* fixes #1323 stats framework is *way* to heavyGarrett D'Amore2020-11-11
| | | | | | This should reduce the amount of copying, and the overall size used by pipes and other objects quite a bit. (On my system, the sizeof nni_pipe shrank by 400 bytes, for example.)
* Remove left over function prototypes.Garrett D'Amore2020-11-10

* fixes #1041 Abstract socket address for IPCGarrett D'Amore2020-11-08
| | | | | | | | | | | | | | | | | | | | | | | | fixes #1326 Linux IPC could use fchmod fixes #1327 getsockname on ipc may not work This introduces an abstract:// style transport, which on Linux results in using the abstract socket with the given name (not including the leading NULL byte). A new NNG_AF_ABSTRACT is provided. Auto bind abstract sockets are also supported. While here we have inlined the aios for the POSIX ipc pipe objects, eliminating at least one set of failure paths, and have also performed various other cleanups. A unix:// alias is available on POSIX systems, which acts just like ipc:// (and is fact just an alias). This is supplied so that in the future we can add support for AF_UNIX on Windows. We've also absorbed the ipcperms test into the new ipc_test suite. Finally we are now enforcing that IPC path names on Windows are not over the maximum size, rather than just silently truncating them.
* fixes #1311 reduce wasted use for nni_aioGarrett D'Amore2020-10-31
| | | | | | | | | | fixes #1317 IPv6 listener get port is incorrect fixes #1319 Want symbolic service names This is phase 1 of reducing the memory foot-print of aios, and also of pipes. This removes the largest consumer the socket address information, from the aio, which was only used by a few consumers.
* fixes #1289 zerotier should have it's own copy of the id hashing codeGarrett D'Amore2020-08-16
| | | | | | | | | | | fixes #1288 id allocation can overallocate fixes #1126 consider removing lock from idhash This substantially refactors the id hash code, giving a cleaner API, and eliminating a extra locking as well as some wasteful allocations. The ZeroTier code has it's own copy, that is 64-bit friendly, as the rest of the consumers need only a simpler 32-bit API.
* fixes #960 NNG threads inherit application thread nameGarrett D'Amore2020-08-08
| | | | | | This also exposes an nng_thread_set_name() function for applications to use. All NNG thread names start with "nng:". Note that support is highly dependent on the operating system.
* fixes #1279 Add support for ws4:// and ws6:// style websocket urlsGarrett D'Amore2020-08-08
| | | | fixes #1277 FreeBSD errors due to bad v4 vs. v6 assumptions
* fixes #844 WebSocket wildcard host errorsGarrett D'Amore2020-07-27
| | | | | | | | | | fixes #1224 wss fails on IPV6 address This fixes bugs and inconsistencies in the way addresses are handled for HTTP (and consequently websocket). The Host: address line needs to look at numeric IPs and treat wildcards as if they are not specified, and needs to understand the IPv6 address format using brackets (e.g. [::1]:80).
* fix #1252jeikabu2020-06-16
| | | | - nng_msg_clear should only clear the message body and not the head. Add test to verify
* fixes #1230 NNG_OPT_RECONNMAXT zero does not prevent exponential back-offGarrett D'Amore2020-05-24
|
* fixes #1239 Use after free in tlsGarrett D'Amore2020-05-23
| | | | | Also, addressed a number of Clang-tidy complaints. Potential hangs in close addressed as well.
* fixes #1236 Deadlock triggered on nng_closeGarrett D'Amore2020-05-17
| | | | fixes #1219 nng_close occasionally hang on Windows
* fixes #1171 message header could be inlined in the message structureGarrett D'Amore2020-02-26
| | | | | This uses a maximum 64-byte header and should avoid allocations and cache misses, leading to a small performance boost overall.
* fixes #1202 More than 120 threads was started by NNGGarrett D'Amore2020-02-24
| | | | | | | | This introduces a new CMake option, NNG_MAX_TASKQ_THREADS, with a default value of 16. The number of taskq workers will generally be calculated as vcpu * 2. This new value, if not zero, sets an upper bound. Note that the value should be at least two, in order to ensure no deadlocks occur.
* 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.
* Fix typos in commentsEvgeny Ermakov2020-02-13

* fixes #1169 survey and xsurvey could use message cloningGarrett D'Amore2020-01-20
| | | | | | | | | | | fixes #1160 Consider limiting maximum hop count to 15 fixes #1098 Maximum maxTTL should be compile time defined This doesn't expose the max-MaxTTL in the CMakeList.txt -- there is really no reason anyone should be changing it. This does not yet inline the message header into the nni_msg_t, but it is my intention to do so soon, and eliminate most of the conditional cases for failure on inserting into the header.
* fixes #1156 Message cloning could help reduce copies a lotGarrett D'Amore2020-01-20
| | | | | | | | | | | | This introduces reference counting on messages to reduce the data copies. This should have a marked improvement when moving large messages through the system, or when publishing to many subscribers. For some transports, when using large messages, the copy time can be the dominant factor. Note that when a message is actually shared, inproc will still perform an extra copy in order to ensure that it can modify the headers. This will unfortunately always be the case with REQ, as the REQ protocol keeps a copy of the original message so it can retry.
* fixes #1145 nng_msg options should be removedGarrett D'Amore2020-01-19
|
* fixes #1132 Masking error in LMQ leads to corruptionGarrett D'Amore2020-01-12
|
* XREQ and others race on TTL.Garrett D'Amore2020-01-11
| | | | | | | | | | The TTL in these cases should have been atomic. To facilitate things we actually introduce an atomic int for convenience. We also introduce a convenience nni_msg_must_append_u32() and nni_msg_header_must_append_u32(), so that we can eliminate some failure tests that cannot ever happen. Combined with a new test for xreq, we have 100% coverage for xreq and more coverage for the other REQ/REP protocols.
* 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 #1117 task structures should be inlinedGarrett D'Amore2020-01-06
|
* fixes #1116 task_reap can be eliminatedGarrett D'Amore2020-01-05
|
* fixes #1096 inline all 16 iovs in aio (also consider reducing -- to 8?)Garrett D'Amore2020-01-04
| | | | fixes #1097 aio prov_data not used at all
* fixes #1105 pollable can be inlined, and use atomicsGarrett D'Amore2020-01-04
| | | | | This also introduces an nni_atomic_cas64 to help with lock-free designs. Some mechanical renaming was done in some of the protocols for spelling.
* fixes #1104 move allocation of protocol objects to common coreGarrett D'Amore2020-01-03
| | | | fixes #1103 respondent could inline backtrace
* fixes #1090 nni_strlcat is unusedGarrett D'Amore2020-01-02
|
* fixes #1083 Random number improvementsGarrett D'Amore2020-01-01
|
* Fixup a few codacy complaints.Garrett D'Amore2020-01-01
|
* fixes #1081 Use after free possible in statsGarrett D'Amore2020-01-01
| | | | | | | fixes #1080 Desire better way to access statistics for NNG objects We've also added a test that uses some of this, in order to verify that the req protocol rejects invalid peers.
* fixes #1075 WebSocket heap use after freeGarrett D'Amore2019-12-30
| | | | | This also introduces a new atomic boolean type, so we can use that to trigger whether we've added the HTTP handler or not.
* Fix compilation errors and warnings when NNG_ENABLE_STATS is OFFRobert Bielik2019-12-30
|
* fixes #1064 Potential deadlock in statistics codeGarrett D'Amore2019-12-29
| | | | | | | | fixes #1063 Include sanitizer runs in CI fixes #1068 Wssfile test sometimes fails with wrong error code While here, addressed a number of clang-tidy items, and some light cleanup of code we were already in.
* Silence a few clang-tidy complaints.Garrett D'Amore2019-12-29
|
* fixes #1051 nni_ntop is unusedGarrett D'Amore2019-12-27
|
* Address complaints found by lgtm.com.Garrett D'Amore2019-12-11
|
* fixes #1004 Warning found by clang --analyzeGarrett D'Amore2019-11-11
| | | | | It's possible for an empty chunk to have a NULL data pointer. Even when copying zero bytes, this makes clang somewhat unhappy.
* fixes #954 large message fails with no error messageGarrett D'Amore2019-07-17
| | | | | | This removes the default 1MB limit on maximum receive sizes. Applications intended for deployment in insecure or hostile environments should choose a sensible default for NNG_OPT_RECVMAXSZ.
* 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.
* Add uint64 to generated legacy nng_setopt_* functions.Cody Piersall2019-05-17
| | | | | | The functions nng_dialer_setopt_uint64 and nng_dialer_setopt_uint64 are declared in nng.h but not defined, causing errors at runtime of programs that expect them to be defined.
* Introduce nni_plat_printf()Garrett D'Amore2019-05-07
| | | | | This permits the stats dump to avoid some extra buffering, and resolves a complaint about possible format buffer overruns.
* fixes #934 idhash should be a bit more robustGarrett D'Amore2019-04-24
