HAProxy - Load balancer
d4835a9680
When updating from 2.4 to 2.6, the child->reloads++ instruction changed place, resulting in a former worker from the 2.4 process, still identified as a current worker once in 2.6, because its reload counter is still 0. Unfortunately this counter is used to chose the mworker_proc structure that will be used for the new worker. What happens next, is that the mworker_proc structure of the previous process is selected, and this one has ipc_fd[1] set to -1, because this structure was supposed to be in the master. The process then forks, and mworker_sockpair_register_per_thread() tries to register ipc_fd[1] which is set to -1, instead of the fd of the new socketpair. This patch fixes the issue by checking if child->pid is equal to -1 when selecting proc_self. This way we could be sure it wasn't a previous process. Should fix issue #1785. This must be backported as far as 2.4 to fix the issue related to the reload computation difference. However backporting it in every stable branch will enforce the reload process. |
