This reverts commit d9142e1cf3bbdaf21337767114ecab26fe702d47.
The test is supposed to run cleanly with TLS is disabled,
to test compatibility with TCP behavior. I can't repro
the failure [1], the problem should be debugged rather
than papered over.

The current autocork algorithms will delay the data transmission
in BH context to smc_release_cb() when sock_lock is hold by user.
So there is a possibility that when connection is being actively
closed (sock_lock is hold by user now), some corked data still
remains in sndbuf, waiting to be sent by smc_release_cb(). This
will cause:
- smc_close_stream_wait(), which is called under the sock_lock,
has a high probability of timeout because data transmission is
delayed until sock_lock is released.
- Unexpected data sends may happen after connction closed and use
the rtoken which has been deleted by remote peer through
LLC_DELETE_RKEY messages.
So this patch will try to send out the remaining corked data in
sndbuf before active close process, to ensure data integrity and
avoid unexpected data transmission after close.

The bug is here:
return rule;
The list iterator value 'rule' will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the
iterator value will be NULL if the list is empty or no element
is found.
To fix the bug, return 'rule' when found, otherwise return NULL.

This fixes the compilation error.

Halil Pasic points out [1] that the full revert of that commit (revert
in bddac7c1e02b), and that a partial revert that only reverts the
problematic case, but still keeps some of the cleanups is probably
better. 
And that partial revert [2] had already been verified by Oleksandr
Natalenko to also fix the issue, I had just missed that in the long
discussion.
So let's reinstate the cleanups from commit aa6f8dcbab47 ("swiotlb:
rework "fix info leak with DMA_FROM_DEVICE""), and effectively only
revert the part that caused problems.

The objcg is not cleared and put for kfence object when it is freed,
which could lead to memory leak for struct obj_cgroup and wrong

Since the last freed object's objcg is not cleared,
mem_cgroup_from_obj() could return the wrong memcg when this kfence
object, which is not charged to any objcgs, is reallocated to other
users.

When switching zones or network namespaces without doing a ct clear in
between, it is now leaking a reference to the old ct entry. That's
because tcf_ct_skb_nfct_cached() returns false and
tcf_ct_flow_table_lookup() may simply overwrite it.
The fix is to, as the ct entry is not reusable, free it already at
tcf_ct_skb_nfct_cached().

When the link layer is terminating, x25->neighbour will be set to NULL
in x25_disconnect(). As a result, it could cause null-ptr-deref bugs in
x25_sendmsg(),x25_recvmsg() and x25_connect(). One of the bugs is
shown below.
(Thread 1) | (Thread 2)
x25_link_terminated() | x25_recvmsg()
x25_kill_by_neigh() | ...
x25_disconnect() | lock_sock(sk)
... | ...
x25->neighbour = NULL //(1) |
... | x25->neighbour->extended //(2)
The code sets NULL to x25->neighbour in position (1) and dereferences
x25->neighbour in position (2), which could cause null-ptr-deref bug.
This patch adds lock_sock() in x25_kill_by_neigh() in order to synchronize
with x25_sendmsg(), x25_recvmsg() and x25_connect(). What`s more, the
sock held by lock_sock() is not NULL, because it is extracted from x25_list
and uses x25_list_lock to synchronize.

This reverts commit aa6f8dcbab473f3a3c7454b74caa46d36cdc5d13.
It turns out this breaks at least the ath9k wireless driver, and
possibly others.
What the ath9k driver does on packet receive is to set up the DMA
transfer with:
int ath_rx_init(..)
..
bf->bf_buf_addr = dma_map_single(sc->dev, skb->data,
common->rx_bufsize,
DMA_FROM_DEVICE);
and then the receive logic (through ath_rx_tasklet()) will fetch
incoming packets
static bool ath_edma_get_buffers(..)
..
dma_sync_single_for_cpu(sc->dev, bf->bf_buf_addr,
common->rx_bufsize, DMA_FROM_DEVICE);
ret = ath9k_hw_process_rxdesc_edma(ah, rs, skb->data);
if (ret == -EINPROGRESS) {
/*let device gain the buffer again*/
dma_sync_single_for_device(sc->dev, bf->bf_buf_addr,
common->rx_bufsize, DMA_FROM_DEVICE);
return false;
}
and it's worth noting how that first DMA sync:
dma_sync_single_for_cpu(..DMA_FROM_DEVICE);
is there to make sure the CPU can read the DMA buffer (possibly by
copying it from the bounce buffer area, or by doing some cache flush).
The iommu correctly turns that into a "copy from bounce bufer" so that
the driver can look at the state of the packets.
In the meantime, the device may continue to write to the DMA buffer, but
we at least have a snapshot of the state due to that first DMA sync.
But that _second_ DMA sync:
dma_sync_single_for_device(..DMA_FROM_DEVICE);
is telling the DMA mapping that the CPU wasn't interested in the area
because the packet wasn't there. In the case of a DMA bounce buffer,
that is a no-op.
Note how it's not a sync for the CPU (the "for_device()" part), and it's
not a sync for data written by the CPU (the "DMA_FROM_DEVICE" part).
Or rather, it _should_ be a no-op. That's what commit aa6f8dcbab47
broke: it made the code bounce the buffer unconditionally, and changed
the DMA_FROM_DEVICE to just unconditionally and illogically be
DMA_TO_DEVICE.
[ Side note: purely within the confines of the swiotlb driver it wasn't
entirely illogical: The reason it did that odd DMA_FROM_DEVICE ->
DMA_TO_DEVICE conversion thing is because inside the swiotlb driver,
it uses just a swiotlb_bounce() helper that doesn't care about the
whole distinction of who the sync is for - only which direction to
bounce.
So it took the "sync for device" to mean that the CPU must have been
the one writing, and thought it meant DMA_TO_DEVICE. ]
Also note how the commentary in that commit was wrong, probably due to
that whole confusion, claiming that the commit makes the swiotlb code
"bounce unconditionally (that is, also
when dir == DMA_TO_DEVICE) in order do avoid synchronising back stale
data from the swiotlb buffer"
which is nonsensical for two reasons:
- that "also when dir == DMA_TO_DEVICE" is nonsensical, as that was
exactly when it always did - and should do - the bounce.
- since this is a sync for the device (not for the CPU), we're clearly
fundamentally not coping back stale data from the bounce buffers at
all, because we'd be copying *to* the bounce buffers.
So that commit was just very confused. It confused the direction of the
synchronization (to the device, not the cpu) with the direction of the
DMA (from the device).

Currently, function hclge_mdio_read() will return 0 if during reset(the
cmd state will be set to disable).
If use general phy driver, the phy_state_machine() will update phy speed
every second in function genphy_read_status_fixed() when PHY is set to
autoneg off, no matter of link down or link up.
If phy driver happens to read BMCR register during reset, phy speed will
be updated to 10Mpbs as BMCR register value is 0. So it may call phy can
not link up if previous speed is not 10Mpbs.
To fix this problem, function hclge_mdio_read() should return -EBUSY if
the cmd state is disable. So does function hclge_mdio_write().

We support short command 'rec*' for 'record' and 'rep*' for 'report' in
lots of sub-commands, but the matching is not quite strict currnetly.
It may be puzzling sometime, like we mis-type a 'recport' to report but
it will perform 'record' in fact without any message.
To fix this, add a check to ensure that the short cmd is valid prefix
of the real command.

The purpose of the last test case is to test VXLAN encapsulation and
decapsulation when the underlay lookup takes place in a non-default VRF.
This is achieved by enslaving the physical device of the tunnel to a
VRF.
The binding of the VXLAN UDP socket to the VRF happens when the VXLAN
device itself is opened, not when its physical device is opened. This
was also mentioned in the cited commit ("tests that moving the underlay
from a VRF to another works when down/up the VXLAN interface"), but the
test did something else.
Fix it by reopening the VXLAN device instead of its physical device.
Before:
# ./test_vxlan_under_vrf.sh
Checking HV connectivity [ OK ]
Check VM connectivity through VXLAN (underlay in the default VRF) [ OK ]
Check VM connectivity through VXLAN (underlay in a VRF) [FAIL]
After:
# ./test_vxlan_under_vrf.sh
Checking HV connectivity [ OK ]
Check VM connectivity through VXLAN (underlay in the default VRF) [ OK ]
Check VM connectivity through VXLAN (underlay in a VRF) [ OK ]

A Broadcom AC201 PHY (same entry as 5241) would be flagged by the
Broadcom UniMAC MDIO controller as not completing the turn around
properly since the PHY expects 65 MDC clock cycles to complete a write
cycle, and the MDIO controller was only sending 64 MDC clock cycles as
determined by looking at a scope shot.
This would make the subsequent read fail with the UniMAC MDIO controller
command field having MDIO_READ_FAIL set and we would abort the
brcm_fet_config_init() function and thus not probe the PHY at all.
After issuing a software reset, wait for at least 1ms which is well
above the 1us reset delay advertised by the datasheet and issue a dummy
read to let the PHY turn around the line properly. This read
specifically ignores -EIO which would be returned by MDIO controllers
checking for the line being turned around.
If we have a genuine reaad failure, the next read of the interrupt
status register would pick it up anyway.

My latest patch, attempting to fix the refcount leak in a minimal
way turned out to add a new bug.
Whenever the bind operation fails before we attempt to grab
a reference count on a device, we might release the device refcount
of a prior successful bind() operation.
syzbot was not happy about this [1].
Note to stable teams:
Make sure commit b37a46683739 ("netdevice: add the case if dev is NULL")
is already present in your trees.

Currently, when PF set VF VLAN, it sends notify mailbox to VF
if VF alive. VF stop its traffic, and send request mailbox
to PF, then PF updates VF VLAN. It's a bit complex. If VF is
killed before sending request, PF will not set VF VLAN without
any log.
This patch refines the process, PF can set VF VLAN direclty,
and then notify the VF. If VF is resetting at that time, the
notify may be dropped, so VF should query it after reset finished.

Currently, Port base vlan is initiated by PF and configured to its VFs,
by using command "ip link set <pf name> vf <vf id> vlan <vlan id>".
When a global reset was triggered, the hardware vlan table and the soft
recorded vlan information will be cleared by PF, and restored them until
VFs were ready. There is a short time window between the table had been
cleared and before table restored. If configured a new port base vlan tag
at this moment, driver will check the soft recorded vlan information,
and find there hasn't the old tag in it, which causing a warning print.
Due to the port base vlan is managed by PF, so the VFs's port base vlan
restoring should be handled by PF when PF was ready.
This patch fixes it.

If the MAC address A is configured to vport A and then vport B. The MAC
address of vport A in the hardware becomes invalid. If the address of
vport A is changed to MAC address B, the driver needs to delete the MAC
address A of vport A. Due to the MAC address A of vport A has become
invalid in the hardware entry, so "-ENOENT" is returned. In this case, the
"used_umv_size" value recorded in driver is not updated. As a result, the
MAC entry status of the software is inconsistent with that of the hardware.
Therefore, the driver updates the umv size even if the MAC entry cannot be
found. Ensure that the software and hardware status is consistent.

is_xen_pmu() is taking the cpu number as parameter, but it is not using
it. Instead it just tests whether the Xen PMU initialization on the
current cpu did succeed. As this test is done by checking a percpu

the cpu while doing the test. While resuming from suspend() this seems
not to be the case:

If a xen domain with at least two VCPUs has a PCI device attached which
enters the D3hot state during suspend, the kernel may hang while
resuming, depending on the core on which an async resume task gets
scheduled.
The bug occurs because xen's do_suspend calls dpm_resume_start while
only the timer of the boot CPU has been resumed (when xen_suspend called
syscore_resume), before calling xen_arch_suspend to resume the timers of
the other CPUs. This breaks pci_dev_d3_sleep.
Thus this patch moves the call to xen_arch_resume before the call to
dpm_resume_start, eliminating the hangs and restoring the stack-like
structure of the suspend/restore procedure.

only bail out when no pages could be faulted in.
We already factor in that pages that are faulted in may no longer be
resident by the time they are accessed. Paging out pages has the same
effect as not faulting in those pages in the first place, so the code
can already deal with that.

Instead of having each time that wants to use ksft_exit() have to figure
out the internals of kselftest.h, add the helper ksft_finished() that
makes sure the passes, xfails, and skips are equal to the test plan count.
