Segmentation fault when terminating upf about gtp5g HOT 4 CLOSED

I do not get a kernel crash, but my entire VM hangs. I have also isolated the problem to "pdr_context_delete". I see the problem even when during PDU session release. I commented out the "pdr_context_delete" in the "gtp5g_del_pdr" call, and then the VM didn't hang.

I think somehow the rcu calls are not proper?

I use Ubuntu 20.04

I reviewed the code as well, the pdi kfree should be at the end, Since pdi is used after the kfree is called.

There is some problem with releasing a gtp interface.

We will fix it soon.
