Bluetooth: btrtl: Restore old logic to assume firmware is already loaded

2019-03-10T06:09:01+00:00

commit 00df214b1faae520880cc5c57e206f21239ef741 upstream. Realtek bluetooth may not work after reboot: [ 12.446130] Bluetooth: hci0: RTL: rtl: unknown IC info, lmp subver a99e, hci rev 826c, hci ver 0008 This is a regression introduced by commit 26503ad25de8 ("Bluetooth: btrtl: split the device initialization into smaller parts"). The new logic errors out early when no matching IC info can be found, in this case it means the firmware is already loaded. So let's assume the firmware is already loaded when we can't find matching IC info, like the old logic did.

USB: serial: cp210x: fix GPIO in autosuspend

2019-03-10T06:09:01+00:00

commit 7b0b644b9aa2de5032db0f468fddca091d0b7b90 upstream. Current GPIO code in cp210x fails to take USB autosuspend into account, making it practically impossible to use GPIOs with autosuspend enabled without user configuration. Fix this like for ftdi_sio in a previous patch. Tested on a CP2102N.

gnss: sirf: fix premature wakeup interrupt enable

2019-03-10T06:09:01+00:00

commit 82f844c22588bf47132c82faeda50b6db473162c upstream. Make sure the receiver is powered (and booted) before enabling the wakeup interrupt to avoid spurious interrupts due to a floating input. Similarly, disable the interrupt before powering off on probe errors and on unbind.

applicom: Fix potential Spectre v1 vulnerabilities

2019-03-10T06:09:00+00:00

commit d7ac3c6ef5d8ce14b6381d52eb7adafdd6c8bb3c upstream. IndexCard is indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: drivers/char/applicom.c:418 ac_write() warn: potential spectre issue 'apbs' [r] drivers/char/applicom.c:728 ac_ioctl() warn: potential spectre issue 'apbs' [r] (local cap) Fix this by sanitizing IndexCard before using it to index apbs. Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

team: Free BPF filter when unregistering netdev

2019-03-10T06:09:00+00:00

[ Upstream commit 692c31bd4054212312396b1d303bffab2c5b93a7 ] When team is used in loadbalance mode a BPF filter can be used to provide a hash which will determine the Tx port. When the netdev is later unregistered the filter is not freed which results in memory leaks [1]. Fix by freeing the program and the corresponding filter when unregistering the netdev.

The modem behaves in the same way as the EP06, so the "set DTR"-quirk must be applied and the diagnostic-interface check performed. Since the diagnostic-check now applies to more modems, I have renamed the function from quectel_ep06_diag_detected() to quectel_diag_detected().
