libidn2 defaults to UseSTD3ASCIIRules=false. That allows arbitrary ASCII
characters to show up in the toASCII output, including space and
underscore. Enable IDN2_USE_STD3_ASCII_RULES to the libidn2 conversion
to disallow additional characters from the conversion (see Validity
Criteria[1]).
The AX_CHECK_JEMALLOC() m4 macro sets the JEMALLOC_CFLAGS variable, not
JEMALLOC_CPPFLAGS. Furthermore, the JEMALLOC_CFLAGS and JEMALLOC_LIBS
variables should only be included in the build flags if jemalloc was
successfully configured. Tweak lib/isc/Makefile.am accordingly.
Remove the dynamic registration of result codes. Convert isc_result_t
from unsigned + #defines into 32-bit enum type in grand unified
<isc/result.h> header. Keep the existing values of the result codes
even at the expense of the description and identifier tables being
unnecessary large.
Additionally, add couple of:
switch (result) {
[...]
default:
break;
}
statements where compiler now complains about missing enum values in the
switch statement.
Previously, when using compiler without support for static assertions,
the STATIC_ASSERT() macro would be replaced with runtime assertion.
Change the STATIC_ASSERT() macro to a version that's compile time
assertion even when using pre-C11 compilers.

Both <isccc/util.h> and <isc/util.h> defined DE_CONST() macro. As
<isccc/util.h> header includes <isc/util.h>, remove the macro from
<isccc/util.h> header.
There's value mismatch between the return type of dns_rrl() that's
dns_rrl_result_t and ISC_R_SUCCESS which belongs to isc_result_t. This
works incidentally, because DNS_RRL_RESULT_OK == ISC_R_SUCCESS.
This would break when we change isc_result_t to be static enum in
consecutive commit. Change the value to match the type.
Renamed some functions for clarity and readability:
- dns_dispatch_addresponse() -> dns_dispatch_add()
- dns_dispatch_removeresponse() -> dns_dispatch_done()
The dns_dispatch_cancel() function now calls dns_dispatch_done()
directly, so it is no longer ever necessary to call both functions.
dns_dispatch_cancel() is used to terminate dispatch connections
that are still pending, while dns_dispatch_done() is used when they
are complete.
The build would fail if the OpenSSL libraries were not in default
include path because we include <openssl/opensslv.h> header in
lib/bind9/check.c. Add $(OPENSSL_CFLAGS) to lib/bind9/Makefile.am.
This commit fixes a crash in DoT code when it was attempting to call a
read callback on the later stages of the connection when it is not
available.
It also fixes [GL #2884] (back-trace provided in the bug report is
exactly the same as was seen when fixing this problem).
This commit makes dig fail with error in case a zone transfer is
attempted over a connections where ALPN was not negotiated. All other
request types will work fine.
This commit make the code handling incoming zone transfers to verify
if they are allowed to be done over the underlying connections. As a
result the check ensures that the "dot" ALPN token has been negotiated
over the underlying connection.
This commit makes BIND verify that zone transfers are allowed to be
done over the underlying connection. Currently, it makes sense only
for DoT, but the code is deliberately made to be protocol-agnostic.
The intention of having this function is to have a predicate to check
if a zone transfer could be performed over the given handle. In most
cases we can assume that we can do zone transfers over any stream
transport except DoH, but this assumption will not work for zone
transfers over DoT (XoT), as the RFC9103 requires ALPN to happen,
which might not be the case for all deployments of DoT.
The 'listenlist_test', 'notify_test', and 'query_test' tests failed
when the descriptor limit was 256 on MacOS 11.6 with 8 cpus. On the
test platform the limit needed to be increased to ~400. Increase
the limit to at least 1024 to give some head room.
as libdns is no longer exported, it's not necessary to have
init and shutdown functions. the only purpose they served
was to create a private mctx and run dst_lib_init(), which
can be called directly instead.
