smb: client: fix null auth

BugLink: https://bugs.launchpad.net/bugs/2036450

Commit abdb1742a312 removed code that clears ctx->username when sec=none, so attempting
to mount with '-o sec=none' now fails with -EACCES. Fix it by adding that logic to the
parsing of the 'sec' option, as well as checking if the mount is using null auth before
setting the username when parsing the 'user' option.

Fixes: abdb1742a312 ("cifs: get rid of mount options string parsing")

PCI: hv: Use async probing to reduce boot time

BugLink: https://bugs.launchpad.net/bugs/2023071
BugLink: https://bugs.launchpad.net/bugs/2023594

Commit 414428c5da1c ("PCI: hv: Lock PCI bus on device eject") added
pci_lock_rescan_remove() and pci_unlock_rescan_remove() in
create_root_hv_pci_bus() and in hv_eject_device_work() to address the
race between create_root_hv_pci_bus() and hv_eject_device_work(), but it
turns that grabing the pci_rescan_remove_lock mutex is not enough:
refer to the earlier fix "PCI: hv: Add a per-bus mutex state_lock".

Now with hbus->state_lock and other fixes, the race is resolved, so
remove pci_{lock,unlock}_rescan_remove() in create_root_hv_pci_bus():
this removes the serialization in hv_pci_probe() and hence allows
async-probing (PROBE_PREFER_ASYNCHRONOUS) to work.

Add the async-probing flag to hv_pci_drv.

pci_{lock,unlock}_rescan_remove() in hv_eject_device_work() and in
hv_pci_remove() are still kept: according to the comment before
drivers/pci/probe.c: static DEFINE_MUTEX(pci_rescan_remove_lock),
"PCI device removal routines should always be executed under this mutex".

net: mana: Add support for jumbo frame

BugLink: https://bugs.launchpad.net/bugs/2016898

During probe, get the hardware-allowed max MTU by querying the device
configuration. Users can select MTU up to the device limit.
When XDP is in use, limit MTU settings so the buffer size is within
one page. And, when MTU is set to a too large value, XDP is not allowed
to run.
Also, to prevent changing MTU fails, and leaves the NIC in a bad state,
pre-allocate all buffers before starting the change. So in low memory
condition, it will return error, without affecting the NIC.

net: mana: Fix accessing freed irq affinity_hint

BugLink: https://bugs.launchpad.net/bugs/2007417

After calling irq_set_affinity_and_hint(), the cpumask pointer is
saved in desc->affinity_hint, and will be used later when reading
/proc/irq/<num>/affinity_hint. So the cpumask variable needs to be
persistent. Otherwise, we are accessing freed memory when reading
the affinity_hint file.

Also, need to clear affinity_hint before free_irq(), otherwise there
is a one-time warning and stack trace during module unloading:

 [ 243.948687] WARNING: CPU: 10 PID: 1589 at kernel/irq/manage.c:1913 free_irq+0x318/0x360

To fix the bug, use the persistent mask, cpumask_of(cpu#), and set
affinity_hint to NULL before freeing the IRQ, as required by free_irq().

UBUNTU: SAUCE: PCI: hv: Only reuse existing IRTE allocation for Multi-MSI

BugLink: https://bugs.launchpad.net/bugs/1990184

Jeffrey's 4 recent patches added Multi-MSI support to the pci-hyperv driver.
Unluckily, one of the patches, i.e., b4b77778ecc5, causes a regression to a
fio test for the Azure VM SKU Standard L64s v2 (64 AMD vCPUs, 8 NVMe drives):

when fio runs against all the 8 NVMe drives, it runs fine with a low io-depth
(e.g., 2 or 4); when fio runs with a high io-depth (e.g., 256), somehow
queue-29 of each NVMe drive suddenly no longer receives any interrupts, and
the NVMe core code has to abort the queue after a timeout of 30 seconds, and
then queue-29 starts to receive interrupts again for several seconds, and
later queue-29 no longer receives interrupts again, and this pattern repeats:

[ 223.891249] nvme nvme2: I/O 320 QID 29 timeout, aborting
[ 223.896231] nvme nvme0: I/O 320 QID 29 timeout, aborting
[ 223.898340] nvme nvme4: I/O 832 QID 29 timeout, aborting
[ 259.471309] nvme nvme2: I/O 320 QID 29 timeout, aborting
[ 259.476493] nvme nvme0: I/O 321 QID 29 timeout, aborting
[ 259.482967] nvme nvme0: I/O 322 QID 29 timeout, aborting

Some other symptoms are: the throughput of the NVMe drives drops due to
commit b4b77778ecc5. When the fio test is running, the kernel prints some
soft lock-up messages from time to time.

Commit b4b77778ecc5 itself looks good, and at the moment it's unclear where
the issue is. While the issue is being investigated, restore the old behavior
in hv_compose_msi_msg(), i.e., don't reuse the existing IRTE allocation for
single-MSI and MSI-X. This is a stopgap for the above NVMe issue.

cifs: destage any unwritten data to the server before calling copychunk_write

BugLink: https://bugs.launchpad.net/bugs/1970977

because the copychunk_write might cover a region of the file that has not yet
been sent to the server and thus fail.

A simple way to reproduce this is:
truncate -s 0 /mnt/testfile; strace -f -o x -ttT xfs_io -i -f -c 'pwrite 0k 128k' -c 'fcollapse 16k 24k' /mnt/testfile

the issue is that the 'pwrite 0k 128k' becomes rearranged on the wire with
the 'fcollapse 16k 24k' due to write-back caching.

fcollapse is implemented in cifs.ko as a SMB2 IOCTL(COPYCHUNK_WRITE) call
and it will fail serverside since the file is still 0b in size serverside
until the writes have been destaged.
To avoid this we must ensure that we destage any unwritten data to the
server before calling COPYCHUNK_WRITE.
