Thanks for the link Nikolay.

Borja, I assume it's the PR submission form that gave you trouble -
sorry for that.  Based on your report it sounds to me like the bug is
in OpenBGPd itself.  If it works on OpenBSD with the TCP_MD5SIG option
though I'd assume it's due to a difference in our (FreeBSD's)
implementation of the option.  Did you look at the OpenBSD/FreeBSD
differences in your investigation?

Another related query, where adding the TCP_SIGNATURE option reportedly
fixed it:
