[ Upstream commit d480e57809a043333a3b9e755c0bdd43e10a9f12 ]
Compilation can fail due to having an inline function reference where the
function body is not present.
Fix by removing the inline tag.

[ Upstream commit fb945c95a482200876993977008b67ea658bd938 ]
While the commit 2b8bd606b1e6 ("mfd: dln2: More sanity checking for endpoints")
tries to harden the sanity checks it made at the same time a regression,
i.e. mixed in and out endpoints. Obviously it should have been not tested on
real hardware at that time, but unluckily it didn't happen.
So, fix above mentioned typo and make device being enumerated again.
While here, introduce an enumerator for magic values to prevent similar issue
to happen in the future.

The DDI IO power well must not be enabled for a TypeC port in TBT mode,
ensure this during driver loading/system resume.
This gets rid of error messages like
[drm] *ERROR* power well DDI E TC2 IO state mismatch (refcount 1/enabled 0)
and avoids leaking the power ref when disabling the output.

[ Upstream commit 8732fe46b20c951493bfc4dba0ad08efdf41de81 ]
The issues caused by:
commit 64e62bdf04ab ("drm/dp_mst: Remove VCPI while disabling topology
mgr")
Prompted me to take a closer look at how we clear the payload state in
general when disabling the topology, and it turns out there's actually
two subtle issues here.
The first is that we're not grabbing &mgr.payload_lock when clearing the
payloads in drm_dp_mst_topology_mgr_set_mst(). Seeing as the canonical
lock order is &mgr.payload_lock -> &mgr.lock (because we always want
&mgr.lock to be the inner-most lock so topology validation always
works), this makes perfect sense. It also means that -technically- there
could be racing between someone calling
drm_dp_mst_topology_mgr_set_mst() to disable the topology, along with a
modeset occurring that's modifying the payload state at the same time.
The second is the more obvious issue that Wayne Lin discovered, that
we're not clearing proposed_payloads when disabling the topology.
I actually can't see any obvious places where the racing caused by the
first issue would break something, and it could be that some of our
higher-level locks already prevent this by happenstance, but better safe
then sorry. So, let's make it so that drm_dp_mst_topology_mgr_set_mst()
first grabs &mgr.payload_lock followed by &mgr.lock so that we never
race when modifying the payload state. Then, we also clear
proposed_payloads to fix the original issue of enabling a new topology
with a dirty payload state. This doesn't clear any of the drm_dp_vcpi
structures, but those are getting destroyed along with the ports anyway.
Changes since v1:
* Use sizeof(mgr->payloads[0])/sizeof(mgr->proposed_vcpis[0]) instead -

[ Upstream commit 835214f5d5f516a38069bc077c879c7da00d6108 ]
When driver is set to enable bb credit recovery, the switch displayed the
setting as inactive. If the link bounces, it switches to Active.
During link up processing, the driver currently does a MBX_READ_SPARAM
followed by a MBX_CONFIG_LINK. These mbox commands are queued to be
executed, one at a time and the completion is processed by the worker
thread. Since the MBX_READ_SPARAM is done BEFORE the MBX_CONFIG_LINK, the
BB_SC_N bit is never set the the returned values. BB Credit recovery status
only gets set after the driver requests the feature in CONFIG_LINK, which
is done after the link up. Thus the ordering of READ_SPARAM needs to follow
the CONFIG_LINK.
Fix by reordering so that READ_SPARAM is done after CONFIG_LINK. Added a
HBA_DEFER_FLOGI flag so that any FLOGI handling waits until after the
READ_SPARAM is done so that the proper BB credit value is set in the FLOGI
payload.

[ Upstream commit 6bfb1620829825c01e1dcdd63b6a7700352babd9 ]
The driver today is reading service parameters from the firmware and then
overwriting the firmware-provided values with values of its own. There are
some switch features that require preliminary FLOGI's that are
switch-specific and done prior to the actual fabric FLOGI for traffic. The
fw will perform those FLOGIs and will revise the service parameters for the
features configured. As the driver later overwrites those values with its
own values, it misconfigures things like BBSCN use by doing so.
Correct by eliminating the driver-overwrite of firmware values. The driver
correctly re-reads the service parameters after each link up to obtain the
latest values from firmware.

[ Upstream commit e3ba04c9bad1d1c7f15df43da25e878045150777 ]
There are reports of multiple ports on the same system displaying different
hostnames in fabric FDMI displays.
Currently, the driver registers the hostname at initialization and obtains
the hostname via init_utsname()->nodename queried at the time the FC link
comes up. Unfortunately, if the machine hostname is updated after
initialization, such as via DHCP or admin command, the value registered
initially will be incorrect.
Fix by having the driver save the hostname that was registered with FDMI.
The driver then runs a heartbeat action that will check the hostname. If
the name changes, reregister the FMDI data.
The hostname is used in RSNN_NN, FDMI RPA and FDMI RHBA.

[ Upstream commit 93a4d6f40198dffcca35d9a928c409f9290f1fe0 ]
The recent affinitization didn't address cpu offlining/onlining. If an
interrupt vector is shared and the low order cpu owning the vector is
offlined, as interrupts are managed, the vector is taken offline. This
causes the other CPUs sharing the vector will hang as they can't get io
completions.
Correct by registering callbacks with the system for Offline/Online
events. When a cpu is taken offline, its eq, which is tied to an interrupt
vector is found. If the cpu is the "owner" of the vector and if the
eq/vector is shared by other CPUs, the eq is placed into a polled mode.
Additionally, code paths that perform io submission on the "sharing CPUs"
will check the eq state and poll for completion after submission of new io
to a wq that uses the eq.
Similarly, when a cpu comes back online and owns an offlined vector, the eq
is taken out of polled mode and rearmed to start driving interrupts for eq.

Add missing casts when converting from regions to sectors.
In case BITS_PER_LONG == 32, the lack of the appropriate casts can lead
to overflows and miscalculation of the device sector.
As a result, we could end up discarding and/or copying the wrong parts

[ Upstream commit 4b5142905d4ff58a4b93f7c8eaa7ba829c0a53c9 ]
There is a bug in the way dm-clone handles discards, which can lead to
discarding the wrong blocks or trying to discard blocks beyond the end
of the device.
This could lead to data corruption, if the destination device indeed
discards the underlying blocks, i.e., if the discard operation results
in the original contents of a block to be lost.
The root of the problem is the code that calculates the range of regions
covered by a discard request and decides which regions to discard.
Since dm-clone handles the device in units of regions, we don't discard
parts of a region, only whole regions.
The range is calculated as:
rs = dm_sector_div_up(bio->bi_iter.bi_sector, clone->region_size);
re = bio_end_sector(bio) >> clone->region_shift;
, where 'rs' is the first region to discard and (re - rs) is the number
of regions to discard.
The bug manifests when we try to discard part of a single region, i.e.,
when we try to discard a block with size < region_size, and the discard
request both starts at an offset with respect to the beginning of that
region and ends before the end of the region.
The root cause is the following comparison:
if (rs == re)
// skip discard and complete original bio immediately
, which doesn't take into account that 'rs' might be greater than 're'.
Thus, we then issue a discard request for the wrong blocks, instead of
skipping the discard all together.
Fix the check to also take into account the above case, so we don't end
up discarding the wrong blocks.
Also, add some range checks to dm_clone_set_region_hydrated() and
dm_clone_cond_set_range(), which update dm-clone's region bitmap.
Note that the aforementioned bug doesn't cause invalid memory accesses,
because dm_clone_is_range_hydrated() returns True for this case, so the
checks are just precautionary.

[ Upstream commit b8fdd090376a7a46d17db316638fe54b965c2fb0 ]
zmd->nr_rnd_zones was increased twice by mistake. The other place it
is increased in dmz_init_zone() is the only one needed:
1131 zmd->nr_useable_zones++;
1132 if (dmz_is_rnd(zone)) {
1133 zmd->nr_rnd_zones++;

commit cc41f11a21a51d6869d71e525a7264c748d7c0d7 upstream.
Generic protection fault type kernel panic is observed when user performs
soft (ordered) HBA unplug operation while IOs are running on drives
connected to HBA.
When user performs ordered HBA removal operation, the kernel calls PCI
device's .remove() call back function where driver is flushing out all the
outstanding SCSI IO commands with DID_NO_CONNECT host byte and also unmaps
sg buffers allocated for these IO commands.
However, in the ordered HBA removal case (unlike of real HBA hot removal),
HBA device is still alive and hence HBA hardware is performing the DMA
operations to those buffers on the system memory which are already unmapped
while flushing out the outstanding SCSI IO commands and this leads to
kernel panic.
Don't flush out the outstanding IOs from .remove() path in case of ordered
removal since HBA will be still alive in this case and it can complete the
outstanding IOs. Flush out the outstanding IOs only in case of 'physical
HBA hot unplug' where there won't be any communication with the HBA.
During shutdown also it is possible that HBA hardware can perform DMA
operations on those outstanding IO buffers which are completed with
DID_NO_CONNECT by the driver from .shutdown(). So same above fix is applied
in shutdown path as well.
It is safe to drop the outstanding commands when HBA is inaccessible such
as when permanent PCI failure happens, when HBA is in non-operational
state, or when someone does a real HBA hot unplug operation. Since driver
knows that HBA is inaccessible during these cases, it is safe to drop the
outstanding commands instead of waiting for SCSI error recovery to kick in
and clear these outstanding commands.

commit 3a169c0be75b59dd85d159493634870cdec6d3c4 upstream.
Commit 1d5c76e664333 ("xen-blkfront: switch kcalloc to kvcalloc for
large array allocation") didn't fix the issue it was meant to, as the
flags for allocating the memory are GFP_NOIO, which will lead the
memory allocation falling back to kmalloc().
So instead of GFP_NOIO use GFP_KERNEL and do all the memory allocation
in blkfront_setup_indirect() in a memalloc_noio_{save,restore} section.

commit 32830a0534700f86366f371b150b17f0f0d140d7 upstream.
The wait_event() function is used to detect command completion.
When send_guid_cmd() returns an error, smi_send() has not been
called to send data. Therefore, wait_event() should not be used

commit d0a72efac89d1c35ac55197895201b7b94c5e6ef upstream.
The cpufreq driver has a use-after-free that we can hit if:
a) There's an OCC message pending when the notifier is registered, and
b) The cpufreq driver fails to register with the core.
When a) occurs the notifier schedules a workqueue item to handle the
message. The backing work_struct is located on chips[].throttle and
when b) happens we clean up by freeing the array. Once we get to
the (now free) queued item and the kernel crashes.

commit ebc68cedec4aead47d8d11623d013cca9bf8e825 upstream.
The Acer Aspire 5738z has a button to disable (and re-enable) the
touchpad next to the touchpad.
When this button is pressed a LED underneath indicates that the touchpad
is disabled (and an event is send to userspace and GNOME shows its
touchpad enabled / disable OSD thingie).
So far so good, but after re-enabling the touchpad it no longer works.
The laptop does not have an external ps2 port, so mux mode is not needed
and disabling mux mode fixes the touchpad no longer working after toggling
it off and back on again, so lets add this laptop model to the nomux list.

commit 819732be9fea728623e1ed84eba28def7384ad1f upstream.
v2.6.27 commit cc8c282963bd ("[SCSI] zfcp: Automatically attach remote
ports") introduced zfcp automatic port scan.
Before that, the user had to use the sysfs attribute "port_add" of an FCP
device (adapter) to add and open remote (target) ports, even for the remote
peer port in point-to-point topology. That code path did a proper port open
recovery trigger taking the erp_lock.
Since above commit, a new helper function zfcp_erp_open_ptp_port()
performed an UNlocked port open recovery trigger. This can race with other
parallel recovery triggers. In zfcp_erp_action_enqueue() this could corrupt
e.g. adapter->erp_total_count or adapter->erp_ready_head.
As already found for fabric topology in v4.17 commit fa89adba1941 ("scsi:
zfcp: fix infinite iteration on ERP ready list"), there was an endless loop
during tracing of rport (un)block. A subsequent v4.18 commit 9e156c54ace3
("scsi: zfcp: assert that the ERP lock is held when tracing a recovery
trigger") introduced a lockdep assertion for that case.
As a side effect, that lockdep assertion now uncovered the unlocked code
path for PtP. It is from within an adapter ERP action:
zfcp_erp_strategy[1479] intentionally DROPs erp lock around
zfcp_erp_strategy_do_action()
zfcp_erp_strategy_do_action[1441] NO erp lock
zfcp_erp_adapter_strategy[876] NO erp lock

zfcp_erp_adapter_strat_fsf_xconf[772] erp lock only around

zfcp_dbf_rec_trig[288] _checks_ to be called with erp lock:

It causes the following lockdep warning:

commit 8962c6d2c2b8ca51b0f188109015b15fc5f4da44 upstream.
Remove the auth tag size from cryptlen before mapping the destination
in out-of-place AEAD decryption thus resolving a crash with
extended testmgr tests.

commit 504e84abec7a635b861afd8d7f92ecd13eaa2b09 upstream.
Make sure to only add the size of the auth tag to the source mapping
for encryption if it is an in-place operation. Failing to do this
previously caused us to try and map auth size len bytes from a NULL
mapping and crashing if both the cryptlen and assoclen are zero.

commit ce0fc6db38decf0d2919bfe783de6d6b76e421a9 upstream.
Deal gracefully with a NULL or empty scatterlist which can happen
if both cryptlen and assoclen are zero and we're doing in-place
AEAD encryption.
This fixes a crash when this causes us to try and map a NULL page,
at least with some platforms / DMA mapping configs.

commit 3f142b6a7b573bde6cff926f246da05652c61eb4 upstream.
Since in the software implementation of XTS-AES there is
no notion of sector every input length is processed the same way.
CAAM implementation has the notion of sector which causes different
results between the software implementation and the one in CAAM
for input lengths bigger than 512 bytes.
Increase sector size to maximum value on 16 bits.

commit 3a5a9e1ef37b030b836d92df8264f840988f4a38 upstream.
HW generates a Data Size error for chacha20 requests that are not
a multiple of 64B, since algorithm state (AS) does not have
the FINAL bit set.
Since updating req->iv (for chaining) is not required,
modify skcipher descriptors to set the FINAL bit for chacha20.
[Note that for skcipher decryption we know that ctx1_iv_off is 0,
which allows for an optimization by not checking algorithm type,
since append_dec_op1() sets FINAL bit for all algorithms except AES.]
Also drop the descriptor operations that save the IV.
However, in order to keep code logic simple, things like
S/G tables generation etc. are not touched.

commit 81d5553d1288c2ec0390f02f84d71ca0f0f9f137 upstream.
dm_clone_nr_of_hydrated_regions() returns the number of regions that
have been hydrated so far. In order to do so it employs bitmap_weight().
Until now, the return type of dm_clone_nr_of_hydrated_regions() was
unsigned long.
Because bitmap_weight() returns an int, in case BITS_PER_LONG == 64 and
the return value of bitmap_weight() is 2^31 (the maximum allowed number
of regions for a device), the result is sign extended from 32 bits to 64
bits and an incorrect value is displayed, in the status output of
dm-clone, as the number of hydrated regions.
Fix this by having dm_clone_nr_of_hydrated_regions() return an unsigned
int.

commit cd481c12269b4d276f1a52eda0ebd419079bfe3a upstream.
Add overflow check for clone->nr_regions variable, which holds the
number of regions of the target.
The overflow can occur with sufficiently large devices, if BITS_PER_LONG
== 32. E.g., if the region size is 8 sectors (4K), the overflow would
occur for device sizes > 34359738360 sectors (~16TB).
This could result in multiple device sectors wrongly mapping to the same
region number, due to the truncation from 64 bits to 32 bits, which
would lead to data corruption.

allocated for each dm-verity-fec device. But it is not freed when
dm-table for the verity target is removed. Hence free the output

Undefined rproc_ops .kick method in remoteproc driver will result in
"Unable to handle kernel NULL pointer dereference" in rproc_virtio_notify,
after firmware loading if:
1) .kick method wasn't defined in driver
2) resource_table exists in firmware and has "Virtio device entry" defined
Let's refuse to register an rproc-induced virtio device if no kick method was
defined for rproc.

commit d96f2571dc84d128cacf1944f4ecc87834c779a6 upstream.
On secure devices after a wdog/fatal interrupt, the mba region has to be
refreshed in order to prevent the following errors during mba load.

commit 900fc60df22748dbc28e4970838e8f7b8f1013ce upstream.
Trying to reclaim mpss memory while the mba is not running causes the
system to crash on devices with security fuses blown, so leave it
assigned to the remote on shutdown and recover it on a subsequent boot.

commit b645ad39d56846618704e463b24bb994c9585c7f upstream.
Currently when marking a block, we use spinand_erase_op() to erase
the block before writing the marker to the OOB area. Doing so without
waiting for the operation to finish can lead to the marking failing
silently and no bad block marker being written to the flash.
In fact we don't need to do an erase at all before writing the BBM.
The ECC is disabled for raw accesses to the OOB data and we don't
need to work around any issues with chips reporting ECC errors as it
is known to be the case for raw NAND.
