#2615 ttdnsd crash HTTPS Everywhere/HTTPS Everywhere: Chrome ttdnsd: 0.8 defect Feb 22, 2011

It appears that if Tor is listening on port 53 (for DNSPort) and ttdnsd attempts to start, we'll segfault:

#13421 GoodBadISP's Revamp Internal Services/Wiki project Oct 15, 2014

Following a discussion on the mailing list [1] the GoodBadISP page could do with some updating and proper arranging.

Some of the categories I have in mind to make available in the table format are as follows: Country, Company Name, ASN, Bridges Allowed, Relays Allowed, Exits Allowed, Last Updated, Correspondence.

Would "Bridges Allowed" be a redundant measure since they won't be in the public sphere?

Moritz @ Torservers already has done a fair deal of work, some is outdated or could use an update though but it's a good place to start our focus and give inspiration where needed. [2] [3] [4]

#13473 Sort Existing GoodBadISP page into tables Internal Services/Wiki task Oct 19, 2014

The existing GoodBadISP tables need sorting into the new format. All opinions, feedback and communications to that ISP must go in the correct section on ISPCorrespondence page to keep the primary page clean and to the point since it will grow substantially over time.

The new format should be available soon after this ticket is posted as it will be done for the US hosts (good experiences).

#8177 Vidalia Help Documentation Out of Date Archived/Vidalia defect Feb 6, 2013

In the most recent release of the Tor Browser Bundle, the help documentation bundled with Vidalia (accessed by selecting Help) is out of date. A search of GeoIP will confirm this, as the documentation still lists the GeoIP lookup server at geoip.vidalia-project.net, which has not been maintained since 2010.

#12236 Don't display the full URL in token table User Experience/Tor Support enhancement Jun 9, 2014

I'm interesting in the token full URL only when I create a new token so I give it to the user. The rest of the time, I don't really care to see the full thing, only the hash, maybe. That could reduce the table width.

So this change needs also a change to the token creation action to display a big fat URL that I can easily get into the clipboard.

#18213 The parameter WarnUnsafeSocks does not work as specified in the documentation, no warning is logged in the log file Core Tor/Tor Tor: 0.2.??? defect Feb 2, 2016

The parameter WarnUnsafeSocks does not work as specified in the documentation, no warning is logged in the log file when a connection is done to an ip address.

If WarnUnsafeSocks 1 (default) is set there is no warning in the log file. If you look at the code for log_unsafe_socks_warning, the only case where an error is logged is when safe_socks is true. safe_socks is true only when SafeSocks parameter is set, but not when WarnUnsafeSocks is set.

The code should be

if (safe_socks || options->WarnUnsafeSocks) {

instead of

if (safe_socks) {

#15434 Tor dies if you send it a HUP before it read its config, and doesn't take PTs with it Core Tor/Tor Tor: 0.3.0.x-final defect Mar 22, 2015

When sending tor a HUP before it has read its config, it will die, without killing its PTs. Starting tor again will then result in more PT crashes, as the ports will already be used by previous instances.

#15713 toggling DisableNetwork during bootstrap causes delay Core Tor/Tor Tor: 0.2.??? defect Apr 17, 2015

While testing a fix for #11879, Kathy and I noticed that if the bootstrap process is interrupted by setting DisableNetwork=1 via the control port, Tor waits about a minute after DisableNetwork is set back to 0 before continuing network activity. We observed this problem on a Mac OS 10.8.5 system. Possibly related tickets: #9229, #11069.

Once release candidates for Tor Browser 4.5 are available, this should be reproducible by following these steps:

  1. Start Tor Browser and click "Connect".
  2. Click "Open Settings" in the connection progress window to interrupt the bootstrap process.
  3. Click "Connect" again. Notice that there is a delay before the bootstrap makes more progress.

We are also able to reproduce it using Tor and a manual (telnet) control port connection. Follow these steps (control port authentication is up to you):

  1. Remove all cached Tor data and start Tor like this:

./tor --defaults-torrc torrc-defaults -f torrc DisableNetwork 1

  1. Make a control port connection and issue this command:

SETCONF DisableNetwork=0

  1. Wait for bootstrapping to reach 25-50% and then do:

SETCONF DisableNetwork=1

  1. Re-enable network access:

SETCONF DisableNetwork=0 Notice that there is a delay before the bootstrap makes more progress.

We used the torrc-defaults file that ships with Tor Browser 4.5a5:

# If non-zero, try to write to disk less frequently than we would otherwise.
AvoidDiskWrites 1
# Where to send logging messages.  Format is minSeverity[-maxSeverity]
# (stderr|stdout|syslog|file FILENAME).
Log notice stdout
# Bind to this address to listen to connections from SOCKS-speaking
# applications.

# receive connections from the Internet (the port for which you
# configured port forwarding).
ClientTransportPlugin flashproxy exec PluggableTransports/flashproxy-client --register :0 :9000

## meek configuration
ClientTransportPlugin meek exec PluggableTransports/meek-client-torbrowser -- PluggableTransports/meek-client

Our torrc is also from Tor Browser and it just contains a few paths:

DataDirectory /Users/.../tb-11879.app/TorBrowser/Data/Tor
GeoIPFile /Users/.../tb-11879.app/TorBrowser/Data/Tor/geoip
GeoIPv6File /Users/.../tb-11879.app/TorBrowser/Data/Tor/geoip6

I will attach some log output.

#15715 spurious "Network is unreachable" error after setting DisableNetwork=1 Core Tor/Tor Tor: 0.2.??? defect Apr 17, 2015

If DisableNetwork is set to 1 via SETCONF during bootstrapping, Tor sometimes generates spurious errors such as "Network is unreachable". Kathy and I saw this while testing a fix for #11879. We realize this may be difficult to fix due to the internal architecture / concurrency inside Tor.

See #15713 for steps to reproduce (but note that an error does not occur every time). In the log that is attached to #15713 you can see an example:

Apr 17 10:28:10.000 [warn] Problem bootstrapping. Stuck at 25%: Loading networkstatus consensus. (Network is unreachable; NOROUTE; count 1; recommendation warn; host 847B1F850344D7876491A54892F904934E4EB85D at

(the error happens right away if it happens at all – no delay).

This problem may cause some Tor Browser users to be a little confused; all they need to do is click "Open Settings" while Tor Browser was starting up and they will sometimes see an error alert.

#19162 Make it even harder to become HSDir Core Tor/Tor Tor: 0.3.0.x-final defect May 23, 2016

In #8243 we started requiring Stable flag for becoming HSDirs, but this is still not hard enough for motivated adversaries. Hence we need to make it even harder for a relay to become HSDir, so that only relays that have been around for long get the flag. After prop224 gets deployed, there will be less incentive for adversaries to become HSDirs since they won't be able to harvest onion addresses.

Until then, our current plan is to increase the bandwidth and uptime required to become an HSDir to something almost unreasonable. For example requiring an uptime of over 6 months, or maybe requiring that the relay is in the top 1/4th of uptimes on the network.

#17773 Should clients avoid using guards that lost the Guard flag? Core Tor/Tor Tor: 0.2.??? enhancement Dec 8, 2015

Nick and I both thought that at least in the past, Tor clients would stop using a relay as their guard, if it loses the Guard flag.

But it looks like the code doesn't do that -- once a relay is your guard, you'll use it in the guard position regardless of whether it has the Guard flag at this moment or not.

This is actually a tricky design decision. In favor of avoiding guards that don't have the guard flag:

  • If they get really slow, we can instruct clients to abandon them.
  • If a relay gets the guard flag for only a short period of time, it will have only a small number of (dedicated) users using it for the next months.

In favor of using non-Guard guards anyway:

  • An attacker can't push you away from your guard by hurting its performance in the eyes of the directory authorities.
  • You won't rotate guards as many times.

That "can't push you away" one looks big. What other aspects should we be considering here?

We need a consensus parameter that controls the deployment of proposal 224 that is next generation onion service.

Lots of code will go in tor without being used at first so this parameter will tell all the tor out there to start using the new generation onion service.

This is especially important before we merge HSDir support (#17238) in order for relay to NOT store 224 descriptors while the rest is under development.

I'm thinking OnionService224=0 (or we can omit 224 here and assume "OnionService" is next gen obviously :).

#14322 torsocks fails to wrap setcap binaries Core Tor/Torsocks defect Jan 22, 2015

the Linux 'capabilities' library for allowing non-root users to perform tasks which normally require elevated privileges.

at present the torsocks wrappers have checked for setuid and setgid flags on the binaries it executes and failed closed, throwing an error if this occurs, however there is currently no check to see if the binaries have capabilities applied.

in the case where they do, the LD_PRELOAD set by torsocks is stripped and the program will execute with no warning and without the torsocks wrapper.

as an example of this, the current 'ping' command on my Linux is setcap:

$ getcap which ping /usr/bin/ping = cap_net_raw+ep $ torsocks ping -c 1 torproject.org PING torproject.org ( 56(84) bytes of data. 64 bytes from icmp_seq=1 ttl=50 time=38.1 ms

To reproduce: clone a git repository using torsocks

Result: clone is successful, but produces an error in torsocks after an attempt to resolve the machine's hostname:42 using tor.

ERROR torsocks[pid]: Unable to resolve. Status reply: 4 (in socks5_recv_resolve_reply() at socks5.c:666)

#16934 youtube-dl (recent), torsocks 2.1.0 and TBB5+ failure Core Tor/Torsocks defect Aug 31, 2015

ERROR torsocks[29369]: [socks5] Resolve destination buffer too small (in socks5_recv_resolve_reply() at socks5.c:690) ERROR: Unable to download webpage: <urlopen error [Errno -4] Non-recoverable failure in name resolution> (caused by URLError(gaierror(-4, 'Non-recoverable failure in name resolution'),))

The error changes over time. But it is mostly in this range. With a fresh restart the problem goes away, but it is back after some time blocking all requests.

Stopping any TBB5 running and starting TBB4.5.3 makes everything go smooth again.

Besides TBB, nothing changes in the configuration.

#16991 I think I've figured out why torsocks-ci-linux is failing on Jenkins! Core Tor/Torsocks defect Sep 6, 2015

So, the tests seem to assume that there is a tor process running that can receive their queries, and that it's on the internet, and that while on the internet it can connect to the Tor network.

Not crazy I guess!

But FWICT the Jenkins builder hasn't launched a Tor process, or has shut off access to the network. I guess that's why it's failing in test_dns.c

So, the question:

Q1. Does torsocks really require for its tests that there exist a Tor process on port 9050 with access to the internet?

If the answer to Q1 is no, there is a bug in torsocks.

If the answer to Q1 is yes, there are three possible solutions I see:

S1. Change torsocks so that no tests require a running Tor with access to the internet. S2. Change the Jenkins configuration so that it launches a tor client process for the torsocks test to use. S3. Divide the torsocks tests into the ones that need a Tor connected to the network, and the ones that do not. Only run the ones that do not when we're running under Jenkins.

#11579 Torsocks should support Java Core Tor/Torsocks enhancement Apr 21, 2014

Right now Java programs run with torsocks have their network calls dropped, or sometimes crash. Torsocks should force Java programs to use Tor. This could be done by setting the proxy settings in the JVM with -DsockProxyHost= -DsocksProxyPort=8080. To ensure proxy obedience for DNS calls, torsocks might implement a DNS provider that uses SOCKS for resolution, add that to the classpath, and use it to override the DNS provider the JVM uses at runtime.

#11723 Support res_* API of libresolv Core Tor/Torsocks enhancement May 4, 2014

#11724 Check recvmmsg() FD passing on Unix socket for TCP socket Core Tor/Torsocks enhancement May 4, 2014

#11727 Support shared onion pool for DNS resolution in separate process Core Tor/Torsocks enhancement May 4, 2014

So it turns out that in irssi is doing DNS resolution in an other process and passing the result back to the first process which will make the connection.

This means that the two process have two distinct onion pools so the process doing the DNS resolution will store the onion address with the reserved cookie but the other process, when connecting using that cookie, will be unable to find the onion address in its pool.

One solution I have in mind is to create that onion pool in a shared memory (SHM) and hijack the clone/fork symbol so when we detect a new process we can set the onion pool reference in it thus sharing the pool across processes that have a common parent.

I have a PoC that works but maybe there could be an IPC approach instead.

We should implement a whitelist mechanism so the user can tell which local network is allowed such as localhost.

#13207 Is rend_cache_clean_v2_descs_as_dir cutoff crazy high? Core Tor/Tor Tor: 0.2.??? enhancement Sep 21, 2014
  time_t cutoff = now - REND_CACHE_MAX_AGE - REND_CACHE_MAX_SKEW;

That's currently 3 days.


config.c:  V(RendPostPeriod,              INTERVAL, "1 hour"),

So we expect our current one to get overwritten once an hour, yet if the hidden service goes away (stops publishing) we continue to serve its old (presumably no longer working) descriptor for 71 more hours.

One downside to this poor tuning is that we waste the time of clients who try to access the hidden service -- if we instead tell them there is no descriptor, they could go to another hsdir or give up more promptly.

One upside is that if we say we don't have one, clients *will* go visit five other hsdirs before giving up, which could result in a lot of thrashing. Whereas providing an old one will keep the client distracted for a while. But that's not really a good reason.

Another downside is that it's easier to stuff our cache full of things, i.e. use hsdirs for arbitrary storage of blobs for three days.

#15621 Kill the pre-version 3 intro protocol code with fire. Core Tor/Tor Tor: 0.2.??? enhancement Apr 7, 2015

We still have code for dealing with version 0, 1, and 2 of the HS intro protocol.

From rend-spec.txt:

As of Tor and, clients switched to using the v2 intro format.

From the release notes:

Bugfix on, when the v3 intro-point protocol (the first one which sent a timestamp field in the INTRODUCE2 cell) was introduced;

Anything that generates INTRODUCE cells with these versions are long dead, so the code for handling this protocol version should be removed.

#19024 prop224: Refactor rend_data_t so be able to use multiple HS version Core Tor/Tor Tor: 0.3.0.x-final enhancement May 10, 2016

Break rend_data_t into something that could looks like this (or maybe without a union...):

struct rend_data_t {
  uint32_t version; /* XXX: Maybe not necessary if our code flow doesn't
                     * require us to learn the version through that data struct. */
  union {
    hs_data_v2_t v2;
    hs_data_v3_t v3;
  } hs;

Once we have such construction, we can use v3 with that data structure more cleanly.

#6686 torouter IPv6 support Archived/Torouter enhancement Aug 24, 2012

This is a placeholder/discussion ticket for IPv6 support with torouter. IPv6 support is not a blocker or high priority at this time, and there is some concern about trusting "new" IPv6 daemons and code paths (citation needed!).

One way way IPv6 would work is that "downstream" devices connecting to the torouter (over the open wifi network or the local ethernet port) would auto-configure addresses from a site-local prefix (not globaly routed) and the torouter (via tsocks) would effectively provide NAT. With this scheme it would be possible to enable "downstream" IPv6 connectivity without proper "upstream" support (or vica versa).

"Upstream" IPv6 would require at least:

  • tor network and daemon support (roadmap)
  • ntp client support
  • automatic SLAAC/DHCPv6 configuration

Presumably SLAAC would use a randomized address (not based on the ethernet MAC address). Bootstrap upstream DNS could go straight to global DNS servers known to return both AAAA records and reply to requests over IPv6.

"Downstream" IPv6 would require at least:

  • a (hardened?) radvd
  • IPv6 configuration and support of the onboard recursive DNS servers (ttdnsd, unbound, dnsmasq)
  • support in tsocks
  • appropriate firewall rules
  • extension of the web interface to display and configure IPv6 options

In either case, kernel and iptable support would need to be enabled and the web interface extended to display and configure IPv6 options.

#6687 torouter dreamplug update to debian wheezy and 3.2 kernel Archived/Torouter enhancement Aug 24, 2012

wheezy (debian testing) probably be released in the next few months, so it seems reasonable to develop torouter for that target to ensure stability over the next few years. Also, several DreamPlug-specific changes were upstreamed into the mainline kernel and are present in wheezy.

AFAIK the required code changes would be updating the freedom-maker folder in torouter.git to a more recent version (either directly from b'dale or from nickdaly's version on github), redo source.list entries (backports not necessary?), and test that all required packages exist and function as expected under wheezy.

One road-blocker is that the more recent kernel seems to require an updated version of the u-boot bootloader on the DreamPlug, and the upgrade process requires the

The WiFi chipset still requires some third-party firmware and kernel module compilation (uap8xxx.ko == libertas_uap) with the 3.2 kernel.

#12823 Design and implement new deck format Metrics/Ooni enhancement Aug 7, 2014

The current test deck format has some limitations.

These are namely:

1) There is no way of making an input be part of the test deck itself

2) The format is too verbose and contains redundant information (all of the ooniprobe command line options need to be explicitly specified)

For this reason I think we should have a new format that makes it possible to include inputs as part of the test deck. The test deck should therefore be a compressed container (tar and gzip seem to be good candidates as they are well supported in python).

It should then be possible to reference input files that are part of the test deck itself.

Currently, the root path of the configured 'recent' directory is used when measuring the available space.

This might not make sense in situations when partitions are mounted elsewhere. For example:

/dev/sda1 on /      (just the os)
/dev/sdb1 on /data  (here the 'recent' folder resides somewhere)

In this case sda1 might be small and sdb1 could be the huge data partition. Thus, the measurement of free space for / is useless.

Suggestion: (cf. comments) Last resort: add CheckSpacePath property and default to the root of the recent path in case it doesn't exist.

#2424 Android purges firewall rules after network disable/airplane mode. Applications/Orbot defect Jan 22, 2011

Setting my phone to disable data access and/or enable airplane mode seems to cause the transproxy iptables rules created by OrBot to get silently flushed. After re-enabling, all apps access everything without tor, until I go into the orbot config screen to cause it to reapply them.

OrBot should listen for these network disable/loss/disconnect events if possible, and reinstate the iptables rules after this happens.

Someone should also test if switching from cell data to+from wifi also triggers this iptables reset. I have not tested that yet.

#3595 Connections with IPv4-mapped IPv6 addresses bypass transproxy Applications/Orbot defect Jul 14, 2011

A user (DEplan on #guardianproject) reported that Gibberbot was using his real IP despite Orbot's transproxy being turned on; further research led to the conclusion that recent releases of Android seem to use IPv4-mapped IPv6 adresses for a large portion of connections. For examples, please see http://pastebin.com/Z4KDDq40. These connections completely bypass transproxy.

I am not yet sure about the circumstances under which Android employs these addresses.

The problems in finding a solution are that Android usually does not include ip6tables (though Orbot could simply package that) and kernels do usually not include IPv6 netfilter modules. The latter is a major issue, since Orbot can't package modules for every single kernel a user might be running.

As a side note, IPv6 does not support NAT (which is what transproxying is based on).

I'll try to figure out what triggers this behaviour of Android and find possible solutions (using sysctl to disable IPv6 does not solve it).

#5393 orbot relay bug - orbot is not setting the relay values into torrc properly causing orbot to not work when set as relay Applications/Orbot defect Mar 15, 2012

This is about the bug discussed with 'n8fr8' on #guardianproject at freenode. So, the relay functionality you said was broken and needs to be fixed for 'orbot' on smartphones. I checked with the orbot version '' and you have checked with the 'dev branch of the code' as you said (i suppose that means you have checked with latest version of code by compiling and running the latest updated version from git; i will do it too and let you know again). But none seemed to work. In fact, you said you were getting a more significant crash, when you enabled relaying on smartphone for dev branch of code. You also thought if the problem is: whether the Relay conflict is with transproxying/root or with Tor client connection in general. But, i'm not sure if it later seemed not to be the problem. Then, you told me to change the torrc file on my android phone, as you said that orbot is not setting the relay values properly which might be the reason for orbot not working as a relay on smartphone. So, I will do that and let you know about it. I will also keep checking 'https://guardianproject.info/builds/Orbot/' to see if any new dev/debug release is posted. Thankyou so very much for all your help, Mr.Nathan.

#1749 Split relay and link crypto across multiple CPU cores Core Tor/Tor Tor: unspecified project Jul 29, 2010

Right now, Tor does nearly all of its work in one main thread. We have a basic "CPUWorker" implementation that we use for doing server-side onionskin crypto in a separate thread, but thanks to improvements long ago, server-side onionskin crypto on longer dominates. If we could split the work of relay AES-CTR crypto and SSL crypto across multiple threads, that would be pretty helpful in letting high-performance servers saturate their connections. (Blutmagie has wanted this for some while.)

#3428 Control port may emit log messages in the middle of another event/reply Core Tor/Tor Tor: unspecified defect Jun 18, 2011

If the following call to connection_printf_to_buf in handle_control_getinfo in src/or/control.c fails, it may emit a LOG control-port event in the middle of a reply:

    if (!strchr(v, '\n') && !strchr(v, '\r')) {
      connection_printf_to_buf(conn, "250-%s=", k);
      connection_write_str_to_buf(v, conn);
      connection_write_str_to_buf("\r\n", conn);
    } else {

I expect that other output functions can emit log messages in the middle of a control port event or reply, too. We should make sure that never happens, by making all control-port code build each complete reply/event in a separate buffer before writing any of it out, and adding an event/reply queue to the control_connection_t structure.

By commenting out "Sandbox 1" or unsetting it, tor will obviously run without crashing.

#18308 Tor threading broken Core Tor/Tor Tor: 0.2.??? defect Feb 12, 2016

Tor relies on double checked locking for various threading initializations. Double checked locking is not guaranteed to work.

For Posix: 4.11, Memory Synchronization: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html

Applications shall ensure that access to any memory location by more than one thread of control (threads or processes) is restricted such that no thread of control can read or modify a memory location while another thread of control may be modifying it.

#20406 compute_num_cpus() purports to clamp to 16, but doesn't. Core Tor/Tor Tor: 0.2.9.x-final defect Oct 19, 2016

Our compute_num_cpus() code is not supposed to report more than MAX_DETECTABLE_CPUS, since if you are somehow running Tor on a 64-core system, you should have to ask Tor before it decides to use all 64.

But it doesn't: the code logs a notice, and then does nothing.

This causes the following test failure on systems with more than 16 cores:

  FAIL ../src/test/test_util.c:3827: assert(num OP_LE 16): 18 vs 16

029 rationale: this is apparently making our tests fail in the debian reproducible build QA system.

#6836 Chop functionality out of routerlist.c Core Tor/Tor Tor: 0.2.??? enhancement Sep 13, 2012

In my branch "split_routerlist.c", I have the start of some work on dividing routerlist.c into more sensible pieces. I've chopped out routerset_t, killed a couple of functions, and moved most of the node manipulation pieces into nodelist.c

I'd still like to chop out more: the trusted_dir_server_t logic and the node-selection logic don't belong there any more. Nor does the authority certificate code. Nor does the hidden service directory stuff, nor does the hexdigest stuff.

In the longer term, I want routerlist.c to basically just not get invoked when you're not touching routerinfos.

#15426 Update ciphers.inc to match ciphers from current Firefox Core Tor/Tor Tor: 0.2.??? enhancement Mar 21, 2015

Firefox changed ciphersuits since we last updated ciphers.inc. We need to re-run get_mozilla_ciphers.py on the most recent stable Firefox and openssl, to generate a new ciphers.inc.

We should fix get_mozilla_ciphers if it needs it; the code may have rotted a bit.

#17295 Route-selection and guard-selection logic completely replaced Core Tor/Tor Tor: 0.3.0.x-final enhancement Oct 7, 2015

By Nov 2016, we have a deliverable to get our route selection much more right than today, and to have it very tested. We should get this done significantly earlier.

#449 dns failures prevent legitimate options being set Core Tor/Tor Tor: unspecified defect Jun 9, 2007

Outright hostname lookup failures for previously configured hidden services prevent other options being set while DNS is down.

For example, I configure a hidden service redirecting to google.com while DNS is working. DNS subsequently stops working, e.g. nameserver becomes completely unreachable. If I then attempt to set a config option using the controller, it will not get set as long as tor cannot resolve the hidden service name.

Rejection of hidden service configurations (and hence any subsequent or unrelated config change) made while tor is running needs to be more tolerant of lookup failures.

The following attempts to validate the hidden service config currently in use (and previously validated when DNS was working). If the validation fails, it must be because DNS is down, so the existing config is retained. If the user was attempting to add a new hidden service config, then it doesn't get added.

#4373 When we close a conn due to bad CERTS cell, we complain about stuff in our outbuf Core Tor/Tor Tor: unspecified defect Nov 1, 2011

While looking at bug #4371, here's what my client said:

Nov 01 04:30:45.000 [warn] Certificate not yet valid: is your system clock set incorrectly?
Nov 01 04:30:45.000 [warn] (certificate lifetime runs from Nov  1 12:15:08 2011 GMT through Oct 31 12:15:08 2012 GMT. Your time is Nov 01 08:30:45 2011 GMT.)
Nov 01 04:30:45.000 [notice] We stalled too much while trying to write 512 bytes to address "".  If this happens a lot, either something is wrong with your network connection, or something is wrong with theirs. (fd 14, type OR, state 7, marked at command.c:995).

Looks like we had already written our netinfo cell to the outbuf, but hadn't flushed it. Since I'm a client and this was an OR connection, it gets to be severity notice. Fun.

For the client side, I think this bug might be resolved by the proposed fix to #4361.

But my directory authority experiences something similar: Nov 01 06:04:10.000 [info] conn_close_if_marked(): Conn (addr "", fd 1609, type OR, state 7) marked, but wants to flush 916 bytes. (Marked at command.c:995) Nov 01 06:04:10.000 [info] conn_close_if_marked(): We stalled too much while trying to write 916 bytes to address "". If this happens a lot, either something is wrong with your network connection, or something is wrong with theirs. (fd 1609, type OR, state 7, marked at command.c:995). I wonder what's sitting in its outbuf.

#14987 Settle on a name for descriptors Core Tor/Tor Tor: 0.2.??? defect Feb 22, 2015

As discussed on #14784 we call self-published descriptors quite a few things...

  • 'GETINFO desc/*' and Stem call the main self-published descriptors server descriptors. Metrics also uses a "server-descriptor 1.0" annotation for them.
  • The dir-spec calls them router descriptors... usually. It opts for 'server descriptor' in section 6.2.
  • CollecTor calls them relay descriptors.

Having three different names is confusing for new contributors and... well, us too. We should standardize on a name.

This primarily straddles Tor's spec, Stem, and CollecTor. Personally I'd like for us to standardize on server descriptors because it's codified in the Metrics annotation and classes Stem vends.

Karsten, Nick: any objections? If not then I'm happy to provide a spec patch and file a CollecTor ticket for this.
