Hi,
following files still use tvb_new_real_data
./asn1/pkcs12/packet-pkcs12-template.c
leak memory, clear_tvb is never freed or attached to a parent tvb.
./asn1/kerberos/packet-kerberos-template.c
may leak memory, not all code paths call tvb_free(encr_tvb).
./epan/dissectors/packet-dcp-etsi.c
surely leak tvb structure memory.
./epan/dissectors/packet-cip.c
./epan/dissectors/packet-giop.c
Ok.
./epan/dissectors/packet-ssl-utils.c
leak tvb structure memory.
./epan/dissectors/packet-nfs.c
leak tvb structure memory.
./epan/dissectors/pidl/mapi/request.cnf.c
./epan/dissectors/pidl/mapi/response.cnf.c
ok but should use tvb_new_child_real_data().
./epan/dissectors/packet-rtmpt.c
may leak memory, anyway it uses tvb_composite_append() so it surely broken.
./epan/dissectors/packet-syslog.c
leak memory.
./epan/packet.c
./epan/ftypes/ftype-tvbuff.c
./epan/wslua/wslua_tvb.c
Ok.
./plugins/asn1/packet-asn1.c
leak and dissect a tvb buff in proto_reg_handoff() outside a TRY block.
./epan/tvbuff.c
ok but
./epan/dissectors/packet-dmp.c and ./epan/dissectors/packet-ldss.c use
tvb_uncompress and leak memory, should use tvb_child_uncompress
