Since mwifiex only supports managed and IBSS modes, it doesn't need a set_channel call. The callback might be called, but it won't matter as nothing can use the channel. Signed-off-by:

1. Support for parsing security related parameters from cfg80211_ap_settings in start_ap cfg80211 handler 2. Conversion of these security information into FW understandle TLVs and setting into FW thru sys_config command 3. key management is done on host. This ensures that FW forwards EAPOL key packets to host instead of processing on its own. Signed-off-by:

Added logic to handle AP event that are generated by the firmware. As MLME/SME is implemented in the firmware, events such as station association and deauthentication, must be sent to userspace (hostapd) for creating and deleting station database. Signed-off-by:

Modify key related cfg80211 handlers to copy peer mac address for pairwise keys. If peer mac address is not present or group keys, it will be sent as broadcast mac address. This would be required since hostapd downloads per peer PTK. Signed-off-by:

Since wiphy structure is per adapter we would save adapter, instead of mwifiex private pointer, in wiphy_priv. Also move country_info from mwifiex_private to mwifiex_adapter as making it part of mwifiex_adapter looks logical. Signed-off-by:

1. wiphy structure is per device; hence moved it to mwifiex_adapter mwifiex_register_cfg80211 takes mwifiex_adapter as parameter. This function only registers wiphy with cfg80211. 2. Creation of interfaces is moved to cfg80211 add_virtual_interface handler. 3. Create 2 interfaces by default: station and AP Signed-off-by:

We get two timing related fields for each bss from firmware in scan results. 1) timestamp - Actual timestamp information in probe response/beacon 2) network_tsf - firmware's TSF value at the time the beacon or probe response was received. Both are needed while associating by firmware. The patch takes care of following things. 1) We should pass "timestamp" to cfg80211_inform_bss(), but currently "network_tsf" is being provided. This error is corrected here. 2) Rename "network_tsf" to "fw_tsf" 3) Make use of u64 variable instead of an array of u8/u32 to save parsed "timestamp" information. 4) Use timestamp provided to stack in scan results using cfg80211_inform_bss() while associating. (bss->tsf) 5) Allocate space to save fw_tsf in "priv" of cfg80211_bss and retrieve it while associating. Signed-off-by:

In recent commit "mwifiex: correct bitrates advertised..", we have removed 22Mbps and 72Mbps bitrates from supported bitrate array. It means number of bitrates has reduced from 14 to 12. Initialize ".n_bitrates" to array size instead of hardcoding it. Signed-off-by:

Currently if valid SSID list is provided in scan request, driver performs specific SSID scan otherwise wildcard scan is chosen. When wpa_supplicant provides valid SSID list followed by zero-length SSID for wildcard scan, only specific SSID scan is performed by driver. Actually driver is expected to do both type of scanning in this case. The patch fixes this issue. Also, use SSID list pointer provided by stack directly, instead of copying SSID's to local structure.

When authentication type is configured to NL80211_AUTHTYPE_AUTOMATIC, driver tries to connect using open mode. The association is failed if AP is configured in shared mode. This patch adds code to try association using shared mode as well if open mode association fails. Now since we returned exact error code in association response handler (instead of -1), corresponding changes are done in mwifiex_process_cmdresp(). Signed-off-by:

It should have been removed by commit "mwifiex: use cfg80211 dynamic scan..." (7c6fa2a8..) after adding code to avoid an extra scan during association because scan entries are valid for 15 seconds in cfg80211 stack. Signed-off-by:

Driver maintains different flags for WEP, WPA, WPA2 security modes. Appropriate flag is set using security information provided in connect request. mwifiex_is_network_compatible() routine uses them to check if driver's setting is compatible with AP. Association is aborted if the routine fails. For some corner cases, it is observed that association is failed even for valid security information based on association history. This patch fixes the problem by clearing previous security setting during each association. We should set WEP key provided in connect request as default tx key. This missing change is also added here. Signed-off-by:

Earlier we were using dtim period extracted from scan response buffer provided by FW in scan operation. But it is observed that sometimes the buffer doesn't contain dtim period tlv, and wrong value (0) was sent to user space. After association FW will start listening to beacon frames of connected AP and store dtim period. Therefore we can get it from FW in dump_station() instead of using wrong value obtained in scanning. Redundant code after adapting new approach for dtim period is also removed in this patch. Signed-off-by:

Currently mwifiex_private pointers are derived from wiphy structures. This will always work as long as there is only one net_device associated with one wiphy. In scenarios where there are multiple net_devices associated with single wiphy, one should use net_device to derive the priv. Signed-off-by:

Currently due to following issues in the code even if device is configured in B only, G only or BG mode using iw bitrates command, ibss is getting created in BGN mode. 1) mwifiex_channels_to_cfg80211_channel_type() routine gives channel type as NL80211_CHAN_HT20 for non-HT channel as well, because driver doesn't store HT information provided by stack for the channel. This issue is fixed by maintaining channel type information in 'adapter->channel_type'. 2) Band configuration is unnecessarily overwritten with BGN/AN while setting channel. This patch makes sure that "adapter->config_bands" correctly gets modified while setting channel. Signed-off-by:
