b4e96778bf [CORDA-2517] Whitelist attachments signed by keys that already sign existing trusted attachments (#5068)
This allows a different signed version of the same CorDapp to be automatically trusted.

This reverts "[CORDA-2575] Allow users to whitelist attachments by public key config (#5035)"

cb85dd1e92 CORDA-2477 Improve Signature Constraints documentation (#5041)
The Signature Constraint documentation in `api-contract-constraints`
was very limited and referred to the design doc for most information.
Information was extracted from the design doc and added to the main
documentation.

[CORDA-2487] Provide a migration for vault states when moving from V3 to V4.1 (#4699)
* Create a new custom migration for populating the state_party table and the relevancy_status column within the vault_states table when migrating from V3 to V4.

* Add a corresponding unit test suite.

* Small refactorings to expose data required by the migration: the isRelevant function in the NodeVaultService, and the node's legal name from the configuration.

02645f7b9e Rework package namespace ownership check to verify every package of every class file.
Previous implementation was in LedgerTransaction and focused only on contract classes,
but every package matters.

Also fixes some exception types and does misc refactorings.

CORDA-2467: Moved non-contract things out of finance-contracts and into finance-workflows (#4700)
This includes all of the cash selection logic, JSON support using jackson and a bunch of utilities which are not relevant to contract verification. The exception to this are Interpolator which has been moved to the IRS demo, and PhysicalLocationStructures.kt which is now in explorer.

CORDA-2375 Ensure node has unique attachment contract classname/version from signed JARs (#4535)
Corda Node ensures a given contract class and version can be sourced from only one signed and trusted Attachment (JAR).
An attempt to import a signed JAR as a trusted uploader (or promote to be trusted) with a class and version already present in the other trusted Attachment will raise DuplicateContractClassException.

Minor fixes to Hibernate Attachment Query parser (original query to select attachment without signers would always return no attachments)

Fixed incorrect attachment loading integration test (#4453)
* Fixed incorrect attachment loading integration test

`AttachmentLoadingTests.test that attachments retrieved over the network are not used for code` was a false-positive - it was incorrect on multiple levels. Fixing it required updating the finance:isolated CorDapp, at which point it was given the new MANIFEST metadata for V4, and moved out of the net.corda.finance namespace to avoid package sealing issues.

The new test exposed a bug in the LedgerTransaction verification logic. This was cleaned up as it was too easy to verify on the wrong instance.

CORDA-2150 signature constraints non-downgrade rule (#4262)
Contract class version non-downgrade rule is check by LedgerTransaction.verify().
TransactionBuilder.toWireTransaction(services: ServicesForResolution) selects attachments for the transaction which obey non downgrade rule.
New ServiceHub method loadAttachmentConstraint(stateRef: StateRef, forContractClassName: ContractClassName? = null) retrieves the attachment contract related to transaction output states of given contract class name.

838c99c6e4 CORDA-2115: Notary whitelist verification changes (#4293)
* CORDA-2115: Notary whitelist verification changes

- For regular and contract upgrade transactions: check that the notary is in the network parameter whitelist
- For notary change transactions: check the the new notary is in the network parameter whitelist. This enabled support for network merging: the old notary doesn't have to be in the current network's notary whitelist for re-pointing old states to another notary.

These checks are done during transaction construction/verification and also by the non-validating notary.

* Address comments

* Remove stale todo

* Use notary whitelist of current network parameters for platform versoin 3

* Cleanup test

* Move `getHistoricNotary` to `HistoricNetworkParameterStorage` in `core.internal`

* Require `newNotary` to be notary on the network map during notary change

CORDA-2089 - network parameters tags - part (#4228)
* CORDA-2089 - network parameters tags - part

Data structures changes, storage and notarisation.

Tag transactions with network parameters hash that was in force when tx
was created. Add component group on all core transactions and resolved
parameters on full transactions. The hash should be always visible on
the filtered versions of transactions. Add
notarisation check that the parameters are current.
Implement network parameters storage on services for resolution.

This is only part of the work, next PR will include changes to
ResolveTransactionsFlow to make sure that parameters in the transaction
graph are ordered (this is to prevent the downgrade attack, when the
malicious notary and participants sign transaction that shouldn't be
notarised otherwise).
Probably on network services side we need the default parameters
endpoint for the
transactions that were created before this change - for now it's default
to the current ones.

* Make parameters storage agnostic to cert hierarchy

LedgerTransaction no longer a data class to prevent more copy methods and fixed serialisation issue (CORDA-2231) (#4287)
LedgerTransaction is not meant to be created directly from client code, but it being a data class means we will expose new copy methods as new properties are added. The existing copy methods that we've exposed since V3 are deprecated, and equals and hashCode have been updated to be based just on id.

The primary c'tor has been clearly marked as the class' wire format, and so the internal stuff has been moved out. The references property cannot be made nullable and so DeprecatedConstructorForDeserialization is used instead.
