Andrew Turner	df696a2fb6	Have the coredump_phnum test ask for the page size ... The page size may be dynamically selected on boot. Have the coredump_phnum test helper ask the kernel for the correct value. Sponsored by: The FreeBSD Foundation	2022-04-07 15:59:32 +01:00
Ed Maste	8ec4c5dae3	Fix coredump_phnum test with ASLR enabled by default ... coredump_phnum intends to generate a core file with many PT_LOAD segments. Previously it called mmap() in a loop with alternating protections, relying on each mapping following the previous, to produce a core file with many page-sized PT_LOAD segments. With ASLR on we no longer have this property of each mmap() following the previous. Instead, perform a single allocation, and then use mprotect() to set alternating pages to PROT_READ.
