ocserv 1.1.3-1 included in Ubuntu 22.04 with the latest updates does not work properly: when a VPN client tries to connect to the ocserv VPN server, this error message appears in the log:
May 23 23:28:31 my.vpn.server ocserv[15825]: The futex facility returned an unexpected error code.
May 23 23:28:31 my.vpn.server kernel: traps: ocserv-worker[15825] general protection fault ip:7fb8f835e898 sp:7ffeaaa84850 error:0 in libc.so.6[7fb8f835e000+195000]
It is possible to reproduce this bug since I see this error message every time a client tries to connect to the VPN.
Uninstalling the ocserv jammy package and compiling the latest ocsrv version 1.1.6 from source (https://www.infradead.org/ocserv/download/ocserv-1.1.6.tar.xz) solves this issue.
The ocserv changelog for version 1.1.6 says that "Added futex() to the accepted list of seccomp. It is required by Fedora 36’s libc." Maybe it is related to the futex error message seen in Ubuntu. |

Expected result: the OpenConnect client is successfully connected to the VPN.
