https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218095 Bug ID: 218095 Summary: security/mbedtls Product: Ports & Packages Version: Latest Hardware: arm OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: tijl@FreeBSD.org Reporter: gmc@metro.cx CC: freebsd-arm@FreeBSD.org Assignee: tijl@FreeBSD.org CC: freebsd-arm@FreeBSD.org Flags: maintainer-feedback?(tijl@FreeBSD.org) Created attachment 181161 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D181161&action= =3Dedit client openvpn config When upgrading my arm router that is running openvpn-mbedtls, the upgrade of mbedtls to 2.4.2_1 breaks the ability to send traffic over the openvpn tunn= el (a tap ethernet bridge). Apart from the upgrade I did not change the configuration of the openvpn cl= ient nor that of the server, keys were the same (validity several years from now= ). Both server and client are ntp synced. The logs on both the server and client side indicate no issue, and would sh= ow the same as successful connections before the mbedtls upgrade. tcpdump on t= he server even showed what looked like keep-alive pings and responses from the client (every 10 seconds I would see a udp packet from port 1194 on the ser= ver to the client and about one second later another udp packet in the opposite direction). At some point I noticed that the client openvpn was using 80 to 90% cpu continuously, while normally it uses very little (up to 5% normally, 20% at most when there is lots of traffic).=20 I then changed the server to use openvpn with openssl. That did not change anything. Then I changed the client to openvpn with openssl and instantly (without changing anything else) everything was back to normal. Traffic wou= ld flow immediately after the openvpn connection was initiated. The server is an amd64 machine in a datacenter, the client an armv5 device = at home behind an adsl connection. Packages for the armv5 device I compile with poudriere on the amd64 machine. Attached a number of files: the client and server openvpn config files and = the poudriere build log. Not sure where to report this, and if anyone is even interested in this iss= ue. I'm now running openvpn with openssl. I'd rather use mbedtls, but the curre= nt situation is an acceptable work-around. --=20 You are receiving this mail because: You are the assignee for the bug.=
