advantages a normal
assert has to provide. In fact, doing this impedes debugging.

this DFS.  All STAs should send the DFS as one of the information
element in the beacon they are scheduled to send (if possible) in
the future.

Since the ibss_dfs has variable length, it must be allocated
dynamically. ieee80211_network_reset() is added to clear the ibss_dfs
field. ieee80211_network_free() is also updated to free the ibss_dfs
field if it is not NULL.

Johannes Berg a4bf26f30e [PATCH] ieee80211: enable hw wep where host has to build IV
This patch fixes some of the ieee80211 crypto related code so that
instead of having the host fully do crypto operations, the host_build_iv
flag works properly (for WEP in this patch) which, if turned on,
requires the hardware to do all crypto operations, but the ieee80211
layer builds the IV. The hardware also has to build the ICV.

Previously, the host_build_iv flag couldn't be used at all for WEP, and
not alone (with both host_decrypt and host_encrypt disabled) because the
crypto algorithm wasn't assigned. This is also fixed.

I have tested this patch both in host crypto mode and in hw crypto mode
(with the Broadcom chipset).

Without this patch, if you try and use a key that has not been
configured, for example:

% iwconfig eth1 key deadbeef00 [2]

without having configured key [1], then the active key will still be
[1], but privacy will now be enabled.  Transmission of a packet in this

Per the conversations with folks at OLS, the QoS layer in 802.11
drivers can now result in NETDEV_TX_BUSY being returned when the queue
a packet is targetted for is full.

To implement this, ieee80211_xmit will now call the driver's
is_queue_full to determine if the current priority queue is full.  If
so, NETDEV_TX_BUSY is returned to the kernel and no processing is done
on the frame.

committer James Ketrenos <jketreno@linux.intel.com> 1127313183 -0500

Fix TKIP, repeated fragmentation problem, and payload_size reporting

1. TKIP encryption
    Originally, TKIP encryption issues msdu + mpdu encryption on every
    fragment. Change the behavior to msdu encryption on the whole
    packet, then mpdu encryption on every fragment.

2. Avoid repeated fragmentation when !host_encrypt.
    We only need do fragmentation when using host encryption. Otherwise
    we only need pass the whole packet to driver, letting driver do the
    fragmentation.

3. change the txb->payload_size to correct value
    FW will use this value to determine whether to do fragmentation. If
    we pass the wrong value, fw may cut on the wrong bound which will
    make decryption fail when we do host encryption.

NOTE:  This requires changing drivers (hostap) that have
extra_prefix_len used within them (structure member name change).

Export a new function ieee80211_crypt_quiescing from ieee80211. Device
drivers call it to make the host crypto stack enter the quiescence
state, which means "process existing requests, but don't accept new
ones". This is usually called during a driver's host crypto data
structure free (module unload) path.

Fixed a kernel oops on module unload by adding spin lock protection to
ieee80211's crypt handlers (thanks to Zhu Yi)

Modified scan result logic to report WPA and RSN IEs if set (vs.being
based on wpa_enabled)

Added ieee80211_device as the first parameter to the crypt init()
method.  TKIP modified to use that structure for determining whether to
countermeasures are active.
