Drop cloudabi

Browse Source 
According to https://github.com/NuxiNL/cloudlibc:
CloudABI is no longer being maintained. It was an awesome experiment,
but it never got enough traction to be sustainable.

There is no reason to keep it in FreeBSD.

.Dt CLOUDABI 4
.Os
.Sh NAME
.Nm cloudabi ,
.Nm cloudabi32 ,
.Nm cloudabi64
.Nd CloudABI support
.Sh SYNOPSIS
Support for 32-bit CloudABI executables can be compiled into the kernel
by adding this line to the kernel configuration file:
.Bd -ragged -offset indent
.Cd "options COMPAT_CLOUDABI32"
.Ed
.Pp
Similarly,
support for 64-bit CloudABI executables can be enabled by adding this
line:
.Bd -ragged -offset indent
.Cd "options COMPAT_CLOUDABI64"
.Ed
.Pp
CloudABI support can also be loaded at boot time from
.Xr loader.conf 5 :
.Bd -literal -offset indent
cloudabi_load="YES"
cloudabi32_load="YES"
cloudabi64_load="YES"
.Ed
.Sh DESCRIPTION
CloudABI is a POSIX-like pure capability-based runtime environment,
similar to
.Xr capsicum 4 .
It can be used to develop applications that are cross-platform,
easier to test,
and hardened against security exploits.
.Pp
Support for CloudABI on
.Fx
consists of three separate kernel modules.
The
.Nm cloudabi
kernel module implements all of the system calls that do not depend on
data structures that differ between hardware architectures.
.Pp
The
.Nm cloudabi32
and
.Nm cloudabi64
kernel modules provide implementations of all of the machine-dependent
system calls,
assuming that pointers stored in data structures are either 32 bits or
64 bits in size.
These modules also provide the image activators that load and start ELF
executables.
.Pp
Though the
.Nm cloudabi
module can be loaded on any architecture supported by
.Fx ,
the
.Nm cloudabi32
module is only available on amd64, arm64, armv6, armv7 and i386.
The same holds for the
.Nm cloudabi64
module,
which is only available for amd64 and arm64.
.Pp
A full cross compilation toolchain for CloudABI is available in the
.Pa devel/cloudabi-toolchain
port.
.Pp
The
.Pa sysutils/cloudabi-utils
port provides the
.Xr cloudabi-run 1
utility.
.Xr cloudabi-run 1
can be used to safely execute CloudABI processes with access to a
restricted set of resources.
.Sh SEE ALSO
.Xr cloudabi-run 1 ,
.Xr capsicum 4 ,

CloudABI support first appeared in

/*
* Copying pathnames from userspace to kernelspace.
*
* Unlike most operating systems, CloudABI doesn't use null-terminated
* pathname strings. Processes always pass pathnames to the kernel by
* providing a base pointer and a length. This has a couple of reasons:
*
* - It makes it easier to use CloudABI in combination with programming
* languages other than C, that may use non-null terminated strings.
* - It allows for calling system calls on individual components of the
* pathname without modifying the input string.
*
* The function below copies in pathname strings and null-terminates it.
* It also ensure that the string itself does not contain any null
* bytes.
*
* TODO(ed): Add an abstraction to vfs_lookup.c that allows us to pass
* in unterminated pathname strings, so we can do away with
* the copying.
