Did you try it? on current? I am running 201010 Current. From the code
I see some comments like "/* XXX add support for proxied addresses
*/". For me it looks like the code for proxy is half done, if I may
say so myself :P
see this method in net80211/ieee80211_mesh.c
/*
* Iterate the routing table and locate the next hop.
*/
static struct ieee80211_node *
mesh_find_txnode(struct ieee80211vap *vap,
const uint8_t dest[IEEE80211_ADDR_LEN])
{
...
if ((rt->rt_flags & IEEE80211_MESHRT_FLAGS_VALID) =3D=3D 0 ||
(rt->rt_flags & IEEE80211_MESHRT_FLAGS_PROXY)) {
IEEE80211_NOTE_MAC(vap, IEEE80211_MSG_MESH, dest,
"%s: !valid or proxy, flags 0x%x", __func__, rt->rt_flags);
/* XXX stat */
return NULL;
}
...
}
it stops if the dest node is a proxy. Then after failing in forwarding
it goes out (=3D=3D discard frame?), I put a print message there to verify
that it goes out:
static int
mesh_input(struct ieee80211_node *ni, struct mbuf *m, int rssi, int nf)
{
...
/*
* Potentially forward packet. See table s36 (p140)
* for the rules. XXX tap fwd'd packets not for us?
*/
if (dir =3D=3D IEEE80211_FC1_DIR_FROMDS ||
!mesh_isucastforme(vap, wh, mc)) {
mesh_forward(vap, m, mc);
if (dir =3D=3D IEEE80211_FC1_DIR_DSTODS)
goto out;
/* NB: fall thru to deliver mcast frames locally */
}
...
}
I am puzzeled... everyone says it works, did I miss something?! :P
