Part of reorganising wireless drivers directory and Kconfig. Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-07-21mwifiex: fix leak of gen_ie storage on exit from mwifiex_del_mgmt_iesJohn Linville
Storage pointed to by gen_ie is allocated with kmalloc, but was never freed. Coverity CID #1271251 Signed-off-by: John W. Linville <linville@tuxdriver.com> Acked-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-07-21mwifiex: do not short circuit exit from mwifiex_set_mgmt_iesJohn Linville
Without this change, the code simply exits after calling mwifiex_uap_set_head_tail_ies, leving the call to mwifiex_set_mgmt_beacon_data_ies as dead code. Coverity CID #1271292 Signed-off-by: John W.

2015-06-08mwifiex: support downloading IEs from tailAvinash Patil
Earlier only RSN, WPA and channel switch IEs from tail buffer would be downloaded to FW. This patch adds support for downloading more IEs from tail buffer. Signed-off-by: Avinash Patil <patila@marvell.com> Signed-off-by: Cathy Luo <cluo@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-01-29mwifiex: channel switch support for mwifiexAvinash Patil
This patch adds cfg80211 channel_switch support for mwifiex. Upon receiving channel switch request, driver would parse channel switch announcement IE from beacon_data. If TX is blocked, netdev queues are stopped. IEs from csa_beacon are then parsed and set to FW.

2015-01-29mwifiex: separate function for parsing head and tail IEsAvinash Patil
Head & Tail IEs are supposed to be added to beacon and probe response. This patch adds separate function for parsing head and tail IEs from cfg80211_beacon_data and sets them to FW.

2014-02-28mwifiex: remove global variable cmd_wait_q_requiredBing Zhao
There is a race condition while queuing synchronous command and asynchronous command requested from different threads, because the wait_q_enabled flag is set based on a global variable cmd_wait_q_required. The issue is fixed by removing this global variable and using a unified function with an argument 'sync' passed into the function.

2013-11-11mwifiex: fix invalid memory access in mwifiex_update_autoindex_ies()Amitkumar Karwar
While parsing TLVs, return failure if number of remaining bytes are less than current tlv length. This avoids invalid memory access. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-07-24mwifiex: remove duplicate structure host_cmd_tlvAmitkumar Karwar
We already have 'struct mwifiex_ie_types_header' with same definition. Hence host_cmd_tlv is removed in this patch. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2012-09-25mwifiex: potential corruption in mwifiex_update_uap_custom_ie()Dan Carpenter
ap_custom_ie is a struct mwifiex_ie_list which is quite different and also larger than struct mwifiex_ie. It's a difference between 4196 bytes and 262.

2012-07-09mwifiex: parse WPS IEs from beacon_dataAvinash Patil
Parse WPS IEs from start_ap as well as change_beacon handlers and set them to FW. Beacon IEs, Probe Response IEs and Assoc Response IEs are parsed from beacon_data and set to FW with related masks.

2012-07-09mwifiex: overwrite earlier IE buffers for new set IE requestAvinash Patil
All IE buffers are freshly supplied. In such case, there is no need to preserve earlier buffers with same management mask and index. Signed-off-by: Avinash Patil <patila@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-07-09mwifiex: separate IE parsing for Head/Tail IEs and beacon_ies etcAvinash Patil
While Head/Tail IEs may contain RSN/WPA IEs which needs to be set for all mgmt subtypes, beacon_ies, probe_resp_ies, assoc_resp_ies are for specific mgmt subtypes. Move them to separate function.

Pass cfg80211_beacon_data pointer instead of cfg80211_ap_settings. While setting management IEs we only need cfg80211_beacon_data of cfg80211_ap_settings which has Tail IE, Head IE and other IE elements.
