From 7bcfaf2f431c09c51fe776fc06638b25d3b421c5 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 27 Oct 2009 12:59:03 +0100 Subject: cfg80211/mac80211: use debugfs_remove_recursive We can save a lot of code and pointers in the structs by using debugfs_remove_recursive(). First, change cfg80211 to use debugfs_remove_recursive() so that drivers do not need to clean up any files they added to the per-wiphy debugfs (if and only if they are ok to be accessed until after wiphy_unregister!). Then also make mac80211 use debugfs_remove_recursive() where necessary -- it need not remove per-wiphy files as cfg80211 now removes those, but netdev etc. files still need to be handled but can now be removed without needing struct dentry pointers to all of them.

Vice versa, if the hardware is operating on 5 GHz the 2.4 GHz probe requests will not include CCK rates even though they should. Fix this by splitting up cfg80211 scan requests by band -- recalculating the IEs every time -- and requesting only per-band scans from the driver. Apparently this bug hasn't been a problem yet, but it is imaginable that some older access points get confused if confronted with such behaviour. Signed-off-by: Johannes Berg Signed-off-by: John W.

For this to work, both the client and the AP need to transmit 4-address frames, containing both source and destination MAC addresses. With this patch, you can configure a client to communicate using only 4-address frames for data traffic. On the AP side you can enable 4-address frames for individual clients by isolating them in separate AP VLANs which are configured in 4-address mode. Such an AP VLAN will be limited to one client only, and this client will be used as the destination for all traffic on its interface, regardless of the destination MAC address in the packet headers. The advantage of this mode compared to regular WDS mode is that it's easier to configure and does not require a static list of peer MAC addresses on any side.

Also, keep track of 4addr in cfg80211 (wireless_dev) and not in mac80211 any more. mac80211 can also be improved for the VLAN case by not looking at the 4addr flag but maintaining the station pointer for it correctly. However, keep track of use_4addr for station mode in mac80211 to avoid all the derefs. Signed-off-by: Johannes Berg Signed-off-by: John W.

The previous patch moved the code there, and this patch now hooks it up in that place by introducing a list of skbs that are then processed by the remaining handlers. The list may be empty if the function is buffering the skb to release it later. The only change needed to the RX data is that the crypto handler needs to clear the key that may be set from a previous loop iteration, and that not everything can be in the rx flags now.
