  • 3f2355cb9   cfg80211/mac80211: Add 802.11d support ... Browse Code »

    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    To avoid following misinformed or outdated APs we build and use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.

  • fc6971d49   mac80211_hwsim: Add support for client PS mode ... Browse Code »

    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.

  • 79617deee   mac80211: mesh portal functionality support ... Browse Code »

    Currently the mesh code doesn't support bridging mesh point interfaces
    with wired ethernet or AP to construct an MPP or MAP. This patch adds
    code to support the "6 address frame format packet" functionality to
    mesh point interfaces. Now the mesh network can be used as backhaul
    for end to end communication.

  • fd7c8a40b   mac80211: add helpers for frame control testing ... Browse Code »

    A few general categories:

    1) ieee80211_has_* tests if particular fctl bits are set, the helpers are de
    in the same order as the fctl defines:

    A combined _has_a4 was also added to test when both FROMDS and TODS are set.

    2) ieee80211_is_* is meant to test whether the frame control is of a certain
    ftype - data, mgmt, ctl, and two special helpers _is_data_qos, _is_data_pres
    which also test a subset of the stype space.

    When testing for a particular stype applicable only to one ftype, functions
    like ieee80211_is_ack have been added. Note that the ftype is also being
    checked in these helpers. They have been added for all mgmt and ctl stypes
    in the same order as the STYPE defines.

    3) ieee80211_get_* is meant to take a struct ieee80211_hdr * and returns a
    pointer to somewhere in the struct, see get_SA, get_DA, get_qos_ctl.

    The intel wireless drivers had helpers that used this namespace, convert the
    all to use the new helpers and remove the byteshifting as they were defined
    in cpu-order rather than little-endian.

  • 9306102ea   mac80211: allow disable FAT in specific configurations ... Browse Code »

    This patch allows to disable FAT channel in specific configurations.

    For example the configuration (8, +1), (primary channel 8, extension
    channel 12) isn't permitted in U.S., but (8, -1), (primary channel 8,
    extension channel 4) is. When FAT channel configuration is not
    permitted, FAT channel should be reported as not supported in the
    capabilities of the HT IE in association request. And sssociation is
    performed on 20Mhz channel.

    This patch follows the 11n spec in separation between Tx and Rx MCS
    capabilities. Up until now, when configuring the HT possible set of Tx
    MCS only Rx MCS were considered, assuming they are the same as the Tx MCS.
    This patch fixed this by looking at low level driver Tx capabilities.

  • 5628221ca   [PATCH] mac80211: ERP IE handling improvements ... Browse Code »

    The "protection needed" flag is currently parsed out of the ERP IE in
    beacons. This patch allows the ERP IE to be available at assocation time
    and causes the appropriate actions to be performed earlier.

    It is slightly complicated by the fact that most APs don't include the
    ERP IE in association responses. To work around this, we store ERP
    values in the ieee80211_sta_bss structure.

    Also added some WLAN_ERP defines for use by upcoming patches.
