tx_tlp conn.c:468 ABORT: assertion failed
Here's a log with an assertion failure. I can't tell what's going wrong here. It seems like maybe trying to send data on a stream that doesn't exist?

hardcoded path in the server
The path /Users/lars/Sites/lars/output is hardcoded in the server.
Proper congestion control
Packets not recognized by Wireshark
All traffic between client and server is interpreted as normal UDP.
Forcing Wireshark to decode the packets as QUIC, results in various errors.
E.g.:
> Expert Info (Note/Protocol): Unknown QUIC connection. Missing Initial Packet or migrated connection?
> Expert Info (Warning/Decryption): Failed to create decryption context: Decryption (checktag) failed: Checksum error
> Expert Info (Warning/Decryption): Failed to create decryption context: Unable to retrieve cipher information
> Expert Info (Warning/Decryption): Failed to decrypt packet number
Question about 0-RTT
Hi,
I'm playing around with your library for my bachelor thesis and wanted to ask if it is possible to get the server response in the first Handshake during an 0-RTT connection.
At the moment the client is sending the request in the 0-RTT packet. The server is answering this packet with his Handshake packet, containing the ServerHello, Encrypted Extensions and the TLS 1.3 Finished. After this the server sends his Session Ticket and only now it sends the request to the client.
I have read in the IETF draft that it is possible the send the response in the first Handshake packet. So is there a way with your lib to do it?
Thanks for your answer in advance.

Received Invalid Padding When Connecting to quant.eggert.org
When I try to connect to quant.eggert.org:4433 the server is sending back an improperly formatted packet. The first frame is an ACK frame that correctly ACKs the ClientInitial, but the second frame is PADDING, with only the first part of it being all zeros. I am guessing that it is possible a STREAM frame is getting put somewhere after the PADDING. The full logs for the initial response from https://quant.eggert.org/:

Issue in building quant
Hi,
I'm trying to build the quant on Fedora. After running 'make' command, I'm facing the following issue.
Please guide me in this.
I already have all the header files of openssl but somehow it's unable to link them to quant/picotls.

ev_async_stop is not called in free_conn
free_conn (https://github.com/NTAP/quant/blob/14/lib/src/conn.c#L1287) does not call ev_async_stop prior to freeing the ev_async (https://github.com/NTAP/quant/blob/14/lib/src/conn.c#L1326).
However, it is initialized in new_conn (https://github.com/NTAP/quant/blob/14/lib/src/conn.c#L1247) with a value inside the conn that is free'd, so there is now a dangling pointer inside the loop.
This doesn't crash because it's an async watcher, and it never gets triggered again, and it seems that libev never looks at it again too closely, or otherwise it would touch upon free'd memory.
This behavior was detected using techniques developed by the SYMBIOSYS research project at COMSYS, RWTH Aachen University. This research is supported by the European Research Council (ERC) under the EU's Horizon 2020 Research and Innovation Programme grant agreement n. 647295 (SYMBIOSYS).
out of bound array access
Line 1057 in d3dd6c8
Hi,
This is a duplicate. I also created this issue in the master branch.
do {
X509 * const x509 = PEM_read_X509(fp, 0, 0, 0);
if (x509 == 0)
break;
tls_certs[i].len = (size_t)i2d_X509(x509, &tls_certs[i].base);
X509_free(x509);
} while (i++ < TLS_MAX_CERTS);
this code fragment may crash the application. i++ increments the variable after the comparison. This may mean, that i can hold the value TLS_MAX_CERTS and thus cause the application to crash.
Best Regards

cannot build netmap based quant
Hi Lars,
I installed netmap and it works fine. But after executing make, only client and server based on socket can be generated. How can we leverage warpcore on quant? or how can we generate both socket and warpcore based quant at the same time?
Thanks in advance!

performance: transfer rate decreases over time
Hello,
I ran a simple benchmark test between two machines in LAN with the latest master branch (release build) with the socket backend, and observed the rate started at ~400Mbps but then dropped quickly to ~90Mbps during the first few seconds.
perf report on the server shows these hot functions:
perf report -U
# Children Self Command Shared Object Symbol
35.72% 35.57% server server [.] pm_by_nr(_splay)
|
---pm_by_nr(_splay)
28.90% 28.79% server server [.] find_sent_pkt
|
---find_sent_pkt
17.43% 17.35% server server [.] diet_find
|
---diet_find
Might that be related to the inflation of un-acked data ranges on the sending side?
By the way, I hit the limit of ~100MB transfer size (complained by either w_iov_sq_len() or w_alloc_iov()), does this also happen with netmap or is there any workaround?
Thanks,
Hoang

launching multiple connections with the same server.
Hi, is it possible to establish multiple connections (e.g., 20 cones) with the same server (i.e. with the same interface and port) for multiple clients using the current version? If so, what cmd do I have to use? Thanks.
client-warp failed with errno 2
Hi,
I connected 2 servers back to back. And start the client-warp on one server. But it exited with log like this
# ./bin/client-warp -i ens3f0 http://192.168.0.1:5599/output.dat

and I also ran client with a socket version. It worked just fine. The problem only exists in the netmap version.
How should I proceed?
Thanks,
Get socket-handle
Hi!
We are thinking about using this quic-stack in a C++-Framework. Since our network-design depends on epoll and the resulting events that come with it we need to be able to get the socket-handle.
I was looking around the interface and couldn't find such a function to get the created handle from the lib/warpcore-stack. Is there any way that I'm missing, or is it really not possible to get the handle?
APPLICATION_CLOSE sent in initial packet
I am currently working on a specification-based compliance tester for QUIC. The tester turned up the following behavior of the quant server that appears not to conform to specification draft 15/16.
In this execution, an http parse error occurs (because the tester is sending random data on a stream). Quant sends an application close frame inside an intial packet, which appears not to be allowed by the
spec. The spec says:
The payload of an Initial packet includes a CRYPTO frame (or frames)
containing a cryptographic handshake message, ACK frames, or both.
PADDING and CONNECTION_CLOSE frames are also permitted. An endpoint
that receives an Initial packet containing other frames can either
discard the packet as spurious or treat it as a connection error.
This appears to indicate that an APPLICATION_CLOSE frame occurring in an initial packet is a protocol error.
Here is the log output produced by quant in this test case:

Server sends packets to new address without highest packet number
Here is a case where the server sends a non-probing packet to a new
address, though the packet received from the new address does not have
the highest packet number received.
In the server log, the source IP addresses are not shown. The packets from
the new IP address are at the following times:
2.682
2.956
Neither of these packets has a largest packet number. The largest packet
number at the time is 8, from the packet received at 1.688.
The packet sent by the server to the new address is a handshake packet
at time 2.682, whish seems to be in response to the first packet from
the new address.
This behavior violates the following requirement from section 9.3 of
draft-16:
An endpoint only changes the address that it sends packets to in
response to the highest-numbered non-probing packet.
Also, the server sends a rapid sequence of packets to the new address,
which might violate this provision:
An endpoint MAY send data to an unvalidated peer address, but it MUST
protect against potential attacks as described in Section 9.3.1

Client example missing "-l" parameter
The client example in bin returns the following when using the -l log option:
[belbs@helheim bin]$ ./client -l /tmp/test index.html
./client: invalid option -- 'l'
client [options] URL
[-i interface] interface to run over; default lo
[-s cache] TLS 0-RTT state cache; default /tmp/test
[-l log] log file for TLS keys; default /tmp/quant-tlslog
[-t timeout] idle timeout in seconds; default 1
[-c] verify TLS certificates; default false
[-u] update TLS keys; default false
[-3] send a static H3 request; default false
The problem seems to be located in the client.c file:
Line 270 in a738ea9
Adding
l: to the getopt option string results in correct behaviour.ABORT: assertion failed / must not TX while draining
This assertion failure occurred while serving multiple HTTP requests in the same QUIC packet. The repro is a little complicated, because it requires the application (the http server) to be slow.
Here are the requests being served:
GET /5
GET /3
GET /index.html
An idle timeout appears to occur while the first request is being served. The happened because I was stepping through the http parser code in the debugger, but in principle I think it could happen because the application is slow for any reason. The server continues to parse requests, however. The second request causes an attempt to send three bytes on the stream, which results in the assertion failure.
Note, I modified line 139 of server.c to the following to cause it not to send the FIN bit after every request, but I don't know if this is relevant:
q_write(d->s, &out, false);
The complete log output of the server showing the assertion failure follows:

PATH_CHALLENGE continues while connection in closed state.
This server log shows a case where the client stops communicating. The connection enters the draining and then closed states after an idle timeout, however the server continues to send ACK and PATH_CHALLENGE frames. This first occurs at 88.046, and subsequently at increasing intervals. To obtain this trace, server.c was modified to use blocking read rather than non-blocking, allowing it to continue to serve requests. The likely cause seems to be that alarms were not cancelled when the connection entered the closed state.

Issue only when redirecting server output to a file
Hello,
I don't know if this is due to my lack of sleep or it is a real issue.
When I run quant server (latest commit afc00e9, Debug mode) with no output redirection, it works:
./bin/server -d /dev/shm/ -b 500000
When I run it with redirection:
./bin/server -d /dev/shm/ -b 500000 &> /tmp/quant-server-log
, the connection was established but then does not work, you can see the output here (view it colorfully with less -R):
server.log
And it seems Release mode does not work either.
Is there any possibility some file descriptor got messed up in my case?
Thanks,
empty version negotiation packet
When hitting the public endpoint with an unsupported version, I'm getting an empty version negotiation packet (17 bytes long, which means the header seems correct, but it contains no versions at all).
Memory fault on RST_STREAM of closed stream

heap use after free: based on commit 93d6363dac63fd37da52e7370d83fd81a634b9d4
I ran into this error when testing commit 93d6363 of the implementation. I haven't been able to test it for the latest version of the implementation as I was using a custom client which doesn't support the latest version yet.

CLOSE_CONNECTION on PATH_RESPONSE from wrong address
In this log, the following events occur:
- server sends PATH_CHALLENGE(X) to address A
- A responds with PATH_RESPONSE(X)
- server sends PATH_CHALLENGE(Y) to address B
- B responds with PATH_RESPONSE(X)
- server closes connection with error 0xa
I don't think (5) is forbidden, but it doesn't seem to be a good idea, since (4) could be a replay by an adversary of a delayed PATH_RESPONSE. It seems better to ignore PATH_RESPONSE frames with unexpected values and abandon the path challenge when it times out.
You might be able to repro this with the following docker container: kenmcmil/quictest:v0.9
The symptom is:
quic_server_test.ivy: line 513: error: assumption failed
It occurs fairly frequently in my tests.

When receiving an initial packet with version 0xff000010, the quant server seems to run into some kind of problem sending a Retry packet. There are also some reports of misaligned accesses, but I don't know if these are relevant. Here is the log:

q_close_stream not working as intended?
The example server and client work fine for me (branch 14).
However, when I change all q_write*s to q_close_streams in the example server (see send_err and serve_cb here), they start behaving weird.
Ultimately the client runs into a timeout in q_readall_str and closes the connection. However, while the client is "waiting" for the timeout, the server's RTO alarm is firing every 0.010 seconds.
It seems to me that something is going wrong here. My suggestion would be that somehow the server is not sending out a FIN to the client here. Since it works fine when the FIN is sent together with actual data (as is the case in the unmodified example), maybe no FIN is sent when there is no other data to send? Is this actually intended behavior? If so, this behavior would be very non-obvious from looking at the API.
This behavior was detected in the course of the SYMBIOSYS research project at COMSYS, RWTH Aachen University. This research is supported by the European Research Council (ERC) under the EU's Horizon 2020 Research and Innovation Programme grant agreement n. 647295 (SYMBIOSYS).
Threadsafety question
Hello! Thanks for your excellent work!
I'm trying to use your library in my project, and I have a question: is quant library thread-safe in any degree ?
Should I use external locking on q_bind\q_ready\q_accept (or any other) methods ? Can I run multiple independent server instances simultaneously, produced with multiple q_init calls ?
cmake runs successfully however the make after that fails with the following error(running on ubuntu 18.04 WSL) :-

Hi,
do {
X509 * const x509 = PEM_read_X509(fp, 0, 0, 0);
if (x509 == 0)
break;
tls_certs[i].len = (size_t)i2d_X509(x509, &tls_certs[i].base);
X509_free(x509);
} while (i++ < TLS_MAX_CERTS);
this code fragment may crash the application. i++ increments the variable after the comparison. This may mean, that i can hold the value TLS_MAX_CERTS and thus cause the application to crash.
Best Regards
launching multiple instances on the same server
Hi,
I was planning to run both server-warp and client-warp on the same machine.
The server was launched using:
/bin/server-warp -i ens3f0 -p 5599
and the client with:
./bin/client-warp -b 10000000 -r 10 -i ens3f1 http://192.168.0.2:5599/100000000
But after executing the cmds above, the client-warp throws the error:
0.004 :0 ABORT: DIED [errno 12 = Cannot allocate memory]

Fails to open a bidirectional stream on STOP_SENDING
It looks like quant is not opening bidirectional streams on receipt of STOP_SENDING, per the change in draft-17. Here is the relevant language:
An endpoint opens a bidirectional stream when a MAX_STREAM_DATA or STOP_SENDING
frame is received from the peer for that stream. Receiving a MAX_STREAM_DATA
frame for an unopened stream indicates that the remote peer has opened the
stream and is providing flow control credit. Receiving a STOP_SENDING frame for
an unopened stream indicates that the remote peer no longer wishes to receive
data on this stream. Either frame might arrive before a STREAM or
STREAM_DATA_BLOCKED frame if packets are lost or reordered.
I haven't checked whether it opens streams on MAX_STREAM_DATA.
Here' s log showing the receipt of STOP_SENDING on stream 4 at 18.579:
