[MAC80211]: rework key handling This moves all the key handling code out from ieee80211_ioctl.c into key.c and also does the following changes including documentation updates in mac80211.h: 1) Turn off hardware acceleration for keys when the interface is down. This is necessary because otherwise monitor interfaces could be decrypting frames for other interfaces that are down at the moment. Also, it should go some way towards better suspend/resume support, in any case the routines used here could be used for that as well. Additionally, this makes the driver interface nicer, keys for a specific local MAC address are only ever present while an interface with that MAC address is enabled. 2) Change driver set_key() callback interface to allow only return values of -ENOSPC, -EOPNOTSUPP and 0, warn on all other return values. This allows debugging the stack when a driver notices it's handed a key while it is down. 3) Invert the flag meaning to KEY_FLAG_UPLOADED_TO_HARDWARE. 4) Remove REMOVE_ALL_KEYS command as it isn't used nor do we want to use it, we'll use DISABLE_KEY for each key. It is hard to use REMOVE_ALL_KEYS because we can handle multiple virtual interfaces with different key configuration, so we'd have to keep track of a lot of state for this and that isn't worth it. 5) Warn when disabling a key fails, it musn't. 6) Remove IEEE80211_HW_NO_TKIP_WMM_HWACCEL in favour of per-key IEEE80211_KEY_FLAG_WMM_STA to let driver sort it out itself. 7) Tell driver that a (non-WEP) key is used only for transmission by using an all-zeroes station MAC address when configuring. 8) Change the set_key() callback to have access to the local MAC address the key is being added for.

mac80211: use hardware flags for signal/noise units 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.

mac80211: hardware scan rework The scan code in mac80211 makes the software scan assumption in various places. For example, we stop the Tx queue during a software scan so that all the Tx packets will be queued by the stack. We also drop frames not related to scan in the software scan process. But these are not true for hardware scan. Some wireless hardwares (for example iwl3945/4965) has the ability to perform the whole scan process by hardware and/or firmware. The hardware scan is relative powerful in that it tries to maintain normal network traffic while doing a scan in the background. Some drivers (i.e iwlwifi) do provide a way to tune the hardware scan parameters (for example if the STA is associated, what's the max time could the STA leave from the associated channel, how long the scans get suspended after returning to the service channel, etc). But basically this is transparent to the stack. mac80211 should not stop Tx queues or drop Rx packets during a hardware scan. This patch resolves the above problem by spliting the current scan indicator local->sta_scanning into local->sta_sw_scanning and local->sta_hw_scanning. It then changes the scan related code to be aware of hardware scan or software scan in various places. With this patch, iwlwifi performs much better in the scan-while-associated condition and disable_hw_scan=1 should never be required.

[MAC80211]: rework key handling This moves all the key handling code out from ieee80211_ioctl.c into key.c and also does the following changes including documentation updates in mac80211.h: 1) Turn off hardware acceleration for keys when the interface is down. This is necessary because otherwise monitor interfaces could be decrypting frames for other interfaces that are down at the moment. Also, it should go some way towards better suspend/resume support, in any case the routines used here could be used for that as well. Additionally, this makes the driver interface nicer, keys for a specific local MAC address are only ever present while an interface with that MAC address is enabled. 2) Change driver set_key() callback interface to allow only return values of -ENOSPC, -EOPNOTSUPP and 0, warn on all other return values. This allows debugging the stack when a driver notices it's handed a key while it is down. 3) Invert the flag meaning to KEY_FLAG_UPLOADED_TO_HARDWARE. 4) Remove REMOVE_ALL_KEYS command as it isn't used nor do we want to use it, we'll use DISABLE_KEY for each key. It is hard to use REMOVE_ALL_KEYS because we can handle multiple virtual interfaces with different key configuration, so we'd have to keep track of a lot of state for this and that isn't worth it. 5) Warn when disabling a key fails, it musn't. 6) Remove IEEE80211_HW_NO_TKIP_WMM_HWACCEL in favour of per-key IEEE80211_KEY_FLAG_WMM_STA to let driver sort it out itself. 7) Tell driver that a (non-WEP) key is used only for transmission by using an all-zeroes station MAC address when configuring. 8) Change the set_key() callback to have access to the local MAC address the key is being added for.

mac80211: use hardware flags for signal/noise units 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.
