Csaba Kiraly d1822b5880 collect: making some protocol parameters configurable by COLLECT_CONF_ style defines
TTL (which has a rather low default of 15), MAC level retransmissions,
overall number of retransmissions, and the header bits dedicated to these
were all fixed in the collect.h and collect.c, without a simple way to
override them.
Extracted these as COLLECT_CONF_ parameters, keeping defaults as they were
before.

Adam Dunkels 9114cd3215 Added an API for getting a callback when a ping reply is received. 2013-12-13 08:36:51 +01:00
Adam Dunkels a6a081e67d Fixed a severe error in the bugfix: the conditional was reversed. The check must be if the TCP MSS is larger than the BUFSIZE and not the other way around. 2013-12-12 22:43:28 +01:00

Adam Dunkels c0b3c87ba7 Make 0 the default link-layer header length, as far as uIP is concerned. Most currently used linke layers (specifically, 802.15.4) has adaptation layers that use separate buffers, so there is no need to reserve space in the uIP buffer. 2013-12-12 22:20:09 +01:00

Benoît Thébaudeau 4deba89f81 rdc: duplicate packets: Keep only the last sequence number for each address
According to IEEE 802.15.4e (§6.4.3.9), in order to detect duplicate received
MAC-layer frames, only the most recently received frame's sequence number needs
to be stored for each unique device address. Doing so limits the possible false
duplicate packet detections to a single sequence number. This also allows to
keep the last sequence number of more device addresses for the same value of
MAX_SEQNOS.

Benoît Thébaudeau 477a4a7178 rdc: duplicate packets: Factor out detection code
The code detecting duplicate packets in the RDC layer had been copied into most
RDC implementations. Factor it out into a new mac-sequence module in order to
have a single instance of this code.

Benoît Thébaudeau 14db3382af csma: Initialize sequence number with random value
According to IEEE 802.15.4 (§5.1.6.1, §6.4.2), the MAC sequence numbers should
be initialized to random values. This was already the case in
framer-802154.c:create(), but not in csma.c:send_packet(), sometimes causing
false detections of duplicate MAC-layer packets in other devices when a device
was restarted too quickly. This patch decreases the probability of such an
event.

Adam Dunkels faff1c2a7e Preliminary support for RPL node types. This change allows a node to be in any of three given types:
* Mesh: this is the normal case. Nodes route data on behalf of others and the node can be reached via a DAO route.
* Leaf: the node does not route data on behalf of others, but others can route data to the node (it has a RPL DAO route).
* Feather: this is a new type of node. A feather node routes data on behalf of others, but does not install DAO routes in the network. Feather nodes allow having a larger number of nodes than the RPL network can sustain in terms of routing tables.

This commit introduces the RPL node types and the feather mode, but does not add support for the leaf node type.

Adam Dunkels 61ea7fbb1c RPL DAO timers and management:
* Added a DAO lifetime timer that sends out a new DAO after half the lifetime of the DAO. This allows implementing DAO route soft state that avoids routing tables in the network keeping stale routes for ever.
* Added ways to schedule a new DAO transmission as well as cancelling an active DAO transmit timer, which makes it possible to do nodes that don't send DAOs.

Adam Dunkels b31e84649a If the 6lowpan layer is currently reassembling a packet, and a non-fragmented packet comes along, this is a sign that one of the fragments were lost (as they normally would arrive back-to-back, in sequence). So we'll grab the non-fragmented packet instead of dropping it. 2013-11-22 15:12:02 +01:00

Ari Suutari c1c64dd1cc Received UDP packet was counted twice in statistics, first in udp_input and then again in udp_found.
Fix this to use same logic as in uip.c: valid packet is counted only in udp_found.
