2020-09-22Reload stats socket when VPP restartsVladimir Lavor1-25/+100
The current implementation loads the stats socket and maps it to the memory. If VPP restarts, the socket file is recreated while the mapped data remain unchanged, silently failing since it does not get any updates. This change adds socket file monitoring which reconnects and remaps the socket file in such a case.

2020-09-02fixed data race in mock vpp adapterSergey Elantsev1-1/+4
There was a race in reading VppAdapter.mode in SendMsg and writing in MockReply/MockReplyHandler/MockReplyWithContext. All these *Reply* methods hold VppAdapter.repliesLock, so this fix uses this lock to safely read the value of a mode field.

2020-07-14socket adapter: don't bother sending sockclnt_delete messagesDave Barach1-45/+2
vpp cleans up socket clients when the socket closes. I verified that sending a correctly-marshalled sockclnt_delete message results in duplicate close complaints. The marshalling code wasn't right - the (important) client_index field is in a non-standard position - and there's no point in sending a message we don't need to send.
