This warning would previously be given every time we tried to open a
connection to a foo.exit address, which could potentially be used to
flood the logs. Now, we don't allow this warning to appear more
than once every 15 minutes.
Fixes bug 31466; bugfix on 0.2.2.1-alpha, when .exit was first
deprecated.
Our dimap code asserts if you try to add the same key twice; this
can't happen if everything is running smoothly, but it's possible if
you try to start a relay where secret_onion_key_ntor is the same as
secret_onion_key_ntor.old.
Fixes bug 30916; bugfix on 0.2.4.8-alpha when ntor keys were
introduced.
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 (The v1 link protocol is obsolete, so probably the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
tor_fragile_assert() for this case.
These errors can occur if we are built on a system with support for
madvise(MADV_NOFORK) but then we are run on a system whose kernel
does not support that flag.
If the error is something that we don't tolerate at all, we now log
it before crashing.
Fixes bug 31696. I am calling this a bugfix on 0.4.1.1-alpha, where
we actually started using the map_anon code.
This is similar to, but not the same as, the fix for #31570.
Our code assumes that when we're configured to get IPv6 addresses
out of a TRANS_PF transparent proxy connection, we actually will.
But we didn't check that, and so FreeBSD started warning us about a
potential NULL pointer dereference.
Fixes part of bug 31687; bugfix on 0.2.3.4-alpha when this code was
added.
We used to do this on Windows only, but it appears to affect
multiple platforms when building with certain versions of GCC, and a
common pattern for defining the floating-point classifier functions.
Fixes part of 31687. I'm calling this a bugfux on 31687, when we
started suppressing these warnings on Windows.
When tor is missing descriptors for some primary entry guards, make the
log message less alarming. It's normal for descriptors to expire, as long
as tor fetches new ones soon after.
Fixes bug 31657; bugfix on 0.3.3.1-alpha.
tor-github/pr/1283, with the following changes:
* cherry-pick the merge commit in 1283 on top of...
* tor-github/pr/1174, but with the last commit re-worded to remove
the fixup, because fixups break our push rules.
This is an "ours" merge, except for the bugfix version change in
changes/bug30649.

Some platforms (macOS, maybe others?) can swallow the last write before an
abort. This issue is probably caused by a race condition between write
buffer cache flushing, and process termination. So we write an extra
newline, to make sure that the message always gets through.
Fixes bug 31571; bugfix on 0.3.5.1-alpha.
This fixes LTO compilation for Android and -O0 compilation in
general, when --disable-module-dirauth is provided.

On some windows builds, time_t is 64 bits but long is not. This is
causing appveyor builds to fail.
Also, one of our uses of labs() on time_t was logically incorrect:
it was telling us to accept NETINFO cells up to three minutes
_before_ the message they were responding to, which doesn't make
sense.
This patch adds a time_abs() function that we should eventually move
to intmath.h or something. For now, though, it will make merges
easier to have it file-local in channeltls.c.
Fixes bug 31343; bugfix on 0.2.4.4-alpha.
Padding circuits were regular cells that got closed before their padding
machine could finish. This means that they can still receive regular cells from
their past life, but they have no way or reason to answer them anymore. Hence
let's ignore them before they even get to the proper subsystems.
There is other code that uses this value, and some of it is
apparently reachable from inside router_dir_info_changed(), which
routerlist_free() apparently calls. (ouch!) This is a minimal fix
to try to resolve the issue without causing other problems.
Fixes bug 31003. I'm calling this a bugfix on 0.1.2.2-alpha, where
the call to router_dir_info_changed() was added to routerlist_free().
When we added LD_MESG, we created a conflict with the LD_NO_MOCK
flag. We now need 64 bits for log domains in order to fix this
issue.
Fixes bug 31080; bugfix on 0.4.1.1-alpha.
Replace the 157 fallbacks originally introduced in Tor 0.3.5.6-rc
in December 2018 (of which ~122 were still functional), with a
list of 148 fallbacks (70 new, 78 existing, 79 removed) generated
in June 2019.
Closes ticket 28795.
Note that we created extra lists from DE and US, but they didn't add
any more fallbacks when we tried to merge them.
Always publish bridge pluggable transport information in the extra info
descriptor, even if ExtraInfoStatistics is 0. This information is
needed by BridgeDB.
Fixes bug 30956; bugfix on 0.4.1.1-alpha.
When we consider all circuits in "waiting for guard" state to be promoted to
an "open" state, we were considering all circuits, even the one marked for
close.
This ultiamtely triggers a "circuit_has_opened()" called on the circuit that
is marked for close which then leads to possible undesirable behaviors within
a subsystem.
For instance, the HS subsystem would be unable to find the authentication key
of the introduction point circuit leading to a BUG() warning and a duplicate
mark for close on the circuit.
This commit also adds a unit test to make sure we never select marked for
close circuits when upgrading its guard state from waiting for guard to open.

Skip test_rebind when the TOR_SKIP_TEST_REBIND environmental variable
is set.
Skip test_rebind on macOS in Travis builds, because it is unreliable
on macOS on Travis.
Fixes bug 30713; bugfix on 0.3.5.1-alpha.
Leave the other rend and hs_ident data around until circuit free, since code
may still try to inspect it after marking the circuit for close. The
circuitmap is the important thing to clean up, since repurposed
intropoints must be removed from this map to ensure validity.

If "Log debug ..." is not set, the decrement never happens. This lead to the
package/deliver window to be out of sync at the stream level and thus breaking
the connection after 50+ cells.

Previously, we were looking at our global settings to see what kind
of proxy we had. But doing this would sometimes give us the wrong
results when we had ClientTransportPlugin configured but we weren't
using it for a particular connection. In several places in the
code, we had added checks to see if we were _really_ using a PT or
whether we were using a socks proxy, but we had forgotten to do so
in at least once case. Instead, since every time we call this
function we are asking about a single connection, it is probably
best just to make this function connection-specific.
Fixes bug 29670; bugfix on 0.2.6.2-alpha.
