The windowsize option permits multiple blocks to be transmitted
before the receiver sends an ACK improving throughput for larger
files.

Transferring files in netascii format requires, among other things,
translating all CR characters to a CR,NUL pair. tftpd does this correctly
except when the CR occurs as the last octet of a packet. In that case, it
erroneously drops the NUL which should be part of the following packet. The
bug was caused by using 0 as a sentinel value in a variable that could
legitimately hold 0. Fix it by switching the sentinel value to -1.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
No functional change intended.
tftp implementation. The synchnet() function
was converted to a no-op when the new TFTP implementation
was committed to FreeBSD. However, this function, as it was
in the older code, is needed
in order to synchronize between the tftpd server and tftp clients,
which may be buggy.
Specifically, we had a buggy TFTP client which would send
TFTP ACK packets for non-TFTP packets, which would cause
the count of packets to get out of whack, causing transfers
to fail with the new TFTPD implementation.
