* extra: pktbuff: pktb_expand_tail return 0 if there is no room in the tailPablo Neira Ayuso2012-08-201-3/+9
| | | | | | | | | | | | pktb_expand_tail returns 0 if there is no room for the mangling. Note that we don't support dynamic reallocation, instead the caller is responsible for allocating the extra room via pktb_alloc according to the maximum amount of bytes it needs for the mangling. Since pkt_buff layout is not exposed, we can change this in the future if we prefer dynamic reallocation. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
