SW Steering uses RC QP for writing STEs to ICM. This writingis done in LB
(loopback), and FL (force-loopback) QP is preferred for performance. FL is
available when RoCE is enabled or disabled based on RoCE caps.
This patch adds reading of FL capability from HCA caps in addition to the
existing reading from RoCE caps, thus fixing the case where we didn't
have loopback enabled when RoCE was disabled.

When calculating crc for hash index we use the function crc32 that
calculates for little-endian (LE) arch.
Then we convert it to network endianness using htonl(), but it's wrong
to do the conversion in BE archs since the crc32 value is already LE.
The solution is to switch the bytes from the crc result for all types
of arc.

In case user switch a device from switchdev mode to legacy mode, mlx5
first unpair the E-switch and afterwards unload the uplink vport.
From the other hand, in case user remove or reload a device, mlx5
first unload the uplink vport and afterwards unpair the E-switch.
The latter is causing a bug[1], hence, handle pairing of E-switch as
part of uplink un/load APIs.
[1]
In case VF_LAG is used, every tc fdb flow is duplicated to the peer
esw. However, the original esw keeps a pointer to this duplicated
flow, not the peer esw.
e.g.: if user create tc fdb flow over esw0, the flow is duplicated
over esw1, in FW/HW, but in SW, esw0 keeps a pointer to the duplicated
flow.
During module unload while a peer tc fdb flow is still offloaded, in
case the first device to be removed is the peer device (esw1 in the
example above), the peer net-dev is destroyed, and so the mlx5e_priv
is memset to 0.
Afterwards, the peer device is trying to unpair himself from the
original device (esw0 in the example above). Unpair API invoke the
original device to clear peer flow from its eswitch (esw0), but the
peer flow, which is stored over the original eswitch (esw0), is
trying to use the peer mlx5e_priv, which is memset to 0 and result in
bellow kernel-oops.

DEVX can issue a general command, which is not used by mlx5 driver.
In case such command is failed, mlx5 is trying to collect the failure
data, However, mlx5 doesn't create a storage for this command, since
mlx5 doesn't use it. This lead to array-index-out-of-bounds error.

When target mode is enabled, the pci_irq_get_affinity() function may return
a NULL value in qla_mapq_init_qp_cpu_map() due to the qla24xx_enable_msix()
code that handles IRQ settings for target mode. This leads to a crash due
to a NULL pointer dereference.
This patch fixes the issue by adding a check for the NULL value returned by
pci_irq_get_affinity() and introducing a 'cpu_mapped' boolean flag to the
qla_qpair structure, ensuring that the qpair's CPU affinity is updated when
it has not been mapped to a CPU.

The tpg->np_login_sem is a semaphore that is used to serialize the login
process when multiple login threads run concurrently against the same
target portal group.
The iscsi_target_locate_portal() function finds the tpg, calls
iscsit_access_np() against the np_login_sem semaphore and saves the tpg
pointer in conn->tpg;
If iscsi_target_locate_portal() fails, the caller will check for the
conn->tpg pointer and, if it's not NULL, then it will assume that
iscsi_target_locate_portal() called iscsit_access_np() on the semaphore.
Make sure that conn->tpg gets initialized only if iscsit_access_np() was
successful, otherwise iscsit_deaccess_np() may end up being called against
a semaphore we never took, allowing more than one thread to access the same
tpg.

If the initiator suddenly stops sending data during a login while keeping
the TCP connection open, the login_work won't be scheduled and will never
release the login semaphore; concurrent login operations will therefore get
stuck and fail.
The bug is due to the inability of the login timeout code to properly
handle this particular case.
Fix the problem by replacing the old per-NP login timer with a new
per-connection timer.
The timer is started when an initiator connects to the target; if it
expires, it sends a SIGINT signal to the thread pointed at by the
conn->login_kworker pointer.
conn->login_kworker is set by calling the iscsit_set_login_timer_kworker()
helper, initially it will point to the np thread; When the login
operation's control is in the process of being passed from the NP-thread to
login_work, the conn->login_worker pointer is set to NULL. Finally,
login_kworker will be changed to point to the worker thread executing the
login_work job.
If conn->login_kworker is NULL when the timer expires, it means that the
login operation hasn't been completed yet but login_work isn't running, in
this case the timer will mark the login process as failed and will schedule
login_work so the latter will be forced to free the resources it holds.

The LRU and LRU_PERCPU maps allocate a new element on update before locking the
target hash table bucket. Right after that the maps try to lock the bucket.
If this fails, then maps return -EBUSY to the caller without releasing the
allocated element. This makes the element untracked: it doesn't belong to
either of free lists, and it doesn't belong to the hash table, so can't be
re-used; this eventually leads to the permanent -ENOMEM on LRU map updates,
which is unexpected. Fix this by returning the element to the local free list
if bucket locking fails.

When running on an AMD vIOMMU, we observed multiple invalidations (of
decreasing power of 2 aligned sizes) when unmapping a single page.
Domain flush takes gather bounds (end-start) as size param. However,
gather->end is defined as the last inclusive address (start + size - 1).
This leads to an off by 1 error.
With this patch, verified that 1 invalidation occurs when unmapping a
single page.

This ended up providing an empty UNMANAGED domain when the core code asked

GALog exists to propagate interrupts into all vCPUs in the system when
interrupts are marked as non running (e.g. when vCPUs aren't running). A
GALog overflow happens when there's in no space in the log to record the
GATag of the interrupt. So when the GALOverflow condition happens, the
GALog queue is processed and the GALog is restarted, as the IOMMU
manual indicates in section "2.7.4 Guest Virtual APIC Log Restart
Procedure":
| * Wait until MMIO Offset 2020h[GALogRun]=0b so that all request
| entries are completed as circumstances allow. GALogRun must be 0b to
| modify the guest virtual APIC log registers safely.
| * Write MMIO Offset 0018h[GALogEn]=0b.
| * As necessary, change the following values (e.g., to relocate or
| resize the guest virtual APIC event log):
| - the Guest Virtual APIC Log Base Address Register
| [MMIO Offset 00E0h],
| - the Guest Virtual APIC Log Head Pointer Register
| [MMIO Offset 2040h][GALogHead], and
| - the Guest Virtual APIC Log Tail Pointer Register
| [MMIO Offset 2048h][GALogTail].
| * Write MMIO Offset 2020h[GALOverflow] = 1b to clear the bit (W1C).
| * Write MMIO Offset 0018h[GALogEn] = 1b, and either set
| MMIO Offset 0018h[GAIntEn] to enable the GA log interrupt or clear
| the bit to disable it.
Failing to handle the GALog overflow means that none of the VFs (in any
guest) will work with IOMMU AVIC forcing the user to power cycle the
host. When handling the event it resumes the GALog without resizing
much like how it is done in the event handler overflow. The
[MMIO Offset 2020h][GALOverflow] bit might be set in status register
without the [MMIO Offset 2020h][GAInt] bit, so when deciding to poll
for GA events (to clear space in the galog), also check the overflow
bit.

On KVM GSI routing table updates, specially those where they have vIOMMUs
with interrupt remapping enabled (to boot >255vcpus setups without relying
on KVM_FEATURE_MSI_EXT_DEST_ID), a VMM may update the backing VF MSIs
with a new VCPU affinity.
On AMD with AVIC enabled, the new vcpu affinity info is updated via:
avic_pi_update_irte()
irq_set_vcpu_affinity()
amd_ir_set_vcpu_affinity()
amd_iommu_{de}activate_guest_mode()
Where the IRTE[GATag] is updated with the new vcpu affinity. The GATag
contains VM ID and VCPU ID, and is used by IOMMU hardware to signal KVM
(via GALog) when interrupt cannot be delivered due to vCPU is in
blocking state.
The issue is that amd_iommu_activate_guest_mode() will essentially
only change IRTE fields on transitions from non-guest-mode to guest-mode
and otherwise returns *with no changes to IRTE* on already configured
guest-mode interrupts. To the guest this means that the VF interrupts
remain affined to the first vCPU they were first configured, and guest
will be unable to issue VF interrupts and receive messages like this
from spurious interrupts (e.g. from waking the wrong vCPU in GALog):
[ 167.759472] __common_interrupt: 3.34 No irq handler for vector
[ 230.680927] mlx5_core 0000:00:02.0: mlx5_cmd_eq_recover:247:(pid

recovered after timeout
[ 230.683266] __common_interrupt: 3.34 No irq handler for vector
Given the fact that amd_ir_set_vcpu_affinity() uses
amd_iommu_activate_guest_mode() underneath it essentially means that VCPU
affinity changes of IRTEs are nops. Fix it by dropping the check for
guest-mode at amd_iommu_activate_guest_mode(). Same thing is applicable to
amd_iommu_deactivate_guest_mode() although, even if the IRTE doesn't change
underlying DestID on the host, the VFIO IRQ handler will still be able to
poke at the right guest-vCPU.

drivers/iommu/rockchip-iommu.c:1306 rk_iommu_probe() warn: missing unwind goto?
The rk_iommu_probe function, after obtaining the irq value through
platform_get_irq, directly returns an error if the returned value
is negative, without releasing any resources.
Fix this by adding a new error handling label "err_pm_disable" and
use a goto statement to redirect to the error handling process. In
order to preserve the original semantics, set err to the value of irq.

For a bigjoiner configuration display->crtc_disable() will be called
first for the slave CRTCs and then for the master CRTC. However slave
CRTCs will be actually disabled only after the master CRTC is disabled
(from the encoder disable hooks called with the master CRTC state).
Hence the slave PIPEDMCs can be disabled only after the master CRTC is
disabled, make this so.
intel_encoders_post_pll_disable() must be called only for the master
CRTC, as for the other two encoder disable hooks. While at it fix this
up as well. This didn't cause a problem, since
intel_encoders_post_pll_disable() will call the corresponding hook only
for an encoder/connector connected to the given CRTC, however slave
CRTCs will have no associated encoder/connector.

syzbot is reporting a lockdep warning in fill_pool() because the allocation
from debugobjects is using GFP_ATOMIC, which is (__GFP_HIGH | __GFP_KSWAPD_RECLAIM)
and therefore tries to wake up kswapd, which acquires kswapd_wait::lock.
Since fill_pool() might be called with arbitrary locks held, fill_pool()
should not assume that acquiring kswapd_wait::lock is safe.
Use __GFP_HIGH instead and remove __GFP_NORETRY as it is pointless for
!__GFP_DIRECT_RECLAIM allocation.

It's reported that the recording started right after the driver probe
doesn't work properly, and it turned out that this is related with the
codec auto-suspend. Namely, after the probe phase, the usage count
goes zero, and the auto-suspend is programmed, but the codec is kept
still active until the auto-suspend expiration. When an application
(e.g. alsactl) updates the mixer values at this moment, the values are
cached but not actually written. Then, starting arecord thereafter
also results in the silence because of the missing unmute.
The root cause is the handling of "lazy update" mode; when a mixer
value is updated *after* the suspend, it should update only the cache
and exits. At the resume, the cached value is written to the device,
in turn. The problem is that the current code misinterprets the state
of auto-suspend as if it were already suspended.
Although we can add the check of the actual device state after
pm_runtime_get_if_in_use() for catching the missing state, this won't
suffice; the second call of regmap_update_bits_check() will skip
writing the register because the cache has been already updated by the
first call. So we'd need fixes in two different places.
OTOH, a simpler fix is to replace pm_runtime_get_if_in_use() with
pm_runtime_get_if_active() (with ign_usage_count=true). This change
implies that the driver takes the pm refcount if the device is still
in ACTIVE state and continues the processing. A small caveat is that
this will leave the auto-suspend timer. But, since the timer callback
itself checks the device state and aborts gracefully when it's active,
this won't be any substantial problem.
Long story short: we address the missing register-write problem just
by replacing the pm_runtime_*() call in snd_hda_keep_power_up().

On 68030/020, an instruction such as, moveml %a2-%a3/%a5,%sp@- may cause
a stack page fault during instruction execution (i.e. not at an
instruction boundary) and produce a format 0xB exception frame.
In this situation, the value of USP will be unreliable. If a signal is
to be delivered following the exception, this USP value is used to
calculate the location for a signal frame. This can result in a
corrupted user stack.
The corruption was detected in dash (actually in glibc) where it showed
up as an intermittent "stack smashing detected" message and crash
following signal delivery for SIGCHLD.
It was hard to reproduce that failure because delivery of the signal
raced with the page fault and because the kernel places an unpredictable
gap of up to 7 bytes between the USP and the signal frame.
A format 0xB exception frame can be produced by a bus error or an
address error. The 68030 Users Manual says that address errors occur
immediately upon detection during instruction prefetch. The instruction
pipeline allows prefetch to overlap with other instructions, which means
an address error can arise during the execution of a different
instruction. So it seems likely that this patch may help in the address
error case also.

In mutex_init() lockdep identifies a lock by defining a special static
key for each lock class. However if we wrap the macro in a function,
like in drmm_mutex_init(), we end up generating:
int drmm_mutex_init(struct drm_device *dev, struct mutex *lock)
{
static struct lock_class_key __key;
__mutex_init((lock), "lock", &__key);
....
}
The static __key here is what lockdep uses to identify the lock class,
however since this is just a normal function the key here will be
created once, where all callers then use the same key. In effect the
mutex->depmap.key will be the same pointer for different
drmm_mutex_init() callers. This then results in impossible lockdep
splats since lockdep thinks completely unrelated locks are the same lock
class.
To fix this turn drmm_mutex_init() into a macro such that it generates a
different "static struct lock_class_key __key" for each invocation,
which looks to be inline with what mutex_init() wants.
v2:
- Revamp the commit message with clearer explanation of the issue.
- Rather export __drmm_mutex_release() than static inline.

When doing plpmtu probe, the probe size is growing every time when it
receives the ACK during the Search state until the probe fails. When
the failure occurs, pl.probe_high is set and it goes to the Complete
state.
However, if the link pmtu is huge, like 65535 in loopback_dev, the probe
eventually keeps using SCTP_MAX_PLPMTU as the probe size and never fails.
Because of that, pl.probe_high can not be set, and the plpmtu probe can
never go to the Complete state.
Fix it by setting pl.probe_high to SCTP_MAX_PLPMTU when the probe size
grows to SCTP_MAX_PLPMTU in sctp_transport_pl_recv(). Also, not allow
the probe size greater than SCTP_MAX_PLPMTU in the Complete state.
