W^X violations are no longer permitted by default. A kernel log message
is generated, and mprotect/mmap return ENOTSUP. If the sysctl(8) flag
kern.wxabort is set then a SIGABRT occurs instead, for gdb use or coredump
creation.
W^X violating programs can be permitted on a ffs/nfs filesystem-basis,
using the "wxallowed" mount option. One day far in the future
upstream software developers will understand that W^X violations are a
tremendously risky practice and that style of programming will be
banished outright. Until then, we recommend most users need to use the
wxallowed option on their /usr/local filesystem. At least your other
filesystems don't permit such programs.
