* net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modulesPaul Gortmaker2011-10-31
| | | | | | | | | These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

* nl80211: Add sta_flags to the station infoHelmut Schaa2011-10-14
| | | | | | | | | | Reuse the already existing struct nl80211_sta_flag_update to specify both, a flag mask and the flag set itself.

* mac80211: data path modification for TDLS peersArik Nemtsov2011-09-30
| | | | | | | | | | | | | | | | | | | Mark the STA entries of enabled TDLS peers with a new "peer authorized" flag. During link setup, allow special TDLS setup frames through the AP, but otherwise drop all packets destined to the peer. This is required by the TDLS (802.11z) specification in order to prevent reordering of MSDUs between the AP and direct paths. When setup completes and the peer is authorized, send data directly, bypassing the AP. In the Rx path, allow data to be received directly from TDLS peers.

* nl80211/mac80211: allow adding TDLS peers as stationsArik Nemtsov2011-09-30
| | | | | | | | | | | | | | | | When adding a TDLS peer STA, mark it with a new flag in both nl80211 and mac80211. Before adding a peer, make sure the wiphy supports TDLS and our operating mode is appropriate (managed). In addition, make sure all peers are removed on disassociation. A TDLS peer is first added just before link setup is initiated. In later setup stages we have more info about peer supported rates, capabilities, etc. This info is reported via nl80211_set_station().

* cfg80211/mac80211: apply station uAPSD parameters selectivelyJohannes Berg2011-09-30
| | | | | | | | | | | | Currently, when hostapd sets the station as authorized we also overwrite its uAPSD parameter. This obviously leads to buggy behaviour (later, with my patches that actually add uAPSD support). To fix this, only apply those parameters if they were actually set in nl80211, and to achieve that add a bitmap of things to apply.

| * cfg80211: Fix validation of AKM suitesJouni Malinen2011-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Incorrect variable was used in validating the akm_suites array from NL80211_ATTR_AKM_SUITES. In addition, there was no explicit validation of the array length (we only have room for NL80211_MAX_NR_AKM_SUITES). This can result in a buffer write overflow for stack variables with arbitrary data from user space. The nl80211 commands using the affected functionality require GENL_ADMIN_PERM, so this is only exposed to admin users.

* | nl80211/cfg80211: Add support to disable CCK rate for management frameRajkumar Manoharan2011-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new nl80211 attribute to specify whether to send the management frames in CCK rate or not. As of now the wpa_supplicant is disabling CCK rate at P2P init itself. So this patch helps to send P2P probe request/probe response/action frames being sent at non CCK rate in 2GHz without disabling 11b rates. This attribute is used with NL80211_CMD_TRIGGER_SCAN and NL80211_CMD_FRAME commands to disable CCK rate for management frame transmission.

* | cfg80211: Validate cipher suite against supported ciphersJouni Malinen2011-09-27
| | | | | | | | | | | | | | | | | | | | Instead of using a hardcoded list of cipher suites in nl80211.c, use a shared function in util.c to verify that the driver advertises support for the specified cipher.

* | cfg80211: Remove strict validation of AKM suitesJouni Malinen2011-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NL80211_ATTR_AKM_SUITES can be used to configure new AKMs, like FT or the SHA-256 -based AKMs or FT from 802.11r/802.11w. In addition, vendor specific AKMs could be used. The current validation code for the connect command prevents cfg80211-based drivers from using these mechanisms even if the driver would not actually use this AKM value (i.e., it uses WPA/RSN IE from user space). mac80211-based drivers allow any AKM to be used since this value is not used there. Remove the unnecessary validation step in cfg80211 to allow drivers to decide what AKMs are supported. In theory, we could handle this by advertising supported AKMs, but that would not be very effective unless we enforce all drivers (including mac80211) to advertise the set of supported AKMs. This would require additional changes in many places whenever a new AKM is introduced even though no actually functionality changes may be required in most drivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the association, the regulatory is updated by country IE that reaps the previously found beacons. The impact is that after a STA disconnects *or* when for any reason a regulatory domain change happens the beacon hint flag is not cleared therefore preventing future beacon hints to be learned. This is important as a regulatory domain change or a restore of regulatory settings would set back the passive scan and no-ibss flags on the channel. This is the right place to do this given that it covers any regulatory domain change. Cc: stable@kernel.org Reviewed-by: Luis R.

Since firmware based roaming is faster, inform wpa_supplicant to avoid roaming and let the firmware decide to roam if necessary. For fullmac drivers like ath6kl, it is just enough to provide the ESSID and the firmware will decide on the BSSID. Since it is not possible to do pre-auth during roaming for fullmac drivers, the wpa_supplicant needs to completely disconnect with the old AP and reconnect with the new AP.

* | cfg80211: fix a crash in nl80211_send_stationFelix Fietkau2011-08-11
| | | | | | | | | | | | | | | | | | | | mac80211 leaves sinfo->assoc_req_ies uninitialized, causing a random pointer memory access in nl80211_send_station. Instead of checking if the pointer is null, use sinfo->filled, like the rest of the fields. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | cfg80211/nl80211: Send AssocReq IEs to user space in AP modeJouni Malinen2011-08-10
| | | | | | | | | | | | | | | | | | | | | | When user space SME/MLME (e.g., hostapd) is not used in AP mode, the IEs from the (Re)Association Request frame that was processed in firmware need to be made available for user space (e.g., RSN IE for hostapd). Allow this to be done with cfg80211_new_sta(). Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* | nl80211: Indicate driver-based offchannel TX on mgmt_tx_cancel_waitJouni Malinen2011-08-10
| | | | | | | | | | | | | | | | | | | | | | Drivers that support frame transmission with mgmt_tx() may not support driver-based offchannel TX. Use mgmt_tx_cancel_wait instead of mgmt_tx when figuring out whether to indicate support for this with NL80211_ATTR_OFFCHANNEL_TX_OK.

* | cfg80211: remove unused wext handler exportsJohannes Berg2011-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of code is dedicated to giving drivers the ability to use cfg80211's wext handlers without completely converting. However, only orinoco is currently using this, and it is only partially using it. We reduce the size of both the source and binary by removing those that nobody needs. If a driver shows up that needs it during conversion, we can add back those that are needed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

* | cfg80211: split wext compatibility to separate headerJohannes Berg2011-08-08
|/ | | | | | | | | | | A lot of drivers erroneously use wext constants and don't notice since cfg80211.h includes them. Make this more split up so drivers needing wext compatibility from cfg80211 need to explicitly include that from cfg80211-wext.h.

* cfg80211: really ignore the regulatory requestSven Neumann2011-07-26
| | | | | | | | | | | | | | | | | | | | | | | At the beginning of wiphy_update_regulatory() a check is performed whether the request is to be ignored. Then the request is sent to the driver nevertheless. This happens even if last_request points to NULL, leading to a crash in the driver: [<bf01d864>] (lbs_set_11d_domain_info+0x28/0x1e4 [libertas]) from [<c03b714c>] (wiphy_update_regulatory+0x4d0/0x4f4) [<c03b714c>] (wiphy_update_regulatory+0x4d0/0x4f4) from [<c03b4008>] (wiphy_register+0x354/0x420) [<c03b4008>] (wiphy_register+0x354/0x420) from [<bf01b17c>] (lbs_cfg_register+0x80/0x164 [libertas]) [<bf01b17c>] (lbs_cfg_register+0x80/0x164 [libertas]) from [<bf020e64>] (lbs_start_card+0x20/0x88 [libertas]) [<bf020e64>] (lbs_start_card+0x20/0x88 [libertas]) from [<bf02cbd8>] (if_sdio_probe+0x898/0x9c0 [libertas_sdio]) Fix this by returning early.
