KVM: s390: bugfix for kvm/master (4.2)
Here is a bugfix for a regression that was introduced after 4.1
with the commit commit 785dbef407d8 ("KVM: s390: optimize round
trip time in request handling"). After lots of cpu hotplugs in the
guest (online/offline) sometimes a guest CPU did loop within host
KVM code. Reason was that PROG_REQUEST was set in the sie control
block, but no request was pending. This made commit 785dbef407d8
the suspect and changing that area to always reset PROG_REQUEST
did indeed fix the problem.
Special thanks to David Hildenbrand, who helped understanding the
exact sequence that led to the problem.
commit 785dbef407d8 ("KVM: s390: optimize round trip time in request
handling") introduced a regression. This regression was seen with
CPU hotplug in the guest and switching between 1 or 2 CPUs. This will
set/reset the IBS control via synced request.
Whenever we make a synced request, we first set the vcpu->requests
bit and then block the vcpu. The handler, on the other hand, unblocks
itself, processes vcpu->requests (by clearing them) and unblocks itself
once again.
Now, if the requester sleeps between setting of vcpu->requests and
blocking, the handler will clear the vcpu->requests bit and try to
unblock itself (although no bit is set). When the requester wakes up,
it blocks the VCPU and we have a blocked VCPU without requests.
Solution is to always unset the block bit.

KEYS: ensure we free the assoc array edit if edit is valid
__key_link_end is not freeing the associated array edit structure
and this leads to a 512 byte memory leak each time an identical
existing key is added with add_key().
The reason the add_key() system call returns okay is that
key_create_or_update() calls __key_link_begin() before checking to see
whether it can update a key directly rather than adding/replacing - which
it turns out it can. Thus __key_link() is not called through
__key_instantiate_and_link() and __key_link_end() must cancel the edit.

arm64/efi: map the entire UEFI vendor string before reading it
At boot, the UTF-16 UEFI vendor string is copied from the system
table into a char array with a size of 100 bytes. However, this
size of 100 bytes is also used for memremapping() the source,
which may not be sufficient if the vendor string exceeds 50
UTF-16 characters, and the placement of the vendor string inside
a 4 KB page happens to leave the end unmapped.
So use the correct '100 * sizeof(efi_char16_t)' for the size of
the mapping.
sunrpc: translate -EAGAIN to -ENOBUFS when socket is writable.
The networking layer does not reliably report the distinction between
a non-block write failing because:
1/ the queue is too full already and
2/ a memory allocation attempt failed.
The distinction is important because in the first case it is
appropriate to retry as soon as the socket reports that it is
writable, and in the second case a small delay is required as the
socket will most likely report as writable but kmalloc could still
fail.
sk_stream_wait_memory() exhibits this distinction nicely, setting
'vm_wait' if a small wait is needed. However in the non-blocking case
it always returns -EAGAIN no matter the cause of the failure. This
-EAGAIN call get all the way to sunrpc.
The sunrpc layer expects EAGAIN to indicate the first cause, and
ENOBUFS to indicate the second. Various documentation suggests that
this is not unreasonable, but does not guarantee the desired error
codes.
The result of getting -EAGAIN when -ENOBUFS is expected is that the
send is tried again in a tight loop and soft lockups are reported.
so: add tests after calls to xs_sendpages() to translate -EAGAIN into
-ENOBUFS if the socket is writable. This cannot happen inside
xs_sendpages() as the test for "is socket writable" is different
between TCP and UDP.
With this change, the tight loop retrying xs_sendpages() becomes a
loop which only retries every 250ms, and so will not trigger a
soft-lockup warning.
It is possible that the write did fail because the queue was too full
and by the time xs_sendpages() completed, the queue was writable
again. In this case an extra 250ms delay is inserted that isn't
really needed. This circumstance suggests a degree of congestion so a
delay is not necessarily a bad thing, and it can only cause a single
250ms delay, not a series of them.

libnvdimm: fix namespace seed creation
A new BLK namespace "seed" device is created whenever the current seed
is successfully probed. However, if that namespace is assigned to a BTT
it may never directly experience a successful probe as it is a
subordinate device to a BTT configuration.
The effect of the current code is that no new namespaces can be
instantiated, after the seed namespace, to consume available BLK DPA
capacity. Fix this by treating a successful BTT probe event as a
successful probe event for the backing namespace.

to the set_ftrace_pid file.
Add back the proper hooks to have pid filtering working once again.

The touchscreen on the WinBook TW100 and TW700 don't match the default

It's unfortunately impossible to detect this problem with data from the
DSDT, or other auxiliary metadata, so fallback to quirking this specific

Devices may declare more LEDs than what is known to input-leds

ignore LEDs that are not known to us.

mmc: sdhci-pxav3: fix platform_data is not initialized
pdev->dev.platform_data is not initialized if match is true in function
sdhci_pxav3_probe. Just local variable pdata is assigned the return value
from function pxav3_get_mmc_pdata().
static int sdhci_pxav3_probe(struct platform_device *pdev) {
struct sdhci_pxa_platdata *pdata = pdev->dev.platform_data;

ret = mmc_of_parse(host->mmc);
if (ret)
goto err_of_parse;
sdhci_get_of_property(pdev);
pdata = pxav3_get_mmc_pdata(dev);
}
...
}
After commit 8d86e4fcccf6 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()"),
we do not need those duplicated parsing anymore.
Note: fsl,cd-controller is also deleted due to the driver does
not support controller card detection anymore after switch to runtime pm.
And there's no user of it right now in device tree.
wp-gpios is kept because we're still support fsl,wp-controller,
so we need a way to check if it's gpio wp or controller wp.
mmc: sdhci: make max-frequency property in device tree work
Device tree provides option to specify the max freqency with property
"max-frequency" in dts and common parse function mmc_of_parse() will
parse it and use this value to set host->f_max to tell the MMC core
the maxinum frequency the host works.
However, current sdhci driver will finally overwrite this value with
host->max_clk regardless of the max-frequency property.
This patch makes sure not overwrite the max-frequency set from device
tree and do basic sanity check.
mmc: sdhci-esdhc-imx: move all non dt probe code into one function
This is an incremental fix of commit e62bd351b("mmc: sdhci-esdhc-imx: Do not break platform data boards").
After commit 8d86e4fcccf6 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()"),
we do not need to run the check of boarddata->wp_type/cd_type/max_bus_width
again for dt platform since those are already handled by mmc_of_parse().
Current code only exclude the checking of wp_type for dt platform which
does not make sense.
This patch moves all non dt probe code into one function.
Besides, since we only support SD3.0/eMMC HS200 for dt platform, the
support_vsel checking and ultra high speed pinctrl state are also merged
into sdhci_esdhc_imx_probe_dt.
Then we have two separately probe function for dt and non dt type.
This can make the driver probe more clearly.
mmc: sdhci-esdhc-imx: fix cd regression for dt platform
Current card detect probe process is that when driver finds a valid
ESDHC_CD_GPIO, it will clear the quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION
which is set by default for all esdhc/usdhc controllers.
Then host driver will know there's a valid card detect function.
Commit 8d86e4fcccf6 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()")
breaks GPIO CD function for dt platform that it will return directly
when find ESDHC_CD_GPIO for dt platform which result in the later wrongly
to keep SDHCI_QUIRK_BROKEN_CARD_DETECTION for all dt platforms.
Then MMC_CAP_NEEDS_POLL will be used instead even there's a valid
GPIO card detect.
This patch adds back this function and follows the original approach to
clear the quirk if find an valid CD GPIO for dt platforms.

Sometimes BADA, DEB or CEB error interrupts occur when sd card is

DTO/DCRC errors were not being informed to the mmc core since
commit ae4bf788ee9b ("mmc: omap_hsmmc: consolidate error report handling of
HSMMC IRQ"). This commit made sure 'end_trans' is never set on DTO/DCRC
errors. This is because after this commit 'host->data' is checked after
it has been cleared to NULL by omap_hsmmc_dma_cleanup().
Because 'end_trans' is never set, omap_hsmmc_xfer_done() is never invoked
making core layer not to be aware of DTO/DCRC errors. Because of this
any command invoked after DTO/DCRC error leads to a hang.
Fix this by checking for 'host->data' before it is actually cleared.

During a node failure, We need to suspend read balancing so that the
reads are directed to the first device and stale data is not read.
Suspending writes is not required because these would be recorded and
synced eventually.
A new flag MD_CLUSTER_SUSPEND_READ_BALANCING is set in recover_prep().
area_resyncing() will respond true for the entire devices if this
flag is set and the request type is READ. The flag is cleared
in recover_done().
md-cluster: fix bitmap sub-offset in bitmap_read_sb
bitmap_read_sb is modifying mddev->bitmap_info.offset. This works for
the first bitmap read. However, when multiple bitmaps need to be opened
by the same node, it ends up corrupting the offset. Fix it by using a
local variable.
Also, bitmap_read_sb is not required in bitmap_copy_from_slot since
it is called in bitmap_create. Remove bitmap_read_sb().
md: Return error if request_module fails and returns positive value
request_module() can return 256 (process exited) in some cases,
which is not as specified in the documentation before the
request_module() definition. Convert the error to -ENOENT.
The positive error number results in bitmap_create() returning
a value that is meant to be an error but doesn't look like one,
so it is dereferenced as a point and causes a crash.

md/raid1: fix test for 'was read error from last working device'.
When we get a read error from the last working device, we don't
try to repair it, and don't fail the device. We simple report a
read error to the caller.
However the current test for 'is this the last working device' is
wrong.
When there is only one fully working device, it assumes that a
non-faulty device is that device. However a spare which is rebuilding
would be non-faulty but so not the only working device.
So change the test from "!Faulty" to "In_sync". If ->degraded says
there is only one fully working device and this device is in_sync,
this must be the one.
This bug has existed since we allowed read_balance to read from
a recovering spare in v3.0

serial: core: Fix crashes while echoing when closing
While closing, new rx data may be received after the input buffers

new data might not be processed by flush_to_ldisc() until after
uart_shutdown() and normal input processing is re-enabled (ie.,

Input processing must be prevented from echoing (tty->closing = 1)
until _after_ the input buffers have been flushed again at the end

[1] In fact, some input may actually be buffered _after_ stop_rx()
