Ondřej Surý 58bd26b6cf Update the copyright information in all files in the repository
This commit converts the license handling to adhere to the REUSE
specification.  It specifically:

1. Adds used licnses to LICENSES/ directory

2. Add "isc" template for adding the copyright boilerplate

3. Changes all source files to include copyright and SPDX license
   header, this includes all the C sources, documentation, zone files,
   configuration files.  There are notes in the doc/dev/copyrights file
   on how to add correct headers to the new files.

4. Handle the rest that can't be modified via .reuse/dep5 file.  The
   binary (or otherwise unmodifiable) files could have license places
   next to them in <foo>.license file, but this would lead to cluttered
   repository and most of the files handled in the .reuse/dep5 file are
   system test files.

Notes for BIND 9.17.3
---------------------
New Features
~~~~~~~~~~~~
- New ``rndc`` command ``rndc dnssec -status`` shows the current DNSSEC
policy and keys in use, the key states, and rollover status.
:gl:`#1612`
- Added support in the network manager for initiating outgoing TCP
connections. :gl:`#1958`
Feature Changes
~~~~~~~~~~~~~~~
- Disable and disallow static linking of BIND 9 binaries and libraries
as BIND 9 modules require ``dlopen()`` support and static linking also
prevents using security features like read-only relocations (RELRO) or
address space layout randomization (ASLR) which are important for
programs that interact with the network and process arbitrary user
input. :gl:`#1933`
- As part of an ongoing effort to use :rfc:`8499` terminology,
``primaries`` can now be used as a synonym for ``masters`` in
``named.conf``. Similarly, ``notify primary-only`` can now be used as
a synonym for ``notify master-only``. The output of ``rndc
zonestatus`` now uses ``primary`` and ``secondary`` terminology.
:gl:`#1948`
Bug Fixes
~~~~~~~~~
- A race condition could occur if a TCP socket connection was closed
while ``named`` was waiting for a recursive response. The attempt to
send a response over the closing connection triggered an assertion
failure in the function ``isc__nm_tcpdns_send()``. :gl:`#1937`
- A race condition could occur when ``named`` attempted to use a UDP
interface that was shutting down. This triggered an assertion failure
in ``uv__udp_finish_close()``. :gl:`#1938`
- Fix assertion failure when server was under load and root zone had not
yet been loaded. :gl:`#1862`
- ``named`` could crash when cleaning dead nodes in ``lib/dns/rbtdb.c``
that were being reused. :gl:`#1968`
- ``named`` crashed on shutdown when a new ``rndc`` connection was
received during shutdown. This has been fixed. :gl:`#1747`
- The DS RRset returned by ``dns_keynode_dsset()`` was used in a
non-thread-safe manner. This could result in an INSIST being
triggered. :gl:`#1926`
- The ``primary`` and ``secondary`` keywords, when used as parameters
for ``check-names``, were not processed correctly and were being
ignored. :gl:`#1949`
- ``rndc dnstap -roll <value>`` did not limit the number of saved files
to ``<value>``. :gl:`!3728`
- The validator could fail to accept a properly signed RRset if an
unsupported algorithm appeared earlier in the DNSKEY RRset than a
supported algorithm. It could also stop if it detected a malformed
public key. :gl:`#1689`
- The ``blackhole`` ACL was inadvertently disabled for client queries.
Blocked IP addresses were not used for upstream queries but queries
from those addresses could still be answered. :gl:`#1936`
