Fix the bug that was making moria1 set valid-after wrong in its votes: we were looking at the preferred timing when we should have been looking at the consensus timing.
svn:r11818
Add a bunch of function documentation; clean up a little code; fix some XXXXs; tag the nonsensical EXTRAINFO_PURPOSE_GENERAL as nonsesnse; note another bit of "do not cache special routers" code to nuke.
svn:r11761
Use descriptor annotations to record the source, download t time, and purpose of every descriptor we add to the store. The remaining to-do item is to stop setting do_not_cache on bridges.
svn:r11680
More annotated-store work: handle annotations in lists correctly. Add ability to prepend annotations to a routerdesc (and to every rtouredesc in a list), while verifying that the routerdesc is not already annotated.
svn:r11665
Backend for descriptor annotations: parse annotations as keywords; only allow them to appear in the cache; do not serve them as part of the descriptor if we are a dirserver. Still need mechanism to set annotations. Still need to rename cache file.
svn:r11654
Fix a bug that made servers send a "404 Not found" in response to
attempts to fetch their server descriptor. This caused Tor servers
to take many minutes to establish reachability for their DirPort,
and it totally crippled bridges. Bugfix on 0.2.0.5-alpha.
svn:r11545
Finish implementing and documenting proposal 108: Authorities now use MTBF data to set their stability flags, once they have at least 4 days of data to use.
svn:r11240
More directory voting code. Now, if everything works, and I haven't forgotten anything, it is possible to set up some v3 authorities and start voting. Of course, I have probably forgotten something, and there are probably bugs in there somewhere too.
svn:r10976
Implement proposal 109: As an authority, never call more than 3 servers per IP Running and Valid. Prefer Running servers to non-running ones; then prefer high-bandwidth to low-bandwidth. Needs testing.
svn:r10968
at least 100KB/s, and consider their bandwidth adequate to be a
Guard if it is at least 250KB/s. This fix complements proposal
107. [Bugfix on 0.1.2.x]
svn:r10897
Refactor v3 vote generation code into "build a networkstatus_vote_t" and "format a networkstatus_vote_t". This should make testing possible.
svn:r10533
Adapt code to parse v3 networkstatus votes so it can also parse a consensus. Make networkstatus_vote_t the catch-all type for votes and conensuses. Correct/clarify the second argument to directory-signature.
svn:r10491
First draft of code to generate votes. needs testing. does not yet upload or serve votes. Shares most of its code with the old generate_v2_networkstatus.
svn:r10295
Partial backport candidate: do not rely on finding a \0 after an mmaped() router/extrainfo file. Also, set journal length correctly when starting up.
svn:r10248
authorities should set. This will let future authorities choose
not to serve V2 directory information.
Also, go through and revamp all the authdir_mode stuff so it tries
to do the right thing if you're an auth but not a V1 or V2 auth.
svn:r10092
(Needs review.) Allow directory authorities to accept multiple router descriptors and extra info documents in a single POST. This will make implementing the client side of proposal 104 a lot simpler.
svn:r10069
Backport candidate: Add asserts to dirserv_remove_invalid, and fix a bug in dirserv_remove_invalid that could mess with pointers in a freed routerinfo right after it was freed.
svn:r10052
More proposal-104 stuff: add most of the code for authorities to accept and serve extra-info documents. The back-end to store the things is missing.
svn:r9971
Add code to shrink the cell memory pool by discarding empty chunks that have been empty for the last 60 seconds. Also, instead of having test.c duplicate declarations for exposed functions, put them inside #ifdef foo_PRIVATE blocks in the headers. This prevents bugs where test.c gets out of sync.
svn:r9944
A surprisingly simple patch to stop reading on edge connections when their circuits get too full, and start again when they empty out. This lets us remove the logic to block begin_dir conns when the corresponding or conns get full: it was already broken by cell queues anyway.
svn:r9905
directory information requested inside Tor connections (i.e. via
begin_dir cells). It only triggered when the same connection was
serving other data at the same time. Reported by seeess.
Backport candidate.
svn:r9841
uptime of at least 30 days, even if that's not the median uptime
in the network. Implements proposal 1xx, suggested by Kevin Bauer
and Damon McCoy.
svn:r9788
Fix a bug in 9572: after we decref a defunct v1 directory, drop the main reference to it. Should fix bug 396. Many thanks to seeess for tracking this one down.
svn:r9648
nickname array, and only treating a server as reachable if
the array magically has the right nickname in it. this was
causing the authorities to label only themselves as running,
and clients were "mysteriously" failing.
svn:r9628
Removing the last DOCDOC comment hurt so much that I had to use Doxygen to identify undocumented macros and comments, and add 150 more DOCDOCs to point out where they were. Oops. Hey, kids! Fixing some of these could be your first Tor patch!
svn:r9477
This one is a little tricky. Our BEGIN_DIR implementation has a
problem: the dirserv conns will decide they can flush all their data
immediately, since the edge_conns will read greedily.
For our 0.1.2 workaround, we track which or_conn a bridged dirserv
conn is attached to, and stop writing when its outbuf is too full, and
start writing again when the or_conn's outbuf empties out a little.
This requires a bit of pointer management. Let's hope it works.
svn:r9432
Clear untrusted networkstatuses after 10 days too. (This is not a terribly awful bug, since we would only ever retain 16 of them, but it still might be nice to backport.) Resolves part A of bug 372.
svn:r9324
Fix computation of total_exit_bandwidth; this will cause exits not to get recommended as guards if the total exit bandwidth if they constitute less than a third of total available bandwidth. There may be problems here with flapping; lets see if they occur in practice.
svn:r9281
Add (and specify) a BadDirectory flag to networkstatuses, so authorities can tell clients that some caches are broken. Also, implement an as-yet-unused function to estimate how many bytes will be sent on a directory connection.
svn:r9255
11:23 < armadev> typo
11:23 < nickm> ?
11:23 < armadev> did you get the coffee yet? :)
11:23 < nickm> no

Try to compile with fewer warnings on irix64's MIPSpro compiler /
environment, which apparently believes that:
- off_t can be bigger than size_t.
- only mean kids assign things they do not subsequently inspect.
I don't try to fix the "error" that makes it say:
cc-3970 cc: WARNING File = main.c, Line = 1277
conversion from pointer to same-sized integral type (potential portability
problem)
uintptr_t sig = (uintptr_t)arg;
Because really, what can you do about a compiler that claims to be c99
but doesn't understand that void* x = NULL; uintptr_t y = (uintptr_t) x;
is safe?
svn:r8948
Let directory authorities set the BadExit flag if they like. Also, refactor directory authority code so we can believe multiple things about a single router, and do fewer linear searches.
svn:r8794
Add unit tests for tor_mmap_file(); make tor_mmap_t.size always be the size of the file (not the size of the mapping); add an extra argument to read_file_to_str() so it can return the size of the result string.
svn:r8762
The otherwise regrettable MIPSpro C compiler warns about values set but never used, and about mixing enums and ints; these are good warnings, and so should be fixed. This removes some dead code and some potential bugs. Thanks to pnx.
svn:r8664
Reserve the nickname "Unnamed" for routers that can't pick a hostname; any
router can call itself Unnamed; directory servers will never allocate Unnamed
to any particular router; clients won't believe that any router is the
canonical Unnamed.
svn:r8529
Make "is a v1 authority", "is a v2 authority", and "is a hidden service authority" into separate flags so we can eventually migrate more trust away from moria.
