for testing purposes, we need to be able to specify a library path from
which to load the dnsrps implementation. this can now be done with the
"dnsrps-library" option.
DNSRPS can now be enabled in configure regardless of whether librpz.so
is currently installed on the system.
formerly if a connection failed in dns_request, the callback
function was called with ISC_R_CANCELED. change this to the
actual result code so the failure is correctly reported.
when isc_nm_listenstreamdns() is called with a local port of 0,
a random port is chosen. call uv_getsockname() to determine what
the port is as soon as the socket is bound, and add a function
isc_nmsocket_getaddr() to retrieve it, so that the caller can
connect to the listening socket. this will be used in cases
where the same process is acting as both client and server.
add a public function ns_interface_create() allowing the caller
to set up a listening interface directly without having to set
up listen-on and scan network interfaces.
the new dns_view_addtrustedkey() function allows a view's trust
anchors to be updated directly. this code was formerly in
dns_client_addtrustedkey(), which is now a wrapper around
dns_view_addtrustedkey().
The dns__catz_update_cb() function was earlier updated (see
d2ecff3c4a) to use a separate
'dns_db_t' object ('catz->updb' instead of 'catz->db') to
avoid a race between the 'dns__catz_update_cb()' and
'dns_catz_dbupdate_callback()' functions, but the 'REQUIRE'
check there still checks the validity of the 'catz->db' object.
Fix the omission.
Simplify the stopping of the generic socket children by using the
isc_async API from the loopmgr instead of using the asychronous
netievent mechanism in the netmgr.
Simplify the setting of the TLS contexts by using the isc_async API
from the loopmgr instead of using the asychronous netievent mechanism in
the netmgr.
Simplify the canceling of the StreamDNS socket by using the isc_async API
from the loopmgr instead of using the asychronous netievent mechanism in
the netmgr.
Simplify the reading from the StreamDNS socket by using the isc_async API
from the loopmgr instead of using the asychronous netievent mechanism in
the netmgr.
Simplify the setting of the DoH endpoints by using the isc_async API
from the loopmgr instead of using the asychronous netievent mechanism in
the netmgr.
Simplify the acception the new TCP connection by using the isc_async API
from the loopmgr instead of using the asychronous netievent mechanism in
the netmgr.
Simplify the canceling of the UDP socket by using the isc_async API
from the loopmgr instead of using the asychronous netievent mechanism in
the netmgr.
Simplify the stopping of the TCP children by using the isc_async API
from the loopmgr instead of using the asychronous netievent mechanism in
the netmgr.
Simplify the starting of the TCP children by using the isc_async API
from the loopmgr instead of using the asychronous netievent mechanism in
the netmgr.
Simplify the stopping of the UDP children by using the isc_async API
from the loopmgr instead of using the asychronous netievent mechanism in
the netmgr.
Simplify the starting of the UDP children by using the isc_async API
from the loopmgr instead of using the asychronous netievent mechanism in

The active handles accounting was both using atomic counter and ISC_LIST
to keep track of active handles. Remove the atomic counter that was in
use before the ISC_LIST was added for better tracking of the handles
attached to the socket.
Instead of calling isc__nmhandle_detach calling
nmhandle_detach_cb() asynchronously when there's closehandle_cb
initialized, convert the closehandle_cb to use isc_job, and make the
isc__nmhandle_detach() to be fully synchronous.
The netmgr connect, read and send callbacks can now only be executed on
the same loop, convert it from asynchronous netievent queue event to
more direct isc_job.
These options and zone type were created to address the
SiteFinder controversy, in which certain TLD's redirected queries
rather than returning NXDOMAIN. since TLD's are now DNSSEC-signed,
this is no longer likely to be a problem.
The deprecation message for 'type delegation-only' is issued from
the configuration checker rather than the parser. therefore,
isccfg_check_namedconf() has been modified to take a 'nodeprecate'
parameter to suppress the warning when named-checkconf is used with
the command-line option to ignore warnings on deprecated options (-i).
When resquery_response() was called with ISC_R_SHUTTINDOWN, the region
argument would be NULL, but rctx_respinit() would try to pass
region->base and region->len to the isc_buffer_init() leading to
a NULL pointer dereference. Properly handle non-ISC_R_SUCCESS by
ignoring the provided region.
This should delay the catalog zone from being destroyed during
shutdown, if the update process is still running.
Doing this should not introduce significant shutdown delays, as
the update function constantly checks the 'shuttingdown' flag
and cancels the process if it is set.
stop and restart the server in the 'tsiggss' test, in order
to confirm that GSS negotiated TSIG keys are saved and restored
when named loads.
added logging to dns_tsigkey_createfromkey() to indicate whether
a key has been statically configured, generated via GSS negotiation,
or restored from a file.
If the zone already has existing NSEC/NSEC3 chains then zone_sign
needs to continue to use them. If there are no chains then use
kasp setting otherwise generate an NSEC chain.
BIND needs a collection of standard lock-free data structures,
which we can find in liburcu, along with its RCU safe memory
reclamation machinery. We will use liburcu's QSBR variant instead
of the home-grown isc_qsbr.
ISC_REFCOUNT_TRACE_IMPL uses isc_tid(), but the corresponding header
file is not included, which breaks, for example, compiling BIND with
DNS_CATZ_TRACE defined in lib/dns/include/dns/catz.h.
Add '#include <isc/tid.h>' in lib/isc/include/isc/refcount.h.
In base32_decode_char the GCC 12 static analyser fails to determine
that ctx->val[1], ctx->val[3], ctx->val[4] and ctx->val[6] are
assigned values by the previous call to base32_decode_char. Initialise
ctx->val to zeros when initalising the rest of ctx to silence the
false positive.
REQUIRE that rdata->type is dns_rdatatype_svcb to detect when
dns_rdata_checksvcb is called with the wrong rdata type. There are
no code paths that currently pass the wrong rdata to dns_rdata_checksvcb.
This was found by GCC 12 static analysis.
Rename and simplify dst__openssl_compare_keypair() to
dst__openssl_keypair_compare(), and introduce two additional functions
dst__openssl_keypair_isprivate and dst__openssl_keypair_destroy.
Use those to de-duplicated openssl{rsa,ecdsa}_isprivate, and
openssl{rsa,ecdsa}_destroy.
