Remove another remnant of shared secret HMAC-MD5 support.
Explain that with currently recommended setups DNSKEY records are
inserted automatically, but you can still use $INCLUDE in other cases.
Use them in structs for various rdata types where they are missing.
This doesn't change the structs since we are replacing explicit
uint8_t field types with aliases for uint8_t.
Use dns_dsdigest_t in library function arguments.
Improve dnssec-cds with these more specific types.
Alphabetize options and synopsis; remove spurious -z from synopsis;
remove remnants of deprecated -k option; remove mention of long-gone
TSIG support; refer to -T KEY in options that are only relevant to
pre-RFC3755 DNSSEC; remove unnecessary -n ZONE from the example, and
add a -f KSK example.
* Alphabetize the option lists in the man page and help text
* Make the synopses more consistent between the man page and help
text, in particular the number of different modes
* Group mutually exclusive options in the man page synopses, and order
options so that it is more clear which are available in every mode
* Expand the DESCRIPTION to provide an overview of the output modes
and input modes
* Improve cross-references between options
* Leave RFC citations to the SEE ALSO section, and clarify which RFC
specifies what
* Clarify list of digest algorithms in dnssec-dsfromkey and dnssec-cds
man pages
We can remove this, because it is used in `strtodsdigest` but that
already no longer covers the algorithm name "GOST".
There is one more GOST reference in `bin/python/isc/checkds.py.in`
but that is used for presentation format and probably should stay.

Make will choose modified manual from build directory or original from source
directory automagically. Take advantage of install tool feature.
Install all files in single command instead of iterating on each of them.
Extend check_dnskey_sigs() so that, if requested, it checks whether the
DNSKEY RRset at zone apex is signed by at least one trust anchor. The
trust anchor table is passed as an argument to dns_zoneverify_dnssec()
and passed around in the verification context structure. Neither
dnssec-signzone nor dnssec-verify are yet modified to make use of that
feature, though.
Since exit() is no longer called upon any dns_zoneverify_dnssec() error,
verification failures should be signalled to callers. Make
dns_zoneverify_dnssec() return an isc_result_t and handle both success
and error appropriately in bin/dnssec/dnssec-signzone.c and
bin/dnssec/dnssec-verify.c. This enables memory leak detection during
shutdown of these tools and causes dnssec-signzone to print signing
statistics even when zone verification fails.
These functions will be used in the process of replacing fatal(),
check_result(), and fprintf() calls throughout lib/dns/zoneverify.c with
code that does not call exit(). They are intended for:
- zoneverify_log_error(): logging problems encountered while
performing zone verification,
- zoneverify_print(): printing status messages and reports which are
only useful in standalone tools.
To make using dns_zone_logv() possible, add a new "zone" argument to
dns_zoneverify_dnssec() that standalone tools are expected to set to
NULL.
This commit only moves code around, with the following exceptions:
- the check_dns_dbiterator_current() macro and functions
is_delegation() and has_dname() were removed from
bin/dnssec/dnssectool.{c,h} and duplicated in two locations:
bin/dnssec/dnssec-signzone.c and lib/dns/zoneverify.c; these
functions are used both by the code in bin/dnssec/dnssec-signzone.c
and verifyzone(), but are not a good fit for being exported by a
code module responsible for zone verification,
- fatal() and check_result() were duplicated in lib/dns/zoneverify.c
as static functions which do not use the "program" variable any more
(as it is only set by the tools in bin/dnssec/); this is a temporary
step which only aims to prevent compilation from breaking - these
duplicate functions will be removed once lib/dns/zoneverify.c is
refactored not to use them,
- the list of header files included by lib/dns/zoneverify.c was
expanded to encompass all header files that are actually used by the
code in that file,
- a description of the purpose of the commented out "fields" inside
struct nsec3_chain_fixed was added.
DNAME records indicate bottom of zone and thus no records below a DNAME
should be DNSSEC-signed or included in NSEC(3) chains. Add a helper
function, has_dname(), for detecting DNAME records at a given node.
Prevent signing DNAME-obscured records. Check that DNAME-obscured
records are not signed.
