2011-09-30mac80211: implement uAPSDJohannes Berg1-1/+1
Add uAPSD support to mac80211. This is probably not possible with all devices, so advertising it with the cfg80211 flag will be left up to drivers that want it. Due to my previous patches it is now a fairly straight-forward extension. Drivers need to have accurate TX status reporting for the EOSP frame. For drivers that buffer themselves, the provided APIs allow releasing the right number of frames, but then drivers need to set EOSP and more-data themselves. This is documented in more detail in the new code itself. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: John W. Linville <[email protected]>

2011-09-21iwlegacy: do not use interruptible waitsStanislaw Gruszka5-13/+13
iwlegacy version of fix: commit effd4d9aece9184f526e6556786a94d335e38b71 Author: Johannes Berg <[email protected]> Date: Thu Sep 15 11:46:52 2011 -0700 iwlagn: do not use interruptible waits Since the dawn of its time, iwlwifi has used interruptible waits to wait for synchronous commands and firmware loading. This leads to "interesting" bugs, because it can't actually handle the interruptions; for example when a command sending is interrupted it will assume the command completed fully, and then leave it pending, which leads to all kinds of trouble when the command finishes later. Since there's no easy way to gracefully deal with interruptions, fix the driver to not use interruptible waits. This at least fixes the error iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD' I have seen in P2P testing, but it is likely that there are other errors caused by this.

2011-09-21iwlegacy: fix command queue timeoutStanislaw Gruszka1-0/+2
iwlegacy version of fix: commit 282cdb325aea4ebbc42ce753b47cc96145eb54bc Author: Johannes Berg <[email protected]> Date: Mon Sep 12 12:09:10 2011 -0700 iwlagn: fix command queue timeout If the command queue is constantly busy, which can happen in P2P, the hangcheck timer will frequently find a command in it and will eventually reset the device because nothing sets the timestamp for this queue when commands are processed. Fix this by setting the timestamp when a command completes. iwlegacy does not support P2P, but this patch fix possible unneeded hardware resets, hence is needed.

All these are instances of #define NAME value; or #define NAME(params_opt) value; These of course fail to build when used in contexts like if(foo $OP NAME) while(bar $OP NAME) and may silently generate the wrong code in contexts such as foo = NAME + 1; /* foo = value; + 1; */ bar = NAME - 1; /* bar = value; - 1; */ baz = NAME & quux; /* baz = value; & quux; */ Reported on comp.lang.c, Message-ID: <ab0d55fe-25e5-482b-811e-c475aa6065c3@c29g2000yqd.googlegroups.com> Initial analysis of the dangers provided by Keith Thompson in that thread. There are many more instances of more complicated macros having unnecessary trailing semicolons, but this pile seems to be all of the cases of simple values suffering from the problem.

2011-07-08mac80211: fix TKIP races, make API easier to useJohannes Berg1-2/+1
Our current TKIP code races against itself on TX since we can process multiple packets at the same time on different ACs, but they all share the TX context for TKIP. This can lead to bad IVs etc. Also, the crypto offload helper code just obtains the P1K/P2K from the cache, and can update it as well, but there's no guarantee that packets are really processed in order. To fix these issues, first introduce a spinlock that will protect the IV16/IV32 values in the TX context. This first step makes sure that we don't assign the same IV multiple times or get confused in other ways. Secondly, change the way the P1K cache works. I add a field "p1k_iv32" that stores the value of the IV32 when the P1K was last recomputed, and if different from the last time, then a new P1K is recomputed. This can cause the P1K computation to flip back and forth if packets are processed out of order. All this also happens under the new spinlock. Finally, because there are argument differences, split up the ieee80211_get_tkip_key() API into ieee80211_get_tkip_p1k() and ieee80211_get_tkip_p2k() and give them the correct arguments.
