- Check that an NS in an authority section returned from a forwarder
which is above the name in a configured "forward first" or "forward
only" zone (i.e., net/NS in a response from a forwarder configured for
local.net) is not cached.
- Test that a DNAME for a parent domain will not be cached when sent
in a response from a forwarder configured to answer for a child.
- Check that glue is rejected if its name falls below that of zone
configured locally.
- Check that an extra out-of-bailiwick data in the answer section is
not cached (this was already working correctly, but was not explicitly
tested before).
Related: CVE-2021-25220
5817. [security] The rules for acceptance of records into the cache
have been tightened to prevent the possibility of
poisoning if forwarders send records outside
the configured bailiwick. (CVE-2021-25220) [GL #2950]

5818. [security] A synchronous call to closehandle_cb() caused
isc__nm_process_sock_buffer() to be called recursively,
which in turn left TCP connections hanging in the
CLOSE_WAIT state blocking indefinitely when
out-of-order processing was disabled. (CVE-2022-0396)

Resolves: CVE-2022-0396
BIND reads default system port ranges from /proc file. Propagate just
that single file to bind chroot. Defaults should be therefore the same
as on named.service.
Resolves: rhbz#2013595
Previously, named would run with a configuration where *-source-v6 (notify-source-v6,
transfer-source-v6 and query-source-v6) address and port could be simultaneously used
for listening. This is no longer true for BIND 9.16+ and the code that would do
interface adjustments would unexpectedly disable listening on TCP for such interfaces.

Resolves CVE-2021-25215 and CVE-2021-25214.
Removes disable-isc-spnego flag, because custom isc spnego code were
removed with also this flag. It is default (and the only) option now.

It prevents compilation of bind-dyndb-ldap. Because config.h is never
used by bind-dyndb-ldap, stop exporting it in devel package. It should
be only implementation detail.

Resolves: rhbz#1956777
Reworked custom redhat version. Complete version is now part of library
names. Libraries are not recommended for any third party application.
They are still required for bind-dyndb-ldap only.
Version of named changed, only suffix -RH is appended to upstream
version. Therefore dig would not contain version
9.6.11-RedHat-9.6.11-1.fc34, but only 9.6.13-RH. Version of fedora build
have to be obtained from rpm -q bind.
Version is now part of library names, bind-libs-lite was merged to
bind-libs. bind-dyndb-ldap needs whole bind, no point to offer smaller
library set just for its dependencies.
Updated also named(8) manual page to match current state of SELinux.
