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
