linuxolator: add netlink support

2022-10-01T14:16:45+00:00

Add the glue code to support netlink in Linuxolator.
linux_common(4) now depends on netlink(4).

All netlink protocol constants are consistent with the Linux version.
However, certain OS-specific constants such as AF_INET6, interface
flags or default routing table id, are different between FreeBSD and
Linux. Thus, it may be needed to rewrite some message parts or even
rewrite the whole message, adding or removing some TLVs. The core
netlink implementation code provides efficient rewriting callbacks
 which Linuxolator now uses.

linux_common: retire extra module version.

2021-05-26T05:34:32+00:00

The second 'linuxcommon' line was added by c66f5b079d2a259c3a65b1efe0f2143cd030dc52
but Linuxulator's modules dependend on 'linux_common'.
To avoid such mistakes in the future rename moduledata name and module
name to  'linux_common' and retire 'linuxcommon' line.

Move V4L feature declarations and DTrace provider definitions from

2020-12-06T10:58:55+00:00

linux_common.c to linux_util.c so they become available on i386.

linux_common.c defines the linux_common kernel module but this module does
not exist on i386 and linux_common.c is not included in the linux module.
linux_util.c is included in the linux_common module on amd64 and the linux
module on i386.

Remove linux_common.c from files.i386 again.  It was added recently in
r367433 when the DTrace provider definitions were moved.

The V4L feature declarations were moved to linux_common in r283423.

linux(4): Fix loadable modules after r367395

2020-11-06T22:04:57+00:00

Move dtrace SDT definitions into linux_common module code.  Also, build
linux_dummy.c into the linux_common kld -- we don't need separate
versions of these stubs for 32- and 64-bit emulation.
