feat: Due to the deep modifications related to names and packet format,
this task cover a large part of the codebase and involves several changes:
- the library provides a name data structure (hicn_name_t ), which is composed
of a name prefix (hicn_name_prefix_t) and a name suffix (hicn_name_suffix_t),
and it has been extended to provide all support functions required for name
manipulation, including common prefix computation, as required for the Longest
Prefix Match (LPM)in the forwarder, in addition to Exact Prefix Match (EPM).
- all code has been rewritten to use this data structure instead of having for
instance the forwarder define its own name class (used to be Name and NameBitVector)
the code has been refactored to minimize name allocations and copies, one remaining
aspect is the difference of name storage between PIT and CS entries (respectively
in the PIT entry, and in the message buffer), which causes the packet cache
index to be updated when a PIT entry is converted into a CS entry. By storing
the name in the PIT/CS entry everytime, we might save on this operation).
- hicn-light FIB has been rewritten : code has been refactored and should now be
shorter and documented; unit tests have been drafted but more would be required
to cover all cases and match the algorithms to add/remove nodes, as specified in the doc.
all protocol details and hICN header formats are now abstracted by the library
for the forwarder (and thus header.h and protocols/*.h have been removed from
public includes, and replaced by packet.h providing protocol agnostic packet
level functions, completely replacing the compat.h header that used to provide
similar functions.
- this works by exposing a opaque buffer to the application (a kind of socket buffer)
which is used by the lib to cache the packet format and offsets of the different
layers in the buffer and provider efficient operations (the packet format is
either defined for packet construction, or guessed at ingress, and this structure
is updated accordingly only once).
