Re: TLS connect error: "an EOF was observed that violates the protocol"

by Rodrigo Arias

Hi, I think there are two problems here: 1) The narkive server is sending you an EOF but not us. 2) When that happens Dillo crashes. You may be able to get some info on where it is failing by building Dillo with the address sanitizer enabled: $ git clone https://github.com/dillo-browser/dillo $ cd dillo $ ./autogen.sh $ mkdir build $ cd build $ ../configure 'CFLAGS=-Og -g -fsanitize=address' 'CXXFLAGS=-Og -g -fsanitize=address' $ make $ src/dillo https://narkive.com Then send *all the lines of the output*. I may be able to emulate an EOF and crash my own Dillo just to reproduce the issue with this information. To debug the TLS traffic you may want to get a network trace with Wireshark so we can compare it. Best, Rodrigo.

I have enabled DEBUG_PACKAGES in dillo, which unfortunately wasn't done before. Once the debug-dillo package is available (will be a few days), we might get some more insight from a backtrace with symbols... If you have a ports tree set up (with doas, etc) you can build and install it yourself: $ cd /usr/ports/www/dillo $ grep DEBUG Makefile # ensure that your tree's up-to-date DEBUG_PACKAGES = ${BUILD_PACKAGES} $ make FETCH_PACKAGES= prepare $ make package $ make INSTALL_DEBUG_PACKAGES=yes install

My nc output matches yours, but ftp still gets the handshake failure. Maybe it's something network specific on my end? But like I mentioned, an older OpenBSD system on my network with LibreSSL 3.6.0 does not have an issue with that site. I disabled pf just in case, but to no avail. I'm open to any clues on how to diagnose this! Regards, Alex

It's a bit unfortunate, but the development release on current openbsd snapshots still has 3.9.0 as the version number. It's complicated... The short story is that we can't crank to 4.0.0 because it would break the build of some important ports (e.g., rust). > Anyway, I installed 3.9.2 from source and built Dillo against that. > Now it reports the correct version, but the crash still happens the > same. > > I guess we would need to hear from some other OpenBSD users to confirm > if this a real issue, or if its something whacky on my end. > > I do have an older OpenBSD system which uses LibreSSL 3.6.0, and it does > not exhibit the problem.
