Kalle Valo says:
====================
wireless-drivers fixes for 5.3
Fourth set of fixes for 5.3, and hopefully really the last one. Quite
a few CVE fixes this time but at least to my knowledge none of them
have a known exploit.
mt76
* workaround firmware hang by disabling hardware encryption on MT7630E
* disable 5GHz band for MT7630E as it's not working properly
mwifiex
* fix IE parsing to avoid a heap buffer overflow
iwlwifi
* fix for QuZ device initialisation
rt2x00
* another fix for rekeying
* revert a commit causing degradation in rx signal levels
rsi
* fix a double free

When testing with a background iperf pushing 1Gbit/sec traffic and running
both ifconfig and netstat to collect statistics, some deadlocks occurred.
Ifconfig and netstat will call nv_get_stats64 to get software xmit/recv
statistics. In the commit f5d827aece36 ("forcedeth: implement
ndo_get_stats64() API"), the normal tx/rx variables is to collect tx/rx
statistics. The fix is to replace normal tx/rx variables with per
cpu 64-bit variable to collect xmit/recv statistics. The per cpu variable
will avoid deadlocks and provide fast efficient statistics updates.
In nv_probe, the per cpu variable is initialized. In nv_remove, this
per cpu variable is freed.
In xmit/recv process, this per cpu variable will be updated.
In nv_get_stats64, this per cpu variable on each cpu is added up. Then
the driver can get xmit/recv packets statistics.
A test runs for several days with this commit, the deadlocks disappear
and the performance is better.

NETDEV_TX_BUSY really should only be used by drivers that call
netif_tx_stop_queue() at the wrong moment. If dma_map_single() is
failed to map tx DMA buffer, it might trigger an infinite loop.
This patch use NETDEV_TX_OK instead of NETDEV_TX_BUSY, and change
printk to pr_err_ratelimited.

When booting with ACPI, the Geni Serial Engine is not set as the I2C/SPI
parent and thus, the wrapper (parent device) is unassigned. This causes
the kernel to crash with a null dereference error.

After the conversion to lock-less dma-api call the
increase_address_space() function can be called without any
locking. Multiple CPUs could potentially race for increasing
the address space, leading to invalid domain->mode settings
and invalid page-tables. This has been happening in the wild
under high IO load and memory pressure.
Fix the race by locking this operation. The function is
called infrequently so that this does not introduce
a performance regression in the dma-api path again.

When devices are attached to the amd_iommu in a kdump kernel, the old device
table entries (DTEs), which were copied from the crashed kernel, will be
overwritten with a new domain number. When the new DTE is written, the IOMMU
is told to flush the DTE from its internal cache--but it is not told to flush
the translation cache entries for the old domain number.
Without this patch, AMD systems using the tg3 network driver fail when kdump
tries to save the vmcore to a network system, showing network timeouts and
(sometimes) IOMMU errors in the kernel log.
This patch will flush IOMMU translation cache entries for the old domain when
a DTE gets overwritten with a new domain number.

In case of a missing (optional) gpio don't fall through up to
"ti,active-discharge-time-us" due to
devm_fwnode_get_index_gpiod_from_child() returning NULL (since
gpiod_get_from_of_node() returned NULL) but rather indicate success as

When allocating a range of LPIs for a Multi-MSI capable device,
this allocation extended to the closest power of 2.
But on the release path, the interrupts are released one by
one. This results in not releasing the "extra" range, leaking
the its_device. Trying to reprobe the device will then fail.
Fix it by releasing the LPIs the same way we allocate them.

We recently added a kfree() after the end of the loop:
if (retries == RETRIES) {
kfree(reply);
return -EINVAL;
}
There are two problems. First the test is wrong and because retries
equals RETRIES if we succeed on the last iteration through the loop.
Second if we fail on the last iteration through the loop then the kfree
is a double free.
When you're reading this code, please note the break statement at the
end of the while loop. This patch changes the loop so that if it's not
successful then "reply" is NULL and we can test for that afterward.

TISCI protocol supports for enabling the device either with exclusive
permissions for the requesting host or with sharing across the hosts.
There are certain devices which are exclusive to Linux context and
there are certain devices that are shared across different host contexts.
So add support for getting this information from DT by increasing
the power-domain cells to 2.
For keeping the DT backward compatibility intact, defaulting the
device permissions to set the exclusive flag set. In this case the
power-domain-cells is 1.

Sysfw provides an option for requesting exclusive access for a
device using the flags MSG_FLAG_DEVICE_EXCLUSIVE. If this flag is
not used, the device is meant to be shared across hosts. Once a device
is requested from a host with this flag set, any request to this
device from a different host will be nacked by sysfw. Current tisci
driver enables this flag for every device requests. But this may not
be true for all the devices. So provide a separate commands in driver
for exclusive and shared device requests.
