2021-02-02Bluetooth: hci_qca: check for SSR triggered flag while suspendVenkata Lakshmi Narayana Gubba
QCA_IBS_DISABLED flag will be set after memorydump started from controller.Currently qca_suspend() is waiting for SSR to complete based on flag QCA_IBS_DISABLED.Added to check for QCA_SSR_TRIGGERED flag too.

2021-01-29Bluetooth: Add new HCI_QUIRK_NO_SUSPEND_NOTIFIER quirkHans de Goede
Some devices, e.g. the RTL8723BS bluetooth part, some USB attached devices, completely drop from the bus on a system-suspend. These devices will have their driver unbound and rebound on resume (when the dropping of the bus gets detected) and will show up as a new HCI after resume. These devices do not benefit from the suspend / resume handling work done by the hci_suspend_notifier. At best this unnecessarily adds some time to the suspend/resume time. But this may also actually cause problems, if the code doing the driver unbinding runs after the pm-notifier then the hci_suspend_notifier code will try to talk to a device which is now in an uninitialized state. This commit adds a new HCI_QUIRK_NO_SUSPEND_NOTIFIER quirk which allows drivers to opt-out of the hci_suspend_notifier when they know beforehand that their device will be fully re-initialized / reprobed on resume.

2021-01-25Bluetooth: L2CAP: Try harder to accept device not knowing optionsBastien Nocera
The current implementation of L2CAP options negotiation will continue the negotiation when a device responds with L2CAP_CONF_UNACCEPT ("unaccepted options"), but not when the device replies with L2CAP_CONF_UNKNOWN ("unknown options"). Trying to continue the negotiation without ERTM support will allow Bluetooth-capable XBox One controllers (notably models 1708 and 1797) to connect. btmon before patch: > ACL Data RX: Handle 256 flags 0x02 dlen 16 #64 [hci0] 59.182702 L2CAP: Connection Response (0x03) ident 2 len 8 Destination CID: 64 Source CID: 64 Result: Connection successful (0x0000) Status: No further information available (0x0000) < ACL Data TX: Handle 256 flags 0x00 dlen 23 #65 [hci0] 59.182744 L2CAP: Configure Request (0x04) ident 3 len 15 Destination CID: 64 Flags: 0x0000 Option: Retransmission and Flow Control (0x04) [mandatory] Mode: Basic (0x00) TX window size: 0 Max transmit: 0 Retransmission timeout: 0 Monitor timeout: 0 Maximum PDU size: 0 > ACL Data RX: Handle 256 flags 0x02 dlen 16 #66 [hci0] 59.183948 L2CAP: Configure Request (0x04) ident 1 len 8 Destination CID: 64 Flags: 0x0000 Option: Maximum Transmission Unit (0x01) [mandatory] MTU: 1480 < ACL Data TX: Handle 256 flags 0x00 dlen 18 #67 [hci0] 59.183994 L2CAP: Configure Response (0x05) ident 1 len 10 Source CID: 64 Flags: 0x0000 Result: Success (0x0000) Option: Maximum Transmission Unit (0x01) [mandatory] MTU: 1480 > ACL Data RX: Handle 256 flags 0x02 dlen 15 #69 [hci0] 59.187676 L2CAP: Configure Response (0x05) ident 3 len 7 Source CID: 64 Flags: 0x0000 Result: Failure - unknown options (0x0003) 04 . < ACL Data TX: Handle 256 flags 0x00 dlen 12 #70 [hci0] 59.187722 L2CAP: Disconnection Request (0x06) ident 4 len 4 Destination CID: 64 Source CID: 64 > ACL Data RX: Handle 256 flags 0x02 dlen 12 #73 [hci0] 59.192714 L2CAP: Disconnection Response (0x07) ident 4 len 4 Destination CID: 64 Source CID: 64 btmon after patch: > ACL Data RX: Handle 256 flags 0x02 dlen 16 #248 [hci0] 103.502970 L2CAP: Connection Response (0x03) ident 5 len 8 Destination CID: 65 Source CID: 65 Result: Connection pending (0x0001) Status: No further information available (0x0000) > ACL Data RX: Handle 256 flags 0x02 dlen 16 #249 [hci0] 103.504184 L2CAP: Connection Response (0x03) ident 5 len 8 Destination CID: 65 Source CID: 65 Result: Connection successful (0x0000) Status: No further information available (0x0000) < ACL Data TX: Handle 256 flags 0x00 dlen 23 #250 [hci0] 103.504398 L2CAP: Configure Request (0x04) ident 6 len 15 Destination CID: 65 Flags: 0x0000 Option: Retransmission and Flow Control (0x04) [mandatory] Mode: Basic (0x00) TX window size: 0 Max transmit: 0 Retransmission timeout: 0 Monitor timeout: 0 Maximum PDU size: 0 > ACL Data RX: Handle 256 flags 0x02 dlen 16 #251 [hci0] 103.505472 L2CAP: Configure Request (0x04) ident 3 len 8 Destination CID: 65 Flags: 0x0000 Option: Maximum Transmission Unit (0x01) [mandatory] MTU: 1480 < ACL Data TX: Handle 256 flags 0x00 dlen 18 #252 [hci0] 103.505689 L2CAP: Configure Response (0x05) ident 3 len 10 Source CID: 65 Flags: 0x0000 Result: Success (0x0000) Option: Maximum Transmission Unit (0x01) [mandatory] MTU: 1480 > ACL Data RX: Handle 256 flags 0x02 dlen 15 #254 [hci0] 103.509165 L2CAP: Configure Response (0x05) ident 6 len 7 Source CID: 65 Flags: 0x0000 Result: Failure - unknown options (0x0003) 04 . < ACL Data TX: Handle 256 flags 0x00 dlen 12 #255 [hci0] 103.509426 L2CAP: Configure Request (0x04) ident 7 len 4 Destination CID: 65 Flags: 0x0000 < ACL Data TX: Handle 256 flags 0x00 dlen 12 #257 [hci0] 103.511870 L2CAP: Connection Request (0x02) ident 8 len 4 PSM: 1 (0x0001) Source CID: 66 > ACL Data RX: Handle 256 flags 0x02 dlen 14 #259 [hci0] 103.514121 L2CAP: Configure Response (0x05) ident 7 len 6 Source CID: 65 Flags: 0x0000 Result: Success (0x0000) Signed-off-by: Florian Dollinger <dollinger.florian@gmx.de> Co-developed-by: Florian Dollinger <dollinger.florian@gmx.de> Reviewed-by: Luiz Augusto Von Dentz <luiz.von.dentz@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2020-12-18Bluetooth: hci_uart: Fix a race for write_work schedulingClaire Chang
In hci_uart_write_work, there is a loop/goto checking the value of HCI_UART_TX_WAKEUP. If HCI_UART_TX_WAKEUP is set again, it keeps trying hci_uart_dequeue; otherwise, it clears HCI_UART_SENDING and returns. In hci_uart_tx_wakeup, if HCI_UART_SENDING is already set, it sets HCI_UART_TX_WAKEUP, skips schedule_work and assumes the running/pending hci_uart_write_work worker will do hci_uart_dequeue properly. However, if the HCI_UART_SENDING check in hci_uart_tx_wakeup is done after the loop breaks, but before HCI_UART_SENDING is cleared in hci_uart_write_work, the schedule_work is skipped incorrectly. Fix this race by changing the order of HCI_UART_SENDING and HCI_UART_TX_WAKEUP modification.

2020-12-18Bluetooth: btusb: Always fallback to alt 1 for WBSTrent Piepho
When alt mode 6 is not available, fallback to the kernel <= 5.7 behavior of always using alt mode 1. Prior to kernel 5.8, btusb would always use alt mode 1 for WBS (Wide Band Speech aka mSBC aka transparent SCO). In commit baac6276c0a9 ("Bluetooth: btusb: handle mSBC audio over USB Endpoints") this was changed to use alt mode 6, which is the recommended mode in the Bluetooth spec (Specifications of the Bluetooth System, v5.0, Vol 4.B §2.2.1). However, many if not most BT USB adapters do not support alt mode 6. In fact, I have been unable to find any which do. In kernel 5.8, this was changed to use alt mode 6, and if not available, use alt mode 0. But mode 0 has a zero byte max packet length and can not possibly work. It is just there as a zero-bandwidth dummy mode to work around a USB flaw that would prevent device enumeration if insufficient bandwidth were available for the lowest isoc mode supported. In effect, WBS was broken for all USB-BT adapters that do not support alt 6, which appears to nearly all of them. Then in commit 461f95f04f19 ("Bluetooth: btusb: USB alternate setting 1 for WBS") the 5.7 behavior was restored, but only for Realtek adapters. I've tested a Broadcom BRCM20702A and CSR 8510 adapter, both work with the 5.7 behavior and do not with the 5.8. So get rid of the Realtek specific flag and use the 5.7 behavior for all adapters as a fallback when alt 6 is not available. This was the kernel's behavior prior to 5.8 and I can find no adapters for which it is not correct. And even if there is an adapter for which this does not work, the current behavior would be to fall back to alt 0, which can not possibly work either, and so is no better.
