Petr Špaček 53a5776025 Hyperlink program names to their manual pages
Use the new role :iscman: to replace all occurences or ``binary``
with :iscman:`binary`, creating a hyperlink to the manual page.

Generated using:
    find bin -name *.rst | xargs fgrep --files-with-matches '.. iscman' | xargs -I{} -n1 basename {} .rst > /tmp/progs
    for PROG in $(cat /tmp/progs); do find -name '*.rst' | xargs sed -i -e "s/\`\`$PROG\`\`/:iscman:\`$PROG\`/g"; done

Additional hand-edits were done mainly around filter-aaaa and
filter-a which are program names and and option names at the
same time. Couple more edits was neede to fix .rst syntax broken by
automatic replacement.

Notes for BIND 9.17.5
---------------------
New Features
~~~~~~~~~~~~
- Add a new :iscman:`rndc` command, :option:`rndc dnssec -checkds <rndc dnssec>`, which signals to
:iscman:`named` that a DS record for a given zone or key has been published
or withdrawn from the parent. This command replaces the time-based
``parent-registration-delay`` configuration option. :gl:`#1613`
- Log when :iscman:`named` adds a CDS/CDNSKEY to the zone. :gl:`#1748`
Removed Features
~~~~~~~~~~~~~~~~
- The ``--with-gperftools-profiler`` ``configure`` option was removed.
To use the gperftools profiler, the ``HAVE_GPERFTOOLS_PROFILER`` macro
now needs to be manually set in ``CFLAGS`` and ``-lprofiler`` needs to
be present in ``LDFLAGS``. :gl:`!4045`
- The ``glue-cache`` *option* has been marked as deprecated. The glue
cache *feature* still works and will be permanently *enabled* in a
future release. :gl:`#2146`
Feature Changes
~~~~~~~~~~~~~~~
- Previously, using ``dig +bufsize=0`` had the side effect of disabling
EDNS, and there was no way to test the remote server's behavior when
it had received a packet with EDNS0 buffer size set to 0. This is no
longer the case; ``dig +bufsize=0`` now sends a DNS message with EDNS
version 0 and buffer size set to 0. To disable EDNS, use ``dig
+noedns``. :gl:`#2054`
Bug Fixes
~~~~~~~~~
- In rare circumstances, :iscman:`named` would exit with an assertion failure
when the number of nodes stored in the red-black tree exceeded the
maximum allowed size of the internal hash table. :gl:`#2104`
- Silence spurious system log messages for an EPROTO(71) error code that
was seen on older operating systems, where unhandled ICMPv6 errors
resulted in a generic protocol error being returned instead of a more
specific error code. :gl:`#1928`
- With query name minimization enabled, :iscman:`named` failed to resolve
``ip6.arpa.`` names that had extra labels to the left of the IPv6
part. For example, when :iscman:`named` attempted query name minimization on
a name like ``A.B.1.2.3.4.(...).ip6.arpa.``, it stopped at the
leftmost IPv6 label, i.e. ``1.2.3.4.(...).ip6.arpa.``, without
considering the extra labels (``A.B``). That caused a query loop when
resolving the name: if :iscman:`named` received NXDOMAIN answers, then the
same query was repeatedly sent until the number of queries sent
reached the value of the ``max-recursion-queries`` configuration
option. :gl:`#1847`
- Parsing of LOC records was made more strict by rejecting a sole period
(``.``) and/or ``m`` as a value. These changes prevent zone files
using such values from being loaded. Handling of negative altitudes
which are not integers was also corrected. :gl:`#2074`
- Several problems found by `OSS-Fuzz`_ were fixed. (None of these are
security issues.) :gl:`!3953` :gl:`!3975`
