2015-01-19Make check-spaces happier.Nick Mathewson
2015-01-19Add a bunch of new comments to explain connection_ap_rewrite{,_and_attach}Nick Mathewson
Also, do a little light refactoring to move some variable declarations around and make a few things const Also fix an obnoxious bug on checking for the DONE stream end reason. It's not a flag; it's a possible value or a variable that needs to be masked.
2015-01-12Begin writing unit tests for rewrite codeNick Mathewson
2015-01-10document rewrite_result_t and export for testingNick Mathewson
2015-01-02Bump copyright dates to 2015, in case someday this matters.Nick Mathewson
2014-10-28Add another year to our copyright dates.Nick Mathewson
Because in 95 years, we or our successors will surely care about enforcing the BSD license terms on this code. Right?
2014-04-02Unit tests for connection_edge_process_resolved_cellNick Mathewson
Also rename a function to be more accurate (resolve->resolved)
2014-04-02Look at all of a RESOLVED cell; not just the first answer.Nick Mathewson
Also, stop accepting the old kind of RESOLVED cells with no TTL fields; they haven't been sent since 0.1.1.6-alpha. This patch won't work without the fix to #10468 -- it will break DNSPorts unless they set the proper ipv4/6 flags on entry_connection_t.
2013-07-10Completely refactor how FILENAME_PRIVATE worksNick Mathewson
We previously used FILENAME_PRIVATE identifiers mostly for identifiers exposed only to the unit tests... but also for identifiers exposed to the benchmarker, and sometimes for identifiers exposed to a similar module, and occasionally for no really good reason at all. Now, we use FILENAME_PRIVATE identifiers for identifiers shared by Tor and the unit tests. They should be defined static when we aren't building the unit test, and globally visible otherwise. (The STATIC macro will keep us honest here.) For identifiers used only by the unit tests and never by Tor at all, on the other hand, we wrap them in #ifdef TOR_UNIT_TESTS. This is not the motivating use case for the split test/non-test build system; it's just a test example to see how it works, and to take a chance to clean up the code a little.

2013-01-08Bug 7691: Send a probe cell down certain types of circs.Mike Perry
In general, if we tried to use a circ for a stream, but then decided to place that stream on a different circuit, we need to probe the original circuit before deciding it was a "success". We also need to do the same for cannibalized circuits that go unused.
2012-11-14Add some missing doxygen for ipv6 exit codeNick Mathewson
2012-11-14Actually send back correctly-formed IPv6 CONNECTED cellsNick Mathewson
We had some old code to send back connected cells for IPv6 addresses, but it was wrong. Fortunately, it was also unreachable.
2012-11-14Revise the DNS subsystem to handle IPv6 exits.Nick Mathewson
Now, every cached_resolve_t can remember an IPv4 result *and* an IPv6 result. As a light protection against timing-based distinguishers for IPv6 users (and against complexity!), every forward request generates an IPv4 *and* an IPv6 request, assuming that we're an IPv6 exit. Once we have answers or errors for both, we act accordingly. This patch additionally makes some useful refactorings in the dns.c code, though there is quite a bit more of useful refactoring that could be done. Additionally, have a new interface for the argument passed to the evdns_callback function. Previously, it was just the original address we were resolving. But it turns out that, on error, evdns doesn't tell you the type of the query, so on a failure we didn't know whether IPv4 or IPv6 queries were failing. The new convention is to have the first byte of that argument include the query type. I've refactored the code a bit to make that simpler.
2012-11-14Whitespace cleanupNick Mathewson
2012-11-14Get the client side of receiving an IPv6 address to workNick Mathewson
This makes it so we can handle getting an IPv6 in the 3 different formats we specified it for in RESOLVED cells, END_STREAM_REASON_EXITPOLICY cells, and CONNECTED cells. We don't cache IPv6 addresses yet, since proposal 205 isn't implemented. There's a refactored function for parsing connected cells; it has unit tests.
2012-11-14Add an IPv6Exit configuration optionNick Mathewson
Don't advertise an IPv6 exit policy, or accept IPv6 exit requests, if IPv6Exit is not true.
2012-11-14Refactor begin cell parsing into its own function, with tests.Nick Mathewson
Add 'flags' argument to begin cells, per proposal 208.
2012-11-14Move address map into its own file.Nick Mathewson
2012-10-12Rename all reserved C identifiers we definedNick Mathewson
For everything we declare that starts with _, make it end with _ instead. This is a machine-generated patch. To make it, start by getting the list of reserved identifiers using: git ls-tree -r --name-only HEAD | grep '\.[ch]$' | \ xargs ctags --c-kinds=defglmpstuvx -o - | grep '^_' | \ cut -f 1 | sort| uniq You might need gnu ctags. Then pipe the output through this script: ============================== use strict; BEGIN { print "#!/usr/bin/perl -w -i -p\n\n"; } chomp; next if ( /^__attribute__/ or /^__func__/ or /^_FILE_OFFSET_BITS/ or /^_FORTIFY_SOURCE/ or /^_GNU_SOURCE/ or /^_WIN32/ or /^_DARWIN_UNLIMITED/ or /^_FILE_OFFSET_BITS/ or /^_LARGEFILE64_SOURCE/ or /^_LFS64_LARGEFILE/ or /^__cdecl/ or /^__attribute__/ or /^__func__/ or /^_WIN32_WINNT/); my $ident = $_; my $better = $ident; $better =~ s/^_//; $better = "${better}_"; print "s/(?<![A-Za-z0-9_])$ident(?![A-Za-z0-9_])/$better/g;\n"; ============================== Then run the resulting script on all the files you want to change. (That is, all the C except that in src/ext.) The resulting script was: ============================== s/(?<![A-Za-z0-9_])_address(?![A-Za-z0-9_])/address_/g; s/(?<![A-Za-z0-9_])_aes_fill_buf(?![A-Za-z0-9_])/aes_fill_buf_/g; s/(?<![A-Za-z0-9_])_AllowInvalid(?![A-Za-z0-9_])/AllowInvalid_/g;

2012-05-14MSVC build issue: make 'const' in declaration match 'const' in definitionNick Mathewson
MSVC warns if you declare a function as having a "int foo" argument and then implement it with a "const int foo" argument, even though the latter "const" is not a part of the function's interface.
2012-05-11An attempt at bug3940 and making AllowDotExit 0 work with MapAddressNick Mathewson
This time, I follow grarpamp's suggestion and move the check for .exit+AllowDotExit 0 to the top of connection_ap_rewrite_and_attach, before any rewriting occurs. This way, .exit addresses are forbidden as they arrive from a socks connection or a DNSPort request, and not otherwise. It _is_ a little more complicated than that, though. We need to treat any .exit addresses whose source is TrackHostExits as meaning that we can retry without that exit. We also need to treat any .exit address that comes from an AutomapHostsOnResolve operation as user-provided (and thus forbidden if AllowDotExits==0), so that transitioning from AllowDotExits==1 to AllowDotExits==0 will actually turn off automapped .exit addresses.
2011-11-30Refactor addressmap_match_superdomains and representation of wildcardsNick Mathewson
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).

2011-07-19Implement sensible isolation for tunneled directory connsNick Mathewson
One-hop dirconn streams all share a session group, and get the ISO_SESSIONGRP flag: they may share circuits with each other and nothing else. Anonymized dirconn streams get a new internal-use-only ISO_STREAM flag: they may not share circuits with anything, including each other.
2011-07-19Launch sufficient circuits to satisfy pending isolated streamsNick Mathewson
Our old "do we need to launch a circuit for stream S" logic was, more or less, that if we had a pending circuit that could handle S, we didn't need to launch a new one. But now that we have streams isolated from one another, we need something stronger here: It's possible that some pending C can handle either S1 or S2, but not both. This patch reuses the existing isolation logic for a simple solution: when we decide during circuit launching that some pending C would satisfy stream S1, we "hypothetically" mark C as though S1 had been connected to it. Now if S2 is incompatible with S1, it won't be something that can attach to C, and so we'll launch a new stream. When the circuit becomes OPEN for the first time (with no streams attached to it), we reset the circuit's isolation status. I'm not too sure about this part: I wanted some way to be sure that, if all streams that would have used a circuit die before the circuit is done, the circuit can still get used. But I worry that this approach could also lead to us launching too many circuits. Careful thought needed here.

2011-07-19(Unused) backend logic for stream isolationNick Mathewson
This patch adds fields to track how streams should be isolated, and ensures that those fields are set correctly. It also adds fields to track what streams can go on a circuit, and adds functions to see whether a streams can go on a circuit and update the circuit accordingly. Those functions aren't yet called.

2011-04-27revert most of ef81649d2fcRoger Dingledine
Now we believe it to be the case that we never build a circuit for our stream that has an unsuitable exit, so we'll never need to use such a circuit. The risk is that we have some code that builds the circuit, but now we refuse to use it, meaning we just build a bazillion circuits and ignore them all.
2011-04-26When there is a transition in permitted nodes, apply it to trackexithosts mapNick Mathewson
IOW, if we were using TrackExitHosts, and we added an excluded node or removed a node from exitnodes, we wouldn't actually remove the mapping that points us at the new node. Also, note with an XXX022 comment a place that I think we are looking at the wrong string.

2010-10-01Initial conversion to use node_t throughout our codebase.Nick Mathewson
A node_t is an abstraction over routerstatus_t, routerinfo_t, and microdesc_t. It should try to present a consistent interface to all of them. There should be a node_t for a server whenever there is * A routerinfo_t for it in the routerlist * A routerstatus_t in the current_consensus. (note that a microdesc_t alone isn't enough to make a node_t exist, since microdescriptors aren't usable on their own.) There are three ways to get a node_t right now: looking it up by ID, looking it up by nickname, and iterating over the whole list of microdescriptors. All (or nearly all) functions that are supposed to return "a router" -- especially those used in building connections and circuits -- should return a node_t, not a routerinfo_t or a routerstatus_t. A node_t should hold all the *mutable* flags about a node. This patch moves the is_foo flags from routerinfo_t into node_t. The flags in routerstatus_t remain, but they get set from the consensus and should not change. Some other highlights of this patch are: * Looking up routerinfo and routerstatus by nickname is now unified and based on the "look up a node by nickname" function. This tries to look only at the values from current consensus, and not get confused by the routerinfo_t->is_named flag, which could get set for other weird reasons. This changes the behavior of how authorities (when acting as clients) deal with nodes that have been listed by nickname. * I tried not to artificially increase the size of the diff here by moving functions around. As a result, some functions that now operate on nodes are now in the wrong file -- they should get moved to nodelist.c once this refactoring settles down. This moving should happen as part of a patch that moves functions AND NOTHING ELSE. * Some old code is now left around inside #if 0/1 blocks, and should get removed once I've verified that I don't want it sitting around to see how we used to do things. There are still some unimplemented functions: these are flagged with "UNIMPLEMENTED_NODELIST()." I'll work on filling in the implementation here, piece by piece. I wish this patch could have been smaller, but there did not seem to be any piece of it that was independent from the rest. Moving flags forces many functions that once returned routerinfo_t * to return node_t *, which forces their friends to change, and so on.
