Since BIND libraries are no longer considered public and
dns_rdataslab_tordataset() is not used anywhere in the tree, remove the
latter and its associated dns_rdatasetmethods_t callbacks from
lib/dns/rdataslab.c.
Add a function for determining whether the supplied version of a mirror
zone passes DNSSEC validation and is signed using a trusted key. Define
a new libdns result signifying a zone verification failure.
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.
Add a new libdns function, dns_zone_logv(), which takes a single va_list
argument rather than a variable number of arguments and can be used as a
base for implementing more specific zone logging functions.
- Replace external -DOPENSSL/-DPKCS11CRYPTO with properly AC_DEFINEd
HAVE_OPENSSL/HAVE_PKCS11
- Don't enforce the crypto provider from platform.h, just from dst_api.c
and configure scripts
The three functions has been modeled after the arc4random family of
functions, and they will always return random bytes.
The isc_random family of functions internally use these CSPRNG (if available):
1. getrandom() libc call (might be available on Linux and Solaris)
2. SYS_getrandom syscall (might be available on Linux, detected at runtime)
3. arc4random(), arc4random_buf() and arc4random_uniform() (available on BSDs and Mac OS X)
4. crypto library function:
4a. RAND_bytes in case OpenSSL
4b. pkcs_C_GenerateRandom() in case PKCS#11 library
Rename find_zone_keys() to dns__zone_findkeys() and move it to
lib/dns/zone_p.h, so that it can be used in unit tests. Add a comment
describing the purpose of this function.
Rename update_sigs() to dns__zone_updatesigs() and move it to
lib/dns/zone_p.h, so that it can be unit tested. Add a comment
describing the purpose of this function.
Implement a new variant of dns_dt_create() to enable a dnstap
environment structure to hold the task in the context of which
dns_dt_reopen() will be executed.
4798. [func] Keys specified in "managed-keys" statements
are tagged as "initializing" until they have been
updated by a key refresh query. If initialization
fails it will be visible from "rndc secroots".
