From f4cea62ed95e4967d8591f25e903f5e8fc2e2a30 Mon Sep 17 00:00:00 2001

Subject: [PATCH] BUILD(crypto): Migrate to OpenSSL 3.0-compatible API
OpenSSL 3.0 deprecated several low-level APIs and the usage of them
caused errors/warnings that prevent the binary from being built against
OpenSSL 3.0.
Some primitive efforts have been made in #5317 but were incomplete.
This commit follows https://www.openssl.org/docs/man3.0/man7/migration_guide.html,
https://code.woboq.org/qt6/qtopcua/src/opcua/x509/qopcuakeypair_openssl.cpp.html,
and clears all errors/warnings related to the usage of deprecated APIs.
Fixes #5277
Fixes #4266

Subject: [PATCH] FIX(crypto): Sharing EVP context between threads crushes
Mumble
Functions ocb_encrypt and ocb_decrypt share the same set
of encrypt and decrypt contexts. However, they are invoked
in different threads (audio input thread and server
handler thread).
This may lead to conflicts that would crash Mumble.
This patch separates contexts used in these two functions
to avoid such conflicts.
Fixes #5361

Subject: [PATCH] FIX(client): PipeWire crash
When destroying the PipeWire object we first destroyed the thread loop
and then the stream, but this has to be done in reverse order in order
to avoid crashes.
Fixes #6101
