Re: kern/53232 (mprotect() modifications of stack pages)

Synopsis: mprotect() modifications of stack pages

State-Changed-From-To: open->closed
State-Changed-When: Sun, 29 Apr 2018 19:30:25 +0000
Not a bug, even documented in mprotect(2): you can not mprotect to
something less restrictive than the original mmap(2) with pax mprotect
Workaround: mmap with PROT_READ|PROT_WRITE and mprotect() to 0, then
later it is possible to mprotect(PROT_READ|PROT_WRITE) again.
