Tx pending flag is set to true when HOST IBS state is AWAKE or AWAKEING. If IBS state is ASLEEP, then Tx clock is already voted off. To optimize further directly calling serial_clock_vote() instead of qca_wq_serial_tx_clock_vote_off(), at this point of qca_suspend() already data is sent out. No need to wake up hci to send data.

In some version of WCN399x, SoC idle timeout is configured as 80ms instead of 20ms or 40ms. To honor all the SoC's supported in the driver increasing SoC idle timeout to 200ms. Fixes: 41d5b25f ("Bluetooth: hci_qca: add PM support") Signed-off-by:

Alain Michaud authored
This change adds support for reporting the BT_PKT_STATUS to the socket CMSG data to allow the implementation of a packet loss correction on erroneous data received on the SCO socket. The patch was partially developed by Marcel Holtmann and validated by Hsin-yu Chao. Signed-off-by:

Use device_init_wakeup to allow the Bluetooth dev to wake the system from suspend. Currently, the device can wake the system but no power/wakeup entry is created in sysfs to allow userspace to disable wakeup. Signed-off-by:

Use the parent device's power/wakeup to control whether we support remote wake. If remote wakeup is disabled, Bluetooth will not enable scanning for incoming connections. Signed-off-by:

Set the correct parent dev when registering hdev. This allows userspace tools to find the parent device (for example, to set the power/wakeup property). Before this change, the path was /sys/devices/virtual/bluetooth/hci0 and after this change, it looks more like: /sys/bus/mmc/devices/mmc1:0001/mmc1:0001:2/bluetooth/hci0 Signed-off-by:

Due to race conditions between qca_hw_error and qca_controller_memdump during SSR timeout,the same pointer is freed twice. This results in a double free. Now a lock is acquired before checking the stauts of SSR state. Fixes: d841502c ("Bluetooth: hci_qca: Collect controller memory dump during SSR") Signed-off-by:

It is preferable to allow suspend even when Bluetooth has problems preparing for sleep. When Bluetooth fails to finish preparing for suspend, log the error and allow the suspend notifier to continue instead. To also make it clearer why suspend failed, change bt_dev_dbg to bt_dev_err when handling the suspend timeout. Fixes: dd522a74 ("Bluetooth: Handle LE devices during suspend") Reported-by:

qca_suspend() calls serdev_device_wait_until_sent() regardless of whether a transfer is pending. While it does no active harm since the function should return immediately it makes the code more confusing. Add a flag to track whether a transfer is pending and only call serdev_device_wait_until_sent() is needed. Signed-off-by:

qca_suspend() removes the vote for the UART TX clock after writing an IBS sleep request to the serial buffer. This is not a good idea since there is no guarantee that the request has been sent at this point. Instead remove the vote after successfully entering IBS sleep. This also fixes the issue of the vote being removed in case of an aborted suspend due to a failure of entering IBS sleep. Fixes: 41d5b25f ("Bluetooth: hci_qca: add PM support") Signed-off-by:

Matthias Kaehlcke authored
The serial clocks should be on when there is a vote for at least one of the clocks (RX or TX), and off when there is no 'on' vote. The current logic to determine the combined state is a bit redundant in the code paths for different types of votes, use a single statement in the common path instead. Signed-off-by:

When a function like devm_clk_get_optional() function returns both error pointers on error and NULL then the NULL return means that the optional feature is deliberately disabled. It is a special sort of success and should not trigger an error message. The surrounding code should be written to check for NULL and not crash. On the other hand, if we encounter an error, then the probe from should clean up and return a failure. In this code, if devm_clk_get_optional() returns an error pointer then the kernel will crash inside the call to: clk_set_rate(qcadev->susclk, SUSCLK_RATE_32KHZ); The error handling must be updated to prevent that.

When running with conntrack rules, the dropped overlap fragments may cause EPERM to be returned to sendto. Instead of completely failing, just ignore those errors and continue. If this causes packets with overlap fragments to be dropped as expected, that is okay. And if it causes packets that are expected to be received to be dropped, which should not happen, it will be detected as failure. Signed-off-by:

This reverts commit de058420. There is no actual tipc_node refcnt leak as stated in the above commit. The refcnt is hold carefully for the case of an asynchronous decryption (i.e. -EINPROGRESS/-EBUSY and skb = NULL is returned), so that the node object cannot be freed in the meantime. The counter will be re-balanced when the operation's callback arrives with the decrypted buffer if any. In other cases, e.g. a synchronous crypto the counter will be decreased immediately when it is done. Now with that commit, a kernel panic will occur when there is no node found (i.e. n = NULL) in the 'tipc_rcv()' or a premature release of the node object. This commit solves the issues by reverting the said commit, but keeping one valid case that the 'skb_linearize()' is failed. Acked-by:

Make sample_cnt volatile to fix possible selftests failure due to compiler optimization preventing latest sample_cnt value to be visible to main thread. sample_cnt is incremented in background thread, which is then joined into main thread. So in terms of visibility sample_cnt update is ok. But because it's not volatile, compiler might make optimizations that would prevent main thread to see latest updated value. Fix this by marking global variable volatile. Fixes: cb1c9ddd ("selftests/bpf: Add BPF ringbuf selftests") Signed-off-by:
