The peer login expiration ACL check introduced in #714
filters out peers that are expired and agents receive a network map
without that expired peers.
However, the agents should see those peers in status "Disconnected".
This PR extends the Agent <-> Management protocol
by introducing a new field OfflinePeers
that contain expired peers. Agents keep track of those and display
then just in the Status response.
The ConnStatus is a custom type based on iota
like an enum. The problem was nowhere used to the
benefits of this implementation. All ConnStatus
instances has been compared with strings. I
suppose the reason to do it to avoid a circle
dependency. In this commit the separated status
package has been moved to peer package.
Remove unused, exported functions from engine
The Management gRPC API has too much business logic
happening while it has to be in the Account manager.
This also needs to make more requests to the store
through the account manager.
Code cleaning in the config.go of the client. This change keep the
logic in original state. The name of the exported function was not
covered well the internal workflow. Without read the comment was not
understandable what is the difference between the GetConfig and
ReadConfig. By the way both of them doing write operation.
Bug 1: When calculating the network map, peers added by a setup key
were falling under expiration logic while they shouldn't.
Bug 2: Peers HTTP API didn't return expired peers for non-admin users
because of the expired peer check in the ACL logic.
The fix applies peer expiration checks outside of the ACL logic.
When we delete a peer from an account, we save the account in the file store.
The file store maintains peerID -> accountID and peerKey -> accountID indices.
Those can't be updated when we delete a peer because the store saves the whole account
without a peer already and has no access to the removed peer.
In this PR, we dynamically check if there are stale indices when GetAccountByPeerPubKey
and GetAccountByPeerID.
Force to use the proper temp dir
If we do not define the configDir then the Go
create a random temp dir for copy routine.
It is not optimal from security purpose.
Goals:
Enable peer login expiration when adding new peer
Expire peer's login when the time comes
The account manager triggers peer expiration routine in future if the
following conditions are true:
peer expiration is enabled for the account
there is at least one peer that has expiration enabled and is connected
The time of the next expiration check is based on the nearest peer expiration.
Account manager finds a peer with the oldest last login (auth) timestamp and
calculates the time when it has to run the routine as a sum of the configured
peer login expiration duration and the peer's last login time.
When triggered, the expiration routine checks whether there are expired peers.
The management server closes the update channel of these peers and updates
network map of other peers to exclude expired peers so that the expired peers
are not able to connect anywhere.
The account manager can reschedule or cancel peer expiration in the following cases:
when admin changes account setting (peer expiration enable/disable)
when admin updates the expiration duration of the account
when admin updates peer expiration (enable/disable)
when peer connects (Sync)
P.S. The network map calculation was updated to exclude peers that have login expired.
Among other improvements, it fixes a memory leak with
srfx conn channels not being closed
it also make use of new pion/transport Net interface

Extend HTTP API with Account endpoints to configure global peer login expiration.
GET /api/accounts
PUT /api/account/{id}/
The GET endpoint returns an array of accounts with
always one account in the list. No exceptions.
The PUT endpoint updates account settings:
PeerLoginExpiration and PeerLoginExpirationEnabled.
PeerLoginExpiration is a duration in seconds after which peers' logins will expire.
Small code cleaning in the iface package. These changes necessary to
get a clean code in case if we involve more platforms. The OS related
functions has been distributed into separate files and it has been
mixed with not OS related logic. The goal is to get a clear picture
of the layer between WireGuard and business logic.
* Disable upstream DNS resolver after several tries and fails
* Add tests for upstream fails
* Use an extra flag to disable domains in DNS upstreams
* Fix hashing IPs of nameservers for updates.
This PR adds a peer login expiration logic that requires
peers created by a user to re-authenticate (re-login) after
a certain threshold of time (24h by default).
The Account object now has a PeerLoginExpiration
property that indicates the duration after which a peer's
login will expire and a login will be required. Defaults to 24h.
There are two new properties added to the Peer object:
LastLogin that indicates the last time peer successfully used
the Login gRPC endpoint and LoginExpirationEnabled that
enables/disables peer login expiration.
The login expiration logic applies only to peers that were created
by a user and not those that were added with a setup key.
