[tor/master] Refactor addressmap_match_superdomains and representation of wildcards
by nickm＠torproject.org 30 Nov '11

30 Nov '11

commit 69d16900aaf1d54b44d2b28514a09873154c63d3 Author: Nick Mathewson <nickm(a)torproject.org> Date: Thu Sep 8 11:54:24 2011 -0400 Refactor addressmap_match_superdomains and representation of wildcards In this new representation for wildcarded addresses, there are no longer any 'magic addresses': rather, "a.b c.d", "*.a.b c.d" and "*.a.b *.c.d" are all represented by a mapping from "a.b" to "c.d". we now distinguish them by setting bits in the addressmap_entry_t structure, where src_wildcard is set if the source address had a wildcard, and dst_wildcard is set if the target address had a wildcard. This lets the case where "*.a.b *.c.d" or "*.a.b c.d" remap the address "a.b" get handled trivially, and lets us simplify and improve the addressmap_match_superdomains implementation: we can now have it run in O(parts of address) rather than O(entries in addressmap). --- src/or/circuituse.c | 2 +- src/or/config.c | 24 ++++++++----- src/or/connection_edge.c | 80 ++++++++++++++++++++++++++++----------------- src/or/connection_edge.h | 3 +- src/or/control.c | 2 +- 5 files changed, 69 insertions(+), 42 deletions(-) diff --git a/src/or/circuituse.c b/src/or/circuituse.c index f7f080d..fc252c9 100644 --- a/src/or/circuituse.c +++ b/src/or/circuituse.c @@ -1676,7 +1676,7 @@ consider_recording_trackhost(const entry_connection_t *conn, addressmap_register(conn->socks_request->address, new_address, time(NULL) + options->TrackHostExitsExpire, - ADDRMAPSRC_TRACKEXIT); + ADDRMAPSRC_TRACKEXIT,0,0); } /** Attempt to attach the connection conn to circ, and send a diff --git a/src/or/config.c b/src/or/config.c index 1d42413..ef54dcb 100644 --- a/src/or/config.c +++ b/src/or/config.c @@ -4459,6 +4459,7 @@ config_register_addressmaps(const or_options_t *options) addressmap_clear_configured(); elts = smartlist_create(); for (opt = options->AddressMap; opt; opt = opt->next) { + int from_wildcard = 0, to_wildcard = 0; smartlist_split_string(elts, opt->value, NULL, SPLIT_SKIP_SPACE|SPLIT_IGNORE_BLANK, 2); if (smartlist_len(elts) < 2) { @@ -4476,27 +4477,32 @@ config_register_addressmaps(const or_options_t *options) goto cleanup; } - /* Remove leading asterisk in expressions of type: '*.example.com' */ - if (!strncmp(from,"*.",2)) - from++; - if (!strncmp(to,"*.",2)) - to++; + /* Detect asterisks in expressions of type: '*.example.com' */ + if (!strncmp(from,"*.",2)) { + from += 2; + from_wildcard = 1; + } + if (!strncmp(to,"*.",2)) { + to += 2; + to_wildcard = 1; + } - if (to[0] == '.' && from[0] != '.') { + if (to_wildcard && !from_wildcard) { log_warn(LD_CONFIG, "Skipping invalid argument '%s' to MapAddress: " "can only use wildcard (i.e. '*.') if 'from' address " - "uses wildcard also", to); + "uses wildcard also", opt->value); goto cleanup; } if (address_is_invalid_destination(to, 1)) { log_warn(LD_CONFIG, - "Skipping invalid argument '%s' to MapAddress", to); + "Skipping invalid argument '%s' to MapAddress", opt->value); goto cleanup; } - addressmap_register(from, tor_strdup(to), 0, ADDRMAPSRC_TORRC); + addressmap_register(from, tor_strdup(to), 0, ADDRMAPSRC_TORRC, + from_wildcard, to_wildcard); if (smartlist_len(elts) > 2) log_warn(LD_CONFIG,"Ignoring extra arguments to MapAddress."); diff --git a/src/or/connection_edge.c b/src/or/connection_edge.c index 284b320..f7b2411 100644 --- a/src/or/connection_edge.c +++ b/src/or/connection_edge.c @@ -789,12 +789,18 @@ connection_ap_detach_retriable(entry_connection_t *conn, * the configuration file, "1" for mappings set from the control * interface, and other values for DNS and TrackHostExit mappings that can * expire.) + * + * A mapping may be 'wildcarded'.

[arm/master] Monkey patch for ACS disabling
by atagar＠torproject.org 30 Nov '11

commit bd94f0f5ef5490a48828aebfd4c11e39111daaa9 Author: Damian Johnson <atagar(a)torproject.org> Date: Wed Nov 30 10:36:15 2011 -0800 Monkey patch for ACS disabling Making manual ACS disabling transparent to the rest of the interface by monkey patching the ord values of ACS entries to '+', '-', or '|'. This has the advantage that the rest of the arm interface doesn't need to be aware of this complication, however it doesn't address the builtin box() function usage, which still makes most dialogs render incorrectly. --- src/util/panel.py | 25 +++++-------------------- src/util/uiTools.py | 27 ++++++++++++++++++--------- 2 files changed, 23 insertions(+), 29 deletions(-) diff --git a/src/util/panel.py b/src/util/panel.py index c0c13d8..50ae2c0 100644 --- a/src/util/panel.py +++ b/src/util/panel.py @@ -23,8 +23,7 @@ FORMAT_TAGS = {"": (_noOp, curses.A_BOLD), "<h>": (_noOp, curses.A_STANDOUT)} for colorLabel in uiTools.COLOR_LIST: FORMAT_TAGS["<%s>" % colorLabel] = (uiTools.getColor, colorLabel) -CONFIG = {"features.acsSupport": True, - "log.panelRecreated": log.DEBUG} +CONFIG = {"log.panelRecreated": log.DEBUG} # prevents curses redraws if set HALT_ACTIVITY = False @@ -426,11 +425,7 @@ class Panel(): if self.win and self.maxX > x and self.maxY > y: try: drawLength = min(length, self.maxX - x) - - if CONFIG["features.acsSupport"]: - self.win.hline(y, x, curses.ACS_HLINE | attr, drawLength) - else: - self.addstr(y, x, "-" * drawLength, attr) + self.win.hline(y, x, curses.ACS_HLINE | attr, drawLength) except: # in edge cases drawing could cause a _curses.error pass @@ -450,12 +445,7 @@ class Panel(): if self.win and self.maxX > x and self.maxY > y: try: drawLength = min(length, self.maxY - y) - - if CONFIG["features.acsSupport"]: - self.win.vline(y, x, curses.ACS_VLINE | attr, drawLength) - else: - for i in range(drawLength): - self.addch(y + i, x, "|", attr) + self.win.vline(y, x, curses.ACS_VLINE | attr, drawLength) except: # in edge cases drawing could cause a _curses.error pass @@ -696,13 +686,8 @@ class Panel(): # draws box around the scroll bar self.vline(drawTop, drawLeft + 1, drawBottom - 1) - - if CONFIG["features.acsSupport"]: - self.addch(drawBottom, drawLeft + 1, curses.ACS_LRCORNER) - self.addch(drawBottom, drawLeft, curses.ACS_HLINE) - else: - self.addch(drawBottom, drawLeft + 1, "+") - self.addch(drawBottom, drawLeft, "-") + self.addch(drawBottom, drawLeft + 1, curses.ACS_LRCORNER) + self.addch(drawBottom, drawLeft, curses.ACS_HLINE) def _resetSubwindow(self): """ diff --git a/src/util/uiTools.py b/src/util/uiTools.py index 51f5fee..bc1fefe 100644 --- a/src/util/uiTools.py +++ b/src/util/uiTools.py @@ -338,15 +338,9 @@ def drawBox(panel, top, left, width, height, attr=curses.A_NORMAL): panel.vline(top + 1, left + width - 1, height - 2, attr) # draws the corners - if CONFIG["features.acsSupport"]: - panel.addch(top, left, curses.ACS_ULCORNER, attr) - panel.addch(top, left + width - 1, curses.ACS_URCORNER, attr) - panel.addch(top + height - 1, left, curses.ACS_LLCORNER, attr) - else: - panel.addch(top, left, "+", attr) - panel.addch(top, left + width - 1, "+", attr) - panel.addch(top + height - 1, left, "+", attr) - panel.addch(top + height - 1, left + width - 1, "+", attr) + panel.addch(top, left, curses.ACS_ULCORNER, attr) + panel.addch(top, left + width - 1, curses.ACS_URCORNER, attr) + panel.addch(top + height - 1, left, curses.ACS_LLCORNER, attr) def isSelectionKey(key): """ @@ -714,6 +708,21 @@ def _initColors(): global COLOR_ATTR_INITIALIZED, COLOR_IS_SUPPORTED if not COLOR_ATTR_INITIALIZED: + # hack to replace all ACS characters with '+' if ACS support has been + # manually disabled + if not CONFIG["features.acsSupport"]: + for item in curses.__dict__: + if item.startswith("ACS_"): + curses.__dict__[item] = ord('+') + + # replace a few common border pipes that are better rendered as '|' or + # '-' instead + + curses.ACS_SBSB = ord('|') + curses.ACS_VLINE = ord('|') + curses.ACS_BSBS = ord('-') + curses.ACS_HLINE = ord('-') + COLOR_ATTR_INITIALIZED = True COLOR_IS_SUPPORTED = False if not CONFIG["features.colorInterface"]: return
