This patch adds support for the OTR protocol to irssi. This is an import
of the external irssi-otr project that we are now taking over
maintership for.
Major thanks to the original authors of Irssi-OTR: Uli Meis and David
Goulet. Thanks to the OTR community in #OTR on OFTC, thanks to everyone
who have helped testing the patches and submitted UI suggestions.
Commit 6300dfec7 removed the option to disable SSL support from the
configure script since it became a requirement, but it also removed the
use of pkg-config for finding the OpenSSL library and its dependencies.
This had the unfortunate consequence of breaking the correct detection
of library flags in many static linking scenarios. In some cases, for
example, OpenSSL might have been built with zlib, which requires `-lz`
to be passed to the linker when doing a static link of the irssi
executable. Thus, pkg-config becomes an invaluable tool in such
situations, since no guessing work is needed as the OpenSSL .pc file
provides all the necessary flags.
So, this commit re-inserts the PKG_CHECK_MODULES macro in the configure
script when looking for OpenSSL. The test using AC_CHECK_LIB remains,
but only as a last resort in case the one using pkg-config fails.
Also, because the macro AM_PATH_GLIB_2_0 contains an unconditional call
to PKG_PROG_PKG_CONFIG, the OpenSSL checks are moved so that they come
after the Glib ones in order to avoid doubly checking for the pkg-config
binary (PKG_CHECK_MODULES skips that check if it has been performed
before, but PKG_PROG_PKG_CONFIG does not).
Use the following configure command:
$ ./configure --with-fuzzer --with-fuzzer-lib=/path/to/libFuzzer.a \
CC=clang CXX=clang++
Places an irssi-fuzz in src/fe-fuzz/ after build.
Also can specify SANFLAGS to override the chosen sanitizer flags
(defaults to "-g -fsanitize=address -fsanitize-coverage=trace-pc-guard").
This patch removes support for DANE validation of TLS certificates.
There wasn't enough support in the IRC community to push for this on the
majority of bigger IRC networks. If you believe this should be
reintroduced into irssi, then please come up with an implementation that
does not rely on the libval library. It is causing a lot of troubles for
our downstream maintainers.
This patch removes the optional checks for whether to build irssi with
TLS support or not. This will allow us to ship a default configuration
file where we connect to TLS enabled IRC servers out of the box.
