FALLTHOUGH is a copy of how it is defined in <isc/util.h>
UNREACHABLE follows the model used in MacOS /usr/include/c++/v1/cstdlib
to determine if __builtin_ureachable is available
SIG and RRSIG records for private algorithms are supposed to contain
the name / OID of the algorithm used to generate them at the start
of the signature field.
It was discovered that MariaDB 10 didn't define LIBMARIADB leading
to compilation errors of MySQL DLZ modules on Debian stretch.
Use MARIADB_BASE_VERSION instead which is defined in all tested MariaDB
versions.
The DNS catalog zones draft version 5 document requires that catalog
zones consumers must reset the member zone's internal zone state when
its unique label changes (either within the same catalog zone or
during change of ownership performed using the "coo" property).
BIND already behaves like that, and, in fact, doesn't support keeping
the zone state during change of ownership even if the unique label
has been kept the same, because BIND always removes the member zone
and adds it back during unique label renaming or change of ownership.
Document the described behavior and add a log message to inform when
unique label renaming occurs.
Add a system test case with unique label renaming.
We check the `rdclass` to be of type IN in `dns_catz_update_process()`
function, and all the other static functions where similar checks exist
are called after (and in the result of) that function being called,
so they are effectively redundant.
There is already a check for the missing version property case
(catalog-bad1.example), and this new test should result in the same
outcome, but differs in a way that there exists a version record in the
zone, but it is of a wrong type (A instead of the expected TXT).
According to DNS catalog zones draft version 5 document, the CLASS field
of every RR in a catalog zone MUST be IN.
Add a new check in the catz system test to verify that a non-IN class
catalog zone (in this case CH) fails to load.
BIND does not support having a non-IN class RR in an IN class zone, or
non-IN class zone in an IN class view, so to verify that BIND respects
the mentioned restriction we must try to add a non-IN class catalog
zone and check that it didn't succeed.
The `named` configuration files had to be restructured to put all the
zones inside views, which also resulted in some corresponding changes
in the tests.sh script.
When parsing the configuration file, log a warning message in
configure_view() function when encountering a `catalog-zones`
option in a view with non-IN rdata class.
The DNS catalog zones draft version 5 document describes various
situations when a catalog zones must be considered as "broken" and
not be processed.
Implement those checks in catz.c and add corresponding system tests.
Add DNS extended errors 3 (Stale Answer) and 19 (Stale NXDOMAIN Answer)
to responses. Add extra text with the reason why the stale answer was
returned.
To test, we need to change the configuration such that for the first
set of tests the stale-refresh-time window does not interfer with the
expected extended errors.
In zone.c, the "me" strings were defined for functions that could be
traced with "ENTER" macro.
Use the __func__ that's defined by the compiler and is less prone to
copy&paste errors.
The shutdown test sends 'rdnc status' commands in parallel with
'rndc stop' A new rndc connection arriving will reference the ACL
environment to see whether the client is allowed to connect.
Commit c0995bc380 added a mutex lock to ns_interfacemgr_getaclenv(),
but if the new connection arrives while the interfaces are being
purged during shutdown, that lock is already being held. If the
the connection event slips in ahead of one of the netmgr's "stop
listening" events on a worker thread, a deadlock can occur.
The fix is not to hold the interfacemgr lock while shutting down
interfaces; only while actually traversing the interface list to
identify interfaces needing shutdown.
previously fctx_done() detached the fctx but did not clear the pointer
passed into it from the caller. in some conditions, when rctx_done()
was reached while waiting for a validator to complete, fctx_done()
could be called twice on the same fetch, causing a double detach.
fctx_done() now clears the fctx pointer, to reduce the chances of
such mistakes.
There is a possibility for `udp_recv()` to be called with `eresult`
being `ISC_R_SUCCESS`, but nevertheless with already deactivated `resp`,
which can happen when the request has been canceled in the meantime.
This commit ensures that write callbacks are getting called only after
the data has been sent via the network.
Without this fix, a situation could appear when a write callback could
get called before the actual encrypted data would have been sent to
the network. Instead, it would get called right after it would have
been passed to the OpenSSL (i.e. encrypted).
Most likely, the issue does not reveal itself often because the
callback call was asynchronous, so in most cases it should have been
called after the data has been sent, but that was not guaranteed by
the code logic.
Also, this commit removes one memory allocation (netievent) from a hot
path, as there is no need to call this callback asynchronously
anymore.
There was a query_detach() call missing in dig, which could lead to
dig hanging on TLS context creation errors. This commit fixes.
The error was introduced because the Strict TLS implementation was
initially made over an older version of the code, where this extra
query_detach() call was not needed.
This seems to be most appropriate way to ensure consistency between
release tarballs and public presentation on ReadTheDocs.
Previous attempt with removing docutils constraint, which relied on pip
depedency solver to pick the same packages as in CI was flawed. RTD
installs a bit different set of packages so it was inherently
unreliable.
As a result RTD pulled in sphinx-rtd-theme==0.4.3 while CI
had 1.0.0, and this inconsistency caused Table of Contents in Release
Notes to render incorrectly. Previous solution was to downgrade
docutils to < 0.17, but I think we should rather pin exact versions.
