Although there are already multiple tests in the tests collection
that utilize sendfile(2) support over unix/stream socket, they all
don't exercise the asynchronous part of the operation. This test
framework, however, uses a trick to toggle true async operation and
guarantee that pr_ready method of unix/stream is also tested.

The fact that an accept filter needs to be cleared first before setting to
a different one isn't properly documented. The requirement that the
socket needs already be listening, although trivial, isn't documented
either. At least return a more meaningful error than EINVAL for an
existing filter. Cover this with a test case.
Put this simple test into an existing file. We don't have a designated
file for all unix/stream tests. There is extensive unix_seqpacket_test,
but (at least right now) unix/seqpacket is not a superset of unix/stream,
but a different implementation. We have one file that does one test for
unix/stream - unix_socketpair_test. So rename it to unix_stream and start
collecting all unix/stream tests in it.
Verify that a capability violation is recorded when shm_open(2) is called

Introduce regression tests for ktrace(2) that target capability
violations.
These test cases ensure that ktrace(2) records these violations:
- CAPFAIL_NOTCAPABLE
- CAPFAIL_INCREASE
- CAPFAIL_SYSCALL
- CAPFAIL_SIGNAL
- CAPFAIL_PROTO
- CAPFAIL_SOCKADDR
- CAPFAIL_NAMEI
- CAPFAIL_CPUSET
A portion of these test cases create processes that do NOT enter
capability mode, but raise violations. This is intended behavior.
Users may run `ktrace -t p` on non-Capsicumized programs to detect
violations that would occur if the process were in capability mode.

These tests were not testing conformance to the specification, rather than
the limitation of our implementation. The specification doesn't say that
a SOCK_SEQPACKET shall ever return EMSGSIZE. It says:
The SOCK_SEQPACKET socket type is similar to the SOCK_STREAM type,
and is also connection-oriented. The only difference between these
types is that record boundaries are maintained using the
SOCK_SEQPACKET type. A record can be sent using one or more output
operations and received using one or more input operations, but a
single operation never transfers parts of more than one record.
Record boundaries are visible to the receiver via the MSG_EOR flag
in the received message flags returned by the recvmsg() function. It
is protocol-specific whether a maximum record size is imposed.
The EMSGSIZE is specified as 'message is too large to be sent all at once,
as the socket requires'. Indeed existing implementation that has
unix/seqpacket marked as PR_ATOMIC has such a limitation. But future
implementation won't have, thus remove the tests.

The PF_UNIX/SOCK_SEQPACKET was marked as PR_ATOMIC and that made
soreceive_generic() to treat it pretty much as a datagram socket.
However, POSIX says:
The SOCK_SEQPACKET socket type is similar to the SOCK_STREAM type,
and is also connection-oriented. The only difference between these
types is that record boundaries are maintained using the
SOCK_SEQPACKET type. A record can be sent using one or more output

What the test was doing is checking if MSG_TRUNC would report the space
required to return up the end of next mbuf record in the socket buffer.
Apparently the test assumed that this boundary is defined by the write(2)
size on the peer socket. This was true in test conditions, but I'm not
sure it would always be true - sbcompress() may merge mbufs. Anyway, the
mbuf boundaries are internal socket buffer implementation, they are not
SOCK_SEQPACKET records. The records need to be explicitly marked with
MSG_EOR by sender, and the test definitely wasn't doing that.

The test needs to be performed in a new process that was forked with
RFCFDG flag. The will guarantee that the table will start to grow from 20
file descriptors, no matter what kyua(1) or a bare shell was doing before
executing this test. This should fix repetitive test runs from a shell
as well as failures with kyua(1) in some environments.
This reverts commit fa6a02f50e.
It makes the test less probable to fail, but it doesn't fix the
root issue - that on entry the parent process may have already
a large file descriptor table.
This should fix the test failing on some machines/conditions/runs. This
won't fix failures in standalone run, but should fix kyua(1) runs.
Currently with standalone run it will usually fail because the 40-sized
allocation is skipped (see details below).
This matches what forking test does: open 128 files in the parent and 128
in the child. There should actually be no difference where and when the
files are open, but let's mimic the forking test, and open more files in
the spawned thread. Also opening from two different contexts adds a bit
more entropy to the test.
What the test does it checks that fdgrowtable() has been called at least
three tmes for the test process, and the old tables are still on the free
list as long as other execution contexts exist. Under kyua(1) control the
first call grows the table from 20 to 40, but the original table of 20 is
an embedded one, thus is not put on the free list. Passing 40 open files
the table grows to 128 and first old table lands on the free list. Passing
128 open file the table grows to 256 and a second old table lands on the
free list. After that the test would pass. The threaded test was one
open file off before this fix sometimes.
This test runs several scenarios when sleep(9) on a listen(2)ing socket is
interrupted by shutdown(2) or by close(2). What should happen in that
case is not specified, neither is documented. However, there is certain
behavior that we have and this test makes sure it is preserved. There is
software that relies on it, see bug 227259. This test is based on
submission with this bug, bugzilla attachment 192260.
The test checks TCP and unix(4) stream socket behavior and SCTP can be
added easily if needed.
The test passes on FreeBSD 11 to 15. It won't pass on FreeBSD 10,
although the wakeup behavior of shutdown(2) is the same, but it doesn't
return error.

If socket has data interleaved with control it would never allow to read
two pieces of data, neither two pieces of control with one recvmsg(2). In
other words, presence of control makes a SOCK_STREAM socket behave like
SOCK_SEQPACKET, where control marks the records. This is not a documented
or specified behavior, but this is how it worked always for BSD sockets.
If you look closer at it, this actually makes a lot of sense, as if it
were the opposite both the kernel code and an application code would
become way more complex.
The change made recvfd_payload() to return received length and requires
caller to do ATF_REQUIRE() itself. This required a small change to
existing test rights_creds_payload. It also refactors a bit f28532a0f3,
pushing two identical calls out of TEST_PROTO ifdef.

This would previously return 1 if the slave side of the pts was closed
to force an application to read() from it and observe the EOF, but it's

In my test suite runs I occasionally see shutdown(2) fail with
ECONNRESET rather than ENOTCONN. soshutdown(2) will return ENOTCONN if
the socket has been disconnected (synchronized by the socket lock), and
tcp_usr_shutdown() will return ECONNRESET if the inpcb has been dropped
(synchronized by the inpcb lock). I think it's possible to pass the
first check in soshutdown() but fail the second check in
tcp_usr_shutdown(), so modify the KTLS tests to permit this.
