[PATCH AUTOSEL 5.4 01/32] ARM: dts: rockchip: fix phy nodename for rk3228-evb

[Sasha Levin]

From: Johan Jonker <jbx6244@gmail.com>

[ Upstream commit 287e0d538fcec2f6e8eb1e565bf0749f3b90186d ]

A test with the command below gives for example this error:

arch/arm/boot/dts/rk3228-evb.dt.yaml: phy@0:
'#phy-cells' is a required property

The phy nodename is normally used by a phy-handle.
This node is however compatible with
"ethernet-phy-id1234.d400", "ethernet-phy-ieee802.3-c22"
which is just been added to 'ethernet-phy.yaml'.
So change nodename to 'ethernet-phy' for which '#phy-cells'
is not a required property

[PATCH AUTOSEL 5.4 05/32] ARM: dts: rockchip: swap clock-names of gpu nodes

[Sasha Levin]

From: Johan Jonker <jbx6244@gmail.com>

[ Upstream commit b14f3898d2c25a9b47a61fb879d0b1f3af92c59b ]

Dts files with Rockchip 'gpu' nodes were manually verified.
In order to automate this process arm,mali-utgard.txt
has been converted to yaml. In the new setup dtbs_check with
arm,mali-utgard.yaml expects clock-names values
in the same order, so fix that.

[PATCH AUTOSEL 5.4 07/32] gpio: tegra: mask GPIO IRQs during IRQ shutdown

[Sasha Levin]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

[ Upstream commit 0cf253eed5d2bdf7bb3152457b38f39b012955f7 ]

The driver currently leaves GPIO IRQs unmasked even when the GPIO IRQ
client has released the GPIO IRQ. This allows the HW to raise IRQs, and
SW to process them, after shutdown. Fix this by masking the IRQ when it's
shut down. This is usually taken care of by the irqchip core, but since
this driver has a custom irq_shutdown implementation, it must do this
explicitly itself.

[PATCH AUTOSEL 5.4 08/32] ALSA: usb-audio: add mapping for ASRock TRX40 Creator

[Sasha Levin]

From: Andrew Oakley <andrew@adoakley.name>

[ Upstream commit da7a8f1a8fc3e14c6dcc52b4098bddb8f20390be ]

This is another TRX40 based motherboard with ALC1220-VB USB-audio
that requires a static mapping table.

This motherboard also has a PCI device which advertises no codecs.  The
PCI ID is 1022:1487 and PCI SSID is 1022:d102.  As this is using the AMD
vendor ID, don't blacklist for now in case other boards have a working
audio device with the same ssid.

alsa-info.sh report for this board:

[PATCH AUTOSEL 5.4 08/32] ALSA: usb-audio: add mapping for ASRock TRX40 Creator

[Sasha Levin]

From: Andrew Oakley <andrew@adoakley.name>

[ Upstream commit da7a8f1a8fc3e14c6dcc52b4098bddb8f20390be ]

This is another TRX40 based motherboard with ALC1220-VB USB-audio
that requires a static mapping table.

This motherboard also has a PCI device which advertises no codecs.  The
PCI ID is 1022:1487 and PCI SSID is 1022:d102.  As this is using the AMD
vendor ID, don't blacklist for now in case other boards have a working
audio device with the same ssid.

alsa-info.sh report for this board:
http://alsa-project.org/db/?f=0a742f89066527497b77ce16bca486daccf8a70c

[PATCH AUTOSEL 5.4 09/32] net: microchip: encx24j600: add missed kthread_stop

[Sasha Levin]

From: Chuhong Yuan <hslester96@gmail.com>

[ Upstream commit ff8ce319e9c25e920d994cc35236f0bb32dfc8f3 ]

This driver calls kthread_run() in probe, but forgets to call
kthread_stop() in probe failure and remove.
Add the missed kthread_stop() to fix it.

[PATCH AUTOSEL 5.4 10/32] gfs2: move privileged user check to gfs2_quota_lock_check

[Sasha Levin]

From: Bob Peterson <rpeterso@redhat.com>

[ Upstream commit 4ed0c30811cb4d30ef89850b787a53a84d5d2bcb ]

Before this patch, function gfs2_quota_lock checked if it was called
from a privileged user, and if so, it bypassed the quota check:
superuser can operate outside the quotas.
That's the wrong place for the check because the lock/unlock functions
are separate from the lock_check function, and you can do lock and
unlock without actually checking the quotas.

This patch moves the check to gfs2_quota_lock_check.

gfs2_quota_unhold. With the new system of gfs2_qa_get and put, we
no longer want to call gfs2_quota_unhold or we won't balance our

[PATCH AUTOSEL 5.4 15/32] drm/amdgpu: Use GEM obj reference for KFD BOs

[Sasha Levin]

From: Felix Kuehling <Felix.Kuehling@amd.com>

[ Upstream commit 39b3128d7ffd44e400e581e6f49e88cb42bef9a1 ]

Releasing the AMDGPU BO ref directly leads to problems when BOs were
exported as DMA bufs. Releasing the GEM reference makes sure that the
AMDGPU/TTM BO is not freed too early.

Also take a GEM reference when importing BOs from DMABufs to keep
references to imported BOs balances properly.

[PATCH AUTOSEL 5.4 16/32] Revert "gfs2: Don't demote a glock until its revokes are written"

[Sasha Levin]

From: Bob Peterson <rpeterso@redhat.com>

[ Upstream commit b14c94908b1b884276a6608dea3d0b1b510338b7 ]

This reverts commit df5db5f9ee112e76b5202fbc331f990a0fc316d6.

This patch fixes a regression: patch df5db5f9ee112 allowed function
run_queue() to bypass its call to do_xmote() if revokes were queued for
the glock. That's wrong because its call to do_xmote() is what is
responsible for calling the go_sync() glops functions to sync both
the ail list and any revokes queued for it. By bypassing the call,
gfs2 could get into a stand-off where the glock could not be demoted
until its revokes are written back, but the revokes would not be
written back because do_xmote() was never called.

It "sort of" works, however, because there are other mechanisms like
the log flush daemon (logd) that can sync the ail items and revokes,
if it deems it necessary. The problem is: without file system pressure,
it might never deem it necessary.

[PATCH AUTOSEL 5.4 17/32] cachefiles: Fix race between read_waiter and read_copier involving op->to_do

[Sasha Levin]

From: Lei Xue <carmark.dlut@gmail.com>

[ Upstream commit 7bb0c5338436dae953622470d52689265867f032 ]

There is a potential race in fscache operation enqueuing for reading and
copying multiple pages from cachefiles to netfs.  The problem can be seen
easily on a heavy loaded system (for example many processes reading files
continually on an NFS share covered by fscache triggered this problem within
a few minutes).

The race is due to cachefiles_read_waiter() adding the op to the monitor
to_do list and then then drop the object->work_lock spinlock before
completing fscache_enqueue_operation().  Once the lock is dropped,
cachefiles_read_copier() grabs the op, completes processing it, and
makes it through fscache_retrieval_complete() which sets the op->state to
the final state of FSCACHE_OP_ST_COMPLETE(4).  When cachefiles_read_waiter()
finally gets through the remainder of fscache_enqueue_operation()
it sees the invalid state, and hits the ASSERTCMP and the following
oops is seen:

[PATCH AUTOSEL 5.4 18/32] usb: dwc3: pci: Enable extcon driver for Intel Merrifield

[Sasha Levin]

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

[ Upstream commit 066c09593454e89bc605ffdff1c9810061f9b1e1 ]

Intel Merrifield provides a DR support via PMIC which has its own
extcon driver.

Add a property string to link to that driver.

[PATCH AUTOSEL 5.4 19/32] usb: phy: twl6030-usb: Fix a resource leak in an error handling path in 'twl6030_usb_probe()'

[Sasha Levin]

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit f058764d19000d98aef72010468db1f69faf9fa0 ]

A call to 'regulator_get()' is hidden in 'twl6030_usb_ldo_init()'. A
corresponding put must be performed in the error handling path, as
already done in the remove function.

While at it, also move a 'free_irq()' call in the error handling path in
order to be consistent.

[PATCH AUTOSEL 5.4 21/32] net: freescale: select CONFIG_FIXED_PHY where needed

[Sasha Levin]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 99352c79af3e5f2e4724abf37fa5a2a3299b1c81 ]

I ran into a randconfig build failure with CONFIG_FIXED_PHY=m
and CONFIG_GIANFAR=y:

x86_64-linux-ld: drivers/net/ethernet/freescale/gianfar.o:(.rodata+0x418): undefined reference to `fixed_phy_change_carrier'

It seems the same thing can happen with dpaa and ucc_geth, so change
all three to do an explicit 'select FIXED_PHY'.

The fixed-phy driver actually has an alternative stub function that
theoretically allows building network drivers when fixed-phy is
disabled, but I don't see how that would help here, as the drivers
presumably would not work then.

From: Tero Kristo <t-kristo@ti.com>

[ Upstream commit dc6dbd51009fc412729c307161f442c0a08618f4 ]

Right now, trying to use RTC purely with the ti-sysc / clkctrl framework
fails to enable the RTC module properly. Based on experimentation, this
appears to be because RTC is sourced from the clkdiv32k optional clock.
TRM is not very clear on this topic, but fix the RTC to use the proper
source clock nevertheless.

[PATCH AUTOSEL 5.4 30/32] csky: Fixup raw_copy_from_user()

[Sasha Levin]

From: Al Viro <viro@zeniv.linux.org.uk>

[ Upstream commit 51bb38cb78363fdad1f89e87357b7bc73e39ba88 ]

If raw_copy_from_user(to, from, N) returns K, callers expect
the first N - K bytes starting at to to have been replaced with
the contents of corresponding area starting at from and the last
K bytes of destination *left* *unmodified*.

What arch/sky/lib/usercopy.c is doing is broken - it can lead to e.g.
data corruption on write(2).

raw_copy_to_user() is inaccurate about return value, which is a bug,
but consequences are less drastic than for raw_copy_from_user().
And just what are those access_ok() doing in there?  I mean, look into
linux/uaccess.h; that's where we do that check (as well as zero tail
on failure in the callers that need zeroing).

AFAICS, all of that shouldn't be hard to fix; something like a patch
below might make a useful starting point.

I would suggest moving these macros into usercopy.c (they are never
used anywhere else) and possibly expanding them there; if you leave
them alive, please at least rename __copy_user_zeroing(). Again,
it must not zero anything on failed read.

Said that, I'm not sure we won't be better off simply turning
usercopy.c into usercopy.S - all that is left there is a couple of
functions, each consisting only of inline asm.

Guo Ren reply:

Yes, raw_copy_from_user is wrong, it's no need zeroing code.

unsigned long _copy_from_user(void *to, const void __user *from,
unsigned long n)
{
        unsigned long res = n;
        might_fault();
        if (likely(access_ok(from, n))) {
                kasan_check_write(to, n);
                res = raw_copy_from_user(to, from, n);
        }
        if (unlikely(res))
                memset(to + (n - res), 0, res);
        return res;
}
EXPORT_SYMBOL(_copy_from_user);

You are right and access_ok() should be removed.

but, how about:
do {
...
        "2:     stw     %3, (%1, 0)     \n"             \
+       "       subi    %0, 4          \n"               \
        "9:     stw     %4, (%1, 4)     \n"             \
+       "       subi    %0, 4          \n"               \
        "10:    stw     %5, (%1, 8)     \n"             \
+       "       subi    %0, 4          \n"               \
        "11:    stw     %6, (%1, 12)    \n"             \
+       "       subi    %0, 4          \n"               \
        "       addi    %2, 16          \n"             \
        "       addi    %1, 16          \n"             \

Don't expand __ex_table

AI Viro reply:

Hey, I've no idea about the instruction scheduling on csky -
if that doesn't slow the things down, all the better.  It's just
that copy_to_user() and friends are on fairly hot codepaths,
and in quite a few situations they will dominate the speed of
e.g. read(2).  So I tried to keep the fast path unchanged.
Up to the architecture maintainers, obviously.  Which would be
you...

As for the fixups size increase (__ex_table size is unchanged)...
You have each of those macros expanded exactly once.
So the size is not a serious argument, IMO - useless complexity
would be, if it is, in fact, useless; the size... not really,
especially since those extra subi will at least offset it.

Again, up to you - asm optimizations of (essentially)
memcpy()-style loops are tricky and can depend upon the
fairly subtle details of architecture.  So even on something
I know reasonably well I would resort to direct experiments
if I can't pass the buck to architecture maintainers.

It *is* worth optimizing - this is where read() from a file
that is already in page cache spends most of the time, etc.

Guo Ren reply:

Thx, after fixup some typo “sub %0, 4”, apply the patch.

TODO:
 - user copy/from codes are still need optimizing.

[PATCH AUTOSEL 5.4 31/32] samples: bpf: Fix build error

[Sasha Levin]

From: Matteo Croce <mcroce@redhat.com>

[ Upstream commit 23ad04669f81f958e9a4121b0266228d2eb3c357 ]

GCC 10 is very strict about symbol clash, and lwt_len_hist_user contains
a symbol which clashes with libbpf:

/usr/bin/ld: samples/bpf/lwt_len_hist_user.o:(.bss+0x0): multiple definition of `bpf_log_buf'; samples/bpf/bpf_load.o:(.bss+0x8c0): first defined here
collect2: error: ld returned 1 exit status

bpf_log_buf here seems to be a leftover, so removing it.
