These regress tests expect coredumps to be written so run them withulimit -c unlimited. Also simplify the logic a bit as requested by bluhm@.OK bluhm@ deraadt@
print the address of the "non-MAP_STACK stack", so it can be comparedagainst failure reported in dmesg (hmm, is it time to delete those faultmessages?)
test _exit(2) rather than exit(3) [to keep things simpler], andprint the stack address [for comparison in dmesg post-fault]
Add a test for stack pivots that trigger page faults."Regress is always open for commits" @deraadt
