HW configuration: MX51 EVK board
SW configuration:
1. Install xserver-xorg-input-evtouch page (version: 0.8.8-0ubuntu6.1)
2. Add fdi file by "vi /usr/share/hal/fdi/policy/20thirdparty/50-mxc-ts.fdi":
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="info.product" contains="mxc_ts">
<merge key="input.x11_driver" type="string">evtouch</merge>
</match>
</device>
</deviceinfo>
3. reboot the board, X crash. The backtrace is as follows:
Program received signal SIGSEGV, Segmentation fault.
0x402edae4 in strlen () from /lib/libc.so.6
(gdb) backtrace
#0 0x402edae4 in strlen () from /lib/libc.so.6
#1 0x00096a4c in xf86optionListCreate ()
#2 0x0008f8d8 in xf86CollectInputOptions ()
#3 0x42d46b0c in EVTouchPreInit (drv=<value optimized out>, dev=0x329b88,
flags=<value optimized out>) at evtouch.c:1167
#4 0x000861c8 in ?? ()
#5 0x000861c8 in ?? ()
However if i down-grade xserver-xorg-input-evtouch to version 0.8.8-0ubuntu3, Touch screen works fine.
So what's the possible difference cause this issue? |
[Impact]
A bug in the implementation of the -evtouch driver's input configuration can lead to crashes due to failing to detect the end-of-list marker for the configuration options list.
[Development Solution]
Patch incorporated into -evtouch in natty.
[Stable Solution]
We carry the same upstream version of -evtouch in lucid, maverick, and natty, so the same patch can be used in all three versions without modification.
[Test Case]
See original report
[Regression Potential]
I think basically none. This is clearly incorrect code.
The scope of a regression would be quite constrained as well, since -evtouch is used only for a focused class of hardware.
