The merge of the CONFIG_PREEMPT_RT stub renamed CONFIG_PREEMPT to
CONFIG_PREEMPT_LL which causes all defconfigs which have CONFIG_PREEMPT=y
set to fall back to CONFIG_PREEMPT_NONE because CONFIG_PREEMPT depends on
the preemption mode choice wich defaults to NONE. This also affects
oldconfig builds.
So rather than changing 114 defconfig files and being an annoyance to
users, revert the rename and select a new config symbol PREEMPTION. That
keeps everything working smoothly and the revelant ifdef's are going to be
fixed up step by step.

Commit dd5142ca5d24 ("iommu/vt-d: Add debugfs support to show scalable mode
DMAR table internals") prints content of pasid table entries from LSB to
MSB where as other entries are printed MSB to LSB. So, to maintain
uniformity among all entries and to not confuse the user, print MSB first.

Following specification review a few things were changed in v8 of the
virtio-iommu series [1], but have been omitted when merging the base
driver. Add them now:
* Remove the EXEC flag.
* Add feature bit for the MMIO flag.
* Change domain_bits to domain_range.
* Add NOMEM status flag.

Since the cached32_node is allowed to be advanced above dma_32bit_pfn
(to provide a shortcut into the limited range), we need to be careful to
remove the to be freed node if it is the cached32_node.

There is a couple of places where on domain_init() failure domain_exit()
is called. While currently domain_init() can fail only if
alloc_pgtable_page() has failed.
Make domain_exit() check if domain->pgd present, before calling
domain_unmap(), as it theoretically should crash on clearing pte entries
in dma_pte_clear_level().

Intel VT-d driver was reworked to use common deferred flushing
implementation. Previously there was one global per-cpu flush queue,
afterwards - one per domain.
Before deferring a flush, the queue should be allocated and initialized.
Currently only domains with IOMMU_DOMAIN_DMA type initialize their flush
queue. It's probably worth to init it for static or unmanaged domains
too, but it may be arguable - I'm leaving it to iommu folks.
Prevent queuing an iova flush if the domain doesn't have a queue.
The defensive check seems to be worth to keep even if queue would be
initialized for all kinds of domains. And is easy backportable.
On 4.19.43 stable kernel it has a user-visible effect: previously for
devices in si domain there were crashes, on sata devices:

Comparing the arm-arm's pseudocode for AArch64.PCAlignmentFault() with
AArch64.SPAlignmentFault() shows that SP faults don't copy the faulty-SP
to FAR_EL1, but this is where we read from, and the address we provide
to user-space with the BUS_ADRALN signal.
For user-space this value will be UNKNOWN due to the previous ERET to
user-space. If the last value is preserved, on systems with KASLR or KPTI
this will be the user-space link-register left in FAR_EL1 by tramp_exit().
Fix this to retrieve the original sp_el0 value, and pass this to
do_sp_pc_fault().
SP alignment faults from EL1 will cause us to take the fault again when
trying to store the pt_regs. This eventually takes us to the overflow
stack. Remove the ESR_ELx_EC_SP_ALIGN check as we will never make it
this far.

A #GP is reported in the guest when requesting balloon inflation via
virtio-balloon. The reason is that the virtio-balloon driver has
removed the page from its internal page list (via balloon_page_pop),
but balloon_page_enqueue_one also calls "list_del" to do the removal.
This is necessary when it's used from balloon_page_enqueue_list, but
not from balloon_page_enqueue.
Move list_del to balloon_page_enqueue, and update comments accordingly.

As we have abandoned the home-made lazy domain allocation
and delegated the DMA domain life cycle up to the default
domain mechanism defined in the generic iommu layer, we
needn't consider pci alias anymore when mapping/unmapping

pointer dereference during pci device hot-plug test.

On a CPU that doesn't support SSBS, PSTATE[12] is RES0. In a system
where only some of the CPUs implement SSBS, we end-up losing track of

Jakub Kicinski says:
====================
John says:
Resolve a series of splats discovered by syzbot and an unhash
TLS issue noted by Eric Dumazet.
The main issues revolved around interaction between TLS and
sockmap tear down. TLS and sockmap could both reset sk->prot
ops creating a condition where a close or unhash op could be
called forever. A rare race condition resulting from a missing
rcu sync operation was causing a use after free. Then on the
TLS side dropping the sock lock and re-acquiring it during the
close op could hang. Finally, sockmap must be deployed before
tls for current stack assumptions to be met. This is enforced
now. A feature series can enable it.
To fix this first refactor TLS code so the lock is held for the
entire teardown operation. Then add an unhash callback to ensure
TLS can not transition from ESTABLISHED to LISTEN state. This
transition is a similar bug to the one found and fixed previously
in sockmap. Then apply three fixes to sockmap to fix up races
on tear down around map free and close. Finally, if sockmap
is destroyed before TLS we add a new ULP op update to inform
the TLS stack it should not call sockmap ops. This last one
appears to be the most commonly found issue from syzbot.
v4:
- fix some use after frees;
- disable disconnect work for offload (ctx lifetime is much
more complex);
- remove some of the dead code which made it hard to understand
(for me) that things work correctly (e.g. the checks TLS is
the top ULP);
- add selftets.

When a map free is called and in parallel a socket is closed we
have two paths that can potentially reset the socket prot ops, the
bpf close() path and the map free path. This creates a problem
with which prot ops should be used from the socket closed side.
If the map_free side completes first then we want to call the
original lowest level ops. However, if the tls path runs first
we want to call the sockmap ops. Additionally there was no locking
around prot updates in TLS code paths so the prot ops could
be changed multiple times once from TLS path and again from sockmap
side potentially leaving ops pointed at either TLS or sockmap
when psock and/or tls context have already been destroyed.
To fix this race first only update ops inside callback lock
so that TLS, sockmap and lowest level all agree on prot state.
Second and a ULP callback update() so that lower layers can
inform the upper layer when they are being removed allowing the
upper layer to reset prot ops.
This gets us close to allowing sockmap and tls to be stacked
in arbitrary order but will save that patch for *next trees.
v4:
- make sure we don't free things for device;
- remove the checks which swap the callbacks back
only if TLS is at the top.

__sock_map_delete() may be called from a tcp event such as unhash or
close from the following trace,
tcp_bpf_close()
tcp_bpf_remove()
sk_psock_unlink()
sock_map_delete_from_link()
__sock_map_delete()
In this case the sock lock is held but this only protects against
duplicate removals on the TCP side. If the map is free'd then we have
this trace,
sock_map_free
xchg() <- replaces map entry
sock_map_unref()
sk_psock_put()
sock_map_del_link()
The __sock_map_delete() call however uses a read, test, null over the
map entry which can result in both paths trying to free the map
entry.
To fix use xchg in TCP paths as well so we avoid having two references
to the same map entry.

It is possible (via shutdown()) for TCP socks to go through TCP_CLOSE
state via tcp_disconnect() without actually calling tcp_close which
would then call the tls close callback. Because of this a user could
disconnect a socket then put it in a LISTEN state which would break
our assumptions about sockets always being ESTABLISHED state.
More directly because close() can call unhash() and unhash is
implemented by sockmap if a sockmap socket has TLS enabled we can
incorrectly destroy the psock from unhash() and then call its close
handler again. But because the psock (sockmap socket representation)
is already destroyed we call close handler in sk->prot. However,
in some cases (TLS BASE/BASE case) this will still point at the
sockmap close handler resulting in a circular call and crash reported
by syzbot.
To fix both above issues implement the unhash() routine for TLS.
v4:
- add note about tls offload still needing the fix;
- move sk_proto to the cold cache line;
- split TX context free into "release" and "free",
otherwise the GC work itself is in already freed
memory;
- more TX before RX for consistency;
- reuse tls_ctx_free();
- schedule the GC work after we're done with context
to avoid UAF;
- don't set the unhash in all modes, all modes "inherit"
TLS_BASE's callbacks anyway;
- disable the unhash hook for TLS_HW.

The tls close() callback currently drops the sock lock to call
strp_done(). Split up the RX cleanup into stopping the strparser
and releasing most resources, syncing strparser and finally
freeing the context.
To avoid the need for a strp_done() call on the cleanup path
of device offload make sure we don't arm the strparser until
we are sure init will be successful.

The tls close() callback currently drops the sock lock, makes a
cancel_delayed_work_sync() call, and then relocks the sock.
By restructuring the code we can avoid droping lock and then
reclaiming it. To simplify this we do the following,
tls_sk_proto_close
set_bit(CLOSING)
set_bit(SCHEDULE)
cancel_delay_work_sync() <- cancel workqueue
lock_sock(sk)
...
release_sock(sk)
strp_done()
Setting the CLOSING bit prevents the SCHEDULE bit from being
cleared by any workqueue items e.g. if one happens to be
scheduled and run between when we set SCHEDULE bit and cancel
work. Then because SCHEDULE bit is set now no new work will
be scheduled.

Unfortunately, software context prep includes arming strparser

There is a race between reading task->exit_state in pidfd_poll and
writing it after do_notify_parent calls do_notify_pidfd. Expected
sequence of events is:
CPU 0 CPU 1
------------------------------------------------
exit_notify
do_notify_parent
do_notify_pidfd
tsk->exit_state = EXIT_DEAD
pidfd_poll
if (tsk->exit_state)
However nothing prevents the following sequence:
CPU 0 CPU 1
------------------------------------------------
exit_notify
do_notify_parent
do_notify_pidfd
pidfd_poll
if (tsk->exit_state)
tsk->exit_state = EXIT_DEAD
This causes a polling task to wait forever, since poll blocks because
exit_state is 0 and the waiting task is not notified again. A stress
test continuously doing pidfd poll and process exits uncovered this bug.
To fix it, we make sure that the task's exit_state is always set before
calling do_notify_pidfd.

When a pin is active-low, logical trigger edge should be inverted to match
the same interrupt opportunity.
For example, a button pushed triggers falling edge in ACTIVE_HIGH case; in
ACTIVE_LOW case, the button pushed triggers rising edge. For user space the
IRQ requesting doesn't need to do any modification except to configuring
GPIOHANDLE_REQUEST_ACTIVE_LOW.
For example, we want to catch the event when the button is pushed. The
button on the original board drives level to be low when it is pushed, and
drives level to be high when it is released.
In user space we can do:
req.handleflags = GPIOHANDLE_REQUEST_INPUT;
req.eventflags = GPIOEVENT_REQUEST_FALLING_EDGE;
while (1) {
read(fd, &dat, sizeof(dat));
if (dat.id == GPIOEVENT_EVENT_FALLING_EDGE)
printf("button pushed\n");
}
Run the same logic on another board which the polarity of the button is
inverted; it drives level to be high when pushed, and level to be low when
released. For this inversion we add flag GPIOHANDLE_REQUEST_ACTIVE_LOW:
req.handleflags = GPIOHANDLE_REQUEST_INPUT |
GPIOHANDLE_REQUEST_ACTIVE_LOW;
req.eventflags = GPIOEVENT_REQUEST_FALLING_EDGE;
At the result, there are no any events caught when the button is pushed.
By the way, button releasing will emit a "falling" event. The timing of
"falling" catching is not expected.

While using the mmc_spi driver occasionally errors like this popped up:
mmcblk0: error -84 transferring data end_request: I/O error, dev mmcblk0, sector 581756
I looked on the Internet for occurrences of the same problem and came
across a helpful post [1]. It includes source code to reproduce the bug.
There is also an analysis about the cause. During transmission data in the
supplied buffer is being modified. Thus the previously calculated checksum
is not correct anymore.
After some digging I found out that device drivers are supposed to report
they need stable writes. To fix this I set the appropriate flag at queue
initialization if CRC checksumming is enabled for that SPI host.

In some cases initial bind of scm memory for an lpar can fail if
previously it wasn't released using a scm-unbind hcall. This situation
can arise due to panic of the previous kernel or forced lpar
fadump. In such cases the H_SCM_BIND_MEM return a H_OVERLAP error.
To mitigate such cases the patch updates papr_scm_probe() to force a
call to drc_pmem_unbind() in case the initial bind of scm memory fails
with EBUSY error. In case scm-bind operation again fails after the
forced scm-unbind then we follow the existing error path. We also
update drc_pmem_bind() to handle the H_OVERLAP error returned by phyp
and indicate it as a EBUSY error back to the caller.

The new hcall named H_SCM_UNBIND_ALL has been introduce that can
unbind all or specific scm memory assigned to an lpar. This is
more efficient than using H_SCM_UNBIND_MEM as currently we don't
support partial unbind of scm memory.
Hence this patch proposes following changes to drc_pmem_unbind():
* Update drc_pmem_unbind() to replace hcall H_SCM_UNBIND_MEM to
H_SCM_UNBIND_ALL.
* Update drc_pmem_unbind() to handles cases when PHYP asks the guest
kernel to wait for specific amount of time before retrying the
hcall via the 'LONG_BUSY' return value.
* Ensure appropriate error code is returned back from the function
in case of an error.

In commit 46d179525a1f ("mmc: dw_mmc: Wait for data transfer after
response errors.") we fixed a tuning-induced hang that I saw when
stress testing tuning on certain SD cards. I won't re-hash that whole
commit, but the summary is that as a normal part of tuning you need to
deal with transfer errors and there were cases where these transfer
errors was putting my system into a bad state causing all future
transfers to fail. That commit fixed handling of the transfer errors
for me.
In downstream Chrome OS my fix landed and had the same behavior for
all SD/MMC commands. However, it looks like when the commit landed
upstream we limited it to only SD tuning commands. Presumably this
was to try to get around problems that Alim Akhtar reported on exynos
[1].
Unfortunately while stress testing reboots (and suspend/resume) on
some rk3288-based Chromebooks I found the same problem on the eMMC on
some of my Chromebooks (the ones with Hynix eMMC). Since the eMMC
tuning command is different (MMC_SEND_TUNING_BLOCK_HS200
vs. MMC_SEND_TUNING_BLOCK) we were basically getting back into the
same situation.
I'm hoping that whatever problems exynos was having in the past are
somehow magically fixed now and we can make the behavior the same for
all commands.

When CONFIG_UAPI_HEADER_TEST=y, exported headers are compile-tested to
make sure they can be included from user-space.
Currently, header.h and fw.h are excluded from the test coverage.
To make them join the compile-test, we need to fix the build errors
attached below.
For a case like this, we decided to use __u{8,16,32,64} variable types
in this discussion:
