commit 86a7964be7 upstream.
There is a race between a system call processing thread
and the demultiplex thread when mid->resp_buf becomes NULL
and later is being accessed to get credits. It happens when
the 1st thread wakes up before a mid callback is called in
the 2nd one but the mid state has already been set to
MID_RESPONSE_RECEIVED. This causes NULL pointer dereference
in mid callback.
Fix this by saving credits from the response before we
update the mid state and then use this value in the mid
callback rather then accessing a response buffer.

commit 7b71843fa7 upstream.
When an OPEN command is cancelled we mark a mid as
cancelled and let the demultiplex thread process it
by closing an open handle. The problem is there is
a race between a system call thread and the demultiplex
thread and there may be a situation when the mid has
been already processed before it is set as cancelled.
Fix this by processing cancelled requests when mids
are being destroyed which means that there is only
one thread referencing a particular mid. Also set
mids as cancelled unconditionally on their state.

Currently the client translates O_SYNC and O_DIRECT flags
into corresponding SMB create options when openning a file.
The problem is that on reconnect when the file is being
re-opened the client doesn't set those flags and it causes
a server to reject re-open requests because create options
don't match. The latter means that any subsequent system
call against that open file fail until a share is re-mounted.
Fix this by properly setting SMB create options when
re-openning files after reconnects.

commit e045fa29e8 upstream.
When a driver enables MSI-X, msix_program_entries() reads the MSI-X Vector
Control register for each vector and saves it in desc->masked. Each
register is 32 bits and bit 0 is the actual Mask bit.
When we restored these registers during resume, we previously set the Mask
bit if *any* bit in desc->masked was set instead of when the Mask bit
itself was set:
pci_restore_state
pci_restore_msi_state
__pci_restore_msix_state
for_each_pci_msi_entry
msix_mask_irq(entry, entry->masked) <-- entire u32 word
__pci_msix_desc_mask_irq(desc, flag)
mask_bits = desc->masked & ~PCI_MSIX_ENTRY_CTRL_MASKBIT
if (flag) <-- testing entire u32, not just bit 0
mask_bits |= PCI_MSIX_ENTRY_CTRL_MASKBIT
writel(mask_bits, desc_addr + PCI_MSIX_ENTRY_VECTOR_CTRL)
This means that after resume, MSI-X vectors were masked when they shouldn't
be, which leads to timeouts like this:
nvme nvme0: I/O 978 QID 3 timeout, completion polled
On resume, set the Mask bit only when the saved Mask bit from suspend was
set.
This should remove the need for 19ea025e1d ("nvme: Add quirk for Kingston

pci_pm_thaw_noirq() is supposed to return the device to D0 and restore its
configuration registers, but previously it only did that for devices whose
drivers implemented the new power management ops.
Hibernation, e.g., via "echo disk > /sys/power/state", involves freezing
devices, creating a hibernation image, thawing devices, writing the image,
and powering off. The fact that thawing did not return devices with legacy
power management to D0 caused errors, e.g., in this path:
pci_pm_thaw_noirq
if (pci_has_legacy_pm_support(pci_dev)) # true for Mellanox VF driver
return pci_legacy_resume_early(dev) # ... legacy PM skips the rest
pci_set_power_state(pci_dev, PCI_D0)
pci_restore_state(pci_dev)

if (pci_has_legacy_pm_support(pci_dev))
pci_legacy_resume
drv->resume
mlx4_resume
...
pci_enable_msix_range
...
if (dev->current_state != PCI_D0) # <---
return -EINVAL;
which caused these warnings:
mlx4_core a6d1:00:02.0: INTx is not supported in multi-function mode, aborting
PM: dpm_run_callback(): pci_pm_thaw+0x0/0xd7 returns -95

commit 2ac55d5e5e upstream.
It have turned out that it's not a good idea to unconditionally do a power
cycle and then to re-initialize the SDIO card, as currently done through
mmc_hw_reset() -> mmc_sdio_hw_reset(). This because there may be multiple
SDIO func drivers probed, who also shares the same SDIO card.
To address these scenarios, one may be tempted to use a notification
mechanism, as to allow the core to inform each of the probed func drivers,
about an ongoing HW reset. However, supporting such an operation from the
func driver point of view, may not be entirely trivial.
Therefore, let's use a more simplistic approach to solve the problem, by
instead forcing the card to be removed and re-detected, via scheduling a
rescan-work. In this way, we can rely on existing infrastructure, as the
func driver's ->remove() and ->probe() callbacks, becomes invoked to deal
with the cleanup and the re-initialization.
This solution may be considered as rather heavy, especially if a func
driver doesn't share its card with other func drivers. To address this,
let's keep the current immediate HW reset option as well, but run it only
when there is one func driver probed for the card.
Finally, to allow the caller of mmc_hw_reset(), to understand if the reset
is being asynchronously managed from a scheduled work, it returns 1
(propagated from mmc_sdio_hw_reset()). If the HW reset is executed
successfully and synchronously it returns 0, which maintains the existing
behaviour.

For this reason, let' drop the check for mmc_card_is_removable() as it's

Make the page pool responsible for its own delayed destruction
instead of relying on XDP, so the page pool can be used without
the xdp memory model.
When all pages are returned, free the pool and notify xdp if the
pool is registered with the xdp memory system. Have the callback
perform a table walk since some drivers (cpsw) may share the pool
among multiple xdp_rxq_info.
Note that the increment of pages_state_release_cnt may result in
