Commit b580eb2fb3 inadvertently caused
dnstap-related man pages to be installed unconditionally. Ensure they
are only installed for dnstap-enabled builds.
The unittest.sh script tried to execute the unit tests when cmocka
development libraries was available, but kyua, the execution engine,
was not. Now, both need to be installed in the system.
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.
(cherry picked from commit 9fb6d11abb)
Originally, every library and binaries got linked to everything, which
creates unnecessary overlinking. This wasn't as straightforward as it
should be as we still support configuration without libtool for 9.16.
Couple of smaller issues related to include headers and an issue where
sanitizer overload dlopen and dlclose symbols, so we were getting false
negatives in the autoconf test.
Revert the change from ad03c22e97 as
further testing has shown that with hyper-threading disabled, named with
ISC rwlocks outperforms named with pthread rwlocks in cold cache testing
scenarios. Since building named with pthread rwlocks might still be a
better choice for some workloads, keep the compile-time option which
enables that.

- the configuration summary reported zlib compression was not
supported even when it was.
- when bind.keys.h was regenerated it violated clang-format style.

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.
The new ISC_THREAD_LOCAL macro unifies usage of platform dependent
Thread Local Storage definition thread_local vs __thread vs
__declspec(thread) to a single macro.
The commit also unifies the required level of support for TLS as for
some parts of the code it was mandatory and for some parts of the code
it wasn't.
-Wl,-z,interpose is not supported.
-Wl,rpath=<path> is not supported use -Wl,rpath,<path> instead.
Use @SO@ for loadable extension.
Use -L <path> -l libwrap instead of libwrap.sa.
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.
`/usr/share/sgml/docbook/xsl-stylesheets` and `/usr/share/dblatex` are
places where docbook-style-xsl and, respectively, dblatex packages on
Red Hat systems put their XSL templates. Unless we hint this place it
has to be added to `./configure` manually (`--with-docbook-xsl=...`):

Weak symbols are handled differently by different dynamic linkers. With
glibc, lib/dns/tests/tkey_test works as expected no matter whether
--with-libtool is used or not: __attribute__((weak)) prevents a static
build from failing and it just so happens that the desired symbols are
picked at runtime for dynamic builds. However, with BSD libc, the
libdns functions called from lib/dns/tests/tkey_test.c use the "real"
memory allocation functions from libisc, thus breaking that unit test.
(Note: similar behavior can be reproduced with glibc by setting the
LD_DYNAMIC_WEAK environment variable.)
The simplest way to make lib/dns/tests/tkey_test work reliably is to
drop all uses of __attribute__((weak)) in it - this way, the memory
functions inside lib/dns/tests/tkey_test.c will always be used instead
of the "real" libisc ones for dynamic builds. However, this would not
work with static builds as it would result in multiple strong symbols
with the same name being present in a single binary.
Work around the problem by only compiling in the overriding definitions
of memory functions when building using --with-libtool. For static
builds, keep relying on the --wrap linker option for replacing calls to
the functions we are interested in.
Add check for creating new EVP_PKEY with EVP_PKEY_SIPHASH, but disable SipHash
on OpenSSL 1.1.1 as the hash length initialization is broken before OpenSSL
1.1.1a release.
The change fixes the following build failure on sparc T3 and older CPUs:
```
sparc-unknown-linux-gnu-gcc ... -O2 -mcpu=niagara2 ... -c rwlock.c
{standard input}: Assembler messages:
{standard input}:398: Error: Architecture mismatch on "pause ".
{standard input}:398: (Requires v9e|v9v|v9m|m8; requested architecture is v9b.)
make[1]: *** [Makefile:280: rwlock.o] Error 1
```
`pause` insutruction exists only on `-mcpu=niagara4` (`T4`) and upper.
The change adds `pause` configure-time autodetection and uses it if available.
config.h.in got new `HAVE_SPARC_PAUSE` knob. Fallback is a fall-through no-op.
Build-tested on:
- sparc-unknown-linux-gnu-gcc (no `pause`, build succeeds)
- sparc-unknown-linux-gnu-gcc -mcpu=niagara4 (`pause`, build succeeds)

There's no strong reason to keep `make tags` in our build system. The previous
functionality of `make tags` could be simply retained by aliasing variant of:
etags $(git ls-files '*.c' '*.h')
which would be universal for all C-code projects.
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.
This commit changes the BIND cookie algorithms to match
draft-sury-toorop-dnsop-server-cookies-00. Namely, it changes the Client Cookie
algorithm to use SipHash 2-4, adds the new Server Cookie algorithm using SipHash
2-4, and changes the default for the Server Cookie algorithm to be siphash24.
Add siphash24 cookie algorithm, and make it keep legacy aes as
