* 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.
* 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
|
* 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.
* socket transport: convert to using inline pipe and endpoint allocationsGarrett D'Amore2024-12-08
| | | | | | | This eliminates the need for separate reap operations, and it also eliminates a few failure modes, further simplifying the code. This is the first transport to get this treatment. The others will follow.
* socket transport: No need for a cool down for this transport.Garrett D'Amore2024-12-07
| | | | | | If an error occurs, the application gets to know about it. There cannot be external factors that cause us to spin for memory, since this is not accessible via the network.
* tests: add sockfd test for multiple acceptsGarrett D'Amore2024-12-07
| | | | While here initialize the message to avoid valgrind complaints.
* websocket: inline the aiosGarrett D'Amore2024-12-07
| | | | This covers both the ttransport and the supplemental layers.
* udp: hang on close after sending too largeGarrett D'Amore2024-12-07
|
* inproc: add pipe stop.Garrett D'Amore2024-12-07
| | | | | This is not needed for this, but it is the only transport that does not have it, and adding it simplifies logic in the common code.
* tests: fix type mismatch on htonlGarrett D'Amore2024-11-30
|
* tests: convert ws transport test to NUTSGarrett D'Amore2024-11-30
|
* tests: convert TCPv6 transport test to NUTS (and consolidate with v4)Garrett D'Amore2024-11-30
|
* tests: tcp test converted to NUTSGarrett D'Amore2024-11-30
| | | | | TCPv6 not done yet since that needs special work to be conditionalized. Also tcpsupp remains to be converted.
* tests: inproc converted to NUTSGarrett D'Amore2024-11-30
| | | | | | | | This actually represents a conversion of the transport tests implemented in Convey terms to NUTS. As part of this, have implemented a simple round trip performance test, using PAIR. The rest of the transport tests will shortly be converted to this as well.
* sockfd: inline aio structsGarrett D'Amore2024-11-24
|
* tls: don't use an extra resolver step in the listener.Garrett D'Amore2024-11-24
| | | | This was centralized in the stream layer a while ago.
* sockfd: we can use NULL for dialer opsGarrett D'Amore2024-11-24
|
* Remove the NNG_OPT_IPC_SECURITY_DESCRIPTOR option.Garrett D'Amore2024-11-24
| | | | | | | | This is now replaced with nng_listener_set_security_descriptor and nng_stream_listener_set_security_descriptor functions. We may elect to remove these entirely, but for named pipe users they are probably still quite useful. Moving towards UNIX domain sockets would obsolete this functionality.
* ws: add some more test casesGarrett D'Amore2024-11-24
