Many of them listed in opt_global.h which is not generated while building modules outside of a kernel and such modules never match real cofigured kernel. So, we should prevent our users from building obviously defective modules. Therefore, remove the root cause of the building of modules outside of a kernel - the possibility of building modules with DEBUG or KTR flags. And remove all of DEBUG printfs as it is incomplete and in threaded programms not informative, also a half of system call does not have DEBUG printf. For debuging Linux programms we have dtrace, ktr and ktrace ability.

Copy the CP, PTRIN, etc macros from freebsd32.h into a sys/abi_compat.h and replace existing definitation with includes where required. This eliminates duplicate code and allows Linux and FreeBSD compatability headers to be included in the same files.

For that remove bogus _packed attribute from struct l_sockaddr and use MI types for struct members. And continue to move into the linux_common module a code that is intended for both Linuxulator modules (both instruction set - 32 & 64 bit) or for external modules like linsysfs or linprocfs. To avoid header pollution introduce new sys/compat/linux_common.h header. 2018-06-15T14:41:51Z Ed Maste emaste@FreeBSD.org 2018-06-15T14:41:51Z urn:sha1:931e2a1a6e0d8ac7d99f48eb7fc744e3a40284f0 Existing linuxulator platforms (i386, amd64) support legacy syscalls, such as non-*at ones like open, but arm64 and other new platforms do not. Wrap these in #ifdef LINUX_LEGACY_SYSCALLS, #defined in the MD linux.h files. We may need finer grained control in the future but this is sufficient for now.

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. 2017-04-08T14:41:39Z Tai-hwa Liang avatar@FreeBSD.org 2017-04-08T14:41:39Z urn:sha1:7ece126ed8487b99874f6ecc3d0715d18ace60cd - renaming l_ifreq::ifru_metric to l_ifreq::ifru_ivalue; - adding a definition for ifr_ifindex which points to l_ifreq::ifru_ivalue.

Invert the native ipc structs to the Linux ipc structs convesion logic. Since 64-bit variant of ipc structs has more precision convert native ipc structs to the 64-bit Linux ipc structs and then truncate 64-bit values into the non 64-bit if needed. Unlike Linux, return EOVERFLOW if the values do not fit. Fix SYSV IPC for 64-bit Linuxulator which never sets IPC_64 bit. MFC after: 1 month
