      mac80211: clean up/fix aggregation code · 098a6070
      由 Johannes Berg 提交于 
      The aggregation code has a number of quirks, like
inventing an unneeded WLAN_BACK_TIMER value and
leaking memory under certain circumstances during
station destruction. Fix these issues by using
the regular aggregation session teardown code and
blocking new aggregation sessions, all before the
station is really destructed.

As a side effect, this gets rid of the long code
block to destroy aggregation safely.

Additionally, rename tid_state_rx which can only
have the values IDLE and OPERATIONAL to
tid_active_rx to make it easier to understand
that there is no bitwise stuff going on on the
RX side -- the TX side remains because it needs
to keep track of the driver and peer states.

      mac80211: split up and insert custom IEs correctly · 8e664fb3
      由 Johannes Berg 提交于 
      Currently, we insert all user-specified IEs before the HT
IE for association, and after the HT IE for probe requests.
For association, that's correct only if the user-specified
IEs are RSN only, incorrect in all other cases including
WPA. Change this to split apart the user-specified IEs in
two places for association: before the HT IE (e.g. RSN),
after the HT IE (generally empty right now I think?) and
after WMM (all other vendor-specific IEs). For probes,
split the IEs in different places to be correct according
to the spec.

      mac80211: fix peer HT capabilities · 9a418af5
      由 Johannes Berg 提交于 
      I noticed yesterday, because Jeff had noticed
a speed regression, cf. bug
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2138
that the SM PS settings for peers were wrong.
Instead of overwriting the SM PS settings with
the local bits, we need to keep the remote bits.

The bug was part of the original HT code from
over two years ago, but unfortunately nobody
noticed that it makes no sense -- we shouldn't
be overwriting the peer's setting with our own
but rather keep it intact when masking the peer
capabilities with our own.

While fixing that, I noticed that the masking of
capabilities is completely useless for most of
the bits, so also fix those other bits.

Finally, I also noticed that PSMP_SUPPORT no
longer exists in the final 802.11n version, so
also remove that.

      mac80211: Robust Action frame categories for MFP · 528769cf
      由 Jouni Malinen 提交于 
      IEEE 802.11w/D9.0 introduces a mechanism for Action field Category
values to be used to select which Action frames are Robust. Public and
Vendor-specific categories are marked as not Robust in IEEE 802.11w;
HT will be marked not Robust in IEEE 802.11n. A new Vendor-specific
Protected category is allocated for Robust vendor-specific Action
frames. Another new category, Protected Dual of Action, is introduced
for protecting some existing Public Action frames (e.g., IEEE 802.11y
protected enablement).

      nl80211: Add MLME primitives to support external SME · 636a5d36
      由 Jouni Malinen 提交于 
      This patch adds new nl80211 commands to allow user space to request
authentication and association (and also deauthentication and
disassociation). The commands are structured to allow separate
authentication and association steps, i.e., the interface between
kernel and user space is similar to the MLME SAP interface in IEEE
802.11 standard and an user space application takes the role of the
SME.

The patch introduces MLME-AUTHENTICATE.request,
MLME-{,RE}ASSOCIATE.request, MLME-DEAUTHENTICATE.request, and
MLME-DISASSOCIATE.request primitives. The authentication and
association commands request the actual operations in two steps
(assuming the driver supports this; if not, separate authentication
step is skipped; this could end up being a separate "connect"
command).

The initial implementation for mac80211 uses the current
net/mac80211/mlme.c for actual sending and processing of management
frames and the new nl80211 commands will just stop the current state
machine from moving automatically from authentication to association.
Future cleanup may move more of the MLME operations into cfg80211.

The goal of this design is to provide more control of authentication and
association process to user space without having to move the full MLME
implementation. This should be enough to allow IEEE 802.11r FT protocol
and 802.11s SAE authentication to be implemented. Obviously, this will
also bring the extra benefit of not having to use WEXT for association
requests with mac80211. An example implementation of a user space SME
using the new nl80211 commands is available for wpa_supplicant.

This patch is enough to get IEEE 802.11r FT protocol working with
over-the-air mechanism (over-the-DS will need additional MLME
primitives for handling the FT Action frames).

      cfg80211/mac80211: Add 802.11d support · 3f2355cb
      由 Luis R. Rodriguez 提交于 
      This adds country IE parsing to mac80211 and enables its usage
within the new regulatory infrastructure in cfg80211. We parse
the country IEs only on management beacons for the BSSID you are
associated to and disregard the IEs when the country and environment
(indoor, outdoor, any) matches the already processed country IE.

To avoid following misinformed or outdated APs we build and use
a regulatory domain out of the intersection between what the AP
provides us on the country IE and what CRDA is aware is allowed
on the same country.

A secondary device is allowed to follow only the same country IE
as it make no sense for two devices on a system to be in two
different countries.

In the case the AP is using country IEs for an incorrect country
the user may help compliance further by setting the regulatory
domain before or after the IE is parsed and in that case another
intersection will be performed.

CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA
present.

      mac80211_hwsim: Add support for client PS mode · fc6971d4
      由 Jouni Malinen 提交于 
      This introduces a debugfs file (ieee80211/phy#/hwsim/ps) that can be
used to force a simulated radio into power save mode. Following values
can be written into this file to change PS mode:
0 = power save disabled (constantly awake)
1 = power save enabled (drop all frames; do not send PS-Poll)
2 = power save enabled (send PS-Poll frames automatically to receive
    buffered unicast frames); not yet fully implemented
3 = manual PS-Poll trigger (send a single PS-Poll frame)

Two different behavior for power save mode processing can be tested:
- move between modes 1 and 0 (i.e., receive all buffered frames at a
  time)
- move to mode 1 and use manual PS-Poll frames (write 3 to the 'ps'
  debugfs file) to fetch power save buffered frames one at a time

Mode 2 (automatic PS-Poll) does not yet parse Beacon frames, but
eventually, it should take a look at TIM IE and send PS-Poll if a
traffic bit is set for our AID.
