- **fix deadlock in ospf route introducd by #958 **
- **use random peer id for foreign network entry, because ospf route algo need peer id change after peer info version reset. this may interfere route propagation and cause node residual**
- **allow multiple nodes broadcast same network ranges for subnet proxy**
- **bump version to v2.3.2**
this may fix following problem:
1. cpu 100% when large number of nodes in network.
2. high cpu usage when large number of foreign networks.
3. packet loss when new node enters/exits.
4. old routes not cleand and show as an obloleted entry.
Some devices have ipv6 but don't allow input connection, this patch add hole punching for these devices.
- **add v6 hole punch msg to udp tunnel**
- **send hole punch packet when do ipv6 direct connect**
This patch implements:
1. A dns server that handles .et.net. zone in local and forward all other queries to system dns server.
2. A dns server instance which is a singleton in one machine, using one specific tcp port to be exclusive with each other. this instance is responsible for config system dns and run the dns server to handle dns queries.
3. A dns client instance that all easytier instance will run one, this instance will try to connect to dns server instance, and update the dns record in the dns server instance.
this pr only implements the system config for windows. linux & mac will do later.
* optimize memory issues
1. introduce jemalloc support, which can dump current memory usage
2. reduce the GlobalEvent broadcaster memory usage.
3. reduce tcp & udp tunnel memory usage
TODO: if peer conn tunnel hangs, the unbounded channel of peer rpc
may consume lots of memory, which should be improved.
* select a port from 15888+ when port is 0
* support ipv6 stun
* show interface and public ip in cli node info
* direct conn should keep trying unless already direct connected
* peer should use conn with smallest latency
* deprecate ipv6_listener, use -l instead
this patch optimize the udp hole punch logic:
1. allow start punch hole before stun test complete.
2. add lock to symmetric punch, avoid conflict between concurrent hole punching task.
3. support punching hole for predictable nat4-nat4.
4. make backoff of retry reasonable
This patch removes Tarpc & Tonic GRPC and implements a customized rpc framework, which can be used by peer rpc and cli interface.
web config server can also use this rpc framework.
moreover, rewrite the public server logic, use ospf route to implement public server based networking. this make public server mesh possible.
* ✨ feat: version
Add display version information, incompatible with lower versions
* 🎈 perf: unknown
Unknown when there is no version number displayed
* ✨ feat: Display local nodes
Display local nodes, incompatible with lower versions
* correctly set mtu, and allow set mtu manually
* communicate between enc and non-enc should not panic
* allow loading cfg from file
* allow change file log level dynamically
