2009-03-05ath5k: Set TSF fixAlina Friedrichsen1-2/+1
The old code doesn't work correctly e.g. on newer chipsets like AR5418+AR2122 and AR5416+AR2133. Signed-off-by: Alina Friedrichsen <x-alina@gmx.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-01-29ath5k: Read and write the TSF via debugfsAlina Friedrichsen1-0/+17
This patch updates the ath5k specific entry in the debugfs to read and reset the TSF value, to allowing write it, too. This makes debugging the IBSS handling of wifi drivers _much_ easier. Signed-off-by: Alina Friedrichsen <x-alina@gmx.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-01-29mac80211: 802.11w - Use BIP (AES-128-CMAC)Jouni Malinen1-0/+3
Add mechanism for managing BIP keys (IGTK) and integrate BIP into the TX/RX paths. Signed-off-by: Jouni Malinen <j@w1.fi> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-01-29mac80211: clean up set_key callbackJohannes Berg1-1/+1
The set_key callback now seems rather odd, passing a MAC address instead of a station struct, and a local address instead of a vif struct. Change that.

2009-01-12ath5k: Correct usage of AR5K_CFG_ADHOCSteve Brown1-2/+2
This corrects usage of AR5K_CFG_ADHOC introduced in "ath5k: Update PCU code". Also, the name of the indicator is changed to AR5K_CFG_IBSS to more accurately reflect its function. This change restores beaconing in AP and mesh modes. Signed-off-by: Steve Brown <sbrown@cortland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-12-05ath5k: enable combined michael mic in key cacheBob Copeland1-14/+14
For mac revisions >= "Griffin," the hardware allows the mic tx and rx authenticator keys to share the same cache line, whereas earlier hardware can only store the rx. Enable the combined mic on hardware that supports it.

2008-12-05ath5k: clean up ath5k_hw_set_keyBob Copeland1-24/+34
Status: O With the addition of TKIP (and soon CCMP), key->alg is a more useful guide to key type than the key length. This patch cleans up key type assignment in ath5k_hw_set_key by extracting it into its own function. It also replaces the separate memcpy() calls for extracting key material into the hardware format with a loop that works regardless of key size. Finally, the patch removes support for WEP-128 since it is a non-standard key length that mac80211 also doesn't use.

2008-12-05ath5k: preserve higher order bits when setting mac addressBob Copeland1-5/+4
In some cases we would like to set the mac address without changing the operating mode. However, Atheros cards store PCU data in the high 16 bits of the mac address register. Change ath5k_hw_set_lladdr() to not clobber the PCU settings. Changes-licensed-under: ISC Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-11-10ath5k: update keycache to support TKIP handlingBob Copeland1-5/+59
Newer parts have slots at entry+64 for michael mic and can do WPA-TKIP in hardware. The open-sourced Atheros HAL has code for accessing this portion so now we know how where to put the key material.

2008-11-10ath5k: Update PCU codeNick Kossifidis1-20/+91
* In set_opmode don't handle antenna settings and preserve other STA_ID1 settings (shouldn't matter because we call it during reset but it makes things cleaner) Also set properly AP/ADHOC indicator flag on CFG while setting AP/ADHOC modes and always enable key search mode. * Properly set BSSID Mask during reset (cache it and reuse it durring set_associd) * Update beacon_init to flush pending BMISS interrupts and handle setting of adhoc beacon ATIM policy flag for ad-hoc mode. Also set TSF to 0 to start TSF increment on AP mode. We need to handle sleep timers for AR5212 there + add support for PCF. * Properly clean MIC key from keytable when TKIP is used (Bob is working on set_key function etc so i leave it for now). Tested on AR5212 (Hainan) and AR5413 and works fine v2 Set PISR on AR5211+ and ISR on AR5210, got to sleep more ;-) Changes-Licensed-under: ISC Signed-Off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2008-09-30ath5k: write beacon control register twice when resetting tsfBob Copeland1-1/+13
According to the newly-released Atheros HAL code, asserting the TSF reset bit will toggle a hardware internal state, resulting in a spurious reset on the next chip reset. Whenever we force a TSF bit, write the bit twice to clear the internal signal. Signed-off-by: Bob Copeland <me@bobcopeland.com> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2008-09-15mac80211: use nl80211 interface typesJohannes Berg1-6/+6
There's really no reason for mac80211 to be using its own interface type defines. Use the nl80211 types and simplify the configuration code a bit: there's no need to translate them any more now.

2008-09-05ath5k: HW code cleanupNick Kossifidis1-0/+1002
* No code changes... * Split hw.c to multiple files for better maintenance and add some documentation on each file code is going to grow soon (eeprom.c for example is going to get much stuff currently developed on ath_info) so it's better this way. * Rename following functions to maintain naming scheme: ah_setup_xtx_desc -> ah_setup_mrr_tx_desc (Because xtx doesn't say much, it's actually a multi-rate-retry tx descriptor) ath5k_hw_put_tx/rx_buf - > ath5k_hw_set_tx/rxdp ath5k_hw_get_tx/rx_buf -> ath5k_hw_get_tx/rxdp (We don't put any "buf" we set descriptor pointers on hw) ath5k_hw_tx_start -> ath5k_hw_start_tx_dma ath5k_hw_start_rx -> ath5k_hw_start_rx_dma ath5k_hw_stop_pcu_recv -> ath5k_hw_stop_rx_pcu (It's easier this way to identify them, we also have ath5k_hw_start_rx_pcu which completes the set) ath5k_hw_set_intr -> ath5k_hw_set_imr (As in get_isr we set imr here, not "intr") * Move ath5k_hw_setup_rx_desc on ah->ah_setup_rx_desc so we can include support for different rx descriptors in the future * Further cleanups so that checkpatch doesn't complain (only some > 80 col warnings for eeprom.h and reg.h as usual due to comments) Tested on 5211 and 5213 cards and works ok.
