We shouldn't be looking at the ssid_len for non-IBSS,
and for IBSS we should also return an error on trying
to leave an IBSS while not in or joining an IBSS.
This fixes an issue where we wouldn't disconnect() on
an interface being taken down since there's no SSID
configured this way.

Otherwise it becomes very hard to reset the structs
correctly since wext can be configured while the
interface is down.

After the mac80211 mlme cleanup, we can require that
the MLME functions in cfg80211 can sleep. This will
simplify future work in cfg80211 a lot.

The original code in mac80211 could send a deauth
frame under certain circumstances even if nothing
had ever requested an authentication. This has been
fixed with the rework there, so cfg80211 can now
warn again about spurious events to catch possible
future drivers or mac80211 regressions.

Currently we call that cfg80211_put_dev(), but that is
misleading. With the new convention of using 'rdev' for
registered_device variables, also call that function
cfg80211_unlock_rdev().

sparse warns about a number of things, and one of them
(use_mfp shadowed variable) actually is a bug, fix all
of them.

Over time, a lot of locking issues have crept into
the smarts of cfg80211, so e.g. scan completion can
race against a new scan, IBSS join can race against
leaving an IBSS, etc.
Introduce a new per-interface lock that protects
most of the per-interface data that we need to keep
track of, and sprinkle assertions about that lock
everywhere. Some things now need to be offloaded to
work structs so that we don't require being able to
sleep in functions the drivers call. The exception
to that are the MLME callbacks (rx_auth etc.) that
currently only mac80211 calls because it was easier
to do that there instead of in cfg80211, and future
drivers implementing those calls will, if they ever
exist, probably need to use a similar scheme like
mac80211 anyway...
In order to be able to handle _deauth and _disassoc
properly, introduce a cookie passed to it that will
determine locking requirements.

To: John Linville; +Cc: linux-wireless
We've named the registered devices 'drv' sometimes,
thinking of "driver", which is not what it is, it's
the internal representation of a wiphy, i.e. a
device. Let's clean up the naming once and and use
'rdev' aka 'registered device' everywhere.

8 siblings, 0 replies; 10+ messages in thread
From: Johannes Berg @ 2009-07-07 1:56 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless
In order to force drivers to advertise their interface
types, don't just disallow creating new interfaces with
unadvertised types but also disallow setting them UP.
Additionally, add some validation on the operations the
drivers support.
