Any idea about this error?

@prajithp13 I'm sorry for the late reply.

sock_recvmsg have different signatures depending on the kernel version. I developed it as GCP ubuntu 20.04, and the kernel version is 5.15.

• kernel v5.15

• kernel v4.3

The code needs to be modified to be compiled differently depending on the version, but it is not yet in the development stage.

[prajithp13]

do you have any suggestions for version 5.4.0-125?

[KumKeeHyun]

I confirmed that Ubuntu 18.04(using kernel v5.4.0) did not work.

I checked sock_recvmsg function signature and struct socket, struct msghdr arguments in ubuntu 18.04, but I couldn't find the error.

I don't think I can solve it in the near future. If it is for just execution, i recommend to try it in ubuntu 20.04.
sorry 🙏

Thanks for the update. I wanted to use this in eks for some audit purposes but couldn't get this worked on eks amazon linux 2 as well.
