HAProxy - Load balancer
During SPOP healthchecks, a dummy appctx is used to create the HAPROXY-HELLO frame and then to parse the AGENT-HELLO frame. No agent are attached to it. So it is important to not rely on an agent during these stages. When HAPROXY-HELLO frame is created, there is no problem, all accesses to an agent are guarded. This is not true during the parsing of the AGENT-HELLO frame. Thus, it is possible to crash HAProxy with a SPOA declaring the async or the pipelining capability during a healthcheck. This patch must be backported to 1.9 and 1.8. |
