by using a patched version of Go 1.18. The necessary changes have since

Mount the data volume for the Docker-based builder at x/sys instead of
x/sys/unix.
The x/sys/go.mod file was not included in the data volume when mounting
x/sys/unix. This breaks module-aware go commands that run within the
Docker container.
Fix this problem by mounting the volume at x/sys and updating the
working directory of the builder accordingly.

This change adds (most) of the ioctl API for the Linux HIDRAW interface.
Reading and writing non-numbered HID reports is done using the read and
write system calls respectively.
Some of the HIDIOC* request numbers are exported directly while others
are kept unexported. This is because some of the #defines require a len
attribute that doesn't have a specific well defined value.
Wrapper types are added for most of the request numbers as is standard.
No wrapper is added for HIDIOCGRDESCSIZE as it would just be
IoctlGetUint32.
The HIDIOC[GS]FEATURE, HIDIOC[GS]INPUT and HIDIOC[GS]OUTPUT request
numbers, which are required for numbered HID reports, are entirely
ommitted as the len attribute has to be a runtime variable. These could
be added later by doing something like
`HIDIOCGFEATURE(0) | (len << _IOC_SIZESHIFT)`,
with care taken that len doesn't overflow _IOC_XSIZEMASK.
Outdated documentation for the HIDRAW interface is available at:
https://www.kernel.org/doc/Documentation/hid/hidraw.txt.

Because the C struct sockaddr_tipc makes use of a union for its addr
field, I have created a wrapping layer in SockaddrTIPC that uses
an interface to determine which variant is in use.
Tests accompany this change due to the complexity of this code. There
is currently little test coverage in the Sockaddr-related code, but
perhaps this is something that could be picked up as a relatively
straightforward task for a new contributor.

Add IoctlRetInt() for ioctls that use syscall's return value
as an output parameter. Add a unit test for Linux, and the
NS_GET_ defines that it requires (see ioctl_ns(2)).
Motivation:
Currently, x/sys/unix provides a few functions to deal with ioctls.
In particular, IoctlGetInt(), which "performs an ioctl operation
which gets an integer value". It does that by passing a pointer
to an integer to a syscall and returning that integer. The value
returned from syscall is treated as success/failure flag
(0 means success, -1 means failure, and in such case errno
is used to figure out the underlying error).
It appears that there are a few ioctls in Linux and at least one
in Solaris, which do not use the above way to return an int, instead
they use the syscall's return value (in case it's not negative).
As Linux ioctl(2) man page says,
> RETURN VALUE
> Usually, on success zero is returned. A few ioctl() requests
> use the return value as an output parameter and return
> a nonnegative value on success. On error, -1 is returned,
> and errno is set appropriately.
Currently I am aware of at least 6 Linux ioctls that do that
(return the value directly):
* LOOP_CTL_* ioctls on /dev/loop-control (all 3 of them). Source: loop(4)
* NS_* ioctls (3 out of 4) on /proc/PID/ns/*. Source: ioctl_ns(2)
And one in Solaris:
* I_FIND ioctl, source: streamio(7i).
There might be some more ioctls like the ones above, but since
ioctls are scarcely documented, it is hard to say how many more.
Obviously, using IoctlGetInt() for such ioctls would be a big
mistake, as 0 will always be returned. For example, there was
a bug in Docker's pkg/loopback (moby/moby#39801).
