Instead, use compare_tor_addr_to_node_policy everywhere.
One advantage of this is that compare_tor_addr_to_node_policy can
better distinguish 0.0.0.0 from "unknown", which caused a nasty bug
with microdesc users.
Rationale: right now there seems to be no way for our bootstrap
status to dip under 100% once it has reached 100%. Thus, recording
broken connections after that point is useless, and wastes memory.
If at some point in the future we allow our bootstrap level to go
backwards, then we should change this rule so that we disable
recording broken connection states _as long as_ the bootstrap status
is 100%.
It's very easy for nodelist_add_node_family(sl,node) to accidentally
add 'node', and kind of hard to make sure that it omits it. Instead
of taking pains to leave 'node' out, let's instead make sure that we
always include it.
I also rename the function to nodelist_add_node_and_family, and
audit its users so that they don't add the node itself any longer,
since the function will take care of that for them.
Resolves bug 2616, which was not actually a bug.
Previously, we'd just take all the nodes in EntryNodes, see which
ones were already in the guard list, and add the ones that weren't.
There were some problems there, though:
* We'd add _every_ entry in EntryNodes, and add them in the order
they appeared in the routerlist. This wasn't a problem
until we added the ability to give country-code or IP-range
entries in the EntryNodes set, but now that we did, it is.
(Fix: We now shuffle the entry nodes before adding them; only
add up to 10*NumEntryGuards)
* We didn't screen EntryNodes for the Guard flag. That's okay
if the user has specified two or three entry nodes manually,
but if they have listed a whole subcontinent, we should
restrict ourselves to the entries that are currently guards.
(Fix: separate out the new guard from the new non-guard nodes,
and add the Guards first.)
* We'd prepend new EntryNodes _before_ the already configured
EntryNodes. This could lead to churn.
(Fix: don't prepend these.)
This patch also pre-screens EntryNodes entries for
reachableaddresses/excludenodes, even though we check for that
later. This is important now, since we cap the number of entries
we'll add.
All of the routerset_contains*() functions return 0 if their
routerset_t argument is NULL. Therefore, there's no point in
doing "if (ExcludeNodes && routerset_contains*(ExcludeNodes...))",
for example.
This patch fixes every instance of
if (X && routerstatus_contains*(X,...))
Note that there are other patterns that _aren't_ redundant. For
example, we *don't* want to change:
if (EntryNodes && !routerstatus_contains(EntryNodes,...))
Fixes#2797. No bug here; just needless code.
Returning a tristate is needless here; we can just use the yielded
transport/proxy_type field to tell whether there's a proxy, and have
the return indicate success/failure.
Also, store the proxy_type in the or_connection_t rather than letting
it get out of sync if a configuration reload happens between launching
the or_connection and deciding what to say with it.
- const-ify some transport_t pointers
- Remove a vestigial argument to parse_bridge_line
- Make it compile without warnings on my laptop with
--enable-gcc-warnings
Multiple Bridge lines can point to the same one ClientTransportPlugin
line, and we can have multiple ClientTransportPlugin lines in our
configuration file that don't match with a bridge. We also issue a
warning when we have a Bridge line with a pluggable transport but we
can't match it to a ClientTransportPlugin line.
* Renamed transport_info_t to transport_t.
* Introduced transport_get_by_name().
* Killed match_bridges_with_transports().
We currently *don't* detect whether any bridges miss their transports,
of if any transports miss their bridges.
* Various code and aesthetic tweaks and English language changes.
This lets us make a lot of other stuff const, allows the compiler to
generate (slightly) better code, and will make me get slightly fewer
patches from folks who stick mutable stuff into or_options_t.
const: because not every input is an output!
* Improved function documentation.
* Renamed find_bridge_transport_by_addrport() to
find_transport_by_bridge_addrport().
* Sanitized log severities we use.
* Ran check-spaces.
This merge was a bit nontrivial, since I had to write a new
node_is_a_configured_bridge to parallel router_is_a_configured_bridge.

Most instances were dead code; for those, I removed the assignments.
Some were pieces of info we don't currently plan to use, but which
we might in the future. For those, I added an explicit cast-to-void
to indicate that we know that the thing's unused. Finally, one was
a case where we were testing the wrong variable in a unit test.
That one I fixed.
This resolves bug 3208.
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.
This code changes it so that we don't remove bridges immediately when
we start re-parsing our configuration. Instead, we mark them all, and
remove all the marked ones after re-parsing our bridge lines. As we
add a bridge, we see if it's already in the list. If so, we just
unmark it.
This new behavior will lose the property we used to have that bridges
were in bridge_list in the same order in which they appeared in the
torrc. I took a quick look through the code, and I'm pretty sure we
didn't actually depend on that anywhere.
This is for bug 3019; it's a fix on 0.2.0.3-alpha.

Here I looked at the results of the automated conversion and cleaned
them up as follows:
If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
changed it to a fast_memcmp or fast_memeq.
Otherwise if there was a tor_memcmp that could turn into a
tor_memneq or tor_memeq, I converted it.
This wants close attention.
[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.
