LGTM It's a common problem with nvlists-in-nvlists, and it's not the first time it's caught me. |

There was a problem hiding this comment.
remove_nvl is not remote_nvl, so this won't work :-) - I've replied by mail to the list post, and asked for a v2 there.

Some memory leaks were detected by valgrind on the openvpn daemon, using DCO mode on a FreeBSD platform. The leaks are caused by missing nvlist_destroy calls in the file dco_freebsd.c. Calls to nvlist_destroy were added, sometimes using local variables to store nvlist pointers temporarly. A valgrind run on the updated daemon confirmed that the leaks were gone.

Some memory leaks were detected by valgrind on the openvpn daemon, using DCO mode on a FreeBSD platform.
The leaks are caused by missing nvlist_destroy calls in the file dco_freebsd.c.
Patch content
Calls to nvlist_destroy were added, sometimes using local variables to store nvlist pointers temporarly.
A valgrind run on the updated daemon confirmed that the leaks were gone.
