My version of the patch must have changed the default driver or
something along these lines.

tcp_init.c:373 in MPICH reads this:

--8<---------------cut here---------------start------------->8---
    /* If we don't have an IP address, try to get it from the name */
    if (!ifaddrFound) {
        mpi_errno = MPL_get_sockaddr(ifname_string, p_addr);
        MPIR_ERR_CHKANDJUMP2(mpi_errno, mpi_errno, MPI_ERR_OTHER, "**gethostbyname", "**gethostbyname %s %d", ifname_string, h_errno);
    }
--8<---------------cut here---------------end--------------->8---

‘MPL_get_sockaddr’ uses ‘getifaddrs’ to get the list of local
interfaces, which in turn is implemented in terms of netlink requests in
libc.

I tried to reproduce it without success, but I guess my example MPI
program is too simple to trigger the issue:

Ideas?

Could you perhaps strace the pt-scotch test that fails so we can see if
there’s anything obvious, such as code that browses /sys or similar?

TIA,
Ludo’.
