Description Ralf Ertzinger 2022-05-19 09:59:43 UTC 
Created attachment 1881276 [details]
packet capture from a F36 system running the HTTPS example code

Description of problem:
Using tcltls on F36 with openssl 3.0 produces garbage on the wire, causing handshakes to fail.


Version-Release number of selected component (if applicable):
tcltls-1.7.22-5.fc36

How reproducible:
Always

Steps to Reproduce:
Using the example from https://core.tcl-lang.org/tcltls/wiki?name=Documentation#HTTPS%20EXAMPLE in tclsh:

On a F35 system:
% package require http
2.9.1
% package require tls
1.7.22
% http::register https 443 [list ::tls::socket -autoservername true -require true -cadir /etc/ssl/certs]
443 {::tls::socket -autoservername true -require true -cadir /etc/ssl/certs}
% set tok [http::geturl https://www.tcl.tk/]
::http::1



On a F36 system:
% package require http
2.9.5
% package require tls
1.7.22
% http::register https 443 [list ::tls::socket -autoservername true -require true -cadir /etc/ssl/certs]
443 {::tls::socket -autoservername true -require true -cadir /etc/ssl/certs}
% set tok [http::geturl https://www.tcl.tk/]
failed to use socket



Looking at a packet capture, whatever goes out on the wire does not look like a TLS handshake. A TLS handshake should start with 0x16 (CLIENT HELLO), the data sent by tcltls on F36 starts with 0x01. A pcap is attached.
