One may want to have DF set on large packets to support discovering
path mtu and limiting the size of generated packets (hence not
setting the XFRM_STATE_NOPMTUDISC tunnel flag), while still
supporting networks that are incapable of carrying even minimal
sized IPv6 frames (post encapsulation).
Having IPv4 Don't Frag bit set on encapsulated IPv6 frames that
are not larger than the minimum IPv6 mtu of 1280 isn't useful,
because the resulting ICMP Fragmentation Required error isn't
actionable (even assuming you receive it) because IPv6 will not
drop it's path mtu below 1280 anyway. While the IPv4 stack
could prefrag the packets post encap, this requires the ICMP
error to be successfully delivered and causes a loss of the
original IPv6 frame (thus requiring a retransmit and latency
hit). Luckily with IPv4 if we simply don't set the DF flag,
we'll just make further fragmenting the packets some other
router's problems.
We'll still learn the correct IPv4 path mtu through encapsulation
of larger IPv6 frames.
I'm still not convinced this patch is entirely sufficient to make
everything happy... but I don't see how it could possibly
make things worse.

The inner_ipproto saves the inner IP protocol of the plain
text packet. This allows vendor's IPsec feature making offload
decision at skb's features_check and configuring hardware at
ndo_start_xmit.
For example, ConnectX6-DX IPsec device needs the plaintext's
IP protocol to support partial checksum offload on
VXLAN/GENEVE packet over IPsec transport mode tunnel.

In commit 68dc022d04 ("xfrm: BEET mode doesn't support fragments
for inner packets"), it tried to fix the issue that in TX side the
packet is fragmented before the ESP encapping while in the RX side
the fragments always get reassembled before decapping with ESP.
This is not true for IPv6. IPv6 is different, and it's using exthdr
to save fragment info, as well as the ESP info. Exthdrs are added
in TX and processed in RX both in order. So in the above case, the
ESP decapping will be done earlier than the fragment reassembling
in TX side.
Here just remove the fragment check for the IPv6 inner packets to
recover the fragments support for BEET mode.

BEET mode replaces the IP(6) Headers with new IP(6) Headers when sending
packets. However, when it's a fragment before the replacement, currently
kernel keeps the fragment flag and replace the address field then encaps
it with ESP. It would cause in RX side the fragments to get reassembled
before decapping with ESP, which is incorrect.
In Xiumei's testing, these fragments went over an xfrm interface and got
encapped with ESP in the device driver, and the traffic was broken.
I don't have a good way to fix it, but only to warn this out in dmesg.

A situation can occur where the interface bound to the sk is different
to the interface bound to the sk attached to the skb. The interface
bound to the sk is the correct one however this information is lost inside
xfrm_output2 and instead the sk on the skb is used in xfrm_output_resume
instead. This assumes that the sk bound interface and the bound interface
attached to the sk within the skb are the same which can lead to lookup
failures inside ip_route_me_harder resulting in the packet being dropped.
We have an l2tp v3 tunnel with ipsec protection. The tunnel is in the
global VRF however we have an encapsulated dot1q tunnel interface that
is within a different VRF. We also have a mangle rule that marks the
packets causing them to be processed inside ip_route_me_harder.
Prior to commit 31c70d5956 ("l2tp: keep original skb ownership") this
worked fine as the sk attached to the skb was changed from the dot1q
encapsulated interface to the sk for the tunnel which meant the interface
bound to the sk and the interface bound to the skb were identical.
Commit 46d6c5ae95 ("netfilter: use actual socket sk rather than skb sk
when routing harder") fixed some of these issues however a similar
problem existed in the xfrm code.

As on the tx path of vxlan over esp, skb->inner_network_header would be
set on vxlan_xmit() and xfrm4_tunnel_encap_add(), and the later one can
overwrite the former one. It causes skb_udp_tunnel_segment() to use a

This patch is to fix it by calling xfrm_output_gso() instead when the

commit 174e23810c
("sk_buff: drop all skb extensions on free and skb scrubbing") made napi
recycle always drop skb extensions. The additional skb_ext_del() that is
performed via nf_reset on napi skb recycle is not needed anymore.
Most nf_reset() calls in the stack are there so queued skb won't block
'rmmod nf_conntrack' indefinitely.
This removes the skb_ext_del from nf_reset, and renames it to a more
fitting nf_reset_ct().
In a few selected places, add a call to skb_ext_reset to make sure that
no active extensions remain.
I am submitting this for "net", because we're still early in the release
cycle. The patch applies to net-next too, but I think the rename causes
needless divergence between those trees.

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.

6) Validate xfrm template mode, otherwise we can get a stack-out-of-bounds
read in xfrm_state_find. From Sean Tranchetti.

Since commit 222d7dbd25 ("net: prevent dst uses after free")
skb_dst_force() might clear the dst_entry attached to the skb.
The xfrm code don't expect this to happen, so we crash with
a NULL pointer dereference in this case. Fix it by checking
skb_dst(skb) for NULL after skb_dst_force() and drop the packet
in cast the dst_entry was cleared.

An SKB is not on a list if skb->next is NULL.
Codify this convention into a helper function and use it
where we are dequeueing an SKB and need to mark it as such.

We already support setting an output mark at the xfrm_state,
unfortunately this does not support the input direction and
masking the marks that will be applied to the skb. This change
adds support applying a masked value in both directions.
The existing XFRMA_OUTPUT_MARK number is reused for this purpose
and as it is now bi-directional, it is renamed to XFRMA_SET_MARK.
An additional XFRMA_SET_MARK_MASK attribute is added for setting the
mask. If the attribute mask not provided, it is set to 0xffffffff,
keeping the XFRMA_OUTPUT_MARK existing 'full mask' semantics.

In the xfrm_local_error, rcu_read_unlock should be called when afinfo
is not NULL. because xfrm_state_get_afinfo calls rcu_read_unlock
if afinfo is NULL.

We reset the encapsulation field of the skb too early
in xfrm_output. As a result, the GRE GSO handler does
not segment the packets. This leads to a performance
drop down. We fix this by resetting the encapsulation
field right before we do the transformation, when
the inner headers become invalid.

On systems that use mark-based routing it may be necessary for
routing lookups to use marks in order for packets to be routed
correctly. An example of such a system is Android, which uses
socket marks to route packets via different networks.
Currently, routing lookups in tunnel mode always use a mark of
zero, making routing incorrect on such systems.
This patch adds a new output_mark element to the xfrm state and
a corresponding XFRMA_OUTPUT_MARK netlink attribute. The output
mark differs from the existing xfrm mark in two ways:
1. The xfrm mark is used to match xfrm policies and states, while
the xfrm output mark is used to set the mark (and influence
the routing) of the packets emitted by those states.
2. The existing mark is constrained to be a subset of the bits of
the originating socket or transformed packet, but the output
mark is arbitrary and depends only on the state.
The use of a separate mark provides additional flexibility. For
example:
- A packet subject to two transforms (e.g., transport mode inside
tunnel mode) can have two different output marks applied to it,
one for the transport mode SA and one for the tunnel mode SA.
- On a system where socket marks determine routing, the packets
emitted by an IPsec tunnel can be routed based on a mark that
is determined by the tunnel, not by the marks of the
unencrypted packets.
- Support for setting the output marks can be introduced without
breaking any existing setups that employ both mark-based
routing and xfrm tunnel mode. Simply changing the code to use
the xfrm mark for routing output packets could xfrm mark could
change behaviour in a way that breaks these setups.
If the output mark is unspecified or set to zero, the mark is not
set or changed.

Both esp4 and esp6 used to assume that the SKB payload is encrypted
and therefore the inner_network and inner_transport offsets are
not relevant.
When doing crypto offload in the NIC, this is no longer the case
and the NIC driver needs these offsets so it can do TX TCP checksum
offloading.
This patch sets the inner_network and inner_transport members of
the SKB, as well as encapsulation, to reflect the actual positions
of these headers, and removes them only once encryption is done
on the payload.

This patch adds all the bits that are needed to do
IPsec hardware offload for IPsec states and ESP packets.
We add xfrmdev_ops to the net_device. xfrmdev_ops has
function pointers that are needed to manage the xfrm
states in the hardware and to do a per packet
offloading decision.
