Unable to establish SSL connection about talos

[plaublin]

Hi

Thank you for raising this issue. This is due to a bug in the ssl_ctx_info_fake_cb(const SSL *ssl, int type, int val) function in ssl/ssl_lib.c. This function has not been updated correctly after we changed how the shadow structures mechanism stores objects.

This bug is fixed in commit 1ed1a18.

How did you build nginx, I am getting undefined references for sgx related function while doing make for nginx.

Hi gmatesunny, I followed the guide on the github. Did you link your sgx_sdk in the objs/Makefile?

in objs/nginx, for the LINK phase, update the following line with the correct path to libssl.a and libcrypto.a and add -lsgx_urts -lsgx_uae_service. Depending on how you compiled TaLoS, you may want to change -lsgx_urts -lsgx_uae_service (real hardware) to -lsgx_urts_sim -lsgx_uae_service_sim (simulator).

I resolved this problem but got to stuck with the following segmentation fault/enclave identification error.

Please see and I would be thankful if you could give some help on this:
