+Subject: [PATCH] PROTON-1587: fix openssl error handling, causing spurious
+ errors
+
+From the SSL_get_error() man page:
+
+       In addition  to ssl and ret, SSL_get_error() inspects the current thread's OpenSSL error
+       queue.  Thus, SSL_get_error() must be used in the same thread that performed the TLS/SSL I/O
+       operation, and no other OpenSSL function calls should appear in between.  The current
+       thread's error queue must be empty before the TLS/SSL I/O operation is attempted, or
+       SSL_get_error() will not work reliably.
+
+Proton was not clearing the error queue, so the "shutdown-during-init"
+error (which was introduced recently in OpenSSL) was left dangling, and was
+reported incorrectly when the thread was used to serve another transport.

+Subject: [PATCH] src/ssl/openssl: add libressl compatibility
+
+Similar to https://github.com/FreeRDP/FreeRDP/issues/5049
+libressl has `#define OPENSSL_VERSION_NUMBER ` defined the same as
+openssl 1.1.x which results in SSL_CTX_set_security_level() getting used.
+
+This patch prevents SSL_CTX_set_security_level() from being used with
+libressl.
