* rbt node chains were sized to allow for bitstring labels, so they
had 256 levels; but in the absence of bistrings, 128 is enough.
* dns_byaddr_createptrname() had a redundant options argument,
and a very outdated doc comment.
* A number of comments referred to bitstring labels in a way that is
no longer helpful. (A few informative comments remain.)
Commit b69e783164 changed the scope of the
local 'view' variable in load_configuration(), but the code section
guarded by the #ifdef USE_DNSRPS directive was not adjusted accordingly,
causing build errors for DNSRPS-enabled builds. Fix the latter by
declaring the 'view' variable inside the loop in the DNSRPS-specific
block of code.
If the address lookup of the primary server fails just abort
the current update request rather than calling exit. This allows
nsupdate to cleanup gracefully.
The ADB hashmaps are stored in extra memory contexts, so the hash
tables are excluded from the overmem accounting. The new memory
context was unnamed, give it a proper name.
Same thing has happened with extra memory context used for named
global log context - give the extra memory context a proper name.
Set the DS state after issuing 'rndc dnssec -checkds'. If the DS
was published, it should go in RUMOURED state, regardless whether it
is already safe to do so according to the state machine.
Leaving it in HIDDEN (or if it was magically already in OMNIPRESENT or
UNRETENTIVE) would allow for easy shoot in the foot situations.
Similar, if the DS was withdrawn, the state should be set to
UNRETENTIVE. Leaving it in OMNIPRESENT (or RUMOURED/HIDDEN)
would also allow for easy shoot in the foot situations.
The total memory counter had again little or no meaning when we removed
the internal memory allocator. It was just a monotonic counter that
would count add the allocation sizes but never subtracted anything, so
it would be just a "big number".
The maxinuse memory counter indicated the highest amount of
memory allocated in the past. Checking and updating this high-
water mark value every time memory was allocated had an impact
on server performance, so it has been removed. Memory size can
be monitored more efficiently via an external tool logging RSS.
The malloced and maxmalloced memory counters were mostly useless since
we removed the internal allocator blocks - it would only differ from
inuse by the memory context size itself.
The signal handler in the isc_loop would wait for all the work to finish
before interrupting the signing. Add teardown handlers via
isc_loopmgr_teardown() to signal the assignwork() it should stop signing
and bail-out early.
NOTE: The dnssec-signzone binary still can't be interrupted during zone
loading, zone cleaning, nsec(3) chain generation or zone writing. This
might get addressed in the future if it becomes a problem.
Instead of dumping the signed zone contents node by node during the
signing, dump the entire zone at the end. This was already done for the
raw zone format, but it shows that the IO is better utilized when the
zone dump is done in one single write rather than in small chunks.
A side effect of dumping node by node was that all names were printed
relative to the zone origin rather than being grouped under different
$ORIGINs as would normally be the case when dumping a zone. Also, state
was not maintained from one node to the next regarding whether the CLASS
has already been printed, so it was always included with the first
record of each node.
Since dnssec-signzone uses the dns_master_style_explicittl text format
style, and is the only application that does so, we can revise that
style and add a new DNS_STYLEFLAG_CLASS_PERNAME flag to get the output
back to what it was before this change.
Use isc_job_run() instead of isc_task_send() for dnssec-signzone
worker threads.
Also fix the issue where the additional assignwork() would be run only
from the main thread effectively serializing all the signing.
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.
Change the 'forward' system test to enable DoT on ns2 server,
and test that forwarding from ns4 to the DoT-enabled ns2 works.
In order to test different scenarios, create a test CA (based on
similar CAs for 'doth' and 'nsupdate' system tests), and test
both insecure (no certificate validation) and secure (also with
mutual TLS) TLS configurations, as well as a configuration with an
expired certificate.
Add support for loading and validating the 'tls' parameter from
the forwarders' configuration.
This prepares ground for adding support to forward queries to
DoT-enabled upstream servers.
A 'tls' statement can be specified both for individual addresses
and for the whole list (as a default value when an individual
address doesn't have its own 'tls' set), just as it was done
before for the 'port' value.
Create a new function 'print_rawqstring()' to print a string residing
in a 'isc_textregion_t' type parameter.
Create a new function 'copy_string()' to copy a string from a
'cfg_obj_t' object into a 'isc_textregion_t'.
Return 'isc_result_t' type value instead of 'bool' to indicate
the actual failure. Rename the function to something not suggesting
a boolean type result. Make changes in the places where the API
function is being used to check for the result code instead of
a boolean value.
Add a test case for a server that uses a resolver as an parental-agent.
We need two root servers, ns1 and ns10, one that delegates to the
'checkds' tld with the DS published (ns2), and one that delegates to
the 'checkds' tld with the DS removed (ns5). Both root zones are
being setup in the 'ns1/setup.sh' script.
We also need two resolvers, ns3 and ns8, that use different root hints
(one uses ns1 address as a hint, the other uses ns10).
Then add the checks to test_checkds.py is similar to the existing tests.
Update 'types' because for zones that have the DS withdrawn (or to be
withdrawn), the CDS and CDNSKEY records should not be published and
thus should not be in the NSEC bitmap.
named formerly reserved a set of dispatch objects for use when
sending requests from user-specified source ports. this objects
are no longer used and have been removed.
Add 'port' token to deprecated.conf. Also add options
'use-v4-udp-ports', 'use-v6-udp-ports', 'avoid-v4-udp-ports',
and 'avoid-v6-udp-ports'.
All of these should trigger warnings (except when deprecation warnings
are being ignored).
Deprecate the use of "port" when configuring query-source(-v6),
transfer-source(-v6), notify-source(-v6), parental-source(-v6),
etc. Also deprecate use-{v4,v6}-udp-ports and avoid-{v4,v6}udp-ports.
When we change the view in the view->managed_keys, we never commit the
change, keeping the previous view possibly attached forever.
Call the dns_zone_setviewcommit() immediately after changing the view as
we are detaching the previous view anyway and there's no way to recover
from that.
The condition was accidentally reversed during refactoring in
9730ac4c56 . It would result in skipped
tests on builds with proper support and false negatives on builds
without proper feature support.
Credit for reporting the issue and the fix goes to Stanislav Levin.
Instead of using the current working directory to find the ifconfig.sh
script, look for the ifconfig.sh.in template in the directory where the
testsock.pl script is located. This enables the testsock.pl script to be
called from any working directory.
Using the ifconfig.sh.in template is sufficient, since it contains
the necessary information to be extracted: the max= value (which is
hard-coded in the template).
Move the core dump detection functionality for system test runs into a
separate script. This enables reuse by the pytest runner. The
functionality remains the same.
Avoid creating any temporary files in the current workdir.
Additional/changing files in the bin/tests/system directory are
problematic for pytest/xdist collection phase, which assumes the list of
files doesn't change between the collection phase of the main pytest
thread and the subsequent collection phase of the xdist worker threads.
Since the testcrypto.sh is also called during pytest initialization
through conf.sh.common (to detect feature support), this could
occasionally cause a race condition when the list of files would be
different for the main pytest thread and the xdist worker.
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.
limit the number of simultaneous DNS UPDATE events that can be
processed by adding a quota for update and update forwarding.
this quota currently, arbitrarily, defaults to 100.
also add a statistics counter to record when the update quota
has been exceeded.
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.
Prime the cache with the following records:
shortttl.cname.example. 1 IN CNAME longttl.target.example.
longttl.target.example. 600 IN A 10.53.0.2
Wait for the CNAME record to expire, disable the authoritative server,
and query 'shortttl.cname.example' again, expecting a stale answer.
This bug was masked in the tests because the `catz` test script did an
`rndc addzone` before an `rndc delzone`. The `addzone` autovivified
the NZF config, so `delzone` worked OK.
This commit swaps the order of two sections of the `catz` test script
so that it uses `delzone` before `addzone`, which provokes a crash
when `delzone` requires a non-NULL NZF config.
To fix the crash, we now try to remove the zone from the NZF config
only if it was dynamically added but not by a catalog zone.
Remove parsing the configuration options 'alt-transfer-source',
'alt-transfer-source-v6', and 'use-alt-transfer-source', and remove
the corresponding code that implements the feature.
Use the configured 'source' and 'source-v6' when initiating a zone
transfer, sending a notify, or when checking for the DS. Remove the
special code for using alternate transfer sources.
Update some system tests to use the new configuration and make sure
the tests still work.
Add a new way to configure the preferred source address when talking to
remote servers such as primaries and parental-agents. This will
eventually deprecate options such as 'parental-source',
'parental-source-v6', 'transfer-source', etc.
Example of the new configuration:
parental-agents "parents" port 5353 \
source 10.10.10.10 port 5354 dscp 54 \
source-v6 2001:db8::10 port 5355 dscp 55 {
10.10.10.11;
2001:db8::11;
};
The pre-defined test cases use named.$TESTCASE.conf naming convention,
where TESTCASE is a human readable name contaning actual word(s). The
autogenerated test cases' names always start with a number from 1 to 6.
bin/tests/system/rrsetorder/dig.out* files match a gitignore expression
present in bin/tests/system/.gitignore. Since these are meant to be
reference files that are compared to the files generated when the
"rrsetorder" system test is run, rename them to avoid listing tracked
files in .gitignore files.
Additionally to renaming, it changes the function definition so that
it accepts a pointer to pointer instead of returning a pointer to the
new object.
It is mostly done to make it in line with other functions in the
module.
