fscrypt: fix keyring memory leak on mount failure
Under memory pressure, enetc_refill_rx_ring() may fail, and when called
during the enetc_open() -> enetc_setup_rxbdr() procedure, this is not
checked for.
An extreme case of memory pressure will result in exactly zero buffers
being allocated for the RX ring, and in such a case it is expected that
hardware drops all RX packets due to lack of buffers.
This does not happen, because the reset-default value of the consumer
and produces index is 0, and this makes the ENETC think that all buffers
have been initialized and that it owns them (when in reality none were).
The hardware guide explains this best:
| Configure the receive ring producer index register RBaPIR with a value
| of 0. The producer index is initially configured by software but owned
| by hardware after the ring has been enabled. Hardware increments the
| index when a frame is received which may consume one or more BDs.
| Hardware is not allowed to increment the producer index to match the
| consumer index since it is used to indicate an empty condition. The ring
| can hold at most RBLENR[LENGTH]-1 received BDs.
|
| Configure the receive ring consumer index register RBaCIR. The
| consumer index is owned by software and updated during operation of the
| of the BD ring by software, to indicate that any receive data occupied
| in the BD has been processed and it has been prepared for new data.
| - If consumer index and producer index are initialized to the same
| value, it indicates that all BDs in the ring have been prepared and
| hardware owns all of the entries.
| - If consumer index is initialized to producer index plus N, it would
| indicate N BDs have been prepared. Note that hardware cannot start if
| only a single buffer is prepared due to the restrictions described in
| (2).
| - Software may write consumer index to match producer index anytime
| while the ring is operational to indicate all received BDs prior have
| been processed and new BDs prepared for hardware.
Normally, the value of rx_ring->rcir (consumer index) is brought in sync
with the rx_ring->next_to_use software index, but this only happens if
page allocation ever succeeded.
When PI==CI==0, the hardware appears to receive frames and write them to
DMA address 0x0 (?!), then set the READY bit in the BD.
The enetc_clean_rx_ring() function (and its XDP derivative) is naturally
not prepared to handle such a condition. It will attempt to process
those frames using the rx_swbd structure associated with index i of the
RX ring, but that structure is not fully initialized (enetc_new_page()
does all of that). So what happens next is undefined behavior.
To operate using no buffer, we must initialize the CI to PI + 1, which
will block the hardware from advancing the CI any further, and drop
everything.
The issue was seen while adding support for zero-copy AF_XDP sockets,
where buffer memory comes from user space, which can even decide to
supply no buffers at all (example: "xdpsock --txonly"). However, the bug
is present also with the network stack code, even though it would take a
very determined person to trigger a page allocation failure at the
perfect time (a series of ifup/ifdown under memory pressure should
eventually reproduce it given enough retries).

When tx_port_ts is set, the driver diverts all UPD traffic over PTP port
to a dedicated PTP-SQ. The SKBs are cached until the wire-CQE arrives.
When the packet size is greater then MTU, the firmware might drop it and
the packet won't be transmitted to the wire, hence the wire-CQE won't
reach the driver. In this case the SKBs are accumulated in the SKB fifo.
Add room check to consider the PTP-SQ SKB fifo, when the SKB fifo is

An offloaded SA stops receiving after about 2^32 + replay_window
packets. For example, when SA reaches <seq-hi 0x1, seq 0x2c>, all
subsequent packets get dropped with SA-icv-failure (integrity_failed).
To reproduce the bug:
- ConnectX-6 Dx with crypto enabled (FW 22.30.1004)
- ipsec.conf:
nic-offload = yes
replay-window = 32
esn = yes
salifetime=24h
- Run netperf for a long time to send more than 2^32 packets
netperf -H <device-under-test> -t TCP_STREAM -l 20000
When 2^32 + replay_window packets are received, the replay window
moves from the 2nd half of subspace (overlap=1) to the 1st half
(overlap=0). The driver then updates the 'esn' value in NIC
(i.e. seq_hi) as follows.
seq_hi = xfrm_replay_seqhi(seq_bottom)
new esn in NIC = seq_hi + 1
The +1 increment is wrong, as seq_hi already contains the correct
seq_hi. For example, when seq_hi=1, the driver actually tells NIC to
use seq_hi=2 (esn). This incorrect esn value causes all subsequent
packets to fail integrity checks (SA-icv-failure). So, do not
increment.

As explained by Julian, fib_nh_scope is related to fib_nh_gw4, but
fib_info_update_nhc_saddr() needs the scope of the route, which is
the scope "before" fib_nh_scope, ie fib_nh_scope - 1.
This patch fixes the problem described in commit 747c143072 ("ip: fix
dflt addr selection for connected nexthop").
Fixes: 597cfe4fc3 ("nexthop: Add support for IPv4 nexthops")

This reverts commit 747c143072.
As explained by Julian, nhc_scope is related to nhc_gw, not to the route.
Revert the original patch. The initial problem is fixed differently in the
next commit.

Avoid the PHY library call unnecessarily into the suspend/resume
functions by setting phydev->mac_managed_pm to true. The SYSTEMPORT
driver essentially does exactly what mdio_bus_phy_resume() does by
calling phy_resume().

It is not allowed to call kfree_skb() from hardware interrupt context
or with interrupts being disabled. The skb is unlinked from the queue,
so it can be freed after spin_unlock_irqrestore().

====================
openvswitch: syzbot splat fix and introduce selftest
Syzbot recently caught a splat when dropping features from
openvswitch datapaths that are in-use. The WARN() call is
definitely too large a hammer for the situation, so change
to pr_warn.
Second patch in the series introduces a new selftest suite which
can help show that an issue is fixed. This change might be
more suited to net-next tree, so it has been separated out
as an additional patch and can be either applied to either tree
based on preference.

Previous commit resolves a WARN splat that can be difficult to reproduce,
but with the ovs-dpctl.py utility, it can be trivial. Introduce a test
case which creates a DP, and then downgrades the feature set. This will
include a utility 'ovs-dpctl.py' that can be extended to do additional
tests and diagnostics.

As noted by Paolo Abeni, pr_warn doesn't generate any splat and can still
preserve the warning to the user that feature downgrade occurred. We
likely cannot introduce other kinds of checks / enforcement here because
syzbot can generate different genl versions to the datapath.
