* (1) called invalid address

* (2) read or write invalid address
|
|
* (3) received signal
|
|
*
|
|
* Detail:
|
|
* (1) called invalid address
|
|
* In this case, saved ip is invalid address.
|
|
* It needs to just save the address for the information,
|
|
* skip the frame, and restore the frame calling the
|
|
* invalid address from %rsp.
|
|
* The problem is how to check whether the ip is valid or not.
|
|
* This code uses mincore(2) and assume the address's page is
|
|
* incore/referenced or not reflects the problem.
|
|
* Note that High Sierra's mincore(2) may return -128.
|
|
* (2) read or write invalid address
|
|
* saved ip is valid. just restart backtracing.
|
|
* (3) received signal in user space
|
|
* Same as (2).
|
|
* (4) received signal in kernel
|
|
* In this case saved ip points just after syscall, but registers are
|
|
* already overwritten by kernel. To fix register consistency,
|
|
* skip libc's kernel wrapper.
|
|
* To detect this case, just previous two bytes of ip is "\x0f\x05",
|
|
* syscall instruction of x86_64.
