2013-11-17Assoc's array is now allocated dynamically and per default much smaller (320 ↵Coren[m]
entries). id_hash() was not at all working as expected for very small bucket size (when (size / 4) was zero). Simplified to be trivially correct. Also added a used flag on adding an entry, which is set by callers if they have that association in active use. Those get priority over unused entries on collision. Fleshed out test to be at least elementary useful. Each group chat now uses an own, small assoc (80 entries).
2013-11-14Significantly trimmed down version of an ID<=>IP cache.Coren[m]
Besides acknowledging timeouts, the module isn't trying to do anything fancy with the data besides storing and retrieving.
2013-11-14On replacing a client with another, clear the stale association.Coren[m]
Also check both associations for timeout, not just the incoming one. Also removed client_in_list(): static & unused.
2013-11-10Fixed small issues.irungentoo
DHT_test now only prints non zero entries.
2013-11-10Added more printing to DHT_test, fixed typo.irungentoo

2013-11-07Merge branch 'add2lists_forward' of ↵irungentoo
https://github.com/FullName/ProjectTox-Core into FullName-add2lists_forward
2013-11-06Unify most of handle_sendnodes[_ipv6]() into a common ↵Coren[m]
handle_sendnodes_core(), leave only a minimal trail.
2013-11-06addto_lists(): store the IP/Port that was used to *send*.Coren[m]
Avoids a DOS of sending a copy of a valid response with an invalid IP.
2013-11-02Get node testing response packets are now handled.irungentoo
2013-10-30Testing requests are now sent.irungentoo
2013-10-28Merge branch 'master' into hardenirungentoo
Also removed some old, useless loading code.
2013-10-28Removed some now useless code.irungentoo
2013-10-27Added some hardening functions to test get nodes.irungentoo
2013-10-26Base of hardening stuff.irungentoo
2013-10-24Removed now useless ping_id from send/get node packets.irungentoo
2013-10-24Adding encrypted data to send/getnode packets now done.irungentoo
2013-10-24Move unix_time(), id_cpy()/id_eq(), is_timeout() to util.*Coren[m]
unix_time(): - returns local value for current epoch - value is updated explicitly with unix_time_update() called at new_DHT()/doMessenger()/do_DHT() is_timeout(): - uses the local value for current epoch id_cpy()/id_eq() => id_copy()/id_equal(): - centralized duplicate definitions - replaced (most) memcpy()/memcmp() of (*, *, CLIENT_ID_SIZE) with id_copy()/id_equal()
2013-10-24Adding encrypted data to send/getnode packets part 1.irungentoo
2013-10-24Removed define that could become confusing.irungentoo
2013-10-20Main: Eliminate TOX_ENABLE_IPV6 (then always on), CLIENT_ONETOONE_IP (then ↵Coren[m]
always off). Additionally (besides cleanups): network.h/tox.h: - WIN32: fix a strange sa_family_t definition - WIN32: define EWOULDBLOCK to WSAEWOULDBLOCK - WIN32: kill macro for an existing function (IN6_ADDR_EQUAL) network.c: - use EWOULDBLOCK instead of EAGAIN (same value, but EWOULDBLOCK is more "popular") - new_networking(): only try to enable IPv4-in-IPv6 if it's not already enabled per default - inet_ntop()/inet_pton(): WIN32: remove partial initializers in favor of a simple memset() - ip_equal(): WIN32: use an existing function - logging: networking_wait_execute(): only dump result if not timeout - logging: loglogdata(): kill an unused variable LAN_discovery.c: - send_broadcasts(): re-enabled, can only support IPv4 by principle, split into fetch_broadcast_info() (to fetch the addresses once) and send_broadcasts() (actual sending) DHT.c: - DHT_load_state_callback(): enclosed a fprintf(stderr, ...) into #ifdef DEBUG Lossless_UDP.c: - change_handshake(): harden against strange sa_family_t definitions Messenger.c: - logging: fix ID to string conversion util.c: - logging: eliminate a signed-warning
2013-10-12Improved hole punching.irungentoo
2013-09-30Speeded up/fixed NAT hole punching and peer finding.irungentoo
2013-09-28Fixed small issue.irungentoo
2013-09-28Behaviour with LAN ips is now better, also fixed possible bug.irungentoo
2013-09-28LAN ips can be sent to LAN ips.irungentoo
2013-09-28friend_iplist and route_tofriend behaviour fixes.irungentoo
2013-09-27Fixed possible problem.irungentoo
2013-09-27Astyled the code.irungentoo
2013-09-27don't lose globally valid addresses for locally valid onesCoren[m]
2013-09-27minimalistic increase in elegance ;)Coren[m]
DHT.c: - loops over assoc4/6 slightly more elegant
2013-09-27expanded Client_data to hold two addresses (IPv4, IPv6) instead of oneCoren[m]
Compilerflag: CLIENT_ONETOONE_IP (to define in DHT.h, default unset i.e. NEW case: two addresses) Every function in DHT{_test}.c working on Client_data has been rewritten to store IPv4 addresses in assoc4, IPv6 addresses in assoc6. Loading/Storing of states defined with other compiler switch is transparently adjusting to the differences. DHT.h, DHT.c: - introduction and handling of the structure changes DHT_test.c, Messenger.c: - logging adapted to new structures util.h: - LOGGING isn't undefined per default anymore
2013-09-25Fixed bug where hole punching was attempted even though theirungentoo
clients were connected. Increased the number of ports tried per interval of time. Also astyled the files.
2013-09-24Merge pull request #596 from FullName/ping.moveandcleanirungentoo
moved stuff that belongs into ping.[ch] there
2013-09-22Fix bug.stal
This makes it build on OS X again...
2013-09-21moved stuff that belongs into ping.[ch] thereCoren[m]
DHT.*, ping.*: - moved stuff from struct DHT into struct PING: toping, last_toping - moved functions add_toping(), do_toping() - made id_closest() publicly accessible - send_ping_request(): killed (Net_Crypto *c) parameter in favor of copying it into (PING *) on new_ping() group_chats.c: - killed local 1:1 copy in favor of DHT.c::id_closest()
2013-09-21honor the claim of sort_list(), that the result is in anti-intuitive order, ↵Coren[m]
and treat element zero as the furthest
2013-09-21Merge branch 'master' of https://github.com/irungentoo/ProjectTox-Core.git ↵Coren[m]
into ipv6.yield50%toipv4
2013-09-21reserving 50%+ for ipv4, take 2Coren[m]
DHT.c: - we have to actually count the number of addresses in the field, because sort_list() will move the stuff around - improved replace_good() substantially by throwing away the "furthest" client_id, not the one just a bit worse than the new one (but better than all the later ones in the field!)
2013-09-19reserve lower half of client lists for ipv4 for nowCoren[m]
also rename client_in_list() to client_or_ip_port_in_list(), it also checks for an identical ip/port and replaces the client_id, recycling the entry DHT.c: - rename client_in_list() to client_or_ip_port_in_list() - replace_bad(), replace_good(): if IPv6, only insert into the upper half of the given list - addto_lists(): convert ipv4-in-ipv6 mapped to ipv4
2013-09-17astyled everything.irungentoo
2013-09-17Tests of state loading/saving lead to two fixes for DHT.c and util.cCoren[m]
util.c: - fix in empty section at the end of the state, showed as bug when having an empty name DHT.c: - fix in saving less data than originally announced, showed as bug when not having reached any clients ever (no clients or only with timestamp of zero)
2013-09-16Toxcore should never print anything when built normally.irungentoo

2013-09-15Fixed portablity problems.irungentoo
struct in6_addr member names can differ per platform.
