After compiling pquic on Ubuntu 16.04 using the guide on https://pquic.org/, picoquicdemo quits with a segmentation fault.

The used versions of openssl and libarchive are as follows: OpenSSL_VERSION: 1.0.2g libarchive_version: 3.4.0

Could you run it again with GDB so that we get a trace of the error ?

We use OpenSSL 1.1.x actually. Upgrading your lib version might fix this issue. On Ubuntu 16.04, you might have to compile it yourself since there is no official package. I will add this requirement to the doc.

Unfortunately, upgrading to OpenSSL 1.1.1 does not help. I also re-compiled LibArchive to use openSSL 1.1.1. In this case, the client dies with a segmentation fault before sending any data to the server: Segfaul occurs in picoTLS line 953, when ctx->do_init(ctx, iv) is called and do_init is NULL.

Segfaul occurs in picoTLS line 953, when ctx->do_init(ctx, iv) is called and do_init is NULL.

That was my guess too. Ok I got it, it was very clear from the GDB trace.

#2 picoquic_pn_encrypt (pn_enc=0x6a3000, iv=, output=0x7fffffffcd39, input=0x7fffffffcd39, len=4) at /home/wte2hi/ccu/pquic/pquic/picoquic/tls_api.c:1351

In particular #3 ... picoquic_protect_packet(..., pn_enc=0x6a3070) and then later #2 picoquic_pn_encrypt (pn_enc=0x6a3000, ...). This is a very odd compiler bug I faced with old versions of GCC (mine was 3.7 something), what is yours ? Clang works fine for compiling the PQUIC core as well.

wette commented 4 years ago

i have gcc version 5.4.0 installed. How do i tell cmake to use clang? exporting CC and CXX does not work (but i'm not sure, why).

It should, see https://stackoverflow.com/a/7032021. Otherwise look at Ubuntu's update-alternatives, but it's system-wide so it's not ideal.

adarshdec23 commented 4 years ago

Faced a problem with core dumps. The following worked:

To prevent a global config change with the compilers run cmake and make as:

cmake -DCMAKE_C_COMPILER=/path/to/clang
make -CC=/path/to/clang
mpiraux commented 4 years ago

I close this issue as it seems that no further assistance is needed.
