This was the intention from the start, but due to a logic error in the
handling of slices the implementation only handled minimum 8 character
strings.
This commit also improves the tests.

This adds support for addressing these services using AF_IUCV.

Some systems (e.g. the linux-arm and linux-arm64-packet builders) return
EPERM instead of ENOSYS on unimplemented syscalls. Fall back to the
existing glibc-like implementation in Faccessat in this case as well.
This fixes tests on the linux-arm and linux-arm64-packet builders after

These are Linux-specific system calls for efficiently reading and

A new RemoteIovec type is added for use in these wrappers, as Iovec's

CL 223698 changed the types of the Fstypename, Mntfromname and Mntonname

The regression test included in this change verifies that the type is,
in fact, equivalent, while allowing the actual header definitions to
avoid importing the (relatively heavy) "reflect" package itself.
This change is loosely based on Keyan Pishdadian's draft in CL 230557.

openat2 is a new syscall added to Linux 5.6. It provides a superset
of openat(2) functionality, providing a way to extend it in the future,
and (for now) adding flags telling the kernel how to resolve the path.
For more info on openat2, see https://lwn.net/Articles/803237/
A primitive test case is added to check that Openat2 works as
it should. Tested to skip on kernel 5.5 and pass on 5.6.

I just created a couple of virtual machines/QEMU instances containing
stock copies of FreeBSD 12.1-RELEASE. On these systems I ran mkall.sh,
thereby bringing the definitions in sync with that version of FreeBSD.
I also attempted to bring the GOOS=freebsd GOARCH=arm port up to date,
but was unfortunately not able to do so. There doesn't seem to be any
documentation on how to bring this port of FreeBSD up on an emulator.
The only option seems to be to use physical hardware.

Add constants and types to support IP-encapsulated L2TP/RFC3931
tunnels on Linux systems.
The L2TP subsystem for IP encapsulated tunnels hooks into the inet
kernel code using a specific IP protocol value. In order to handle
this, anyToSockaddr now has to query the socket protocol type using
GetsockoptInt for the AF_INET and AF_INET6 address families.
Although this change is reasonably simple, unit tests have been added
to validate handling of the new types.
