[RESEND PATCH v4 1/7] serial: Do not hold the port lock when setting rx-during-tx GPIO

by Lino Sanfilippo

Both the imx and stm32 driver set the rx-during-tx GPIO in rs485_config(). Since this function is called with the port lock held, this can be an problem in case that setting the GPIO line can sleep (e.g. if a GPIO expander is used which is connected via SPI or I2C). Avoid this issue by moving the GPIO setting outside of the port lock into the serial core and thus making it a generic feature. Since both setting the term and the rx-during-tx GPIO is done at the same code place, move it into a common function. Fixes: c54d48543689 ("serial: stm32: Add support for rs485 RX_DURING_TX output GPIO") Fixes: ca530cfa968c ("serial: imx: Add support for RS485 RX_DURING_TX output GPIO") Cc: Shawn Guo <shawnguo(a)kernel.org> Cc: Sascha Hauer <s.hauer(a)pengutronix.de> Cc: stable(a)vger.kernel.org Signed-off-by: Lino Sanfilippo <l.sanfilippo(a)kunbus.com> --- drivers/tty/serial/imx.c | 4 ---- drivers/tty/serial/serial_core.c | 15 +++++++++++---- drivers/tty/serial/stm32-usart.c | 5 +---- 3 files changed, 12 insertions(+), 12 deletions(-) diff --git a/drivers/tty/serial/imx.c b/drivers/tty/serial/imx.c index 708b9852a575..9cffeb23112b 100644 --- a/drivers/tty/serial/imx.c +++ b/drivers/tty/serial/imx.c @@ -1943,10 +1943,6 @@ static int imx_uart_rs485_config(struct uart_port *port, struct ktermios *termio rs485conf->flags & SER_RS485_RX_DURING_TX) imx_uart_start_rx(port); - if (port->rs485_rx_during_tx_gpio) - gpiod_set_value_cansleep(port->rs485_rx_during_tx_gpio, - !!(rs485conf->flags & SER_RS485_RX_DURING_TX)); - return 0; } diff --git a/drivers/tty/serial/serial_core.c b/drivers/tty/serial/serial_core.c index f1348a509552..ab766f48c172 100644 --- a/drivers/tty/serial/serial_core.c +++ b/drivers/tty/serial/serial_core.c @@ -1392,14 +1392,21 @@ static void uart_sanitize_serial_rs485(struct uart_port *port, struct serial_rs4 memset(rs485->padding1, 0, sizeof(rs485->padding1)); } -static void uart_set_rs485_termination(struct uart_port *port, - const struct serial_rs485 *rs485) +/* + * Set optional RS485 GPIOs for bus termination and data reception during + * transmission.

[git:media_stage/master] media: mtk-jpeg: Fix timeout schedule error in mtk_jpegdec_worker.

Author: Zheng Wang <zyytlz.wz(a)163.com> Date: Mon Nov 6 15:48:11 2023 +0100 In mtk_jpegdec_worker, if error occurs in mtk_jpeg_set_dec_dst, it will start the timeout worker and invoke v4l2_m2m_job_finish at the same time. This will break the logic of design for there should be only one function to call v4l2_m2m_job_finish. But now the timeout handler and mtk_jpegdec_worker will both invoke it. Fix it by start the worker only if mtk_jpeg_set_dec_dst successfully finished.

[git:media_stage/master] media: mtk-jpeg: Fix use after free bug due to error path handling in mtk_jpeg_dec_device_run

by Mauro Carvalho Chehab

This is an automatic generated email to let you know that the following patch were queued: Subject: media: mtk-jpeg: Fix use after free bug due to error path handling in mtk_jpeg_dec_device_run Author: Zheng Wang <zyytlz.wz(a)163.com> Date: Mon Nov 6 15:48:10 2023 +0100 In mtk_jpeg_probe, &jpeg->job_timeout_work is bound with mtk_jpeg_job_timeout_work. In mtk_jpeg_dec_device_run, if error happens in mtk_jpeg_set_dec_dst, it will finally start the worker while mark the job as finished by invoking v4l2_m2m_job_finish. There are two methods to trigger the bug. If we remove the module, it which will call mtk_jpeg_remove to make cleanup. The possible sequence is as follows, which will cause a use-after-free bug.
