24b7b922ae Actually free the worker_state_t object when we do an update with it
Previously we freed the old "keys" object, but leaked the
worker_state_t that we had taken it from.

Fixes bug 20401; bugfix on 0.2.6.3-alpha.

d73c671d6d policy_is_reject_star():
ome policies are default-reject, some default-accept.  But
policy_is_reject_star() assumed they were all default_reject.  Fix
that!

Also, document that policy_is_reject_star() treats a NULL policy as
empty. This allows us to simplify the checks in
parse_reachable_addresses() by quite a bit.

Fxes bug 20306; bugfix on 0.2.8.2-alpha.

8841a9e396 Create single-onion-service directory before poisoning it, if needed
(Also, refactor the code to create a hidden service directory into a
separate funcion, so we don't have to duplicate it.)

Fixes bug 20484; bugfix on 0.2.9.3-alpha.

Rename routerstatus_version_supports_ntor to *_supports_extend2_cells

Refactor circuit_pick_create_handshake

circuit_pick_extend_handshake.

No behaviour change.

In circuit_pick_extend_handshake, assume all hops support EXTEND2 and ntor
This simplifies the function: if we have an ntor key, use ntor/EXTEND2,
otherwise, use TAP/EXTEND.

d288704023 Avoid tor_fragile_assert() failure with DNSPort on RESOLVED_TYPE_ERROR
The tor_fragile_assert() bug has existed here since c8a5e2d588
in tor-0.2.1.7-alpha forever, but tor_fragile_assert() was mostly a
no-op until 0.2.9.1-alpha.

Fixes bug 19869.

3cea86eb2f Add a one-word sentinel value of 0x0 at the end of each buf_t chunk
This helps protect against bugs where any part of a buf_t's memory
is passed to a function that expects a NUL-terminated input.

It also closes TROVE-2016-10-001 (aka bug 20384).

aae034d13e Write a bunch of module documentation.
This commit adds or improves the module-level documenation for:

  buffers.c circuitstats.c command.c connection_edge.c control.c
  cpuworker.c crypto_curve25519.c crypto_curve25519.h
  crypto_ed25519.c crypto_format.c dircollate.c dirserv.c dns.c
  dns_structs.h fp_pair.c geoip.c hibernate.c keypin.c ntmain.c
  onion.c onion_fast.c onion_ntor.c onion_tap.c periodic.c
  protover.c protover.h reasons.c rephist.c replaycache.c
  routerlist.c routerparse.c routerset.c statefile.c status.c
  tor_main.c workqueue.c

In particular, I've tried to explain (for each documented module)
what each module does, what's in it, what the big idea is, why it
belongs in Tor, and who calls it.  In a few cases, I've added TODO
notes about refactoring opportunities.

I've also renamed an argument, and fixed a few DOCDOC comments.

df84536ac1 Add a logic-consistency test when parsing unix socket configs
Coverity couldn't tell that 'addrport' was always non-NULL at this
point in the function, so I'm adding an explicit check. This closes

87865c8aca Extract ExitPolicy-and-IPv6Exit check into a new function
(I've done this instead of changing the semantics of
router_compare_to_my_exit_policy, because dns.c uses
router_compare_to_my_exit_policy too, in a slightly weird way.)

7026b607a0 Fix spurious compiler warning in do_getpass().
Some compilers apparently noticed that p2len was allowed to be equal
to msg, and so maybe we would be doing memset(prompt2, ' ', 0), and
decided that we probably meant to do memset(prompt2, 0, 0x20);
instead.

Stupid compilers, doing optimization before this kind of warning!

My fix is to just fill the entire prompt2 buffer with spaces,
because it's harmless.

Bugfix on e59f0d4cb9, not in any released Tor.

785176e975 Clean up and fix exit policy check in connection_exit_connect().
Previously, we would reject even rendezvous connections to IPv6
addresses when IPv6Exit was false.  But that doesn't make sense; we
don't count that as "exit"ing.  I've corrected the logic and tried
to make it a lottle more clear.

Fixes bug 18357; this code has been wrong since 9016d9e829 in
0.2.4.7-alpha.

847e001d28 Bug 20261: Disable IsolateClientAddr on AF_LOCAL SocksPorts.
The client addr is essentially meaningless in this context (yes, it is
possible to explicitly `bind()` AF_LOCAL client side sockets to a path,
but no one does it, and there are better ways to grant that sort of
feature if people want it like using `SO_PASSCRED`).
