these options control default timing of retries in the resolver
for experimental purposes; they are not known to useful in production
environments. they will be removed in the future; for now, we
only log a warning if they are used.
This commit extends the 'doth' system tests with additional secondary
NS instance that reuses the same 'tls' entry for connecting the the
primary to download zones. This configurations were known to crash
secondaries in some cases.
This commit adds a system test suite for PROXYv2. The idea on which it
is based is simple:
1. Firstly we check that 'allow-proxy' and 'allow-proxy-on' (whatever
is using the new 'isc_nmhandle_real_localaddr/peeraddr()') do what
they intended to do.
2. Anything else that needs an interface or peer address (ACL
functionality, for example) is using the old
'isc_nmhandle_localaddr/peeraddr()' - which are now returning
addresses received via PROXY (if any) instead of the real connection
addresses. The beauty of it that we DO NOT need to verify every bit of
the code relying on these functions: whatever works in one place will
work everywhere else, as these were the only functions that allowed
any higher level code to get peer and interface addresses.
This way it is relatively easy to see if PROXYv2 works as intended.
The system tests need to be updated because non-zero iterations are no
longer accepted.
The autosign system test changes its iterations from 1 to 0 in one
test case. This requires the hash to be updated.
The checkconf system test needs to change the iterations in the good
configuration files to 0, and in the bad ones to 1 (any non-zero value
would suffice, but we test the corner case here). Also, the expected
failure message is change, so needs to be adjusted.
The nsec3 system test also needs iteration configuration adjustments.
In addition, the test script no longer needs the ITERATIONS environment
variable.
In the process of updating the system tests, I noticed an error
in the dnssec-policy "nsec3-other", where the salt length in one
configuration file is different than in the other (they need to be
the same). Furthermore, the 'rndc signing -nsec3param' test case
is operated on the zone 'nsec-change.kasp', so is moved so that the
tests on the same zone are grouped together.
Create a utility package for code shared by the python tests. The
utility functions should use reasonable defaults and be split up into
modules according to their functionality.
Ensure assert rewriting is enabled for the modules to get the most
useful output from pytest.
By default, the useful assertion message rewrite is used by pytest for
test modules only. Since another module is imported with shared
functionality, ensure it has pytest's assertion message rewriting
enabled to obtain more debug information in case it fails.
This file is executed outside of pytest with pure python, which doesn't
do any AssertionError message rewriting like pytest. Ensure the assert
messages in this file provide a useful debug message.
Rewrite and reorganize the test documentation to focus on the pytest
runner, omit any mentions of the legacy runner which are no longer
relevant, and mention a few pytest tricks.
The ns2/named-alt3.conf.in config file was removed in
f8e264ba6d. From then on, system test
reports:
sed: can't read ns2/named-alt3.conf.in: No such file or directory"
Drop the last remnant of ns2/named-alt3.conf.in.
when transferring in a non-inline-signing secondary for the first time,
we previously never set the value of zone->loadtime, so it remained
zero. this caused a test failure in the statschannel system test,
and that test case was temporarily disabled. the value is now set
correctly and the test case has been reinstated.
The AES algorithm for DNS cookies was being kept for legacy reasons, and
it can be safely removed in the next major release. Remove both the AES
usage for DNS cookies and the AES implementation itself.
Not every element tagged `skipped` in the JUnitXML tree has to contain
the `type` attribute. An example of that is a test that results in
xpass.
This has been verified with pytest version 7.4.2 and prior.
Add a test case where serve-stale is enabled on a server that also
servers a local authoritative zone.
The particular case tests a lame delegation and checks if falling
back to serving stale data does not attempt to retrieve the query
by recursing from the root down.
The lock-file configuration (both from configuration file and -X
argument to named) has better alternatives nowadays. Modern process
supervisor should be used to ensure that a single named process is
running on a given configuration.
Alternatively, it's possible to wrap the named with flock(1).
All changes in this commit were automated using the command:
shfmt -w -i 2 -ci -bn . $(find . -name "*.sh.in")
By default, only *.sh and files without extension are checked, so
*.sh.in files have to be added additionally. (See mvdan/sh#944)
When named fails to starts due to not being able to obtain
a lock on the lock file that lock file should remain. Check
that the lock file exists before and after the attempt to
start a second instance of named.
We test EDNS requests returning FORMERR where named is expected
to retry without EDNS.
We test EDNS requests returning NOTIMP where named is expected
to fail the transfer as the remote end is not protocol compliant.
The server is expected to retry the transfer using SOA and if
the returned serial is greater than the current serial AXFR.
Check the log that IXFR is request.
Now that inline-signing is ignored when there is no dnssec-policy,
add 'dnssec-policy default;' to the zones when attempting to add them
via 'rndc addzone'.
The 'dynamic-signed-inline-signing.kasp' zone was set up with
the environment variable 'ksktimes', but that should be 'csktimes'
which is set one line above. Since the values are currently the same
the behavior is identical, but of course it should use the correct
variable.
The 'step4.enable-dnssec.autosign' zone was set up twice. This is
unnecessary.
Add a test scenario for a dynamic zone that uses inline-signing which
accidentally has signed the raw version of the zone.
This should not trigger resign scheduling on the raw version of the
zone.
The usage of the newline in the replacement part of the 'sed' call
works in GNU systems, but not in OpenBSD. Use 'awk' instead.
Also use the extended syntax of regular expressions for 'grep', which
is similarly more portable across the supported systems.
'rndc thaw' initiates asynchrous loading of all the zones
similar to 'rndc load'. Wait for the test zone's load to
complete before testing that it is updatable again.
Instead of creating new memory pools for each new dns_message, change
dns_message_create() method to optionally accept externally created
dns_fixedname_t and dns_rdataset_t memory pools. This allows us to
preallocate the memory pools in ns_client and dns_resolver units for the
lifetime of dns_resolver_t and ns_clientmgr_t.
The XFRST_INITIALSOA state in the xfrin module is named like that,
because the first RR in a zone transfer must be SOA. However, the
name of the state is a bit confusing (especially when exposed to
the users with statistics channel), because it can be mistaken with
the refresh SOA request step, which takes place before the zone
transfer starts.
Rename the state to XFRST_ZONEXFRREQUEST (i.e. Zone Transfer Request).
During that step the state machine performs several operations -
establishing a connection, sending a request, and receiving/parsing
the first RR in the answer.
Add two more secondary zones to ns3 to be transferred from ns1,
using its IPv6 address for which the 'tcp-only' is set to 'yes'.
Check the statistics channel's incoming zone transfers information
to confirm that the expected transports were used for each of the
SOA query cases (UDP, TCP, TLS), and also for zone transfers (TCP,
TLS).
