MWAIT is advertised in host is not overcommitted scenario, however, PV
TLB/sched yield should be enabled in host overcommitted scenario. Let's
add the MWAIT checking when enabling PV TLB/sched yield.

KVM/arm64 fixes for 5.17, take #4
- Correctly synchronise PMR and co on PSCI CPU_SUSPEND
- Skip tests that depend on GICv3 when the HW isn't available
|
|
The arch_timer and vgic_irq kselftests assume that they can create a
vgic-v3, using the library function vgic_v3_setup() which aborts with a
test failure if it is not possible to do so. Since vgic-v3 can only be
instantiated on systems where the host has GICv3 this leads to false
positives on older systems where that is not the case.
Fix this by changing vgic_v3_setup() to return an error if the vgic can't
be instantiated and have the callers skip if this happens. We could also
exit flagging a skip in vgic_v3_setup() but this would prevent future test
cases conditionally deciding which GIC to use or generally doing more
complex output.

====================
ibmvnic: Fix a race in ibmvnic_probe()
If we get a transport (reset) event right after a successful CRQ_INIT
during ibmvnic_probe() but before we set the adapter state to VNIC_PROBED,
we will throw away the reset assuming that the adapter is still in the
probing state. But since the adapter has completed the CRQ_INIT any
subsequent CRQs the we send will be ignored by the vnicserver until
we release/init the CRQ again. This can leave the adapter unconfigured.
While here fix a couple of other bugs that were observed (Patches 1,2,4).

We currently don't allow queuing resets when adapter is in VNIC_PROBING
state - instead we throw away the reset and return EBUSY. The reasoning
is probably that during ibmvnic_probe() the ibmvnic_adapter itself is
being initialized so performing a reset during this time can lead us to
accessing fields in the ibmvnic_adapter that are not fully initialized.
A review of the code shows that all the adapter state neede to process a
reset is initialized before registering the CRQ so that should no longer
be a concern.
Further the expectation is that if we do get a reset (transport event)
during probe, the do..while() loop in ibmvnic_probe() will handle this
by reinitializing the CRQ.
While that is true to some extent, it is possible that the reset might
occur _after_ the CRQ is registered and CRQ_INIT message was exchanged
but _before_ the adapter state is set to VNIC_PROBED. As mentioned above,
such a reset will be thrown away. While the client assumes that the
adapter is functional, the vnic server will wait for the client to reinit
the adapter. This disconnect between the two leaves the adapter down
needing manual intervention.
Because ibmvnic_probe() has other work to do after initializing the CRQ
(such as registering the netdev at a minimum) and because the reset event
can occur at any instant after the CRQ is initialized, there will always
be a window between initializing the CRQ and considering the adapter
ready for resets (ie state == PROBED).
So rather than discarding resets during this window, allow queueing them
- but only process them after the adapter is fully initialized.
To do this, introduce a new completion state ->probe_done and have the
reset worker thread wait on this before processing resets.
This change brings up two new situations in or just after ibmvnic_probe().
First after one or more resets were queued, we encounter an error and
decide to retry the initialization. At that point the queued resets are
no longer relevant since we could be talking to a new vnic server. So we
must purge/flush the queued resets before restarting the initialization.
As a side note, since we are still in the probing stage and we have not
registered the netdev, it will not be CHANGE_PARAM reset.
Second this change opens up a potential race between the worker thread
in __ibmvnic_reset(), the tasklet and the ibmvnic_open() due to the
following sequence of events:
1. Register CRQ
2. Get transport event before CRQ_INIT completes.
3. Tasklet schedules reset:
a) add rwi to list
b) schedule_work() to start worker thread which runs
and waits for ->probe_done.
4. ibmvnic_probe() decides to retry, purges rwi_list
5. Re-register crq and this time rest of probe succeeds - register
netdev and complete(->probe_done).
6. Worker thread resumes in __ibmvnic_reset() from 3b.
7. Worker thread sets ->resetting bit
8. ibmvnic_open() comes in, notices ->resetting bit, sets state
to IBMVNIC_OPEN and returns early expecting worker thread to
finish the open.
9. Worker thread finds rwi_list empty and returns without
opening the interface.
If this happens, the ->ndo_open() call is effectively lost and the
interface remains down. To address this, ensure that ->rwi_list is
not empty before setting the ->resetting bit. See also comments in
__ibmvnic_reset().

Clear ->failover_pending flag that may have been set in the previous
pass of registering CRQ. If we don't clear, a subsequent ibmvnic_open()
call would be misled into thinking a failover is pending and assuming
that the reset worker thread would open the adapter. If this pass of
registering the CRQ succeeds (i.e there is no transport event), there
wouldn't be a reset worker thread.
This would leave the adapter unconfigured and require manual intervention
to bring it up during boot.

We currently initialize the ->init_done completion/return code fields
before issuing a CRQ_INIT command. But if we get a transport event soon
after registering the CRQ the taskslet may already have recorded the
completion and error code. If we initialize here, we might overwrite/
lose that and end up issuing the CRQ_INIT only to timeout later.
If that timeout happens during probe, we will leave the adapter in the
DOWN state rather than retrying to register/init the CRQ.
Initialize the completion before registering the CRQ so we don't lose
the notification.

If I'm not mistaken (and I don't think I am), the way in which the
dcbnl_ops work is that drivers call dcb_ieee_setapp() and this populates
the application table with dynamically allocated struct dcb_app_type
entries that are kept in the module-global dcb_app_list.
However, nobody keeps exact track of these entries, and although
dcb_ieee_delapp() is supposed to remove them, nobody does so when the
interface goes away (example: driver unbinds from device). So the
dcb_app_list will contain lingering entries with an ifindex that no
longer matches any device in dcb_app_lookup().
Reclaim the lost memory by listening for the NETDEV_UNREGISTER event and
flushing the app table entries of interfaces that are now gone.
In fact something like this used to be done as part of the initial
commit (blamed below), but it was done in dcbnl_exit() -> dcb_flushapp(),
essentially at module_exit time. That became dead code after commit
7a6b6f515f77 ("DCB: fix kconfig option") which essentially merged
"tristate config DCB" and "bool config DCBNL" into a single "bool config
DCB", so net/dcb/dcbnl.c could not be built as a module anymore.
Commit 36b9ad8084bd ("net/dcb: make dcbnl.c explicitly non-modular")
recognized this and deleted dcbnl_exit() and dcb_flushapp() altogether,
leaving us with the version we have today.
Since flushing application table entries can and should be done as soon
as the netdevice disappears, fundamentally the commit that is to blame
is the one that introduced the design of this API.

There's a potential leak issue under following execution sequence :
smc_release smc_connect_work
if (sk->sk_state == SMC_INIT)
send_clc_confirim
tcp_abort();
...
sk.sk_state = SMC_ACTIVE
smc_close_active
switch(sk->sk_state) {
...
case SMC_ACTIVE:
smc_close_final()
// then wait peer closed
Unfortunately, tcp_abort() may discard CLC CONFIRM messages that are
still in the tcp send buffer, in which case our connection token cannot
be delivered to the server side, which means that we cannot get a
passive close message at all. Therefore, it is impossible for the to be
disconnected at all.
This patch tries a very simple way to avoid this issue, once the state
has changed to SMC_ACTIVE after tcp_abort(), we can actively abort the
smc connection, considering that the state is SMC_INIT before
tcp_abort(), abandoning the complete disconnection process should not
cause too much problem.
In fact, this problem may exist as long as the CLC CONFIRM message is
not received by the server. Whether a timer should be added after
smc_close_final() needs to be discussed in the future. But even so, this
patch provides a faster release for connection in above case, it should
also be valuable.

In this driver's ->ndo_open() callback, it enables DMA interrupts,
starts the DMA channels, then requests interrupts with request_irq(),
and then finally enables napi.
If RX DMA interrupts are received before napi is enabled, no processing
is done because napi_schedule_prep() will return false. If the network
has a lot of broadcast/multicast traffic, then the RX ring could fill up
completely before napi is enabled. When this happens, no further RX
interrupts will be delivered, and the driver will fail to receive any
packets.
Fix this by only enabling DMA interrupts after all other initialization
is complete.

xennet_destroy_queues() relies on info->netdev->real_num_tx_queues to
delete queues. Since d7dac083414eb5bb99a6d2ed53dc2c1b405224e5
("net-sysfs: update the queue counts in the unregistration path"),
unregister_netdev() indirectly sets real_num_tx_queues to 0. Those two
facts together means, that xennet_destroy_queues() called from
xennet_remove() cannot do its job, because it's called after
unregister_netdev(). This results in kfree-ing queues that are still
linked in napi, which ultimately crashes:

Revert back to refreshing vmcs.HOST_CR3 immediately prior to VM-Enter.
The PCID (ASID) part of CR3 can be bumped without KVM being scheduled
out, as the kernel will switch CR3 during __text_poke(), e.g. in response
to a static key toggling. If switch_mm_irqs_off() chooses a new ASID for
the mm associate with KVM, KVM will do VM-Enter => VM-Exit with a stale
vmcs.HOST_CR3.
Add a comment to explain why KVM must wait until VM-Enter is imminent to
refresh vmcs.HOST_CR3.
The following splat was captured by stashing vmcs.HOST_CR3 in kvm_vcpu
and adding a WARN in load_new_mm_cr3() to fire if a new ASID is being
loaded for the KVM-associated mm while KVM has a "running" vCPU:

The driver uses an atomic_t variable: gs_usb:active_channels to keep
track of the number of opened channels in order to only allocate
memory for the URBs when this count changes from zero to one.
However, the driver does not decrement the counter when an error
occurs in gs_can_open(). This issue is fixed by changing the type from
atomic_t to u8 and by simplifying the logic accordingly.
It is safe to use an u8 here because the network stack big kernel lock
(a.k.a. rtnl_mutex) is being hold. For details, please refer to [1].

The driver uses an atomic_t variable: struct
es58x_device::opened_channel_cnt to keep track of the number of opened
channels in order to only allocate memory for the URBs when this count
changes from zero to one.
While the intent was to prevent race conditions, the choice of an
atomic_t turns out to be a bad idea for several reasons:
- implementation is incorrect and fails to decrement
opened_channel_cnt when the URB allocation fails as reported in
[1].
- even if opened_channel_cnt were to be correctly decremented,
atomic_t is insufficient to cover edge cases: there can be a race
condition in which 1/ a first process fails to allocate URBs
memory 2/ a second process enters es58x_open() before the first
process does its cleanup and decrements opened_channed_cnt. In
which case, the second process would successfully return despite
the URBs memory not being allocated.
- actually, any kind of locking mechanism was useless here because
it is redundant with the network stack big kernel lock
(a.k.a. rtnl_lock) which is being hold by all the callers of
net_device_ops:ndo_open() and net_device_ops:ndo_close(). c.f. the
ASSERST_RTNL() calls in __dev_open() [2] and __dev_close_many()
[3].
The atmomic_t is thus replaced by a simple u8 type and the logic to
increment and decrement es58x_device:opened_channel_cnt is simplified
accordingly fixing the bug reported in [1]. We do not check again for
ASSERST_RTNL() as this is already done by the callers.

The MPTCP SIOCOUTQ implementation is not very accurate in
case of fallback: it only measures the data in the MPTCP-level
write queue, but it does not take in account the subflow
write queue utilization. In case of fallback the first can be
empty, while the latter is not.
The above produces sporadic self-tests issues and can foul
legit user-space application.
Fix the issue additionally querying the subflow in case of fallback.

GDSCs have multiple transition delays which are used for the GDSC FSM
states. Older targets/designs required these values to be updated from
gdsc code to certain default values for the FSM state to work as
expected. But on the newer targets/designs the values updated from the

On SC7180 we observe black screens because the gdsc is being

Pull pci fixes from Bjorn Helgaas:
- Fix a merge error that broke PCI device enumeration on mvebu
platforms, including Turris Omnia (Armada 385) (Pali Rohár)
- Avoid using ATS on all AMD Navi10 and Navi14 GPUs because some
VBIOSes don't account for "harvested" (disabled) parts of the chip
when initializing caches (Alex Deucher)
