The updated openssl package does not change any behaviour w.r.t. config or engine use. It only has three patches applied to prevent potential use-after-free errors. It also relies on installing the new PKA engine with patches from github.
Has the new PKA engine been recompiled and installed correctly? When installed on my system, the engines configured continued to be used, and I can observe PKA debug output when using `openssl s_client -connect` or `curl`. Note, that `speed` command, by default does not use engines, even when configured in /etc/ssl/openssl.cnf. One must pass `-engine ID` option to it to use an engine. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssl in Ubuntu. https://bugs.launchpad.net/bugs/1921518 Title: OpenSSL "double free" error Status in openssl package in Ubuntu: Incomplete Status in openssl source package in Focal: Incomplete Bug description: "double free" error is seen when using curl utility. Error is from libcrypto.so which is part of the OpenSSL package. This happens only when OpenSSL is configured to use a dynamic engine. OpenSSL version is 1.1.1f The issue is not encountered if http://www.openssl.org/source/openssl-1.1.1f.tar.gz is used instead. OpenSSL can be configured to use a dynamic engine by editing the default openssl config file which is located at '/etc/ssl/openssl.cnf' on Ubuntu systems. On Bluefield systems, config diff to enable PKA dynamic engine, is as below: +openssl_conf = conf_section + # Extra OBJECT IDENTIFIER info: #oid_file = $ENV::HOME/.oid oid_section = new_oids +[ conf_section ] +engines = engine_section + +[ engine_section ] +bf = bf_section + +[ bf_section ] +engine_id=pka +dynamic_path=/usr/lib/aarch64-linux-gnu/engines-1.1/pka.so +init=0 + engine_id above refers to dynamic engine name/identifier. dynamic_path points to the .so file for the dynamic engine. # curl -O https://tpo.pe/pathogen.vim double free or corruption (out) Aborted (core dumped) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1921518/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
