There was a race involving hlua_proxy_* functions and some proxy management functions. pause_proxy() and resume_proxy() can be used directly from lua code, but that could lead to some race as lua code didn't make sure PROXY_LOCK was owned before calling the proxy functions. This patch makes sure it won't happen again elsewhere in the code by locking PROXY_LOCK directly in resume and pause proxy functions so that it's not the caller's responsibility anymore. (based on stop_proxy() behavior that was already safe prior to the patch) This should be backported to stable series. Note that the API will likely differ < 2.4 (cherry picked from commit 7d00077fd5bd21e13aa976e6f3221cd44ae05eea) Signed-off-by: Christopher Faulet <cfaulet@haproxy.com>
