Revision 05fb3dbda187bbd9cc1cd0e97e5d6595af570ac6 authored by Robin Murphy on 30 July 2020, 09:56:49 UTC, committed by Will Deacon on 30 July 2020, 16:01:38 UTC
Although iph is expected to point to at least 20 bytes of valid memory,
ihl may be bogus, for example on reception of a corrupt packet. If it
happens to be less than 5, we really don't want to run away and
dereference 16GB worth of memory until it wraps back to exactly zero...
