I am new to kernel hacking and am facing problems in tryingstatic intto peek at the
runtime values of some kernel variables using gdb.
I am issuing the gdb command as follows:
gdb vmlinux /proc/kcore
This displays the message
/proc/kcore: Operation not permitted
before the (gdb) prompt is displayed.
gdb then prints a value of 0 for any valid variable that is requested.
vmlinux appears to be OK, as gdb correctly identifies undefined variables.
The problem seems to be with /proc/kcore. This file has a permission of 400. I
am using the Red Hat distribution.
Any help is appreciated. Thanks,
