Usage is as follows: myled=ledname tty=ttyS0 echo tty > /sys/class/leds/$myled/trigger echo $tty > /sys/class/leds/$myled/ttyname . When this new trigger is active it periodically checks the tty's statistics and when it changed since the last check the led is flashed once.

vcc_get() returns the port that has provided port->index. As the port that is about to be removed isn't removed yet this trivially will find this port. So simplify the call to not assign an identical value to the port pointer and drop the warning that is never hit.

If vcc_probe() succeeded dev_set_drvdata() is called with a non-NULL value, and if vcc_probe() failed vcc_remove() isn't called. So there is no way dev_get_drvdata() can return NULL in vcc_remove() and the check can just go away.

n_tty_flush_buffer can happen in parallel with n_tty_close that the tty->disc_data will be set to NULL. n_tty_flush_buffer accesses tty->disc_data, so we must prevent n_tty_close clear tty->disc_data while n_tty_flush_buffer has a non-NULL view of tty->disc_data. So we need to make sure that accesses to disc_data are atomic using tty->termios_rwsem. There is an example I meet: When n_tty_flush_buffer accesses tty struct, the disc_data is right. However, then reset_buffer_flags accesses tty->disc_data, disc_data become NULL, So kernel crash when accesses tty->disc_data->real_tail. I guess there could be another thread change tty->disc_data to NULL, and during N_TTY line discipline, n_tty_close will set tty->disc_data to be NULL. So use tty->termios_rwsem to protect disc_data between close and flush_buffer.

Remove the tty_vhangup() from the pty code and just release the redirect. The tty_vhangup() results in data loss and data out of order issues. If you write to a pty master an immediately close the pty master, the receiver might get a chunk of data dropped, but then receive some later data. That's obviously something rather unexpected for a user. It certainly confused my test program. It turns out that tty_vhangup() on the slave pty gets called from pty_close(), and that causes the data on the slave side to be flushed, but due to races more data can be copied into the slave side's buffer after that. Consider the following sequence: thread1 thread2 thread3 ------- ------- ------- | |-write data into buffer, | | n_tty buffer is filled | | along with other buffers | |-pty_close(master) | |--tty_vhangup(slave) | |---tty_ldisc_hangup() | |----n_tty_flush_buffer() | |-----reset_buffer_flags() |-n_tty_read() | |--up_read(&tty->termios_rwsem); | |------down_read(&tty->termios_rwsem) | |------clear n_tty buffer contents | |------up_read(&tty->termios_rwsem) |--tty_buffer_flush_work() | |--schedules work calling | | flush_to_ldisc() | | |-flush_to_ldisc() | |--receive_buf() | |---tty_port_default_receive_buf() | |----tty_ldisc_receive_buf() | |-----n_tty_receive_buf2() | |------n_tty_receive_buf_common() | |-------down_read(&tty->termios_rwsem) | |-------__receive_buf() | | copies data into n_tty buffer | |-------up_read(&tty->termios_rwsem) |--down_read(&tty->termios_rwsem) |--copy buffer data to user >From this sequence, you can see that thread2 writes to the buffer then only clears the part of the buffer in n_tty. The n_tty receive buffer code then copies more data into the n_tty buffer. But part of the vhangup, releasing the redirect, is still required to avoid issues with consoles running on pty slaves. So do that. As far as I can tell, that is all that should be required.

The transmission complete error message provides the status of the ISR_USART_TC bit. This bit, when set, indicates that the transmission has not been completed. The bit status indication is not a very understandable information. The error message sent on console should indicate that the transmission is not complete, instead of providing USART_TC bit status. Update the error message and add a comment for better understanding.

The main purpose of tty_port::low_latency was removed in commit a9c3f68f (tty: Fix low_latency BUG) back in 2014. It was left in place for drivers as an optional tune knob.

BROKEN_GRAPHICS_PROGRAMS is defined when CONFIG_VGA_CONSOLE=y. And vgacon.c is built exclusively in that case too. So the check for BROKEN_GRAPHICS_PROGRAMS is pointless in vgacon.c as it is always true. So remove the test and BROKEN_GRAPHICS_PROGRAMS completely. This also eliminates the need for vga_font_is_default global as it is only set and never read.

Drop support for these ioctls: * PIO_FONT, PIO_FONTX * GIO_FONT, GIO_FONTX * PIO_FONTRESET As was demonstrated by commit 90bfdeef (tty: make FONTX ioctl use the tty pointer they were actually passed), these ioctls are not used from userspace, as: 1) they used to be broken (set up font on current console, not the open one) and racy (before the commit above) 2) KDFONTOP ioctl is used for years instead Note that PIO_FONTRESET is defunct on most systems as VGA_CONSOLE is set on them for ages. That turns on BROKEN_GRAPHICS_PROGRAMS which makes PIO_FONTRESET just return an error. We are removing KD_FONT_FLAG_OLD here as it was used only by these removed ioctls. kd.h header exists both in kernel and uapi headers, so we can remove the kernel one completely. Everyone includeing kd.h will now automatically get the uapi one. There are now unused definitions of the ioctl numbers and "struct consolefontdesc" in kd.h, but as it is a uapi header, I am not touching these.

Introduce a new function tty_kopen_shared() that yields a struct tty_struct. The semantic difference to tty_kopen() is that the tty is expected to be used already. So rename tty_kopen() to tty_kopen_exclusive() for clearness, adapt the single user and put the common code in a new static helper function. tty_kopen_shared is to be used to implement an LED trigger for tty devices in one of the next patches.

Since commit 36e2c742 ("fs: don't allow splice read/write without explicit ops") we've required that file operation structures explicitly enable splice support, rather than falling back to the default handlers. Most /proc files use the indirect 'struct proc_ops' to describe their file operations, and were fixed up to support splice earlier in commits 40be821d..b24c30c6, but the mountinfo files interact with the VFS directly using their own 'struct file_operations' and got missed as a result. This adds the necessary support for splice to work for /proc/*/mountinfo and friends.
