The wait until zones are signed after rndc reconfig is broken
because the zones are already signed before the reconfig. Fix
by having a different way to ensure the signing of the zone is
complete. This does require a call to the "wait_for_done_signing"
function after each "check_keys" call after the ns6 reconfig.
The "wait_for_done_signing" looks for a (newly added) debug log
message that named will output if it is done signing with a certain
key.
isc__nm_tcpdns_send() was not asynchronous and accessed socket
internal fields in an unsafe manner, which could lead to a race
condition and subsequent crash. Fix it by moving tcpdns processing
to a proper netmgr thread.
We need to mark the socket as inactive early (and synchronously)
in the stoplistening process; otherwise we might destroy the
callback argument before we actually stop listening, and call
the callback on bad memory.

Add a note why we don't have a test case for the issue.
It is tricky to write a good test case for this if our tools are
not allowed to create signatures for unsupported algorithms.

enough buffer space. Also change named_os_uname() prototype so
that it is now returning (const char *) rather than (char *). If
uname() is not supported on a UNIX build prepopulate unamebuf[]
with "unknown architecture".
The LT_INIT() call in configure.ac is effectively a no-op because it is
preceded by a call to AC_PROG_LIBTOOL(), which is the previous name of
LT_INIT() used in older libtool versions. Replace AC_PROG_LIBTOOL()
with AC_PATH_PROG() to look for libtool in PATH without initializing it,
which is the originally intended behavior.
Without this change, --enable-static is used by default, which causes a
plain ./configure invocation to fail because static linking is now
disallowed. Drop --disable-static from the ./configure invocations used
in GitLab CI to test this scenario continuously.
Linking BIND 9 programs and libraries statically disables several
important features:
* dlopen() - relied on by dynamic loading of modules, dlz, and dyndb,
* RELRO (read-only relocations) and ASLR (address space layout
randomization) - security features which are important for any
program interacting with the network and/or user input.
Disable and disallow linking BIND 9 binaries statically, thus enforcing
dlopen() support and allowing use of RELRO and ASLR by default.
The `rndc` argument was always overridden by the static configuration,
because the logic for handling the number of dnstap files to retain
was both backwards and a bit redundant.
When maintainer mode is enabled (./configure --enable-maintainer-mode)
it enables rebuild of documentation source files that require extra
tools to be installed or compiled. For a convenience, those files are
already committed into the repository and their rebuild is not required
to build BIND 9 from sources.
Similarly, the manpage sources will get rebuild only when in maintainer
mode because they require sphinx-build to be available locally and that
might not be always the case.
The files in doc/misc requires all the BIND 9 libraries to be built
before the documentation can be built. One of the extra automake
features is maintainer mode that allows to conditionally build and clean
files that require special tools. Make use of the automake maintainer
mode to not rebuild the files in doc/misc under normal circumstances.
if tests that take a particularly long time to complete
(serve-stale, dnssec, rpzrecurse) are run first, a parallel
run of the system tests can finish 1-2 minutes faster.
The doc/misc/options is used to generate a file describing all
configuration options. Currently, the file contents could differ
based on ./configure option which is kind of suboptimal.
We already removed the "// not configured" from the options.active, and
this time we remove generation of the string altogether.
these keywords were added to the parser as synonyms for "master"
and "slave" but were never hooked in to the configuration of named,
so they were ignored. this has been fixed and the option is now
checked for correctness.
