The old-style DLZ drivers were already marked as no longer actively
maintained and expected to be removed eventually. With the new automake
build system, the old-style DLZ drivers were not updated, and instead of
putting an effort into something that's not being maintained, let's
rather remove the unmaintained code.
Closes: #2814
The map masterfile-format is very fragile and it needs API bump every
time a RBTDB data structures changes. Also while testing it, we found
out that files larger than 2GB weren't loading and nobody noticed, and
loading many map files were also failing (subject to kernel limits).
Thus we are marking the masterfile-format type 'map' as deprecated and
to be removed in the next stable BIND 9 release.
"cache-file" was already documented as intended for testing
purposes only and not to be used, so we can remove it without
waiting. this commit marks the option as "ancient", and
removes all the documentation and implementing code, including
dns_cache_setfilename() and dns_cache_dump().
it also removes the documentation for the '-x cachefile`
parameter to named, which had already been removed, but the man
page was not updated at the time.

- when transfer-source(-v6), query-source(-v6), notify-source(-v6)
or parental-source(-v6) are specified with a port number, issue a
warning.
- when the port specified is the same as the DNS listener port (i.e.,
53, or whatever was specified as "port" in "options"), issue a fatal
error.
- check that "port" is in range. (previously this was only checked
by named, not by named-checkconf.)
- added checkconf tests.
- incidental fix: removed dead code in check.c:bind9_check_namedconf().
(note: if the DNS port is specified on the command line with "named -p",
that is not conveyed to libbind9, so these checks will not take it into
account.)
The ns3->ns2 forwarding is now done using the IPv6 addresses, so we also
test that the query-source-v6 address is still operational after removal
of interface adjustment.
Previously, named would run with a configuration
where *-source-v6 (notify-source-v6, transfer-source-v6 and
query-source-v6) address and port could be simultaneously used for
listening. This is no longer true for BIND 9.16+ and the code that
would do interface adjustments would unexpectedly disable listening on
TCP for such interfaces.
This commit removes the code that would adjust listening interfaces
for addresses/ports configured in *-source-v6 option.
The native PKCS#11 support has been removed in favour of better
maintained, more performance and easier to use OpenSSL PKCS#11 engine
from the OpenSC project.
when "checking lame server clients are dropped below the hard limit",
periodically a query is sent for a name for which the server is
authoritative, to verify that legitimate queries can still be
processed while the server is dealing with a flood of lame delegation
queries. those queries used the same dig options as elsewhere in the
fetchlimit test, including "+tries=1 +timeout=1". on slow systems, a
1-second timeout may be insufficient to get an answer even if the server
is behaving well. this commit increases the timeout for the check
queries to 2 seconds in hopes that will be enough to eliminate test
failures in CI.
This commit modifies the MTU of the loopback interface on
Linux systems to 1500, so that oversized UDP packets can
trigger EMSGSIZE errors, and tests that named handles
such errors correctly.
Note that the loopback MTU size has not yet been modified
for other platforms.
This commit ensures that DoH (and DoT) functionality works well via
IPv6 as well.
The changes were made because it turned out that dig could not make
DoH queries against an IPv6 IP address. These tests ensure that such a
bug will not remain unnoticed.
The commit also increases the servers' startup timeout to 25 seconds
because the initial timeout of 14 seconds was too short to generate
(!) eight 4096 bit ephemeral RSA certificates on a heavily loaded CI
runner in some pipeline runs.
This commit replaces ad-hoc code for DoH connect URI construction with
isc_nm_http_makeuri(), making it handle IPv6 adresses properly (among
other things).
This commit adds new function isc_nm_http_makeuri() which is supposed
to unify DoH URI construction throughout the codebase.
It handles IPv6 addresses, hostnames, and IPv6 addresses given as
hostnames properly, and replaces similar ad-hoc code in the codebase.
- removed unused functions
- changed some public functions to static that are never called
from outside client.c
- removed unused types and function prototypes
- renamed dns_client_destroy() to dns_client_detach()
The previous versions of BIND 9 exported its internal libraries so that
they can be used by third-party applications more easily. Certain
library functions were altered from specific BIND-only behavior to more
generic behavior when used by other applications.
This commit removes the function isc_lib_register() that was used by
external applications to enable the functionality.
test server now has tcp-idle-timeout set to 5 seconds and
tcp-keepalive-timeout set to 7, so queries that follow a 6-second sleep
should either succeed or fail depending on whether the keepalive option
was sent.
Add a statschannel test case to confirm that when keys are removed
(in this case because of a dnssec-policy change), the corresponding
dnssec-sign stats are cleared and are no longer shown in the
statistics.
Add a test case that has more than four keys (the initial number of
key slots that are created for dnssec-sign statistics). We shouldn't
be expecting weird values.
This fixes some errors in the manykeys zone configuration (keys
were created for algorithm RSASHA256, but the policy expected RSASHA1,
and the zone was not allowing dynamic updates).
This also fixes an error in the calls to 'zones-json.pl': The perl
script excepts an index number where the zone can be found, rather
than the zone name.
Add a test case for migrating CSK to dnssec-policy. The keymgr has no
way of telling that the key is used as a CSK, but if there is only one
key to migrate it is going to assume it must be a CSK.
Previously, when dnssec-cds copied CDS records to make DS records,
its -a algorithm option did not have any effect. This means that if
the child zone is signed with older software that generates SHA-1 CDS
records, dnssec-cds would (by default) create SHA-1 DS records in
violation of RFC 8624.
This change makes the dnssec-cds -a option apply to CDS records as
well as CDNSKEY records. In the CDS case, the -a algorithms are the
acceptable subset of possible CDS algorithms. If none of the CDS
records are acceptable, dnssec-cds tries to generate DS records from
CDNSKEY records.
The additional processing method has been expanded to take the
owner name of the record, as HTTPS and SVBC need it to process "."
in service form.
The additional section callback can now return the RRset that was
added. We use this when adding CNAMEs. Previously, the recursion
would stop if it detected that a record you added already exists. With
CNAMEs this rule doesn't work, as you ultimately care about the RRset
at the target of the CNAME and not the presence of the CNAME itself.
Returning the record allows the caller to restart with the target
name. As CNAMEs can form loops, loop protection was added.
As HTTPS and SVBC can produce infinite chains, we prevent this by
tracking recursion depth and stopping if we go too deep.
