From f7fa16d49837f947ee59492958f9e6f0e51d9a78 Mon Sep 17 00:00:00 2001 From: Sabrina Dubroca Date: Wed, 28 Feb 2024 23:43:57 +0100 Subject: tls: decrement decrypt_pending if no async completion will be called With mixed sync/async decryption, or failures of crypto_aead_decrypt, we increment decrypt_pending but we never do the corresponding decrement since tls_decrypt_done will not be called. In this case, we should decrement decrypt_pending immediately to avoid getting stuck. For example, the prequeue prequeue test gets stuck with mixed modes (one async decrypt + one sync decrypt).
