| | * | | Be more robust when excluding existing nodes as new dirguardsNick Mathewson2013-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In addition to rejecting them post-hoc, avoid picking them in the first place. This makes us less likely to decide that we can't add guards at all.

* | | | get rid of the new caching notion in resolve_my_address()Roger Dingledine2013-02-12
| | | | | | | | | | | | | | | | and replace it with the good old-fashioned two functions approach

|/ / / | | | | | | | | | I didn't make any of the callers use this feature yet.
* | / Refactor resolve_my_address() so logs are more accurate / helpfulRoger Dingledine2013-02-11
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | It returns the method by which we decided our public IP address (explicitly configured, resolved from explicit hostname, guessed from interfaces, learned by gethostname). Now we can provide more helpful log messages when a relay guesses its IP address incorrectly (e.g. due to unexpected lines in /etc/hosts). Resolves ticket 2267. While we're at it, stop sending a stray "(null)" in some cases for the server status "EXTERNAL_ADDRESS" controller event. Resolves bug 8200.
* | Rename and relocate the bw weight scale param getter.Mike Perry2013-02-01
| | | | | | | | It had nothing to do with circuit build times.
* | Rename log() to tor_log() for loggingNick Mathewson2013-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | This is meant to avoid conflict with the built-in log() function in math.h. It resolves ticket 7599. First reported by dhill. This was generated with the following perl script: #!/usr/bin/perl -w -i -p s/\blog\(LOG_(ERR|WARN|NOTICE|INFO|DEBUG)\s*,\s*/log_\L$1\(/g; s/\blog\(/tor_log\(/g;
* | Add a function to compute fraction of nodes (by weighted bw) with descriptorsNick Mathewson2013-01-30

* | Split smartlist_choose_node_by_bandwidth_weightsNick Mathewson2013-01-18
| | | | | | | | | | | | This is a minimal refactoring to expose the weighted bandwidth calculations for each node so I can use them to see what fraction of nodes, weighted by bandwidth, we have descriptors for.

| * | Wrangle curve25519 onion keys: generate, store, load, publish, republishNick Mathewson2013-01-02
| | | | | | | | | | | | | | | | | | | | | | | | Here we try to handle curve25519 onion keys from generating them, loading and storing them, publishing them in our descriptors, putting them in microdescriptors, and so on. This commit is untested and probably buggy like whoa
* | | When there are no dir_server_ts to choose, don't crashNick Mathewson2012-12-18
| | | | | | | | | | | | | | | | | | | | | | | | It's important not to call choose_array_element_by_weight and then pass its return value unchecked to smartlist_get : it is allowed to return -1. Fixes bug 7756; bugfix on 4e3d07a6 (not in any released Tor)
* | | Avoid a 'may be used uninitialized' warningNick Mathewson2012-12-17
| | | | | | | | | | | | Fixes bug 7746; bug not in any released version of Tor.
* | | Nuke uses of memcmp outside of unit testsNick Mathewson2012-12-13
| | | | | | | | | | | | | | | | | | | | | We want to be saying fast_mem{cmp,eq,neq} when we're doing a comparison that's allowed to exit early, or tor_mem{cmp,eq,neq} when we need a data-invariant timing. Direct use of memcmp tends to imply that we haven't thought about the issue.

* | | New FallbackDir option to add extra directories for bootstrapingNick Mathewson2012-12-06
| | | | | | | | | | | | | | | | | | This replaces the old FallbackConsensus notion, and should provide a way -- assuming we pick reasonable nodes! -- to give clients suggestions of placs to go to get their first consensus.
* | | Refactor add_trusted_dir_serverNick Mathewson2012-12-06
| | | | | | | | | | | | | | | | | | Now creating a dir_server_t and adding it are separate functions, and there are frontend functions for adding a trusted dirserver and a fallback dirserver.
* | | Rename trusted_dir_server_t to dir_server_t. Automatic renaming.Nick Mathewson2012-12-06
| | |
* | | Start refactoring trusted_dir_servers into trusted and fallback listsNick Mathewson2012-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | We use trusted_dir_server_t for two pieces of functionality: a list of all directory authorities, and a list of initial places to look for a directory. With this patch we start to separate those two roles. There is as of now no actual way to be a fallback directory without being an authority.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I removed version_supports_begindir, I accidentally removed the mechanism we had been using to make a directory cache self-test its directory port. This caused bug 6815, which caused 6814 (both in 0.2.4.2-alpha). To fix this bug, I'm replacing the "anonymized_connection" argument to directory_initiate_command_* with an enumeration to say how indirectly to connect to a directory server. (I don't want to reinstate the "version_supports_begindir" argument as "begindir_ok" or anything -- these functions already take too many arguments.) For safety, I made sure that passing 0 and 1 for 'indirection' gives the same result as you would have gotten before -- just in case I missed any 0s or 1s.

| * | Refactor smartlist_choose_node_by_bandwidth to be less horrible.Nick Mathewson2012-08-09
| | | | | | | | | | | | | | | | | | | | | | | | With this patch, I dump the old kludge of using magic negative numbers to indicate unknown bandwidths. I also compute each node's weighted bandwidth exactly once, rather than computing it once in a loop to compute the total weighted bandwidth and a second time in a loop to find which one we picked.
| * | Use a smarter fix for bug 1203.Nick Mathewson2012-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we had incremented rand_bw so that when we later tested "tmp >= rand_bw", we wouldn't have an off-by-one error. But instead, it makes more sense to leave rand_bw alone and test "tmp > rand_bw". Note that this is still safe. To take the example from the bug1203 writeup: Suppose that we have 3 nodes with bandwidth 1. So the bandwidth array is { 1, 1, 1 }, and the total bandwidth is 3. We choose rand_bw == 0, 1, or 2. With the first iteration of the loop, tmp is now 1; with the second, tmp is 2; with the third, tmp is 3. Now that our check is tmp > rand_bw, we will set i in the first iteration of the loop iff rand_bw == 0; in the second iteration of the loop iff rand_bw == 1, and in the third iff rand_bw == 2. That's what we want. Incidentally, this change makes the bug 6538 fix more ironclad: once rand_bw is set to UINT64_MAX, tmp > rand_bw is obviously false regardless of the value of tmp.
| * | Remove remaining timing-dependency in choosing nodes by bandwidthNick Mathewson2012-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old approach, because of its "tmp >= rand_bw && !i_has_been_chosen" check, would run through the second part of the loop slightly slower than the first part. Now, we remove i_has_been_chosen, and instead set rand_bw = UINT64_MAX, so that every instance of the loop will do exactly the same amount of work regardless of the initial value of rand_bw. Fix for bug 6538.
| * | Change smartlist_choose_node_by_bandwidth to avoid doubleNick Mathewson2012-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should make our preferred solution to #6538 easier to implement, avoid a bunch of potential nastiness with excessive int-vs-double math, and generally make the code there a little less scary. "But wait!" you say. "Is it really safe to do this? Won't the results come out differently?" Yes, but not much. We now round every weighted bandwidth to the nearest byte before computing on it. This will make every node that had a fractional part of its weighted bandwidth before either slighty more likely or slightly less likely. Further, the rand_bw value was only ever set with integer precision, so it can't accurately sample routers with tiny fractional bandwidth values anyway. Finally, doing repeated double-vs-uint64 comparisons is just plain sad; it will involve an implicit cast to double, which is never a fun thing.
