If the consensus does not contain Exits, Tor will only build internal
circuits. In this case, relevant statuses will contain the word "internal"
as indicated in the Tor control-spec.txt. When bootstrap completes,
Tor will be ready to handle an application requesting an internal
circuit to hidden services at ".onion" addresses.
If a future consensus contains Exits, exit circuits may become available.
Tor already notifies the user at "notice" level if they have no exits in
the consensus, and can therefor only build internal paths.
Consequential change from #13718.
Bugfix on ed8f020e205267e6270494634346ab68d830e1d8; bug not in any
released version of Tor. Found by Coverity; this is CID 1239290.
[Yes, I used this commit message before, in 58e813d0fc.
Turns out, that fix wasn't right, since I didn't look up a
screen. :P ]
Uses libscrypt when found; otherwise, we don't have scrypt and we
only support openpgp rfc2440 s2k hashing, or pbkdf2.
Includes documentation and unit tests; coverage around 95%. Remaining
uncovered code is sanity-checks that shouldn't be reachable fwict.
Return an error when the second or later arguments of the
"setevents" controller command are invalid events. Previously we
would return success while silently skipping invalid events.
Fixes bug 13205; bugfix on 0.2.3.2-alpha. Reported by "fpxnns".
Back in 078d6bcd, we added an event number 0x20, but we didn't make
the event_mask field big enough to compensate.
Patch by "teor". Fixes 13085; bugfix on 0.2.5.1-alpha.
Most of these are in somewhat non-obvious code where it is probably
a good idea to initialize variables and add extra assertions anyway.
Closes 13036. Patches from "teor".
Coverity doesn't like doing NULL checks on things that can't be
NULL; I like checking things where the logic for their not being
NULL is nontrivial. Let's compromise, and make it obvious that this
field can't be NULL.

When we merged the cookieauthfile creation logic in 33c3e60a37, we
accidentally took out this feature. Fixes bug 12864, bugfix on
0.2.5.1-alpha.
Also adds an ExtORPortCookieAuthFileGroupReadable, since there's no
reason not to.
When running with User set, we frequently try to look up our
information in the user database (e.g., /etc/passwd). The seccomp2
sandbox setup doesn't let us open /etc/passwd, and probably
shouldn't.
To fix this, we have a pair of wrappers for getpwnam and getpwuid.
When a real call to getpwnam or getpwuid fails, they fall back to a
cached value, if the uid/gid matches.
(Granting access to /etc/passwd isn't possible with the way we
handle opening files through the sandbox. It's not desirable either.)
This is a fix for 9963. I say this is a feature, but if it's a
bugfix, it's a bugfix on 0.2.4.18-rc.

This should fixes some "hey, that function could have
__attribute__((noreturn))" warnings introduced by f96400d9.
Bug not in any released version of Tor.
According to control spec, longname should not contain any spaces and is
consists only of identy_digest + nickname
added two functions:
* node_get_verbose_nickname_by_id()
* node_describe_longname_by_id()
If you want a slow shutdown, send SIGNAL SHUTDOWN.
(Why not just have the default be SIGNAL QUIT? Because this case
should only happen when an owning controller has crashed, and a
crashed controller won't be able to give the user any "tor is
shutting down" feedback, and so the user gets confused for a while.
See bug 10449 for more info)
The remaining vestige is that we continue to publish the V2dir flag,
and that, for the controller, we continue to emit v2 directory
formats when requested.
Don't cast uint64_t * to const uint64_t * explicitly. The cast is always
safe, so C does it for us. Doing the cast explitictly can hide bugs if
the input is secretly the wrong type.
Suggested by Nick.
There were only two functions outside of circuitstats that actually
wanted to know what was inside this. Making the structure itself
hidden should help isolation and prevent us from spaghettifying the
thing more.
Use the generic function for both the ControlPort cookie and the
ExtORPort cookie.
Also, place the global cookie variables in the heap so that we can
pass them around more easily as pointers.
Also also, fix the unit tests that broke by this change.

We previously used FILENAME_PRIVATE identifiers mostly for
identifiers exposed only to the unit tests... but also for
identifiers exposed to the benchmarker, and sometimes for
identifiers exposed to a similar module, and occasionally for no
really good reason at all.
Now, we use FILENAME_PRIVATE identifiers for identifiers shared by
Tor and the unit tests. They should be defined static when we
aren't building the unit test, and globally visible otherwise. (The
STATIC macro will keep us honest here.)
For identifiers used only by the unit tests and never by Tor at all,
on the other hand, we wrap them in #ifdef TOR_UNIT_TESTS.
This is not the motivating use case for the split test/non-test
build system; it's just a test example to see how it works, and to
take a chance to clean up the code a little.
- Rename n_read and n_written in origin_circuit_t to make it clear that
these are only used for CIRC_BW events.
- Extract new code in control_update_global_event_mask to new
clear_circ_bw_fields function.
- Avoid control_event_refill_global function with 13 arguments and
increase code reuse factor by moving more code from control.c to
connection.c.
- Avoid an unsafe uint32_t -> int cast.
- Add TestingEnableTbEmptyEvent option.
- Prepare functions for testing.
- Rename a few functions and improve documentation.
- Move cell_command_to_string from control.c to command.c.
- Use accessor for global_circuitlist instead of extern.
- Add a struct for cell statistics by command instead of six arrays.
- Split up control_event_circuit_cell_stats by using two helper functions.
- Add TestingEnableCellStatsEvent option.
- Prepare functions for testing.
- Rename a few variables and document a few things better.
- Move new ID= parameter in ORCONN event to end. Avoids possible trouble
from controllers that parse parameters by position, even though they
shouldn't.
When we're hibernating, the main reqason we can't bootstrap will
always be that we're hibernating: reporting anything else at severity
WARN is pointless.
