cfg80211: rework key operation

2009-07-24T19:05:09+00:00

This reworks the key operation in cfg80211, and now only
allows, from userspace, configuring keys (via nl80211)
after the connection has been established (in managed
mode), the IBSS been joined (in IBSS mode), at any time
(in AP[_VLAN] modes) or never for all the other modes.

In order to do shared key authentication correctly, it
is now possible to give a WEP key to the AUTH command.
To configure static WEP keys, these are given to the
CONNECT or IBSS_JOIN command directly, for a userspace
SME it is assumed it will configure it properly after
the connection has been established.

Since mac80211 used to check the default key in IBSS
mode to see whether or not the network is protected,
it needs an update in that area, as well as an update
to make use of the WEP key passed to auth() for shared
key authentication.

mac80211: refactor the WEP code to be directly usable

2009-07-10T19:02:31+00:00

The new key work for cfg80211 will only give us the WEP
key for shared auth to do that authentication, and not
via the regular key settings, so we need to be able to
encrypt a single frame in software, and that without a
key struct. Thus, refactor the WEP code to not require
a key structure but use the key, len and idx directly.

mac80211: rewrite fragmentation

2009-03-28T00:13:21+00:00

Fragmentation currently uses an allocated array to store the
fragment skbs, and then keeps track of which have been sent
and which are still pending etc. This is rather complicated;
make it simpler by just chaining the fragments into skb->next
and removing from that list when sent. Also simplifies all
code that needs to touch fragments, since it now only needs
to walk the skb->next list.

This is a prerequisite for fixing the stored packet code,
which I need to do for proper aggregation packet storing.

mac80211: rework debug settings and make debugging safer

2008-07-02T19:48:33+00:00

This patch reworks the mac80211 debug settings making them more focused
and adding help text for those that didn't have one. It also removes a
number of printks that can be triggered remotely and add no value, e.g.
"too short deauthentication frame received - ignoring".

If somebody really needs to debug that they should just add a monitor
interface and look at the frames in wireshark.
