Hi,
I want to relate trace events to source code. For testing, I did a
small C program that does a file access. In the event
kernel.syscall_entry sys_access, I got the instruction pointer
ip=0x7fa4fba26ee7. I dumped the process memory map from
/proc/$PID/maps, and this address doesn't fit in the process memory
space. It's somewhat close to libc addresses, that are in the range of
0x7f6471f56000-0x7f64724fc000.
Another example, inside a TRAP, I got two addresses,
ip=0xffffffff812c722b and address=0x7fa4fba2cbc0, those two addresses
doesn't map in the process space.
First, what is the difference between ip and address attribute? And
wow does the ip can be converted back to the process address space?
Cheer,
Francis
