Affected OSes depend on SSH_TUN_COMPAT_AF and SSH_TUN_PREPEND_AF.] Hello OpenSSH developers, I noticed issues with the address family handling for tun devices in the sys_tun_infilter() and sys_tun_outfilter() functions.

In sys_tun_infilter(), the AF is not always converted to network byte order. Please see the first attac...
