Subject: [PATCH 3/7] ip-xfrm: support 'proto any' with 'sport' and 'dport'
|
||
|

|
When creating an IPsec SA that sets 'proto any' (IPPROTO_IP) and
|
||
|
|
specifies 'sport' and 'dport' at the same time in selector, the
|
||
|
|
following error is issued:
|
||
|
|
|
||
|
|
"sport" and "dport" are invalid with proto=ip
|
||
|
|
|
||
|
|
However using IPPROTO_IP with ports is completely legal and necessary
|
||
|
|
when one wants to share the SA on both TCP and UDP. One of the
|
||
|
|
applications requiring sharing SAs is 3GPP IMS AKA authentication.
