62477906e9 Fix remaining case of circpathbias inspecting entryguard internals 2016-11-30 14:42:52 -05:00
Nick Mathewson
823357dbe4 Add an entry_guard_describe() function 
This function helpfully removes all but one remaining use of
an entry_guard_t private field in pathbias.c

be447bc770 Move path-bias fields into a separate structure 
(Other than the field movement, the code changes here are just
search-and-replace)

22f2f13f81 prop271: make entry_guard_t mostly-private 
The entry_guard_t structure should really be opaque, so that we
can change its contents and have the rest of Tor not care.

This commit makes it "mostly opaque" -- circpathbias.c can still see
inside it.  (I'm making circpathbias.c exempt since it's the only
part of Tor outside of entrynodes.c that made serious use of
entry_guard_t internals.)

bfaded9143 Bridge-using clients now use their cached microdesc consensus 
Clients that use bridges were ignoring their cached microdesc-flavor
consensus files, because they only thought they should use the microdesc
flavor once they had a known-working bridge that could offer microdescs,
and at first boot no bridges are known-working.

This bug caused bridge-using clients to download a new microdesc consensus
on each startup.

Fixes bug 20269; bugfix on 0.2.3.12-alpha.

f2153f9716 Always allow OR connections to bridges on private addresses 
Regardless of the setting of ExtendAllowPrivateAddresses.

This fixes a bug with pluggable transports that ignore the
(potentially private) address in their bridge line.

Fixes bug 18517; bugfix on 23b088907f in tor-0.2.8.1-alpha.

- Make bridge_add_from_config() accept a struct.
- Make string_is_key_value() less hysterical.

b03553737c Separate the flags for logging use bias. 
I think we want both sets of messages to appear independently to help us know
what needs tuning.

bce5019eff generalize choose_random_entry()'s dirinfo parameter 
Now we can specify to skip bridges that wouldn't be able to answer the
type of dir fetch we're launching.

It's still the responsibility of the rest of the code to prevent us from
launching a given dir fetch if we have no bridges that could handle it.

a8297cdbd3 use microdescriptors if *any* of our bridges can handle them 
Now as we move into a future where most bridges can handle microdescs
we will generally find ourselves using them, rather than holding back
just because one of our bridges doesn't use them.

e13e30221e Implement Path use bias accounting. 
Path use bias measures how often we can actually succeed using the circuits we
actually try to use. It is a subset of path bias accounting, but it is
computed as a separate statistic because the rate of client circuit use may
vary depending on use case.

a90f165b83 Rename first_hop to circ_attempt. 
Since we've generalized what we can count from (first or second hop), we
should generalize the variable and constant naming too.
