Field Documentation

msg_uuid

struct MessageUUIDP ReassemblyContext::msg_uuid

Original message ID for of the message that all the fragments belong to.

Definition at line 1292 of file gnunet-service-transport.c.

Referenced by find_by_message_uuid(), free_reassembly_context(), and handle_fragment_box().

virtual_link

struct VirtualLink* ReassemblyContext::virtual_link

Which neighbour is this context for?

Definition at line 1297 of file gnunet-service-transport.c.

Referenced by free_reassembly_context(), and handle_fragment_box().

hn

struct GNUNET_CONTAINER_HeapNode* ReassemblyContext::hn

Entry in the reassembly heap (sorted by expiration).

Definition at line 1302 of file gnunet-service-transport.c.

Referenced by free_reassembly_context(), and handle_fragment_box().

bitfield

uint8_t* ReassemblyContext::bitfield

Bitfield with msg_size bits representing the positions where we have received fragments.

When we receive a fragment, we check the bits in bitfield before incrementing msg_missing.

Allocated after the reassembled message.

Definition at line 1311 of file gnunet-service-transport.c.

Referenced by handle_fragment_box().

reassembly_timeout

struct GNUNET_TIME_Absolute ReassemblyContext::reassembly_timeout

At what time will we give up reassembly of this message?

Definition at line 1316 of file gnunet-service-transport.c.

Referenced by handle_fragment_box(), and reassembly_cleanup_task().

last_frag

struct GNUNET_TIME_Absolute ReassemblyContext::last_frag

Time we received the last fragment.

avg_ack_delay must be incremented by now - last_frag multiplied by num_acks.

Definition at line 1322 of file gnunet-service-transport.c.

Referenced by handle_fragment_box().

msg_size

uint16_t ReassemblyContext::msg_size

How big is the message we are reassembling in total?

Definition at line 1327 of file gnunet-service-transport.c.

Referenced by handle_fragment_box().

msg_missing

uint16_t ReassemblyContext::msg_missing

How many bytes of the message are still missing? Defragmentation is complete when msg_missing == 0.

Definition at line 1333 of file gnunet-service-transport.c.

Referenced by handle_fragment_box().
