George Joseph	10664757d2	Add SHA-256 and SHA-512-256 as authentication digest algorithms ... * Refactored pjproject code to support the new algorithms and added a patch file to third-party/pjproject/patches * Added new parameters to the pjsip auth object: * password_digest = <algorithm>:<digest> * supported_algorithms_uac = List of algorithms to support when acting as a UAC. * supported_algorithms_uas = List of algorithms to support when acting as a UAS. See the auth object in pjsip.conf.sample for detailed info. * Updated both res_pjsip_authenticator_digest.c (for UAS) and res_pjsip_outbound_authentocator_digest.c (UAC) to suport the new algorithms. The new algorithms are only available with the bundled version of pjproject, or an external version > 2.14.1. OpenSSL version 1.1.1 or greater is required to support SHA-512-256. Resolves: #948 UserNote: The SHA-256 and SHA-512-256 algorithms are now available for authentication as both a UAS and a UAC. (cherry picked from commit a0987672f0)	3 months ago
George Joseph	a81c7c7030	Add C++ Standard detection to configure and fix a new C++20 compile issue ... * The autoconf-archive package contains macros useful for detecting C++ standard and testing other C++ capabilities but that package was never included in the install_prereq script so many existing build environments won't have it. Even if it is installed, older versions won't newer C++ standards and will actually cause an error if you try to test for that version. To make it available for those environments, the ax_cxx_compile_stdcxx.m4 macro has copied from the latest release of autoconf-archive into the autoconf directory. * A convenience wrapper(ast_cxx_check_std) around ax_cxx_compile_stdcxx was also added so checking the standard version and setting the asterisk-specific PBX_ variables becomes a one-liner: `AST_CXX_CHECK_STD([std], [force_latest_std])`. Calling that with a version of `17` for instance, will set PBX_CXX17 to 0 or 1 depending on whether the current c++ compiler supports stdc++17. HAVE_CXX17 will also be 'defined" or not depending on the result. * C++ compilers hardly ever default to the latest standard they support. g++ version 14 for instance supports up to C++23 but only uses C++17 by default. If you want to use C++23, you have to add `-std=gnu++=23` to the g++ command line. If you set the second argument of AST_CXX_CHECK_STD to "yes", the macro will automatically keep the highest `-std=gnu++` value that worked and pass that to the Makefiles. * The autoconf-archive package was added to install_prereq for future use. * Updated configure.ac to use AST_CXX_CHECK_STD() to check for C++ versions 11, 14, 17, 20 and 23. * Updated configure.ac to accept the `--enable-latest-cxx-std` option which will set the second option to AST_CXX_CHECK_STD() to "yes". The default is "no". * ast_copy_string() in strings.h declares the 'sz' variable as volatile and does an `sz--` on it later. C++20 no longer allows the `++` and `--` increment and decrement operators to be used on variables declared as volatile however so that was changed to `sz -= 1`.

George Joseph	393d8cb947	Add libjwt to third-party ... The current STIR/SHAKEN implementation is not currently usable due to encryption issues. Rather than trying to futz with OpenSSL and the the current code, we can take advantage of the existing capabilities of libjwt but we first need to add it to the third-party infrastructure already in place for jansson and pjproject. A few tweaks were also made to the third-party infrastructure as a whole. The jansson "dest" install directory was renamed "dist" to better match convention, and the third-party Makefile was updated to clean all product directories not just the ones currently in use.

George Joseph	90069a94b0	apply_patches: Sort patch list before applying ... The apply_patches script wasn't sorting the list of patches in the "patches" directory before applying them. This left the list in an indeterminate order. In most cases, the list is actually sorted but rarely, they can be out of order and cause dependent patches to fail to apply. We now sort the list but the "sort" program wasn't in the configure scripts so we needed to add that and regenerate the scripts as well. Resolves: #193	2 years ago

Mike Bradeen	58636a6ea6	res_pjsip: Upgraded bundled pjsip to 2.13 ... Removed multiple patches. Code chages in res_pjsip_pubsub due to changes in evsub. Pjsip now calls on_evsub_state() before on_rx_refresh(), so the sub tree deletion that used to take place in on_evsub_state() now must take place in on_rx_refresh(). Additionally, pjsip now requires that you send the NOTIFY from within on_rx_refresh(), otherwise it will assert when going to send the 200 OK. The idea is that it will look for this NOTIFY and cache it until after sending the response in order to deal with the self-imposed message mis-order. Asterisk previously dealt with this by pushing the NOTIFY in on_rx_refresh(), but pjsip now forces us to use it's method. Changes were required to configure in order to detect which way pjsip handles this as the two are not compatible for the reasons mentioned above. A corresponding change in testsuite is required in order to deal with the small interal timing changes caused by moving the NOTIFY send.

George Joseph	0adcdbd118	BuildSystem: Check for alternate openssl packages ... OpenSSL is one of those packages that often have alternatives with later versions. For instance, CentOS/EL 7 has an openssl package at version 1.0.2 but there's an openssl11 package from the epel repository that has 1.1.1. This gets installed to /usr/include/openssl11 and /usr/lib64/openssl11. Unfortunately, the existing --with-ssl and --with-crypto ./configure options expect to point to a source tree and don't work in this situation. Also unfortunately, the checks in ./configure don't use pkg-config. In order to make this work with the existing situation, you'd have to run... ./configure --with-ssl=/usr/lib64/openssl11 \ --with-crypto=/usr/lib64/openssl11 \ CFLAGS=-I/usr/include/openssl11 BUT... those options don't get passed down to bundled pjproject so when you run make, you have to include the CFLAGS again which is a big pain. Oh... To make matters worse, although you can specify PJPROJECT_CONFIGURE_OPTS on the ./configure command line, they don't get saved so if you do a make clean, which will force a re-configure of bundled pjproject, those options don't get used. So... * In configure.ac... Since pkg-config is installed by install_prereq anyway, we now use it to check for the system openssl >= 1.1.0. If that works, great. If not, we check for the openssl11 package. If that works, great. If not, we fall back to just checking for any openssl. If pkg-config isn't installed for some reason, or --with-ssl=<dir> or --with-crypto=<dir> were specified on the ./configure command line, we fall back to the existing logic that uses AST_EXT_LIB_CHECK(). * The whole OpenSSL check process has been moved up before THIRD_PARTY_CONFIGURE(), which does the initial pjproject bundled configure, is run. This way the results of the above checks, which may result in new include or library directories, is included. * Although not strictly needed for openssl, We now save the value of PJPROJECT_CONFIGURE_OPTS in the makeopts file so it can be used again if a re-configure is triggered.

lvl	b08427134f	Introduce astcachedir, to be used for temporary bucket files ... As described in the issue, /tmp is not a suitable location for a large amount of cached media files, since most distributions make /tmp a RAM-based tmpfs mount with limited capacity. I opted for a location that can be configured separately, as opposed to using a subdirectory of spooldir, given the different storage profile (transient files vs files that might stay there indefinitely). This commit just makes the cache directory configurable, and changes the default location from /tmp to /var/cache/asterisk.

Alexander Traud	610e058189	BuildSystem: Search for Python/C API when possibly needed only. ... The Python/C API is used only if the Test Framework was enabled in Asterisk 'make menuselect'. The Test Framework is available only if the Developer Mode was enabled in Asterisk './configure --enable-dev-mode'. And that Python/C API is used only if the PJProject was found and not disabled in Asterisk; the user did not go for './configure --without-pjproject'. Furthermore, because version 2 of that Python/C API is required (currently) and because some platforms do not offer a generic version 2, the script searches for 2.7 explicitly as well. To avoid version mismatch between the Python/C API and the Python environment, the script searches for the latter in the same versions, in the same the order as well. Because this Python/C API is just for (some) Asterisk contributors, the script also goes for the Python 3 environment as a last resort for all other Asterisk users. This allows 'make full' even on minimal installations of Ubuntu 18.04 LTS and newer. Because the Python/C API is Asterisk contributor specific, the Python packages are removed from the script './contrib/scripts/install_prereq' as this script is intended for Asterisk users.

Ben Ford	168637cc0c	RTP/ICE: Send on first valid pair. ... When handling ICE negotiations, it's possible that there can be a delay between STUN binding requests which in turn will cause a delay in ICE completion, preventing media from flowing. It should be possible to send media when there is at least one valid pair, preventing this scenario from occurring. A change was added to PJPROJECT that adds an optional callback (on_valid_pair) that will be called when the first valid pair is found during ICE negotiation. Asterisk uses this to start the DTLS handshake, allowing media to flow. It will only be called once, either on the first valid pair, or when ICE negotiation is complete.

Sebastian Kemper	ccac55b894	loader: support for permanent dlopen() ... Asterisk assumes that dlopen() will always run the constructor of a shared library and every dlclose() will run its destructor. But dlopen() may be permanent, meaning the constructor will only be run once, as is the case with musl libc. With a permanent dlopen() the Asterisk module loader does not work correctly, because it's expectations regarding when the constructors and destructors are run are not met. In fact a segmentation fault will occur when the first module is "re-opened" that has AST_MODFLAG_GLOBAL_SYMBOLS set (the dlopen() does not call the constructor, resource_being_loaded is not set to NULL, then strlen is called with NULL instead of a string, see issue ASTERISK-28319). This commit adds code to the loader that will manually run the constructors/destructors of the (non-builtin) modules where needed. To achieve this a new ao2 container (linked list) is started and filled with objects that contain the names of the modules and the pointers to their respective info structs. This behavior can be activated when configuring Asterisk (--enable-permanent-dlopen). By default this is disabled, of course.
