Matthew Dillon fa7dd9c5bc Change the way ELF coredumps are handled. Instead of unconditionally ... skipping read-only pages, which can result in valuable non-text-related data not getting dumped, the ELF loader and the dynamic loader now mark read-only text pages NOCORE and the coredump code only checks (primarily) for complete inaccessibility of the page or NOCORE being set. Certain applications which map large amounts of read-only data will produce much larger cores. A new sysctl has been added, debug.elf_legacy_coredump, which will revert to the old behavior. This commit represents collaborative work by all parties involved. The PR contains a program demonstrating the problem.
