* socket: rename nng_close to nng_socket_closeGarrett D'Amore2024-12-31
|
* websocket tests: more resilience against EADDRINUSEGarrett D'Amore2024-12-31
|
* udp: use a bounce buffer if we lack sendmsg or recvmsgGarrett D'Amore2024-12-29
| | | | | This includes checks to determine if those functions are present, and a test case to verify that scatter gather with UDP works.
* resolver: use explicit resolver item provided by callerGarrett D'Amore2024-12-28
| | | | | | This avoids the need to perform multiple allocations for dialing, eliminating additional potential failures. Cancellation is also made simpler and more perfectly robust.
* zerotier: removedGarrett D'Amore2024-12-26
| | | | | | | | | | All vestiges of ZeroTier have been removed. Also, as consequence, some binary values have changed (specifically the number of the address family used for NNG_AF_ABSTRACT.) We may create a new ZeroTier transport that makes use of lwIP to provide for ZeroTier and native host network coexistence, without requiring ZeroTier to participate in the native networking stack.
* fix for potential leaking connectionsGarrett D'Amore2024-12-26
|
* pipeline: use nni_aio_startGarrett D'Amore2024-12-26
|
* sub: remove some calls to nni_aio_beginGarrett D'Amore2024-12-26
|
* pair0: use nni_aio_startGarrett D'Amore2024-12-26
|
* pair1: use nni_aio_startGarrett D'Amore2024-12-26
|
* pub sub: use nni_aio_startGarrett D'Amore2024-12-26
|
* bus: use nni_aio_startGarrett D'Amore2024-12-26
| | | | | | The test needed a change to ensure that we do not trigger a debugging check (you cannot submit another job on an aio that you've been notified is stopped via NNG_ESTOPPED.)
* req rep: use nni_aio_startGarrett D'Amore2024-12-26
|
* survey protocol conversion to nni_aio_startGarrett D'Amore2024-12-26
|
* udp: more nni_aio_startGarrett D'Amore2024-12-26
|
* tls: use nni_aio_beginGarrett D'Amore2024-12-26
|
* udp: use nni_aio_startGarrett D'Amore2024-12-26
| | | | | | This also moves the close of the UDP socket later, to avoid a potential use after free while the aio's are still in-flight. Unfortunately we cannot unbind cleanly without a hard close.
* ipc: use nni_aio_startGarrett D'Amore2024-12-26
|
* tcp: use nni_aio_startGarrett D'Amore2024-12-26
|
* websocket: use nni_aio_startGarrett D'Amore2024-12-26
|
* inproc: use nni_aio_startGarrett D'Amore2024-12-26
|
* sockfd: convert to use nni_aio_startGarrett D'Amore2024-12-26
|
* aio: introduce NNG_ESTOPPEDGarrett D'Amore2024-12-26
| | | | | | | | | | | This error code results when an AIO is stopped permanently, as a result of nni_aio_close or nni_aio_stop. The associated AIO object cannot be used again. This discrimantes against a file being closed, or a temporary cancellation which might allow the aio to be reused. Consumers must check for this error status in their callbacks, and not resubmit an operation that failed with this error. Doing so, will result in an infinite loop of submit / errors.
* aio: introduce nni_aio_deferGarrett D'Amore2024-12-22
| | | | | | | | This will replace nni_aio_schedule, and it includes finishing the task if needed. It does so without dropping the lock and so is more efficient and race free. This includes some conversion of some subsystems to it.
* test: fix valgrind complaint about unitialized test data in ipc testGarrett D'Amore2024-12-22
|
* websocket: stop trying to accept once we're closedGarrett D'Amore2024-12-16
|
* tls: fix deadlock in error pathGarrett D'Amore2024-12-16
|
* transports: all transports use the new inline approachGarrett D'Amore2024-12-15
| | | | | | We can retire the old approach that used separate allocations, and all of the supporting code. This also gives us a more natural signature for the end point initializations.
* websocket transport: use inline SP objectsGarrett D'Amore2024-12-15
| | | | | | | | | This also fixes a possible race in the listener that may cause connections to be dropped incorrectly, if the connection arrives before the common layer has posted an accept request. Instead we save the connection and potentially match later, like we do for the other protocols that need to negotiate.
* tls transport: use inline SP structuresGarrett D'Amore2024-12-15
|
* tls transport: inline aiosGarrett D'Amore2024-12-15
|
* inproc: use inline data structures for SP blocksGarrett D'Amore2024-12-15
| | | | | The pair is still a separate allocation, but this overall does reduce the number of allocations as well as a failure paths.
* inproc: use nni_refcntGarrett D'Amore2024-12-15
|
* test: fix uninitialized complaint from tcp recv max testGarrett D'Amore2024-12-15
|
* ipc: remove unnecessary check for null msg in finiGarrett D'Amore2024-12-15
|
* tcp transport: use preallocated SP objectsGarrett D'Amore2024-12-15
| | | | This follows a pattern we started earlier with IPC.
* tcp transport: inline aios (eliminate failure paths)Garrett D'Amore2024-12-15
|
* 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.
* transports: all transports implement stop functionsGarrett D'Amore2024-12-11
| | | | | Add test cases ensuring that the transports implement all required functionality (entry points are not null).
* zerotier: implement ep stopGarrett D'Amore2024-12-11
|
* websocket: implement ep stop hereGarrett D'Amore2024-12-11
| | | | | While here renamed a couple of symbols to avoid conflation with the supplemental websocket functions of the same name.
* tls: implement ep stopGarrett D'Amore2024-12-11
|
* inproc: implement stub ep stopGarrett D'Amore2024-12-11
| | | | | | Inproc doesn't have any real need for action here, as it's simple, but the stub implementation will let us remove the check in the common code layer.
* tcp: implement ep stopGarrett D'Amore2024-12-11
|
* ipc transport: convert to using inline data structuresGarrett D'Amore2024-12-11
|
* udp: implement endpoint stop functionsGarrett D'Amore2024-12-11
|
* sockfd: implement endpoint stop functionsGarrett D'Amore2024-12-11
|
* endpoints: add transport ep stop functionsGarrett D'Amore2024-12-11
| | | | | | This should allow us to stop the endpoints early, without freeing them. This ensures that pipe creation has ended before we start tearing down pipes.
* windows ipc: significant refactorGarrett D'Amore2024-12-09
| | | | | | | | | | | This refactors a lot of the IPC code to hopefully address various hangs on shutdown, etc. The problem is that named pipes are not terrifically reliable when it comes to aborting ConnectNamedPipe. Additionally there were some logic errors in some of our code that left things rather brittle. Ultimately this all needs to be replaced with UNIX domain sockets which are superior in many ways.
* udp transport: convert to using inline pipes and endpointsGarrett D'Amore2024-12-08
| | | | | This allows us to eliminate some extra reference counting and reaping related complexity.
