문제
I am using mmap for allocation memory and mark some pages as PROT_READ and few as PROT_NONE using mprotect. my implementation has logic based on the memory permission. Currently I have the memory location info, how do I get its current protection state? (PROT_READ/PROT_NONE)
해결책
I don't know if there's a syscall to retrieve this information.
Absolute worst case you could parse /proc/<pid>/maps
.
