Member Data Documentation

contiguous_len

uint32_t _fragment_head::contiguous_len

contiguous length from head up to first gap

datalen

uint32_t _fragment_head::datalen

When flags&FD_BLOCKSEQUENCE is set, the index of the last block (segments in datagram + 1); otherwise the number of bytes of the full datagram. Only valid in the first item of the fragments list when flags&FD_DATALEN is set.

error

const char* _fragment_head::error

Null if the reassembly had no error; non-null if it had an error, in which case it's the string for the error.

first_gap

struct _fragment_item* _fragment_head::first_gap

pointer to last fragment before first gap. NULL if there is no fragment starting at offset 0

flags

uint32_t _fragment_head::flags

XXX - do some of these apply only to reassembly heads and others only to fragments within a reassembly?

fragment_nr_offset

uint32_t _fragment_head::fragment_nr_offset

offset for frame numbering, for sequences, where the provided fragment number of the first fragment does not start with 0

frame

uint32_t _fragment_head::frame

maximum of all frame numbers added to reassembly

len

uint32_t _fragment_head::len

When flags&FD_BLOCKSEQUENCE and FD_DEFRAGMENTED are set, the number of bytes of the full datagram. Otherwise not valid.

reas_in_layer_num

uint8_t _fragment_head::reas_in_layer_num

The current "depth" or layer number in the current frame where reassembly was completed. Example: in SCTP there can be several data chunks and we want the reassembled tvb for the final segment only.

reassembled_in

uint32_t _fragment_head::reassembled_in

frame where this PDU was reassembled, only valid when FD_DEFRAGMENTED is set

ref_count

unsigned _fragment_head::ref_count

reference count in reassembled_table
