This patch changes the bpf_sk_storage_*() to take
ARG_PTR_TO_BTF_ID_SOCK_COMMON such that they will work with the pointer
returned by the bpf_skc_to_*() helpers also.
A micro benchmark has been done on a "cgroup_skb/egress" bpf program
which does a bpf_sk_storage_get(). It was driven by netperf doing
a 4096 connected UDP_STREAM test with 64bytes packet.
The stats from "kernel.bpf_stats_enabled" shows no meaningful difference.
The sk_storage_get_btf_proto, sk_storage_delete_btf_proto,
btf_sk_storage_get_proto, and btf_sk_storage_delete_proto are
no longer needed, so they are removed.

ARG_PTR_TO_BTF_ID_SOCK_COMMON
The previous patch allows the networking bpf prog to use the
bpf_skc_to_*() helpers to get a PTR_TO_BTF_ID socket pointer,
e.g. "struct tcp_sock *". It allows the bpf prog to read all the
fields of the tcp_sock.
This patch changes the bpf_sk_release() and bpf_sk_*cgroup_id()
to take ARG_PTR_TO_BTF_ID_SOCK_COMMON such that they will
work with the pointer returned by the bpf_skc_to_*() helpers
also. For example, the following will work:
sk = bpf_skc_lookup_tcp(skb, tuple, tuplen, BPF_F_CURRENT_NETNS, 0);
if (!sk)
return;
tp = bpf_skc_to_tcp_sock(sk);
if (!tp) {
bpf_sk_release(sk);
return;
}
lsndtime = tp->lsndtime;
/* Pass tp to bpf_sk_release() will also work */
bpf_sk_release(tp);
Since PTR_TO_BTF_ID could be NULL, the helper taking
ARG_PTR_TO_BTF_ID_SOCK_COMMON has to check for NULL at runtime.
A btf_id of "struct sock" may not always mean a fullsock. Regardless
the helper's running context may get a non-fullsock or not,
considering fullsock check/handling is pretty cheap, it is better to
keep the same verifier expectation on helper that takes ARG_PTR_TO_BTF_ID*
will be able to handle the minisock situation. In the bpf_sk_*cgroup_id()
case, it will try to get a fullsock by using sk_to_full_sk() as its
skb variant bpf_sk"b"_*cgroup_id() has already been doing.
bpf_sk_release can already handle minisock, so nothing special has to
be done.

There is a constant need to add more fields into the bpf_tcp_sock
for the bpf programs running at tc, sock_ops...etc.
A current workaround could be to use bpf_probe_read_kernel(). However,
other than making another helper call for reading each field and missing
CO-RE, it is also not as intuitive to use as directly reading
"tp->lsndtime" for example. While already having perfmon cap to do
bpf_probe_read_kernel(), it will be much easier if the bpf prog can
directly read from the tcp_sock.
This patch tries to do that by using the existing casting-helpers
bpf_skc_to_*() whose func_proto returns a btf_id. For example, the
func_proto of bpf_skc_to_tcp_sock returns the btf_id of the
kernel "struct tcp_sock".
These helpers are also added to is_ptr_cast_function().
It ensures the returning reg (BPF_REF_0) will also carries the ref_obj_id.
That will keep the ref-tracking works properly.
The bpf_skc_to_* helpers are made available to most of the bpf prog
types in filter.c. The bpf_skc_to_* helpers will be limited by
perfmon cap.
This patch adds a ARG_PTR_TO_BTF_ID_SOCK_COMMON. The helper accepting
this arg can accept a btf-id-ptr (PTR_TO_BTF_ID + &btf_sock_ids[BTF_SOCK_TYPE_SOCK_COMMON])
or a legacy-ctx-convert-skc-ptr (PTR_TO_SOCK_COMMON). The bpf_skc_to_*()
helpers are changed to take ARG_PTR_TO_BTF_ID_SOCK_COMMON such that
they will accept pointer obtained from skb->sk.
Instead of specifying both arg_type and arg_btf_id in the same func_proto
which is how the current ARG_PTR_TO_BTF_ID does, the arg_btf_id of
the new ARG_PTR_TO_BTF_ID_SOCK_COMMON is specified in the
compatible_reg_types[] in verifier.c. The reason is the arg_btf_id is
always the same. Discussion in this thread:
https://lore.kernel.org/bpf/20200922070422.1917351-1-kafai@fb.com/
The ARG_PTR_TO_BTF_ID_ part gives a clear expectation that the helper is
expecting a PTR_TO_BTF_ID which could be NULL. This is the same
behavior as the existing helper taking ARG_PTR_TO_BTF_ID.
The _SOCK_COMMON part means the helper is also expecting the legacy
SOCK_COMMON pointer.
By excluding the _OR_NULL part, the bpf prog cannot call helper
with a literal NULL which doesn't make sense in most cases.
e.g. bpf_skc_to_tcp_sock(NULL) will be rejected. All PTR_TO_*_OR_NULL
reg has to do a NULL check first before passing into the helper or else
the bpf prog will be rejected. This behavior is nothing new and
consistent with the current expectation during bpf-prog-load.
[ ARG_PTR_TO_BTF_ID_SOCK_COMMON will be used to replace
ARG_PTR_TO_SOCK* of other existing helpers later such that
those existing helpers can take the PTR_TO_BTF_ID returned by
the bpf_skc_to_*() helpers.
The only special case is bpf_sk_lookup_assign() which can accept a
literal NULL ptr. It has to be handled specially in another follow
up patch if there is a need (e.g. by renaming ARG_PTR_TO_SOCKET_OR_NULL
to ARG_PTR_TO_BTF_ID_SOCK_COMMON_OR_NULL). ]
[ When converting the older helpers that take ARG_PTR_TO_SOCK* in
the later patch, if the kernel does not support BTF,
ARG_PTR_TO_BTF_ID_SOCK_COMMON will behave like ARG_PTR_TO_SOCK_COMMON
because no reg->type could have PTR_TO_BTF_ID in this case.
It is not a concern for the newer-btf-only helper like the bpf_skc_to_*()
here though because these helpers must require BTF vmlinux to begin
with. ]

check_reg_type() checks whether a reg can be used as an arg of a
func_proto. For PTR_TO_BTF_ID, the check is actually not
completely done until the reg->btf_id is pointing to a
kernel struct that is acceptable by the func_proto.
Thus, this patch moves the btf_id check into check_reg_type().
"arg_type" and "arg_btf_id" are passed to check_reg_type() instead of
"compatible". The compatible_reg_types[] usage is localized in
check_reg_type() now.
The "if (!btf_id) verbose(...); " is also removed since it won't happen.

mptcp: RM_ADDR/ADD_ADDR enhancements
This series include two enhancements for the MPTCP path management,
namely RM_ADDR support and ADD_ADDR echo support, as specified by RFC
sections 3.4.1 and 3.4.2.
1 RM_ADDR support include 9 patches (1-3 and 8-13):
Patch 1 is the helper for patch 2, these two patches add the RM_ADDR
outgoing functions, which are derived from ADD_ADDR's corresponding
functions.
Patch 3 adds the RM_ADDR incoming logic, when RM_ADDR suboption is
received, close the subflow matching the rm_id, and update PM counter.
Patch 8 is the main remove routine. When the PM netlink removes an address,
we traverse all the existing msk sockets to find the relevant sockets. Then
trigger the RM_ADDR signal and remove the subflow which using this local
address, this subflow removing functions has been implemented in patch 9.
Finally, patches 10-13 are the self-tests for RM_ADDR.
2 ADD_ADDR echo support include 7 patches (4-7 and 14-16).
Patch 4 adds the ADD_ADDR echo logic, when the ADD_ADDR suboption has been
received, send out the same ADD_ADDR suboption with echo-flag, and no HMAC
included.
Patches 5 and 6 are the self-tests for ADD_ADDR echo. Patch 7 is a little
cleaning up.
Patch 14 and 15 are the helpers for patch 16. These three patches add
the ADD_ADDR retransmition when no ADD_ADDR echo is received.

This patch added the remove addr and subflow test cases and two new
functions.
The first function run_remove_tests calls do_transfer with two new
arguments, rm_nr_ns1 and rm_nr_ns2, for the numbers of addresses should be
removed during the transfer process in namespace 1 and namespace 2.
If both these two arguments are 0, we do the join test cases with
"mptcp_connect -j" command. Otherwise, do the remove test cases with
"mptcp_connect -r" command.
The second function chk_rm_nr checks the RM_ADDR related mibs's counters.
The output of the test cases looks like this:
11 remove single subflow syn[ ok ] - synack[ ok ] - ack[ ok ]
rm [ ok ] - sf [ ok ]
12 remove multiple subflows syn[ ok ] - synack[ ok ] - ack[ ok ]
rm [ ok ] - sf [ ok ]
13 remove single address syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
rm [ ok ] - sf [ ok ]
14 remove subflow and signal syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
rm [ ok ] - sf [ ok ]
15 remove subflows and signal syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
rm [ ok ] - sf [ ok ]

We add a new list named anno_list in mptcp_pm_data, to record all the

If it has been, we trigger the RM_ADDR signal.
We also check if this address is in conn_list. If it is, we remove the

mlx5-updates-2020-09-22
This series includes mlx5 updates
1) Add support for Connection Tracking offload in NIC mode.
Supporting CT offload in NIC mode on Mellanox cards is useful for
scenarios where the dual port NIC serves as a gateway between 2
networks and forwards traffic between these networks.
Since the traffic is not terminated on the host in this case,
no use of SRIOV VFs and/or switchdev mode is required.
Today Mellanox NIC cards already support offloading of packet forwarding
between physical ports without going to the host so combining it with CT
offloading allows users to create a gateway with forwarding and CT
(Including NAT) offloading capabilities in non-switchdev mode.
To support connection tracking in non-Switchdev mode (Single NIC mode),
we need to make use of the current Connection tracking infrastructure
implemented on top of E-Switch and the mlx5 generic flow table chains
APIs, to make it work on non-Eswitch steering domain e.g. NIC RX domain,
the following was performed:
1.1) Refactor current flow steering chains infrastructure and
updates TC nic mode implementation to use flow table chains.
1.2) Refactor current Connection Tracking (CT) infrastructure to not
assume E-switch backend, and make the CT layer agnostic to
underlying steering mode (E-Switch/NIC)
1.3) Plumbing to support CT offload in NIC mode.
2) Trivial code cleanups.

dpaa2-mac: add PCS support through the Lynx module
This patch set aims to add PCS support in the dpaa2-eth driver by
leveraging the Lynx PCS module.
The first two patches are some missing pieces: the first one adding
support for 10GBASER in Lynx PCS while the second one adds a new
function - of_mdio_find_device - which is helpful in retrieving the PCS
represented as a mdio_device. The final patch adds the glue logic
between phylink and the Lynx PCS module: it retrieves the PCS
represented as an mdio_device and registers it to Lynx and phylink.
From that point on, any PCS callbacks are treated by Lynx, without
dpaa2-eth interaction.
Changes in v2:
- move put_device() after destroy - 3/3

Include PCS support in the dpaa2-eth driver by integrating it with the
new Lynx PCS module. There is not much to talk about in terms of changes
needed in the dpaa2-eth driver since the only steps necessary are to
find the MDIO device representing the PCS, register it to the Lynx PCS
module and then let phylink know if its existence also.
After this, the PCS callbacks will be treated directly by Lynx, without
interraction from dpaa2-eth's part.

Add a helper function which finds the mdio_device structure given a
device tree node. This is helpful for finding the PCS device based on a
DTS node but managing it as a mdio_device instead of a phy_device.

Add support in the Lynx PCS module for the 10GBASE-R mode which is only
used to get the link state, since it offers a single fixed speed.

Currently, ocelot switchdev passes the skb directly to the function that
enqueues it to the list of skb's awaiting a TX timestamp. Whereas the
felix DSA driver first clones the skb, then passes the clone to this
queue.
This matters because in the case of felix, the common IRQ handler, which
is ocelot_get_txtstamp(), currently clones the clone, and frees the
original clone. This is useless and can be simplified by using
skb_complete_tx_timestamp() instead of skb_tstamp_tx().
