2012-09-13Avoid undefined behaviour when parsing HS protocol versionsRobert Ransom
Fixes bug 6827; bugfix on c58675ca728f12b42f65e5b8964ae695c2e0ec2d (when the v2 HS desc parser was implemented). Found by asn.

2012-08-09Don't infer we have a FooPort from the presence of a FooPort lineNick Mathewson
Thanks to the changes we started making with SocksPort and friends in 0.2.3.3-alpha, any of our code that did "if (options->Sockport)" became wrong, since "SocksPort 0" would make that test true whereas using the default SocksPort value would make it false. (We didn't actually do "if (options->SockPort)" but we did have tests for TransPort. When we moved DirPort, ORPort, and ControlPort over to the same system in 0.2.3.9-alpha, the problem got worse, since our code is littered with checks for DirPort and ORPort as booleans. This code renames the current linelist-based FooPort options to FooPort_lines, and adds new FooPort_set options which get set at parse-and-validate time on the or_options_t. FooPort_set is true iff we will actually try to open a listener of the given type. (I renamed the FooPort options rather than leave them alone so that every previous user of a FooPort would need to get inspected, and so that any new code that forgetfully uses FooPort will need fail to compile.) Fix for bug 6507.

2012-07-31Warn at parse time for routerstatus entry missing a microdesc consensusNick Mathewson
In 0.2.3.18-rc, we started warning on this case while building a list of missing microdescriptor digests. That turned out to spam the logs; instead let's warn at parse time. Partial fix for bug 6404.
2012-07-17Change all SMARTLIST_FOREACH loops of >=10 lines to use BEGIN/ENDNick Mathewson
The SMARTLIST_FOREACH macro is more convenient than BEGIN/END when you have a nice short loop body, but using it for long bodies makes your preprocessor tell the compiler that all the code is on the same line. That causes grief, since compiler warnings and debugger lines will all refer to that one line. So, here's a new style rule: SMARTLIST_FOREACH blocks need to be short.

2012-06-04Add about 60 more DOCDOC comments to 0.2.3Nick Mathewson
Also, try to resolve some doxygen issues. First, define a magic "This is doxygen!" macro so that we take the correct branch in various #if/#else/#endifs in order to get the right documentation. Second, add in a few grouping @{ and @} entries in order to get some variables and fields to get grouped together.

2012-05-10Fix O(n^2) performance when parsing a big pile of extrainfosNick Mathewson
We were doing an O(n) strlen in router_get_extrainfo_hash() for every one we tried to parse. Instead, have router_get_extrainfo_hash() take the length of the extrainfo as an argument, so that when it's called from extrainfo_parse_from_string(), it doesn't do a strlen() over the whole pile of extrainfos.

2012-04-19Make base64_decode in rend_parse_client_keys more foolproofNick Mathewson
In general, whenever we can, we should be doing base64_decode(buf, sizeof(buf), s, strlen(s)), and not base_64_decode(buf, expr1, s, expr2) where we hope that expr1 is a good name for the size of buf and expr2 is a good formula for the length of the base64 expression in s.

2012-01-25Allow 0.2.3.x clients to use 0.2.2.x bridges.Roger Dingledine
Previously the client would ask the bridge for microdescriptors, which are only supported in 0.2.3.x and later, and then fail to bootstrap when it didn't get the answers it wanted. Fixes bug 4013; bugfix on 0.2.3.2-alpha. The fix here is to revert to using normal descriptors if any of our bridges are known to not support microdescs. This is not ideal, a) because we'll start downloading a microdesc consensus as soon as we get a bridge descriptor, and that will waste time if we later get a bridge descriptor that tells us we don't like microdescriptors; and b) by changing our mind we're leaking to our other bridges that we have an old-version bridge. The alternate fix would have been to change we_use_microdescriptors_for_circuits() to ask if *any* of our bridges can support microdescriptors, and then change the directory logic that picks a bridge to only select from those that do. For people living in the future, where 0.2.2.x is obsolete, there won't be a difference. Note that in either of these potential fixes, we have risk of oscillation if our one funny-looking bridges goes away / comes back.

2011-10-11Stop using addr_port_lookup as an address splitting functionNick Mathewson
It's too risky to have a function where if you leave one parameter NULL, it splits up address:port strings, but if you set it, it does hostname resolution.
2011-10-11Fix names of functions that convert strings to addrsNick Mathewson
Now let's have "lookup" indicate that there can be a hostname resolution, and "parse" indicate that there wasn't. Previously, we had one "lookup" function that did resolution; four "parse" functions, half of which did resolution; and a "from_str()" function that didn't do resolution. That's confusing and error-prone! The code changes in this commit are exactly the result of this perl script, run under "perl -p -i.bak" : s/tor_addr_port_parse/tor_addr_port_lookup/g; s/parse_addr_port(?=[^_])/addr_port_lookup/g; s/tor_addr_from_str/tor_addr_parse/g; This patch leaves aton and pton alone: their naming convention and behavior is is determined by the sockets API. More renaming may be needed.

2011-08-30Use %f with printf-style formatting, not %lfNick Mathewson
For printf, %f and %lf are synonymous, since floats are promoted to doubles when passed as varargs. It's only for scanf that we need to say "%lf" for doubles and "%f" for floats. Apparenly, some older compilers think it's naughty to say %lf and like to spew warnings about it. Found by grarpamp.
2011-07-18Only use optimistic data with exits that support itNick Mathewson
This adds a little code complexity: we need to remember for each node whether it supports the right feature, and then check for each connection whether it's exiting at such a node. We store this in a flag in the edge_connection_t, and set that flag at link time.
2011-07-01Don't shadow parameters with local variablesNick Mathewson
This is a little error-prone when the local has a different type from the parameter, and is very error-prone with both have the same type. Let's not do this. Fixes CID #437,438,439,440,441.

2011-06-03Reject 128-byte keys that are not 1024-bitNick Mathewson
When we added the check for key size, we required that the keys be 128 bytes. But RSA_size (which defers to BN_num_bytes) will return 128 for keys of length 1017..1024. This patch adds a new crypto_pk_num_bits() that returns the actual number of significant bits in the modulus, and uses that to enforce key sizes. Also, credit the original bug3318 in the changes file.

2011-05-15Log descriptions of nodes, not just nicknames.Nick Mathewson
This patch introduces a few new functions in router.c to produce a more helpful description of a node than its nickame, and then tweaks nearly all log messages taking a nickname as an argument to call these functions instead. There are a few cases where I left the old log messages alone: in these cases, the nickname was that of an authority (whose nicknames are useful and unique), or the message already included an identity and/or an address. I might have missed a couple more too. This is a fix for bug 3045.
