[PATCH net-next v3 0/2] fix icmp error source address over xfrm tunnel

[Antony Antony <antony.antony@secunet.com>]

Hi,
This fix, originally intended for XFRM/IPsec, has been recommended by
Steffen Klassert to submit to the net tree.

The patch addresses a minor issue related to the IPv4 source address of
ICMP error messages, which originated from an old 2011 commit:

415b3334a21a ("icmp: Fix regression in nexthop resolution during replies.")

The omission of a "Fixes" tag  in the following commit is deliberate
to prevent potential test failures and subsequent regression issues
that may arise from backporting this patch all stable kerenels.
This is a minor fix, anot not security fix.
With a seleftest I am submitting this to net-next tree.

v2->v3 : fix testscript. The IFS, space, got mangled.
v1->v2 : add kernel selftest script
