This commit disables the unused 'tls' clause options. For these some
backing code exists, but their values are not really used anywhere,
nor there are sufficient syntax tests for them.
These options are only disabled temporarily, until TLS certificate
verification gets implemented.
Use relative names when adding SOA record and a long domain
name to create SOA RR where the wire format is longer than
the initial buffer allocation in dns_sdlz_putrr.
This commit makes the 'doth' system test skip HTTP headers check when
curl version is new enough but was compiled without HTTP/2 support.
This should fix the 'doth' system test for macOS systems using
macports.
The following scenario triggers a "named" crash:
1. Configure a catalog zone.
2. Start "named".
3. Comment out the "catalog-zone" clause.
4. Run `rndc reconfig`.
5. Uncomment the "catalog-zone" clause.
6. Run `rndc reconfig` again.
Implement the required cleanup of the in-memory catalog zone during
the first `rndc reconfig`, so that the second `rndc reconfig` could
find it in an expected state.
the resolver test checks that the correct number of fetches have
been sent NS rrsets of a given size, but it formerly did so by
counting queries received by the authoritative server, which could
result in an off-by-one count if one of the queries had been resent
due to a timeout or a port number collision.
this commit changes the test to count fetches initiated by the
resolver, which should prevent the intermittent test failure, and
is the actual datum we were interested in anyway.
Most of the test zones in the dnssec system test can be verified.
Use -z when only a single key is being used so that the verifier
knows that only a single key is in use.
The method used to generate a test zone with multiple NSEC and
NSEC3 chains was incorrect. Multiple calls to dnssec-signzone
with multiple parameters is not additive. Extract the chain on
each run then add them to the final signed zone instance.
This is almost minimal prototype to show how to use python-hypothesis
library in a system test. It does not fully replace existing shell-based
system test for wildcards.
The version number for the XML statistics channel was not incremented
correctly after removal of isc_socket code in
a55589f881, and the JSON version number
was not incremented at all.
Check to see whether there are outstanding requests in the
httpd receive buffer after sending the response, and if so,
process them.
Test that pipelined requests are handled by sending multiple
minimal HTTP/1.1 using netcat (nc) and checking that we get
back the same number of responses.
In the 9.17.19 release "tls" statements verification code was
added. The code was too strict and assumed that every such a statement
should have both "cert-file" and "key-file" specified. This turned out
to be a regression, as in some cases we plan to use the "tls"
statement to specify TLS connection parameters.
This commit fixes this behaviour; now a "tls" statement should either
have both "cert-file" and "key-file" specified, or both should be
omitted.
The lame-ttl cache is implemented in ADB as per-server locked
linked-list "indexed" with <qname,qtype>. This list has to be walked
every time there's a new query or new record added into the lame cache.
Determined attacker can use this to degrade performance of the resolver.
Resolver testing has shown that disabling the lame cache has little
impact on the resolver performance and it's a minimal viable defense
against this kind of attack.
Duplicate catalog zone entries caused an assertion failure
in named during configuration. This is now a soft error
that is detected earlier by named and also by named-checkconf.
Update the nsec3 system tests to use the new default values. Change
the policy for "nsec3-other" so that we still have a test case for
non-zero salt length.
Depending upon when the directory is sampled there may be 2
(oldest version removed and rename / reopen is in progresss) or
3 old versions of the log file.
Add a lame delegation to lame.example.org with only an A record
in the additional section; on failure, this will trigger a retry
with AAAA, which will loop. Test that dig returns SERVFAIL, in
addition to confirming that named doesn't hang on shutdown.
The qmin system test was printing spurious output. On investigation,
the test case turned out to be both broken and ineffective: its
expectations were wrong, and it was printing the output because its
wrong expectations were not met, and those failed expectations were
not causing a test failure. All of this has been corrected.
The statistics system test sometimes needs a pause to wait for the
expected stats to be reported.
Also, the test for priming queries was ineffective; the result of
the grep was not being checked.
The catz system test included a test case that was looking for a single
answer record after an update, when it should have been looking for two.
The test usually passed because of timing - the first dig usually got a
response before the update was completed - but occasionally the update
processed fast enough for the test to fail. On investigation, it turned
out to be the test that was wrong.
The digdelv system test has a test case in which stderr was
included in the dig output. When trace logging was in use,
this confused the grep and caused a spurious test failure.
Some of the libns unit tests override the isc_nmhandle_attach() and
_detach() functions. This causes a failure in ns_interface_create()
if a route socket is being used, so we add a parameter to disable it.
Update the 'catz' system test by adding tests that update an
catalog zone (catalog1.example) while preserving existing entries
(increase SOA serial) then check that catalog zone has transferred
and that the existing entries have not accidentally been removed
as a consequence (can return updated zone content).
The new rules compare the target name in PTR and SRV records against
the machine name embedded in the kerberos principal. This can be
used to further restrict what PTR and SRV records can be added or
deleted via dynamic updates if desired.
pytest was failing because it was testing features that had
not been configured. test to see if those features have been
configured before running the tests.
due to comparing logfile suffixes as 32 bit rather than 64 bit
integers, logfiles with timestamp suffixes that should have been
removed when rolling could be left in place. this has been fixed.
the logfileconfig system test did not conform to the style of
other tests, and was difficult to read and maintain. it has
been cleaned up and simplifeid in several ways:
- named.args used when appropriate so that named can be started with
specified command line arguments, instead of having it launched
directly from tests.sh
- unused root zone removed from named configuration
- an existing directory used instead of using 'mkdir' to create one
- dnssec-validation disabled to stop the server sending unnecessary queries
incidental fix: removed leftover debugging printfs from logconf.c.
Unify the header guard style and replace the inconsistent include guards
with #pragma once.
The #pragma once is widely and very well supported in all compilers that
BIND 9 supports, and #pragma once was already in use in several new or
refactored headers.
Using simpler method will also allow us to automate header guard checks
as this is simpler to programatically check.
For reference, here are the reasons for the change taken from
Wikipedia[1]:
> In the C and C++ programming languages, #pragma once is a non-standard
> but widely supported preprocessor directive designed to cause the
> current source file to be included only once in a single compilation.
>
> Thus, #pragma once serves the same purpose as include guards, but with
> several advantages, including: less code, avoidance of name clashes,
> and sometimes improvement in compilation speed. On the other hand,
> #pragma once is not necessarily available in all compilers and its
> implementation is tricky and might not always be reliable.

With isc_mem_get() and dns_name_dup() no longer being able to fail, some
functions can now only return ISC_R_SUCCESS. Change the return type to
void for the following function(s):
* dns_zone_setprimaries()
* dns_zone_setparentals()
* dns_zone_setparentals()
* dns_zone_setalsonotify()
