      netfilter: nft_tproxy: restrict to prerouting hook · 18bbc321
      Florian Westphal authored 
      TPROXY is only allowed from prerouting, but nft_tproxy doesn't check this.
This fixes a crash (null dereference) when using tproxy from e.g. output.

      netfilter: conntrack: work around exceeded receive window · cf97769c
      Florian Westphal authored 
      When a TCP sends more bytes than allowed by the receive window, all future
packets can be marked as invalid.
This can clog up the conntrack table because of 5-day default timeout.

Sequence of packets:
 01 initiator > responder: [S], seq 171, win 5840, options [mss 1330,sackOK,TS val 63 ecr 0,nop,wscale 1]
 02 responder > initiator: [S.], seq 33211, ack 172, win 65535, options [mss 1460,sackOK,TS val 010 ecr 63,nop,wscale 8]
 03 initiator > responder: [.], ack 33212, win 2920, options [nop,nop,TS val 068 ecr 010], length 0
 04 initiator > responder: [P.], seq 172:240, ack 33212, win 2920, options [nop,nop,TS val 279 ecr 010], length 68

Window is 5840 starting from 33212 -> 39052.

 05 responder > initiator: [.], ack 240, win 256, options [nop,nop,TS val 872 ecr 279], length 0
 06 responder > initiator: [.], seq 33212:34530, ack 240, win 256, options [nop,nop,TS val 892 ecr 279], length 1318

This is fine, conntrack will flag the connection as having outstanding
data (UNACKED), which lowers the conntrack timeout to 300s.

 07 responder > initiator: [.], seq 34530:35848, ack 240, win 256, options [nop,nop,TS val 892 ecr 279], length 1318
 08 responder > initiator: [.], seq 35848:37166, ack 240, win 256, options [nop,nop,TS val 892 ecr 279], length 1318
 09 responder > initiator: [.], seq 37166:38484, ack 240, win 256, options [nop,nop,TS val 892 ecr 279], length 1318
 10 responder > initiator: [.], seq 38484:39802, ack 240, win 256, options [nop,nop,TS val 892 ecr 279], length 1318

Packet 10 is already sending more than permitted, but conntrack doesn't
validate this (only seq is tested vs. maxend, not 'seq+len').

38484 is acceptable, but only up to 39052, so this packet should
not have been sent (or only 568 bytes, not 1318).

At this point, connection is still in '300s' mode.

Next packet however will get flagged:
 11 responder > initiator: [P.], seq 39802:40128, ack 240, win 256, options [nop,nop,TS val 892 ecr 279], length 326

nf_ct_proto_6: SEQ is over the upper bound (over the window of the receiver) .. LEN=378 .. SEQ=39802 ACK=240 ACK PSH ..

Now, a couple of replies/acks comes in:

 12 initiator > responder: [.], ack 34530, win 4368,
[.. irrelevant acks removed ]
 16 initiator > responder: [.], ack 39802, win 8712, options [nop,nop,TS val 296201291 ecr 2982371892], length 0

This ack is significant -- this acks the last packet send by the
responder that conntrack considered valid.

This means that ack == td_end.  This will withdraw the
'unacked data' flag, the connection moves back to the 5-day timeout
of established conntracks.

 17 initiator > responder: ack 40128, win 10030, ...

This packet is also flagged as invalid.

Because conntrack only updates state based on packets that are
considered valid, packet 11 'did not exist' and that gets us:

nf_ct_proto_6: ACK is over upper bound 39803 (ACKed data not seen yet) .. SEQ=240 ACK=40128 WINDOW=10030 RES=0x00 ACK URG

Because this received and processed by the endpoints, the conntrack entry
remains in a bad state, no packets will ever be considered valid again:

 30 responder > initiator: [F.], seq 40432, ack 2045, win 391, ..
 31 initiator > responder: [.], ack 40433, win 11348, ..
 32 initiator > responder: [F.], seq 2045, ack 40433, win 11348 ..

... all trigger 'ACK is over bound' test and we end up with
non-early-evictable 5-day default timeout.

NB: This patch triggers a bunch of checkpatch warnings because of silly
indent.  I will resend the cleanup series linked below to reduce the
indent level once this change has propagated to net-next.

I could route the cleanup via nf but that causes extra backport work for
stable maintainers.

For some reason ebtables rejects blobs that provide entry points that are
not supported by the table, but what it should instead reject is the
opposite: blobs that DO NOT provide an entry point supported by the table.

t->valid_hooks is the bitmask of hooks (input, forward ...) that will see
packets.  Providing an entry point that is not support is harmless
(never called/used), but the inverse isn't: it results in a crash
because the ebtables traverser doesn't expect a NULL blob for a location
its receiving packets for.

Instead of fixing all the individual checks, do what iptables is doing and
reject all blobs that differ from the expected hooks.

      net: dsa: don't dereference NULL extack in dsa_slave_changeupper() · 855a28f9
      Vladimir Oltean authored 
      When a driver returns -EOPNOTSUPP in dsa_port_bridge_join() but failed
to provide a reason for it, DSA attempts to set the extack to say that
software fallback will kick in.

The problem is, when we use brctl and the legacy bridge ioctls, the
extack will be NULL, and DSA dereferences it in the process of setting
it.

Sergei Antonov proves this using the following stack trace:

bonding: 802.3ad: fix no transmission of LACPDUs

Configuring a bond in a specific order can leave the bond in a state
where it never transmits LACPDUs.

The first patch adds some kselftest infrastructure and the reproducer
that demonstrates the problem. The second patch fixes the issue. The
new third patch makes ad_ticks_per_sec a static const and removes the
passing of this variable via the stack.

      bonding: 802.3ad: fix no transmission of LACPDUs · d745b506
      Jonathan Toppins authored 
      This is caused by the global variable ad_ticks_per_sec being zero as
demonstrated by the reproducer script discussed below. This causes
all timer values in __ad_timer_to_ticks to be zero, resulting
in the periodic timer to never fire.

To reproduce:
Run the script in
`tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh` which
puts bonding into a state where it never transmits LACPDUs.

The if check around the contents of bond_3ad_initialize() is no longer
needed due to commit 5ee14e6d ("bonding: 3ad: apply ad_actor settings
changes immediately") which sets ad.system.sys_mac_addr if any one of
the bonding parameters whos set function calls
bond_3ad_update_ad_actor_settings(). This is because if
ad.system.sys_mac_addr is zero it will be set to the current bond mac
address, this causes the if check to never be true.

we still want to leverage the mdio_bus_phy_suspend()/resume() for
the phy device suspend and resume. In this case, the phy device is
in PHY_READY, and we shouldn't warn about this. It also seems that
the check of mac_managed_pm in WARN_ON is redundant since we already
check this in the entry of mdio_bus_phy_resume(), so drop it.

      In ipa_smem_init(), a Qualcomm SMEM region is allocated (if needed)
and then its virtual address is fetched using qcom_smem_get().  The
physical address associated with that region is also fetched.

The physical address is adjusted so that it is page-aligned, and an
attempt is made to update the size of the region to compensate for
any non-zero adjustment.

But that adjustment isn't done properly.  The physical address is
aligned twice, and as a result the size is never actually adjusted.

Fix this by *not* aligning the "addr" local variable, and instead
making the "phys" local variable be the adjusted "addr" value.

      net: dsa: microchip: keep compatibility with device tree blobs with no phy-mode · 5fbb08eb
      Vladimir Oltean authored 
      DSA has multiple ways of specifying a MAC connection to an internal PHY.
One requires a DT description like this:

	port@0 {
		reg = <0>;
		phy-handle = <&internal_phy>;
		phy-mode = "internal";
	};

(which is IMO the recommended approach, as it is the clearest
description)

but it is also possible to leave the specification as just:

	port@0 {
		reg = <0>;
	}

and if the driver implements ds->ops->phy_read and ds->ops->phy_write,
the DSA framework "knows" it should create a ds->slave_mii_bus, and it
should connect to a non-OF-based internal PHY on this MDIO bus, at an
MDIO address equal to the port address.

There is also an intermediary way of describing things:

	port@0 {
		reg = <0>;
		phy-handle = <&internal_phy>;
	};

In case 2, DSA calls phylink_connect_phy() and in case 3, it calls
phylink_of_phy_connect(). In both cases, phylink_create() has been
called with a phy_interface_t of PHY_INTERFACE_MODE_NA, and in both
cases, PHY_INTERFACE_MODE_NA is translated into phy->interface.

It is important to note that phy_device_create() initializes
dev->interface = PHY_INTERFACE_MODE_GMII, and so, when we use
phylink_create(PHY_INTERFACE_MODE_NA), no one will override this, and we
will end up with a PHY_INTERFACE_MODE_GMII interface inherited from the
PHY.

All this means that in order to maintain compatibility with device tree
blobs where the phy-mode property is missing, we need to allow the
"gmii" phy-mode and treat it as "internal".

    SCI should be updated, because it contains MAC in its first 6
    octets.

That's not entirely correct. The SCI can be based on the MAC address,
but doesn't have to be. We can also use any 64-bit number as the
SCI. When the SCI based on the MAC address, it uses a 16-bit "port
number" provided by userspace, which commit 6fc498bc overwrites
with 1.

In addition, changing the SCI after macsec has been setup can just
confuse the receiver. If we configure the RXSC on the peer based on
the original SCI, we should keep the same SCI on TX.

When the macsec device is being managed by a userspace key negotiation
daemon such as wpa_supplicant, commit 6fc498bc would also
overwrite the SCI defined by userspace.

Fixes: 6fc498bc ("net: macsec: update SCI upon MAC address change.")

      net: dpaa: Fix <1G ethernet on LS1046ARDB · 9dbdfd4a
      Sean Anderson authored 
      As discussed in commit 73a21fa8 ("dpaa_eth: support all modes with
rate adapting PHYs"), we must add a workaround for Aquantia phys with
in-tree support in order to keep 1G support working. Update this
workaround for the AQR113C phy found on revision C LS1046ARDB boards.

Fixes: 12cf1b89 ("net: phy: Add support for AQR113C EPHY")

 "Including fixes from netfilter.

  Current release - regressions:

   - tcp: fix cleanup and leaks in tcp_read_skb() (the new way BPF
     socket maps get data out of the TCP stack)

   - tls: rx: react to strparser initialization errors

   - netfilter: nf_tables: fix scheduling-while-atomic splat

   - net: fix suspicious RCU usage in bpf_sk_reuseport_detach()

  Current release - new code bugs:

   - mlxsw: ptp: fix a couple of races, static checker warnings and
     error handling

  Previous releases - regressions:

   - netfilter:
      - nf_tables: fix possible module reference underflow in error path
      - make conntrack helpers deal with BIG TCP (skbs > 64kB)
      - nfnetlink: re-enable conntrack expectation events

   - net: fix potential refcount leak in ndisc_router_discovery()

  Previous releases - always broken:

   - sched: cls_route: disallow handle of 0

   - neigh: fix possible local DoS due to net iface start/stop loop

   - rtnetlink: fix module refcount leak in rtnetlink_rcv_msg

   - sched: fix adding qlen to qcpu->backlog in gnet_stats_add_queue_cpu

   - virtio_net: fix endian-ness for RSS

   - dsa: mv88e6060: prevent crash on an unused port

   - fec: fix timer capture timing in `fec_ptp_enable_pps()`

   - ocelot: stats: fix races, integer wrapping and reading incorrect
     registers (the change of register definitions here accounts for
     bulk of the changed LoC in this PR)"
