368825ff45 Sandbox: Don't preseed getaddrinfo(gethostname()) in client mode. 
If we're a server with no address configured, resolve_my_hostname
will need this.  But not otherwise.  And the preseeding itself can
consume a few seconds if like tails we have no resolvers.

dd7c999617 Make unix sockets work with the linux seccomp2 sandbox again 
I didn't want to grant blanket permissions for chmod() and chown(),
so here's what I had to do:
   * Grant open() on all parent directories of a unix socket
   * Write code to allow chmod() and chown() on a given file only.
   * Grant chmod() and chown() on the unix socket.

really don't like giving the sandbox permission to alter
permissions.

d8b93b31a0 hs: Do not close desc fetch conn. if we can't pick an HSDir 
Launching 7 descriptor fetches makes a connection to each HSDir that is 6
and the seventh one fails to pick an HSDir because they are all being used
already so it was killing all pending connections at once.

5390296338 rip out hid_serv_acting_as_directory() 
When we made HidServDirectoryV2 always 1, we removed the situation
where a relay could choose not to be an HSDir. Now simplify the
rest of the code to reflect this decision.

(We have to remove two apparently unrelated free() calls in the unit
tests, since they used to free stuff that we created as a side effect
of calling router_get_my_routerinfo(), and now we no longer call that.)

e167910fce rip out hid_serv_responsible_for_desc_id() 
This simplifies relay behavior, because the relay offers the hsdir
functionality independent of whether the directory authorities have
decided this relay is suitable for clients to use yet.

db263442af enable and test transproxy on FreeBSD derivatives #18448 
The transproxy feature is only enabled when __FreeBSD__ is defined, and
only regular FreeBSD does that.  Change this to __FreeBSD_kernel__ which
is defined on derivatives as well.

This enables the relevant options/validate__transproxy test on FreeBSD
derivatives.

5f7df92571 Remove support for unsigned time_t 
We've never actually tested this support, and we should probably assume
it's broken.

To the best of my knowledge, only OpenVMS has this, and even on
OpenVMS it's a compile-time option to disable it.  And I don't think
we build on openvms anyway.  (Everybody else seems to be working
around the 2038 problem by using a 64-bit time_t, which won't expire
for roughly 292 billion years.)

with 0 DirPorts when restarted. (Particularly during Tor version
upgrades.)

Ignore low fallback directory count in alpha builds.

be841f77aa Compatibility defines should be used for LibreSSL. 
LibreSSL doesn't use OpenSSL_version (it uses the older SSLeay_version
API), but it reports a major version number as 2 in
OPENSSL_VERSION_NUMBER. Instead of fudging the version check, for now,
let's just check if we're using LibreSSL by checking the version number
macro exists, and use compatibility defines unconditionally when we
detect LibreSSL.

* DIGEST_SHA3_[256,512] added as supported algorithms, which do

 * test/bench now benchmarks all of the supported digest algorithms,
   so it's possible to see just how slow SHA-3 is, though the message
   sizes could probably use tweaking since this is very dependent on
   the message size vs the SHA-3 rate.

The fix here is to prevent iteration over the list that other

2d2312d989 Conform to the type signature of setsockopt(2) 
According to the POSIX standard the option value is a pointer to void
and the option length a socklen_t. The Windows implementation makes the
option value be a pointer to character and the option length an int.

Casting the option value to a pointer to void conforms to the POSIX
standard while the implicit cast to a pointer to character conforms to
the Windows implementation.

The casts of the option length to the socklen_t data type conforms to
the POSIX standard. The socklen_t data type is actually an alias of an
int so it also conforms to the Windows implementation.

When a relay does not have an open directory port but it has an
orport configured and is accepting client connections then it can
now service tunnelled directory requests, too. This was already true
of relays with an dirport configured.

We also conditionally stop advertising this functionality if the
relay is nearing its bandwidth usage limit - same as how dirport
advertisement is determined.

4c1c2a313d Add Fallback Directory Candidate Selection Script 
"Tor has included a feature to fetch the initial consensus from nodes
 other than the authorities for a while now. We just haven't shipped a
 list of alternate locations for clients to go to yet.

 Reasons why we might want to ship tor with a list of additional places
 where clients can find the consensus is that it makes authority
 reachability and BW less important.

 We want them to have been around and using their current key, address,
 and port for a while now (120 days), and have been running, a guard,
 and a v2 directory mirror for most of that time."

Features:
* whitelist and blacklist for an opt-in/opt-out trial.
* excludes BadExits, tor versions that aren't recommended, and low
  consensus weight directory mirrors.
* reduces the weighting of Exits to avoid overloading them.
* places limits on the weight of any one fallback.
* includes an IPv6 address and orport for each FallbackDir, as
  implemented in #17327. (Tor won't bootstrap using IPv6 fallbacks
  until #17840 is merged.)
* generated output includes timestamps & Onionoo URL for traceability.
* unit test ensures that we successfully load all included default
  fallback directories.

Closes ticket #15775. Patch by "teor".

longer takes or returns len.)

07cca627ea Fix backtrace compilation on FreeBSD 
On FreeBSD backtrace(3) uses size_t instead of int (as glibc does). This
causes integer precision loss errors when we used int to store its
results.

The issue is fixed by using size_t to store the results of backtrace(3).

The manual page of glibc does not mention that backtrace(3) returns
negative values. Therefore, no unsigned integer wrapping occurs when its
result is stored in an unsigned data type.

The hidden service descriptor cache (rendcache) tests use digest maps

Because the tests use key strings with a length lower than DIGEST_LEN,
the internal copy operation reads outside the key strings which leads to
buffer over-reads.

we do not allow that in circuit_extend().

This commit now rejects a rendezvous point that has a local address once
seen at the hidden service side unless ExtendAllowPrivateAddresses is set.

e9bf584694 Format IPv6 policies correctly. 
Previously we'd suppressed the mask-bits field in the output when
formatting a policy if it was >=32.  But that should be a >=128 if
we're talking about IPv6.

Since we didn't put these in descriptors, this bug affects only log
messages and controller outputs.

Fix for bug 16056.  The code in question was new in 0.2.0, but the
bug was introduced in 0.2.4 when we started supporting IPv6 exits.

be0891667e Fix undefined behavior caused by memory overlap 
The tor_cert_get_checkable_sig function uses the signing key included in
the certificate (if available) when a separate public key is not given.

When the signature is valid, the tor_cert_checksig function copies the
public key from the checkable structure to the public key field of the
certificate signing key.

In situations where the separate public key is not given but the
certificate includes a signing key, the source and destination pointers
in the copy operation are equal and invoke undefined behavior.

Undefined behaviour is avoided by ensuring both pointers are different.

Move the code that rejects publicly routable exit relay addresses

addresses.

This removes the duplicate reject checks on local_address and
ipv6_local_address, but duplicates will be removed by
exit_policy_remove_redundancies at the end of the function.

This also removes the info-level logging on rejected interface
addresses. Instead, log a debug-level message in
addr_policy_append_reject_addr.

This simplifies policies_parse_exit_policy_internal and prepares for
reporting these addresses over the control port in #17183.

86eba14ac5 Fix unit tests on systems without IPv4 or localhost addresses 
Make unit tests pass on IPv6-only systems, and systems without
localhost addresses (like some FreeBSD jails).

Fixes:
* get_if_addrs_ifaddrs: systems without localhost
* get_if_addrs_ioctl: only works on IPv4 systems
* socket: check IPv4 and IPv6, skip on EPROTONOSUPPORT
* socketpair_ersatz: uses IPv4, skip on EPROTONOSUPPORT

Fixes bug #17632; bugfix on unit tests in 0.2.7.3-rc.
c464a36772 was a partial fix for this issue in #17255;
it was released in unit tests in 0.2.7.4-rc.

85bb71049a Fix a startup time assert caused by periodic events not being initialized. 
Loading a on disk bridge descriptor causes a directory download to be
scheduled, which asserts due to the periodic events not being
initialized yet.

84b3350c83 Be more conservative in scanning the list of pending streams 
Now we only re-scan the list in the cases we did before: when we
have a new circuit that we should try attaching to, or when we have
added a new stream that we haven't tried to attach yet.

This is part of 17590.

b1d56fc589 Decouple ..attach_circuit() from most of its callers. 
Long ago we used to call connection_ap_handshake_attach_circuit()
only in a few places, since connection_ap_attach_pending() attaches
all the pending connections, and does so regularly.  But this turned
out to have a performance problem: it would introduce a delay to
launching or connecting a stream.

We couldn't just call connection_ap_attach_pending() every time we
make a new connection, since it walks the whole connection list.  So
we started calling connection_ap_attach_pending all over, instead!
But that's kind of ugly and messes up our callgraph.

So instead, we now have connection_ap_attach_pending() use a list
only of the pending connections, so we can call it much more
frequently.  We have a separate function to scan the whole
connection array to see if we missed adding anything, and log a
warning if so.

Closes ticket #17590

1eb838b303 Work around openssl declaring x509_get_not{Before,After} as functions 
Now that x509_get_not{Before,After} are functions in OpenSSL 1.1
(not yet releasesd), we need to define a variant that takes a const
pointer to X509 and returns a const pointer to ASN1_time.

Part of 17237. I'm not convinced this is an openssl bug or a tor
bug. It might be just one of those things.

3ea834ce0a get_interface_address6_list(): Bring back a return code check 
... that was removed by 31eb486c46 which first appeared in
0.2.7.3-rc.

If tor is running in a ElectroBSD (or FreeBSD) jail it can't
get any IP addresses that aren't assigned to the jail by
looking at the interfaces and (by design) the
get_interface_address6_via_udp_socket_hack() fallback doesn't
work either.

The missing return code check resulted in tor_addr_is_internal()
complaining about a "non-IP address of type 49", due to reading
uninitialised memory.
