So far struct clocksource acted as the interface between time/timekeeping.c and hardware. This patch generalizes the concept so that a similar interface can also be used in other contexts. For that it introduces new structures and related functions *without* touching the existing struct clocksource. The reasons for adding these new structures to clocksource.[ch] are * the APIs are clearly related * struct clocksource could be cleaned up to use the new structs * avoids proliferation of files with similar names (timesource.h? timecounter.h?) As outlined in the discussion with John Stultz, this patch adds * struct cyclecounter: stateless API to hardware which counts clock cycles * struct timecounter: stateful utility code built on a cyclecounter which provides a nanosecond counter * only the function to read the nanosecond counter; deltas are used internally and not exposed to users of timecounter The code does no locking of the shared state. It must be called at least as often as the cycle counter wraps around to detect these wrap arounds. Both is the responsibility of the timecounter user.

Single-thread access must be ensured for ICH8 NVM and PHY operations. This synchronization is provided by the nvm_mutex. To assist in understanding the contexts from which this code could be reached, a WARN was output if the mutex was not going to be immediately acquirable (if !mutex_trylock()). The code has now been optimized, and we have verified that the few remaining mutex contentions are reasonable and non-blocking, and it is time to remove the mutex_trylock() and WARN messages.

The test to find out if we have FAT channels do not consider that the value of regulatory_bands for the 5000 series is larger than its eeprom size. Using the eeprom size is strange in itself.

It appears that you can completely mess up mac80211 in IBSS mode by sending it a disassoc or deauth: it'll stop queues and do a lot more but not ever do anything again.

There's no need to create a BSS struct only to pass it to ieee80211_sta_join_ibss, so refactor this function into __ieee80211_sta_join_ibss which takes all the relevant paramters, and ieee80211_sta_join_ibss which takes a BSS struct (used when joining an IBSS that already has other members).

This patch adds basic scan capability to cfg80211/nl80211 and changes mac80211 to use it. The BSS list that cfg80211 maintains is made driver-accessible with a private area in each BSS struct, but mac80211 doesn't yet use it. That's another large project.

As far as I can tell, there are possible lockups because both the RX session_timer and TX addba_resp_timer are del_timer_sync'ed under the sta spinlock which both timer functions take. Additionally, the TX agg code seems to leak memory when TX aggregation is not disabled before the sta_info is freed. Fix this by making the free code a little smarter in the RX agg case, and actually make the sta_info_destroy code free the TX agg info in the TX agg case. We won't notify the peer, but it'll notice something is wrong anyway, and normally this only happens after we've told it in some other way we will no longer talk to it.

When disabling TX aggregation because it was rejected or from the timer (it was not accepted), there is a window where we first set the state to operation, unlock, and then undo the whole thing. Avoid that by splitting up the stop function. Also get rid of the pointless sta_info indirection in the timer. Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W.

Doing so would be an MLME protocol violation when the peer disabled the aggregation session. Quick driver review indicates that there are error codes passed all over the drivers but cannot ever be nonzero except in error conditions that would indicate mac80211 bugs.

We can only support aggregation on AP/STA right now. HT isn't defined for IBSS, WDS or MESH.
