* 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. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* irmd: Fix comparison of uninitialized valueDimitri Staessens2018-05-271-0/+1

* tools: Fix memleaks as reported by cppcheckSander Vrijders2018-05-252-2/+6
| | | | | | | This fixes two memleaks which were reported by cppcheck. Signed-off-by: Sander Vrijders <[email protected]> Signed-off-by: Dimitri Staessens <[email protected]>
* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Add event types to fqueueDimitri Staessens2018-05-142-37/+53
| | | | | | | | | | | 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 Staessens2018-05-081-0/+4
| | | | | | | | 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Include ipcp-dev header in DHT0.11.5Dimitri Staessens2018-05-081-1/+1
| | | | | | | | The DHT called ipcp_sdb_release without including ipcp-dev, causing compiler errors on some machines. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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 Staessens2018-05-031-12/+18
| | | | | | | | | 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). Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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.

* 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. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Make UNIX socket buffer size configurable0.11.3Sander Vrijders2018-05-034-10/+17
| | | | | | | | | | 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Cleanup pending DHT commands on shutdownDimitri Staessens2018-05-031-0/+7
| | | | | | | The list of commands was not cleaned up on shutdown. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Remove cookie from DHT lookup at updateDimitri Staessens2018-05-031-1/+4
| | | | | | | | | | The lookup struct uses the cookies to track pending request messages, but they were not removed when a response is processed. Upon reuse of a cookie for the next message, it could update the wrong lookup. This removes the cookie for a lookup when it is looked for.

* ipcpd: Shut down DHT gracefully during enrollmentDimitri Staessens2018-05-031-0/+10
| | | | | | | | | The DHT has a thread that continued to run during shutdown. The shutdown state is now checked for. It will not try to send messages at shutdown. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Create notifier before connmgrDimitri Staessens2018-04-261-9/+9
| | | | | | | | The connmgr requires the notifier, but the notifier was created after and destroyed before the connmgr. This is now fixed. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Shut rx buffer down before cleanup and exitDimitri Staessens2018-04-261-0/+1
| | | | | | | | | | If a program exits, it cleans its read buffer. However, another process could still write a packet in that buffer, which would cause the IPCP or IRMd to run into an assertion failure on shutdown. Setting the rbuff to ACL_FLOWDOWN prevents this.

* irmd: Shut down IPCPs before IRMd internalsDimitri Staessens2018-04-261-18/+20
| | | | | | | | | This will shut down IPCPs before destroying IRMd internals. This fixes warnings from IPCPs trying to send messages and send packets upon IRM shutdown. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Unmount stale FUSE mountpointsDimitri Staessens2018-04-261-1/+10
| | | | | | | | This will unmount a stale FUSE mountpoint (an IPCP with the same pid exited ungracefully on the system) before trying to create it. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Fix bad unlinking of old shared memorySander Vrijders2018-04-251-5/+1
| | | | | | | | | | A previous commit tried to stat the shared memory file in case it was already there, but stat does not seem to work for shared memory files. This simply omits the O_EXCL attribute upon creation of the shared memory file, since pids are unique anyway.

* tools: Add check for irm ipcp listSander Vrijders2018-04-251-2/+9
| | | | | | | | | This adds a check in the irm ipcp list command to see if irm_list_ipcps returned an error or not. Before it was only checking if there were zero IPCPs in the system. Signed-off-by: Sander Vrijders <[email protected]> Signed-off-by: Dimitri Staessens <[email protected]>
* lib: Unlink old flow set shared memorySander Vrijders2018-04-251-0/+4
| | | | | | | | | This unlinks previously allocated flow set shared memory. It could be lingering in case an application with the same pid was SIGKILLED, and didn't clean up its flow set shared memory.

* tools: Fix help information for irm ipcpSander Vrijders2018-04-172-3/+8
| | | | | | | | The new command 'irm ipcp list' was not being printed upon printing the usage of 'irm ipcp'. It also fixes an unchecked return value. Signed-off-by: Sander Vrijders <[email protected]> Signed-off-by: Dimitri Staessens <[email protected]>
* ipcpd: Fix truncate of small packetsDimitri Staessens2018-04-051-1/+1
| | | | | | | | The truncate was setting the length to the frame length, instead of the actual payload length to be delivered to the N+1. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Add ethertype checkDimitri Staessens2018-04-051-1/+7
| | | | | | | | An ethertype check was missing for the DIX ethernet IPCP, causing crashes if there is other traffic on the network. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Avoid unnecessary copy in eth writerDimitri Staessens2018-04-051-25/+45
| | | | | | | | | This writes into the Ethernet device directly from the rdrbuff to avoid a copy on the write side in the Ethernet IPCPs. This does not work for the netmap device. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Avoid unnecessary copy in eth readerDimitri Staessens2018-04-052-32/+71

* ipcpd: Enable locking threads to a CPU coreDimitri Staessens2018-04-058-2/+49
| | | | | | | | | This adds a function that locks a thread to a random core. This greatly improves performance on multi-cpu systems. There is no portable way to do this, this only implements it for GNU/Linux. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* tools: Fix hash algorithm in ipcp_bootstrap0.11.2Dimitri Staessens2018-04-051-1/+1

* tools: Increase read buffer in ocbr serverDimitri Staessens2018-03-253-5/+16
| | | | | | | | | | | | The ocbr server had a 1500 byte read buffer, which caused it to perform partial reads on larger SDUs, slowing it down considerably when sendin large packets. The buffer has been increased to 512KB, partial reads disabled, and the client will give an error when larger frames are sent. It will also warn if the size overflows (avoiding a SEGV).

* irmd: Fix memleak when failing to list ipcpsDimitri Staessens2018-03-223-26/+20
| | | | | | | | | The list_ipcps call had a memleak in the failure case. Also fixes a compiler warning for a possible uninitialized variable and renumbers the gpb ipcpd message fields. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Simplify reg/unreg APIDimitri Staessens2018-03-2229-793/+1199
| | | | | | | | | | | | | | | | | | | | The reg/unreg API is simplified to registering and unregistering a single name with a single IPCP. The functionality associated with registering names was moved from the IRMd to the irm tool. The function to list IPCPs was simplified to return all IPCPs in the system with their basic properties needed for management. The above changes led to some needed changes in the irm tool and the management functions that were depending on the previous behaviour of list_ipcps. Command line functionality to list IPCPs in the system is also added to the irm tool. Some older code was refactored.

* irmd: Remove obsolete layer to name mappingsDimitri Staessens2018-03-213-112/+0
| | | | | | | | The IRMd kept a mapping from layer names to registered names, but this is obsolete since the introduction of the query functionality. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Allow disabling partial readDimitri Staessens2018-03-192-8/+20
| | | | | | | | | | | | | | This allows disabling partial reads. It adds a flag FLOWFRNOPART that disables partial reads. Partial read is different from partial delivery (FRCTFPARTIAL), which allows delivery of fragments of an incomplete packet and thus potentially corrupted data. FLOWFRNOPART will never deliver corrupted data (unless FRCTFPARTIAL is also set). If FLOWFRNOPART is set and the buffer provided to flow_read is too small for the SDU, that SDU will be discarded and -EMSGSIZE is returned; Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* tools: Fix help information for oechoDimitri Staessens2018-03-191-4/+4
| | | | | | | | The oecho tool still used its old "echo-app" name in the usage() output. The destination name is also changed to oecho. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Fix reading LSAs in link-state policy0.10.7Dimitri Staessens2018-03-161-2/+2
| | | | | | | | | | | The read buffer had the exact length of a link-state message. With the partial read implemented, we should then do another read() to check if there are more parts of the message (which will return 0). To avoid the additional read() call every time, the buffer was extended by 1 byte. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
