The $SYSTEMTESTTOP shell variable if often set to .. in various shell
scripts inside bin/tests/system/, but most of the time it is only
used one line later, while sourcing conf.sh. This hardly improves
code readability.
$SYSTEMTESTTOP is also used for the purpose of referencing
scripts/files living in bin/tests/system/, but given that the
variable is always set to a short, relative path, we can drop it and
replace all of its occurrences with the relative path without adversely
affecting code readability.
this changes most visble uses of master/slave terminology in tests.sh
and most uses of 'type master' or 'type slave' in named.conf files.
files in the checkconf test were not updated in order to confirm that
the old syntax still works. rpzrecurse was also left mostly unchanged
to avoid interference with DNSRPS.
as "type primary" is preferred over "type master" now, it makes
sense to make "primaries" available as a synonym too.
added a correctness check to ensure "primaries" and "masters"
cannot both be used in the same zone.
The rewrite of BIND 9 build system is a large work and cannot be reasonable
split into separate merge requests. Addition of the automake has a positive
effect on the readability and maintainability of the build system as it is more
declarative, it allows conditional and we are able to drop all of the custom
make code that BIND 9 developed over the years to overcome the deficiencies of
autoconf + custom Makefile.in files.
This squashed commit contains following changes:
- conversion (or rather fresh rewrite) of all Makefile.in files to Makefile.am
by using automake
- the libtool is now properly integrated with automake (the way we used it
was rather hackish as the only official way how to use libtool is via
automake
- the dynamic module loading was rewritten from a custom patchwork to libtool's
libltdl (which includes the patchwork to support module loading on different
systems internally)
- conversion of the unit test executor from kyua to automake parallel driver
- conversion of the system test executor from custom make/shell to automake
parallel driver
- The GSSAPI has been refactored, the custom SPNEGO on the basis that
all major KRB5/GSSAPI (mit-krb5, heimdal and Windows) implementations
support SPNEGO mechanism.
- The various defunct tests from bin/tests have been removed:
bin/tests/optional and bin/tests/pkcs11
- The text files generated from the MD files have been removed, the
MarkDown has been designed to be readable by both humans and computers
- The xsl header is now generated by a simple sed command instead of
perl helper
- The <irs/platform.h> header has been removed
- cleanups of configure.ac script to make it more simpler, addition of multiple
macros (there's still work to be done though)
- the tarball can now be prepared with `make dist`
- the system tests are partially able to run in oot build
Here's a list of unfinished work that needs to be completed in subsequent merge
requests:
- `make distcheck` doesn't yet work (because of system tests oot run is not yet
finished)
- documentation is not yet built, there's a different merge request with docbook
to sphinx-build rst conversion that needs to be rebased and adapted on top of
the automake
- msvc build is non functional yet and we need to decide whether we will just
cross-compile bind9 using mingw-w64 or fix the msvc build
- contributed dlz modules are not included neither in the autoconf nor automake
The autosign test has a test case where a DNSSEC maintaiend zone
has a set of DNSSEC keys without any timing metadata set. It
tests if named picks up the key for publication and signing if a
delayed dnssec-settime/loadkeys event has occured.
The test failed intermittently despite the fact it sleeps for 5
seconds but the triggered key reconfigure action should happen after
3 seconds.
However, the test output showed that the test query came in before
the key reconfigure action was complete (see excerpts below).
The loadkeys command is received:
15:38:36 received control channel command 'loadkeys delay.example.'
The reconfiguring zone keys action is triggered after 3 seconds:
15:38:39 zone delay.example/IN: reconfiguring zone keys
15:38:39 DNSKEY delay.example/NSEC3RSASHA1/7484 (ZSK) is now published
15:38:39 DNSKEY delay.example/NSEC3RSASHA1/7455 (KSK) is now published
15:38:39 writing to journal
Two seconds later the test query comes in:
15:38:41 client @0x7f1b8c0562b0 10.53.0.1#44177: query
15:38:41 client @0x7f1b8c0562b0 10.53.0.1#44177: endrequest
And 6 more seconds later the reconfigure keys action is complete:
15:38:47 zone delay.example/IN: next key event: 05-Dec-2019 15:48:39
This commit fixes the test by checking the "next key event" log has
been seen before executing the test query, making sure that the
reconfigure keys action has been complete.
This commit however does not fix, nor explain why it took such a long
time (8 seconds) to reconfigure the keys.
The first step in all existing setup.sh scripts is to call clean.sh. To
reduce code duplication and ensure all system tests added in the future
behave consistently with existing ones, invoke clean.sh from run.sh
before calling setup.sh.
The oldsigs test was checking only for the validity of the A
a.oldsigs.example. resource record and associated DNSSEC signature while
the zone might not have been fully signed yet leading to validation
failures because of bogus signatures on the validation path.
This commit changes the test to test that all old signatures in the
oldsigs.example. zone were replaced and the zone is fully resigned
before running the main check.
this adds functions in conf.sh.common to create DS-style trust anchor
files. those functions are then used to create nearly all of the trust
anchors in the system tests.
there are a few exceptions:
- some tests in dnssec and mkeys rely on detection of unsupported
algorithms, which only works with key-style trust anchors, so those
are used for those tests in particular.
- the mirror test had a problem with the use of a CSK without a
SEP bit, which still needs addressing
in the future, some of these tests should be changed back to using
traditional trust anchors, so that both types will be exercised going
forward.
the current method used for testing distribution of signatures
is failure-prone. we need to replace it with something both
effective and portable, but in the meantime we're commenting
out the jitter test.
The BusyBox version of awk treats some variables which other awk
implementations consider to be decimal values as octal values. This
intermittently breaks key event interval calculations in the "autosign"
system test, trigger false positives for it. Prevent the problem from
happening by stripping leading zeros from the affected awk variables.
When trying to extract the key ID from a key file name, some test code
incorrectly attempts to strip all leading zeros. This breaks tests when
keys with ID 0 are generated. Add a new helper shell function,
keyfile_to_key_id(), which properly handles keys with ID 0 and use it in
test code whenever a key ID needs to be extracted from a key file name.
When a zone is converted from NSEC to NSEC3, the private record at zone
apex indicating that NSEC3 chain creation is in progress may be removed
during a different (later) zone_nsec3chain() call than the one which
adds the NSEC3PARAM record. The "delzsk.example" zone check only waits
for the NSEC3PARAM record to start appearing in dig output while private
records at zone apex directly affect "rndc signing -list" output. This
may trigger false positives for the "autosign" system test as the output
of the "rndc signing -list" command used for checking ZSK deletion
progress may contain extra lines which are not accounted for. Ensure
the private record is removed from zone apex before triggering ZSK
deletion in the aforementioned check.
Also future-proof the ZSK deletion progress check by making it only look
at lines it should care about.
For all system tests utilizing named instances, call clean.sh from each
test's setup.sh script in a consistent way to make sure running the same
system test multiple times using run.sh does not trigger false positives
caused by stale files created by previous runs.
Ideally we would just call clean.sh from run.sh, but that would break
some quirky system tests like "rpz" or "rpzrecurse" and being consistent
for the time being does not hurt.
Reduce code duplication by replacing a code snippet repeated throughout
system tests using "trusted-keys" and/or "managed-keys" configuration
sections with calls to keyfile_to_{managed,trusted}_keys() helper
functions.
- all tests with "recursion yes" now also specify "dnssec-validation yes",
and all tests with "recursion no" also specify "dnssec-validation no".
this must be maintained in all new tests, or else validation will fail
when we use local root zones for testing.
- clean.sh has been modified where necessary to remove managed-keys.bind
and viewname.mkeys files.
- removed a few remaing places where output wasn't being passed
through echo_i or cat_i
- added a "digcomp" function to conf.sh.in to send digcomp.pl output
through cat_i and return the correct exit value
- set SYSTESTDIR when calling echo_i from nsX directories, so that
the test name will always be printed correctly
- fixed a test name typo in conf.sh.in
