In r231994, an attempt was made to fix crypt(3) failure returns (NULL).
However, instead of treating crypt(3) failure as authentication failure,
some of the changes treated crypt(3) failure as authentication success.
This is wrong.
r324225 fixed this for ppp, which also inspired this review. The other
changes in the 231994 revision were audited for correctness and look ok.

Violators may define _WANT_SOCKET and _WANT_UNPCB respectively and
are not guaranteed for stability of the structures. The violators
list is the the usual one: libprocstat(3) and netstat(1) internally
and lsof in ports.
In struct xunpcb remove the inclusion of kernel structure and add
a bunch of spare fields. The xsocket already has socket not included,
but add there spares as well. Embed xsockbuf into xsocket.
Sort declarations in sys/socketvar.h to separate kernel only from
userland available ones.

It's now possible to use Broadcom functions to read the I/O registers of
SDIO card. The functions were copied from the BSD-licensed Broadcom Linux driver
as-is. To make it possible, a small Linux compatibility layer was introduced.
Currently the card responds with the correct version number ("magic")
when reading the corresponding address.

Now that CloudABI's sockets API has been changed to be addressless and
only connected socket instances are used (e.g., socket pairs), they have
become fairly similar to pipes. The only differences on CloudABI is that
socket pairs additionally support shutdown(), send() and recv().
To simplify the ABI, we've therefore decided to remove pipes as a
separate file descriptor type and just let pipe() return a socket pair
of type SOCK_STREAM. S_ISFIFO() and S_ISSOCK() are now defined
identically.
Move tables that were previously in truss over to libsysdecode. truss
output is unchanged, but kdump has been updated to decode these fields.
In addition, sysdecode_sysarch_number() should support all platforms
whereas the old table in truss only supported x86.
In the case where write(2) does not return -1, it does not initialize errno.
This can happen when a broken pipe causes a short write.
I attempted to adapt the submitted test case to ATF but could not figure out
how to make the test run in the ATF environment. So the aborted test is
left disabled, in case someone would like to run it manually or fix it.

Specifically, decode the siginfo structure returned by sigtimedwait(),
sigwaitinfo(), and wait6(). While here, also decode the signal number
returned in the second argument to sigwait().
kresolve_list() is calling many kldsym(2). Removing that call on when collecting
stats for the running kernel improves the startup time and CPU usage.

Now that all of the packaged software has been adjusted to either use
Flower (https://github.com/NuxiNL/flower) for making incoming/outgoing
network connections or can have connections injected, there is no longer
need to keep accept() around. It is now a lot easier to write networked
services that are address family independent, dual-stack, testable, etc.
Remove all of the bits related to accept(), but also to
getsockopt(SO_ACCEPTCONN).
Decode fields from the siginfo_t stored in the PT_LWPINFO structure when a
signal is caught by a traced process. This includes the signal code
(si_code) as well as additional members such as si_addr, si_pid, etc.
With Flower (CloudABI's network connection daemon) becoming more
complete, there is no longer any need for creating any unconnected
sockets. Socket pairs in combination with file descriptor passing is all
that is necessary, as that is what is used by Flower to pass network
connections from the public internet to listening processes.
Remove all of the kernel bits that were used to implement socket(),
listen(), bindat() and connectat(). In principle, accept() and
SO_ACCEPTCONN may also be removed, but there are still some consumers
left.

fgrep/grep -F will error out at runtime if compiled with a regex(3)
that does not define REG_NOSPEC or REG_LITERAL. glibc is one such regex(3)
implementation, and as it turns out they don't support literal matching at
all.
Provide a primitive literal matcher for use with glibc and other
implementations that don't support literal matching so that we don't
completely lose fgrep/grep -F if compiled against libgnuregex on stable/10,
stable/11, or other systems that we don't necessarily support.
This is a wholly unoptimized implementation with no plans to optimize it as
of now. This is due to both its use-case being primarily on unsupported
systems in the near-distant future and that it's reinventing the wheel that
we already have available as a feature of regex(3).
