Pull zonefs fixes from Damien Le Moal:
- Fix the IO error recovery path for failures happening in the last

Fix a deadlock introduced by commit
974578017fc1 ("iavf: Add waiting so the port is initialized in remove")
due to race condition between iavf_shutdown and iavf_remove, where
iavf_remove stucks forever in while loop since iavf_shutdown already
set __IAVF_REMOVE adapter state.
Fix this by checking if the __IAVF_IN_REMOVE_TASK has already been

IAVF_FLAG_INITIAL_MAC_SET prevents waiting on iavf_is_mac_set_handled()
the first time the MAC is set. This breaks gratuitous ARP because the
MAC address has not been updated yet when the gARP packet is sent out.

After commit aa626da947e9 ("iavf: Detach device during reset task")
the device is detached during reset task and re-attached at its end.
The problem occurs when reset task fails because Tx queues are
restarted during device re-attach and this leads later to a crash.
To resolve this issue properly close the net device in cause of
failure in reset task to avoid restarting of tx queues at the end.
Also replace the hacky manipulation with IFF_UP flag by device close
that clears properly both IFF_UP and __LINK_STATE_START flags.
In these case iavf_close() does not do anything because the adapter
state is already __IAVF_DOWN.
Reproducer:
1) Run some Tx traffic (e.g. iperf3) over iavf interface
2) Set VF trusted / untrusted in loop
[root@host ~]# cat repro.sh
PF=enp65s0f0
IF=${PF}v0
ip link set up $IF
ip addr add 192.168.0.2/24 dev $IF
sleep 1

Recent commit aa626da947e9 ("iavf: Detach device during reset task")
removed netif_tx_stop_all_queues() with an assumption that Tx queues
are already stopped by netif_device_detach() in the beginning of
reset task. This assumption is incorrect because during reset
task a potential link event can start Tx queues again.
Revert this change to fix this issue.
Reproducer:
1. Run some Tx traffic (e.g. iperf3) over iavf interface
2. Switch MTU of this interface in a loop

- Fix deadlock in discontiguous saved segments (DCSS) block device
driver. When adding a disk and scanning partitions the scan would not
break out early without a missed flag.
- Avoid using global register variable for current_stack_pointer due to
an old bug in gcc versions prior to gcc-8.4. Due to this bug a broken
code is generated, which leads to stack corruptions.

When we post a CQE we wake all ring pollers as it normally should be.
However, if a CQE was generated by a multishot poll request targeting
its own ring, it'll wake that request up, which will make it to post
a new CQE, which will wake the request and so on until it exhausts all
CQ entries.
Don't allow multishot polling io_uring files but downgrade them to
oneshots, which was always stated as a correct behaviour that the
userspace should check for.

and could not activate it because it had a non-empty journal.
Fix this problem by flushing the journal (done by the previous commit)

This commit flushes the journal on suspend. It is prerequisite for the
next commit that enables activating dm integrity devices in read-only mode.
Note that we deliberately didn't flush the journal on suspend, so that the
journal replay code would be tested. However, the dm-integrity code is 5
years old now, so that journal replay is well-tested, and we can make this
change now.

__list_versions will first estimate the required space using the
"dm_target_iterate(list_version_get_needed, &needed)" call and then will
fill the space using the "dm_target_iterate(list_version_get_info,
&iter_info)" call. Each of these calls locks the targets using the
"down_read(&_lock)" and "up_read(&_lock)" calls, however between the first
and second "dm_target_iterate" there is no lock held and the target
modules can be loaded at this point, so the second "dm_target_iterate"
call may need more space than what was the first "dm_target_iterate"
returned.
The code tries to handle this overflow (see the beginning of
list_version_get_info), however this handling is incorrect.
The code sets "param->data_size = param->data_start + needed" and
"iter_info.end = (char *)vers+len" - "needed" is the size returned by the
first dm_target_iterate call; "len" is the size of the buffer allocated by
userspace.
"len" may be greater than "needed"; in this case, the code will write up
to "len" bytes into the buffer, however param->data_size is set to
"needed", so it may write data past the param->data_size value. The ioctl
interface copies only up to param->data_size into userspace, thus part of
the result will be truncated.
Fix this bug by setting "iter_info.end = (char *)vers + needed;" - this
guarantees that the second "dm_target_iterate" call will write only up to
the "needed" buffer and it will exit with "DM_BUFFER_FULL_FLAG" if it
overflows the "needed" space - in this case, userspace will allocate a
larger buffer and retry.
Note that there is also a bug in list_version_get_needed - we need to add
"strlen(tt->name) + 1" to the needed size, not "strlen(tt->name)".

Elements with an end interval flag set on do not store extensions. The
global set definition is currently setting on the timeout and stateful
expression for end interval elements.

Sony's downstream driver [1], among some other changes, adds a
seemingly random 10ms usleep_range, which turned out to be necessary
for the hardware to function properly on at least Sony Xperia 1 IV.
Without this, I2C transactions with the SLG51000 straight up fail.
Relax (10-10ms -> 10-11ms) and add the aforementioned sleep to make
sure the hardware has some time to wake up.

https://syzkaller.appspot.com/bug?id=6c7cd46c7bdd0e86f95d26ec3153208ad186f9fa
The callstack is different but the issue is valid and re-producable with
the same re-producer in the link.
The root cause of this issue is that we check the size of the message
received against the msize of the client in p9_read_work. However, it
turns out that capacity is no longer consistent with msize. Thus,
the message size should be checked against sdata capacity.
As the msize is non-consistant with the capacity of the tag and as we
are now checking message size against capacity directly, there is no
point checking message size against msize. So remove it.

kernel BUG at lib/list_debug.c:53!
invalid opcode: 0000 [#1] PREEMPT SMP KASAN
RIP: 0010:__list_del_entry_valid.cold+0x5c/0x72

The process is as follows:
Thread A: Thread B:
p9_poll_workfn() p9_client_create()
... ...
p9_conn_cancel() p9_fd_cancel()
list_del() ...
... list_del() //list_del
corruption
There is no lock protection when deleting list in p9_conn_cancel(). After
deleting list in Thread A, thread B will delete the same list again. It
will cause issue of list_del corruption.
Setting req->status to REQ_STATUS_ERROR under lock prevents other
cleanup paths from trying to manipulate req_list.
The other thread can safely check req->status because it still holds a
reference to req at this point.

In pch_gbe_xmit_frame(), NETDEV_TX_OK will be returned whether
pch_gbe_tx_queue() sends data successfully or not, so pch_gbe_tx_queue()
needs to free skb before returning. But pch_gbe_tx_queue() returns without
freeing skb in case of dma_map_single() fails. Add dev_kfree_skb_any()
to fix it.

Previously we leverage NCI_UNREG and the lock inside nci_close_device to
prevent the race condition between opening a device and closing a
device. However, it still has problem because a failed opening command
will erase the NCI_UNREG flag and allow another opening command to
bypass the status checking.
This fix corrects that by making sure the NCI_UNREG is held.

You'd think people know that the internal 100BASE-TX PHY on the SJA1110
responds only to clause 22 MDIO transactions, but they don't :)
When a clause 45 transaction is attempted, sja1105_base_tx_mdio_read()
and sja1105_base_tx_mdio_write() don't expect "reg" to contain bit 30
set (MII_ADDR_C45) and pack this value into the SPI transaction buffer.
But the field in the SPI buffer has a width smaller than 30 bits, so we
see this confusing message from the packing() API rather than a proper
rejection of C45 transactions:

After rxrpc_unbundle_conn() has removed a connection from a bundle, it
checks to see if there are any conns with available channels and, if not,
removes and attempts to destroy the bundle.
Whilst it does check after grabbing client_bundles_lock that there are no
connections attached, this races with rxrpc_look_up_bundle() retrieving the
bundle, but not attaching a connection for the connection to be attached
later.
There is therefore a window in which the bundle can get destroyed before we
manage to attach a new connection to it.
Fix this by adding an "active" counter to struct rxrpc_bundle:
(1) rxrpc_connect_call() obtains an active count by prepping/looking up a
bundle and ditches it before returning.
(2) If, during rxrpc_connect_call(), a connection is added to the bundle,
this obtains an active count, which is held until the connection is
discarded.
(3) rxrpc_deactivate_bundle() is created to drop an active count on a
bundle and destroy it when the active count reaches 0. The active
count is checked inside client_bundles_lock() to prevent a race with
rxrpc_look_up_bundle().
(4) rxrpc_unbundle_conn() then calls rxrpc_deactivate_bundle().

In addition, use the BPF_FILE variable to save the BPF object file name,

The SPI framework checks for each transfer (with the struct
spi_controller::can_dma callback) whether the driver wants to use DMA
for the transfer. If the driver returns true, the SPI framework will
map the transfer's data to the device, start the actual transfer and
map the data back.
In commit 07e759387788 ("spi: spi-imx: add PIO polling support") the
spi-imx driver's spi_imx_transfer_one() function was extended. If the
estimated duration of a transfer does not exceed a configurable
duration, a polling transfer function is used. This check happens
before checking if the driver decided earlier for a DMA transfer.
If spi_imx_can_dma() decided to use a DMA transfer, and the user
configured a big maximum polling duration, a polling transfer will be
used. The DMA unmap after the transfer destroys the transferred data.
To fix this problem check in spi_imx_transfer_one() if the driver
decided for DMA transfer first, then check the limits for a polling
transfer.

Recently syzkaller discovered the issue of disappearing lower
device (NETDEV_UNREGISTER) while the virtual device (like
macvlan) is still having it as a lower device. So it's just
a matter of time similar discovery will be made for IPvlan
device setup. So fixing it preemptively. Also while at it,
add a refcount tracker.

Commit 0ff4eb3d5ebb ("neighbour: make proxy_queue.qlen limit
per-device") introduced the length counter qlen in struct neigh_parms.
There are separate neigh_parms instances for IPv4/ARP and IPv6/ND, and
while the family specific qlen is incremented in pneigh_enqueue(), the
mentioned commit decrements always the IPv4/ARP specific qlen,
regardless of the currently processed family, in pneigh_queue_purge()
and neigh_proxy_process().
As a result, with IPv6/ND, the family specific qlen is only incremented
(and never decremented) until it exceeds PROXY_QLEN, and then, according
to the check in pneigh_enqueue(), neighbor solicitations are not
answered anymore. As an example, this is noted when using the
subnet-router anycast address to access a Linux router. After a certain
amount of time (in the observed case, qlen exceeded PROXY_QLEN after two
days), the Linux router stops answering neighbor solicitations for its
subnet-router anycast address and effectively becomes unreachable.
Another result with IPv6/ND is that the IPv4/ARP specific qlen is
decremented more often than incremented. This leads to negative qlen
values, as a signed integer has been used for the length counter qlen,
and potentially to an integer overflow.
Fix this by introducing the helper function neigh_parms_qlen_dec(),
which decrements the family specific qlen. Thereby, make use of the
existing helper function neigh_get_dev_parms_rcu(), whose definition
therefore needs to be placed earlier in neighbour.c. Take the family
member from struct neigh_table to determine the currently processed
family and appropriately call neigh_parms_qlen_dec() from
pneigh_queue_purge() and neigh_proxy_process().
Additionally, use an unsigned integer for the length counter qlen.
