From 320bc845b37e06a24b692b7bb6e2ea14b7851f69 Mon Sep 17 00:00:00 2001 From: moneromooo-monero Date: Sat, 21 Dec 2019 17:40:59 +0000 Subject: rpc: add --rpc-payment-allow-free-loopback This allows RPC coming from the loopback interface to not have to pay for service. This makes it possible to run an externally accessible RPC server for payment while also having a local RPC server that can be run unrestricted and payment free. --- src/rpc/core_rpc_server.cpp | 11 ++++++++++- src/rpc/core_rpc_server.h | 2 ++ 2 files changed, 12 insertions(+), 1 deletion(-) (limited to 'src/rpc') diff --git a/src/rpc/core_rpc_server.cpp b/src/rpc/core_rpc_server.cpp index 5b79310c6..8905688b0 100644 --- a/src/rpc/core_rpc_server.cpp +++ b/src/rpc/core_rpc_server.cpp @@ -153,6 +153,7 @@ namespace cryptonote command_line::add_arg(desc, arg_rpc_payment_address); command_line::add_arg(desc, arg_rpc_payment_difficulty); command_line::add_arg(desc, arg_rpc_payment_credits); + command_line::add_arg(desc, arg_rpc_payment_allow_free_loopback); } //------------------------------------------------------------------------------------------------------------------------------ core_rpc_server::core_rpc_server( @@ -163,6 +164,7 @@ namespace cryptonote , m_p2p(p2p) , m_was_bootstrap_ever_used(false) , disable_rpc_ban(false) + , m_rpc_payment_allow_free_loopback(false) {} //------------------------------------------------------------------------------------------------------------------------------ bool core_rpc_server::set_bootstrap_daemon(const std::string &address, const std::string &username_password) @@ -280,6 +282,7 @@ namespace cryptonote MERROR("Payments difficulty and/or payments credits are 0, but a payment address was given"); return false; } + m_rpc_payment_allow_free_loopback = command_line::get_arg(vm, arg_rpc_payment_allow_free_loopback); m_rpc_payment.reset(new rpc_payment(info.address, diff, credits)); m_rpc_payment->load(command_line::get_arg(vm, cryptonote::arg_data_dir)); m_p2p.set_rpc_credits_per_hash(RPC_CREDITS_PER_HASH_SCALE * (credits / (float)diff)); @@ -353,7 +356,7 @@ namespace cryptonote #define CHECK_PAYMENT_BASE(req, res, payment, same_ts) do { if (!ctx) break; uint64_t P = (uint64_t)payment; if (P > 0 && !check_payment(req.client, P, tracker.rpc_name(), same_ts, res.status, res.credits, res.top_hash)){return true;} tracker.pay(P); } while(0) #define CHECK_PAYMENT(req, res, payment) CHECK_PAYMENT_BASE(req, res, payment, false) #define CHECK_PAYMENT_SAME_TS(req, res, payment) CHECK_PAYMENT_BASE(req, res, payment, true) -#define CHECK_PAYMENT_MIN1(req, res, payment, same_ts) do { if (!ctx) break; uint64_t P = (uint64_t)payment; if (P == 0) P = 1; if(!check_payment(req.client, P, tracker.rpc_name(), same_ts, res.status, res.credits, res.top_hash)){return true;} tracker.pay(P); } while(0) +#define CHECK_PAYMENT_MIN1(req, res, payment, same_ts) do { if (!ctx || (m_rpc_payment_allow_free_loopback && ctx->m_remote_address.is_loopback())) break; uint64_t P = (uint64_t)payment; if (P == 0) P = 1; if(!check_payment(req.client, P, tracker.rpc_name(), same_ts, res.status, res.credits, res.top_hash)){return true;} tracker.pay(P); } while(0) //------------------------------------------------------------------------------------------------------------------------------ bool core_rpc_server::check_core_ready() { @@ -3255,4 +3258,10 @@ namespace cryptonote , "Restrict RPC to clients sending micropayment, yields that many credits per payment" , DEFAULT_PAYMENT_CREDITS_PER_HASH }; + + const command_line::arg_descriptor core_rpc_server::arg_rpc_payment_allow_free_loopback = { + "rpc-payment-allow-free-loopback" + , "Allow free access from the loopback address (ie, the local host)" + , false + }; } // namespace cryptonote diff --git a/src/rpc/core_rpc_server.h b/src/rpc/core_rpc_server.h index 3b8e9c20a..d82ab6af4 100644 --- a/src/rpc/core_rpc_server.h +++ b/src/rpc/core_rpc_server.h @@ -75,6 +75,7 @@ namespace cryptonote static const command_line::arg_descriptor arg_rpc_payment_address; static const command_line::arg_descriptor arg_rpc_payment_difficulty; static const command_line::arg_descriptor arg_rpc_payment_credits; + static const command_line::arg_descriptor arg_rpc_payment_allow_free_loopback; typedef epee::net_utils::connection_context_base connection_context; @@ -287,6 +288,7 @@ private: std::map m_host_fails_score; std::unique_ptr m_rpc_payment; bool disable_rpc_ban; + bool m_rpc_payment_allow_free_loopback; }; } -- cgit v1.2.3
