[ Upstream commit 1bb0c66332babc5cbc4581d962da0b03af9f23e8 ] 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.

tty: convert tty_ldisc_ops 'read()' function to take a kernel pointer

2021-03-04T11:14:00+00:00

[ Upstream commit 3b830a9c34d5897be07176ce4e6f2d75e2c8cfd7 ] The tty line discipline .read() function was passed the final user pointer destination as an argument, which doesn't match the 'write()' function, and makes it very inconvenient to do a splice method for ttys. This is a conversion to use a kernel buffer instead. NOTE! It does this by passing the tty line discipline ->read() function an additional "cookie" to fill in, and an offset into the cookie data. The line discipline can fill in the cookie data with its own private information, and then the reader will repeat the read until either the cookie is cleared or it runs out of data. The only real user of this is N_HDLC, which can use this to handle big packets, even if the kernel buffer is smaller than the whole packet.

Bluetooth: hci_qca: Wait for SSR completion during suspend

[ Upstream commit ad3a9c0ec2d2baed936cfdd05870f9d1e1f40e0e ] During SSR after memory dump collection,BT controller will be powered off, powered on and then FW will be downloaded.During suspend if BT controller is powered off due to SSR then we should wait until SSR is completed and then suspend.

Bluetooth: btusb: Fix memory leak in btusb_mtk_wmt_recv

2021-03-04T11:13:46+00:00

[ Upstream commit de71a6cb4bf24d8993b9ca90d1ddb131b60251a1 ] In btusb_mtk_wmt_recv if skb_clone fails, the alocated skb should be released. Omit the labels “err_out” and “err_free_skb” in this function implementation so that the desired exception handling code would be directly specified in the affected if branches.

Bluetooth: hci_uart: Fix a race for write_work scheduling

2021-03-04T11:13:36+00:00

[ Upstream commit afe0b1c86458f121b085271e4f3034017a90d4a3 ] 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.
