Moritz 'Morty' Strübe	b1dbc2047e	Add mesh_ready() to mesh ... mesh_ready checkes whether a packet is queued. This allows to avoid packet loss at application level.	2013-03-13 09:44:38 +01:00
Robert Quattlebaum	c0a693672c	core/net: Added support for "bridge mode". ... "Bridge mode" allows devices to more easily send 802.15.4 packets as if they were a different device. It also turns off any packet filtering that may be implemented at layer 2. It works by allowing `PACKETBUF_ADDR_SENDER` to be set earlier in the stack. This is useful for implementing 6LoWPAN-ethernet bridges. Enabled via setting `NETSTACK_CONF_BRIDGE_MODE` to 1. Disabled by default.	2013-03-10 14:45:15 -07:00

Robert Quattlebaum	f145c17039	core/net/resolv: IPv6 and mDNS ("Bonjour") support. Major refactor. ... This patch updates the DNS resolver to support IPv6 and introduces an improved API for looking up DNS entries. This patch also adds optional support for mDNS lookups and responses to the DNS resolver. Here is a quick summary of the changes: * Added support for IPv6 lookups. * DNS queries now honor record expiration. * Added support for mDNS, compatible with "Bonjour". * Implemented a new lookup api, `resolv_lookup2()`, which provides more information about the state of the record(error, expired, looking-up, etc.). About mDNS/Bonjour Support -------------------------- This patch adds basic support for mDNS/Bonjour, which allows you to refer to the name of a device instead of its IP address. This is incredibly convenient for IPv6 addresses because they tend to be very long and difficult to remember. It is especially important for link-local IPv6 addresses, since not all programs support the '%' notation for indicating a network interface (required on systems with more than one network interface to disambiguate). In other words, instead of typing in this: * `http://[fe80::58dc:d7ed:a644:628f%en1]/` You can type this instead: * `http://contiki.local/` Huge improvement, no? The convenience extends beyond that: this mechanism can be used for nodes to talk to each other based on their human-readable names instead of their IPv6 addresses. So instead of a switch on `aaaa::58dc:d7ed:a644:628f` triggering an actuator on `aaaa::ed26:19c1:4bd2:f95b`, `light-switch.local` can trigger the actuator on `living-room-lights.local`. What you need to do to be able to look up `.local` names on your workstation depends on a few factors: * Your machine needs to be able to send and receive multicast packets to and from the LoWPAN. You can do this easily with the Jackdaw firmware on an RZUSBStick. If you have a border router, you will need it to bridge the mDNS multicast packets across the border. * If you are using a Mac, you win. All Apple devices support mDNS lookups. * If you are using Windows, you can install Apple's Bonjour for Windows package. (This may be already installed on your machine if you have installed iTunes) After you install this you can easily do `.local` lookups. * If you are using a Unix machine, you can install Avahi. The default hostname is set to `contiki.local.`. You can change the hostname programmatically by calling `resolv_set_hostname()`. You can change the default hostname by changing `CONTIKI_CONF_DEFAULT_HOSTNAME`. You may disable mDNS support by setting `RESOLV_CONF_SUPPORTS_MDNS` to `0`. --------------------------------- core/net/resolv: `resolv_lookup2()` -> `resolv_lookup()` Note that this patch should fix several `resolv_lookup()` bugs that already existed. There were many cases where `resolv_lookup()` was being called and the IP address ignored, but later code assumed that the IP address had been fetched... ANYWAY, those should be fixed now. --------------------------------- examples/udp-ipv6: Updated client to use MDNS to lookup the server. Also updated the Cooja regression test simulation.	2013-03-10 11:40:08 -07:00

Oliver Schmidt	1eda821a75	Fixed severe bug in PSOCK_READTO (?) ... Either I found and fixed a severe bug in PSOCK_READTO() or I misunderstood something completely. To me PSOCK_READTO() is supposed to return if either the supplied character was read or if the user supplied buffer is exhausted - sor far so good. However if the latter occurs up to now PSOCK_READTO() was continuing to process characters already read from the network (aka present in the uIP buffer) in order to check if the supplied character was found there and adjust the return value accordingly. But this means that the character processed this way were lost forever for the caller as the next call to PSOCK_READTO() would continue to read past the characters processed this way. Therefore I removed that character processing altogether. So now if the user supplied buffer is exhausted before the supplied character is found the next call to PSOCK_READTO() starts exactly where previous call left off.	2013-02-10 15:41:34 +01:00
Oliver Schmidt	29391ef9ae	Removed uiplib_ip6addrconv() from IPv4 builds. ... While it may very well be beneficial to have explict uiplib_ip4addrconv() and uiplib_ip6addrconv() available for IPv6 builds I'm having a hard time to see the point in uiplib_ip6addrconv() for IPv4 builds. Unrelated to the above the dispatching of uiplib_ipaddrconv() to either uiplib_ip4addrconv() or uiplib_ip6addrconv() can be accomplished by the C preprocessor only thus avoiding the size/speed overhead of an additional callframe.	2013-02-03 23:04:41 +01:00

Robert Quattlebaum	5afcbf6fff	Makefiles: Allow setting UIP_CONF_IPV6=0 to work as expected. ... Setting UIP_CONF_IPV6 to zero from the make build command line is something that seems like it should ensure that IPv6 is disabled, but in fact it actually *enables* IPv6. This seems counter intuitive, so this patch changes the behavior of the makefiles to handle this case properly.	2013-01-14 22:03:42 -08:00
George Oikonomou	68f59113d6	Fix a route lifetime bug ...

Adam Dunkels	a9cab81d4e	Added macros that allow handling IPv4 addresses even when uIP is configured to be an IPv6 stack	2012-11-27 23:04:33 +01:00
Adam Dunkels	afe13b22bc	Rewrote the uIP IPv6 route handling code. Instead of being nested deeply inside the uip-ds6.c file, the route management code is now in a separate file, uip-ds6-route.c. This file presents a lib/list.h API for the routes, which makes the route list much easier to use. Additionally, the uip-ds6-route.c file adds a callback API that invokes a callback when routes are added and removed.	2012-11-27 23:04:33 +01:00

Adam Dunkels	cb7842bd16	Added support for encryption and decryption of the packetbuf if macros ... NETSTACK_ENCRYPT and NETSTACK_DECRYPT are defined. Those are intended to be called as functions NETSTACK_ENCRYPT() and NETSTACK_DECRYPT() to encrypt and decrypt the packetbuf, respectively. If needed, an initialization function by the name NETSTACK_ENCRYPTION_INIT() can also be defined.	2012-11-25 12:05:00 +01:00
Adam Dunkels	0cd2f48d6e	Added NULL pointer guards	2012-11-22 11:55:01 +01:00
Adam Dunkels	d51d3f6b3e	Remove conditionals around RPL extension header #defines and typedefs. With the conditional, it wasn't possible to compile the rpl-ext-header.c file. Since #defines and typedefs and 'free' at runtime, we gain nothing by having them conditional.	2012-11-21 20:11:22 +01:00

Adam Dunkels	ec8c7e9be0	Cleanup of the node-id.h files. The node-id.h file contains ... declarations of functions for setting and getting a node ID number, a functionality that exists on many platforms. Since this functionality was not considered part of the Contiki core, each platform defined its own node-id.h file. This commit attempts to clean this up by collecting the node-id.h into a core/sys/node-id.h file that replaces the old node-id.h files from the platform directories.	2012-11-20 19:59:46 +01:00

Adam Dunkels	2a96835c05	Don't remove all parents that have a worse rank than an incoming DIO: we may inadvertently remove our preferred parent. Instead, remove parents with a rank that is worse than our preferred parent. If we are lucky, this will give us enough space for the new parent.	2011-02-13 14:16:15 +01:00
Adam Dunkels	f1ac94e415	Slight code complexity reduction	2011-02-13 14:14:49 +01:00

Adam Dunkels	ba6bf7dd6b	Rewrote the parent selection to favour parents with a low ETX and a good rank. The old parent selection would always favour parents with a lower rank, regardless of their ETX, which in some cases lead to suboptimal parent selections. Also, the old code was buggy in that it would always pick the worst parent (the one with the highest ETX).	2011-02-11 14:17:26 +01:00

adamdunkels	09c223f549	Updated Contiki X-MAC to use hardware acks, which allows for tighter timing and results in a lower duty cycle. Hardware acks also make X-MAC more robust against packet losses, as there is a direct way for the CSMA layer to detect loss of data packets. Before, Contiki X-MAC only detected loss of strobes.	2011-01-25 14:31:09 +00:00
adamdunkels	d51e99a3dd	Updated streaming mode to use only about 20% radio. Made guard time more conservative due to problem report by Ricklef Wohlers.	2011-01-25 14:29:46 +00:00

adamdunkels	26e3b6fdc0	Bugfix by Simon Duquennoy: don't transmit packet until previous packet has been sent by the RDC layer.	2011-01-13 19:06:22 +00:00
adamdunkels	81d23a3a36	Minor bugfixes pertaining to queue handling: if a packet was explicitly dropped, the packet would later be acknowledged despite it never being received; added a limit on how many queue entries that can be used for packets that are being forwarded, to allow for originated packets even if the forwarding queue is filled.	2011-01-10 15:10:43 +00:00
adamdunkels	70f9f075a0	Safeguard against NULL arguments	2011-01-10 15:08:52 +00:00
adamdunkels	148bd60fe1	Bugfix: the defensive retransmission timer setting must be made before the packet is transmitted, otherwise the retransmission timer will always be for the defensive retransmit	2011-01-09 23:49:27 +00:00
adamdunkels	50a3e6ea23	Increased the max ETX to allow for longer paths even with the initial conservative ETX estimate; made collect use announcements by default	2011-01-09 23:48:33 +00:00
adamdunkels	acf45ec648	Bugfix: memory wasn't freed when a neighbor was dropped from the list. Also increase the max age to 180 minutes to allow for regular beacons to refresh the neighbor before it is dropped.	2011-01-09 21:20:05 +00:00
adamdunkels	90dc0ceebf	Replaced default link estimator with an exponential weighted moving average, which reduces memory consumption per neighbor.	2011-01-09 21:14:22 +00:00
adamdunkels	4e91d9303e	Added safeguard timer if the MAC layer would fail to call back after transmission.	2011-01-09 21:13:20 +00:00

nvt-se	8f76c82433	Improved DAO management.	2010-12-17 15:24:25 +00:00
adamdunkels	4914739e5d	Revived the timesynch module, which has been switched off since the introduction of the new radio API after Contiki 2.4. The new code uses explicit timestamp messages instead of piggybacking timestamps on every transmission. It is also significantly better in terms of exactness.	2010-12-16 22:47:38 +00:00
adamdunkels	10fb99a89d	Reduced the value of the max depth, so that a count-to-infinity loop will not count too long before hitting the maximum value. This is important when a network loses its sink, so that packets are not forwarded around the network for ever.	2010-12-16 22:46:34 +00:00
adamdunkels	19e930e6f2	Changed the behaviour of retransmissions to work better with the in-order CSMA code. The retransmission timer is now set when the packet is known to be sent by the MAC layer.	2010-12-16 22:45:15 +00:00
adamdunkels	4a89cc9db3	Rework of the new CSMA in-order code that fixes a number of smalllish bugs in the in-order code.	2010-12-16 22:44:02 +00:00
adamdunkels	79f2c25dae	Rework of the phase-lock optimization mechanism. There were several bugs in the existing code, such as the phase-lock would lose synchronization when a packet was lost.	2010-12-16 22:43:07 +00:00
adamdunkels	01c28ab502	Added explicit timestamp packet type, for the revived timesynch support	2010-12-16 22:41:43 +00:00

dak664	a026c94467	Fix compiler warnings	2010-12-14 22:45:22 +00:00
dak664	0a4a0ffb32	Add SICSLOWPAN_CONF_ACK_ALL for hardware autoack testing	2010-12-14 22:18:20 +00:00
dak664	240d478c1f	Allow platform to specify COLLECT_CONF_BROADCAST_ANNOUNCEMENT_MAX_TIME	2010-12-14 22:14:33 +00:00
adamdunkels	952dfc9384	Rework of the CSMA layer: instead of using one timer per packet, the module now uses one central timer and a queue of outgoing packets. This helps to keep packets in order, which is extremely useful for TCP transfers, and reduces the amount of congestion since consecutive packets now are spaced in time if there is a collision. Based on the observations and ideas of Simon Duquennoy.	2010-12-14 07:57:14 +00:00
dak664	0e60c99e80	Add defines to set stateful address prefixes.	2010-12-13 23:27:40 +00:00

adamdunkels	c19a967973	Bugfix: with the recent bugfixes, it was no longer possible to turn duty cycling back on after it had been turned off	2010-12-07 23:12:54 +00:00
joxe	e1fbb9bba0	changed neighbor state callbacks to occur only at add and remove	2010-12-07 10:36:03 +00:00
nvt-se	b2a28e6fc3	Fixed error reported by Pieter Agten. The reachable time is specified in milliseconds, and must thus be divided by 1000.	2010-12-06 09:48:48 +00:00
adamdunkels	4c9793f428	Let ContikiMAC remember the state that the radio should have when duty cycling is turned off. This fixes a bug in which the radio was turned on after sending, even when NETSTACK_RDC.off(0) was enabled.	2010-12-06 09:08:22 +00:00

adamdunkels	2f66db3ded	Added a debug mode that keeps track of where individual queuebufs are allocated, which is useful when debugging queuebuf leakage problems.	2010-11-25 08:43:59 +00:00
nifi	3bd78893e5	Renamed nullrdc to nullrdc-noframer and nullrdc-framer to nullrdc. ... nullrdc (previously nullrdc-framer) is now a RDC implementation that does not do any radio duty cycling but supports link layer addresses and frame format via framer (for example 802.15.4). nullrdc can now be used in the same way as contikimac, xmac, etc. nullrdc-noframer (previously nullrdc) is a null RDC implementation that does not do any radio duty cycling, does not add any header of its own to the packets, and does not support link layer addresses.	2010-11-23 18:11:00 +00:00
dak664	62d7832fff	Fix compiler warning and possible bug	2010-11-13 16:37:42 +00:00

joxe	9a1f902881	made rank use full resolution when using OF-ETX	2010-10-28 20:39:06 +00:00
adamdunkels	f5031861ac	When IPv6 ND kicks in, the packet that caused the ND can either be dropped or saved in a buffer to be send when the NS reply returns. This commit reimplements the buffer management to avoid having one buffer per neighbor, but instead use a buffer pool from which buffers can be allocated for different neighbors.	2010-10-28 15:42:56 +00:00
adamdunkels	677575fc8c	Rewrote proactive link estimator to be invoked randomly instead of triggered by an empty queue; this makes network bootups because nodes are not synchronized	2010-10-28 15:36:02 +00:00
joxe	932fed8cc7	improved ETX calculation	2010-10-28 08:54:54 +00:00
nifi	25ceab07d2	Update annotation when removing preferred parent.	2010-10-27 12:27:57 +00:00
nifi	d2a3f1f257	We found that the preferred parent should be reset in the rpl_remove_parent function.	2010-10-27 12:20:35 +00:00
nvt-se	d528039f9a	Created a separate function for local repair. Added a statistics structure. Improved the control of malformed packets.	2010-10-27 00:46:40 +00:00
nvt-se	c2c0505402	Increased alpha to 85 in order to get slower changes in the ETX. Put back the start guess to 3.	2010-10-27 00:45:24 +00:00

adamdunkels	77ecfb0366	Rewrote parts of the retransmission logic so that collect is robust against the situation where the MAC layer will fail to callback after a packet has been transmitted.	2010-10-24 21:08:19 +00:00
adamdunkels	8fa7bf6c31	Always restore the queuebuf to the packetbuf before calling the upper layers. Reduce the waiting time between successive MAC layer retransmissions.	2010-10-24 21:07:00 +00:00

adamdunkels	9cb830ed37	Timing bugfix in the waiting period between channel samples to check if the coast is clear before sending a packet.	2010-10-20 22:25:24 +00:00
adamdunkels	3ffcff0656	Added mechanisms for explicit de-synchronization of synchronized neighbors. Added link-layer ACKs. Fixed bugs with MAC-layer interaction. Now seems to work somewhat (didn't work at all before, in some cases), but there are still problems with packet loss.	2010-10-20 15:23:43 +00:00
adamdunkels	5585d72c86	A simple but substantial change: uIP used the htons()/HTONS() macro ... functions for converting between host and network byte order. These names are the de facto standard names for this functionality because of the original BSD TCP/IP implementation. But they cause problems for uIP/Contiki: some platforms define these names themselves (Mac OS, most notably), causing compilation problems for Contiki on those platforms. This commit changes all htons to uip_htons instead. Same goes for htonl, ntohs, and ntohl. All-caps versions as well.	2010-10-19 18:29:03 +00:00

adamdunkels	ec716ea62d	Do not reduce transmission interval, unless explicitly told so with the bump flag	2010-10-11 23:43:01 +00:00
adamdunkels	37adf130b4	Rewrite of the congestion logic. A node now report it being congested ... when half the transmission queue is full. When a neighbor is heard to be congested, the rtmetric of that node is inflated to avoid sending more traffic in its direction. Fixed problems with beacon intervals: intervals are now not reduced when a path gets significantly worse, only when they get better.	2010-10-11 23:42:01 +00:00
adamdunkels	d821ba5e22	Added a lifetime for link estimates: if they are too old, they are ... reset so that a new probing period can produce more up-to-date estimates. Added a congestion mechanism whereby a neighbor can be marked as being congested for a period of time, during which the ETX for the neighbor will be artificially inflated.	2010-10-11 23:38:46 +00:00
adamdunkels	5eb4a0fe8d	Rewrote the initial link estimate logic: link estimates are now ... computed only over the actual samples, not over the entire buffer. Also, the initial link estimate is much more conservative now (16 transmissions) to favor links that have been probed, and which therefore are likely to have better ETXs.	2010-10-11 23:34:02 +00:00
adamdunkels	0cabe483c3	Don't call sink recv function for zero-size packets, since these most likely are link estimate probes or keepalive packets. Explicitly set eseqno to zero when opening a new connection.	2010-10-07 15:52:28 +00:00
adamdunkels	ad35c54473	Bugfix: when a node's rtmetric was lower than SIGNIFICANT_RTMETRIC_PARENT_CHANGE, its beacon timers would always be bumped to its lowest value	2010-10-05 20:06:47 +00:00
adamdunkels	52e9a6f1fb	Turned the DRAW_TREE debug flag off by default	2010-10-04 22:36:47 +00:00
adamdunkels	65d640ac53	Several bugfixes to the proactive link estimate maintenance code, which is now enabled by default. Simplified DRAW_TREE code for drawing routing graph in Cooja. Added routing metric penalty to parents that are congested or that drop packets.	2010-10-04 20:27:50 +00:00
adamdunkels	212e73faa6	Removed old netsim code. Added a function for obtaining the packet attributes of a queuebuf packet.	2010-10-04 20:26:01 +00:00

adamdunkels	ceebd7020a	Bugfix: the return value sometimes was wrong when a collision was detected.	2010-10-03 20:39:24 +00:00
adamdunkels	ae88ed04f1	Moved the definition of the channel check rate used by the radio duty ... cycling layer. This definition was previously held in net/mac/mac.h, with the name MAC_CONF_CHANNEL_CHECK_RATE. But since the rate is used by the radio duty cycling layer, it makes more sense to change its name to reflect this. Also, the configuration option should be tied to the netstack configuration instead. So the new configuration option is called NETSTACK_CONF_RDC_CHANNEL_CHECK_RATE.	2010-10-03 20:37:32 +00:00
adamdunkels	40583fe112	Removed the polite announcement code, since it was not used, and enabled the broadcast announcement code by default. Increased the default intervals for broadcast announcements.	2010-10-03 20:10:22 +00:00
adamdunkels	605392522f	Bugfixes and improvements: rtmetrics are now 16-bit clean. Added experimental feature that proactively probes neighbors that have not yet been tried out, in order to get an initial ETX for them.	2010-10-03 20:08:44 +00:00

adamdunkels	eed22a6f3c	A number of changes to the collect code: ... * Added an optional "keep alive" mechanism whereby an idle network is periodically probed by dummy packets to maintain a recent quality metric when there is no traffic. * Bugfix in when new routing metrics should be advertised * Rewrote the ACK logic so that a queuebuf is not allocated for each ack, only for those acks generated by the sink node. * Updated the wrap-around logic for sequence numbers: when a sequence number wraps, it won't go back to 0. Instead, it wraps to 128. This allows us to understand when a node has rebooted: when its seqno is < 128, it has recently rebooted.	2010-09-22 22:08:08 +00:00
adamdunkels	2cae71e89b	Added a function for obtaining the link estimate and rtmetric for a neighbor	2010-09-22 22:04:55 +00:00

adamdunkels	eb58968459	Added a timer to each phase structure that keeps track of for how long ... a particular receiver has not ACKed packets. After some time (currently 16 seconds), the sender will begin sending full strobe periods again.	2010-09-13 13:39:05 +00:00
adamdunkels	591766e663	Significant improvements to the Collect protocol: ... * Loop detection and untangling. Now uses in-band loop detection that works. * Link quality estimation. Now starts with a conservative / pessimistic estimate for new links. * Retransmissions. MAC layer and network layer retransmissions are now decoupled. * Loss handling. Deals better with losses now. * Concurrent applications. Each connection now maintains its own neighbor table with separated cost to sink estimates for each connection.	2010-09-13 13:28:14 +00:00
adamdunkels	4e0744954a	Rewrite of important parts of the Collect logic: link estimation ... calculation and parent selection. This fixes a severe bug that caused loops when packets were erroneously retransmitted due to ACK loss.	2010-09-08 19:21:45 +00:00

oliverschmidt	e5665fb968	The recent change turning uip_buf from an array to a pointer seems a quite heavyweight way to have the uip_buf alligned to a 32-bit boundary. Contiki is - still - supposed to be portable across a wide range of toolchains - therefore it i.e. intentionally doesn't use C99 features. From that perspective it seems questionable if all toolchains are able to optimize away the overhead imposed by an "unnecessary" indirection to access uip_buf - and uIP consists mostly of accesses to uip_buf. Even if the future is supposed to bring support for multiple uip_bufs which would turn the uip_buf pointer from a mere workaround to an neceesary element on can still presume that there will be targets with resources limited in a way prohibiting the use of several uip_bufs. So at least for those targets will still be a usecase for a "plain", not indirected uip_buf. ... Therefore it seems reasonable to allow to stay with the "plain" uip_buf at compile-time.	2010-05-08 07:23:55 +00:00
