HAProxy - Load balancer
1e8433f594
When a lua context is allocated, its stack must be initialized to NULL before attaching it to its owner (task, stream or applet). Otherwise, if the watchdog is fired before the stack is really created, that may lead to a segfault because we try to dump the traceback of an uninitialized lua stack. It is easy to trigger this bug if a lua script do a blocking call while another thread try to initialize a new lua context. Because of the global lua lock, the init is blocked before the stack creation. Of course, it only happens if the script is executed in the shared global context. This patch must be backported as far as 2.0. |
