Subject: [PATCH 09/27] rtnl_link: fix off-by-one errors in indexed and sorted
|
|
xlat lookups
|
|
|
|
* rtnl_link.c (decode_nla_tun_type, decode_ifla_xdp_attached,
|
|
decode_ifla_inet_conf, decode_ifla_inet6_flags, decode_ifla_inet6_conf,
|
|
decode_ifla_inet6_stats, decode_ifla_inet6_icmp6_stats,
|
|
decode_ifla_inet6_agm): Decrement xlat size by one to account
|
|
for XLAT_END as other users of indexed and sorted xlats do.
|
|
|
|
Fixes: v4.25~71 "rtnl_link: decode named constants for IFLA_XDP_ATTACHED attribute value"
|
|
Fixes: v4.23~41 "rtnl_link: decode IFLA_AF_SPEC"
|
|
Fixes: v4.23~37 "rtnl_link: implement IFLA_INFO_DATA for tun devices"
