Security bug fixes

Consolidated Security Fixes for v2.0.10 (#10091)

  • Fix issue with account query db that could result in incorrect data or hung processes
  • Implement a Subjective CPU billing system that helps P2P and API nodes better respond to extreme network congestion

Note: These security fixes are relevant to all nodes on EOSIO blockchain networks.

Notes on Subjective CPU Billing

This system consists of two primary features: a subjective (node local) view of spent CPU resources that are not yet accounted for by the blockchain that allows individual nodes to predict what resource consumption will be and, a subjective penalty system to offset work done in service of erroneous or malicious transactions.

The subjective view of CPU resources will synchronize with the resources present in the blockchain as it discovers the true CPU billing for transactions it has already accounted for.

The system will also accumulate CPU resources spent on failing transactions that will not be relayed in a decaying "subjective penalty" which can protect the individual nodes from abusive actors while remaining tolerant to occasional mistakes.

Subjective billing defaults to active and can be disabled with the disable-subjective-billing configuration in config.ini or on the command line.
