[ Upstream commit b4f1874c62168159fdb419ced4afc77c1b51c475 ]
This fixes the boot issues since 5.3 on several Dell models when the TPM
is enabled. Depending on the exact grub binary, booting the kernel would
freeze early, or just report an error parsing the final events log.
We get an event log in the SHA-1 format, which doesn't have a
tcg_efi_specid_event_head in the first event, and there is a final events
table which doesn't match the crypto agile format.
__calc_tpm2_event_size reads bad "count" and "efispecid->num_algs", and
either fails, or loops long enough for the machine to be appear frozen.
So we now only parse the final events table, which is per the spec always
supposed to be in the crypto agile format, when we got a event log in this
format.
Fixes: c46f3405692de ("tpm: Reserve the TPM final events table")
Fixes: 166a2809d65b2 ("tpm: Don't duplicate events from the final event log in the TCG2 log")

[ Upstream commit b455d06e6fb3c035711e8aab1ca18082ccb15d87 ]
DMA channel request should use device struct from platform device struct.
Currently it's using iio device struct. But at this stage when probing,
device struct isn't yet registered (e.g. device_register is done in
iio_device_register). Since commit 71723a96b8b1 ("dmaengine: Create
symlinks between DMA channels and slaves"), a warning message is printed
as the links in sysfs can't be created, due to device isn't yet registered:
- Cannot create DMA slave symlink
- Cannot create DMA dma:rx symlink
Fix this by using device struct from platform device to request dma chan.

dma_request_slave_channel()
[ Upstream commit a9ab624edd9186fbad734cfe5d606a6da3ca34db ]
dma_request_slave_channel() is a wrapper on top of dma_request_chan()
eating up the error code.
By using dma_request_chan() directly the driver can support deferred
probing against DMA.

commit ffca476a0a8d26de767cc41d62b8ca7f540ecfdd upstream.
In the case of get_user_pages_fast() returning fewer pages than
requested, rio_dma_transfer() does not quite do the right thing. It
attempts to release all the pages that were requested, rather than just
the pages that were pinned.
Fix the error handling so that only the pages that were successfully
pinned are released.

commit 60858c00e5f018eda711a3aa84cf62214ef62d61 upstream.
Assume we have kmem configured and loaded:
[root@localhost ~]# cat /proc/iomem
...
140000000-33fffffff : Persistent Memory$
140000000-1481fffff : namespace0.0
150000000-33fffffff : dax0.0
150000000-33fffffff : System RAM
Assume we try to unload kmem. This force-unloading will work, even if
memory cannot get removed from the system.
[root@localhost ~]# rmmod kmem
[ 86.380228] removing memory fails, because memory [0x0000000150000000-0x0000000157ffffff] is onlined
...
[ 86.431225] kmem dax0.0: DAX region [mem 0x150000000-0x33fffffff] cannot be hotremoved until the next reboot
Now, we can reconfigure the namespace:
[root@localhost ~]# ndctl create-namespace --force --reconfig=namespace0.0 --mode=devdax
[ 131.409351] nd_pmem namespace0.0: could not reserve region [mem 0x140000000-0x33fffffff]dax
[ 131.410147] nd_pmem: probe of namespace0.0 failed with error -16namespace0.0 --mode=devdax
...
This fails as expected due to the busy memory resource, and the memory
cannot be used. However, the dax0.0 device is removed, and along its
name.
The name of the memory resource now points at freed memory (name of the
device):
[root@localhost ~]# cat /proc/iomem
...
140000000-33fffffff : Persistent Memory
140000000-1481fffff : namespace0.0
150000000-33fffffff : �_�^7_��/_��wR��WQ���^��� ...
150000000-33fffffff : System RAM
We have to make sure to duplicate the string. While at it, remove the
superfluous setting of the name and fixup a stale comment.

commit 7a839dbab1be59f5ed3b3b046de29e166784c9b4 upstream.
DMA transfers to and from the SD card stall for 10 seconds and run into
timeout on RTS5260 card readers after ASPM was enabled.
Adding a short msleep after disabling ASPM fixes the issue on several
Dell Precision 7530/7540 systems I tested.
This function is only called when waking up after the chip went into
power-save after not transferring data for a few seconds. The added
msleep does therefore not change anything in data transfer speed or
induce any excessive waiting while data transfers are running, or the
chip is sleeping. Only the transition from sleep to active is affected.

commit bcfa1e253d2e329e1ebab5c89f3c73f6dd17606c upstream.
During initial submission the selection of the channel was done using
the scan_index member of the iio_chan_spec structure. It was an abuse
because this member is supposed to be used with a buffer so it was
removed.
However there was still the need to be able to known how to select a
channel, the correct member to store this information is address.
Thanks to this it is possible to select any other channel than the
channel 0.

In the "gb_tty_set_termios" function the "newline" variable is declared
but not initialized. So the "flow_control" member is not initialized and
the OR / AND operations with itself results in an undefined value in
this member.
The purpose of the code is to set the flow control type, so remove the
OR / AND self operator and set the value directly.

commit 5e4f99a6b788047b0b8a7496c2e0c8f372f6edf2 upstream.
If the serial interface is used, the 8-bit address should be latched using
the rising edge of the WR/FSYNC signal.
This basically means that a CS change is required between the first byte
sent, and the second one.
This change splits the single-transfer transfer of 2 bytes into 2 transfers
with a single byte, and CS change in-between.
Note fixes tag is not accurate, but reflects a point beyond which there
are too many refactors to make backporting straight forward.

before attempting to call 'spin_lock_irqsave()' in 'owl_dma_get_pchan()'.
However, according to Manivannan Sadhasivam, 'pchan->lock' was supposed
to only protect 'pchan->vchan' while 'od->lock' does a similar job in
'owl_dma_terminate_pchan()'.
Therefore, this patch substitutes 'pchan->lock' with 'od->lock' and
removes the 'lock' attribute in 'owl_dma_pchan' struct.

commit 40b697e256ccdb88aaff424b44b4d300eb8460e8 upstream.
The GC860 has one GPU device which has a 2d and 3d core. In this case
we want to expose perfmon information for both cores.
The driver has one array which contains all possible perfmon domains
with some meta data - doms_meta. Here we can see that for the GC860
two elements of that array are relevant:
doms_3d: is at index 0 in the doms_meta array with 8 perfmon domains
doms_2d: is at index 1 in the doms_meta array with 1 perfmon domain
The userspace driver wants to get a list of all perfmon domains and
their perfmon signals. This is done by iterating over all domains and
their signals. If the userspace driver wants to access the domain with
id 8 the kernel driver fails and returns invalid data from doms_3d with
and invalid offset.
This results in:
Unable to handle kernel paging request at virtual address 00000000
On such a device it is not possible to use the userspace driver at all.
The fix for this off-by-one error is quite simple.

commit f2e6b75f6ee82308ef7b00f29e71e5f1c6b3d52a upstream.
Testing with Loopback I found that, after a Loopback LUN has executed a
TMR, I can no longer unlink the LUN. The rm command hangs in
transport_clear_lun_ref() at wait_for_completion(&lun->lun_shutdown_comp)
The reason is, that transport_lun_remove_cmd() is not called at the end of
target_tmr_work().
It seems, that in other fabrics this call happens implicitly when the
fabric drivers call transport_generic_free_cmd() during their
->queue_tm_rsp().
Unfortunately Loopback seems to not comply to the common way
of calling transport_generic_free_cmd() from ->queue_*().
Instead it calls transport_generic_free_cmd() from its
->check_stop_free() only.
But the ->check_stop_free() is called by
transport_cmd_check_stop_to_fabric() after it has reset the se_cmd->se_lun
pointer. Therefore the following transport_generic_free_cmd() skips the
transport_lun_remove_cmd().
So this patch re-adds the transport_lun_remove_cmd() at the end of
target_tmr_work(), which was removed during commit 2c9fa49e100f ("scsi:
target/core: Make ABORT and LUN RESET handling synchronous").
For fabrics using transport_generic_free_cmd() in the usual way the double
call to transport_lun_remove_cmd() doesn't harm, as
transport_lun_remove_cmd() checks for this situation and does not release
lun_ref twice.

Calling ql_log() inside qla2x00_port_speed_show() is causing messages to be
output to the console for no particularly good reason. The sysfs read
routine should just return the information to userspace. The only reason
to log a message is when the port speed actually changes, and this already
occurs elsewhere.

[ Upstream commit 3bd12da7f50b8bc191fcb3bab1f55c582234df59 ]
asus-nb-wmi does not add any extra functionality on these Asus
Transformer books. They have detachable keyboards, so the hotkeys are
send through a HID device (and handled by the hid-asus driver) and also
the rfkill functionality is not used on these devices.
Besides not adding any extra functionality, initializing the WMI interface
on these devices actually has a negative side-effect. For some reason
the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives
GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED,
high and there is no (WMI or other) interface to drive this low again
causing the LED to be permanently on, even during suspend.
This commit adds a blacklist of DMI system_ids on which not to load the
asus-nb-wmi and adds these Transformer books to this list. This fixes
the webcam LED being permanently on under Linux.

[ Upstream commit ac854131d9844f79e2fdcef67a7707227538d78a ]
The syzbot fuzzer found a race between URB submission to endpoint 0
and device reset. Namely, during the reset we call usb_ep0_reinit()
because the characteristics of ep0 may have changed (if the reset
follows a firmware update, for example). While usb_ep0_reinit() is
running there is a brief period during which the pointers stored in
udev->ep_in[0] and udev->ep_out[0] are set to NULL, and if an URB is
submitted to ep0 during that period, usb_urb_ep_type_check() will
report it as a driver bug. In the absence of those pointers, the
routine thinks that the endpoint doesn't exist. The log message looks
like this:
------------[ cut here ]------------
usb 2-1: BOGUS urb xfer, pipe 2 != type 2
WARNING: CPU: 0 PID: 9241 at drivers/usb/core/urb.c:478
usb_submit_urb+0x1188/0x1460 drivers/usb/core/urb.c:478
Now, although submitting an URB while the device is being reset is a
questionable thing to do, it shouldn't count as a driver bug as severe
as submitting an URB for an endpoint that doesn't exist. Indeed,
endpoint 0 always exists, even while the device is in its unconfigured
state.
To prevent these misleading driver bug reports, this patch updates
usb_disable_endpoint() to avoid clearing the ep_in[] and ep_out[]
pointers when the endpoint being disabled is ep0. There's no danger
of leaving a stale pointer in place, because the usb_host_endpoint
structure being pointed to is stored permanently in udev->ep0; it
doesn't get deallocated until the entire usb_device structure does.

because the dev pointer is used before the actual check which leads

[ Upstream commit f9c6cea0b38518741c8dcf26ac056d26ee2fd61d ]
During MTU change, the following events may happen.
Client-driven CRQ initialization fails due to partner’s CRQ closed,
causing client to enqueue a reset task for FATAL_ERROR. Then passive
(server-driven) CRQ initialization succeeds, causing client to
release CRQ and enqueue a reset task for failover. If the passive
CRQ initialization occurs before the FATAL reset task is processed,
the FATAL error reset task would try to access a CRQ message queue
that was freed, causing an oops. The problem may be most likely to
occur during DLPAR add vNIC with a non-default MTU, because the DLPAR
process will automatically issue a change MTU request.
Fix this by not processing fatal error reset if CRQ is passively
initialized after client-driven CRQ initialization fails.

[ Upstream commit c48f849d3f7a4ec1025105f446e29d395c4dcc2f ]
Delete all sessions before unregistering local nvme port. This allows nvme
layer to decrement all active rport count down to zero. Once the count is
down to zero, nvme would call qla to continue with the npiv port deletion.

[ Upstream commit 45a76264c26fd8cfd0c9746196892d9b7e2657ee ]
In NPIV environment, a NPIV host may use a queue pair created by base host
or other NPIVs, so the check for a queue pair created by this NPIV is not
correct, and can cause an abort to fail, which in turn means the NVME
command not returned. This leads to hang in nvme_fc layer in
nvme_fc_delete_association() which waits for all I/Os to be returned, which
is seen as hang in the application.

[ Upstream commit 7b01b7239d0dc9832e0d0d23605c1ff047422a2c ]
When the nvmem framework is enabled, a nvmem device is created per mtd
device/partition.
It is not uncommon that a device can have multiple mtd devices with
partitions that have the same name. Eg, when there DT overlay is allowed
and the same device with mtd is attached twice.
Under that circumstances, the mtd fails to register due to a name
duplication on the nvmem framework.
With this patch we use the mtdX name instead of the partition name,
which is unique.
