      [FAB-6381] Secure defaults for txsFilter · 53de0781
      Alessandro Sorniotti authored
      The aim of this change set is to apply the well-established "Secure by
      default" security principle to the way the validator validates transactions
      in a block.
      The current code behaves as follows: create an array of validation codes, set
      by default to "all transactions are valid"; then perform validation which may
      mark transactions as invalid. Furthermore, in other parts of the code, if no
      array of validation codes is yet persent in the block, a new one is
      indiscriminately created (again, marking all transactions as valid). This
      approach is a security anti-pattern because it opens up to attacks where an
      adversary may force the code through a path where the default "tx is valid"
      validation code is maintained even for invalid txes.
      This change set ensures that validation code arrays are created and set to a
      new value (TxValidationCode_NOT_VALIDATED) which ensures that a transaction
      that hasn't been validated cannot be mistaken for a valid one.

      [FAB-7497] validate txes against LSCC cc data · 0febaf8d
      Alessandro Sorniotti authored
      As per the original design of FAB-6042, the main repository for chaincode
      data was to be the resource tree. As a consequence, changes to both VSCC
      and the validator code were introduced to retrieve chaincode data from
      the resource tree and to use a policy pointer vs. policy literal in VSCC.
      According to FAB-7497 however, chaincode data is always
      stored in LSCC. This change set therefore removes the alternate code path.

      [FAB-5932] - Parallel tx validation · 9b6b8fe6
      Alessandro Sorniotti authored
      This change-set introduces parallelism on the committer. In particular, tx
      generic validation (e.g. well-formedness, signature checks) and VSCC validation
      are conducted in parallel for all transactions inside a block. This change-set
      scales the *validation* throughput with number of cores on the machine that
      runs the peer.

      [FAB-5654] SideDB - Tx simulation/validation/commit · 8a87b8ae
      manish authored
      This CR modifies the tranaction simulation, validation, and commit
      code and delivers the end-to-end transaction flow that treats the
      private data in a special manner. This CR mainly leverages the earlier
      submitted independent CRs for sidedb feature for accomplishing this behavior.
      This CR also allows ledger to receive the blocks and the pvt data from
      another peer on the same channel (i.e., a peer catching up via state)
      This CR is exceptionally large becasue of manily two reasons
      1) The way currently the code (and specially the tests) is organized in
      simulation/validation/commit flow, its not easy to submit such kind
      of changes independently that cuase the change in the whole transaction
      processing flow.
      2) This CR causes a change in the existing ledger APIs which are used widely
      across other packages (specially in the tests) and hence many files are included
      for fixing the broken dependencies

      [FAB-5353]: Qualify sys. failure vs validation error · 0cf4c35a
      Artem Barger authored
      Currently as stated in [FAB-5353], there is no clear separation during
      transaction validation during block commmit, between invalid transaction
      and some system failure which migh lead to inability to validate the
      transaction. For example db is down or file system is unavailable. This
      might lead to inconsistency of the state accross peers, therefore this
      commit takes care to distinguish between real case of invalid
      transaction versus system failure, later the error propagated down to
      the committer and forces peer to stop with panic, so admin will be able
      to take manual control and fix the problem therefore preventing peer
      state to diverge.

      [FAB-4591]Fix log message formatting · 4f882258
      Yuki Kondo authored
      Log formatting is not correct in some codes.
      There are log messages with format designator called by "Debug",
      "Warning" or "Info".
      These logging messages should be called by "Debugf", "Warningf"
      or "Infof".
      This patch fixes log formatting.

      [FAB-3330] validate chaincode version · f30fc741
      jiangyaoguo authored
      1. Add VsccOutputData struct to keep output of vscc.
      Vscc will return proposalResponsePayload(has verison info)
      bytes contained in ChaincodeAction.
      2. When committer validates transaction, check that the
      chaincode version in ProposalResponse matches the
      verision in lscc.
      3. Add new ValidateCode to distinguash two kinds of invalid
      reason because of chaincode upgrade.
      4. vsccValidatorImpl will return latest chaincodeInstance
      from lscc and vsccOutputData from vscc. So we can mock
      system chaincode in UT.
      5. Move ChaincodeInstance to sysccprovider to avoid
      cycle import.

      Will Lahti authored
      This CR updates all loggers throughout the code base to use
      `flogging.MustGetLogger`. This function wraps `logging.MustGetLogger`
      and tracks the logger modules defined in the system. This enables the
      ability to set log levels for modules using regular expressions.
      and make it easy to change the levels for any module and all its
      submodules with a single command (e.g. gossip, ledger, msp).

      This CR focuses on invalidating all transactions which
      are "invokes" to upgraded chaincodes in the same block.
      Invalid expired transactions in other blocks will be done

      for logic part to be tested easier.

      [FAB-3155] LSCC security checks at validation time · 735878b6
      Alessandro Sorniotti authored
      Invocations of LSCC need to undergo some common validation (e.g. that they
      are endorsed by as valid peer). Furthermore:
       - the instantiation policy should be satisfied
       - the read/write set should be coherent (e.g. it should only change the
         chaincode state whose instantiation policy is checked);
      This change-set refactors the validator code and prepares fabric for the
      two checks listed above, which will be delivered as a follow-up CS.

      Clean up peer logging - serviceability · b39b8a8f
      denyeart authored
      Clean up peer logging for improved serviceability.
      INFO level log had a lot of debug information, making it impossible
      to find important INFO information and errors through the noise.
      Changed most of the debug information to use DEBUG level.
      After this change, during normal transaction processing there
      will be a single entry in info log per block with messages
      like this:
      Channel [myc1]: Created block [1] with 43 transaction(s)
      Channel [myc1]: Created block [2] with 14 transaction(s)
      Channel [myc1]: Created block [3] with 26 transaction(s)
      This will make it easy to spot any anomilies in the logs, while
      still tracking block progress.
      Confirmed there are good INFO messages for important events
      such as peer initialization and channel creation.
      Removed data content from debug messages for enhanced privacy.

      [FAB-2243] Replace Tx Validation bit-array by flags · 29d7fc03
      Ruslan Kryukov authored
      Switch valid flag from a boolean to an enum, so that we can indicate the reason
      for the invalidation (txid already exists, vscc validation failure
      (endorsement policy failure), mvcc validation failure, etc)
      This change adds invalidation reason codes, sets them in the block as a uint8
      (byte) array, and returns validation result in GetTransactionById.

      This change set ensures that the protobuf representation for headers be in

      the serialized version we receive.
