Acked-by: Gert Doering <gert@greenie.muc.de> This one is fairly straightforward (and the leak is small) - I've re-read all the code involved for v2 of the patch (set) and the change is correct. The device name involved stays unchanged in the current iterations of open_tun_dco(), so there is no need to save it there (fallout of the many rewrites of these parts). Your patch has been applied to the master and release/2.6 branch. commit 021952705ba4b77a1d94bec85f6f02e6c612a37e (master) commit be7a5640fbce2d3d56bdcee23e3d76ea15a678d1 (release/2.6) Author: Arne Schwabe Date: Tue Mar 14 15:48:54 2023 +0100 Fix memory leaks in dco open tun Signed-off-by: Arne Schwabe <arne@rfc2549.org> Acked-by: Gert Doering <gert@greenie.muc.de> Message-Id: <20230314144854.182110-2-arne@rfc2549.org> URL: https://www.mail-archive.com/openvpn-devel@lists.sourceforge.net/msg26411.html Signed-off-by: Gert Doering <gert@greenie.muc.de> -- kind regards, Gert Doering

The open_tun_dco_generic already allocates the actual_name string, this shadows the allocation in the FreeBSD/Linux specific methods.
