* refactor/dtls: Use message oriented send/receive for DTLS.Garrett D'Amore2025-11-10
| | | | The protocol here needs to know and respect message boundaries.
* fixes #2173 New TLS cert API - replaces the properties for CN and ALTNAMES.Garrett D'Amore2025-10-05
| | | | | | This will replace the NNG_OPT_TLS_PEER_ALTNAMES and NNG_OPT_TLS_PEER_CN properties, and gives a bit more access to the certificate, as well as direct access to the raw DER form, which should allow use in other APIs.
* Various header file fixes... also fix compilation errors when HTTP is disabled.v2.0.0-alpha.6Garrett D'Amore2025-10-05
| | | | | | Also, some instances nni_aio are changed to nng_aio. We think we want to harmonize some of these types going forward as it will reduce the need to include headers hopefully letting us get away with just "defs.h" in more places.
* TLS: eliminate more runtime ops vectorsGarrett D'Amore2025-06-30
|
* TLS: Configuration does not need to keep a reference to the engine.Garrett D'Amore2025-06-29
| | | | This may resolve a surprising NULL pointer dereference.
* TLS: fixes for test coverage and improved identification logging.Garrett D'Amore2025-06-22
|
* TLS: Remove support for dynamic engine initialization.Garrett D'Amore2025-06-21
| | | | | This saves some atomic lookups, and avoids possible races when the engine is not yet initialized or being torn down.
* tls: false is not a numberGarrett D'Amore2025-06-21

* Introduce DTLS transport for NNG.Garrett D'Amore2025-06-01
| | | | | | | | | | | | | This introduces a new experimental transport for DTLS, that provides encryption over UDP. It has a simpler protocol than the current UDP SP protocol (but we intend to fix that by making the UDP transport simpler in a follow up!) There are a few other fixes in the TLS layer itself, and in the build, that were needed to accomplish this work. Also there was an endianness bug in the UDP protocol handling, which is fixed here.
* AIO: Use nng_err for cancellation callback instead of int.Garrett D'Amore2025-04-27
| | | | | | This is part of our work to improve type safety/awareness, and also improve debugger support, for NNG error codes. There are still quite a few more but this should help.
* TLS: break up the TLS layer a bit to refactor for DTLS.Garrett D'Amore2025-04-27
| | | | | | | | | | | This allows us to break the assumption that the bottom half is TCP, or even an nng_stream, since the DTLS layer will use a totally different layer. Only nng_stream neeeds to support dial and listen. Also: UDP: Make the sockaddr arguments to open const. Also: Align the IPv6 address in the sockaddr (this allows for efficient 64-bit or even 128-bit operations on these values.)
* Fix typo in NNG_TLS_MAX_RECV_SIZEGarrett D'Amore2025-04-13
|
* api: fold TLS supplemental headers into nng.hGarrett D'Amore2025-01-04
|
* tls: use nni_aio_beginGarrett D'Amore2024-12-26
|
* streams: add explicit stop functionsGarrett D'Amore2024-12-12
| | | | | | | | | | | | This allows us to explicitly stop streams, dialers, and listeners, before we start tearing down things. This hopefully will be useful in resolving use-after-free bugs in http, tls, and websockets. The new functions are not yet documented, but they are nng_stream_stop, nng_stream_dialer_stop, and nng_stream_listener_stop. They should be called after close, and before free. The close functions now close without blocking, but the stop function is allowed to block.
* Remove all the get_ptr option accessors.Garrett D'Amore2024-11-24
| | | | | Temporarily we have removed access to the peer alt names, but that was never used and was not tested (it also didn't work with WolfSSL.)
* tls: add a mutual authentication testGarrett D'Amore2024-11-23
| | | | | | | | Also, make it clearer that TLS keys and certificates can only be set once on a configuration. (mbedTLS makes this confusing!) This mutual test is only fully validated on mbed, because wolfSSL seems to not properly validate this in many configurations.
* refactor initialization/finalizationGarrett D'Amore2024-11-11
| | | | | | | | | Applications must now call nng_init(), but they can supply a set of parameters optionally. The code is now safe for multiple libraries to do this concurrently, meaning nng_fini no longer can race against another instance starting up. The nni_init checks on all public APIs are removed now.
* websocket: Do not allow a listener or dialer to change TLS while runningGarrett D'Amore2024-11-09
| | | | This also covers a few test cases that we were missing.
* TLS configuration changed to use discret _set_tls and _get_tls functions.Garrett D'Amore2024-11-09
| | | | This is simpler, and more reliable than using socket options.
* Remove nng_stream_set function family.Garrett D'Amore2024-10-28
| | | | This was not really used or useful.
* tls: Remove the individual TLS configuration optionsGarrett D'Amore2024-10-28
| | | | | | | | This is a breaking change. TLS configuration changes are to be made using TLS configuration objects, and then set on a listener or dialer with NNG_OPT_TLS_CONFIG. This should be a bit less racy, and allows for simpler code.
* TLS: announce which engine we are using (in anticipation of newer TLS engines)Garrett D'Amore2024-07-22
|
* fixes #1846 Add support for TLS PSKGarrett D'Amore2024-07-21
| | | | | | This also adds an SP layer transport test for TLS, based on the TCP test but with some additions; this test does not cover all the edge cases for TLS, but it does at least show how to use it.
* [tls_common] finish conn lock in tls_reapMoi Ran2024-04-14
|
* fixes #1588 TLS should log errorsGarrett D'Amore2024-04-14
| | | | | This isn't complete, but it should go much further in assisting debugging TLS related errors.
* Add missing `nng_tls_config_hold` stub functionMarc Lasch2024-04-13
| | | | | | | | | | | Add the missing stub function implementation for `nng_tls_config_hold`. Fixes an error when loading the library and expecting to have this symbol available. The availability of the symbol can be checked with nm: ``` nm -D cmake-build-release/libnng.so.1.7.3 | grep nng_tls_config_hold ```
* fixes #1673 High CPU usage with TLSGarrett D'Amore2023-12-16
| | | | | | The aio for connections was meant to have an infinite sleep (no timeout), but was getting an initial value of zero, so we were spinning on accept.
* Get common name and subject alternative names of peer certificate (#1617)Christian Fischbach2023-02-08
| | | Co-authored-by: Christian Fischbach <cfischbach@mac.com>
* Use static initialization for lists and mutexes.Garrett D'Amore2021-12-05
| | | | | | This eliminates some run-time initialization, moving it to compile time. Additional follow up work will expand on this to simplify initialization and reduce the need for certain locks.
* Provide atomic pointer support.Garrett D'Amore2021-12-05
| | | | | This is initially used for TLS to make loading the engine pointer faster, eliminating a much more expensive lock operation.
* fixes #1478 mbedTLS 3.0 is not API compatible with 2.xGarrett D'Amore2021-08-09

* Fix typo in tls_common.c (#1412)Evgeny Ermakov2021-01-24
|
* fixes #1372 nni_reap could be smallerGarrett D'Amore2020-12-19
|
* fixes #1071 tran_chkopt can be cleaned upGarrett D'Amore2020-11-15
| | | | | | | | | | | | | | | | | This is a sweeping cleanup of the transport logic around options, and also harmonizes the names used when setting or getting options. Additionally, legacy methods are now moved into a separate file and can be elided via CMake or a preprocessor define. Fundamentally, the ability to set to transport options via the socket is deprecated; there are numerous problems with this and my earlier approaches to deal with this have been somewhat misguided. Further these approaches will not work with future protocol work that is planned (were some options need to be negotiated with peers at the time of connection establishment.) Documentation has been updated to reflect this. The test suites still make rather broad use of the older APIs, and will be converted later.
* Clean up some warnings.Garrett D'Amore2020-11-08
|
* fixes #1235 framing error in SSL/TLSGarrett D'Amore2020-07-26
| | | | | | This was first detected as a stack overrun, but in actuality the problem could have lead to corruption of TLS messages due to prematurely recording transmit completion.
* Tests for sending large amounts of data over NNG TLS streams.Garrett D'Amore2020-05-23
| | | | | This also starts the test framework NNG streams, so that we can test those more directly.
* fixes #1005 TLS 1.3 supportGarrett D'Amore2020-02-23
| | | | | | | | This introduces support for an external wolfSSL plugin, and generally creates the framework for pluggable TLS implementations. The wolfSSL engine is provided via an external module (git submodule), available either under a GPLv3 license or a commercial license.
* fixes #1094 Consider in-lining task and aioGarrett D'Amore2020-01-08
| | | | | This only does it for rep, but it also has changes that should increase the overall test coverage for the REP protocol
* fixes #948 TLS listener leaks underlying TCP stream listenerGarrett D'Amore2019-05-19
|
* fix #946 Use after free in TLSGarrett D'Amore2019-05-19
| | | | | This also introduces a more efficient reference counting usage based on atomics, rather than locks.
* fixes #872 create unified nng_stream APIGarrett D'Amore2019-02-16
| | | | | | | | | This is a major change, and includes changes to use a polymorphic stream API for all transports. There have been related bugs fixed along the way. Additionally the man pages have changed. The old non-polymorphic APIs are removed now. This is a breaking change, but the old APIs were never part of any released public API.
* fixes #839 TCP listener_start API should use constant sockaddrGarrett D'Amore2019-01-06
|
* fixes #847 Define public TLS APIGarrett D'Amore2019-01-06
