Matthew Dillon [Thu, 24 Jun 2004 07:45:22 +0000 (07:45 +0000)]
The route table treats sockaddr data as opaque, which means that the unused
fields in the structure passed to rtalloc() MUST BE ZERO.

The syncache code allocates a governing struct syncache structure which
contains an embedded struct route, but it does not zero this structure.
When used in a mixed IPV4/IPV6 environment, it is possible for a structure
to be allocated for IPV4 whos unused fields for the route lookup (e.g.
sin_port and sin_zero) may contain garbage.  This screws up the route
table lookup and causes the wrong route to be returned.

I believe the proper fix in this case is to rewrite the route table code,
but since that would take a very long time the fix I am committing is
to have tcp_rtlookup() zero out the sockaddr_in before it builds it for
the rtalloc() call.
