[PATCH 00/18] mac80211 cleanups and fixes

[Johannes Berg]

Hi,

Here's another series to clean up a bit including a few things that
I've been meaning to do for a long time:

 * mac80211: move ieee80211_set_freq to utils
 * mac80211: make bridge_packets a virtual interface option
 * mac80211: clean up some comments
 * mac80211: inform driver of basic rateset
 * mac80211: use nl80211 interface types

I'd been talking with Sujith about this one:

 * mac80211: share STA information with driver

and decided to just do it; as it stands it's not very useful
but I expect it to be used soon, if not we can remove the
EXPORT_SYMBOL again.

[PATCH 01/18] mac80211: move ieee80211_sta_expire

[Johannes Berg]

ieee80211_sta_expire uses the internal __sta_info_unlink
function which can become static if this function is moved
to sta_info.c.

[PATCH 02/18] mac80211: move STA timer restart

[Johannes Berg]

This I shouldn't have moved to the scan implementation, move
it back to the MLME where it belongs, to the notification.

[PATCH 03/18] mac80211: dont set REQ_RUN when scan finishes

[Johannes Berg]

The timer restart is done wrongly, we shouldn't set the REQ_RUN
bit when the scan has finished if it hadn't been set before the
scan started. If the timer fires during the scan, it will set
REQ_RUN and then we can run the work for it, if it didn't fire
then we shouldn't run its work either.

[PATCH 04/18] mac80211: split off mesh handling entirely

[Johannes Berg]

This patch splits off mesh handling from the STA/IBSS.
Unfortunately it increases mesh code size a bit, but I
think it makes things clearer. The patch also reduces
per-interface run-time memory usage.

Also clean up a few places where ifdef is not required.

[PATCH 05/18] mac80211: fix work race

[Johannes Berg]

When we stop an interface, the work on it may still be pending
or running. We do cancel the timer, but we do not currently
protect against the work struct. The race is very unlikely to
hit -- it'll happen only when the driver is using mac80211's
workqueue to run long-running tasks and the sta/mesh works are
delayed for quite a bit.

This patch fixes it by cancelling the work explicitly.

[PATCH 06/18] mac80211: fix scan vs. interface removal race

[Johannes Berg]

When we remove an interface, we can currently end up having
a pointer to it left in local->scan_sdata after it has been
set down, and then with a hardware scan the scan completion
can try to access it which is a bug. Alternatively, a scan
that started as a hardware scan may terminate as though it
was a software scan, if the timing is just right.

On SMP systems, software scan also has a similar problem,
just canceling the delayed work and setting a flag isn't
enough since it may be running concurrently; in this case
we would also never restore state of other interfaces.

This patch hopefully fixes the problems by always invoking
ieee80211_scan_completed or requiring it to be invoked by
the driver, I suspect the drivers that have ->hw_scan() are
buggy. The bug will not manifest itself unless you remove
the interface while hw-scanning which will also turn off
the hw, and then add a new interface which will be unusable
until you scan once.

[PATCH 07/18] mac80211: reorder MLME code more

[Johannes Berg]

This way all the utility functions are at the top, then the
state machine and externally callable functions are moved to
the bottom. Also clean up ieee80211_i.h a bit and add a few
comments about which functions are called from where.

[PATCH 09/18] mac80211: make bridge_packets a virtual interface option

[Johannes Berg]

The bridge_packets configuration really should be per virtual
interface (theoretically per AP/VLAN, but this is much easier);
there currently is no way to set it yet though. Also invert
the option to "NO_BRIDGE_PACKETS" so the default is to bridge.

While at it, also document the flags properly.

[PATCH 10/18] mac80211: clean up scan namespace

[Johannes Berg]

Most of the scan functions are called ieee80211_sta_scan_*
or similar, make clean it up so they are all just called
ieee80211_scan_*.

a comment about implementing fragments better, we really
have better things to do.

[PATCH 13/18] mac80211: use nl80211 interface types

[Johannes Berg]

There's really no reason for mac80211 to be using its
own interface type defines. Use the nl80211 types and
simplify the configuration code a bit: there's no need
to translate them any more now.

[PATCH 14/18] mac80211: move regular interface handling

[Johannes Berg]

Move the code to handle regular interfaces out of main.c and
into iface.c, keep only the master interface stuff in main.c.

[PATCH 15/18] mac80211: warn on some invalid vlan operations

[Johannes Berg]

These should never happen, but better warn about them than
crashing a driver, the fact that they never happen is rather
subtle throughout mac80211.

[PATCH 16/18] mac80211 hwsim: verify vif pointers

[Johannes Berg]

mac80211-hwsim is a debugging tool for mac80211, and as such
it can very well verify that mac80211 isn't passing junk to
drivers, especially the vif pointer is prone to this because
for vlan interfaces the AP interface pointer needs to be passed.
This makes mac80211-hwsim add a magic cookie to the private vif
area and verify it whenever an operation is called that gets a
vif pointer.

[PATCH 17/18] mac80211: share STA information with driver

[Johannes Berg]

This patch changes mac80211 to share some more data about
stations with drivers. Should help iwlwifi and ath9k when
 they get around to updating, and might also help with
implementing rate control algorithms without internals.

[PATCH 18/18] mac80211 hwsim: verify sta pointers

[Johannes Berg]

In analogy with the previous patch to make mac80211-hwsim
verify that the virtual interface pointers are correct,
this makes it very that it knows about all station structs.

[PATCH 19/18] mac80211: small rate control changes

[Johannes Berg]

This patch fixes mac80211 to not rely on the rate control
algorithm to update sta->tx_retry_failed and sta->tx_retry_count
(even if we don't currently use them), removes a number of
completely unused values we don't even show in debugfs and
changes the code in ieee80211_tx_status() to not look up the
sta_info repeatedly.

The only behaviour change here would be not calling the rate
control function rate_control_tx_status() when no sta_info is
found, but all rate control algorithms ignore such calls anyway.

Signed-off-by: Johannes Berg <johannes@sipsolutions.net>
---
Now we can also change it to pass in the actual rate control information
to the algorithm, saving all the lookups there and the cross-dir header
inclusion! :)

If its a debugging tool then better WARN_ON instead no?

[PATCH v2 16/18] mac80211 hwsim: verify vif pointers

[Johannes Berg]

mac80211-hwsim is a debugging tool for mac80211, and as such
it can very well verify that mac80211 isn't passing junk to
drivers, especially the vif pointer is prone to this because
for vlan interfaces the AP interface pointer needs to be passed.
This makes mac80211-hwsim add a magic cookie to the private vif
area and verify it whenever an operation is called that gets a
vif pointer.

this makes it very that it knows about all station structs.

[PATCH 22/18] mac80211: move txrate_idx into RC algorithms

[Johannes Berg]

The sta_info->txrate_idx member isn't used by all RC algorithms
in the way it was intended to be used, move it into those that
require it (only PID) and keep track in the core code of which
rate was last used for reporting to userspace and the mesh MLME.

[PATCH 23/18] mac80211: share sta_info->ht_info

[Johannes Berg]

Rate control algorithms may need access to a station's
HT capabilities, so share the ht_info struct in the
public station API.

[PATCH 24/18] iwlwifi: don't access mac80211's AMPDU state machine

[Johannes Berg]

There really is no need, at worst ieee80211_start_tx_ba_session
will log a message when debugging is enabled, and poking such
internals of mac80211 definitely doesn't belong into an RC
algorithm.

This would be very useful for ath9k. Making use of the
private area for each STA can enable removal of the node list
that is maintained currently.

I had actually tried
(http://johannes.sipsolutions.net/patches/kernel/ath9k-sta-node.patch)
but you're using refcounting for the nodes while mac80211 RCU-protects
them, so I didn't get very far. It needs a bit more effort to make sure
you don't have node pointers stick around in some tx descriptor after
mac80211 decides to remove a node (which may very well happen while
frames are queued)

Good thing I read RCU docs yesterday.

We should be able to remove ref counts and simply use RCU and
sychronize_rcu() before deletion.

We can call_rcu() here no, and let the driver deal with what it needs to
prior to deletion?

Well you don't get to control deletion then, that's another thing.

The driver already gets notified via sta_notify() that the sta is about
to be deleted, it must make sure that no matter what sort of references
it kept, the sta will not be accessed after that sta_notify call.

Does it matter? Our driver won't care as long as the entry still exists.
Just as with stale routing tables, does it matter if we keep thinking we
have a node for a few moments later?

Well, mostly that ath9k right now assumes it controls the lifetime, and
it won't do that afterwards, so since I didn't want to read all of the
code I failed to change it that way because I didn't know where node
pointers are kept. It's not a huge issue really, but the lifetime
management change is somewhat involved, I think.

Well take the larger bit of code:

	struct something *an = NULL;

...

	rcu_read_lock();
	sta = ieee80211_find_sta(hw, hdr->addr2);
	if (sta)
		an = (void *) sta->drv_priv;
 
 	if (an) {
 		ath_rx_input(sc, an,
 			     hw->conf.ht_conf.ht_supported,
 			     skb, status, &st);
 	}
	rcu_read_unlock();

	/* the "!an" here is fine even outside RCU lock */
 	if (!an || (st != ATH_RX_CONSUMED))
 		__ieee80211_rx(hw, skb, &rx_status);


So at this point it's only checking whether above it had a pointer, it's
not accessing it. Think of the "an" variable, after rcu_read_unlock(),
as a bool indicating whether or not the code that just happened had
access to the node or not.

That said, here it's probably smarter to just initialise "st" to
something other than _RX_CONSUMED and remove that !an condition
entirely.
