4c8fcba86c Fix more warnings from openbsd_malloc
Apparently, (void)writev is not enough to suppress the "you are
ignoring the return value!" warnings on Linux.  Instead, remove the
whole warning/error logic when compiling openbsd_malloc for Tor: we
can't use it.

ec6a7effb8 Bug 6475: Explicitly track our path bias state.
This is done to avoid spurious warns. Additional log lines are also
added to try to track down the codepaths where we are somehow overcounting
success counts.

6a33c33a12 Fix warnings and 64-bit problems in openbsd-malloc code
The warning fixes are:
  - Only define issetugid if it's missing.
  - Explicitly ignore the return value of writev.
  - Explicitly cast the retval of readlink() to int.

The 64-bit problems are related to just storing a size_t in an int. Not cool!  Use a size_t instead.

Fix for bug 6379. Bugfix on 0.2.0.20-rc, which introduced openbsd-malloc.

2ba52f4095 Fix wildcarded address mappings from the control port
Apparently, we weren't actually detecting wildcardedness when parsing

959f850056 Raise the part of torrc mapaddress handling that knows wildcards
This patch extracts the inner part of config_register_addressmaps --
the part that knows about detecting wildcard addresses addresses --
and makes it into a new function.  The new function is deliberately
not moved or reindented, so that the diff is smaller.

I need this to fix bug 6244.

dfe03d36c8 Don't infer we have a FooPort from the presence of a FooPort line
Thanks to the changes we started making with SocksPort and friends
in 0.2.3.3-alpha, any of our code that did "if (options->Sockport)"
became wrong, since "SocksPort 0" would make that test true whereas
using the default SocksPort value would make it false.  (We didn't
actually do "if (options->SockPort)" but we did have tests for
TransPort.  When we moved DirPort, ORPort, and ControlPort over to
the same system in 0.2.3.9-alpha, the problem got worse, since our
code is littered with checks for DirPort and ORPort as booleans.

This code renames the current linelist-based FooPort options to
FooPort_lines, and adds new FooPort_set options which get set at
parse-and-validate time on the or_options_t.  FooPort_set is true
iff we will actually try to open a listener of the given type. (I
renamed the FooPort options rather than leave them alone so that
every previous user of a FooPort would need to get inspected, and so
that any new code that forgetfully uses FooPort will need fail to
compile.)

Fix for bug 6507.

d48cebc5e4 Try to clarify impact of bug 6537
I don't personally agree that this is likely to be easy to exploit,
and some initial experimention I've done suggests that cache-miss
times are just plain too fast to get useful info out of when they're
mixed up with the rest of Tor's timing noise.  Nevertheless, I'm
leaving Robert's initial changelog entry in the git history so that he
can be the voice of reason if I'm wrong. :)

308f6dad20 Mitigate a side-channel leak of which relays Tor chooses for a circuit
Tor's and OpenSSL's current design guarantee that there are other leaks,
but this one is likely to be more easily exploitable, and is easy to fix.

063138e001 Warn at parse time for routerstatus entry missing a microdesc consensus
In 0.2.3.18-rc, we started warning on this case while building a
list of missing microdescriptor digests.  That turned out to spam
the logs; instead let's warn at parse time.

Partial fix for bug 6404.

7143d112a6 Don't include a router in an md consensus if we can't find a md for it.
The spec requires that every router in a microdesc consensus have an
m line; we weren't obeying that spec.

This creates a new consensus method (13) to allow voting to continue
to work right. Partial fix for bug 6404; fix on 0.2.2.6-alpha.

c1bd104111 Detect bug 6252 (unexpected sendme cell)
I only check on circuits, not streams, since bloating your stream
window past the initial circuit window can't help you much.

Also, I compare to CIRCWINDOW_START_MAX so we don't have surprising
races if we lower CIRCWINDOW_START for an experiment.
