[Bug 1951943] Re: Engine crashes when loading the configuration more than once

[Łukasz Zemczak]

Hello Dimitri, or anyone else affected,

Accepted openssl into hirsute-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/openssl/1.1.1j-1ubuntu3.6 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
hirsute to verification-done-hirsute. If it does not fix the bug for
you, please add a comment stating that, and change the tag to
verification-failed-hirsute. In either case, without details of your
testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: openssl (Ubuntu Hirsute)
       Status: In Progress => Fix Committed

** Tags added: verification-needed-hirsute

Bug description:
  [Impact]

   * Engine crashes when loading the configuration more than once

   * Upstream started to avoid loading engines twice by using dynamic
  ids to track the loaded engines correctly

   * OpenSSL 3
  https://github.com/openssl/openssl/commit/81c11349c2a0e945aa3dfc6bd81c957363dd2011 (bugfix)
  https://github.com/openssl/openssl/commit/38e2957249c90317a26a080c7e7eb186dd5b6598 (test case)

   * OpenSSL 1.1.1 backports:
  https://github.com/openssl/openssl/commit/9b06ebb1edfddffea083ba36090af7eb7cad207b (bugfix)
  https://github.com/openssl/openssl/pull/17083 (test case)

  [Test Plan]

   * https://github.com/openssl/openssl/issues/17023 lists multiple ways
  how one can trigger the issue at hand, but also test case implements
  this issue too by explicitly attempting to load an engine multiple
  times and checking that it is operational.

  The test a is run during the build as part of the upstream regression
  test suite, for the shared library build (as static build does not
  support engines), so you'll see one pass and one skip in the log.

  [Where problems could occur]

   * Separately we have started to fix userspace packages that
  needlessly load configuration files multiple times, which used to
  trigger this issue. The codepaths changed are with engine use, how
  they are loaded/unloaded/used. It is possible that this fix will make
  some engines to start working and be used resulting in new behaviour.
  But also exposing bugs in the engines that previously were installed &
  configured but not actually used.
