[Pkg-utopia-maintainers] Bug#1006271: network-manager: crashes if DHCPv6 server sends multiple IPv6 addresses

[Mad Horse]

Package: network-manager
Version: 1.35.91-1
Severity: important

Dear Maintainer,

network-manager 1.35.91-1 and 1.35.92-1 will abort if DHCPv6 server sends
multiple IPv6 addresses,( as under a default-configured openwrt router ) 
because
in this case, nm_dhcp_utils_merge_new_dhcp6_lease() would call
nm_l3_config_data_new_clone() with ifindex=-1, which may originally result
ifindex = src->ifindex; but now in order to make such effect, ifindex 
should be
set to 0 instead a negative value, otherwise such call will abort
network-manager for violating the assertion nm_assert(ifindex >= 0) in
nm_l3_config_data_new_clone().
