echo_server and echo_client sample code builds fail for native_posix_64

[sagarshah-leg]

Building echo_server and echo_client sample code fails for the native_posix_64 board with the following error:

zephyr/subsys/net/ip/tcp2.c:17:10: fatal error: mbedtls/md5.h: No such file or directory
17 | #include <mbedtls/md5.h>
| ^~~~~~~~~~~~~~~
compilation terminated.

I have narrowed it down to CONFIG_NET_TCP config setting in prj.conf.
CONFIG_NET_TCP=y causes the error. Setting it to "n" avoids the error.

To Reproduce
Steps to reproduce the behavior:

1. west build -b native_posix_64 -p always zephyr/samples/net/sockets/echo_server/
2. see build error
3. west build -b native_posix_64 -p always zephyr/samples/net/sockets/echo_client/
4. see build error

Expected behavior
The builds should compile without errors with CONFIG_NET_TCP=y.

Impact
Medium impact, potential showstopper.

@sagarshah-leg I'm not able to reproduce the issue - perhaps try calling west update? It seems that there's a problem with mbed TLS, you're likely using some older revision (there was a bump to mbed TLS 3.0.0 not long ago).

Hi @rlubos I've already performed west update and it didn't solve the issue. For my info, where is it supposed to get the md5.h file from? Zephyr's zephyr/include/ directory doesn't seem to have that mbedtls/ dir.

Zephyr's zephyr/include/ directory doesn't seem to have that mbedtls/ dir.

It's shipped with mbed TLS, it's in modules/crypto/mbedtls/include/ (looking from the west root directory).
