TCP is broken by Zephyr commit 3604c391e #3813
Description
Reported by Marti Bolivar:
Summary
Commit [3604c39|https://github.com/zephyrproject-rtos/zephyr/commit/3604c391e69d253fb985aa6d072283250b454e6e] ("net: udp: Remove NET_UDP_HDR() macro and direct access to net_buf") breaks TCP functionality in Zephyr. This is true even when UDP is enabled.
Additionally, the changes introduced to get_conn() in subsys/net/ip/connection.c by this commit would appear to cause extra problems in configurations where UDP is disabled. This follows because the call to net_udp_get_hdr() will always return NULL in those configurations. The change made in this commit to samples/net/mqtt_publisher/prj_96b_nitrogen.conf also appears to be incorrect and related, unless the intent is to require UDP for TCP to work as well.
Steps to reproduce:
Setup
- Check out zephyr-net-tools from https://github.com/zephyrproject-rtos/net-tools
- Build net-tools as described in https://www.zephyrproject.org/doc/subsystems/networking/qemu_setup.html#networking-with-qemu
- In terminal #1, run ./loop-socat.sh
- In terminal #2, run sudo ./loop-slip-tap.sh
- In terminal #3, run sudo ./echo-server -i tap0
Success case
Check out the commit immediately preceeding 3604c39, which is 8476da9, and run the echo_client application targeting QEMU for x86, with the project configuration altered to allow for linux <--> qemu communication as described in prj_qemu_x86.conf.
Observe the echo client application runs successfully.
