* lib: Add call to reserve blocks in rdrbuffdimitri staessens2017-04-268-23/+62
| | | | | | | This adds a call ipcp_sdb_reserve to reserve memory in the rdrbuff without directly writing to a flow. The ipcp_flow_del function was renamed to ipcp_sdb_release. The functions operating on sdbs are moved to their own header.
* ipcpd: normal: Extract flow sets from componentsSander Vrijders2017-04-244-65/+58
| | | | | | The flow sets were still kept within the FA and DT components, when it makes more sense that they are kept within the SDU scheduler component.
* ipcpd: normal: Split flow manager into DT and FASander Vrijders2017-04-2111-884/+972
| | | | | | This splits the flow manager into the Data Transfer AE, which is in charge of routing SDUs, and the Flow Allocator AE, which handles flow allocations.

| * ipcpd: Build complete graph with gamdimitri staessens2017-04-204-21/+78
| | | | | | | | | | The complete policy will now build a complete graph. Currently a simple timer is used to check the member list periodically.

* | ipcpd: normal: Extract SDU scheduling componentSander Vrijders2017-04-194-127/+236
|/ | | | | | This extracts the SDU scheduling component out of the Flow Manager since the functionality was duplicated. For both the N-1 and N+1 flow sets an SDU scheduling component is now created.
* lib: Fix compilation error in hash.cSander Vrijders2017-04-191-0/+2
| | | | | If compiled as release build, an error would be generated as the control reaches the end of a non-void function.

| | | | | | | | Currently CRC32, MD5, and SHA3 (224, 256, 384 and 512 bit) are supported.

| * lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-1346-1145/+934
| | | | | | | | | | | | | | | | | | All information passed over the IRMd/IPCP boundary for using IPC services (flow allocation, registration) is now hashed. This effectively fixes the shared namespace between DIFs and the IRMDs. This PR also fixes some API issues (adding const identifiers), shuffles the include headers a bit and some small bugs.
* | build: Add STATUS to message statementsSander Vrijders2017-04-122-6/+6
| | | | | | | | | | | | This adds the STATUS variable to the message() call in CMakeLists.txt in places where it was missing. This ensures that the message is printed to stdout instead of stderr.

| | | | | Adds support for netmap (https://github.com/luigirizzo/netmap) to increase the performance of packet transfer over the LLC shim.

| | | | | | | | | | | | An assertion was done instead of NULL check, where the FRCT instance could legitimately be NULL, resulting in the IPCP dying when it shouldn't.

| | | | | | | | | | This avoids handling the mgmt frames under lock, since it may deadlock if a new mgmt frame arrives in the meantime.

* lib, irmd: Implement flow allocation timeoutdimitri staessens2017-04-0611-137/+243
| | | | | | Setting the timeouts on flow_alloc and flow_accept will now work. This makes some changes to the UNIX sockets used for management communication between the APs, IRMd and IPCPs.
* ipcpd: shim-eth-llc: Fix overwrite mgmt framesSander Vrijders2017-04-051-21/+42
| | | | | | This fixes the overwriting of management frames by adding a list in the shim Ethernet that keeps track of management frames instead of a single buffer.
* ipcpd: normal: Add missing else clauseSander Vrijders2017-04-052-10/+7
| | | | | A missing else clause was missing in the fast path, causing the PCI to be shrunk when it should not be. A double free has also been fixed.
* ipcpd: Add lock for allocation requestsSander Vrijders2017-04-056-103/+79
| | | | | This adds a lock to prevent a race condition between flow_req_arr and flow_alloc_resp.
* ipcpd: shim-eth-llc: Fix state check in readerSander Vrijders2017-04-051-3/+3
| | | | | The state check should be done first to avoid blocking on the recv call.

| | | | | | | | | | This removes the rwlock in the shim-eth-llc IPCP since it is already protected by a mutex.
* | ipcpd: shim-eth-llc: Remove pthread_cancelSander Vrijders2017-04-041-78/+117
| | | | | | | | | | This removes cancellation calls from the shim Ethernet. The different threads now check if the IPCP is still operational or not.
* | ipcpd: shim-eth-llc: Deprecate PACKET_RX|TX_RINGSander Vrijders2017-04-041-203/+11
| | | | | | | | | | | | This deprecates these special socket options of the raw socket since they are less efficient for regular packet I/O. They should be more performant for batch processing of SDUs.
