mac80211: rename files

2008-04-08T20:44:45+00:00

This patch renames all mac80211 files (except ieee80211_i.h) to get rid
of the useless ieee80211_ prefix.

mac80211: make debugfs files root-only

2008-04-08T20:44:43+00:00

Unfortunately, debugfs can be made to access invalid memory by
open()ing a file and then waiting until the corresponding debugfs
file has been removed (and, probably, the underlying object.)

That could be exploited by any user if the user is able to open
debugfs files and can cause networking devices, STA entries or
similar to disappear which is quite easy to do.

Hence, all debugfs files should be root-only.

net/mac80211/debugfs_netdev.c: use of bool triggers a gcc bug

2008-04-01T21:13:17+00:00

This bool causes my gcc-4.1.0 alpha cross compiler to go into an infinite
loop.  Switching it to u8 works around that.

mac80211: mesh statistics and config through debugfs

2008-03-06T20:30:42+00:00

This patch contains the debugfs code for mesh statistics and configuration
parameters. Please note that generic support for r/w debugfs attributes has been
added.

mac80211: remove port control enable switch, clean up sta flags

2008-02-29T20:19:33+00:00

This patch removes the 802.1X port acess control enable flag
since it is not required. Instead, set the authorized flag for
each station that we normally communicate with (WDS peers, IBSS
peers and APs we're associated to) and require hostapd to set
the authorized flag for all stations when port control is not
enabled.

Also, since I was working in that area, this documents station
flags and removes the unused "permanent" one.

mac80211: add unified BSS configuration

2008-01-28T23:09:43+00:00

This patch (based on Ron Rindjunsky's) creates a framework for
a unified way to pass BSS configuration to drivers that require
the information, e.g. for implementing power save mode.

This patch introduces new ieee80211_bss_conf structure that is
passed to the driver via the new bss_info_changed() callback
when the BSS configuration changes.

This new BSS configuration infrastructure adds the following
new features:
 * drivers are notified of their association AID
 * drivers are notified of association status

and replaces the erp_ie_changed() callback. The patch also does
the relevant driver updates for the latter change.

mac80211: add beacon configuration via cfg80211

2008-01-28T23:09:38+00:00

This patch implements the cfg80211 hooks for configuring beaconing
on an access point interface in mac80211. While doing so, it fixes
a number of races that could badly crash the machine when the
beacon is changed while being requested by the driver.

mac80211: move interface type to vif structure

2008-01-28T23:09:37+00:00

Drivers that support mixed AP/STA operation may well need to
know the type of a virtual interface when iterating over them.
The easiest way to support that is to move the interface type
variable into the vif structure.

mac80211: clean up eapol frame handling/port control

2008-01-28T22:59:45+00:00

This cleans up the eapol frame handling and some related code in the
receive and transmit paths. After this patch
 * EAPOL frames addressed to us or the EAPOL group address are
   always accepted regardless of whether they are encrypted or not
 * other frames from a station are dropped if PAE is enabled and
   the station is not authorized
 * unencrypted frames (except the EAPOL frames above) are dropped if
   drop_unencrypted is enabled
 * some superfluous code that eth_type_trans handles anyway is gone
 * port control is done for transmitted packets
