A prior change to address accidental DNS lookups introduced the
SocketAddr on peer, which was then used to add it to the addressbook.
Which in turn swallowed the self reported port of the peer, which is
important on a reconnect. This change revives the NetAddress on NodeInfo
which the Peer carries, but now returns an error to avoid nil
dereferencing another issue observed in the past. Additionally we could
potentially address #3532, yet the original problem statemenf of that
issue stands.
As a drive-by optimisation `MarkAsGood` now takes only a `p2p.ID` which
makes it interface a bit stricter and leaner.
* OriginalAddr -> SocketAddr
OriginalAddr records the originally dialed address for outbound peers,
rather than the peer's self reported address. For inbound peers, it was
nil. Here, we rename it to SocketAddr and for inbound peers, set it to
the RemoteAddr of the connection.
* use SocketAddr
Numerous places in the code call peer.NodeInfo().NetAddress().
However, this call to NetAddress() may perform a DNS lookup if the
reported NodeInfo.ListenAddr includes a name. Failure of this lookup
returns a nil address, which can lead to panics in the code.
Instead, call peer.SocketAddr() to return the static address of the
connection.
* remove nodeInfo.NetAddress()
Expose `transport.NetAddress()`, a static result determined
when the transport is created. Removing NetAddress() from the nodeInfo
prevents accidental DNS lookups.
* fixes from review
* linter
* fixes from review
* fix dirty data in peerset
startInitPeer before PeerSet add the peer,
once mconnection start and Receive of one
Reactor faild, will try to remove it from PeerSet
while PeerSet still not contain the peer. Fix
this by change the order.
* fix test FilterDuplicate
* fix start/stop race
* fix err
* close peer's connection to avoid fd leak
Fixes#2967
* rename peer#Addr to RemoteAddr
* fix test
* fixes after Ethan's review
* bring back the check
* changelog entry
* write a test for switch#acceptRoutine
* increase timeouts? :(
* remove extra assertNPeersWithTimeout
* simplify test
* assert number of peers (just to be safe)
* Cleanup in OnStop
* run tests with verbose flag on CircleCI
* spawn a reading routine to prevent connection from closing
* get port from the listener
random port is faster, but often results in

We are swapping the exisiting listener implementation with the newly
introduced Transport and its default implementation MultiplexTransport,
removing a large chunk of old connection setup and handling scattered
over the Peer and Switch code. The Switch requires a Transport now and
handles externally passed Peer filters.
Currently the top level directory contains basically all of the code
for the crypto package. This PR moves the crypto code into submodules
in a similar manner to what `golang/x/crypto` does. This improves code
organization.
Ref discussion: https://github.com/tendermint/tendermint/pull/1966Closes#1956
As both configs are concerned with the p2p packaage and PeerConfig is
only used inside of the package there is no good reason to keep the
couple of fields separate, therefore it is collapsed into the more
general P2PConifg. This is a stepping stone towards a setup where the
components inside of p2p do not have any knowledge about the config.
follow-up to #1325
To achieve faster feedback cycles for our feature PRs this change
reduces the average buildtime from 35 to ~6min by utilising their new
2.0 offering based on docker and nomad. We make use of parallel build
steps wherever possible so that the duration is determined by the
slowest test suite (p2p).
This is an intermediate step until we move our CI/CD completely
on-premise for more control and added security.
* expose AuthEnc in the P2P config
if AuthEnc is true, dialed peers must have a node ID in the address and
it must match the persistent pubkey from the secret handshake.
