* mac80211: split ieee80211_txrx_dataJohannes Berg2008-03-061-12/+12
| | | | | | | | Split it into ieee80211_tx_data and ieee80211_rx_data to clarify usage/flag usage and remove the stupid union thing. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: split RX_DROPJohannes Berg2008-02-291-1/+1
| | | | | | | | | | Some instances of RX_DROP mean that the frame was useless, others mean that the frame should be visible in userspace on "cooked" monitor interfaces. This patch splits up RX_DROP and changes each instance appropriately. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: split ieee80211_txrx_resultJohannes Berg2008-02-291-8/+8
| | | | | | | | | | The _DROP result will need to be split in the RX path but not in the TX path, so for preparation split up the type into two types, one for RX and one for TX. Also make sure (via sparse) that they cannot be confused. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: move tx crypto decisionJohannes Berg2008-01-281-10/+0
| | | | | | | | | | | | | | This patch moves the decision making about whether a frame is encrypted with a certain algorithm up into the TX handlers rather than having it in the crypto algorithm implementation. This fixes a problem with the radiotap injection code where injecting a non-data packet and requesting encryption could end up asking the driver to encrypt a packet without giving it a key.

* mac80211: rate limit wep decrypt failed messagesAdel Gadllah2007-11-291-1/+2
| | | | | | | | The attached patch rate limits "WEP decrypt failed (ICV)" to avoid flooding the logfiles. Signed-off-by: Adel Gadllah <adel.gadllah@gmx.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: make "decrypt failed" messages conditional upon MAC80211_DEBUGJohn W. Linville2007-11-101-0/+2
| | | | | | | | | | | | | | Make "decrypt failed" and "have no key" debugging messages compile conditionally upon CONFIG_MAC80211_DEBUG. They have been useful for finding certain problems in the past, but in many cases they just clutter a user's logs. A typical example is an enviornment where multiple SSIDs are using a single BSSID but with different protection schemes or different keys for each SSID. In such an environment these messages are just noise. Let's just leave them for those interested enough to turn-on debugging. Signed-off-by: John W. Linville <linville@tuxdriver.com>
* [PATCH] Fix breakage after SG cleanupsRalf Baechle2007-10-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | Commits 58b053e4ce9d2fc3023645c1b96e537c72aa8d9a ("Update arch/ to use sg helpers") 45711f1af6eff1a6d010703b4862e0d2b9afd056 ("[SG] Update drivers to use sg helpers") fa05f1286be25a8ce915c5dd492aea61126b3f33 ("Update net/ to use sg helpers") converted many files to use the scatter gather helpers without ensuring that the necessary headerfile <linux/scatterlist> is included. This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke. Instead of increasing the header file spider web I choose to include <linux/scatterlist.h> directly into the affectes files.

* [PATCH] mac80211: consolidate encryptionJohannes Berg2007-10-101-3/+54
| | | | | | | | | | Currently we run through all crypto handlers for each transmitted frame although we already know which one will be used. This changes the code to invoke only the needed handler. It also moves the wep code into wep.c. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* [PATCH] mac80211: consolidate decryptionJohannes Berg2007-10-101-5/+29
| | | | | | | | | | | | Currently, we run through all three crypto algorithms for each received frame even though we have previously determined which key we have and as such already know which algorithm will be used. Change it to invoke only the needed function. Also move the WEP decrypt handler to wep.c so that fewer functions need to be non-static.

* [MAC80211]: embed key conf in key, fix driver interfaceJohannes Berg2007-10-101-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch embeds the struct ieee80211_key_conf into struct ieee80211_key and thus avoids allocations and having data present twice. This required some more changes: 1) The removal of the IEEE80211_KEY_DEFAULT_TX_KEY key flag. This flag isn't used by drivers nor should it be since we have a set_key_idx() callback. Maybe that callback needs to be extended to include the key conf, but only a driver that requires it will tell. 2) The removal of the IEEE80211_KEY_DEFAULT_WEP_ONLY key flag. This flag is global, so it shouldn't be passed in the key conf structure. Pass it to the function instead. Also, this patch removes the AID parameter to the set_key() callback because it is currently unused and the hardware currently cannot know about the AID anyway. I suspect this was used with some hardware that actually selected the AID itself, but that functionality was removed. Additionally, I've removed the ALG_NULL key algorithm since we have ALG_NONE.
