I'm trying to figure out why that field isn't yet set when you call

First you call apr_socket_create(), which calls apr_socket_create_ex().
apr_socket_create_ex() calls set_socket_vars(*new, family, type, protocol).
set_socket_vars() calls apr_sockaddr_vars_set(sock->remote_addr, family, 0).
apr_sockaddr_vars_set() will set addr->salen to sizeof(struct sockaddr_in).

Can you tell me where this breaks in your situation?  (i.e., why
didn't apr_sockaddr_vars_set() set from->salen to the proper value
before you called apr_socket_recvfrom()?)
