[GIT PATCH] TTY/serial fixes for .37-rc1

[GIT PATCH] TTY/serial fixes for .37-rc1

[Greg KH]

Here are a number of tty and serial fixes for your .37-rc1 tree.

Full details are below, but there's just a range of bug fixes all over
the place, some of them having lived in the tree for quite some time,
and it's nice to get them finally resolved.

Please pull from:
	master.kernel.org:/pub/scm/linux/kernel/git/gregkh/tty-2.6.git/ tty-linus

Patches will be sent to the linux-kernel mailing list, if anyone wants
to see them.

thanks,

greg k-h

The function is a callback meant to be assigned to get_icount (added during 0587102cf).

[PATCH 06/19] tty: prevent DOS in the flush_to_ldisc

[Greg Kroah-Hartman]

From: Jiri Olsa <jolsa@redhat.com>

There's a small window inside the flush_to_ldisc function,
where the tty is unlocked and calling ldisc's receive_buf
function. If in this window new buffer is added to the tty,
the processing might never leave the flush_to_ldisc function.

This scenario will hog the cpu, causing other tty processing
starving, and making it impossible to interface the computer
via tty.

I was able to exploit this via pty interface by sending only
control characters to the master input, causing the flush_to_ldisc
to be scheduled, but never actually generate any output.

To reproduce, please run multiple instances of following code.

- SNIP
#define _XOPEN_SOURCE
#include <stdlib.h>
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

int main(int argc, char **argv)
{
        int i, slave, master = getpt();
        char buf[8192];

        sprintf(buf, "%s", ptsname(master));
        grantpt(master);
        unlockpt(master);

        slave = open(buf, O_RDWR);
        if (slave < 0) {
                perror("open slave failed");
                return 1;
        }

        for(i = 0; i < sizeof(buf); i++)
                buf[i] = rand() % 32;

        while(1) {
                write(master, buf, sizeof(buf));
        }

        return 0;
}
- SNIP

The attached patch (based on -next tree) fixes this by checking on the
tty buffer tail. Once it's reached, the current work is rescheduled
and another could run.

A kernel BUG when bluetooth rfcomm connection drop while the associated
serial port is open is sometime triggered.

It seems that the line discipline can disappear between the
tty_ldisc_put and tty_ldisc_get. This patch fall back to the N_TTY line
discipline if the previous discipline is not available anymore.

[PATCH 11/19] 8250: Fix tcsetattr to avoid ioctl(TIOCMIWAIT) hang

[Greg Kroah-Hartman]

From: Lawrence Rust <lvr@softsystem.co.uk>

Calling tcsetattr prevents any thread(s) currently suspended in ioctl
TIOCMIWAIT for the same device from ever resuming.

If a thread is suspended inside a call to ioctl TIOCMIWAIT, waiting for
a modem status change, then the 8250 driver enables modem status
interrupts (MSI).  The device interrupt service routine resumes the
suspended thread(s) on the next MSI.

If while the thread(s) are suspended, another thread calls tcsetattr
then the 8250 driver disables MSI (unless CTS/RTS handshaking is
enabled) thus preventing the suspended thread(s) from ever being
resumed.

This patch only disables MSI in tcsetattr handling if there are no
suspended threads.

[PATCH 12/19] amiserial: Remove unused variable icount

[Greg Kroah-Hartman]

From: Geert Uytterhoeven <geert@linux-m68k.org>

drivers/char/amiserial.c: In function ?rs_ioctl?:
drivers/char/amiserial.c:1302: warning: unused variable ?icount?

commit 0587102cf9f427c185bfdeb2cef41e13ee0264b1 ("tty: icount changeover for
other main devices") removed the users, but not the actual variable.

[PATCH 13/19] vcs: make proper usage of the poll flags

[Greg Kroah-Hartman]

From: Nicolas Pitre <nicolas.pitre@canonical.com>

Kay Sievers pointed out that usage of POLLIN is well defined by POSIX,
and the current usage here doesn't follow that definition.  So let's
duplicate the same semantics as implemented by sysfs_poll() instead.

[PATCH 14/19] serial: bfin_5xx: always include DMA headers

[Greg Kroah-Hartman]

From: Sonic Zhang <sonic.zhang@analog.com>

On Blackfin systems, peripherals that have optional DMA support always
route their interrupts through the corresponding DMA channel -- even
when DMA is not being used.  So in PIO mode, we still need to request
the DMA channel (so interrupts are delivered) which means we need to
always include the DMA header for the DMA defines/functions.

[PATCH 15/19] serial: bfin_5xx: remove redundant SSYNC to improve TX speed

[Greg Kroah-Hartman]

From: Sonic Zhang <sonic.zhang@analog.com>

We don't need to force a SSYNC here as the LSR register will already
be updated by the time we get back to reading it.  This speeds up TX
throughput and lowers general system overhead (since SSYNC is system
wide, not peripheral-specific).

Rebooting in 1 seconds..Press any key to enter the menu

It crashed almost immediately after i merged Linus's 9457b24a0955 into -tip, we were 
on yesterday's f6614b7bb405 before that - so i think the crash is both pretty 
generic.

Thanks,

Yes, it crashes with an x86 defconfig too. Appears to be caused by:

 47d3904fe40d: 8250: Fix tcsetattr to avoid ioctl(TIOCMIWAIT) hang

It crashes any x86 serial console bootup.

Thanks,

The revert below makes the system boot up fine.

Peering into the waitqueues like that isn't going to work.

I'd suggest simply keeping a proper count (locked) of the number of
people sitting in TIOCMIWAIT, and probably do it in serial_core (because
the bug doesn't look 8250 specific)

Maybe best to pull the patch for now and have a re-think.  Shame, it
seemed so easy and the fix works for me with a simple modem input.  I'll
re-submit later..
