| * irmd: Handle death of IPCP gracefullydimitri staessens2017-02-043-12/+30
| | | | | | | | | | | | | | If an IPCP SEGVs abruptly, the sanitizer in the IRMd would also cause a SEGV because of looping over a registry linked list inside another safe loop over the same list. A function is added to the registry to avoid this.
| * lib: Handle receiving CDAP reply before waitdimitri staessens2017-02-041-1/+9
| | | | | | | | | | | | In extreme cases, the response to a CDAP request can arrive before the AE doing the request has called cdap_request_wait. This PR handles it by waiting for the state to move away from INIT before responding.

| * lib: Fix insertion order in RIBdimitri staessens2017-02-021-8/+13
| | | | | | | | | | | | | | | | The new element must be added before the larger element (list_add_tail, since it's a circular list). Also fixes a bug and improves the locking in rib_pack (rib must be locked until the subtree is fully packed in the buffer).

| * lib: Add packing and unpacking RIBdimitri staessens2017-01-315-50/+359
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rib_pack function allows packing a subtree of the RIB for dissemination. The options PACK_HASH_ROOT and PACK_HASH_ALL will add the hashes for the root object of the packed subtree or every object to the packed message respectively. Checking of the hashes is currently only performed at the top level object, verifying the complete operation. The rib_unpack function unpacks a packed message and inserts its contents in the RIB. The option UNPACK_CREATE flags that the unpack operation is allowed to create new objects, else it will only update existing objects. More advanced options could be added in the future. The packed message structure uses Google Protocol Buffers, as defined in ro.proto. It adds tests for these functions to the rib_test.

| | | | | | | | | | | | When trying to double bootstrap, the entry name was strdup'd before the bootstrap leaking the previous name. Now it bootstraps first and sets the name after a successful bootstrap only.

| * lib: Add new version of Resource Information Basedimitri staessens2017-01-217-0/+1455
| | | | | | | | | | | | | | | | | | | | | | | | The new RIB is implemented as a tree with doubly linked nodes (parents keep a link to each child, each child keeps a link to its parent). An index is kept in a btree using CRC32 hashes of the path name in the RIB. Nodes keep an SHA3-256 hash value that is unique for the entire subtree. This allows quick checks to see if two RIB subtrees are in sync. The event system for the RIB is based on the event system for flows (fqueue), but implemented completely in dynamic memory using linked lists. An initial test is performed for the RIB. This PR does not modify existing code to use the new RIB.

| | | | | | | | | | | | | | | | Sometimes the timerwheel test could fail because of scheduler timings (an issue more apparent in Virtual Machines). When the first check fails, the test will wait for another complete round of the timerwheel. The maximum number of slots in the test is reduced to reduce the test time.

| | | | | | | | | | | | | | | | | | | | | This allows IPCPs to bind a name, so that they can announce their name to neighbors which can then allocate a flow to them. Registering of the name happens by an administrator. It also moves the irmd_api to common ground, since it is used by all IPCPs.
