WARN/stack dump/oops in the bluetooth rfcomm code introduced in raw kernel 3.8.x
This is an *UPSTREAM* bug and also some collation of known information
of the nature of this bug.
A bug that was introduced upstream by the bluetooth developers in 3.8.x
which remains in 3.9.x will cause the machine to crash with an oops when
rfcomm is disconnected while a tty is connected. This is unexpected
behavior. While in 3.10-rc5 the behavior changed, the bug still exists.
The initial method to trigger this bug was listed in
http://forums.gentoo.org/viewtopic-t-961421-highlight-.html
In brief, set up any bluetooth rfcomm connection and then rip up the
bluetooth connection (/etc/init.d/bluetooth stop, rfcomm release, use
blueman to disconnect Dial Up Networking/Serial). (I believe that
pulling the bluetooth USB device from the plug also will trigger this
issue, but I'd call that nonnatural behavior.) The kernel will then
stomp over another kernel structure and cause the kernel to get
corrupted, making other subsystem oops.
As Gentoo appears to not have bluetooth setup for networkmanager, it
should not be affected unless someone is using rfcomm directly to
communicate with a bluetooth serial device, say over minicom for a
bluetooth device or using pppd directly to access a bluetooth modem. I
hit the bug because I have a /etc/portage/patches/net-
misc/networkmanager patch file to allow bluetooth rfcomm links.
As far as I can tell and from reports/tests upstream, this is probably
due to bluetooth rfcomm not following standard tty procedures ripping up
connected applications if the bluetooth link is torn down without
cleaning up the tty. A patch to expose the bad rfcomm behavior was
posted on LKML on 2013 May 15, which also prevents the machine from
hanging/crashing by stopping the memory corruption. It does not fix the
problem, merely instruments it (and also prevents other subsystems from
dying, causing potential data loss).
The patch that Peter Hurley wrote was:
diff --git a/drivers/tty/tty_port.c b/drivers/tty/tty_port.c
index 6d9e0b2..a4f4fa9 100644
--- a/drivers/tty/tty_port.c
+++ b/drivers/tty/tty_port.c
@@ -140,6 +140,10 @@ EXPORT_SYMBOL(tty_port_destroy);
static void tty_port_destructor(struct kref *kref)
{
struct tty_port *port = container_of(kref, struct tty_port, kref);

+ if (WARN_ON(port->itty))
+ return;
if (port->xmit_buf)
free_page((unsigned long)port->xmit_buf);
tty_port_destroy(port);
Attached is the warnings and errors generated when I disable rfcomm from blueman with the above patch showing the correct trace. Without the above patch, corruption will tend to make other functions show incorrect information and tends to completely crash/hang the machine shortly after disconnection.

There seems to have been a flame war on this on LKML on what to do when
the illegal situation arises. Alex's original patch was to BUG() when
the problem occurs, got rejected, but Peter suggested to WARN() on the
issue. Either should be fine to notify in syslog/console trace when the
improper procedure to tear down the tty occurs.
Either way, it's still just instrumenting the bug. There still appears
to be no true fixes are in sight. On June 25 LKML there was a message
reply to the subject "BUG: tty: memory corruption through
tty_release/tty_ldisc_release" that indicates the bug can also be
triggered by having the link open and suspend/resume the machine (ouch).
I suppose it's just because not many people use BT else this would be a
fairly serious bug...

Saw a message come by on linux-bluetooth/linux-serial mail lists, dated
Jul 6 2013 from Gianluka Anzolin who submitted a patch versus 3.10 which
may fix this issue, but the same doubts exist - people aren't sure how
this piece of software really works :(
Though it was suggested that it stopped the crash from happening.

Title:
Kernel Panic in 3.8.0, 3.8.1 & 3.8.2 when diconnecting from network
manager, using ppp0 to connect to net
Status in “linux” package in Ubuntu:
Confirmed
Status in “linux” package in Arch Linux:
New
Status in Gentoo Linux:
New
Bug description:
Using: "Ubuntu 12.04 (precise) 32-bit"
Machine: Laptop / old Toshiba / Celeron processor
Installing Kernel from: "http://kernel.ubuntu.com/~kernel-ppa/mainline/";
Apport disabled and uninstalled, so can't provide debug/log details
(this to make the machine run a bit faster, have been doing so since
10.04)
Have no problem with Kernel upto 3.7.10 (have been upgrading to Kernel 3.5/3.6/3.7/3.8, when ever new builds are available)
But when using Kernel 3.8.0/3.8.1/3.8.2, get Kernel Panic & machine crashes & freezes, have to hard boot.
PROBLEM #############################################
Machine connects to net using "ppp0" (modem on phone), then if you disconnect the modem "ppp0" & try to reconnect, the Kernel Panics & crashes.
Machine connects to net using "ppp0" (modem on phone), then if you
disconnect by unchecking "Enable Networking" & then rechecking "Enable
Networking", the Kernel Panics & crashes.
####################################################
First faced this problem with Kernel 3.8.0 so went back to using
3.7.9, then same story repeated with Kernel 3.8.1 & 3.8.2, currently
using Kernel 3.7.10. Think there is some REGRESSION in Kernel 3.8
I really apologize for not able to provide Apport logs as I have
uninstalled it a long time ago. I'm not a hard core techie, I'm self
taught Linux user & enthusiast. My main machine is Ubuntu since 2007.
