bpf_skb_adjust_room calls skb_cow on grow.
This expensive operation can be avoided in the fast path when the only
other clone has released the header. This is the common case for TCP,
where one headerless clone is kept on the retransmit queue.
It is safe to do so even when touching the gso fields in skb_shinfo.
Regular tunnel encap with iptunnel_handle_offloads takes the same
optimization.
The tcp stack unclones in the unlikely case that it accesses these
fields through headerless clones packets on the retransmit queue (see
__tcp_retransmit_skb).
If any other clones are present, e.g., from packet sockets,
skb_cow_head returns the same value as skb_cow().

====================
This series adds the necessary helpers to determine wheter a given
(encapsulated) TCP packet belongs to a connection known to the network stack.
* bpf_skc_lookup_tcp gives access to request and timewait sockets
* bpf_tcp_check_syncookie identifies the final 3WHS ACK when syncookies
are enabled
The goal is to be able to implement load-balancing approaches like
glb-director [1] or Beamer [2] in pure eBPF. Specifically, we'd like to replace
the functionality of the glb-redirect kernel module [3] by an XDP program or
tc classifier.
Changes in v3:
* Fix missing check for ip4->ihl
* Only cast to unsigned long in BPF_CALLs
Changes in v2:
* Rename bpf_sk_check_syncookie to bpf_tcp_check_syncookie.
* Add bpf_skc_lookup_tcp. Without it bpf_tcp_check_syncookie doesn't make sense.
* Check tcp_synq_no_recent_overflow() in bpf_tcp_check_syncookie.
* Check th->syn in bpf_tcp_check_syncookie.
* Require CONFIG_IPV6 to be a built in.

Using bpf_skc_lookup_tcp it's possible to ascertain whether a packet
belongs to a known connection. However, there is one corner case: no
sockets are created if SYN cookies are active. This means that the final
ACK in the 3WHS is misclassified.
Using the helper, we can look up the listening socket via
bpf_skc_lookup_tcp and then check whether a packet is a valid SYN
cookie ACK.

net: refactor ndo_select_queue()
Currently, on most devices implementing ndo_select_queue(), we get 2
indirect calls per xmit packet, at least in some scenarios.
We can avoid one of such indirect calls refactoring the ndo_select_queue()
usage so that we don't need anymore the 'fallback' argument.
The first patch renames a helper used later as a public API, the second one
changes the af packet implementation so that it uses the common infrastructure
to select the xmit queue, and the second patch drops the now unneeded argument
from ndo_select_queue().
Alternatively we could use the INDIRECT_CALL_WRAPPER infrastructure to avoid
the fallback indirect call in the common case, but this solution allows also
for some code cleanup.
v1 -> v2:
- renamed select queue helpers, as per Eric's and David's suggestions
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
After the previous patch, all the callers of ndo_select_queue()
provide as a 'fallback' argument netdev_pick_tx.
The only exceptions are nested calls to ndo_select_queue(),
which pass down the 'fallback' available in the current scope
- still netdev_pick_tx.
We can drop such argument and replace fallback() invocation with
netdev_pick_tx(). This avoids an indirect call per xmit packet
in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen)
with device drivers implementing such ndo. It also clean the code
a bit.

Currently packet_pick_tx_queue() is the only caller of
ndo_select_queue() using a fallback argument other than
netdev_pick_tx.
Leveraging rx queue, we can obtain a similar queue selection
behavior using core helpers. After this change, ndo_select_queue()
is always invoked with netdev_pick_tx() as fallback.
We can change ndo_select_queue() signature in a followup patch,
dropping an indirect call per transmitted packet in some scenarios
(e.g. TCP syn and XDP generic xmit)
This changes slightly how af packet queue selection happens when
PACKET_QDISC_BYPASS is set. It's now more similar to plan dev_queue_xmit()
tacking in account both XPS and TC mapping.

Added support for AES128-CCM based record encryption. AES128-CCM is

notable difference between the two is that while invoking AES128-CCM
operation, the salt||nonce (which is passed as IV) has to be prefixed
with a hardcoded value '2'. Further, CCM implementation in kernel
requires IV passed in crypto_aead_request() to be full '16' bytes.
Therefore, the record structure 'struct tls_rec' has been modified to
reserve '16' bytes for IV. This works for both GCM and CCM based cipher.

Currently the Phy driver's link_change_notify callback is called
whenever the state machine is run (every second if polling), no matter
whether the state changed or not. This isn't needed and may confuse
users considering the name of the callback. Actually it contradicts
its kernel-doc description. Therefore let's change the behavior and
call this callback only in case of an actual state change.
This requires changes to the at803x and rockchip drivers.
at803x can be simplified so that it reacts on a state change to
PHY_NOLINK only.
The rockchip driver can also be much simplified. We simply re-init
the AFE/DSP registers whenever we change to PHY_RUNNING and speed
is 100Mbps. This causes very small overhead because we do this even
if the speed was 100Mbps already. But this is negligible and
I think justified by the much simpler code.
Changes are compile-tested only.
A little bit problematic seems to be to find somebody with the
hardware to test the changes to the two PHY drivers. See also [0].
David may be able to test the Rockchip driver.

Currently we set the default number of Tx and Rx descriptors to 128 by
default. For Rx this amounts to a full page (assuming 4K pages) because
