* In the setup phase, wait for the server to start (or fail to start)
before proceeding with the test. This makes it possible to write test
cases that don't expect a response from the server without ending up
in a race over the server PID file.
* After running each test, wait up to 30 seconds for the server to exit
and check that the exit status matches what the test case says to
expect (usually 0).
* We still kill and collect the server in the cleanup phase, in case the
test ended early.

Repeating the default WARNS here makes it slightly more difficult to
experiment with default WARNS changes, e.g. if we did something absolutely
bananas and introduced a WARNS=7 and wanted to try lifting the default to
that.
Drop most of them; there is one in the blake2 kernel module, but I suspect
it should be dropped -- the default WARNS in the rest of the build doesn't
currently apply to kernel modules, and I haven't put too much thought into
whether it makes sense to make it so.
Assume gcc is at least 6.4, the oldest xtoolchain in the ports tree.
Assume clang is at least 6, which was in 11.2-RELEASE. Drop conditions
for older compilers.

If tftpd receives a command with an unknown opcode, it simply exits 1. It
doesn't send an ERROR packet, and the client will hang waiting for one. Fix
it.
PR: 226005
MFC after: 3 weeks
On a WRQ (write request) tftpd checks whether the client has access
permission for the file in question. If not, then the write is prevented.
However, tftpd doesn't reply with an ERROR packet, nor does it abort.
Instead, it tries to receive the packet anyway.
The symptom is slightly different depending on the nature of the error. If
the target file is nonexistent and tftpd lacks permission to create it, then
tftpd will willingly receive the file, but not write it anywhere. If the
file exists but is not writable, then tftpd will fail to ACK to WRQ.

tftpd(8) says that files may only be written if they already exist and are
publicly writable. tftpd.c verifies that a file is publicly writable if it
uses an absolute pathname. However, if the pathname is relative, that check
is skipped. Fix it.
Note that this is not a security vulnerability, because the transfer
ultimately doesn't work unless the file already exists and is owned by user
nobody. Also, this bug does not affect the default configuration, because
the default uses the "-s" option which makes all pathnames absolute.

On an RRQ, tftpd doesn't exit as soon as it's finished receiving a file.
Instead, it waits five seconds just in case the client didn't receive the
server's last ACK and decides to resend the final DATA packet.
Unfortunately, this created a 5 second delay from when the client thinks
it's done sending the file, and when the file is available for other
processes.
Fix this bug by closing the file as soon as receipt is finished.

tftpd(8) is difficult to test in isolation due to its relationship with
inetd. Create a test program that mimics the behavior of tftp(1) and
inetd(8) and verifies tftpd's response in several different scenarios.
These test cases cover all of the basic TFTP protocol, but not the optional
parts.
