BITCOIN

RPM Package and SELinux

There probably should be two separate SELinux policy modules for the two different ways Bitcoin Core is used.

• System Service bitcoind
  • Should have its datadir somewhere like %{_datadir}bitcoinsys/ which expands to /var/lib/bitcoinsys/
  • Config file %config(noreplace) %{_datadir}/bitcoinsys/bitcoin.conf with wallet disabled by default, but they could enable it with wallet=1 if they really want it.
  • With system username like: bitcoinsys
  • Wrapper should launch bitcoind in a context named like: bitcoinsys_t
  • %doc README-FEDORA-BITCOIN-SERVICE should probably explain how the service is meant to be configured, used and controlled with bitcoin-cli or RPC/REST interfaces as the non-default datadir does not match upstream documentation and it thus may be non-obvious to users.
• User service bitcoind and graphical bitcoin-qt
  • The most common way in which Bitcoin Core users run their own bitcoind or bitcoin-qt with is as a non-root user with datadir ~/.bitcoin/.
  • There should be a separate user homedir SELinux policy for bitcoind and bitcoin-qt operated in this manner, with a context like user_bitcoin_t.
  • Note: Arbitrary other services may need to be granted both UNIX filesystem and SELinux permission to read the autotoken file from the user's ~/.bitcoin directory.
