Bluetooth: hci_bcm: Handle specific unknown packets after firmware loading

2019-12-05T08:20:39Z

[ Upstream commit 22bba80500fdf624a7cfbb65fdfa97a038ae224d ] The Broadcom controller on aries S5PV210 boards sends out a couple of unknown packets after the firmware is loaded. This will cause logging of errors such as: Bluetooth: hci0: Frame reassembly failed (-84) This is probably also the case with other boards, as there are related Android userspace patches for custom ROMs such as https://review.lineageos.org/#/c/LineageOS/android_system_bt/+/142721/ Since this appears to be intended behaviour, treated them as diagnostic packets.

Bluetooth: Fix invalid-free in bcsp_close()

2019-12-01T08:17:35Z

commit cf94da6f502d8caecabd56b194541c873c8a7a3c upstream. Syzbot reported an invalid-free that I introduced fixing a memleak. bcsp_recv() also frees bcsp->rx_skb but never nullifies its value. Nullify bcsp->rx_skb every time it is freed.

Bluetooth: btrsi: fix bt tx timeout issue

2019-11-20T17:47:42Z

[ Upstream commit 7cbfd1e2aad410d96fa6162aeb3f9cff1fecfc58 ] observed sometimes data is coming with unaligned address from kernel BT stack. If unaligned address is passed, some data in payload is stripped when packet is loading to firmware and this results, BT connection timeout is happening. sh# hciconfig hci0 up Can't init device hci0: hci0 command 0x0c03 tx timeout Fixed this by moving the data to aligned address.

Bluetooth: btrtl: HCI reset on close for Realtek BT chip

2019-10-01T06:26:11Z

[ Upstream commit 7af3f558aca74f2ee47b173f1c27f6bb9a5b5561 ] Realtek RTL8822BE BT chip on ASUS X420FA cannot be turned on correctly after on-off several times. Bluetooth daemon sets BT mode failed when this issue happens. Scanning must be active while turning off for this bug to be hit. bluetoothd[1576]: Failed to set mode: Failed (0x03) If BT is turned off, then turned on again, it works correctly again. According to the vendor driver, the HCI_QUIRK_RESET_ON_CLOSE flag is set during probing. So, this patch makes Realtek's BT reset on close to fix this issue.

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

2019-09-19T07:09:40Z

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

2019-09-10T09:33:43Z

[ 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

2019-08-04T07:30:55Z

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.
