During mesh setup, use NL80211_MESH_SETUP_USERSPACE_AUTH flag to create a secure mesh and route management frames to userspace. Also, NL80211_CMD_GET_WIPHY now returns a flag NL80211_SUPPORT_MESH_AUTH if the wiphy's mesh implementation supports routing of mesh auth frames to userspace. This is useful for forward compatibility between old kernels and new userspace tools. Signed-off-by:

iwl4965_rate_control_register() prints a message at KERN_ERR level. It looks like it's just a debugging message, so pr_err() seems to be overdone. But none of the similar functions in drivers/net/wireless print a message, so let's just drop it. Signed-off-by:

rx should only be enabled after enough rx buffers have been given to the hardware, however ath_rx_buf_link was calling ath9k_hw_rxena after every single added buffer. Fix this by calling ath9k_hw_rxena directly from the rx tasklet after completion instead. Signed-off-by:

Before calling host_to_card() to send the cmd to firmware, we use skb_push() to add 4 bytes SDIO interface header at the start of the data buffer. Since cmd_skb data structure will be re-used at a later time, we need to restore its headroom by removing the 4 bytes header. Signed-off-by:

The problem is that when the attenuation is increased, the rate will start to drop from MCS7 -> MCS6, and finally will see MCS1 -> CCK_11Mbps. When the rate is changed b/w CCK and OFDM, it will use register desired_scale to calculate how much tx gain need to change. The output power with the same tx gain for CCK and OFDM modulated signals are different. This difference is constant for AR9280 but not AR9285/AR9271. It has different PA architecture a constant. So it should be calibrated against this PA characteristic. The driver has to read the calibrated values from EEPROM and set the tx power registers accordingly. Signed-off-by:

In a highly noisy environment, the tx rate of the driver drops and the application slows down since it has not yet received ACKs for the frames already queued in the hardware. Since this ACK may take more than 100ms, stopping the dev queues for entering PS at this stage breaks applications, WMM test cases in my testing. If there are frames already pending in the tx queue, postponing the PS logic helps to avoid redundant queue stops. When power save is enabled by default and in a noisy environment, this API certainly helps in improving the average throughput. Signed-off-by:

If we maintain API properly, then there isn't really a reason to warn about this since we'll just be adding things that are safe to ignore, so downgrade the warning to debug info level. Signed-off-by:

There's no need to keep both normal and BT statistics versions around all the time in memory when we only use a subset of both. So keep only the subsets that we need in memory, depending on the debug config). Also, in doing so, we can remove all the calls to iwl_bt_statistics() in the driver as we'll just access the copied statistics now. Finally, also remove this call from the one place where it might still be needed and automatically detect what kind of statistics the device is sending based on their size. This way, we don't need to keep track of which devices do what any more, which is good since this is subject to change based on the ucode version (as some ucode even for non-BT devices will in fact use BT statistics). Warn upon encountering a statistics command from the ucode that isn't known, so we will find such issues earlier in the future. Signed-off-by:

If change_interface gets invoked during a firmware restart, it may crash; prevent that from happening by checking if ctx->vif is assigned. Additionally, in my initial commit I forgot to set the vif->p2p variable correctly, so fix that too. Cc: stable@kernel.org [2.6.38+] Signed-off-by:

The microcode may sometimes reject TX frames when on a radar channel even after we associated as it clears information during association and needs to receive a new beacon before allowing that channel again. This manifests itself as a TX status value of TX_STATUS_FAIL_PASSIVE_NO_RX. So in this case, stop the corresponding queue and give the frame back to mac80211 for retransmission. We start the queue again when a beacon from the AP is received which will make the regulatory enforcement in the device allow transmitting again. Signed-off-by:

We have no other option but to inform userspace that we have queued up their regulatory hint request when we are given one given that nl80211 operates atomically on user requests. The best we can do is accept the request, and add a delayed work item for processing failure and cancel it if we succeeed. Upon failure we restore the regulatory settings and ignore the user input.

When we restore regulatory settings its possible CRDA will not reply because of a bogus user entry. In this case the bogus entry will prevent any further processing on cfg80211 for regulatory domains even if we restore regulatory settings. To prevent this we suck out all pending requests when restoring regulatory settings and add them back into the queue after we have queued up the reset work. The impact of not having this applied is that a user with privileges can issue a userspace regulatory hint while we are disasocciating and this would prevent any further processing of regulatory domains.

This generates a massive reduction in module size: with debug: text data bss dec hex filename 670300 13136 420 683856 a6f50 iwlagn.ko (before) 388347 13136 408 401891 621e3 iwlagn.ko (after) without debug: text data bss dec hex filename 528575 13072 420 542067 84573 iwlagn.ko (before) 294192 13072 408 307672 4b1d8 iwlagn.ko (after) This also removes all the IO debug functionality since it can easily be replaced by tracing, and makes the code unnecessarily complex. I haven't done any CPU utilisation measurements, but given that the hotpaths don't use much IO it is not likely to have a negative impact; in fact, the size reduction will reduce cache pressure which possibly improves performance. Finally, an unused function or two were removed. Signed-off-by:

Devices newer than 4965 don't actually send two different versions of the ALIVE command, so we always had a bug here since before this patch we copy more data than we got. Remove the iwl_init_alive_resp struct and don't use it. Since we also really don't need to track all the data received in ALIVE as we only use the error and log event tables later, we can also save space by just keeping those and not more data around in memory.

Some new devices and microcode files will a greater variety of features, so the TLV-per-feature approach we took before will quickly make things harder to manage and increase the file size. Add a new TLV that has feature flags. Currently, it will contain: 1) a PAN feature flag, which moves from a separate TLV 2) a new BT stats bit that indicates whether the microcode image uses bluetooth statistics 3) a new MFP flag for management frame protection which can be enabled once the device/microcode supports it Signed-off-by:
