====================
mptcp: Bug fixes

Here are two bug fixes for the net tree:

Patch 1 fixes a memory leak that could be encountered when clearing the
list of advertised MPTCP addresses.

Patch 2 fixes a protocol issue early in an MPTCP connection, to ensure
both peers correctly understand that the full MPTCP connection handshake
has completed even when the server side quickly sends an ADD_ADDR
option.

      mptcp: full fully established support after ADD_ADDR · 67b12f79
      Matthieu Baerts authored 
      If directly after an MP_CAPABLE 3WHS, the client receives an ADD_ADDR
with HMAC from the server, it is enough to switch to a "fully
established" mode because it has received more MPTCP options.

It was then OK to enable the "fully_established" flag on the MPTCP
socket. Still, best to check if the ADD_ADDR looks valid by looking if
it contains an HMAC (no 'echo' bit). If an ADD_ADDR echo is received
while we are not in "fully established" mode, it is strange and then
we should not switch to this mode now.

But that is not enough. On one hand, the path-manager has be notified
the state has changed. On the other hand, the "fully_established" flag
on the subflow socket should be turned on as well not to re-send the
MP_CAPABLE 3rd ACK content with the next ACK.

Subsequently "ib_map_mr_sg" needs to work with this value ("sg_dma_len")

      net: mscc: ocelot: allow forwarding from bridge ports to the tag_8021q CPU port · c1930148
      Vladimir Oltean authored 
      Currently we are unable to ping a bridge on top of a felix switch which
uses the ocelot-8021q tagger. The packets are dropped on the ingress of
the user port and the 'drop_local' counter increments (the counter which
denotes drops due to no valid destinations).

Dumping the PGID tables, it becomes clear that the PGID_SRC of the user
port is zero, so it has no valid destinations.

But looking at the code, the cpu_fwd_mask (the bit mask of DSA tag_8021q
ports) is clearly missing from the forwarding mask of ports that are
under a bridge. So this has always been broken.

Looking at the version history of the patch, in v7
https://patchwork.kernel.org/project/netdevbpf/patch/20210125220333.1004365-12-olteanv@gmail.com/
the code looked like this:

	/* Standalone ports forward only to DSA tag_8021q CPU ports */
	unsigned long mask = cpu_fwd_mask;

(...)
	} else if (ocelot->bridge_fwd_mask & BIT(port)) {
		mask |= ocelot->bridge_fwd_mask & ~BIT(port);

while in v8 (the merged version)
https://patchwork.kernel.org/project/netdevbpf/patch/20210129010009.3959398-12-olteanv@gmail.com/
it looked like this:

	unsigned long mask;

(...)
	} else if (ocelot->bridge_fwd_mask & BIT(port)) {
		mask = ocelot->bridge_fwd_mask & ~BIT(port);

So the breakage was introduced between v7 and v8 of the patch.

      virtio-net: use NETIF_F_GRO_HW instead of NETIF_F_LRO · dbcf24d1
      Jason Wang authored 
      Commit a02e8964 ("virtio-net: ethtool configurable LRO")
maps LRO to virtio guest offloading features and allows the
administrator to enable and disable those features via ethtool.

This leads to several issues:

- For a device that doesn't support control guest offloads, the "LRO"
  can't be disabled triggering WARN in dev_disable_lro() when turning
  off LRO or when enabling forwarding bridging etc.

- For a device that supports control guest offloads, the guest
  offloads are disabled in cases of bridging, forwarding etc slowing
  down the traffic.

Fix this by using NETIF_F_GRO_HW instead. Though the spec does not
guarantee packets to be re-segmented as the original ones,
we can add that to the spec, possibly with a flag for devices to
differentiate between GRO and LRO.

Further, we never advertised LRO historically before a02e8964
("virtio-net: ethtool configurable LRO") and so bridged/forwarded
configs effectively always relied on virtio receive offloads behaving
like GRO - thus even if this breaks any configs it is at least not
a regression.

Fixes: a02e8964

      vrf: Reset skb conntrack connection on VRF rcv · 09e856d5
      Lahav Schlesinger authored 
      To fix the "reverse-NAT" for replies.

When a packet is sent over a VRF, the POST_ROUTING hooks are called
twice: Once from the VRF interface, and once from the "actual"
interface the packet will be sent from:
1) First SNAT: l3mdev_l3_out() -> vrf_l3_out() -> .. -> vrf_output_direct()
     This causes the POST_ROUTING hooks to run.
2) Second SNAT: 'ip_output()' calls POST_ROUTING hooks again.

Similarly for replies, first ip_rcv() calls PRE_ROUTING hooks, and
second vrf_l3_rcv() calls them again.

As an example, consider the following SNAT rule:
> iptables -t nat -A POSTROUTING -p udp -m udp --dport 53 -j SNAT --to-source 2.2.2.2 -o vrf_1

In this case sending over a VRF will create 2 conntrack entries.
The first is from the VRF interface, which performs the IP SNAT.
The second will run the SNAT, but since the "expected reply" will remain
the same, conntrack randomizes the source port of the packet:
e..g With a socket bound to 1.1.1.1:10000, sending to 3.3.3.3:53, the conntrack
rules are:
udp      17 29 src=2.2.2.2 dst=3.3.3.3 sport=10000 dport=53 packets=1 bytes=68 [UNREPLIED] src=3.3.3.3 dst=2.2.2.2 sport=53 dport=61033 packets=0 bytes=0 mark=0 use=1
udp      17 29 src=1.1.1.1 dst=3.3.3.3 sport=10000 dport=53 packets=1 bytes=68 [UNREPLIED] src=3.3.3.3 dst=2.2.2.2 sport=53 dport=10000 packets=0 bytes=0 mark=0 use=1

i.e. First SNAT IP from 1.1.1.1 --> 2.2.2.2, and second the src port is
SNAT-ed from 10000 --> 61033.

But when a reply is sent (3.3.3.3:53 -> 2.2.2.2:61033) only the later
conntrack entry is matched:
udp      17 29 src=2.2.2.2 dst=3.3.3.3 sport=10000 dport=53 packets=1 bytes=68 src=3.3.3.3 dst=2.2.2.2 sport=53 dport=61033 packets=1 bytes=49 mark=0 use=1
udp      17 28 src=1.1.1.1 dst=3.3.3.3 sport=10000 dport=53 packets=1 bytes=68 [UNREPLIED] src=3.3.3.3 dst=2.2.2.2 sport=53 dport=10000 packets=0 bytes=0 mark=0 use=1

And a "port 61033 unreachable" ICMP packet is sent back.

The issue is that when PRE_ROUTING hooks are called from vrf_l3_rcv(),
the skb already has a conntrack flow attached to it, which means
nf_conntrack_in() will not resolve the flow again.

This means only the dest port is "reverse-NATed" (61033 -> 10000) but
the dest IP remains 2.2.2.2, and since the socket is bound to 1.1.1.1 it's
not received.
This can be verified by logging the 4-tuple of the packet in '__udp4_lib_rcv()'.

The fix is then to reset the flow when skb is received on a VRF, to let
conntrack resolve the flow again (which now will hit the earlier flow).

  running 'bash ./repro'):

 "A patch to avoid a soft lockup in ceph_check_delayed_caps() from Luis
  and a reference handling fix from Jeff that should address some memory
  corruption reports in the snaprealm area.

  Both marked for stable"
