[Linux-stable-mirror] [PATCH] serial: core: mark port as initialized in autoconfig

by Sebastian Andrzej Siewior

This is a followup on 44117a1d1732 ("serial: core: mark port as initialized after successful IRQ change"). Nikola has been using autoconfig via setserial and reported a crash similar to what I fixed in the earlier mentioned commit. Here I do the same fixup for the autoconfig. I wasn't sure that this is the right approach. Nikola confirmed that it fixes his crash. Fixes: b3b576461864 ("tty: serial_core: convert uart_open to use tty_port_open") Link: http://lkml.kernel.org/r/20180131072000.GD1853@localhost.localdomain Reported-by: Nikola Ciprich <nikola.ciprich(a)linuxbox.cz> Tested-by: Nikola Ciprich <nikola.ciprich(a)linuxbox.cz> Cc: Johan Hovold <johan(a)kernel.org> Cc: Nikola Ciprich <nikola.ciprich(a)linuxbox.cz> Cc: <stable(a)vger.kernel.org> Signed-off-by: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> --- drivers/tty/serial/serial_core.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/tty/serial/serial_core.c b/drivers/tty/serial/serial_core.c index c8dde56b532b..35b9201db3b4 100644 --- a/drivers/tty/serial/serial_core.c +++ b/drivers/tty/serial/serial_core.c @@ -1144,6 +1144,8 @@ static int uart_do_autoconfig(struct tty_struct *tty,struct uart_state *state) uport->ops->config_port(uport, flags); ret = uart_startup(tty, state, 1); + if (ret == 0) + tty_port_set_initialized(port, true); if (ret > 0) ret = 0; } -- 2.15.1

[Linux-stable-mirror] [PATCH AUTOSEL for 4.9 01/52] dmaengine: fsl-edma: disable clks on all error paths

by Sasha Levin

From: Andreas Platschek <andreas.platschek(a)opentech.at> [ Upstream commit 2610acf46b9ed528ec2cacd717bc9d354e452b73 ] Previously enabled clks are only disabled if clk_prepare_enable() fails. However, there are other error paths were the previously enabled clocks are not disabled. To fix the problem, fsl_disable_clocks() now takes the number of clocks that shall be disabled + unprepared. For existing calls were all clocks were already successfully prepared + enabled, DMAMUX_NR is passed to disable + unprepare all clocks. In error paths were only some clocks were successfully prepared + enabled the loop counter is passed, in order to disable + unprepare all successfully prepared + enabled clocks.

[Linux-stable-mirror] [PATCH AUTOSEL for 3.18 01/24] mtd: nand: gpmi: Fix failure when a erased page has a bitflip at BBM

by Sasha Levin

From: Sascha Hauer <s.hauer(a)pengutronix.de> [ Upstream commit fdf2e821052958a114618a95ab18a300d0b080cb ] When erased subpages are read then the BCH decoder returns STATUS_ERASED if they are all empty, or STATUS_UNCORRECTABLE if there are bitflips. When there are bitflips, we have to set these bits again to show the upper layers a completely erased page. When a bitflip happens in the exact byte where the bad block marker is, then this byte is swapped with another byte in block_mark_swapping(). The correction code then detects a bitflip in another subpage and no longer corrects the bitflip where it really happens. Correct this behaviour by calling block_mark_swapping() after the bitflips have been corrected.

[Linux-stable-mirror] [PATCH] serial: core: mark port as initialized after successful IRQ change

by Sebastian Andrzej Siewior

Upstream commit 44117a1d1732c513875d5a163f10d9adbe866c08 I wanted to wait initially to see if it breaks something so I omitted the stable tag. Johan suggested to speed up things here after user report against a v4.14 kernel. Fixes: b3b576461864 ("tty: serial_core: convert uart_open to use tty_port_open") setserial changes the IRQ via uart_set_info(). It invokes uart_shutdown() which free the current used IRQ and clear TTY_PORT_INITIALIZED. It will then update the IRQ number and invoke uart_startup() before returning to the caller leaving TTY_PORT_INITIALIZED cleared. The next open will crash with | list_add double add: new=ffffffff839fcc98, prev=ffffffff839fcc98, next=ffffffff839fcc98. since the close from the IOCTL won't free the IRQ (and clean the list) due to the TTY_PORT_INITIALIZED check in uart_shutdown(). There is same pattern in uart_do_autoconfig() and I *think* it also needs to set TTY_PORT_INITIALIZED there. Is there a reason why uart_startup() does not set the flag by itself after the IRQ has been acquired (since it is cleared in uart_shutdown)?
