Implement support for PWid group wildcards. This was missing from our original RFC 4447 VPLS implementation. Now ldpd understands group wildcards as mandated by the RFC, but we still don't send them ourselves. I can't see any case in which sending a group wildcard would be useful, but nonetheless this patch provides a function called lde_send_labelwithdraw_pwid_wcard() which is ready to be used in the future anytime we feel like it might be useful.

Fix processing of Label Withdraw messages. Whenever we receive a Label Withdraw message with an optional Label TLV, we should check if this label matches the label previously received from this neighbor for this FEC. If they don't match then we shouldn't uninstall the previous label from the kernel. This fixes a misinterpretation from the "Receive Label Withdraw" algorithm described in the A.1.5 section of RFC 5036. Also, simplify the check of pending withdraws in lde_check_release() and lde_check_release_wcard().

Fix small LIB<->LFIB synchronization issue. ldpd operates only with the best routes of each IP prefix. In other words, the routes with the lowest priorities. When a route with a better priority is detected (possibly with a different nexthop), we should uninstall the labels from the "old" routes and try to install a new label for the new route (if there's one available in the LIB). In this specific case, ldpd was failing to uninstall the labels from the old routes because it wasn't keeping track of each route's priority in lde. With this missing bit of information, the parent process had no way to get the correct label to uninstall when processing a IMSG_KLABEL_DELETE message.

Make functions and variables static whenever possible. The benefits of this include: * clean up of the ldpd global namespace; * improved readability; * more hints to the compiler/linker to generate more efficient code. Whenever possible, move global static variables to a smaller scope (function). All extern variables are now declared in header files to avoid unnecessary duplication. This patch also cleans up the indentation of all function prototypes and global variables.

Rename a few constants to avoid confusion. In ldpd we have the map structure, which is used to represent a label message, and the fec structure, used to store FECs in the LIB. As of now, ldpd supports two type of FECs: * IPv4 prefix (FEC_TYPE_IPV4); * PWID (FEC_TYPE_PWID). For the label messages, the following contants were being used: * FEC_WILDCARD; * FEC_PREFIX (IPv4 or IPv6); * FEC_PWID. Since these contants have similar names to the previous ones, rename them to: * MAP_TYPE_WILDCARD; * MAP_TYPE_PREFIX; * MAP_TYPE_PWID.

VPLS signaling support. This patch introduces full support for pseudowire signaling in ldpd(8), including Control Word and Status TLV negotiation. As of now it's not possible to configure a VPWS, but the signaling is the same. In the future, when VPWS support is available in the kernel, ldpd(8) can be extended to support VPWS with only a few modifications. Limitations: * No support for FEC 129, only FEC 128 (more widely deployed); * No support for group withdraws (not widely deployed); * No support for MAC withdraws (not widely deployed). Related RFCs: * RFC 3916: Requirements for Pseudo-Wire Emulation Edge-to-Edge (PWE3) * RFC 3985: Pseudo Wire Emulation Edge-to-Edge (PWE3) Architecture * RFC 4385: Pseudowire Emulation Edge-to-Edge (PWE3) Control Word for Use over an MPLS PSN * RFC 4446: IANA Allocations for Pseudowire Edge to Edge Emulation (PWE3) * RFC 4447: Pseudowire Setup and Maintenance Using the Label Distribution Protocol (LDP) * RFC 4448: Encapsulation Methods for Transport of Ethernet over MPLS Networks * RFC 4905: Encapsulation Methods for Transport of Layer 2 Frames over MPLS Networks * RFC 4906: Transport of Layer 2 Frames Over MPLS ok claudio@

Record all fields of the received label mappings. Since we implement the Liberal Label Retention mode, we need to record all fields of the received label mappings so the messages can be processed later when there is a matching nexthop for the advertised FECs. This will be important when we implement VPLS because we need to retain information like the pseudowire's interface MTU and Group ID. ok claudio@

Rework label mapping algorithms to be more in line with the RFC.
This patch presents a thoroughly review of the label mapping
algorithms. Most of the changes are minor bug fixes in the handling of
received label messages.
Additional improvements:
* Add a few more references to the Appendix A of the RFC5036 ("LDP
Label Distribution Procedures") into the code;
* Add full multipath support;
* Send label withdraws when appropriate;
* Add label withdraw/release wildcard support.
NOTE: As a result of implementing only the "Liberal Label Retention" and
"Downstream Unsolicited" modes, we will never send a label request
("Request Never"). And that means that we can ignore the following
notification messages: "Label Request Aborted", "No Label Resources",
"No Route" and "Label Resources Available". The following algorithms
mentioned in the RFC can also be ignored: "Timeout of Deferred Label
Request", "Detect Local Label Resources Have Become Available" and
"Receive Label Abort Request".
Now, considering that we only support one combination of all modes of
operation, we can say that we have an almost complete implementation of
the protocol.

Remove incomplete support for unnecessary modes of operation. LDP has several modes of operation, it was designed in that way so it could run on legacy equipment like ATM/FR switches with very strict memory limitations. For modern hardware there's no point on using either the "Conservative Label Retention" or "Downstream On Demand" modes of operation since they save memory at cost of blackholing traffic when routing changes. Major vendors implement only the "Liberal Label Retention" and "Downstream Unsolicited" modes for non ATM/FR hardware. Let's do that too. As for using either "Independent Control" or "Ordered Control", let's stick with the first option mainly because it's easier to implement and because it doesn't really matter which control mode is used. For reference, Cisco implements only "Independent Control" and Juniper only "Ordered Control". Both modes are interoperable. The point of supporting only one combination of all modes of operation is that it will allow for the writing of a simpler code without removing useful functionality. ok claudio@

Rework kroute.c to send only the best routes to lde. This is major rework of the kroute.c code. The idea is remove complexity from the lde process by making kroute.c advertise only the lowest priority routes of each prefix. kroute.c now keeps track of all routes using three different structures: kroute_prefix, kroute_priority and kroute_node. kroute_prefix represents a prefix and contains an ordered list of priorities (kroute_priority) and for each priority there is a list of nexthops (kroute_node). Arranging the routes using these three structures allows for the writing of a simpler code, easier to understand. Whenever a route is removed, if there's another route for the same prefix, but with a lower priority, this route is immediately sent to lde. Additional fixes: * On RTM_CHANGE, remove the old route before installing the new one; * On IMSG_CTL_KROUTE_ADDR, show all nexthops for multpath routes;

Show the full LIB in the "ldpctl show lib" command. The LIB is a table where the router keeps all known MPLS labels. So, we should loop over all the received label mappings from all neighbors to show the full LIB. The lde_nbr_is_nexthop() function was introduced to verify if a lib entry is supposed to be installed in the fib (according to the fib entry's nexthop and the addresses advertised by the lib entry's nexthop). This is better than keeping track of lib<->fib entries with pointers and back pointers because it keeps the lib/fib structures independent of each other, which in turn makes the code less prone to bugs.

Store all labels in ldpd in host byte order without any additional shifting. Add the necessary ntohl() and shifts in various places and cleanup the byte order mess we had before. michele@ agrees.

Start reworking the LDE. Implement a FEC RB tree that can be used for the route table and the per neighbor request and mapping lists. The received and sent mappings are added to the per neighbor RB tree and additionally linked to the route table. This makes lookups, etc. a lot easier. While there flip the neighbor hash list over to a RB tree. OK michele@

Remove yet another ospf leftover that is not needed here. This time neighbor self and all the madness surrounding this amazing concept. LDP is not self aware so there is no need for this. OK michele@

Rework the kroute code by stealing some code from ospfd and massaging it a lot more. Main reason for this is to add priority support. Additionally add some additional NO_LABEL fixes. OK michele@

If a neighbor goes down we need to cleanup the LIB from all FEC that point via that neighbor. Fixes a use after free and an additional NULL dereference in a log_debug is fixed as well. OK michele

"ldpctl show lib" output cleanup. - Show only the remote/local labels of the prefixes currently present in fib. - Write a "-" instead of "0" when a remote label is not present (the prefix is directly connected). It avoids confusion with explicit null label. ok claudio@

Welcome ldpd, the Label Distribution Protocol daemon. Built using the imsg/three process framework, its main aim is to redistribute MPLS labels between peers. Right now it has some really basic functionalities, the basic protocol works and peers are able to exchange labels and insert them in the kernel. It still does not react to changes of topology. Not yet connected to the builds. ok claudio@ deraadt@
