Subject: 802.11: clean up/fix HT support This patch cleans up a number of things: * the unusable definition of the HT capabilities/HT information information elements * variable names that are hard to understand * mac80211: move ieee80211_handle_ht to ht.c and remove the unused enable_ht parameter * mac80211: fix bug with MCS rate 32 in ieee80211_handle_ht * mac80211: fix bug with casting the result of ieee80211_bss_get_ie to an information element _contents_ rather than the whole element, add size checking (another out-of-bounds access bug fixed!) * mac80211: remove some unused return values in favour of BUG_ON checking * a few minor other things Signed-off-by: Johannes Berg --- drivers/net/wireless/ath9k/main.c | 57 +++++------ drivers/net/wireless/ath9k/rc.c | 10 - drivers/net/wireless/ath9k/rc.h | 1 drivers/net/wireless/ath9k/recv.c | 2 drivers/net/wireless/ath9k/xmit.c | 2 drivers/net/wireless/iwlwifi/iwl-agn-rs.c | 18 +-- drivers/net/wireless/iwlwifi/iwl-agn.c | 20 +-- drivers/net/wireless/iwlwifi/iwl-core.c | 71 +++++++------- drivers/net/wireless/iwlwifi/iwl-core.h | 2 drivers/net/wireless/iwlwifi/iwl-dev.h | 4 drivers/net/wireless/iwlwifi/iwl-scan.c | 12 +- drivers/net/wireless/iwlwifi/iwl-sta.c | 6 - drivers/net/wireless/mac80211_hwsim.c | 19 +-- include/linux/ieee80211.h | 133 ++++++++++++++++++-------- include/net/mac80211.h | 12 +- include/net/wireless.h | 15 +- net/mac80211/cfg.c | 7 - net/mac80211/ht.c | 151 +++++++++++++++++++++++++----- net/mac80211/ieee80211_i.h | 16 +-- net/mac80211/main.c | 94 ------------------ net/mac80211/mlme.c | 45 ++++---- net/mac80211/util.c | 4 net/mac80211/wext.c | 4 23 files changed, 386 insertions(+), 319 deletions(-) --- everything.orig/include/linux/ieee80211.h 2008-10-08 20:44:47.000000000 +0200 +++ everything/include/linux/ieee80211.h 2008-10-09 02:16:21.000000000 +0200 @@ -685,28 +685,88 @@ struct ieee80211_bar { #define IEEE80211_BAR_CTRL_ACK_POLICY_NORMAL 0x0000 #define IEEE80211_BAR_CTRL_CBMTID_COMPRESSED_BA 0x0004 + +#define IEEE80211_HT_MCS_MASK_LEN 10 + +/** + * struct ieee80211_mcs_info - MCS information + * @rx_mask: RX mask + * @rx_highest: highest supported RX rate + * @tx_params: TX parameters + */ +struct ieee80211_mcs_info { + u8 rx_mask[IEEE80211_HT_MCS_MASK_LEN];
