Instead of using bind() and passing the listening socket to the children
threads using uv_export/uv_import use one thread that does the accepting,
and then passes the connected socket using uv_export/uv_import to a random
worker. The previous solution had thundering herd problems (all workers
waking up on one connection and trying to accept()), this one avoids this
and is simpler.
The tcp clients quota is simplified with isc_quota_attach_cb - a callback
is issued when the quota is available.
nzf_append is conditionally compiled and this is intended to
catch error introduced by changes to the called functions on all
systems before the changes are run through the CI.
Per Current Mechanisms 2.3.5, the curve name is DER-encoded in the
EC_PARAMS attribute, and the public key value is DER-encoded in the
EC_POINT attribute.
Add recursive "test" and "unit" rules, which execute "make check"
in specific directories - "make test" runs the system tests, and
"make unit" runs the unit tests.
The libirs contained own re-implementations of the getaddrinfo,
getnameinfo and gai_strerror + irs_context and irs_dnsconf API that was
unused anywhere in the BIND 9.
Keep just the irs_resonf API that is being extensively used to parse
/etc/resolv.conf by several of BIND 9 tools.
The 'ephemeral' database implementation was used to provide a
lightweight database implemenation that doesn't cache results, and the
only place where it was really use is "samples" because delv is
overriding this to use "rbtdb" instead. Otherwise it was completely
unused.
* The 'ephemeral' cache DB (ecdb) implementation. An ecdb just provides
* temporary storage for ongoing name resolution with the common DB interfaces.
* It actually doesn't cache anything. The implementation expects any stored
* data is released within a short period, and does not care about the
* scalability in terms of the number of nodes.
The three libdns tests directly include ../dst_internal.h which
in turn directly include openssl headers, thus there was a missing
path and build failure on systems where OpenSSL is not in the default
include path.
this addresses a race that could occur during shutdown or when
reconfiguring to remove RPZ zones.
this change should ensure that the rpzs structure and the incremental
updates don't interfere with each other: rpzs->zones entries cannot
be set to NULL while an update quantum is running, and the
task should be destroyed and its queue purged so that no subsequent
quanta will run.
The rewrite of BIND 9 build system is a large work and cannot be reasonable
split into separate merge requests. Addition of the automake has a positive
effect on the readability and maintainability of the build system as it is more
declarative, it allows conditional and we are able to drop all of the custom
make code that BIND 9 developed over the years to overcome the deficiencies of
autoconf + custom Makefile.in files.
This squashed commit contains following changes:
- conversion (or rather fresh rewrite) of all Makefile.in files to Makefile.am
by using automake
- the libtool is now properly integrated with automake (the way we used it
was rather hackish as the only official way how to use libtool is via
automake
- the dynamic module loading was rewritten from a custom patchwork to libtool's
libltdl (which includes the patchwork to support module loading on different
systems internally)
- conversion of the unit test executor from kyua to automake parallel driver
- conversion of the system test executor from custom make/shell to automake
parallel driver
- The GSSAPI has been refactored, the custom SPNEGO on the basis that
all major KRB5/GSSAPI (mit-krb5, heimdal and Windows) implementations
support SPNEGO mechanism.
- The various defunct tests from bin/tests have been removed:
bin/tests/optional and bin/tests/pkcs11
- The text files generated from the MD files have been removed, the
MarkDown has been designed to be readable by both humans and computers
- The xsl header is now generated by a simple sed command instead of
perl helper
- The <irs/platform.h> header has been removed
- cleanups of configure.ac script to make it more simpler, addition of multiple
macros (there's still work to be done though)
- the tarball can now be prepared with `make dist`
- the system tests are partially able to run in oot build
Here's a list of unfinished work that needs to be completed in subsequent merge
requests:
- `make distcheck` doesn't yet work (because of system tests oot run is not yet
finished)
- documentation is not yet built, there's a different merge request with docbook
to sphinx-build rst conversion that needs to be rebased and adapted on top of
the automake
- msvc build is non functional yet and we need to decide whether we will just
cross-compile bind9 using mingw-w64 or fix the msvc build
- contributed dlz modules are not included neither in the autoconf nor automake
With the introduction of dnssec-policy, the aforementioned tools were
either rendered obsolete, or they will be replaced with dnssec-policy
based tools. Remove the tools and the requirement to have Python
installed. Python 3 is still being used for tests, so keep the autoconf
test, but make it much simpler.
Previously, the code would do:
REQUIRE(alg == CURVE1 || alg == CURVE2);
[...]
if (alg == CURVE1) { /* code for CURVE1 */ }
else { /* code for CURVE2 */ }
This approach is less extensible and also more prone to errors in case
the initial REQUIRE() is forgotten. The code has been refactored to
use:
REQUIRE(alg == CURVE1 || alg == CURVE2);
[...]
switch (alg) {
case CURVE1: /* code for CURVE1 */; break;
case CURVE2: /* code for CURVE2 */; break;
default: INSIST(0);
}
The pk11/constants.h header contained static CK_BYTE arrays and
we had to use #defines to pull only those we need. This commit
changes the constants to only define byte arrays with the content
and either use them directly or define the CK_BYTE arrays locally
where used.
