Merge tag 'io_uring-5.8-2020-07-01' of git://git.kernel.dk/linux-block
Pull io_uring fixes from Jens Axboe:
"One fix in here, for a regression in 5.7 where a task is waiting in
the kernel for a condition, but that condition won't become true until
task_work is run. And the task_work can't be run exactly because the
task is waiting in the kernel, so we'll never make any progress.
One example of that is registering an eventfd and queueing io_uring
work, and then the task goes and waits in eventfd read with the
expectation that it'll get woken (and read an event) when the io_uring
request completes. The io_uring request is finished through task_work,
which won't get run while the task is looping in eventfd read"

"Include PCRs 8 & 9 in per TPM 2.0 bank boot_aggregate calculation.
Prior to Linux 5.8 the SHA1 "boot_aggregate" value was padded with 0's
and extended into the other TPM 2.0 banks.
Included in the Linux 5.8 open window, TPM 2.0 PCR bank specific
"boot_aggregate" values (PCRs 0 - 7) are calculated and extended into the TPM banks.
Distro releases are now shipping grub2 with TPM support, which extend
PCRs 8 & 9. I'd like for PCRs 8 & 9 to be included in the new
"boot_aggregate" calculations.
For backwards compatibility, if the hash is SHA1, these new PCRs are
not included in the boot aggregate"

ima: extend boot_aggregate with kernel measurements
Since 5.7, we've been using task_work to trigger async running of
requests in the context of the original task. This generally works
great, but there's a case where if the task is currently blocked
in the kernel waiting on a condition to become true, it won't process
task_work. Even though the task is woken, it just checks whatever
condition it's waiting on, and goes back to sleep if it's still false.
This is a problem if that very condition only becomes true when that
task_work is run. An example of that is the task registering an eventfd
with io_uring, and it's now blocked waiting on an eventfd read. That
read could depend on a completion event, and that completion event
won't get trigged until task_work has been run.
Use the TWA_SIGNAL notification for task_work, so that we ensure that
the task always runs the work when queued.

So that the target task will exit the wait_event_interruptible-like
loop and call task_work_run() asap.
The patch turns "bool notify" into 0,TWA_RESUME,TWA_SIGNAL enum, the
new TWA_SIGNAL flag implies signal_wake_up(). However, it needs to
avoid the race with recalc_sigpending(), so the patch also adds the
new JOBCTL_TASK_WORK bit included in JOBCTL_PENDING_MASK.
TODO: once this patch is merged we need to change all current users
of task_work_add(notify = true) to use TWA_RESUME.

fsnotify-related overhead for pseudo inodes but it is broken in
concept. inotify can receive events of pipe files under /proc/X/fd and
chromium relies on close and open events for sandboxing. Maxim Levitsky
reported the following
Chromium starts as a white rectangle, shows few white rectangles that

Crashes are not universal but even if chromium does not crash, it certainly

When the kernel panics, one page of kmsg data may be collected and sent to
Hyper-V to aid in diagnosing the failure. The collected kmsg data typically
contains 50 to 100 lines, each of which has a log level prefix that isn't
very useful from a diagnostic standpoint. So tell kmsg_dump_get_buffer()
to not include the log level, enabling more information that *is* useful to
fit in the page.

As description for DIV_ROUND_CLOSEST in file include/linux/kernel.h.
"Result is undefined for negative divisors if the dividend variable
type is unsigned and for negative dividends if the divisor variable
type is unsigned."
In current code, the FIXPT_DIV uses DIV_ROUND_CLOSEST but has not
checked sign of divisor before using. It makes undefined temperature
value in case the value is negative.
This patch fixes to satisfy DIV_ROUND_CLOSEST description
and fix bug too. Note that the variable name "reg" is not good
because it should be the same type as rcar_gen3_thermal_read().
However, it's better to rename the "reg" in a further patch as
cleanup.

generic_file_fsync() exfat used could not guarantee the consistency of
a file because it has flushed not dirty metadata but only dirty data pages
for a file.
Instead of that, use exfat_file_fsync() for files and directories so that
it guarantees to commit both the metadata and data pages for a file.

We need to commit dirty metadata and pages to disk
before remounting exfat as read-only.
This fixes a failure in xfstests generic/452
generic/452 does the following:
cp something <exfat>/
mount -o remount,ro <exfat>
the <exfat>/something is corrupted. because while
exfat is remounted as read-only, exfat doesn't
have a chance to commit metadata and
vfs invalidates page caches in a block device.

If the second exfat_get_dentry() call fails then we need to release
"old_bh" before returning. There is a similar bug in exfat_move_file().

Some fsck tool complain that padding part of the FileName field

The OMAP developers are particularly active at hunting down regressions,
so this is a separate branch with OMAP specific fixes for the v5.8:
As Tony explains
"The recent display subsystem (DSS) related platform data changes
caused display related regressions for suspend and resume. Looks like
I only tested suspend and resume before dropping the legacy platform
data, and forgot to test it after dropping it. Turns out the main issue
was that we no longer have platform code calling pm_runtime_suspend
for DSS like we did for the legacy platform data case, and that fix
is still being discussed on the dri-devel list and will get merged
separately. The DSS related testing exposed a pile other other display
related issues that also need fixing though":
- Fix ti-sysc optional clock handling and reset status checks
for devices that reset automatically in idle like DSS
- Ignore ti-sysc clockactivity bit unless separately requested
to avoid unexpected performance issues
- Init ti-sysc framedonetv_irq to true and disable for am4
- Avoid duplicate DSS reset for legacy mode with dts data
- Remove LCD timings for am4 as they cause warnings now that we're
using generic panels
Other OMAP changes from Tony include:
- Fix omap_prm reset deassert as we still have drivers setting the
pm_runtime_irq_safe() flag
- Flush posted write for ti-sysc enable and disable
- Fix droid4 spi related errors with spi flags
- Fix am335x USB range and a typo for softreset
- Fix dra7 timer nodes for clocks for IPU and DSP
- Drop duplicate mailboxes after mismerge for dra7
- Prevent pocketgeagle header line signal from accidentally setting
micro-SD write protection signal by removing the default mux
- Fix NFSroot flakeyness after resume for duover by switching the
smsc911x gpio interrupt to back to level sensitive
- Fix regression for omap4 clockevent source after recent system
timer changes
- Yet another ethernet regression fix for the "rgmii" vs "rgmii-rxid"
phy-mode
- One patch to convert am3/am4 DT files to use the regular sdhci-omap
driver instead of the old hsmmc driver, this was meant for the
merge window but got lost in the process.

A single commit that uses "arch_" atomic operations to avoid the
instrumentation that comes with the non-"arch_" versions. In preparation
for that commit, it also has another commit that makes these "arch_"
atomic operations available to generic code.
Without these commits, KCSAN uses can see pointless errors.
Both from Peter Zijlstra.

Some performance regression on reaim benchmark have been raised with
commit 070f5e860ee2 ("sched/fair: Take into account runnable_avg to classify group")
The problem comes from the init value of runnable_avg which is initialized
with max value. This can be a problem if the newly forked task is finally
a short task because the group of CPUs is wrongly set to overloaded and
tasks are pulled less agressively.
Set initial value of runnable_avg equals to util_avg to reflect that there
is no waiting time so far.

Paul reported rcutorture occasionally hitting a NULL deref:
sched_ttwu_pending()
ttwu_do_wakeup()
check_preempt_curr() := check_preempt_wakeup()
find_matching_se()
is_same_group()
if (se->cfs_rq == pse->cfs_rq) <-- *BOOM*
Debugging showed that this only appears to happen when we take the new
code-path from commit:
2ebb17717550 ("sched/core: Offload wakee task activation if it the wakee is descheduling")
and only when @cpu == smp_processor_id(). Something which should not
be possible, because p->on_cpu can only be true for remote tasks.
Similarly, without the new code-path from commit:
c6e7bd7afaeb ("sched/core: Optimize ttwu() spinning on p->on_cpu")
this would've unconditionally hit:
smp_cond_load_acquire(&p->on_cpu, !VAL);
and if: 'cpu == smp_processor_id() && p->on_cpu' is possible, this
would result in an instant live-lock (with IRQs disabled), something
that hasn't been reported.
The NULL deref can be explained however if the task_cpu(p) load at the
beginning of try_to_wake_up() returns an old value, and this old value
happens to be smp_processor_id(). Further assume that the p->on_cpu
load accurately returns 1, it really is still running, just not here.
Then, when we enqueue the task locally, we can crash in exactly the
observed manner because p->se.cfs_rq != rq->cfs_rq, because p's cfs_rq
is from the wrong CPU, therefore we'll iterate into the non-existant
parents and NULL deref.
The closest semi-plausible scenario I've managed to contrive is
somewhat elaborate (then again, actual reproduction takes many CPU
hours of rcutorture, so it can't be anything obvious):
X->cpu = 1
rq(1)->curr = X
CPU0 CPU1 CPU2
// switch away from X
LOCK rq(1)->lock
smp_mb__after_spinlock
dequeue_task(X)
X->on_rq = 9
switch_to(Z)
X->on_cpu = 0
UNLOCK rq(1)->lock
// migrate X to cpu 0
LOCK rq(1)->lock
dequeue_task(X)
set_task_cpu(X, 0)
X->cpu = 0
UNLOCK rq(1)->lock
LOCK rq(0)->lock
enqueue_task(X)
X->on_rq = 1
UNLOCK rq(0)->lock
// switch to X
LOCK rq(0)->lock
smp_mb__after_spinlock
switch_to(X)
X->on_cpu = 1
UNLOCK rq(0)->lock
// X goes sleep
X->state = TASK_UNINTERRUPTIBLE
smp_mb(); // wake X
ttwu()
LOCK X->pi_lock
smp_mb__after_spinlock
if (p->state)
cpu = X->cpu; // =? 1
smp_rmb()
// X calls schedule()
LOCK rq(0)->lock
smp_mb__after_spinlock
dequeue_task(X)
X->on_rq = 0
if (p->on_rq)
smp_rmb();
if (p->on_cpu && ttwu_queue_wakelist(..)) [*]
smp_cond_load_acquire(&p->on_cpu, !VAL)
cpu = select_task_rq(X, X->wake_cpu, ...)
if (X->cpu != cpu)
switch_to(Y)
X->on_cpu = 0
UNLOCK rq(0)->lock
However I'm having trouble convincing myself that's actually possible
on x86_64 -- after all, every LOCK implies an smp_mb() there, so if ttwu
observes ->state != RUNNING, it must also observe ->cpu != 1.
(Most of the previous ttwu() races were found on very large PowerPC)
Nevertheless, this fully explains the observed failure case.
Fix it by ordering the task_cpu(p) load after the p->on_cpu load,
which is easy since nothing actually uses @cpu before this.

syzbot reported the following warning:
WARNING: CPU: 1 PID: 6351 at kernel/sched/deadline.c:628
enqueue_task_dl+0x22da/0x38a0 kernel/sched/deadline.c:1504
At deadline.c:628 we have:
623 static inline void setup_new_dl_entity(struct sched_dl_entity *dl_se)
624 {
625 struct dl_rq *dl_rq = dl_rq_of_se(dl_se);
626 struct rq *rq = rq_of_dl_rq(dl_rq);
627
628 WARN_ON(dl_se->dl_boosted);
629 WARN_ON(dl_time_before(rq_clock(rq), dl_se->deadline));
[...]
}
Which means that setup_new_dl_entity() has been called on a task
currently boosted. This shouldn't happen though, as setup_new_dl_entity()
is only called when the 'dynamic' deadline of the new entity
is in the past w.r.t. rq_clock and boosted tasks shouldn't verify this
condition.
Digging through the PI code I noticed that what above might in fact happen
if an RT tasks blocks on an rt_mutex hold by a DEADLINE task. In the
first branch of boosting conditions we check only if a pi_task 'dynamic'
deadline is earlier than mutex holder's and in this case we set mutex
holder to be dl_boosted. However, since RT 'dynamic' deadlines are only
initialized if such tasks get boosted at some point (or if they become
DEADLINE of course), in general RT 'dynamic' deadlines are usually equal
to 0 and this verifies the aforementioned condition.
Fix it by checking that the potential donor task is actually (even if
temporary because in turn boosted) running at DEADLINE priority before
using its 'dynamic' deadline value.

5.8, please pull the following:
- Rafal adds a missing 'device_type' property to the Luxul XWC-2000
required for the memory nodes to be correctly parsed by Linux
- Matthew provides two fixes for the NSP SoCs, one to disable the PL330
DMA controller by default since it can be left in reset by the
bootloader and the second to correct the flow accelerator mailbox node

This reverts commit 7b8e0188fa717cd9abc4fb52587445b421835c2a.
Initially, STiH410-B2260 was supposed to be secured, that's why
l2c_write_sec was stubbed to avoid secure register access from
non secure world.
But by default, STiH410-B2260 is running in non secure mode,
so L2 cache register accesses are authorized, l2c_write_sec stub
is not needed.
With this patch, L2 cache is configured and performance are enhanced.

Few fixes for various devices:
- Prevent pocketgeagle header line signal from accidentally setting
micro-SD write protection signal by removing the default mux
- Fix NFSroot flakeyness after resume for duover by switching the
smsc911x gpio interrupt to back to level sensitive
- Fix regression for omap4 clockevent source after recent system
timer changes
- Yet another ethernet regression fix for the "rgmii" vs "rgmii-rxid"

I forgot to send a pull request earlier for converting am3 and am4 to
use sdhci-omap driver instead of the old omap_hsmmc driver.
There was a display subsystem related suspend and resume regression found
recently and looks like I forgot to send a pull request for this patch
while debugging the regression. This patch has been tested without the
display subsystem, and has been in Linux next for several weeks now, so
would be good to have merged for v5.8.
