Pull bcachefs fixes from Kent Overstreet:
- Some fixes to help with filesystem analysis: ensure superblock
error count gets written if we go ERO, don't discard the journal
aggressively (so it's available for list_journal -a)
- Fix lost wakeup on arm causing us to get stuck when reading btree
nodes
- Fix fsck failing to exit on ctrl-c
- An additional fix for filesystems with misaligned bucket sizes: we
now ensure that allocations are properly aligned
- Setting background target but not promote target will now leave that
data cached on the foreground target, as it used to
- Revert a change to when we allocate the VFS superblock, this was done
for implementing blk_holder_ops but ended up not being needed, and
allocating a superblock and not setting SB_BORN while we do recovery
caused sync() calls and other things to hang
- Assorted fixes for harmless error messages that caused concern to
users

Pull vfio fix from Alex Williamson:
- Fix an issue in vfio-pci huge_fault handling by aligning faults to
the order, resulting in deterministic use of huge pages. This
avoids a race where simultaneous aligned and unaligned faults to
the same PMD can result in a VM_FAULT_OOM and subsequent VM crash.

NIPA tests report that the interface statistics reported
via qstat are lower than those reported via ip link.
Looks like this is because some tests flip the queue

Older drivers and drivers with lower queue counts often have a static
array of queues, rather than allocating structs for each queue on demand.
Add a helper for adding up qstats from a queue range. Expectation is
that driver will pass a queue range [netdev->real_num_*x_queues, MAX).
It was tempting to always use num_*x_queues as the end, but virtio
seems to clamp its queue count after allocating the netdev. And this
way we can trivaly reuse the helper for [0, real_..).

====================
fbnic: FW IPC Mailbox fixes
This series is meant to address a number of issues that have been found in
the FW IPC mailbox over the past several months.
The main issues addressed are:
1. Resolve a potential race between host and FW during initialization that
can cause the FW to only have the lower 32b of an address.
2. Block the FW from issuing DMA requests after we have closed the mailbox
and before we have started issuing requests on it.
3. Fix races in the IRQ handlers that can cause the IRQ to unmask itself if
it is being processed while we are trying to disable it.
4. Cleanup the Tx flush logic so that we actually lock down the Tx path
before we start flushing it instead of letting it free run while we are
shutting it down.
5. Fix several memory leaks that could occur if we failed initialization.
6. Cleanup the mailbox completion if we are flushing Tx since we are no
longer processing Rx.
7. Move several allocations out of a potential IRQ/atomic context.
There have been a few optimizations we also picked up since then. Rather
than split them out I just folded them into these diffs. They mostly
address minor issues such as how long it takes to initialize and/or fail so
I thought they could probably go in with the rest of the patches. They
consist of:
1. Do not sleep more than 20ms waiting on FW to respond as the 200ms value
likely originated from simulation/emulation testing.
2. Use jiffies to determine timeout instead of sleep * attempts for better
accuracy.

We had originally thought to have the mailbox go to ready in the background
while we were doing other things. One issue with this though is that we
can't disable it by clearing the ready state without also blocking
interrupts or calls to mbx_poll as it will just pop back to life during an
interrupt.
In order to prevent that from happening we can pull the code for toggling
to ready out of the interrupt path and instead place it in the
fbnic_mbx_poll_tx_ready path so that it becomes the only spot where the
Rx/Tx can toggle to the ready state. By doing this we can prevent races
where we disable the DMA and/or free buffers only to have an interrupt fire
and undo what we have done.

This change pulls the call to fbnic_fw_xmit_cap_msg out of
fbnic_mbx_init_desc_ring and instead places it in the polling function for
getting the Tx ready. Doing that we can avoid the potential issue with an

There were a couple different issues found in fbnic_mbx_poll_tx_ready.
Among them were the fact that we were sleeping much longer than we actually
needed to as the actual FW could respond in under 20ms. The other issue was
that we would just keep polling the mailbox even if the device itself had
gone away.
To address the responsiveness issues we can decrease the sleeps to 20ms and
use a jiffies based timeout value rather than just counting the number of
times we slept and then polled.
To address the hardware going away we can move the check for the firmware
BAR being present from where it was and place it inside the loop after the
mailbox descriptor ring is initialized and before we sleep so that we just
abort and return an error if the device went away during initialization.
With these two changes we see a significant improvement in boot times for
the driver.

There was an issue in that if we were to shutdown we could be left with
a completion in flight as the mailbox went away. To address that I have
added an fbnic_mbx_evict_all_cmpl function that is meant to essentially
create a "broken pipe" type response so that all callers will receive an
error indicating that the connection has been broken as a result of us
shutting down the mailbox.

The fbnic_mbx_flush_tx function had a number of issues.
First, we were waiting 200ms for the firmware to process the packets. We
can drop this to 20ms and in almost all cases this should be more than
enough time. So by changing this we can significantly reduce shutdown time.
Second, we were not making sure that the Tx path was actually shut off. As
such we could still have packets added while we were flushing the mailbox.
To prevent that we can now clear the ready flag for the Tx side and it
should stay down since the interrupt is disabled.
Third, we kept re-reading the tail due to the second issue. The tail should
not move after we have started the flush so we can just read it once while
we are holding the mailbox Tx lock. By doing that we are guaranteed that
the value should be consistent.
Fourth, we were keeping a count of descriptors cleaned due to the second
and third issues called out. That count is not a valid reason to be exiting
the cleanup, and with the tail only being read once we shouldn't see any
cases where the tail moves after the disable so the tracking of count can
be dropped.
Fifth, we were using attempts * sleep time to determine how long we would
wait in our polling loop to flush out the Tx. This can be very imprecise.
In order to tighten up the timing we are shifting over to using a jiffies
value of jiffies + 10 * HZ + 1 to determine the jiffies value we should
stop polling at as this should be accurate within once sleep cycle for the
total amount of time spent polling.

We have two issues that need to be addressed in our IRQ handling.
One is the fact that we can end up double-freeing IRQs in the event of an
exception handling error such as a PCIe reset/recovery that fails. To
prevent that from becoming an issue we can use the msix_vector values to
indicate that we have successfully requested/freed the IRQ by only setting
or clearing them when we have completed the given action.
The other issue is that we have several potential races in our IRQ path due
to us manipulating the mask before the vector has been truly disabled. In
order to handle that in the case of the FW mailbox we need to not
auto-enable the IRQ and instead will be enabling/disabling it separately.
In the case of the PCS vector we can mitigate this by unmapping it and
synchronizing the IRQ before we clear the mask.
The general order of operations after this change is now to request the
interrupt, poll the FW mailbox to ready, and then enable the interrupt. For
the shutdown we do the reverse where we disable the interrupt, flush any
pending Tx, and then free the IRQ. I am renaming the enable/disable to
request/free to be equivilent with the IRQ calls being used. We may see
additions in the future to enable/disable the IRQs versus request/free them
for certain use cases.

In order to prevent the device from throwing spurious writes and/or reads
at us we need to gate the AXI fabric interface to the PCIe until such time
as we know the FW is in a known good state.
To accomplish this we use the mailbox as a mechanism for us to recognize
that the FW has acknowledged our presence and is no longer sending any
stale message data to us.
We start in fbnic_mbx_init by calling fbnic_mbx_reset_desc_ring function,
disabling the DMA in both directions, and then invalidating all the
descriptors in each ring.
We then poll the mailbox in fbnic_mbx_poll_tx_ready and when the interrupt
is set by the FW we pick it up and mark the mailboxes as ready, while also
enabling the DMA.
Once we have completed all the transactions and need to shut down we call
into fbnic_mbx_clean which will in turn call fbnic_mbx_reset_desc_ring for
each ring and shut down the DMA and once again invalidate the descriptors.

Address to issues with the FW mailbox descriptor initialization.
We need to reverse the order of accesses when we invalidate an entry versus
writing an entry. When writing an entry we write upper and then lower as
the lower 32b contain the valid bit that makes the entire address valid.
However for invalidation we should write it in the reverse order so that
the upper is marked invalid before we update it.
Without this change we may see FW attempt to access pages with the upper
32b of the address set to 0 which will likely result in DMAR faults due to
write access failures on mailbox shutdown.

====================
net: dsa: b53: accumulated fixes
This patchset aims at fixing most issues observed while running the
vlan_unaware_bridge, vlan_aware_bridge and local_termination selftests.
Most tests succeed with these patches on BCM53115, connected to a
BCM6368.
It took me a while to figure out that a lot of tests will fail if all
ports have the same MAC address, as the switches drop any frames with
DA == SA. Luckily BCM63XX boards often have enough MACs allocated for
all ports, so I just needed to assign them.
The still failing tests are:
FDB learning, both vlan aware aware and unaware:
This is expected, as b53 currently does not implement changing the
ageing time, and both the bridge code and DSA ignore that, so the
learned entries don't age out as expected.
ping and ping6 in vlan unaware:
These fail because of the now fixed learning, the switch trying to
forward packet ingressing on one of the standalone ports to the learned
port of the mac address when the packets ingressed on the bridged port.
The port VLAN masks only prevent forwarding to other ports, but the ARL
lookup will still happen, and the packet gets dropped because the port
isn't allowed to forward there.
I have a fix/workaround for that, but as it is a bit more controversial
and makes use of an unrelated feature, I decided to hold off from that
and post it later.
This wasn't noticed so far, because learning was never working in VLAN
unaware mode, so the traffic was always broadcast (which sidesteps the
issue).
Finally some of the multicast tests from local_termination fail, where
the reception worked except it shouldn't. This doesn't seem to me as a
super serious issue, so I didn't attempt to debug/fix these yet.
I'm not super confident I didn't break sf2 along the way, but I did
compile test and tried to find ways it cause issues (I failed to find
any). I hope Florian will tell me.

When a port gets set up, b53 disables learning and enables the port for
flooding. This can undo any bridge configuration on the port.
E.g. the following flow would disable learning on a port:
$ ip link add br0 type bridge
$ ip link set sw1p1 master br0 <- enables learning for sw1p1
$ ip link set br0 up
$ ip link set sw1p1 up <- disables learning again
Fix this by populating dsa_switch_ops::port_setup(), and set up initial
config there.

To allow runtime switching between vlan aware and vlan non-aware mode,
we need to properly keep track of any bridge VLAN configuration.
Likewise, we need to know when we actually switch between both modes, to
not have to rewrite the full VLAN table every time we update the VLANs.
So keep track of the current vlan_filtering mode, and on changes, apply

Since we cannot set forwarding destinations per VLAN, we should not have
a VLAN 0 configured, as it would allow untagged traffic to work across
ports on VLAN aware bridges regardless if a PVID untagged VLAN exists.
So remove the VLAN 0 on join, an re-add it on leave. But only do so if
we have a VLAN aware bridge, as without it, untagged traffic would
become tagged with VID 0 on a VLAN unaware bridge.

Fix this to use the correct VLAN entry for the default pvid.

Currently the PVID of ports are only set when adding/updating VLANs with
PVID set or removing VLANs, but not when clearing the PVID flag of a
VLAN.
E.g. the following flow
$ ip link add br0 type bridge vlan_filtering 1
$ ip link set sw1p1 master bridge
$ bridge vlan add dev sw1p1 vid 10 pvid untagged
$ bridge vlan add dev sw1p1 vid 10 untagged
Would keep the PVID set as 10, despite the flag being cleared. Fix this
by checking if we need to unset the PVID on vlan updates.

The Broadcom management header does not carry the original VLAN tag
state information, just the ingress port, so for untagged frames we do
not know from which VLAN they originated.
Therefore keep the CPU port always tagged except for VLAN 0.
Fixes the following setup:
$ ip link add br0 type bridge vlan_filtering 1
$ ip link set sw1p1 master br0
$ bridge vlan add dev br0 pvid untagged self
$ ip link add sw1p2.10 link sw1p2 type vlan id 10
Where VID 10 would stay untagged on the CPU port.

When sending out any kind of traffic, it is essential that the driver
keeps reporting BQL of the number of bytes that have been sent so that
BQL can track the amount of data in the queue and prevents it from
overflowing. If BQL is not reported, the driver may continue sending
packets even when the queue is full, leading to packet loss, congestion
and decreased network performance. Currently this is missing in
emac_xmit_xdp_frame() and this patch fixes it.

Add __netif_tx_lock() to ensure that only one packet is being
transmitted at a time to avoid race conditions in the netif_txq
struct and prevent packet data corruption. Failing to do so causes
kernel panic with the following error:

When bpf_redirect_peer is used to redirect packets to a device in
another network namespace, the skb isn't scrubbed. That can lead skb
information from one namespace to be "misused" in another namespace.
As one example, this is causing Cilium to drop traffic when using
bpf_redirect_peer to redirect packets that just went through IPsec
decryption to a container namespace. The following pwru trace shows (1)
the packet path from the host's XFRM layer to the container's XFRM
layer where it's dropped and (2) the number of active skb extensions at
each function.

.active_extensions = (__u8)2,
In this case, there are no XFRM policies in the container's network
namespace so the drop is unexpected. When we decrypt the IPsec packet,
the XFRM state used for decryption is set in the skb extensions. This
information is preserved across the netns switch. When we reach the
XFRM policy check in the container's netns, __xfrm_policy_check drops
the packet with LINUX_MIB_XFRMINNOPOLS because a (container-side) XFRM
policy can't be found that matches the (host-side) XFRM state used for
decryption.
This patch fixes this by scrubbing the packet when using
bpf_redirect_peer, as is done on typical netns switches via veth
devices except skb->mark and skb->tstamp are not zeroed.

The official Airoha EN7581 firmware requires adding max_packet field in
ppe_mbox_data struct while the unofficial one used to develop the Airoha
EN7581 flowtable support does not require this field.
This patch does not introduce any real backwards compatible issue since
EN7581 fw is not publicly available in linux-firmware or other
repositories (e.g. OpenWrt) yet and the official fw version will use this
new layout. For this reason this change needs to be backported.
Moreover, make explicit the padding added by the compiler introducing
the rsv array in init_info struct.
At the same time use u32 instead of int for init_info and set_info
struct definitions in ppe_mbox_data struct.

Region locking introduced in v5.6-rc4 contained three macros to handle
the region locks: ahash_bucket_start(), ahash_bucket_end() which gave
back the start and end hash bucket values belonging to a given region
lock and ahash_region() which should give back the region lock belonging
to a given hash bucket. The latter was incorrect which can lead to a
race condition between the garbage collector and adding new elements
when a hash type of set is defined with timeouts.

syzbot reports for uninit-value for the saddr argument [1].
commit 4754957f04f5 ("ipvs: do not use random local source address for

should be ignored but the code is still reading it which can prevent
to connect the route. Fix it by changing the argument to ret_saddr.

We frequently use 'bcachefs list_journal -a' for debugging, as it
provides a record of all btree transactions, and a history of what
happened.
But it's not so useful if we immediately discard journal buckets right
after they're no longer dirty.
This tweaks journal reclaim to only discard when we're low on space,
keeping the journal mostly un-discarded.

With commit bcb5d6c76903 ("s390/pci: introduce lock to synchronize state
of zpci_dev's") the code to ignore power off of a PF that has child VFs
was changed from a direct return to a goto to the unlock and
pci_dev_put() section. The change however left the existing pci_dev_put()
untouched resulting in a doubple put. This can subsequently cause a use
after free if the struct pci_dev is released in an unexpected state.
Fix this by removing the extra pci_dev_put().

The zpci_create_device() function returns an error pointer that needs to
be checked before dereferencing it as a struct zpci_dev pointer. Add the
missing check in __clp_add() where it was missed when adding the
scan_list in the fixed commit. Simply not adding the device to the scan
list results in the previous behavior.
