Dear linux sctp mailing list, I am a master student of the Münster University of Applied Sciences (Germany). In the last months I have developed a test suite in packetdrill for the partial reliability extension of sctp. Many test cases can run the Linux and FreeBSD kernel and therefore I have found some potential problems / bugs with my test suite. I want to share and discuss these potential issues with you on the mailing list. Because the testsuite is published on Github with a permissive license (bsd-style) you can get all developed tests by cloning the following repository with git: https://github.com/nplab/PR_SCTP_Testsuite. On Github I also have documented the test-results of the test-suite in README-Files. Please note that only the tests from the subfolder forward-tsn are applicable for Linux, because the tests in the other directories require support for the NR-SACK and the User Message Interleaving extension. Please also note that you need the nplab-version of packetdrill from https://github.com/nplab/packetdrill in order to run the tests on linux. The original version of packetdrill from google misses SCTP support. I will send a couple of mails, one for every potential issue that I have found with the test suite on kernel 4.4.0-x under ubuntu 16.04. All mails will contain a short description of the potential problem and a link to the test-case or multiple test-cases that were used to detect this behaviour. Yours sincerely, Julian Cordes
