[PATCH AUTOSEL 5.4 1/9] virtio_mmio: Add missing PM calls to freeze/restore

[PATCH AUTOSEL 5.4 1/9] virtio_mmio: Add missing PM calls to freeze/restore

[Sasha Levin]

From: Stephan Gerhold <stephan.gerhold@kernkonzept.com>

[ Upstream commit ed7ac37fde33ccd84e4bd2b9363c191f925364c7 ]

Most virtio drivers provide freeze/restore callbacks to finish up
device usage before suspend and to reinitialize the virtio device after
resume. However, these callbacks are currently only called when using
virtio_pci. virtio_mmio does not have any PM ops defined.

This causes problems for example after suspend to disk (hibernation),
since the virtio devices might lose their state after the VMM is
restarted. Calling virtio_device_freeze()/restore() ensures that
the virtio devices are re-initialized correctly.

Fix this by implementing the dev_pm_ops for virtio_mmio,
similar to virtio_pci_common.

[PATCH AUTOSEL 5.4 2/9] virtio_mmio: Restore guest page size on resume

[Sasha Levin]

From: Stephan Gerhold <stephan.gerhold@kernkonzept.com>

[ Upstream commit e0c2ce8217955537dd5434baeba061f209797119 ]

Virtio devices might lose their state when the VMM is restarted
after a suspend to disk (hibernation) cycle. This means that the
guest page size register must be restored for the virtio_mmio legacy
interface, since otherwise the virtio queues are not functional.

This is particularly problematic for QEMU that currently still defaults
to using the legacy interface for virtio_mmio. Write the guest page
size register again in virtio_mmio_restore() to make legacy virtio_mmio
devices work correctly after hibernation.

[PATCH AUTOSEL 5.4 3/9] netfilter: br_netfilter: do not skip all hooks with 0 priority

[Sasha Levin]

From: Florian Westphal <fw@strlen.de>

[ Upstream commit c2577862eeb0be94f151f2f1fff662b028061b00 ]

When br_netfilter module is loaded, skbs may be diverted to the
ipv4/ipv6 hooks, just like as if we were routing.

Unfortunately, bridge filter hooks with priority 0 may be skipped
in this case.

Example:
1. an nftables bridge ruleset is loaded, with a prerouting
   hook that has priority 0.
2. interface is added to the bridge.
3. no tcp packet is ever seen by the bridge prerouting hook.
4. flush the ruleset
5. load the bridge ruleset again.
6. tcp packets are processed as expected.

After 1) the only registered hook is the bridge prerouting hook, but its
not called yet because the bridge hasn't been brought up yet.

After 2), hook order is:
   0 br_nf_pre_routing // br_netfilter internal hook
   0 chain bridge f prerouting // nftables bridge ruleset

The packet is diverted to br_nf_pre_routing.
If call-iptables is off, the nftables bridge ruleset is called as expected.

But if its enabled, br_nf_hook_thresh() will skip it because it assumes
that all 0-priority hooks had been called previously in bridge context.

To avoid this, check for the br_nf_pre_routing hook itself, we need to
resume directly after it, even if this hook has a priority of 0.

Unfortunately, this still results in different packet flow.
With this fix, the eval order after in 3) is:
1. br_nf_pre_routing
2. ip(6)tables (if enabled)
3. nftables bridge

but after 5 its the much saner:
1. nftables bridge
2. br_nf_pre_routing
3. ip(6)tables (if enabled)

Unfortunately I don't see a solution here:
It would be possible to move br_nf_pre_routing to a higher priority
so that it will be called later in the pipeline, but this also impacts
ebtables evaluation order, and would still result in this very ordering
problem for all nftables-bridge hooks with the same priority as the
br_nf_pre_routing one.

Searching back through the git history I don't think this has
ever behaved in any other way, hence, no fixes-tag.

We encountered a problem that the disconnect command hangs.
After analyzing the log and stack, we found that the triggering
process is as follows:

                                nvme_rdma_error_recovery_work

nvme_do_delete_ctrl                 nvme_stop_queues
  nvme_remove_namespaces
  --clear ctrl->namespaces
                                    nvme_start_queues
                                    --no ns in ctrl->namespaces
    nvme_ns_remove                  return(because ctrl is deleting)
      blk_freeze_queue
        blk_mq_freeze_queue_wait
        --wait for ns to unquiesce to clean infligt IO, hang forever

This problem was not found in older kernels because we will flush
err work in nvme_stop_ctrl before nvme_remove_namespaces.It does not
seem to be modified for functional reasons, the patch can be revert
to solve the problem.

[PATCH AUTOSEL 5.4 9/9] net: sfp: fix memory leak in sfp_probe()

[ Upstream commit 0a18d802d65cf662644fd1d369c86d84a5630652 ]

sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When
devm_add_action() fails, sfp is not freed, which leads to a memory leak.

We should use devm_add_action_or_reset() instead of devm_add_action().
