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)
The old name "common" clashes with the convention of system test
directory naming. It appears as a system test directory, but it only
contains helper files.
To reduce confusion and to allow automatic detection of issues with
possibly missing test files, rename the helper directory to "_common".
The leading underscore indicates the directory is different and the its
name can no longer be confused with regular system test directories.
Add an option to enable/disable inline-signing inside the
dnssec-policy clause. The existing inline-signing option that is
set in the zone clause takes priority, but if it is omitted, then the
value that is set in dnssec-policy is taken.
The built-in policies use inline-signing.
This means that if you want to use the default policy without
inline-signing you either have to set it explicitly in the zone
clause:
zone "example" {
...
dnssec-policy default;
inline-signing no;
};
Or create a new policy, only overriding the inline-signing option:
dnssec-policy "default-dynamic" {
inline-signing no;
};
zone "example" {
...
dnssec-policy default-dynamic;
};
This also means that if you are going insecure with a dynamic zone,
the built-in "insecure" policy needs to be accompanied with
"inline-signing no;".
The changes were mostly done with sed:
find . -name '*.sh' | xargs sed -i 's/`\([^`]*\)`/$(\1)/g'
There have been a few manual changes where the regex wasn't sufficient
(e.g. backslashes inside the `...`) or wrong (`...` referring to docs or
in comments).
Ensure all shell system tests are executed with the errexit option set.
This prevents unchecked return codes from commands in the test from
interfering with the tests, since any failures need to be handled
explicitly.
tsig-keygen generates key files that are different to those that
where generated by dnssec-keygen. Check that nsupdate can still
read those old format files.
the default value of dnssec-validation is 'auto', which causes
a server to send a key refresh query to the root zone when starting
up. this is undesirable behavior in system tests, so this commit
sets dnssec-validation to either 'yes' or 'no' in all tests where
it had not previously been set.
this change had the mostly-harmless side effect of changing the cached
trust level of unvalidated answer data from 'answer' to 'authanswer',
which caused a few test cases in which dumped cache data was examined in
the serve-stale system test to fail. those test cases have now been
updated to expect 'authanswer'.
In order to run the shell system tests, the pytest runner has to pick
them up somehow. Adding an extra python file with a single function
for the shell tests for each system test proved to be the most
compatible way of running the shell tests across older pytest/xdist
versions.
Modify the legacy run.sh script to ignore these pytest-runner specific
glue files when executing tests written in pytest.
* nsupdate should take 12 seconds (one try and three retries with
3 second timeout for each), UDP mode
* nsupdate -u 4 -r 1 should take 8 seconds (one try and one retry with
4 second timeout for each), UDP mode
* nsupdate -u 0 -t 8 -r 1 should also take 8 seconds, UDP mode
* nsupdate -u 4 -t 30 -r 1 should also take 8 seconds, as -u takes
precedence over -t, UDP mode
* nsupdate -t 8 -v should also take 8 seconds, TCP mode
Include MD5 feature detection in featuretest tool and use it in some
places. When RHEL distribution or Fedora ELN is in FIPS mode, then MD5
algorithm is unavailable completely and even hmac-md5 algorithm usage
will always fail. Work that around by checking MD5 works and if not,
skipping its usage.
Those changes were dragged as downstream patch bind-9.11-fips-tests.patch
in Fedora and RHEL.
the nsupdate system test was intermittently failing due to the update
quota not being exceeded when it should have been. this is most likely
a timing issue: the client is sending updates too slowly, or the server
is processing them too quickly, for the quota to fill. this commit
attempts to make that the failure less likely by increasing the number
of update transactions from 10 to 20.
The validity default days value of 1 was used for debugging and
left as such accidentally.
Use 10950 days, as used elsewhere (for example, in doth test CA).
This does not affect anything, the value will be effective when
generating new test certificates in the future.
verify that updates are refused when the client is disallowed by
allow-query, and update forwarding is refused when the client is
is disallowed by update-forwarding.
verify that "too many DNS UPDATEs" appears in the log file when too
many simultaneous updates are processing.
DSCP has not been fully working since the network manager was
introduced in 9.16, and has been completely broken since 9.18.
This seems to have caused very few difficulties for anyone,
so we have now marked it as obsolete and removed the
implementation.
To ensure that old config files don't fail, the code to parse
dscp key-value pairs is still present, but a warning is logged
that the feature is obsolete and should not be used. Nothing is
done with configured values, and there is no longer any
range checking.
The system test should never attempt to start or stop any other server
than those that belong to that system test. Therefore, it is not
necessary to specify the system test name in function calls.
Additionally, this makes it possible to run the test inside a
differently named directory, as its name is automatically detected with
the $SYSTESTDIR variable. This enables running the system tests inside a
temporary directory.
Direct use of stop.pl was replaced with a more systematic approach to
use stop_servers helper function.
Remove test cases that rely upon key and denial of existence
management operations triggered by dynamic updates.
The autosign system test needed a bit more care than just removing
because the test cases are dependent on each other, so there are some
additional tweaks such as setting the NSEC3PARAM via rndc signing,
and renaming zone input files. In the process, some additional
debug output files have been added, and a 'ret' fail case overwrite
was fixed.
The checkbashisms script reports errors like this one:
script util/check-line-length.sh does not appear to have a #! interpreter line;
you may get strange results
Checks that malformed _dns SVCB records are rejected unless
check-svcb is set to no, in which case they are accepted. Both
missing ALPN and missing DOHPATH are checked for.
Add a simple test PKI based on the existing one in the doth test.
Check ephemeral, forward-secrecy, and forward-secrecy-mutual-tls
TLS configurations with different scenarios.
Ensure the update zone name is mentioned in the NOTAUTH error message
in the server log, so that it is easier to track down problematic
update clients. There are two cases: either the update zone is
unrelated to any of the server's zones (previously no zone was
mentioned); or the update zone is a subdomain of one or more of the
server's zones (previously the name of the irrelevant parent zone was
misleadingly logged).
Closes#3209
- Removed all code that only runs under CYGWIN, and made all
code that doesn't run under CYGWIN non-optional.
- Removed the $TP variable which was used to add optional
trailing dots to filenames; they're no longer optional.
- Removed references to pssuspend and dos2unix.
- No need to use environment variables for diff and kill.
- Removed uses of "tr -d '\r'"; this was a workaround for
a cygwin regex bug that is no longer needed.
This commit converts the license handling to adhere to the REUSE
specification. It specifically:
1. Adds used licnses to LICENSES/ directory
2. Add "isc" template for adding the copyright boilerplate
3. Changes all source files to include copyright and SPDX license
header, this includes all the C sources, documentation, zone files,
configuration files. There are notes in the doc/dev/copyrights file
on how to add correct headers to the new files.
4. Handle the rest that can't be modified via .reuse/dep5 file. The
binary (or otherwise unmodifiable) files could have license places
next to them in <foo>.license file, but this would lead to cluttered
repository and most of the files handled in the .reuse/dep5 file are
system test files.
Replace most "master/slave" terminology in tests with the preferred
"primary/secondary", with the following exceptions:
- When testing the old syntax
- When master is used in master file and master file format terms
- When master is used in hostmaster or postmaster terms
- When master used in legacy domain names (for example in dig.batch)
- When there is no replacement (for example default-masters)
Add tests to the nsupdate system test to make sure that CDS and/or
CDNSKEY that match an algorithm in the DNSKEY RRset are allowed. Also
add tests that updates are rejected if the algorithm does not match.
Remove the now redundant test cases from the dnssec system test.
Update the checkzone system test: Change the algorithm of the CDS and
CDNSKEY records so that the zone is still rejected.
The ISC_MEM_DEBUGSIZE and ISC_MEM_DEBUGCTX did sanity checks on matching
size and memory context on the memory returned to the allocator. Those
will no longer needed when most of the allocator will be replaced with
jemalloc.
