[Kernel-packages] [Bug 1189998] Re: bluetooth disconnection corrupts memory and causes kernel panic
I managed to find one more bug report similar to this one. So now there
are at least four bug reports (including this one) here in Launchpad on
this problem:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165433
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1189998
https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1256811
Anyway, if these are about the same bug that I think they are, the bug
has now been completely fixed in kernel version 3.14, though kernel
version 3.12 included some of the fix. Also there was one previous fix
that is also needed that I think was backported to stable before 3.12.
I think I manged to list all the necessary commits, Here are links to
the commits, in case they need to be backported:
The first fix (pre 3.12?):
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1d9e689c934bd5ecb0f273c6c65e0655c5cfee5f
The fixes in 3.12:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=396dc223dd36edd218650d042a07c5e61f022c5b

Bug description:
This bug is present on kernels v3.8-rc1 and beyond and was exposed by commit
ecbbfd44.
To reproduce:
1) Pair a bluetooth device that is capable of being easily powered down (a
phone for example)
2) Configure /etc/bluetooth/rfcomm.conf to connect to device. For example:
rfcomm0 {
bind no;
device XX:XX:XX:XX:XX:XX;
channel XX;
comment phone;
}
3) Type 'rfcomm connect 0'.
4) On the device power down the bluetooth component or power down the device.
5) Eventually the machine will crash, I've found that exec'ing another
program will cause the crash easily.

[Kernel-packages] [Bug 1189998] Re: bluetooth disconnection corrupts memory and causes kernel panic
Gianluca Azolin's patches were merged to net-next day before yesterday.
And yesterday they were merged to Linus' master branch. So patches will
be in 3.12 rc1.

[Kernel-packages] [Bug 1189998] Re: bluetooth disconnection corrupts memory and causes kernel panic
Gianluca Anzolin writes on bluetooth-linux mailing list that though his
tty refcount patch series is needed, more work is required to fix the
problem. If I understood his mailing list message correctly, the system
locks up when the device is released even after his patches have been
applied.

bluetooth disconnection corrupts memory and causes kernel panic
Status in “linux” package in Ubuntu:

Status in “linux” source package in Raring:
Confirmed
Status in “linux” source package in Saucy:

Bug description:
This bug is present on kernels v3.8-rc1 and beyond and was exposed by commit
ecbbfd44.
To reproduce:
1) Pair a bluetooth device that is capable of being easily powered down (a
phone for example)
2) Configure /etc/bluetooth/rfcomm.conf to connect to device. For example:
rfcomm0 {
bind no;
device XX:XX:XX:XX:XX:XX;
channel XX;
comment phone;
}
3) Type 'rfcomm connect 0'.
4) On the device power down the bluetooth component or power down the device.
5) Eventually the machine will crash, I've found that exec'ing another
program will cause the crash easily.

The fix being discussed on Bluetooth mailing list has already been
merged to bluetooth-next (and wireless-next). The fix should find its
way to mainline kernel (probably 3.12).

However, the patch series is apparently too extensive to consider for
-stable [1]. So another solution is required for stable kernels. Though
no one seems to know what the right solution for stable kernels is [2].

Title:
bluetooth disconnection corrupts memory and causes kernel panic
Status in “linux” package in Ubuntu:
Confirmed
Status in “linux” source package in Raring:
Confirmed
Status in “linux” source package in Saucy:
Confirmed
Bug description:
This bug is present on kernels v3.8-rc1 and beyond and was exposed by commit
ecbbfd44.
To reproduce:
1) Pair a bluetooth device that is capable of being easily powered down (a
phone for example)
2) Configure /etc/bluetooth/rfcomm.conf to connect to device. For example:
rfcomm0 {
bind no;
device XX:XX:XX:XX:XX:XX;
channel XX;
comment phone;
}
3) Type 'rfcomm connect 0'.
4) On the device power down the bluetooth component or power down the device.
5) Eventually the machine will crash, I've found that exec'ing another
program will cause the crash easily.
