This commit converts the license handling to adhere to the REUSE
specification. It specifically:
1. Adds used licnses to LICENSES/ directory
2. Add "isc" template for adding the copyright boilerplate
3. Changes all source files to include copyright and SPDX license
header, this includes all the C sources, documentation, zone files,
configuration files. There are notes in the doc/dev/copyrights file
on how to add correct headers to the new files.
4. Handle the rest that can't be modified via .reuse/dep5 file. The
binary (or otherwise unmodifiable) files could have license places
next to them in <foo>.license file, but this would lead to cluttered
repository and most of the files handled in the .reuse/dep5 file are
system test files.

There is a checkds system test in v9_16 that does not exist in the
main branch. This existing checkds system test checks the behaviour of
the dnssec-checkds tool. Before backporting the new checkds system
test, that tests the feature where BIND checks periodically the
parental agents if the DS for a given KSK has been published, move the
existing checkds system test to checkdstool.
"resolve" is used by the resolver system tests, and I'm not
certain whether delv exercises the same code, so rather than
remove it, I moved it to bin/tests/system.

sample code for export libraries is no longer needed and
this code is not used for any internal tests. also, sample-gai.c
had already been removed but there were some dangling references.
(cherry picked from commit 056afe7bdc)
the libdns client API is no longer being maintained for
external use, we can remove the code that isn't being used
internally, as well as the related tests.

The custom ISC SPNEGO mechanism implementation is no longer needed on
the basis that all major Kerberos 5/GSSAPI (mit-krb5, heimdal and
Windows) implementations support SPNEGO mechanism since 2006.
This commit removes the custom ISC SPNEGO implementation, and removes
the option from both autoconf and win32 Configure script. Unknown
options are being ignored, so this doesn't require any special handling.
* Following the example set in 634bdfb16d, the tlsdns netmgr
module now uses libuv and SSL primitives directly, rather than
opening a TLS socket which opens a TCP socket, as the previous
model was difficult to debug. Closes#2335.
* Remove the netmgr tls layer (we will have to re-add it for DoH)
* Add isc_tls API to wrap the OpenSSL SSL_CTX object into libisc
library; move the OpenSSL initialization/deinitialization from dstapi
needed for OpenSSL 1.0.x to the isc_tls_{initialize,destroy}()
* Add couple of new shims needed for OpenSSL 1.0.x
* When LibreSSL is used, require at least version 2.7.0 that
has the best OpenSSL 1.1.x compatibility and auto init/deinit
* Enforce OpenSSL 1.1.x usage on Windows

The BIND 9 libraries are considered to be internal only and hence the
API and ABI changes a lot. Keeping track of the API/ABI changes takes
time and it's a complicated matter as the safest way to make everything
stable would be to bump any library in the dependency chain as in theory
if libns links with libdns, and a binary links with both, and we bump
the libdns SOVERSION, but not the libns SOVERSION, the old libns might
be loaded by binary pulling old libdns together with new libdns loaded
by the binary. The situation gets even more complicated with loading
the plugins that have been compiled with few versions old BIND 9
libraries and then dynamically loaded into the named.
We are picking the safest option possible and usable for internal
libraries - instead of using -version-info that has only a weak link to
BIND 9 version number, we are using -release libtool option that will
embed the corresponding BIND 9 version number into the library name.
That means that instead of libisc.so.1608 (as an example) the library
will now be named libisc-9.16.10.so.

This commit extends the perl Configure script to also check for libssl
in addition to libcrypto and change the vcxproj source files to link
with both libcrypto and libssl.
As of libuv 1.36.0, CMake is the only supported build method for libuv
on Windows. Account for that fact by adjusting the relevant paths and
DLL file names used in the win32utils/Configure script. Update
Windows-specific documentation accordingly.

The ARM and the manpages have been converted into Sphinx documentation
format.
Sphinx uses reStructuredText as its markup language, and many of its
strengths come from the power and straightforwardness of
reStructuredText and its parsing and translating suite, the Docutils.

Windows BIND releases produced by GitLab CI are built from Git
repositories, not from release tarballs, which means the "srcid" file is
not present in the top source directory when MSBuild is invoked. This
causes the Git commit hash for such builds to be set to "unset_id".
Enable win32utils/Configure to try determining the commit hash for a
build by invoking Git on the build host if the "srcid" file is not
present (which is what its Unix counterpart does).
(cherry picked from commit 05e13e7caf)
HAVE_UV_IMPORT and other config.h macros must not be set unconditionally
because no existing libuv release exposes uv_import() and/or uv_export()
yet. Windows builds not passing an explicit path to libuv to
win32utils/Configure are currently broken because of this, so comment
out the offending lines and describe when the aforementioned config.h
macros should be set.
(cherry picked from commit 57b430b8ca)
The change introduced by commit be159f5565
was not fully complete. Adjust ./configure summary so that it reflects
the new way the --with-tuning switch works, fixing the Autoconf variable
used for determining the value of that switch. Fix win32utils/Configure
so that it behaves the same way as its Unix counterpart.
(cherry picked from commit a5fc3a6364)
We were using our own versions of isc_uv_{export,import} functions
for multithreaded TCP listeners. Upcoming libuv version will
contain proper uv_{export,import} functions - use them if they're
available.
These functions can be used to pass a uv handle between threads in a
safe manner. The other option is to use uv_pipe and pass the uv_handle
via IPC, which is way more complex. uv_export() and uv_import() functions
existed in libuv at some point but were removed later. This code is
based on the original removed code.
The Windows version of the code uses two functions internal to libuv;
a patch for libuv is attached for exporting these functions.
Commit 09ac224c5c made dnssec-keygen
depend on libisccfg but the Visual Studio solution file was not updated
to reflect that change. Make sure the dnssec-keygen Visual Studio
project depends on the libisccfg project to prevent compilation issues
during parallel builds.
This is a replacement for the existing isc_socket and isc_socketmgr
implementation. It uses libuv for asynchronous network communication;
"networker" objects will be distributed across worker threads reading
incoming packets and sending them for processing.
UDP listener sockets automatically create an array of "child" sockets
so each worker can listen separately.
TCP sockets are shared amongst worker threads.
A TCPDNS socket is a wrapper around a TCP socket, which handles the
the two-byte length field at the beginning of DNS messages over TCP.
(Other wrapper socket types can be implemented in the future to handle
DNS over TLS, DNS over HTTPS, etc.)
Commit afa81ee4e4 omitted some spots in
the source tree which are still referencing the removed --with-cc-alg
"configure" option. Make sure the latter is removed completely.
Bring the files describing Windows-specific aspects of building and
installing BIND up to date. Remove the parts which are either outdated
(e.g. 32-bit build instructions), already included elsewhere (e.g. the
list of Windows systems BIND is known to run on), or inconvenient to
keep up to date in the long run (e.g. ARM chapter numbers).
Until now, the build process for BIND on Windows involved upgrading the
solution file to the version of Visual Studio used on the build host.
Unfortunately, the executable used for that (devenv.exe) is not part of
Visual Studio Build Tools and thus there is no clean way to make that
executable part of a Windows Server container.
Luckily, the solution upgrade process boils down to just adding XML tags
to Visual Studio project files and modifying certain XML attributes - in
files which we pregenerate anyway using win32utils/Configure. Thus,
extend win32utils/Configure with three new command line parameters that
enable it to mimic what "devenv.exe bind9.sln /upgrade" does. This
makes the devenv.exe build step redundant and thus facilitates building
BIND in Windows Server containers.
Build configuration for the dnssec-cds Visual Studio project is absent
from the solution file template, which means the solution needs to be
upgraded using "devenv bind9.sln /upgrade" in order for the dnssec-cds
project to be built. Add the build configuration for dnssec-cds to the
solution file template so that upgrading the solution is not necessary
for building that project.
When commit 8eb88aafee removed liblwres,
it also modified nsupdate to use libirs instead of liblwres, but the
Visual Studio project files were not updated to reflect that change.
Make sure the nsupdate Visual Studio project depends on the libirs
project to prevent compilation issues during parallel builds.
The isc-config.sh script was introduced before pkg-config as is a purely
historical thing. There are two reason for removal of isc-config.sh scripts:
a) The BIND 9 libraries are now meant to be used only from BIND 9, so there's no
reason to provide convenience script to link with the libraries.
b) Even if that was not the case, we should and would replace the isc-config.sh
with respective pkg-config (.pc) file for every library.
- added a 'hookdata' array to qctx to store pointers to up to
16 blobs of data which are allocated by modules as needed.
each module is assigned an ID number as it's loaded, and this
is the index into the hook data array. this is to be used for
holding persistent state between calls to a hook module for a
specific query.
- instead of using qctx->filter_aaaa, we now use qctx->hookdata.
(this was the last piece of filter-aaaa specific code outside the
module.)
- added hook points for qctx initialization and destruction. we get
a filter-aaaa data pointer from the mempool when initializing and
store it in the qctx->hookdata table; return to to the mempool
when destroying the qctx.
- link the view to the qctx so that detaching the client doesn't cause
hooks to fail
- added a qctx_destroy() function which must be called after qctx_init;
this calls the QCTX_DESTROY hook and detaches the view
- general cleanup and comments
