389b37246e Remove overly strict assertions in transports.c.
This patch removes an overly strict tor_assert() and an ignorable BUG()
expression. Both of these would trigger if a PT was unable to configure
itself during startup. The easy way to trigger this is to configure an
obfs4 bridge where you make the obfs4 process try to bind on a port
number under 1024.

7a64f6ea04 Ensure that the exit callback is called if CreateProcessA() fails on Windows.
This patch fixes an issue where the exit handler is not called for the
given process_t in case CreateProcessA() fails. This could, for example,
happen if the user tries to execute a binary that does not exist.

85b4a5c276 Handle errors from execve() in the Unix process backend more gracefully.
This patch removes a call to tor_assert_unreached() after execve()
failed. This assertion leads to the child process emitting a stack trace
on its standard output, which makes the error harder for the user to
demystify, since they think it is an internal error in Tor instead of
"just" being a "no such file or directory" error.

The process will now instead output "Error from child process: X" where
X is the stringified version of the errno value.

db18ff9120 Move code to add default log into quiet_level.c

3a73f6612a Replace add_temp_log() with add_default_log().
We used to have this function so that we could mark our initial
log-to-stdout as specifically temporary so that we would delete it
once regular logs were configured.  But it's no longer necessary to
mark these logs as temporary, since we now use a mark-and-sweep
process to ensure that _all_ not-configured logs are closed when we
change our configuration.

Instead, this function will be the basis of a refactoring in how we
handle default logs.

bfdfaae040 Move responsibility for setting the "quiet level" into a table.
Previously this was done with a big list of options in main.c which
implied "hush" or "quiet".  One of these options ("--digests") no
longer existed, but we still checked for it.

Now we use the table of command-line-only arguments to set this
value.

d91ad5112e Check tor_vasprintf for error return values.
In case of error, a negative value will be returned or NULL written into
first supplied argument.

This patch uses both cases to comply with style in the specific files.

A tor_vasprintf error in process_vprintf would lead to a NULL dereference
later on in buf_add, because the return value -1 casted to size_t would
pass an assertion check inside of buf_add.

On the other hand, common systems will fail on such an operation, so it
is not a huge difference to a simple assertion. Yet it is better to
properly fail instead of relying on such behaviour on all systems.

984a28f3e5 hs-v3: Make service pick the exact amount of intro points
When encoding introduction points, we were not checking if that intro points
had an established circuit.

When botting up, the service will pick, by default, 3 + 2 intro points and the
first 3 that establish, we use them and upload the descriptor.

However, the intro point is removed from the service descriptor list only when
the circuit has opened and we see that we have already enough intro points, it
is then removed.

But it is possible that the service establishes 3 intro points successfully
before the other(s) have even opened yet.

This lead to the service encoding extra intro points in the descriptor even
though the circuit is not opened or might never establish (#31561).

We have a getaddrinfo() implementation that we prefer, and a

2b825a1a2e Fix a crash bug in max_u16_in_sl()
The documentation for this function says that the smartlist can
contain NULLs, but the code only handled NULLs if they were at the
start of the list.

We didn't notice this for a long time, because when Tor is run
normally, the sequence of msg_id_t is densely packed, and so this
list (mapping msg_id_t to channel_id_t) contains no NULL elements.
We could only run into this bug:
  * when Tor was running in embedded mode, and starting more than once.
  * when Tor ran first with more pubsub messages enabled, and then
    later with fewer.
  * When the second run (the one with fewer enabled pubsub messages)
    had at least some messages enabled, and those messages were not
    the ones with numerically highest msg_id_t values.

39640728c3 Add comments to try to prevent recurrence of #31495.
There is a bad design choice in two of our configuration types,
where the empty string encodes a value that is not the same as the
default value.  This design choice, plus an implementation mistake,
meant that config_dup() did not preserve the value of routerset_t,
and thereby caused bug #31495.

This comment-only patch documents the two types with the problem,
and suggests that implementors try to avoid it in the future.

Closes ticket 31907.

log: explain why it is safe to leave the log mutex initialized
The log mutex is dynamically initialized, guarded by log_mutex_initialized.
We don't want to destroy it, because after it is destroyed, we won't see
any more logs.

If tor is re-initialized, log_mutex_initialized will still be 1. So we
won't trigger any undefined behaviour by trying to re-initialize the
log mutex.

3c97ab3c24 Treat an unexpected constant-sized VERSIONS cell as a PROTOCOL_WARN.
We previously used tor_fragile_assert() to declare that this case
could not happen: VERSIONS cells are always supposed to be
variable-sized, right?

This is incorrect, though.  On a v1 link protocol connection, all
cells are fixed-sized.  There aren't supposed to be any VERSIONS
cells with this version of the protocol, but apparently, somebody
was messing up.  (The v1 link protocol is obsolete, so probably the
implementer responsible didn't mean to be using it.)

Fixes bug 31107.  Bugfix on 0.2.4.4-alpha, when we introduced a
