ANDROID: tty: fix tty name overflow
The tty name can be up to 8 chars if id is greater than 10 such as
ttyUSB11. In that case, the name will be overflowed. To prevent this,
this patch removes snprintf and adds comparison the idx value of
pdev_tty_port only if pdev_tty_port is specified.

vt: Reject zero-sized screen buffer size.
commit ce684552a266cb1c7cc2f7e623f38567adec6653 upstream. syzbot is reporting general protection fault in do_con_write() [1] caused by vc->vc_screenbuf == ZERO_SIZE_PTR caused by vc->vc_screenbuf_size == 0 caused by vc->vc_cols == vc->vc_rows == vc->vc_size_row == 0 caused by fb_set_var() from ioctl(FBIOPUT_VSCREENINFO) on /dev/fb0 , for gotoxy(vc, 0, 0) from reset_terminal() from vc_init() from vc_allocate() from con_install() from tty_init_dev() from tty_open() on such console causes vc->vc_pos == 0x10000000e due to ((unsigned long) ZERO_SIZE_PTR) + -1U * 0 + (-1U << 1). I don't think that a console with 0 column or 0 row makes sense. And it seems that vc_do_resize() does not intend to allow resizing a console to 0 column or 0 row due to new_cols = (cols ? cols : vc->vc_cols); new_rows = (lines ? lines : vc->vc_rows); exception. Theoretically, cols and rows can be any range as long as 0 < cols * rows * 2 <= KMALLOC_MAX_SIZE is satisfied (e.g. cols == 1048576 && rows == 2 is possible) because of vc->vc_size_row = vc->vc_cols << 1; vc->vc_screenbuf_size = vc->vc_rows * vc->vc_size_row; in visual_init() and kzalloc(vc->vc_screenbuf_size) in vc_allocate(). Since we can detect cols == 0 or rows == 0 via screenbuf_size = 0 in visual_init(), we can reject kzalloc(0). Then, vc_allocate() will return an error, and con_write() will not be called on a console with 0 column or 0 row. We need to make sure that integer overflow in visual_init() won't happen. Since vc_do_resize() restricts cols <= 32767 and rows <= 32767, applying 1 <= cols <= 32767 and 1 <= rows <= 32767 restrictions to vc_allocate() will be practically fine. This patch does not touch con_init(), for returning -EINVAL there does not help when we are not returning -ENOMEM.

serial: 8250_mtk: Fix high-speed baud rates clamping
commit 551e553f0d4ab623e2a6f424ab5834f9c7b5229c upstream.
Commit 7b668c064ec3 ("serial: 8250: Fix max baud limit in generic 8250
port") fixed limits of a baud rate setting for a generic 8250 port.
In other words since that commit the baud rate has been permitted to be
within [uartclk / 16 / UART_DIV_MAX; uartclk / 16], which is absolutely
normal for a standard 8250 UART port. But there are custom 8250 ports,
which provide extended baud rate limits. In particular the Mediatek 8250
port can work with baud rates up to "uartclk" speed.
Normally that and any other peculiarity is supposed to be handled in a
custom set_termios() callback implemented in the vendor-specific
8250-port glue-driver. Currently that is how it's done for the most of
the vendor-specific 8250 ports, but for some reason for Mediatek a
solution has been spread out to both the glue-driver and to the generic
8250-port code. Due to that a bug has been introduced, which permitted the
extended baud rate limit for all even for standard 8250-ports. The bug
has been fixed by the commit 7b668c064ec3 ("serial: 8250: Fix max baud
limit in generic 8250 port") by narrowing the baud rates limit back down to
the normal bounds. Unfortunately by doing so we also broke the
Mediatek-specific extended bauds feature.
A fix of the problem described above is twofold. First since we can't get
back the extended baud rate limits feature to the generic set_termios()
function and that method supports only a standard baud rates range, the
requested baud rate must be locally stored before calling it and then
restored back to the new termios structure after the generic set_termios()
finished its magic business. By doing so we still use the
serial8250_do_set_termios() method to set the LCR/MCR/FCR/etc. registers,
while the extended baud rate setting procedure will be performed later in
the custom Mediatek-specific set_termios() callback. Second since a true
baud rate is now fully calculated in the custom set_termios() method we
need to locally update the port timeout by calling the
uart_update_timeout() function. After the fixes described above are
implemented in the 8250_mtk.c driver, the Mediatek 8250-port should
get back to normally working with extended baud rates.

tty: xilinx_uartps: Really fix id assignment
commit 22a82fa7d6c3e16d56a036b1fa697a39b954adf0 upstream. The problems started with the revert (18cc7ac8a28e28). The cdns_uart_console.index is statically assigned -1. When the port is registered, Linux assigns consecutive numbers to it. It turned out that when using ttyPS1 as console, the index is not updated as we are reusing the same cdns_uart_console instance for multiple ports. When registering ttyPS0, it gets updated from -1 to 0, but when registering ttyPS1, it already is 0 and not updated. That led to 2ae11c46d5fdc4. It assigns the index prior to registering the uart_driver once. Unfortunately, that ended up breaking the situation where the probe order does not match the id order. When using the same device tree for both uboot and linux, it is important that the serial0 alias points to the console. So some boards reverse those aliases. This was reported by Jan Kiszka. The proposed fix was reverting the index assignment and going back to the previous iteration. However such a reversed assignement (serial0 -> uart1, serial1 -> uart0) was already partially broken by the revert (18cc7ac8a28e28). While the ttyPS device works, the kmsg connection is already broken and kernel messages go missing. Reverting the id assignment does not fix this. >From the xilinx_uartps driver pov (after reverting the refactoring commits), there can be only one console. This manifests in static variables console_pprt and cdns_uart_console. These variables are not properly linked and can go out of sync. The cdns_uart_console.index is important for uart_add_one_port. We call that function for each port - one of which hopefully is the console. If it isn't, the CON_ENABLED flag is not set and console_port is cleared. The next cdns_uart_probe call then tries to register the next port using that same cdns_uart_console. It is important that console_port and cdns_uart_console (and its index in particular) stay in sync. The index assignment implemented by Shubhrajyoti Datta is correct in principle. It just may have to happen a second time if the first cdns_uart_probe call didn't encounter the console device. And we shouldn't change the index once the console uart is registered.

serial: mxs-auart: add missed iounmap() in probe failure and remove
commit d8edf8eb5f6e921fe6389f96d2cd05862730a6ff upstream.
This driver calls ioremap() in probe, but it misses calling iounmap() in
probe's error handler and remove.
Add the missed calls to fix it.

Revert "tty: xilinx_uartps: Fix missing id assignment to the console"
commit 76ed2e105796710cf5b8a4ba43c81eceed948b70 upstream.
This reverts commit 2ae11c46d5fdc46cb396e35911c713d271056d35.
It turned out to break the ultra96-rev1, e.g., which uses uart1 as
serial0 (and stdout-path = "serial0:115200n8").

tty: n_gsm: Fix bogus i++ in gsm_data_kick
[ Upstream commit 4dd31f1ffec6c370c3c2e0c605628bf5e16d5c46 ]
When submitting the previous fix "tty: n_gsm: Fix waking up upper tty
layer when room available". It was suggested to switch from a while to
a for loop, but when doing it, there was a remaining bogus i++.
This patch removes this i++ and also reorganizes the code making it more
compact.

tty: n_gsm: Fix SOF skipping
[ Upstream commit 84d6f81c1fb58b56eba81ff0a36cf31946064b40 ]
For at least some modems like the TELIT LE910, skipping SOF makes
transfers blocking indefinitely after a short amount of data
transferred.
Given the small improvement provided by skipping the SOF (just one
byte on about 100 bytes), it seems better to completely remove this
"feature" than make it optional.

Its a little confusing, as uart_port_spin_lock_init() is one place where the lock is supposed to be initialized, but it has an exception for the case where the port is a console. This makes it seem like a deeper fix is needed to properly register the console, but I'm not sure what that entails, and Andy suggested that this approach is less invasive. Thus, this patch resolves the issue by initializing the spinlock in the driver, and resolves the resulting warning.

tty: hvc: Fix data abort due to race in hvc_open
[ Upstream commit e2bd1dcbe1aa34ff5570b3427c530e4332ecf0fe ] Potentially, hvc_open() can be called in parallel when two tasks calls open() on /dev/hvcX. In such a scenario, if the hp->ops->notifier_add() callback in the function fails, where it sets the tty->driver_data to NULL, the parallel hvc_open() can see this NULL and cause a memory abort. Hence, serialize hvc_open and check if tty->private_data is NULL before proceeding ahead. The issue can be easily reproduced by launching two tasks simultaneously that does nothing but open() and close() on /dev/hvcX. For example: $ ./simple_open_close /dev/hvc0 & ./simple_open_close /dev/hvc0 & Signed-off-by: Raghavendra Rao Ananta <rananta@codeaurora.org> Link: https://lore.kernel.org/r/20200428032601.22127-1-rananta@codeaurora.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sasha Levin <sashal@kernel.org> |

serial: 8250: Fix max baud limit in generic 8250 port
[ Upstream commit 7b668c064ec33f3d687c3a413d05e355172e6c92 ]
Standard 8250 UART ports are designed in a way so they can communicate
with baud rates up to 1/16 of a reference frequency. It's expected from
most of the currently supported UART controllers. That's why the former
version of serial8250_get_baud_rate() method called uart_get_baud_rate()
with min and max baud rates passed as (port->uartclk / 16 / UART_DIV_MAX)
and ((port->uartclk + tolerance) / 16) respectively. Doing otherwise, like
it was suggested in commit ("serial: 8250_mtk: support big baud rate."),
caused acceptance of bauds, which was higher than the normal UART
controllers actually supported. As a result if some user-space program
requested to set a baud greater than (uartclk / 16) it would have been
permitted without truncation, but then serial8250_get_divisor(baud)
(which calls uart_get_divisor() to get the reference clock divisor) would
have returned a zero divisor. Setting zero divisor will cause an
unpredictable effect varying from chip to chip. In case of DW APB UART the
communications just stop.
Lets fix this problem by getting back the limitation of (uartclk +
tolerance) / 16 maximum baud supported by the generic 8250 port. Mediatek
8250 UART ports driver developer shouldn't have touched it in the first
place notably seeing he already provided a custom version of set_termios()
callback in that glue-driver which took into account the extended baud
rate values and accordingly updated the standard and vendor-specific
divisor latch registers anyway.

commit e0a851fe6b9b619527bd928aa93caaddd003f70c upstream. If the call to uart_add_one_port() in serial8250_register_8250_port() fails, a half-initialized entry in the serial_8250ports[] array is left behind. A subsequent reprobe of the same serial port causes that entry to be reused. Because uart->port.dev is set, uart_remove_one_port() is called for the half-initialized entry and bails out with an error message: bcm2835-aux-uart 3f215040.serial: Removing wrong port: (null) != (ptrval) The same happens on failure of mctrl_gpio_init() since commit |

kgdboc: Use a platform device to handle tty drivers showing up late
[ Upstream commit 68e55f61c13842baf825958129698c5371db432c ] If you build CONFIG_KGDB_SERIAL_CONSOLE into the kernel then you should be able to have KGDB init itself at bootup by specifying the "kgdboc=..." kernel command line parameter. This has worked OK for me for many years, but on a new device I switched to it stopped working. The problem is that on this new device the serial driver gets its probe deferred. Now when kgdb initializes it can't find the tty driver and when it gives up it never tries again. We could try to find ways to move up the initialization of the serial driver and such a thing might be worthwhile, but it's nice to be robust against serial drivers that load late. We could move kgdb to init itself later but that penalizes our ability to debug early boot code on systems where the driver inits early. We could roll our own system of detecting when new tty drivers get loaded and then use that to figure out when kgdb can init, but that's ugly. Instead, let's jump on the -EPROBE_DEFER bandwagon. We'll create a singleton instance of a "kgdboc" platform device. If we can't find our tty device when the singleton "kgdboc" probes we'll return -EPROBE_DEFER which means that the system will call us back later to try again when the tty device might be there. We won't fully transition all of the kgdboc to a platform device because early kgdb initialization (via the "ekgdboc" kernel command line parameter) still runs before the platform device has been created. The kgdb platform device is merely used as a convenient way to hook into the system's normal probe deferral mechanisms. As part of this, we'll ever-so-slightly change how the "kgdboc=..." kernel command line parameter works. Previously if you booted up and kgdb couldn't find the tty driver then later reading '/sys/module/kgdboc/parameters/kgdboc' would return a blank string. Now kgdb will keep track of the string that came as part of the command line and give it back to you. It's expected that this should be an OK change.

tty: hvc_console, fix crashes on parallel open/close
commit 24eb2377f977fe06d84fca558f891f95bc28a449 upstream. hvc_open sets tty->driver_data to NULL when open fails at some point. Typically, the failure happens in hp->ops->notifier_add(). If there is a racing process which tries to open such mangled tty, which was not closed yet, the process will crash in hvc_open as tty->driver_data is NULL. All this happens because close wants to know whether open failed or not. But ->open should not NULL this and other tty fields for ->close to be happy. ->open should call tty_port_set_initialized(true) and close should check by tty_port_initialized() instead. So do this properly in this driver. So this patch removes these from ->open: * tty_port_tty_set(&hp->port, NULL). This happens on last close. * tty->driver_data = NULL. Dtto. * tty_port_put(&hp->port). This happens in shutdown and until now, this must have been causing a reference underflow, if I am not missing something.

An uninitialised spin lock for sifive serial console raises a bad
magic spin_lock error as reported and discussed here [1].
Initialising the spin lock resolves the issue.
The fix is tested on HiFive Unleashed A00 board with Linux 5.7-rc4
and OpenSBI v0.7

tty: xilinx_uartps: Fix missing id assignment to the console
[ Upstream commit 2ae11c46d5fdc46cb396e35911c713d271056d35 ]
When serial console has been assigned to ttyPS1 (which is serial1 alias)
console index is not updated property and pointing to index -1 (statically
initialized) which ends up in situation where nothing has been printed on
the port.
The commit 18cc7ac8a28e ("Revert "serial: uartps: Register own uart console
and driver structures"") didn't contain this line which was removed by
accident.

vt: fix unicode console freeing with a common interface
[ Upstream commit 57d38f26d81e4275748b69372f31df545dcd9b71 ] By directly using kfree() in different places we risk missing one if it is switched to using vfree(), especially if the corresponding vmalloc() is hidden away within a common abstraction. Oh wait, that's exactly what happened here. So let's fix this by creating a common abstraction for the free case as well.

serial: sh-sci: Make sure status register SCxSR is read in correct sequence
commit 3dc4db3662366306e54ddcbda4804acb1258e4ba upstream. For SCIF and HSCIF interfaces the SCxSR register holds the status of data that is to be read next from SCxRDR register, But where as for SCIFA and SCIFB interfaces SCxSR register holds status of data that is previously read from SCxRDR register. This patch makes sure the status register is read depending on the port types so that errors are caught accordingly.

vt: don't use kmalloc() for the unicode screen buffer
commit 9a98e7a80f95378c9ee0c644705e3b5aa54745f1 upstream. Even if the actual screen size is bounded in vc_do_resize(), the unicode buffer is still a little more than twice the size of the glyph buffer and may exceed MAX_ORDER down the kmalloc() path. This can be triggered from user space. Since there is no point having a physically contiguous buffer here, let's avoid the above issue as well as reducing pressure on high order allocations by using vmalloc() instead.

vt: don't hardcode the mem allocation upper bound
commit 2717769e204e83e65b8819c5e2ef3e5b6639b270 upstream.
The code in vc_do_resize() bounds the memory allocation size to avoid
exceeding MAX_ORDER down the kzalloc() call chain and generating a
runtime warning triggerable from user space. However, not only is it
unwise to use a literal value here, but MAX_ORDER may also be
configurable based on CONFIG_FORCE_MAX_ZONEORDER.
Let's use KMALLOC_MAX_SIZE instead.

tty: rocket, avoid OOB access
commit 7127d24372bf23675a36edc64d092dc7fd92ebe8 upstream.
init_r_port can access pc104 array out of bounds. pc104 is a 2D array
defined to have 4 members. Each member has 8 submembers.
* we can have more than 4 (PCI) boards, i.e. [board] can be OOB
* line is not modulo-ed by anything, so the first line on the second
board can be 4, on the 3rd 12 or alike (depending on previously
registered boards). It's zero only on the first line of the first
board. So even [line] can be OOB, quite soon (with the 2nd registered
board already).
This code is broken for ages, so just avoid the OOB accesses and don't
try to fix it as we would need to find out the correct line number. Use
the default: RS232, if we are out.
Generally, if anyone needs to set the interface types, a module parameter
is past the last thing that should be used for this purpose. The
parameters' description says it's for ISA cards anyway.
