Revert "Bluetooth: btusb: driver to enable the usb-wakeup feature"

2019-09-19T07:11:06+00:00

commit 1ffdb51f28e8ec6be0a2b812c1765b5cf5c44a8f upstream. This reverts commit a0085f2510e8976614ad8f766b209448b385492f. This commit has caused regressions in notebooks that support suspend to idle such as the XPS 9360, XPS 9370 and XPS 9380. These notebooks will wakeup from suspend to idle from an unsolicited advertising packet from an unpaired BLE device. In a bug report it was sugggested that this is caused by a generic lack of LE privacy support. Revert this commit until that behavior can be avoided by the kernel.

Bluetooth: btqca: Add a short delay before downloading the NVM

2019-09-10T09:35:14+00:00

[ Upstream commit 8059ba0bd0e4694e51c2ee6438a77b325f06c0d5 ] On WCN3990 downloading the NVM sometimes fails with a "TLV response size mismatch" error: [ 174.949955] Bluetooth: btqca.c:qca_download_firmware() hci0: QCA Downloading qca/crnv21.bin [ 174.958718] Bluetooth: btqca.c:qca_tlv_send_segment() hci0: QCA TLV response size mismatch It seems the controller needs a short time after downloading the firmware before it is ready for the NVM. A delay as short as 1 ms seems sufficient, make it 10 ms just in case. No event is received during the delay, hence we don't just silently drop an extra event.

Bluetooth: hci_uart: check for missing tty operations

2019-08-04T07:29:39+00:00

commit b36a1552d7319bbfd5cf7f08726c23c5c66d4f73 upstream. Certain ttys operations (pty_unix98_ops) lack tiocmget() and tiocmset() functions which are called by the certain HCI UART protocols (hci_ath, hci_bcm, hci_intel, hci_mrvl, hci_qca) via hci_uart_set_flow_control() or directly. This leads to an execution at NULL and can be triggered by an unprivileged user. Fix this by adding a helper function and a check for the missing tty operations in the protocols code. This fixes CVE-2019-10207. The Fixes: lines list commits where calls to tiocm[gs]et() or hci_uart_set_flow_control() were added to the HCI UART protocols.
