Unfortunately the PCI id is the same in hw1.0 and hw2.0 so ath10k tries to use hw1.0 boards anyway. But without hw1.0 workarounds in place ath10k just crashes horribly. To avoid using hw1.0 boards at all add a chip id detection and fail the probe if hw1.0 is detected: [ 5265.786408] ath10k: ERROR: qca988x hw1.0 is not supported [ 5265.786497] ath10k: Unsupported chip id 0x043200ff [ 5265.786574] ath10k: could not register driver core (-95) [ 5265.793191] ath10k_pci: probe of 0000:02:00.0 failed with error -95 Also add a warning if there's an unknown chip id but continue the boot process normally anyway.

In that case the outer while() would not terminate and run again, and again. This could happen especially on a slow host system. This could lead to a system freeze during heavy traffic.

From 12acbc43c1c302022984bf0af89ac5f0a24b133a Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Fri, 13 Sep 2013 14:16:55 +0200 Subject: [PATCH 054/227] ath10k: simplify HTC command submitting The patch removes HTC endpoint tx workers in favour of direct command submission. This makes a lot more sense for data path. mac80211 queues are effectively stopped/woken up in a more timely fashion preventing build up of frames. It's possible to push more traffic than the device/system is able to handle and have no hiccups or performance degradation with UDP traffic. WMI commands will now report errors properly and possibly block as they actively can wait for tx credits to become available.

The kernel will stay away from the device and does not allow any further modifications of the device states. The existing raw flag is not used since it has a bit of unclear meaning due to its legacy. Using a new flag makes the code clearer. A device with the user channel flag set can still be enumerate using the legacy API, but it does not longer enumerate using the new management interface used by BlueZ 5 and beyond.

The application gains exclusive access to this device and forces the kernel to stay away and not manage it. In case of the management interface it will actually hide the device. Such operation is useful for security testing tools that need to operate underneath the Bluetooth stack and need full control over a device. The advantage here is that the kernel still provides the service of hardware abstraction and HCI level access. The use of Bluetooth drivers for hardware access also means that sniffing tools like btmon or hcidump are still working and the whole set of transaction can be traced with existing tools. With the new channel it is possible to send HCI commands, ACL and SCO data packets and receive HCI events, ACL and SCO packets from the device. The format follows the well established H:4 protocol. The new HCI user channel can only be established when a device has been through its setup routine and is currently powered down. This is enforced to not cause any problems with current operations. In addition only one user channel per HCI device is allowed. It is exclusive access for one user application. Access to this channel is limited to process with CAP_NET_RAW capability. Using this new facility does not require any external library or special ioctl or socket filters. Just create the socket and bind it. After that the file descriptor is ready to speak H:4 protocol. struct sockaddr_hci addr; int fd; fd = socket(AF_BLUETOOTH, SOCK_RAW, BTPROTO_HCI); memset(&addr, 0, sizeof(addr)); addr.hci_family = AF_BLUETOOTH; addr.hci_dev = 0; addr.hci_channel = HCI_CHANNEL_USER; bind(fd, (struct sockaddr *) &addr, sizeof(addr)); The example shows on how to create a user channel for hci0 device. Error handling has been left out of the example. However with the limitations mentioned above it is advised to handle errors. Binding of the user cahnnel socket can fail for various reasons. Specifically if the device is currently activated by BlueZ or if the access permissions are not present.

This patch adds the functionality to define inline to create either a BR/EDR or an AMP controller. In addition the client will be informed which HCI controller index it got assigned. That is especially useful for automated end-to-end testing. To keep backwards compatibility with existing userspace, the command for creating a controller type needs to be send right after opening the device node. If the command is not send, it defaults back to automatically creating a BR/EDR controller.

The command depends on the LE setting being enabled first and will return a "rejected" response otherwise. The patch also adds safeguards so that there will ever only be one set_le or set_advertising command pending per adapter. The response handling and new_settings event sending is done in an asynchronous request callback, meaning raw HCI access from user space to enable advertising (e.g. hciconfig leadv) will not trigger the new_settings event. This is intentional since trying to support mixed raw HCI and mgmt access would mean adding extra state tracking or new helper functions, essentially negating the benefit of using the asynchronous request framework. The HCI_LE_ENABLED and HCI_LE_PERIPHERAL flags however are updated correctly even with raw HCI access so this will not completely break subsequent access over mgmt.

This leads to re-aligning in mac80211 which in turn leads to poor CPU cache behaviour on some machines. Since HW doesn't allow to change payload offset properly the solution is to force HW to decap in Native Wifi mode which always has 24-bytes long 802.11 header (even for QoS frames). This means IP frame is properly aligned in this decap mode.

If the IE is malformed in the beacons from some APs [1], the HW locks up. In AP mode, a beacon stuck would happen and in client mode, a disconnection usually is the result. To fix this issue, set the AR_PCU_MISC_MODE2_CFP_IGNORE to ignore the CFP IE in beacons - this is applicable for all chips. For AP mode, if this issue happens, the NAV is also corrupted and has to be reset - this will be done in a subsequent patch.

Due to this limitation RT3593 based PCIe cards are not working correctly. On PCIe cards band selection is controlled via GPIO #8 which is identical to the USB devices. The LNA PE control is slightly different, all LNA PEs are controlled by GPIO #4. Update the code to configure the GPIO_CTRL register correctly on PCIe devices.

This adds the necessary calls to ensure that any previously scheduled work is completed before attempting to call hci_dev_do_open. This patch fixes a race with old user space versions where we might receive a HCIDEVUP ioctl before the setup procedure has been completed. When that happens the setup procedures callback may fail early and leave the device in an inconsistent state, causing e.g. the setup callback to be (incorrectly) called more than once.

This patch add the new flag and updates the relevant places to test against it instead of using lmp_bredr_enabled. The flag is by default enabled when registering an adapter and only cleared if necessary once the local features have been read during the HCI init procedure. We cannot completely block BR/EDR usage in case user space uses raw HCI sockets but the patch tries to block this in places where possible, such as the various BR/EDR specific ioctls.

This can be convenient when one wants to make a dual-mode controller behave like a single-mode one. The command is only available for dual-mode controllers and requires that LE is enabled before using it. The BR/EDR setting can be enabled at any point, however disabling it requires the controller to be powered off (otherwise a "rejected" response will be sent). Disabling the BR/EDR setting will automatically disable all other BR/EDR related settings.

There are two types or random addresses, one is static and the other private. Since the random private addresses require special privacy feature to be supported, the configuration of these two are kept separate. This command allows for setting the static random address. It is only supported on controllers with LE support. The static random address is suppose to be valid for the lifetime of the controller or at least until the next power cycle. To ensure such behavior, setting of the address is limited to when the controller is powered off. The special BDADDR_ANY address (00:00:00:00:00:00) can be used to disable the static address. This is also the default value.
