Description Martin Ettl 2009-03-28 23:47:21 UTC

Hi,

i found a possible error in the souce code in file linux-2.6.29/arch/ia64/sn/kernel/io_common.c at line 443 


look at line 443:
sprintf(address, "%s^%d", address, geo_slot(geoid));

I found this by using a static code analysis tool (cppcheck)

report generated by cppcheck:

[linux-2.6.29/arch/ia64/sn/kernel/io_common.c:443]: (error) Overlapping data buffer address

Best regards

Ettl Martin
