2019-10-09l4p/tcp: fix SIGSEGV when reading IPv6 addressMariusz Drost1-1/+1
IPv6 address is obtained through pointer to mbuf (part storing IPv6 addr). Structure which then holds that pointer defines it as a pointer to _m128i data type. Because of that, when code is optimized, instruction vmovdqa is used, which requires data to be aligned to 16-bytes. Pointer from mbuf does not have to be aligned in that way, which may cause SIGSEGV. Solution is to add attribute packed and aligned(1) to structure holding IPv6 address. With that, vmovdqu assembly instruction is used, which is the equivalent of vmovdqa, but for unaligned data.

2019-08-13l4p/tcp: fix removing overlapped dataJielong Zhou3-6/+106
rte_pktmbuf_adj and rte_pktmbuf_trim don't support removing data more than one segment. We reimplemented these funtions to support removing multiple segments.

2019-08-13l4p/tcp_ofo: fix handling out-of-order packetsJielong Zhou3-69/+128
Problems are: 1. ofodb could not be assigned directly, as direct assignment does not copy the mbuf pointer area belonging to it. 2. _ofo_insert_new and _ofo_insert_right doesn't remove overlap correctly. 3. _ofo_insert_new insert new db in wrong position. 4. rx_ofo_reduce sets wrong seq, and would insert overlapped data into rx queue. 5. _ofo_compact may miss compacting some ofodbs and doesn't update partly moved ofodb correctly.

2019-07-02l4p/udp: enqueue fragmented packets as a wholeJielong Zhou1-4/+7
Send or discard fragments of single IP/UDP packet as a whole, because part of fragments could not be reassembled. Also avoid mbuf leak, for former version would never free part of segments which are not sended.

2019-07-01l4p: refactor rx checksum checkJianfeng Tan6-44/+28
For rx checksum check, we put HW and SW ways into one function, with some code clean up. As now we do have CKSUM_UNKNOWN, no need to have dev->rx.ol_flags at all.

Users need two steps to compile DPDK: $ make config -C dpdk $ make -C dpdk We don't see the value for that.

2019-05-23l4p/tcp: fix dropping sequential packetJielong Zhou1-7/+3
When grouping sequential rx packets, some packet may be dropped incorrectly because of total length of packets are larger than receive window size which is out of date. We do not drop the packet, but check it again with updated receive window size. Change-Id: I656864a5f029850da5148b07279a34f22081a342 Signed-off-by: Jielong Zhou <jielong.zjl@antfin.com>

Changes in public API: - removes tle_tcp_stream_synreqs() and tle_tcp_reject() - adds tle_tcp_stream_update_cfg Allocates and fills new stream when final ACK for 3-way handshake is received. Changes in l4fwd sample application: prevents l4fwd to call close() on error event immediately: first try to recv/send remaining data.

2017-02-24Introduce first version of TCP code.Konstantin Ananyev30-0/+8833
Supported functionality: - open/close - listen/accept/connect - send/recv In order to achieve that libtle_udp library was reworked into libtle_l4p library that supports both TCP and UDP protocols. New libtle_timer library was introduced (thanks to Cisco guys and Dave Barach <dbarach@cisco.com> for sharing their timer code with us). Sample application was also reworked significantly to support both TCP and UDP traffic handling. New UT were introduced.
