2022-08-02Change module name to go.fd.io/govppHEADv0.6.0-alphamasterNathan Skrzypczak10-32/+32
We are changing the module name from git.fd.io/govpp.git to go.fd.io/govpp to make repository migration easier. Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com> Change-Id: Idd6e0d583a92f6b82fe9adeffd026cd6b856038b
2022-05-30Update generated binapi to v22.02 & makefile changesNathan Skrzypczak2-41/+41
This patch does some small updates to the Makefile. * `make gen-binapi-from-code` is removed, and moves to `gen-binapi-local` * `make build` is patched to build cmd & examples * `make binapi-generator` to build the api-generator without other binaries, as they typically require its output to build. * `make gen-binapi-local` runs the locally built binapi-generator to update the local bindings. It expects ${VPP_DIR} to be set and to point to a local vpp repository checked out with the right version * `make gen-binapi-internal` runs the locally built binapi-generator to update the bindings in `internal/testbinapi/binapi2001` Regarding VPP, notable changes when moving to v22.02 are : - ControlPing moved from vpe to memclnt - CliInband went from vpe to vlib Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com> Change-Id: Ie5cd2d5ded7ecaffd9abc3ca675df40be272b1fa

2022-05-05fixed data race in core.Connection.Close().Sergey Elantsev2-5/+32
The problem is triggered by the following events: 1. VPP stops. 2. core.Connection.healthCheckLoop() detects it and calls disconnectVPP(), which does close healthCheckDone channel for the first time. At this point Connection becomes unusable - re-entrance to connectLoop() will return immediately because of a closed healthCheckDone channel. But, the race is that connection may set c.vppConnected = 1 before terminating the connect loop. 3. User calls Connection.Close(), who seed c.vppConnected = 1, and tries to close already closed channel, which leads to a panic. This commit fixes this race by telling disconnectVPP() whether it is a terminal stop triggered via Close(), or a temporary one from connectLoop().

2022-01-31connection: prevent channel ID overlapLukas Vogel3-11/+27
When creating a new channel and the channel ID wraps around, make sure to not re-use a channel ID that is still in use. Re-using the channel ID usually means that the connection health check will stop working and other things might break as well. Also rename maxChannelID to nextChannelID and use a lock to guard access instead of using an atomic. The lock does anyway need to be acquired because to put the entry in the map. This commit was inspired by the following PR on Github: https://github.com/FDio/govpp/pull/14. Change-Id: I8c1a4ca63a53d07a6482b6047a3005065168c0b4 Signed-off-by: Lukas Vogel <vogel@anapaya.net>
2021-10-19Fix memory leak in health checkVladimir Lavor1-51/+56
1. On connection disconnect, health check loop ends immediately and independently on probe interval setup 2. Proper resource cleanup On disconnect, health check terminates itself with a delay based on the probe interval. It causes memory usage going up if AsyncConnect() & Disconnect() are called in a loop.

2021-02-23Added asynchronous connection for stats socketVladimir Lavor1-22/+93

New method AsyncConnectStats returns a channel where notificaitons of type ConnectionEvent will be sent. Fixed the stats reconnect procedure which sometimes failed to re-eneable the connection.

2020-07-17Added VPP state 'NotResponding'Vladimir Lavor1-14/+30
This change allows informing client about the current VPP state in more detail. * In case the VPP is overloaded but keeps its configuration, client received 'NotResponding' event message * If the VPP process dies (the socket is closed), the client receives 'Disconnected' event message Additional fix: event messages are discarded if the buffer is full. This could cause GoVPP to hang after some time in case the client was not receiveing events. Change-Id: I94a4647f6643f1d97bf52e5d7996d70229b0577d Signed-off-by: Vladimir Lavor <vlavor@cisco.com>
