New + architectures such as CHERI may support ZFS before they support DTrace + and the old model of WITHOUT_CDDL disabling both wasn't helpful. + + For compatiblity, the CDDL option remains and WITHOUT_CDDL implies + WITHOUT_DTRACE. WITHOUT_DTRACE also implies WITHOUT_CTF. + + As part of this change, largely convert cddl/*/Makefile to using the + more compact SUBDIR.${MK_<FOO>}+= form rather than using intermediate + variables. + + Reviewed by: markj + Obtained from: CheriBSD + Sponsored by: DARPA, AFRL + Differential Revision: https://reviews.freebsd.org/D35718 + +The files imported from FreeSD may be updated to a new FreeBSD baseline through +a patch set generated by this Git command: + +git format-patch 3bf66365129a13933f77d1f4421d5136861cffb4 -- \ +include/arpa/inet.h include/netdb.h include/termios.h sys/net/if.h \ +sys/netinet6/in6.h sys/netinet/in.h sys/netinet/tcp.h sys/sys/filio.h \ +sys/sys/ioccom.h sys/sys/_iovec.h sys/sys/mman.h sys/sys/poll.h \ +sys/sys/_sockaddr_storage.h sys/sys/socket.h sys/sys/sockio.h \ +sys/sys/syslog.h sys/sys/_termios.h sys/sys/ttycom.h sys/sys/ttydefaults.h \ +sys/sys/_uio.h sys/sys/uio.h sys/sys/un.h + +Use the follwing commands to map FreeBSD paths to Newlib paths: + +sed -i 's,include/arpa/inet.h,newlib/libc/sys/rtems/include/arpa/inet.h,g' *.patch +sed -i 's,include/netdb.h,newlib/libc/sys/rtems/include/netdb.h,g' *.patch +sed -i 's,include/termios.h,newlib/libc/sys/rtems/include/termios.h,g' *.patch +sed -i 's,sys/net/if.h,newlib/libc/sys/rtems/include/net/if.h,g' *.patch +sed -i 's,sys/netinet6/in6.h,newlib/libc/sys/rtems/include/netinet6/in6.h,g' *.patch +sed -i 's,sys/netinet/in.h,newlib/libc/sys/rtems/include/netinet/in.h,g' *.patch +sed -i 's,sys/netinet/tcp.h,newlib/libc/sys/rtems/include/netinet/tcp.h,g' *.patch +sed -i 's,sys/sys/filio.h,newlib/libc/sys/rtems/include/sys/filio.h,g' *.patch +sed -i 's,sys/sys/ioccom.h,newlib/libc/sys/rtems/include/sys/ioccom.h,g' *.patch +sed -i 's,sys/sys/_iovec.h,newlib/libc/sys/rtems/include/sys/_iovec.h,g' *.patch +sed -i 's,sys/sys/mman.h,newlib/libc/sys/rtems/include/sys/mman.h,g' *.patch +sed -i 's,sys/sys/poll.h,newlib/libc/sys/rtems/include/sys/poll.h,g' *.patch +sed -i 's,sys/sys/_sockaddr_storage.h,newlib/libc/sys/rtems/include/sys/_sockaddr_storage.h,g' *.patch +sed -i 's,sys/sys/socket.h,newlib/libc/sys/rtems/include/sys/socket.h,g' *.patch +sed -i 's,sys/sys/sockio.h,newlib/libc/sys/rtems/include/sys/sockio.h,g' *.patch +sed -i 's,sys/sys/syslog.h,newlib/libc/sys/rtems/include/sys/syslog.h,g' *.patch +sed -i 's,sys/sys/_termios.h,newlib/libc/sys/rtems/include/sys/_termios.h,g' *.patch +sed -i 's,sys/sys/ttycom.h,newlib/libc/sys/rtems/include/sys/ttycom.h,g' *.patch +sed -i 's,sys/sys/ttydefaults.h,newlib/libc/sys/rtems/include/sys/ttydefaults.h,g' *.patch +sed -i 's,sys/sys/_uio.h,newlib/libc/sys/rtems/include/sys/_uio.h,g' *.patch +sed -i 's,sys/sys/uio.h,newlib/libc/sys/rtems/include/sys/uio.h,g' *.patch +sed -i 's,sys/sys/un.h,newlib/libc/sys/rtems/include/sys/un.h,g' *.patch + +Some patches may change kernel space parts of the above header files.
