* | iwlwifi: make data frame tracing optionalJohannes Berg2012-10-16
|/ | | | | | | | | | | | | | | | | | | When tracing in iwlwifi, we get all data. Most of the time, we don't need it, and it just takes up a lot of extra space in the trace. Make this optional by recording the data into two separate trace events if it is needed. Without it, record only the content of non-data and EAPOL TX frames. As a result, tracing without the data tracepoints will record meta information including the 802.11 headers for all frames but will not record the contents of data frames to reduce trace overhead.

| * iwlwifi: fix async station command crashJohannes Berg2012-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before Emmanuel's change to use a copy of the command ("iwlwifi: get the correct HCMD in the response handler") the iwl_add_sta_callback() function would have used a random pointer to somewhere when processing responses to an async command, while that wasn't valid data it was at least a valid pointer. Now, the pointer will be NULL in this case, thus crashing. Fix this by exiting the function early if no command is passed back which means it was sent asynchronously.

| * iwlwifi: load firmware in chunksJohannes Berg2012-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of allocating one big chunk of DMA-coherent memory for the firmware and keeping it around, only vmalloc() the firmware and copy it into a single page of DMA-coherent memory for the upload. The advantage is that we don't need DMA memory for the firmware image that is stored while the driver is operating, we only need it while uploading. This will make it easier for the driver to work if the system has fragmented memory. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* | iwlwifi: get the correct HCMD in the response handlerEmmanuel Grumbach2012-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, the response handler of a Host Command got the exact same pointer that was also given to the DMA engine. We almost never need to the Host Command that was sent while handling its response, but when we do need it, we see that the command has been modified. This mystery has been elucidated. The FH (our DMA engine) writes its meta data on the buffer in the DRAM. Of course it copies the buffer to the NIC first. This was known to happen for Tx command, but as a matter of fact, it happens to all TFD brought by the FH which doesn't care much about what it brings from DRAM to internal SRAM. So copy the Host Command to yet another buffer so that we can properly pass the buffer that was sent originally to the fw. Do that only if it was request by the user since very few flows need to get the HCMD sent in the response handler.

By itself though that value is completely worthless since it may be ancient. What really is needed is synchronisation between some device time and the TSF. To clarify this, rename bss_conf.last_tsf to sync_tsf and add sync_device_ts which is obtained from rx_status which gets a new field device_timestamp for this purpose. This is intentionally not using the mactime field since that is used for other things and in IBSS is expected to sync with the IBSS's TSF which isn't necessarily true for the device timestamp. Also, since we have the information and it's useful even before the connection has been established, give all the timing details to the driver before authenticating.

However, when it's connected to two APs, those may be in lockstep, for example if they both have a DTIM interval of 100 TU, then one could be 50 TU after the other, leaving only 50 TU free to be used by scanning. Since we can't know how far apart they are the only option is to restrict to 1/2 of the minium of the two APs. In theory, it would be possible to not use 1/2 of the minimum but take into account that if they have different intervals then there will be a bit more time since they can't be in lockstep, but as they will have 100 TU intervals in practice that complex calculation will probably just result in hard-to-find bugs.

| | | | | | | | | | | | | | | | | | Currently when mac80211 asks to change the interface type, we will accept it for both the BSS and PAN contexts. This is not terribly complicated today, but with the addition of the P2P Device abstraction the PAN context handling will get more complex, so restrict mac_change_interface to the BSS context. Also fix a small locking issue and use is_active instead of the vif pointer to check if the other context is activated, guarding exclusive interface types on the BSS context (IBSS) against the PAN context being used for something else.
