* lib: Deprecate ouroboros_init and ourboros_finidimitri staessens2017-10-141-1/+1
| | | | | | | | | | | | | | This commit deprecates ouroboros_init and ouroboros_fini and adds them as a constructor or destructor, causing these function to be run automatically when a program that links to the library calls and exits main(). For this to fully work, the library had to be split so that we can avoid the irmd calling these functions (the IRMd has to create the shm structures on which these calls depend). The library is split in 3 parts: libouroboros-dev, libouroboros-irm and libouroboros-common. The latter is linked to the other two so that including libouroboros-dev or libouroboros-irm will also link libouroboros-common.
* ipcpd: Fix unreachable code in shim-eth-llcdimitri staessens2017-10-111-1/+9
| | | | | Closing the file descriptor after a while(true) loop led to clang compiler errors. This is fixed by adding a cleanup handler.
* ipcpd: Cancel threads in IPCPsdimitri staessens2017-09-211-28/+21
| | | | | | This reduces CPU consumption and shutdown times. Invalidates #43
* ipcpd, lib: Add flow down eventsSander Vrijders2017-09-191-30/+177
| | | | | | | | This adds the flow down event to Ouroboros. In the shim-eth-llc, a netlink socket is opened which listens to device up/down events. For each event the flow is then adjusted with fccntl to notify the user the flow is down or back up again. In the normal IPCP an event is thrown if a write reports that the flow is down.
* ipcpd: shim-eth-llc: Fix FreeBSD compilationSander Vrijders2017-09-111-15/+17
| | | | | This fixes the compilation on FreeBSD systems. A define was missing. It also fixes some style errors.
* ipcpd: Add check if name was already registeredSander Vrijders2017-08-301-10/+1
| | | | | This adds a check in the shims if a name was already registered, since it should not return an error.

| * shim-eth-llc: Hide directory query lockingSander Vrijders2017-08-291-22/+4
| | | | | | | | | | | | | | The locking of the directory queries was happening in the shim-eth-llc, but it should be done within the shim-data functions. Fixes #30

* lib, ipcpd, irmd: Fix bugs reported by static analysisSander Vrijders2017-08-291-2/+4
| | | | This fixes several bugs as reported by the clang static analyzer.
* tools: Add tool to connect IPCP componentsdimitri staessens2017-08-281-0/+2
| | | | | | | | | | | | This enables user-written tools to instruct IPCPs to establish and tear down connections (a.k.a. adjacencies) between its internal components (Management and Data Transfer). For more info, do "irm ipcp connect" or "irm ipcp disconnect" on the command line. This commit exposes a deletion bug in the RIB where FSO's fail to unpack/parse. This will be fixed when the RIB is deprecated.
* ipcpd: shim-eth-llc: Fix building LLC shimSander Vrijders2017-08-231-2/+2
| | | | | | | The LLC shim was not being built even though it should be build. This is due to CMake behaviour that when you set a var in the parent scope, it is not set in the local scope. It also adds back THIS_TYPE to the shim-eth-llc.
* build: Revise the build systemdimitri staessens2017-08-211-31/+53
| | | | | | | | | | This revises the build system to have configuration per system component. System settings can now be set using cmake. The standard compliance defines were removed from configuration header and are set in the sources where needed. Also some small code refactors, such as moving the data for shims out of the ipcp structure to the respective shims were performed.
* ipcpd: Support Berkeley Packet Filter in LLC shimdimitri staessens2017-08-171-125/+205
| | | | | This adds support reading Ethernet frames using the Berkeley Packet Filter (BPF). Ouroboros now fully runs on OS X Sierra.

* ipcpd: Fix pthread_cond_timedwait deadlinesdimitri staessens2017-08-031-4/+14
| | | | | | This fixes pthread_condtimedwaits in the flow allocator of all IPCPs that had bad deadlines set (the interval instead of the actual absolute time).
* ipcpd, lib, irmd: Hardcode shim hash algorithmsSander Vrijders2017-07-121-2/+0
| | | | | | | This will hardcode the shim hash algorithms as they don't have an enrollment phase. Fixes #44
* lib, ipcpd, irmd: Add full-fledged QoSSander Vrijders2017-06-211-1/+1
| | | | | | | This adds more Quality of Service support to Ouroboros. One part is the network specific characteristics such as bandwidth, delay, ... The other part is end-to-end QoS like reliability, window based flow control, ...

* ipcpd: Allow specifying fixed syntaxdimitri staessens2017-05-151-1/+1
| | | | | | This commits adds the functions and messages to specify a fixed protocol syntax during CACEP. It also revises the messages for specifying the DT protocol syntax from the irm tool.
* lib: Add call to reserve blocks in rdrbuffdimitri staessens2017-04-261-1/+1
| | | | | | | 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: Allow specifying the hash algorithm to usedimitri staessens2017-04-161-6/+6
| | | | Currently CRC32, MD5, and SHA3 (224, 256, 384 and 512 bit) are supported.
* ipcpd: Fix LLC shim for BSD using netmapdimitri staessens2017-04-131-7/+5
| | | | Fixes #22
* lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-131-123/+69
| | | | | | | | | 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.

* ipcpd: Add netmap support for LLC shimdimitri staessens2017-04-071-52/+124
| | | | | Adds support for netmap (https://github.com/luigirizzo/netmap) to increase the performance of packet transfer over the LLC shim.
* ipcpd: Fix race condition with concurrent allocsdimitri staessens2017-04-061-5/+38

* ipcpd: shim-eth-llc: Avoid handling mgmt frame under lockSander Vrijders2017-04-061-4/+3
| | | | | This avoids handling the mgmt frames under lock, since it may deadlock if a new mgmt frame arrives in the meantime.
* 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: Add lock for allocation requestsSander Vrijders2017-04-051-1/+5
| | | | | 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.
* ipcpd: shim-eth-llc: Remove IPCP rwlockSander Vrijders2017-04-041-73/+23
| | | | | 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.
* ipcpd: shim-eth-llc: Add thread for mgmt framesSander Vrijders2017-04-041-29/+101
| | | | | | This adds a thread to handle management frames, since otherwise a deadlock can occur by blocking SDUs until flow allocation can be handled.
* ipcpd: Fix some bad lockingdimitri staessens2017-04-031-16/+14

* Change email addresses to ugent.beSander Vrijders2017-03-031-1/+2
| | | | | | | Our mailserver was migrated from intec.ugent.be to the central ugent.be emailserver. This PR updates the header files to reflect this change as well. Some header files were also homogenized if the parameters within the functions were badly aligned.
* lib: Remove application entity nameSander Vrijders2017-02-241-12/+3
| | | | | The AE name should not be passed over the layer boundaries. If an application has more than one AE it should exchange this in CACEP.
* ipcpd: Add lock to tx_ring datadimitri staessens2017-02-131-1/+49
| | | | Also fixes another lock.
* ipcpd: Remove logging if not initialized yetSander Vrijders2017-02-101-1/+0
| | | | | | This removes the logs that would print to stdout if the IPCP fails to initialize. If the user had asked that logs would be printed to the syslog this would be unwanted behaviour.
* lib, tools, ipcpd: Fix compilation on FreeBSDdimitri staessens2017-02-091-1/+0
| | | | | | | | | | | | FreeBSD defines its own bswap64 in the <sys/endian.h> header, which is now included correctly. POSIX requires XSI or RTS extensions to be enabled for the sa_sigaction field to be visible. Linux doesn't do the check correctly, but FreeBSD does. Removes the LOG_MISSING call which was deprecated with the last revision of the logging system.
* ipcpd, lib: Report IPCP creation failuredimitri staessens2017-02-091-1/+4
| | | | | | | | The IPCP will now respond with an ipcp_create_r message when it fails, informing the IRMd. Also adds some const qualifiers in the public headers and fixes some formatting in dev.c.
* lib: Log to the logging systemdimitri staessens2017-02-081-69/+58
| | | | | | | | | | This removes the logfile and outputs log messages to the logging system. The creation of the logfiles (as well as the ap_init() call) were moved into ipcp_init() to simplify the IPCP creation and shutdown. Fixes #25 Fixes #27
* ipcpd: Refactor ipcpi structdimitri staessens2017-02-071-26/+34
| | | | | | | | | The ipcp-ops header was removed and merged into ipcp.h. The common components dif_name and ipcp_type have been moved to the main ipcp struct. After this move, ipcp_data only contained shim information, so it was renamed to shim_data. The ipcp_init() function checks the type and will only include the shim_data if the type is not an IPCP_NORMAL. All ipcps have been adapted to this change in API.
* ipcpd: Remove strdup() from ipcp main loopdimitri staessens2017-02-031-1/+8

* ipcpd: Don't strdup() the dif_name in main loopdimitri staessens2017-01-291-3/+0
|
* ipcpd: Let IPCPs bind a nameSander Vrijders2017-01-091-8/+2
| | | | | | | 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.
* ipcpd: Add boot and shutdown operationsdimitri staessens2017-01-041-5/+13
| | | | | | | These operations separe the starting and joining of the main ipcp threads into ipcp_boot() and ipcp_shutdown() operations. This allows the proper cleanup of user data and user threads after the IPCP is requested to shut down.
