Adam Dunkels 19b32c54c0 Removed the old unused hc.[ch] code 2013-11-24 11:02:35 +01:00
Adam Dunkels 9819c5b5b8 Rewrote the IPv6 route management so that all routes are maintained on a list that is ordered by the time at which the route was accessed. If a new route is added to the system, the oldest route is dropped. 2013-11-22 18:00:47 +01:00

Adam Dunkels f31d6f271f Bugfix: if a SYN is received in the SYN_RCVD state we should not send a blank SYN, but a SYNACK in response. 2013-11-22 15:37:21 +01:00
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
Adam Dunkels 3788b08780 Added a way to get the RSSI of the last received packet 2013-11-22 15:10:44 +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.

Adam Dunkels bfd7e5f25b Fixed a few bugs in the route handling code. While bughunting, rewrote parts of the code to make its intention clearer. Also added a bunch of comments to make the logic of the code more evident. 2013-08-19 17:48:32 +02:00
Adam Dunkels 8dc4e46968 Check if the nexthop neighbor for a given route has disappeared. If so, we drop the route too. If we happen to be the RPL root, we also initiate a global repair as the neighbor may moved. 2013-08-19 17:48:32 +02:00
Adam Dunkels d0a939afb0 Bugfix: must multiply with ETX divisor to turn into fixed-point format. 2013-08-19 17:48:32 +02:00
Adam Dunkels 4d0ecaae02 Make sure our parent's IP address isn't NULL. 2013-08-19 17:48:32 +02:00
Adam Dunkels e5a6565137 Loop detection via DAO: if we get a DAO from a parent, that parent thinks we are its parent. We poison it and recalulate our parents. 2013-08-19 17:48:32 +02:00
Adam Dunkels 34119b7ef2 Poor man's loop reparation: reset the DIO timer and hope the neighbor learns a better route. 2013-08-19 17:48:32 +02:00
Adam Dunkels d830e9df3f Implement forwarding error handling: if a packet changes direction, we set the FWD_ERR flag. If we see the FWD_ERR flag, we drop the route that we sent it to. If we are the root node, we also initiate a global repair. 2013-08-19 17:48:31 +02:00
Adam Dunkels abb3ef9b3b Bugfix: don't set the parent if the dag is NULL 2013-08-19 17:48:31 +02:00

Simon Duquennoy c3f62b24c8 Moved ETX management from neighbor-info to rpl-of-etx. Avoids conversions between different fixed point representations, and simplifies neighbor management. Makes more clear how default-ETX and noack-ETX actually affect the rank. Removed neighbor-info and neighbor-attr. 2013-08-19 17:48:30 +02:00
Simon Duquennoy c50d10aa53 Make RPL use neighbor tables. RPL locks the neighbor used as preferred parent. 2013-08-19 17:48:30 +02:00
Simon Duquennoy 09d26f8060 Make uip-ds6-route use neighbor table. Instead of storing a global list of routing entries that contain both the next hop and the destination, we have a separate list of reachable destination for each neighbor in the global table. 2013-08-19 17:48:30 +02:00
Simon Duquennoy ec609b49eb Make DS6 neighbors use neighbor-table, and move all DS6 neighbor management from uip-ds6 to a new uip-ds6-neighbor module. 2013-08-19 17:48:30 +02:00
Simon Duquennoy 5a1d8d8006 Make phase module use neighbor-table. 2013-08-19 17:48:29 +02:00
Simon Duquennoy cfb3bbdad9 Added new neighbor-table module, a centralized place where to store all data about neighbors, indexed by link-layer address. Meant for use in other Contiki modules such as rpl, ds6, ds6-route, phase, neighbor-info. 2013-08-19 17:48:29 +02:00

Adam Dunkels f5307fc01e Bugfix: must set the SICSLOWPAM_MAX_MAC_TRANSMISSIONS attribute after clearing the buffer, otherwise it will not be used for outoing packets. 2013-08-11 14:27:21 +02:00
Adam Dunkels 0aa448f190 6lowpan fragmentation bugfix: the 6lowpan code had an unfortunate 
interaction with the behavior of the rdc layer. If the first packet of a
fragment transmission was lost, the remaining packets would get dropped
on reception. Moreover, the reception code contained a bug that
sometimes would cause fragments to be misidentified as fragments. Taken
together, these problems would result in a pathelogical network
breakdown if too many fragmented packets would occur simultaneously.

Adam Dunkels 512a339c50 Bugfix: DIOs with infinite ranks should not be ignored as they are used by RPL as a signal by nodes that have lost their routes. Instead of ignoring them, we should send out our latest information to let the node with infinite rank find their way into the network again. 2013-07-26 12:38:25 +02:00

This is a temporary fix for #183, so that things can

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.

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.

---------------------------------

Also updated the Cooja regression test simulation.

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.

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.

Setting UIP_CONF_IPV6 to zero from the make build command line is

fact it actually *enables* IPv6. This seems counter intuitive, so this
patch changes the behavior of the makefiles to handle this case
properly.

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.

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
