-PHASE #3: (Goal: ready for pre-release) [completion-goal: end of 2009]
-
-Module features to implement:
-* setup
- - default generation
- - need to settle basic design; do we want to keep guile?
-* tbench
- - good to have for DV evaluation!
-* tracekit
- - good to have for DV/DHT evaluation!
-* vpn
-
-
-GUIs to implement:
-* gtk
-* qt
-* fuse
-
-
-Plugins to implement:
-* UDP backend (need LIBRARY to support (de)fragmentation!)
-* HTTP backend
-
-
-
-
-
-Minor TODO items / known bugs:
-* UTIL:
- - crypto_hash: use libgcrypt (supports SHA-512 since 2003)
- - container_bloomfilter: improve efficiency (see FIXME)
-* SERVER:
- - inefficient memmove
-* TRANSPORT:
- - transport_api: support forcing disconnects through low quotas!
- (required for working F2F support!)
- - API: consider having core provide deadline information for each message
- (likely important for DV plugin which wants to loop back!)
- - implement transport API to pretty-print transport address
- + transport_api extension (API extension!)
- + service-transport extension (protocol extension)
- - add calls to statistics in various places
- - implement gnunet-transport (transport configurator / tester)
- - UPnP-based IP detection
- (Note: build library always, build service when libxml2/etc. are available)
- - instantly filter addresses from *other* peers that
- are *equal* to our own address + port (i.e., localhost:2086). We
- no longer filter those for outgoing (helps with loopback testing
- and keeps the code clean), but we should filter strictly *impossible*
- incoming addresses! This is for efficiency, not correctness.
- - We currently are happy to take any address told to us in a WELCOME
- to our set of addresses; we should have some minimal threshold-based
- scheme, limiting both the total number of addresses that we accept
- this way as well as requiring multiple confirmations; also, we
- should possibly try to confirm that the given address works for
- us ourselves (loopback-style) before adding it to the list
- [SECURITY issue]
- + we may be able to simplify WELCOME messages (no need to add
- addresses there anymore, but may help to learn them there anyway...).
- + we probably want some kind of voting/counting for learning IP addresses
- (maybe including IP addresses in ads proportional to how often others
- report them? we at least need some protection against >64k HELLOs!),
- + provide a way to give the user a list of "learned" IP addresses and
- a way to easily "veto" addresses off the list!
- => If MiM attacker uses vetoed address, blacklist the specific IP for
- the presumed neighbour!
- - not sure current way of doing ACKs works well-enough
- with unreliable transports where the ACK maybe lost;
- the "is_new" check would then possibly prevent future
- ACKs to be delivered, all while we're happily
- receiving messages from that peer! Worse, the other
- peer won't generate another ACK since it thinks we're
- connected just fine...
- Key questions:
- + How necessary is ACKing in the first place? (alternatives?)
- + Should we transmit ACKs in response to every HELLO? (would that
- fully address the problem?)
- - latency measurements implemented in the transport
- plugins makes it only work for bi-di transports
- and results in code replication
- - should latency be included in the ReceiveCallback and
- NotifyConnect or passed on request?
- - FIXME's with latency being simply set to 0 in a few places
- - Memory leak (running valgrind --trace-children=yes on test_transport_api:
- ==28393== 16 bytes in 1 blocks are indirectly lost in loss record 1 of 5
- ==28393== at 0x4C2260E: malloc (vg_replace_malloc.c:207)

- ==28393== by 0x524458A: GNUNET_NETWORK_socket_create_from_accept (network.c:289)

- And also:
- ==28393== 65,744 (65,728 direct, 16 indirect) bytes in 1 blocks are definitely lost in loss record 5 of 5
- ==28393== at 0x4C2260E: malloc (vg_replace_malloc.c:207)

- (rest of trace identical)
-
-* DATASTORE:
- - mysql backend
- - postgres backend
-* SETUP:
- - auto-generate "defaults.conf" using gnunet-setup from "config.scm"
- - integrate all options into "config.scm"
- - change config-file writing to exclude options set to default values
-* ARM:
- - implement exponential back-off for service restarts
- - better tracking of which config changes actually need to cause process restarts by ARM.
- - have way to specify dependencies between services (to manage ARM restarts better)
- - client-API is inefficient since it opens a TCP connection per service that is started
- (instead of re-using connections).
-* CORE:
- - code currently notifies clients about "encrypted" connections being up well before
- we get the encrypted PONG; sometimes this may be OK (for topology killing
- unwanted connnections), but of course not in general. I suspect we want
- to signal on PONG and have topology hook directly into transport to
- kill plaintext connections before they have a chance to become encrypted
- (may require minor hack in transport API)
-* PEERINFO:
- - have gnunet-peerinfo print actual host addresses again
- - add option to gnunet-peerinfo to modify trust value
-* POSTGRES-DB:
- - finish postgres implementation; simplify other SQLs using new stats
-* HTTPS transport
- - PolariSSL for MHD?
- - https integration
-* GAP improvements:
- - active reply route caching design & implementation of service,
- gap extension!
-* HOSTLIST:
- - implement advertising of hostlist URL
- - implement learning of hostlist URLs
-
