    Check for cfg80211_ops structures that are only passed as the first
    argument to the function wiphy_new. As this argument is constant, so
    cfg80211_ops structures having this property can also be declared
    constant.
    Done using coccinelle:

  • 1d76250bd   nl80211: support beacon report scanning ... Browse Code »

    Beacon report radio measurement requires reporting observed BSSs
    on the channels specified in the beacon request. If the measurement
    mode is set to passive or active, it requires actually performing a
    scan (passive or active, accordingly), and reporting the time that
    the scan was started and the time each beacon/probe was received
    (both in terms of TSF of the BSS of the requesting AP). If the
    request mode is table, this information is optional.
    In addition, the radio measurement request specifies the channel
    dwell time for the measurement.

    In order to use scan for beacon report when the mode is active or
    passive, add a parameter to scan request that specifies the
    channel dwell time, and add scan start time and beacon received time
    to scan results information.

    Supporting beacon report is required for Multi Band Operation (MBO).

    hif_drv->usr_scan_req.net.net_info[i] contains found_net_info structs
    which have the following element:
    u8 bssid[6];

    pstrNetworkInfo, of type network_info, also contains an u8 array named
    bssid.

    request->ssids is an array of cfg80211_ssid structs. Making ssid:
    u8 ssid[IEEE80211_MAX_SSID_LEN];

    In these 3 cases the arrays are being checked against NULL, which can't
    happen. Removing the checks since they will always be true.

    Found with smatch:
    drivers/staging/wilc1000/host_interface.c:1234 Handle_RcvdNtwrkInfo() warn: this array is probably non-NULL. 'hif_drv->usr_scan_req.net_info[i].bssid'

    Pull staging and IIO driver updates from Greg KH:
    "Here's the big staging and iio driver update for 4.7-rc1.

    I think we almost broke even with this release, only adding a few more
    lines than we removed, which isn't bad overall given that there's a
    bunch of new iio drivers added.

    The Lustre developers seem to have woken up from their sleep and have
    been doing a great job in cleaning up the code and pruning unused or
    old cruft, the filesystem is almost readable :)

    Other than that, just a lot of basic coding style cleanups in the
    churn. All have been in linux-next for a while with no reported
    issues"

    "mac" is an array allocated in stack without being initialized,
    and will be sent out via "nla_put". The dump_station() is supposed
    to initialize the mac address; otherwise, sensitive data in kernel
    stack will be leaked. To fix this, copy the mac address to it.

    This patch is adds a check routine when performed del_key().
    We was find this situation while test the 'rmmod sdio'.
    That is received inform a .del_key cmd from cfg80211.
    If is not exist wep keys, must be ignore a wilc_remove_wep_key() function.
    Thus, adds a check routine that key length of wep.

    We was find this situation while test the 'rmmod sdio'.
    SDIO remove function are include both remove mac_close and unregister net_device.
    That is received one more a disconnect cmd from cfg80211.

  • 57fbcce37   cfg80211: remove enum ieee80211_band ... Browse Code »

    This enum is already perfectly aliased to enum nl80211_band, and
    the only reason for it is that we get IEEE80211_NUM_BANDS out of
    it. There's no really good reason to not declare the number of
    bands in nl80211 though, so do that and remove the cfg80211 one.

    Variables pcgroup_encrypt_val,pccipher_group,pcwpa_version,

    connect(), however they are not being used anywhere.
    Hence, the unused variables have been removed.

    This was done using Coccinelle.
