This commit add topic negotiation to the protocol.
On receiving a message from a client with version >= 1, we will generate
a shared key using Diffie-Hellman. We will record also which
installationID has sent us a message.
This key will be passed back to the above layer, which will then use to
start listening to a whisper topic (the `chat` namespace has no
knowledge of whisper).
When sending a message to a set of InstallationIDs, we check whether we
have agreed on a topic with all of them, and if so, we will send on this
separate topic, otherwise we fallback on discovery.
This change is backward compatible, as long as there is no downgrade of
the app on the other side.
A few changes:
* Factored out the DB in a separate namespace as now it is
being used by multiple services (TopicService and EncryptionService).
* Factored out multidevice management in a separate namespace
* Moved all the test to test the whole protoocl rather than just the encryption service
* Moved all the filter management in status-go
This commits adds support for postgres database.
Currently two fields are stored: the bloom filter and the topic.
Only the bloom filter is actually used to query, but potentially we will
use also the topic in the future, so easier to separate it now in order
to avoid a migration.
Change to support sending multiple bundles, as needed for group chats,
limit number of devices to 3 as already done in the UI and refresh
bundle daily.
This commit adds a list new table, installations, which is used to keep
track of which installation are active for a given identity key.
In general, we limit the number of installation that we keep
synchronized to 5, to avoid excessive usage of resources.
Any installation coming from our own identity, will have to be manually
enabled, otherwise we trust the other peer has correctly paired their
devices.
We use a timestamp to decide which installations to keep synchronized as
a logical clock would have make the creation of the bundle more
complicated, but this can always be converted to a logical clock at
later stages without breaking compatibility.
- Skipped keys
The purpose of limiting the number of skipped keys generated is to avoid a dos
attack whereby an attacker would send a large N, forcing the device to
compute all the keys between currentN..N .
Previously the logic for handling skipped keys was:
- If in the current receiving chain there are more than maxSkip keys,
throw an error
This is problematic as in long-lived session dropped/unreceived messages starts
piling up, eventually reaching the threshold (1000 dropped/unreceived
messages).
This logic has been changed to be more inline with signals spec, and now
it is:
- If N is > currentN + maxSkip, throw an error
The purpose of limiting the number of skipped keys stored is to avoid a dos
attack whereby an attacker would force us to store a large number of
keys, filling up our storage.
Previously the logic for handling old keys was:
- Once you have maxKeep ratchet steps, delete any key from
currentRatchet - maxKeep.
This, in combination with the maxSkip implementation, capped the number of stored keys to
maxSkip * maxKeep.
The logic has been changed to:
- Keep a maximum of MaxMessageKeysPerSession
and additionally we delete any key that has a sequence number <
currentSeqNum - maxKeep
- Version
We check now the version of the bundle so that when we get a bundle from
the same installationID with a higher version, we mark the previous
bundle as expired and use the new bundle the next time a message is sent
- Replace command line flags with `-c` config flag. Part of #1180
- Convert node config private keys to hex-encoded string versions.
- Remove `GenerateConfig` from library.
- Remove unused `FirebaseConfig` from library.
- Fix loading of `config/status-chain-genesis.json` in non-dev machines.
In the current codebase if you want to use different keys (or any
other configuration) for tests it is required to place them at a
certain path in static folder, bundle them with go-bindata and only
then run tests. This is simply unnecessary.
This commit instead directs loads configurations from file without
relying on go-bindata

* Update project to use Whisper v6. Part of #638
* Revert "Add patch to downgrade usage of Whisper v6 to v5 in some geth 1.8.1 vendor files. Part of #665" - this reverts commit 6aefb4c8fd02dbcfffac6b69e8bb22b13ef86b6b.
* Enable light mode on Whisper v6 for non-mail servers. Part of #638
* Fix race condition in whisperv6/peer.go. Part of #665 (PR already accepted upstream for 1.8.2)
* Update bootnode addresses in staticnodes.json. Part of #638
* Add `shh.lightclient` flag and tests for bloom filter setting logic. Part of #638
* Move MakeTestNodeConfig to utils. Part of #638
* Reduce PoW in `whisper_jail_test.go` to fix flaky test. Part of #638
Fix failing tests for users w/o access to the ACCOUNT_PASSWORD env variable. Disable e2e public network tests in Travis pull requests. Exclude lib dir from unit tests.
* Accounts are now encrypted with a strong passphrase.
* The encrypted passphrase is stored in .travis.yml
* Public testnet tests are now run after tests on a private net
1. A new private testing network (StatusChain) is introduced.
2. An example test case implemented (TestSendEtherOnStatusChainTx)
3. Genesis file added static/config/status-chain-genesis.json
Geth js commands coming through jail with a callback will now be executed truly asynchronously blocking jail only when an actual interaction with VM is performed.
Technically, it registers a new handler jeth.sendAsync which executes functions with callbacks asynchronously.
Changes include:
1. Send and SendAsync now use cell.VM instead of otto.Otto providing proper locking.
2. Unmarshalling in ExecuionPolicy.ExecuteWithClient is now done into var result interface{} instead of var result json.RawMessage because test case 0 of TestJailWhisper failed providing byte codes instead of 5.0.
3. Due to the asynchronous nature of web3 calls new weird timeouts in tests have been introduced. They may fail sometimes but I gave up trying to implement a more reliable and readable solution.
* static: updates Whisper test (to work with Geth 1.6.1)
* jail: VM persistence implemented
* jail: sendMessage/showSuggestions minor fixes (to be squashed)
* node: CHT and boot nodes auto-load implemented
* Replaced CHT data file from farazdagi's to tiabc's
* Rewrote config_test.go using testify having reduced it twice in size
* Increased SyncTime and panic timeout in tests
* Fixed test - remove go default test to testify/suite (#207)
* Add flag setup for RPCEnabled and add comment (#225)
* jail: register method handlers before running initial js in jail (#226)
* Console Jail Mod #179 (#228)
* Added ./statusd-data into .gitignore
* Increased log level for the test node from INFO to ERROR
* Add call to loop.Run to evaluate all setTimeout/setIntervals methods. (#208)
* Rebase onto geth1.6.7 (#232)
* Got back sync duration from 60s to 30s, updated bindata.go
