Change h1_process() to return -2 when the mux is destroyed but the connection is not, so that we can differentiate between "both mux and connection were destroyed" and "only the mux was destroyed". It can happen that only the mux gets destroyed, and the connection is still alive, if we did upgrade it to HTTP/2. In h1_wake(), if the connection is alive, then return 0, as the wake methods should only return -1 if the connection is dead. This fixes a bug where the ssl xprt would consider the connection destroyed, and thus would consider its tasklet should die, and return NULL, and its TASK_RUNNING flag would never be removed, leading to an infinite loop later on. This would happen anytime an HTTP/2 upgrade was successful. This should be backported up to 2.8. While the bug by commit 00f43b7c8b136515653bcb2fc014b0832ec32d61, it was not triggered before only by chance, and exists in previous releases too. |
