* remove legacy support for configuration of transport options on socketGarrett D'Amore2024-10-20
| | | | | | | | | Transport specific options should be configured on the end point. This has the most impact for TLS, as TLS dialers and listeners will need to be allocated apriori, to configure TLS options. Some legacy tests were removed... we're going to remove the legacy libnanomsg compatibility layer anyway.
* Use `const` for nng_stat when possible.Garrett D'Amore2024-10-20
| | | | | This should help the compiler enforce checks, and may result in better optimizations.
* fixes #1890 stats could support an inline lock - remove most atomicsGarrett D'Amore2024-10-13
| | | | | This starts by updating UDP to use this approach, since we already have a convenient lock. We should look at doing the same for other stats.
* stats: Reduce some wasted space for disabled stats.Garrett D'Amore2024-10-13
| | | | | Unfortunately for now we have the struct itsel,f but it can become mostly empty.
* UDP: More test tuning for lossy environments.Garrett D'Amore2024-10-13
|
* udp: fix race, fix testsGarrett D'Amore2024-10-13
|
* UDP/sanitizer: Don't be strict about message loss in sanitizer or coverage runs.Garrett D'Amore2024-10-13
|
* UDP: burst testing to improve coverageGarrett D'Amore2024-10-13
| | | | | We are finding that on darwin its very easy for us to lose UDP messages as the socket buffer appears to be depressingly small.
* UDP: numerous fixes, added test for copy breakGarrett D'Amore2024-10-13
| | | | | | There were several bugs here, including use-after-free, a problem when the copy limit was exceeded, and uninitialized receive thresholds.
* UDP: add some statisticsGarrett D'Amore2024-10-12
|
* udp: fix leaks on EP destroyGarrett D'Amore2024-10-07
|
* Finally, actually register the UDP transport.Garrett D'Amore2024-10-07
|
* Actually enable UDP. Also fix some UWYI includes.Garrett D'Amore2024-10-06
|
* Remove the legacy transport registration functions.Garrett D'Amore2024-10-06
| | | | | | This also allows to remove most of the transport headers. Only zerotier.h sticks around, and only for now. (We expect to eject it into a separate module.)
* fixes #168 UDP transportGarrett D'Amore2024-10-05
| | | | | | | | | | | | | | | | This is the initial implementation of UDP transport. It does in order guarantees (and consequently filters duplicates), but it does not guarantee delivery. The protocol limits payloads to 65000 bytes (minus headers for SP), but you really want to keep it to much less -- probably best for short messages that within a single MTU to avoid IP fragmentation and reassembly. This is unicast only for now (although there are plans for some support for multicast and broadcast as well as being able to perform automatic mesh building, but that will be in following work. Additional tunables are coming. This is only lightly tested at this point, and should be considered experimental. Its also undocumented.
* TLS: make some tests conditional.Garrett D'Amore2024-07-22
| | | | This is in preparation for the wolfSSL integration.
* Fix conditional tls_tran_testGarrett D'Amore2024-07-21
|
* 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.
* Fixes problem that causing it unable to pass compile when ↵Peter Wang2024-06-01
| | | | | | NNG_TRANSPORT_ZEROTIER is enabled. It seems that there are typo in the struct type naming. And the wrong function name in `nni_sp_zt_register` that will cause link error.
* Free SP protocol streams before discarding aio objects.Garrett D'Amore2024-05-30
| | | | | | | | This seems to alleviate the use after free crashes, although it does not seem like it should. Current theory is that this closes the handle ensuring that it is unregistered from the I/O subsystem, thus preventing callbacks from firing and referring to objects that have been freed.
* Another attempt at the close deadlock, fix use-after-free.Garrett D'Amore2024-05-30
| | | | | | | | When closing pipes, we defer them to be reaped, but also leave them in the match list where they might be picked up by ep_match, or leak. It's best to reap these proactively and ensure that they are not allowed to life longer once they have errored during the negotiation phase.
* Logging improvements (#1816)Garrett D'Amore2024-04-21
| | | | | | | | | | | | * Add nng_str_sockaddr to get string representation of socket address. * Added nng_log_get_level() is meant to allow users to obtain the current level and avoid some possibly expensive operations just to collect debugging information when debugging is not in effect. We use a custom logger for NUTS, and this fits within the NUTS test framework well, so that if -v is supplied we get more content. All tests now get this by default.
* Log messages when peer sends too large message.Garrett D'Amore2024-04-17
| | | | | Also while here, remove unused sockaddr members from some structs. This should save a bit of memory for servers with a lot of conns.
* Log protocol connections rejected by protocol.Garrett D'Amore2024-04-14
|
* Log transports as they are initialized.Garrett D'Amore2024-04-14
|
* fixes #1496 Provide NNG_ENABLE_IPV6 option (disabled by default)Garrett D'Amore2024-02-25
| | | | | | | | | This also checks if the build system has the definitions for AF_INET6, which might help in some embedded IPv4 only settings. The resolver test is enhanced to include a check for IPv6 enabled in the kernel. IPv6 support is enabled by default, of course.
* Add support for socket:// in NUTS marry function.Garrett D'Amore2024-02-18
| | | | | This also adds a HUGE test for REP using socket so that we can discriminate failures that might exist using sockets instead of inproc.

* fixes #1740 Public ID hash APIGarrett D'Amore2023-12-29
| | | | | | | | | This includes a manual page documenting the entire set of functions in one step. The hash is 64-bit based for now, to be maximally flexible. An internal 32-bit convenience for the common internal use is also provided (not public). The public API includes a test suite.
* tcp and tls: setting recv max on endpoint does not change pipesGarrett D'Amore2023-12-29
| | | | | Again, this was racy code, and not well tested. Set this option before starting the endpoint if you need to be sure.
* ipc: changing ep receive max should not affect established pipesGarrett D'Amore2023-12-29
| | | | This code was not well tested, and is racy as well.
* ipc: refactor get peerid support to use common POSIX codeGarrett D'Amore2023-12-29
| | | | | This eliminates some code. A test is added as well, so this should help with coverage.
* fixes #1746 Create a new socket:// transport for socketpair() based connectionsGarrett D'Amore2023-12-29
| | | | | | | | | | | | | This transport only listens, and creates connections when the application calls setopt on the lister with NNG_OPT_SOCKET_FD, to pass a file descriptor. The FD is turned into an nng_stream, and utilized for SP. The protocol over the descriptor is identical to the TCP protocol (not the IPC protocol). The options for peer information are borrowed from the IPC transport, as they may be useful for these purposes. This includes a test suite and full documentation.
* fixes #1728 surveyor could be simplified to not use timerGarrett D'Amore2023-12-17

* minor comment fixes for survey_testGarrett D'Amore2023-12-17

* fixes #1663 Request/Reply Protocol Throughput and ScalabilityGarrett D'Amore2023-12-16
| | | | | | | | | | | | | | | This eliminates the req protocols use of nni_timer (and setting a single timer node per request. This was problematic because it devolves into O(n^2) as we wind up inserting timer nodes and having to scan the list for the timer node. The solution is to use a single scan - stop worrying about insertion, but instead use a coarse granularity timer (defaults to 1 second) for retries. Then do the O(n) scan just once per interval. A new option, NNG_OPT_REQ_RESENDTICK, can be used to change the tick interval for cases (like unit tests) where more fine grained timing is required.

* req: use nni_aio_completions - this is similar to #1523Garrett D'Amore2023-11-25
|
* fixes #1523 rare SEGV in sub nni_list_removeGarrett D'Amore2023-11-25
| | | | | | | | | | | | Credit goes to Wu Xuan (@willwu1217) for diagnosing and proposing a fix as part of #1695. This approach takes a revised approach to avoid adding extra memory, and it also is slightly faster as we do not need to update both pointers in the linked list, by reusing the reap node. As part of this a new internal API, nni_aio_completions, is introduced. In all likelihood we will be able to use this to solve some similar crashes in other areas of the code.
* fix: use ifdef for NNG_TEST_LIBMarco Casaroli2023-11-25
| | | | | | | In some places, we use ifdef, and others if. This normalizes for always using ifdef, so we can compile when this macro is not defined.

* Fixes for some security complaints.Garrett D'Amore2022-12-31
| | | | | | | None of these changes are actual security bugs, but GitHub's scanner reports false positives at Critical severity for them. (There are a number of complaints from that scanner, many of which we do not necessarily agree with.)
