kernelci.org reports failed builds on arc because of what looks
like an old missed 'select' statement:
net/xfrm/xfrm_algo.o: In function `xfrm_probe_algs':
xfrm_algo.c:(.text+0x1e8): undefined reference to `crypto_has_ahash'
I don't see this in randconfig builds on other architectures, but
it's fairly clear we want to select the hash code for it, like we
do for all its other users. As Herbert points out, CRYPTO_BLKCIPHER
is also required even though it has not popped up in build tests.

secpath_set is a wrapper for secpath_dup that will not perform
an allocation if the secpath attached to the skb has a reference count
of one, i.e., it doesn't need to be COW'ed.
Also, secpath_dup doesn't attach the secpath to the skb, it leaves
this to the caller.
Use secpath_set in places that immediately assign the return value to
skb.
This allows to remove skb->sp without touching these spots again.
secpath_dup can eventually be removed in followup patch.

Based on the original work from Arnd Bergmann.
When XFRM_ALGO is not enabled, the new ixgbe IPsec code produces a
link error:
drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.o: In function `ixgbe_ipsec_vf_add_sa':
ixgbe_ipsec.c:(.text+0x1266): undefined reference to `xfrm_aead_get_byname'
Simply selecting XFRM_ALGO from here causes circular dependencies, so
to fix it, we probably want this slightly more complex solution that is
similar to what other drivers with XFRM offload do:
A separate Kconfig symbol now controls whether we include the IPsec
offload code. To keep the old behavior, this is left as 'default y'. The
dependency in XFRM_OFFLOAD still causes a circular dependency but is
not actually needed because this symbol is not user visible, so removing
that dependency on top makes it all work.

Steffen Klassert says:
====================
pull request (net-next): ipsec-next 2018-07-27
1) Extend the output_mark to also support the input direction
and masking the mark values before applying to the skb.
2) Add a new lookup key for the upcomming xfrm interfaces.
3) Extend the xfrm lookups to match xfrm interface IDs.
4) Add virtual xfrm interfaces. The purpose of these interfaces
is to overcome the design limitations that the existing
VTI devices have.
The main limitations that we see with the current VTI are the
following:
VTI interfaces are L3 tunnels with configurable endpoints.
For xfrm, the tunnel endpoint are already determined by the SA.
So the VTI tunnel endpoints must be either the same as on the
SA or wildcards. In case VTI tunnel endpoints are same as on
the SA, we get a one to one correlation between the SA and
the tunnel. So each SA needs its own tunnel interface.
On the other hand, we can have only one VTI tunnel with
wildcard src/dst tunnel endpoints in the system because the
lookup is based on the tunnel endpoints. The existing tunnel
lookup won't work with multiple tunnels with wildcard
tunnel endpoints. Some usecases require more than on
VTI tunnel of this type, for example if somebody has multiple
namespaces and every namespace requires such a VTI.
VTI needs separate interfaces for IPv4 and IPv6 tunnels.
So when routing to a VTI, we have to know to which address
family this traffic class is going to be encapsulated.
This is a lmitation because it makes routing more complex
and it is not always possible to know what happens behind the
VTI, e.g. when the VTI is move to some namespace.
VTI works just with tunnel mode SAs. We need generic interfaces
that ensures transfomation, regardless of the xfrm mode and
the encapsulated address family.
VTI is configured with a combination GRE keys and xfrm marks.
With this we have to deal with some extra cases in the generic
tunnel lookup because the GRE keys on the VTI are actually
not GRE keys, the GRE keys were just reused for something else.
All extensions to the VTI interfaces would require to add
even more complexity to the generic tunnel lookup.
So to overcome this, we developed xfrm interfaces with the
following design goal:
It should be possible to tunnel IPv4 and IPv6 through the same
interface.
No limitation on xfrm mode (tunnel, transport and beet).
Should be a generic virtual interface that ensures IPsec
transformation, no need to know what happens behind the
interface.
Interfaces should be configured with a new key that must match a
new policy/SA lookup key.
The lookup logic should stay in the xfrm codebase, no need to
change or extend generic routing and tunnel lookups.
Should be possible to use IPsec hardware offloads of the underlying
interface.
5) Remove xfrm pcpu policy cache. This was added after the flowcache
removal, but it turned out to make things even worse.
From Florian Westphal.
6) Allow to update the set mark on SA updates.
From Nathan Harold.
7) Convert some timestamps to time64_t.
From Arnd Bergmann.
8) Don't check the offload_handle in xfrm code,
it is an opaque data cookie for the driver.
From Shannon Nelson.
9) Remove xfrmi interface ID from flowi. After this pach
no generic code is touched anymore to do xfrm interface
lookups. From Benedict Wong.
10) Allow to update the xfrm interface ID on SA updates.
From Nathan Harold.
11) Don't pass zero to ERR_PTR() in xfrm_resolve_and_create_bundle.
From YueHaibing.
12) Return more detailed errors on xfrm interface creation.
From Benedict Wong.
13) Use PTR_ERR_OR_ZERO instead of IS_ERR + PTR_ERR.

This patch adds support for virtual xfrm interfaces.
Packets that are routed through such an interface
are guaranteed to be IPsec transformed or dropped.
It is a generic virtual interface that ensures IPsec
transformation, no need to know what happens behind
the interface. This means that we can tunnel IPv4 and
IPv6 through the same interface and support all xfrm
modes (tunnel, transport and beet) on it.

Move the protocol specific config options out to the specific protocols.
With this change net/Kconfig now starts to become readable and serve as a
good basis for further re-structuring.
The menu structure is left almost intact, except that indention is
fixed in most cases. Most visible are the INET changes where several
"depends on INET" are replaced with a single ifdef INET / endif pair.
Several new files were created to accomplish this change - they are
small but serve the purpose that config options are now distributed
out where they belongs.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
