This imports basic TFO server tests from google/packetdrill.
The repository has two versions of tests for most scenarios; one uses
the non-experimental option (34), and the other uses the experimental
option (255) with 0xF989.
This only imports the following tests of the non-experimental version
placed in [0]. I will add a specific test for the experimental option
handling later.
| TFO | Cookie | Payload |
---------------------------+-----+--------+---------+
basic-rw.pkt | yes | yes | yes |
basic-zero-payload.pkt | yes | yes | no |
basic-cookie-not-reqd.pkt | yes | no | yes |
basic-non-tfo-listener.pkt | no | yes | yes |
pure-syn-data.pkt | yes | no | yes |
The original pure-syn-data.pkt missed setsockopt(TCP_FASTOPEN) and did
not test TFO server in some scenarios unintentionally, so setsockopt()
is added where needed. In addition, non-TFO scenario is stripped as
it is covered by basic-non-tfo-listener.pkt. Also, I added basic- prefix.
