ath: Modify ath_key_delete() to not need full key entry

2020-12-17T06:51:17Z

tkip_keymap can be used internally to avoid the reference to key->cipher and with this, only the key index value itself is needed. This allows ath_key_delete() call to be postponed to be handled after the upper layer STA and key entry have already been removed. This is needed to make ath9k key cache management safer.

ath: Use safer key clearing with key cache entries

2020-12-17T06:51:07Z

It is possible for there to be pending frames in TXQs with a reference to the key cache entry that is being deleted. If such a key cache entry is cleared, those pending frame in TXQ might get transmitted without proper encryption. It is safer to leave the previously used key into the key cache in such cases. Instead, only clear the MAC address to prevent RX processing from using this key cache entry. This is needed in particularly in AP mode where the TXQs cannot be flushed on station disconnection. This change alone may not be able to address all cases where the key cache entry might get reused for other purposes immediately (the key cache entry should be released for reuse only once the TXQs do not have any remaining references to them), but this makes it less likely to get unprotected frames and the more complete changes may end up being significantly more complex.

ath9k: fix dynamic WEP related regression

2012-06-25T19:14:13Z

commit 7a532fe7131216a02c81a6c1b1f8632da1195a58 ath9k_hw: fix interpretation of the rx KeyMiss flag This commit used the rx key miss indication to detect packets that were passed from the hardware without being decrypted, however it seems that this bit is not only undefined in the static WEP case, but also for dynamically allocated WEP keys. This caused a regression when using WEP-LEAP. This patch fixes the regression by keeping track of which key indexes refer to CCMP keys and only using the key miss indication for those.

ath: Convert ath_dbg(bar, ATH_DBG_, to ath_dbg(bar, FOO

2011-12-19T19:35:31Z

Add ATH_DBG_ to macros to shorten the uses and reduce the line count. Coalesce ath_dbg formats. Add missing spaces to coalesced formats. Add missing newline terminations to ath_dbg formats. Align ath_dbg arguments where appropriate. Standardize ath_dbg formats without periods. Signed-off-by: Joe Perches Signed-off-by: John W. Linville

drivers/net: Add export.h to files using EXPORT_SYMBOL/THIS_MODULE

2011-10-31T23:31:08Z

These were getting the macros from an implicit module.h include via device.h, but we are planning to clean that up. Signed-off-by: Paul Gortmaker drivers/net: Add export.h to wireless/brcm80211/brcmfmac/bcmsdh.c This relatively recently added file uses EXPORT_SYMBOL and hence needs export.h included so that it is compatible with the module.h split up work.

ath9k: assign keycache slots to unencrypted stations

2011-04-19T19:38:06Z

Frame filtering relies on having a valid destination index (keycache slot), to keep track of the destination. Assigning a keycache slot (configured to unencrypted, with no key data attached) improves powersave handling in AP mode with no encryption. The dummy keycache entry for a station is cleared, when a real key gets added. Signed-off-by: Felix Fietkau Signed-off-by: John W. Linville
