commit 6aef89bda4800384eddf79e42d965c2b011acdb4 Author: Nick Mathewson <nickm@torproject.org> Date: Fri Jul 15 12:58:13 2011 -0400 Remove compare_addr_to_node_policy Instead, use compare_tor_addr_to_node_policy everywhere. One advantage of this is that compare_tor_addr_to_node_policy can better distinguish 0.0.0.0 from "unknown", which caused a nasty bug with microdesc users. --- src/or/circuitbuild.c | 2 +- src/or/circuituse.c | 12 +++++++----- src/or/connection_edge.c | 10 ++++++---- src/or/policies.c | 13 +------------ src/or/policies.h | 2 -- src/or/routerlist.c | 4 ++-- src/or/routerlist.h | 2 +- 7 files changed, 18 insertions(+), 27 deletions(-) diff --git a/src/or/circuitbuild.c b/src/or/circuitbuild.c index 4397aa5..f7d5524 100644 --- a/src/or/circuitbuild.c +++ b/src/or/circuitbuild.c @@ -2634,7 +2634,7 @@ node_handles_some_port(const node_t *node, smartlist_t *needed_ports) port = *(uint16_t *)smartlist_get(needed_ports, i); tor_assert(port); if (node) - r = compare_addr_to_node_policy(0, port, node); + r = compare_tor_addr_to_node_policy(NULL, port, node); else continue; if (r != ADDR_POLICY_REJECTED && r != ADDR_POLICY_PROBABLY_REJECTED) diff --git a/src/or/circuituse.c b/src/or/circuituse.c index 67677ef..460c41f 100644 --- a/src/or/circuituse.c +++ b/src/or/circuituse.c @@ -509,7 +509,7 @@ circuit_stream_is_being_handled(edge_connection_t *conn, ok = connection_ap_can_use_exit(conn, exitnode); } else { addr_policy_result_t r; - r = compare_addr_to_node_policy(0, port, exitnode); + r = compare_tor_addr_to_node_policy(NULL, port, exitnode); ok = r != ADDR_POLICY_REJECTED && r != ADDR_POLICY_PROBABLY_REJECTED; } if (ok) { @@ -1262,10 +1262,12 @@ circuit_get_open_circ_or_launch(edge_connection_t *conn, if (check_exit_policy) { if (!conn->chosen_exit_name) { struct in_addr in; - uint32_t addr = 0; - if (tor_inet_aton(conn->socks_request->address, &in)) - addr = ntohl(in.s_addr); - if (router_exit_policy_all_nodes_reject(addr, + tor_addr_t addr, *addrp=NULL; + if (tor_inet_aton(conn->socks_request->address, &in)) { + tor_addr_from_in(&addr, &in); + addrp = &addr; + } + if (router_exit_policy_all_nodes_reject(addrp, conn->socks_request->port, need_uptime)) { log_notice(LD_APP, diff --git a/src/or/connection_edge.c b/src/or/connection_edge.c index a4a77af..867bd7a 100644 --- a/src/or/connection_edge.c +++ b/src/or/connection_edge.c @@ -3193,11 +3193,13 @@ connection_ap_can_use_exit(edge_connection_t *conn, const node_t *exit) if (conn->socks_request->command == SOCKS_COMMAND_CONNECT && !conn->use_begindir) { struct in_addr in; - uint32_t addr = 0; + tor_addr_t addr, *addrp = NULL; addr_policy_result_t r; - if (tor_inet_aton(conn->socks_request->address, &in)) - addr = ntohl(in.s_addr); - r = compare_addr_to_node_policy(addr, conn->socks_request->port, exit); + if (tor_inet_aton(conn->socks_request->address, &in)) { + tor_addr_from_in(&addr, &in); + addrp = &addr; + } + r = compare_tor_addr_to_node_policy(addrp, conn->socks_request->port, exit); if (r == ADDR_POLICY_REJECTED) return 0; /* We know the address, and the exit policy rejects it. */ if (r == ADDR_POLICY_PROBABLY_REJECTED && !conn->chosen_exit_name) diff --git a/src/or/policies.c b/src/or/policies.c index 93cae76..40e5277 100644 --- a/src/or/policies.c +++ b/src/or/policies.c @@ -689,7 +689,7 @@ compare_tor_addr_to_addr_policy(const tor_addr_t *addr, uint16_t port, if (!policy) { /* no policy? accept all. */ return ADDR_POLICY_ACCEPTED; - } else if (tor_addr_is_null(addr)) { + } else if (addr == NULL || tor_addr_is_null(addr)) { tor_assert(port != 0); return compare_unknown_tor_addr_to_addr_policy(port, policy); } else if (port == 0) { @@ -1461,17 +1461,6 @@ short_policy_is_reject_star(const short_policy_t *policy) * <b>node</b>.
