In 2.0, a call in loop to process_stream() + because the stream-interface remains blocked in the connect state + (SI_ST_CON). In both cases, it happens after a connection retry attempt. In 1.9, + it seems to not happen. But it may be just by chance or just because it is + harder to get right conditions to trigger the bug. However, reading the code, + the bug seems to exist too. + + Here is how the bug happens in 2.1. When we try to establish a new connection to + a server, the corresponding stream-interface is first set to the connect state + (SI_ST_CON). When the underlying connection is known to be connected (the flag + CO_FL_CONNECTED set), the stream-interface is switched to the ready state + (SI_ST_RDY). It is a transient state between the connect state (SI_ST_CON) and + the established state (SI_ST_EST). It must be handled on the next call to + process_stream(), which is responsible to operate the transition. During all + this time, errors can occur. A connection error or a client abort. The transient + state SI_ST_RDY was introduced to let a chance to process_stream() to catch + these errors before considering the connection as fully established. + Unfortunatly, if a read0 is catched in states SI_ST_CON or SI_ST_RDY, it is + possible to have a shutdown without transition to SI_ST_DIS (in fact, here, + SI_ST_CON is swichted to SI_ST_RDY). This happens if the request was fully + received and analyzed. In this case, the flag SI_FL_NOHALF is set on the backend + stream-interface. If an error is also reported during the connect, the behavior + is undefined because an error is returned to the client and a connection retry + is performed. So on the next connection attempt to the server, if another error + is reported, a client abort is detected. But the shutdown for writes was already + done. So the transition to the state SI_ST_DIS is impossible. We stay in the + state SI_ST_RDY. Because it is a transient state, we loop in process_stream() to + perform the transition. + + It is hard to understand how the bug happens reading the code and even harder to + explain. But there is a trivial way to hit the bug by sending h2 requests to a + server only speaking h1. For instance, with the following config : + + listen tst + bind *:80 + server www 127.0.0.1:8000 proto h2 # in reality, it is a HTTP/1.1 server + + It is a configuration error, but it is an easy way to observe the bug. Note it + may happen with a valid configuration. + + So, after a careful analyzis, it appears that si_cs_recv() should never be + called for a not fully established stream-interface. This way the connection + retries will be performed before reporting an error to the client. Thus, if a + shutdown is performed because a read0 is handled, the stream-interface is + inconditionnaly set to the transient state SI_ST_DIS. + + This patch must be backported to 2.0 and 1.9. However on these versions, this + patch reveals a design flaw about connections and a bad way to perform the + connection retries.
