| * mac80211: use hardware flags for signal/noise unitsBruno Randolf2008-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | trying to clean up the signal/noise code. the previous code in mac80211 had confusing names for the related variables, did not have much definition of what units of signal and noise were provided and used implicit mechanisms from the wireless extensions. this patch introduces hardware capability flags to let the hardware specify clearly if it can provide signal and noise level values and which units it can provide. this also anticipates possible new units like RCPI in the future. for signal: IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW for noise we currently only have dBm: IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has to provide the maximum value (max_signal) it reports in order for applications to make sense of the signal values. i tried my best to find out for each driver what it can provide and update it but i'm not sure (?) for some of them and used the more conservative guess in doubt. this can be fixed easily after this patch has been merged by changing the hardware flags of the driver.

| * iwl3945: do not delay hardware scan if it is a direct scanBill Moss2008-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iwl3945 <---> mac80211 <----> wpa_supplicant <---> NetworkManager When a hardware scan is completed and another scan is requested in less than two seconds, iwlwifi will not do the second scan and will pass the error code -EAGAIN back to mac80211 where it quickly dies. The error code is not passed along to the calling program wpa_supplicant. After a timeout, wpa_supplicant will just give up but it will not know why the scan failed. This is a weakness in the design. I ran into this issue when I was trying to figure out why it takes more an a minute for NetworkManager to connect after Networking has been disabled and then re-enabled. I found a good deal of unnecessary work being done because mac80211 requests authentication when the interface is not configured, the ANY mode. I created an experimental passive (NOTANY) mode for mac80211 to eliminate this case. Then NetworkManager became so fast that I ran into the iwlwifi 2 second delay next scan issue which we are discussing. The patch resolves the problem by bypassing the delay if the scan request is a direct scan. It should do less harm to the hardware.

| * mac80211: proper STA info lockingJohannes Berg2008-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed earlier, we can unify locking in struct sta_info and use just a single spinlock protecting all members of the structure that need protection. Many don't, but one of the especially bad ones is the 'flags' member that can currently be clobbered when RX and TX is being processed on different CPUs at the same time. Because having four spinlocks for different, mostly exclusive parts of a single structure is overkill, this patch also kills the ampdu and mesh plink spinlocks and uses just a single one for everything. Because none of the spinlocks are nested, this is safe. It remains to be seen whether or not we should make the sta flags use atomic bit operations instead, for now though this is a safe thing and using atomic operations instead will be very simple using the new static inline functions this patch introduces for accessing sta->flags. Since spin_lock_bh() is used with this lock, there shouldn't be any contention even if aggregation is enabled at around the same time as both requires frame transmission/reception which is in a bh context.
