The driver checks that the number of retries made by the device is
coherent with the rate policy. However, this check make sense only if
the device has returned RETRY_EXCEEDED.

When not using HT mode, minstrel always includes 1Mbps as fallback rate.
But, when using HT mode, this fallback is not included. Yet, it seems
that it could save some frames. So, this patch add it unconditionally.

A tx_retry_policy (the equivalent of a list of ieee80211_tx_rate in
hardware API) is not able to include a rate multiple time. So currently,
the driver merges the identical rates from the policy provided by
minstrel (and it try to do the best choice it can in the associated
flags) before to sent it to firmware.
Until now, when rates are merged, field "count" is set to
max(count1, count2). But, it means that the sum of retries for all rates
could be far less than initial number of retries. So, this patch changes
the value of field "count" to count1 + count2. Thus, sum of all retries
for all rates stay the same.

In some rare cases, driver may not have any available tx_retry_policies.
In this case, the driver asks to mac80211 to stop sending data. However,
it seems that a race is possible and a few frames can be sent to the
driver. In this case, driver can't wait for free tx_retry_policies since
wfx_tx() must be atomic. So, this patch fix this case by sending these
frames with the special policy number 15.
The firmware normally use policy 15 to send internal frames (PS-poll,
beacons, etc...). So, it is not a so bad fallback.

Device and driver maintain a cache of rate policies (aka.
tx_retry_policy in hardware API).
When hif_reset() is sent to hardware, device resets its cache of rate
policies. In order to keep driver in sync, it is necessary to do the
same on driver.
Note, when driver tries to use a rate policy that has not been defined
on device, data is sent at 1Mbps. So, this patch should fix abnormal
throughput observed sometime after a reset of the interface.

Since commit 0a432dcbeb32 ("mm: shrinker: make shrinker not depend on
memcg kmem"), shrinkers' idr is protected by CONFIG_MEMCG instead of
CONFIG_MEMCG_KMEM, so it makes no sense to protect shrinker idr replace
with CONFIG_MEMCG_KMEM.
And in the CONFIG_MEMCG && CONFIG_SLOB case, shrinker_idr contains only
shrinker, and it is deferred_split_shrinker. But it is never actually
called, since idr_replace() is never compiled due to the wrong #ifdef.
The deferred_split_shrinker all the time is staying in half-registered
state, and it's never called for subordinate mem cgroups.

syzkaller and the fault injector showed that I was wrong to assume that
we could ignore percpu shadow allocation failures.
Handle failures properly. Merge all the allocated areas back into the
free list and release the shadow, then clean up and return NULL. The
shadow is released unconditionally, which relies upon the fact that the
release function is able to tolerate pages not being present.
Also clean up shadows in the recovery path - currently they are not
released, which leaks a bit of memory.

kasan_release_vmalloc uses apply_to_page_range to release vmalloc
shadow. Unfortunately, apply_to_page_range can allocate memory to fill

apply_to_page_range() takes an address range, and if any parts of it are
not covered by the existing page table hierarchy, it allocates memory to
fill them in.
In some use cases, this is not what we want - we want to be able to
operate exclusively on PTEs that are already in the tables.
Add apply_to_existing_page_range() for this. Adjust the walker
functions for apply_to_page_range to take 'create', which switches them
between the old and new modes.
This will be used in KASAN vmalloc.

With CONFIG_KASAN_VMALLOC=y any use of memory obtained via vm_map_ram()
will crash because there is no shadow backing that memory.
Instead of sprinkling additional kasan_populate_vmalloc() calls all over
the vmalloc code, move it into alloc_vmap_area(). This will fix
vm_map_ram() and simplify the code a bit.

The comment says "this should never fail", but it definitely can fail
when you have odd initial boot filesystems, or kernel configurations.
So get the error handling right: filp_open() returns an error pointer.

If a transaction error happens in vhci_recv_ret_submit(), event
handler closes connection and changes port status to kick hub_event.
Then hub tries to flush the endpoint URBs, but that causes infinite
loop between usb_hub_flush_endpoint() and vhci_urb_dequeue() because
"vhci_priv" in vhci_urb_dequeue() was already released by
vhci_recv_ret_submit() before a transmission error occurred. Thus,
vhci_urb_dequeue() terminates early and usb_hub_flush_endpoint()
continuously calls vhci_urb_dequeue().
The root cause of this issue is that vhci_recv_ret_submit()
terminates early without giving back URB when transaction error
occurs in vhci_recv_ret_submit(). That causes the error URB to still
be linked at endpoint list without “vhci_priv".
So, in the case of transaction error in vhci_recv_ret_submit(),
unlink URB from the endpoint, insert proper error code in
urb->status and give back URB.

When vhci uses SG and receives data whose size is smaller than SG
buffer size, it tries to receive more data even if it acutally
receives all the data from the server. If then, it erroneously adds
error event and triggers connection shutdown.
vhci-hcd should check if it received all the data even if there are
more SG entries left. So, check if it receivces all the data from
the server in for_each_sg() loop.

When disconnecting a USB hub that has some child device(s) connected to it
(such as a USB mouse), then the stack tries to clear halt and
reset device(s) which are _already_ physically disconnected.
The issue has been reproduced with:
CPU: IMX6D5EYM10AD or MCIMX6D5EYM10AE.
SW: U-Boot 2019.07 and kernel 4.19.40.
CPU: HP Proliant Microserver Gen8.
SW: Linux version 4.2.3-300.fc23.x86_64
In this situation there will be error bit for MMF active yet the
CERR equals EHCI_TUNE_CERR + halt. Existing implementation
interprets this as a stall [1] (chapter 8.4.5).
The possible conditions when the MMF will be active + halt
can be found from [2] (Table 4-13).
Fix for the issue is to check whether MMF is active and PID Code is
IN before checking for the stall. If these conditions are true then
it is not a stall.
What happens after the fix is that when disconnecting a hub with
attached device(s) the situation is not interpret as a stall.

There seems to be a race condition in tty drivers and I could see on
many boot cycles a NULL pointer dereference as tty_init_dev() tries to
do 'tty->port->itty = tty' even though tty->port is NULL.
'tty->port' will be set by the driver and if the driver has not yet done
it before we open the tty device we can get to this situation. By adding
some extra debug prints, I noticed that:
6.650130: uart_add_one_port
6.663849: register_console
6.664846: tty_open
6.674391: tty_init_dev
6.675456: tty_port_link_device
uart_add_one_port() registers the console, as soon as it registers, the
userspace tries to use it and that leads to tty_open() but
uart_add_one_port() has not yet done tty_port_link_device() and so
tty->port is not yet configured when control reaches tty_init_dev().
Further look into the code and tty_port_link_device() is done by
uart_add_one_port(). After registering the console uart_add_one_port()
will call tty_port_register_device_attr_serdev() and
tty_port_link_device() is called from this.
Call add tty_port_link_device() before uart_configure_port() is done and
add a check in tty_port_link_device() so that it only links the port if
it has not been done yet.

When an application sends TPM commands in NONBLOCKING mode
the driver holds chip->tpm_mutex returning from write(),
which triggers: "WARNING: lock held when returning to user space".
To fix this issue the driver needs to release the mutex before

sending the command.

The original code, before it was moved into security/keys/trusted-keys
had a flush after the blob unseal. Without that flush, the volatile
handles increase in the TPM until it becomes unusable and the system
either has to be rebooted or the TPM volatile area manually flushed.
Fix by adding back the lost flush, which we now have to export because
of the relocation of the trusted key code may cause the consumer to be
modular.
