I used osmo-pfcp-tool to setup an endecaps session with osmo-upf.

After starting gtp-load-test osmo-upf segfaults:

(gdb) bt
#0  0x0000000000000000 in ?? ()
#1  0x00007ffff698f473 in poll_disp_fds (n_fd=n_fd@entry=5) at select.c:361

(gdb) p *ufd
$4 = {list = {next = 0x616000004a70, prev = 0x6100000015a0}, fd = 7, when = 1, cb = 0x0, data = 0x0, priv_nr = 0}

I attached the config files I used to setup osmo-upf. gbp-load-gen was started with:

gtp-load-gen -g 1 -t 1 -f 1 -e 1 -l 127.0.0.12 -r 127.0.0.11 -s 10.11.0.2 -d 10.11.0.1

Note that the UE ips could be the wrong way around, but the segfault should still be fixed.
