[NFS-Ganesha-Devel] Change in ...nfs-ganesha[next]: heap use after free for component_log_level

Suhrud Patankar has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/468729 ) Change subject: heap use after free for component_log_level ...................................................................... heap use after free for component_log_level In function log_conf_commit: 2568 if (component_log_level != default_log_levels) 2569 gsh_free(component_log_level); 2570 component_log_level = logger->comp_log_level; component_log_level is a global pointer. While the current thread is freeing and re-setting, If any other thread is accessing the pointer after execution of line 2569 but before 2570 is fully executed it will hit use-after-free case. Avoid changing component_log_level once set.
