Johan Hovold	c9ca201020	serdev: ttyport: restore client ops on deregistration commit `0c5aae5927` upstream. The serdev tty-port controller driver should reset the tty-port client operations also on deregistration to avoid a NULL-pointer dereference in case the port is later re-registered as a normal tty device. Note that this can only happen with tty drivers such as 8250 which have statically allocated port structures that can end up being reused and where a later registration would not register a serdev controller (e.g. due to registration errors or if the devicetree has been changed in between). Specifically, this can be an issue for any statically defined ports that would be registered by 8250 core when an 8250 driver is being unbound.

Andy Shevchenko	f4e6d51f3f	serial: 8250: Check UPF_IRQ_SHARED in advance commit `7febbcbc48` upstream. The commit `54e53b2e80` ("tty: serial: 8250: pass IRQ shared flag to UART ports") nicely explained the problem: ---8<---8<--- On some systems IRQ lines between multiple UARTs might be shared. If so, the irqflags have to be configured accordingly. The reason is: The 8250 port startup code performs IRQ tests before the IRQ handler for that particular port is registered. This is performed in serial8250_do_startup(). This function checks whether IRQF_SHARED is configured and only then disables the IRQ line while testing. This test is performed upon each open() of the UART device. Imagine two UARTs share the same IRQ line: On is already opened and the IRQ is active. When the second UART is opened, the IRQ line has to be disabled while performing IRQ tests. Otherwise an IRQ might handler might be invoked, but the IRQ itself cannot be handled, because the corresponding handler isn't registered, yet. That's because the 8250 code uses a chain-handler and invokes the corresponding port's IRQ handling routines himself. Unfortunately this IRQF_SHARED flag isn't configured for UARTs probed via device tree even if the IRQs are shared. This way, the actual and shared IRQ line isn't disabled while performing tests and the kernel correctly detects a spurious IRQ. So, adding this flag to the DT probe solves the issue. Note: The UPF_SHARE_IRQ flag is configured unconditionally. Therefore, the IRQF_SHARED flag can be set unconditionally as well. Example stack trace by performing `echo 1 > /dev/ttyS2` on a non-patched system: \|irq 85: nobody cared (try booting with the "irqpoll" option) \| [...] \|handlers: \|[<ffff0000080fc628>] irq_default_primary_handler threaded [<ffff00000855fbb8>] serial8250_interrupt \|Disabling IRQ #85 ---8<---8<--- But unfortunately didn't fix the root cause. Let's try again here by moving IRQ flag assignment from serial_link_irq_chain() to serial8250_do_startup(). This should fix the similar issue reported for 8250_pnp case. Since this change we don't need to have custom solutions in 8250_aspeed_vuart and 8250_of drivers, thus, drop them.

Jiri Slaby	abbf24fc5a	vt: selection, handle pending signals in paste_selection commit `687bff0cd0` upstream. When pasting a selection to a vt, the task is set as INTERRUPTIBLE while waiting for a tty to unthrottle. But signals are not handled at all. Normally, this is not a problem as tty_ldisc_receive_buf receives all the goods and a user has no reason to interrupt the task. There are two scenarios where this matters: 1) when the tty is throttled and a signal is sent to the process, it spins on a CPU until the tty is unthrottled. schedule() does not really echedule, but returns immediately, of course. 2) when the sel_buffer becomes invalid, KASAN prevents any reads from it and the loop simply does not proceed and spins forever (causing the tty to throttle, but the code never sleeps, the same as above). This sometimes happens as there is a race in the sel_buffer handling code. So add signal handling to this ioctl (TIOCL_PASTESEL) and return -EINTR in case a signal is pending.

Nicolas Pitre	d4878c57a1	vt: fix scrollback flushing on background consoles commit `3f4ef485be` upstream. Commit `a6dbe44275` ("vt: perform safe console erase in the right order") provided fixes to an earlier commit by gathering all console scrollback flushing operations in a function of its own. This includes the invocation of vc_sw->con_switch() as previously done through a update_screen() call. That commit failed to carry over the con_is_visible() conditional though, as well as cursor handling, which caused problems when "\e[3J" was written to a background console. One could argue for preserving the call to update_screen(). However this does far more than we need, and it is best to remove scrollback assumptions from it. Instead let's gather the minimum needed to actually perform scrollback flushing properly in that one place. While at it, let's document the vc_sw->con_switch() side effect being relied upon.

Lukas Wunner	ad7a72e818	serial: 8250_bcm2835aux: Fix line mismatch on driver unbind commit `dc76697d7e` upstream. Unbinding the bcm2835aux UART driver raises the following error if the maximum number of 8250 UARTs is set to 1 (via the 8250.nr_uarts module parameter or CONFIG_SERIAL_8250_RUNTIME_UARTS): (NULL device *): Removing wrong port: a6f80333 != fa20408b That's because bcm2835aux_serial_probe() retrieves UART line number 1 from the devicetree and stores it in data->uart.port.line, while serial8250_register_8250_port() instead uses UART line number 0, which is stored in data->line. On driver unbind, bcm2835aux_serial_remove() uses data->uart.port.line, which contains the wrong number. Fix it. The issue does not occur if the maximum number of 8250 UARTs is >= 2.

Per Documentation/DMA-API-HOWTO.txt, To unmap a scatterlist, just call: dma_unmap_sg(dev, sglist, nents, direction); .. note:: The 'nents' argument to the dma_unmap_sg call must be the _same_ one you passed into the dma_map_sg call, it should _NOT_ be the 'count' value _returned_ from the dma_map_sg call. However in the driver, priv->nent is directly assigned with value returned from dma_map_sg, and dma_unmap_sg use priv->nent for unmap, this breaks the API usage.

Sudip Mukherjee	1656f00bec	tty: always relink the port commit `273f632912` upstream. If the serial device is disconnected and reconnected, it re-enumerates properly but does not link it. fwiw, linking means just saving the port index, so allow it always as there is no harm in saving the same value again even if it tries to relink with the same port.

Sudip Mukherjee	65c6710c3f	tty: link tty and port before configuring it as console commit `fb2b90014d` upstream. There seems to be a race condition in tty drivers and I could see on many boot cycles a NULL pointer dereference as tty_init_dev() tries to do 'tty->port->itty = tty' even though tty->port is NULL. 'tty->port' will be set by the driver and if the driver has not yet done it before we open the tty device we can get to this situation. By adding some extra debug prints, I noticed that: 6.650130: uart_add_one_port 6.663849: register_console 6.664846: tty_open 6.674391: tty_init_dev 6.675456: tty_port_link_device uart_add_one_port() registers the console, as soon as it registers, the userspace tries to use it and that leads to tty_open() but uart_add_one_port() has not yet done tty_port_link_device() and so tty->port is not yet configured when control reaches tty_init_dev(). Further look into the code and tty_port_link_device() is done by uart_add_one_port(). After registering the console uart_add_one_port() will call tty_port_register_device_attr_serdev() and tty_port_link_device() is called from this. Call add tty_port_link_device() before uart_configure_port() is done and add a check in tty_port_link_device() so that it only links the port if it has not been done yet.

Punit Agrawal	8b16b0cb36	serdev: Don't claim unsupported ACPI serial devices commit `c5ee0b3104` upstream. Serdev sub-system claims all ACPI serial devices that are not already initialised. As a result, no device node is created for serial ports on certain boards such as the Apollo Lake based UP2. This has the unintended consequence of not being able to raise the login prompt via serial connection. Introduce a blacklist to reject ACPI serial devices that should not be claimed by serdev sub-system. Add the peripheral ids for Intel HS UART to the blacklist to bring back serial port on SoCs carrying them.

John Stultz	2fdad105a0	ANDROID: tty: serdev: Fix broken serial console input Since commit `c550a54f23` ("ANDROID: serdev: add platform device support"), the serial console on the db845c has stopped taking input. Digging in it seems when the tty used for the console is switched to serdev via serdev_tty_port_register(), the client_ops are changed here: https://android.googlesource.com/kernel/common/+/android-mainline/drivers/tty/serdev/serdev-ttyport.c#288 The problem being, the new client_ops->receive_buf function ttyport_receive_buf() starts failing on the SERPORT_ACTIVE test here: https://android.googlesource.com/kernel/common/+/android-mainline/drivers/tty/serdev/serdev-ttyport.c#32 Which seems to be due to the fact that the tty was already opened and being used as the console when it was switched to serdev. Thus ctrl_ops->open function never gets called, which prevents the SERPORT_ACTIVE bit from being set: https://android.googlesource.com/kernel/common/+/android-mainline/drivers/tty/serdev/serdev-ttyport.c#141 Now this was at first confusing as on the HiKey960 we don't see the issue. But in the HiKey960 case it seem the check here: https://android.googlesource.com/kernel/common/+/android-mainline/drivers/tty/serdev/core.c#737 fails preventing the tty from being switched to serdev. Thus this patch tries to avoid switching the tty to serdev if the tty port's console value is true. With this, the serial console continues to function.

Daniel Axtens	3d14b83e71	powerpc/pseries/hvconsole: Fix stack overread via udbg [ Upstream commit `934bda59f2` ] While developing KASAN for 64-bit book3s, I hit the following stack over-read. It occurs because the hypercall to put characters onto the terminal takes 2 longs (128 bits/16 bytes) of characters at a time, and so hvc_put_chars() would unconditionally copy 16 bytes from the argument buffer, regardless of supplied length. However, udbg_hvc_putc() can call hvc_put_chars() with a single-byte buffer, leading to the error. ================================================================== BUG: KASAN: stack-out-of-bounds in hvc_put_chars+0xdc/0x110 Read of size 8 at addr c0000000023e7a90 by task swapper/0 CPU: 0 PID: 0 Comm: swapper Not tainted 5.2.0-rc2-next-20190528-02824-g048a6ab4835b #113 Call Trace: dump_stack+0x104/0x154 (unreliable) print_address_description+0xa0/0x30c __kasan_report+0x20c/0x224 kasan_report+0x18/0x30 __asan_report_load8_noabort+0x24/0x40 hvc_put_chars+0xdc/0x110 hvterm_raw_put_chars+0x9c/0x110 udbg_hvc_putc+0x154/0x200 udbg_write+0xf0/0x240 console_unlock+0x868/0xd30 register_console+0x970/0xe90 register_early_udbg_console+0xf8/0x114 setup_arch+0x108/0x790 start_kernel+0x104/0x784 start_here_common+0x1c/0x534 Memory state around the buggy address: c0000000023e7980: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 c0000000023e7a00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 f1 f1 >c0000000023e7a80: f1 f1 01 f2 f2 f2 00 00 00 00 00 00 00 00 00 00 ^ c0000000023e7b00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 c0000000023e7b80: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ================================================================== Document that a 16-byte buffer is requred, and provide it in udbg.

Leo Yan	2db81976ca	tty: serial: msm_serial: Fix lockup for sysrq and oops commit `0e4f7f920a` upstream. As the commit `677fe555cb` ("serial: imx: Fix recursive locking bug") has mentioned the uart driver might cause recursive locking between normal printing and the kernel debugging facilities (e.g. sysrq and oops). In the commit it gave out suggestion for fixing recursive locking issue: "The solution is to avoid locking in the sysrq case and trylock in the oops_in_progress case." This patch follows the suggestion (also used the exactly same code with other serial drivers, e.g. amba-pl011.c) to fix the recursive locking issue, this can avoid stuck caused by deadlock and print out log for sysrq and oops.

David Engraf	3184e03c4b	tty/serial: atmel: fix out of range clock divider handling [ Upstream commit `cb47b9f863` ] Use MCK_DIV8 when the clock divider is > 65535. Unfortunately the mode register was already written thus the clock selection is ignored. Fix by doing the baud rate calulation before setting the mode.

John Stultz	3fff726cd6	ANDROID: serdev: Fix platform device support After commit `3c996ff885` ("ANDROID: serdev: add platform device support") landed, we started seeing boot panics on HiKey960/HiKey. After some debugging I found the patch is passing a serdev_device->dev pointer to match(), which expects the dev pointer to be contained in a platform_device structure instead. When it uses container_of, it ends up miscast and we get bad values. Alistair suggested this fix which seems to avoid the issue.

Alistair Delva	3c996ff885	ANDROID: serdev: add platform device support Enables devices on a platform bus, such as serial8250 on the ISA bus, to be enumerated by the serdev subsystem. This enables further layering by e.g. the gnss subsystem. With this in change, these devices can now register with the serdev core and show up as serdev tty ports (serialX) and child devices (serialX-Y). serial8250: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a U6_16550A serial serial0: tty port ttyS0 registered serial8250: ttyS1 at I/O 0x2f8 (irq = 3, base_baud = 115200) is a U6_16550A serial serial1: tty port ttyS1 registered serial8250: ttyS2 at I/O 0x3e8 (irq = 4, base_baud = 115200) is a U6_16550A serial serial2: tty port ttyS2 registered serial8250: ttyS3 at I/O 0x2e8 (irq = 3, base_baud = 115200) is a U6_16550A serial serial3: tty port ttyS3 registered The modalias shows up like this: # cat /sys/bus/serial/devices/serial0-0/modalias platform:serial8250 Bug: 146517987 Change-Id: I3711c9d9ecd66fad638a45a8745e97569ae01791 Signed-off-by: Alistair Delva <adelva@google.com>	2019-12-19 22:51:43 +00:00
Nicolas Pitre	627f3b9e4d	vcs: prevent write access to vcsu devices commit `0c9acb1af7` upstream. Commit `d21b0be246` ("vt: introduce unicode mode for /dev/vcs") guarded against using devices containing attributes as this is not yet implemented. It however failed to guard against writes to any devices as this is also unimplemented.
