* | lib: Fix bad bounds calculation in frctDimitri Staessens2018-06-081-1/+1
| | | | | | | | | | | | | | | | | | Since the seqno is further ahead than the lwe (this was checked before), we can safely use seqno - lwe in unsigned arithmetic as the distance in the sequence number space.

* | ipcpd: Support data QoS cube in UDP shimSander Vrijders2018-06-081-1/+1
| | | | | | | | | | | | | | | | This will also allow flows with the data QoS cube to be allocated over the UDP shim. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* | lib: Add a data qos cubeDimitri Staessens2018-06-0811-15/+51
|/ | | | | | | | This adds a data qos cube that is reliable. Reliable qos can be selected by setting the loss parameter of the qosspec to 0. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Support raw qos in eth and udp IPCPsDimitri Staessens2018-06-082-2/+2
| | | | | | | | Flow allocation for raw was not yet supported in these IPCPS, causing enrollment to fail. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>

* lib: Fix rollover and return value in FRCTDimitri Staessens2018-06-081-4/+6
| | | | | | | | | The __frct_rcv should return -EAGAIN if there is no packet for the application, but 0 was always returned. Also fixes sequence number rollover. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Add priority for raw flowsDimitri Staessens2018-06-073-0/+8
| | | | | | | | The raw flows had no priority assigned, causing the scheduler to fail on creation. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* irmd: Retry bind for live processesDimitri Staessens2018-06-061-5/+20
| | | | | | | | | If bind was called before the process registered with the IRMd, the bind operation would fail. The IRMd will now wait for a short period until the process is registered or exits.

* tools: Add quiet option to opingDimitri Staessens2018-06-062-18/+32
| | | | | | | | | This adds a --quiet -Q option to oping so it will only print the statistics summary. Also fixes a division by 0 if duration is specified with interval 0. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* tools: Support qosspecs in opingDimitri Staessens2018-06-052-17/+39
| | | | | | | | The oping tool can now select a qos spec to use. Allowed specs are predefined an chosen using "raw", "best", "video" or "voice". Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* lib: Define default qosspecs in qos sourcesDimitri Staessens2018-06-053-32/+38
| | | | | | | | | This moves the definition of the predefined qosspecs to qos.h and qos.c. This allows applications to select them using qos_best_effort etc. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* tools: Allow specifying duration for opingDimitri Staessens2018-06-051-6/+39
| | | | | | | | | This adds a -d, --duration option to oping. Now all durations can be specified in milliseconds (ms, default), seconds (s), minutes (m), hours (h), or days(d). Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* tools: Add out-of-order statistics to opingDimitri Staessens2018-06-052-3/+16
| | | | | | | | | This adds out-of-order statistics to the oping tool. A packet is considered out-of-order if its sequence number is lower than the highest sequence number already received.

* lib: Add a QOS_RAW QoS cubeDimitri Staessens2018-06-054-15/+37
| | | | | | | | | This adds a QoS cube that allows sending packets directly over a raw flow, without an FRCT state machine. Flow allocation with a NULL qosspec will now default to such raw flows. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* lib: Simplify delta-t logicDimitri Staessens2018-06-053-58/+56
| | | | | | | | | | This revises the delta-t implementation to align with Watson's timer specifications. FRCT will never deliver out-of-order packets. A raw flow (without delta-t state machine) will be able to provide such a service.

* tools: Add timestamp option to opingSander Vrijders2018-06-012-6/+22
| | | | | | | | | This adds a timestamp option to oping, similar to the one in regular ping and rinaperf, so that we can more easily correlate time and latency. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* tools: Fix bad wildcard match in irm toolSander Vrijders2018-06-011-4/+2
| | | | | | | | The pattern was matched to the string instead of the string to the pattern, which means it only worked if it was a perfect match. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* lib: Mark flows as down on ipcp_flow_fini()Dimitri Staessens2018-05-301-34/+35
| | | | | | | | | | The flow_fini() function was marking flows as wronly (so rdonly for the application) when the flow was deallocated. With the recent addition of the flowdown state, we can now mark them as down. Also fixes some bounds checks and alignment.

* build: Fix running make check standaloneSander Vrijders2018-05-301-2/+2
| | | | | | | | | In the current build an error would happen if a user simply runs make check after running cmake, since the kademlia protocol buffer file was not generated yet. This simply regenerates the file for the test. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd: Include string for memset in graph.c0.11.8Dimitri Staessens2018-05-292-1/+2
| | | | | | | | The memset function was used without including <string.h>, which some compilers complain about. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* build: Update default values0.11.7Sander Vrijders2018-05-295-5/+5
| | | | | | | | | | | This sets updated default values for the default build. A higher connect timeout until we have asynchronous local IPC. Disabled SWIG since the lastest gcc reports an error. IPCP flow stats enabled by default since their impact on the performance is very limited. Waiting for the directory to enroll before returning to increase stability.

* ipcpd: Avoid false positive use-after-free in DHTDimitri Staessens2018-05-281-0/+1
| | | | | | | | | The static analyzer misses the linked list logic. An assertion is added that indicates that the pointer was changed indirectly by the previous element. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* build: Check for variable length arraysDimitri Staessens2018-05-283-24/+58
| | | | | | | | | | The clang and gcc compilers don't complain about variable length arrays using the -c89 flag unless the flag -Wvla or -Wpedantic is set. This also fixes a memleak and two false positive uninitialized variable warnings reported by the clang static analyzer in graph.c. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Use eid in fa protocol instead of fdDimitri Staessens2018-05-271-14/+14
| | | | | | | | | The flow allocator protocol used fd in the message exchange since eids were directly mapped to fds. It's better to name them eid in the protocol to avoid confusion.

* ipcpd: Fix memleak in DHTDimitri Staessens2018-05-271-9/+5
| | | | | | | | | | This fixes a memleak for the info struct when join thread creation is not needed. Fixes a false positive warning when running the clang static analyzer. Removes a use-after-free warning that is not valid since 0.11.4. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* lib: Fix potential memleak in rdrbuffDimitri Staessens2018-05-271-2/+4
| | | | | | | | The rdrb struct should be freed when destroying the rdrbuff, even when the actual shared memory is not unlinked. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Fix false positive incompatible malloc typeDimitri Staessens2018-05-271-6/+4
| | | | | | | | | A malloc was performed with a mgmt_msg type and converted to a uint8_t buffer for serialization, which triggers a false positive warning with the clang static analyzer.

* lib: Use IPCP name as RIB directoryDimitri Staessens2018-05-152-3/+3
| | | | | | | | This will change the FUSE mountpount to the name of the IPCP instead of a generic name based on its pid. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* lib: Add event types to fqueueDimitri Staessens2018-05-145-56/+108
| | | | | | | | | | | The event type of the current event in the fqueue can now be requested using the fqueue_type() command. Currently events for packets (FLOW_PKT), flows (FLOW_UP, FLOW_DOWN) and allocation (FLOW_ALLOC, FLOW_DEALLOC) are specified. The implementation only tracks FLOW_PKT at this point.

* ipcpd: Fix check build for DHT0.11.6Dimitri Staessens2018-05-082-1/+5
| | | | | | | | The DHT test failed on the use of IPCP-specific calls. These calls are now guarded by the correct defition checks. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Include ipcp-dev header in DHT0.11.5Dimitri Staessens2018-05-082-2/+2
| | | | | | | | The DHT called ipcp_sdb_release without including ipcp-dev, causing compiler errors on some machines. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Fix setting MTU for eth-llcDimitri Staessens2018-05-081-3/+12
| | | | | | | | The MTU was not correctly set for the eth-llc ipcp. This also fixes a missing definition of ETH_MAX_MTU, which was introduced in kernel v4.10. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Fix parameter in debug logDimitri Staessens2018-05-081-2/+2
| | | | | | | | The cpu was a size_t but printed as an unsigned long, giving compilation errors on 32 bit machines. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* tools: Disable partial reads in opingDimitri Staessens2018-05-072-3/+6
| | | | | | | | | The oping tool was using a 1500 byte buffer, but didn't account for partial reads when sending 1500 byte packets. This disables the partial reads. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Use correct MTU for eth-dixDimitri Staessens2018-05-071-4/+24
| | | | | | | | The eth-dix IPCP was using a hardcoded MTU of 1500 bytes, but could support higher MTUs. Now jumbo frames are supported. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* irmd: Fix use-after-free in mainloopDimitri Staessens2018-05-071-75/+50
| | | | | | | | | | The ret_msg struct was free'd but its result could be accessed after a failed write. Fixed by storing the results of the commands in a temporary variable and accessing this upon write failure. Also simplifies some other code.

* ipcpd: Fix bad memory handling in LFA policySander Vrijders2018-05-042-7/+8
| | | | | | | | | | | | | The Loop-Free Alternates policy had bad memory management in two places. In the calculation of the LFAs a table was freed in the first iteration of a loop, whereas it was still needed in the other iterations. It is now freed outside of the loop. In the alternate PFF the address structs were not freed upon shutdown, this has been added as well. It also fixes some bad initialization in the LFA calculation function.

* ipcpd: Limit number of returned query addresses0.11.4Dimitri Staessens2018-05-032-13/+19
| | | | | | | | | The query returned all addresses where a name was registered, causing some scaling problems. Now it will return at most DHT_RETR_ADDR, which is currently set at 1 (anycast).

* ipcpd: Allow wait for dir enrollment on dt connDimitri Staessens2018-05-037-2/+24
| | | | | | | | | This adds the option to wait for the directory (DHT) to enroll on creating a new data transfer connection. This makes scripting network bootstraps more stable. The default setting is OFF. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Recalculate PFF upon adding new neighborSander Vrijders2018-05-031-31/+42
| | | | | | | | | | This recalculates the PFF upon adding a new neighbor, so that the network reconverges faster. It is safe to do so since it is only done by the two IPCPs that established the new flow. The PFF is also recalculated every 4 seconds. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd: Prevent parallel DHT enrollment threadsDimitri Staessens2018-05-031-22/+24
| | | | | | | | | This will prevent quick calls to ipcp conn for dt flows to create multiple join threads in parallel, instead the subsequent calls will wait for the pending join to finish.

* lib: Make UNIX socket buffer size configurable0.11.3Sander Vrijders2018-05-037-14/+26
| | | | | | | | | | This makes the buffer size used by the UNIX sockets configurable. In case of a lot of IPCPs in the system it might become too small with the default value, resulting in irm command failures. The user can now easily configure it with an adequate value.

* ipcpd: Don't do lookup with new DT when runningDimitri Staessens2018-05-031-4/+8
| | | | | | | | | | The DHT performed a lookup upon a new DT connection when it was running for efficiency reasons. This lookup somehow cause SEGV under stress (rapid bootstrapping of networks). This will be solved with a full revision of the DHT implementation. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
