The "u16 CcxRmState[2];" array field in struct "rtllib_network" has 4
bytes in total while the operations performed on this array through-out
the code base are only 2 bytes.
The "CcxRmState" field is fed only 2 bytes of data using memcpy():
(In rtllib_rx.c:1972)
memcpy(network->CcxRmState, &info_element->data[4], 2)
With "info_element->data[]" being a u8 array, if 2 bytes are written
into "CcxRmState" (whose one element is u16 size), then the 2 u8
elements from "data[]" gets squashed and written into the first element
("CcxRmState[0]") while the second element ("CcxRmState[1]") is never
fed with any data.
Same in file rtllib_rx.c:2522:
memcpy(dst->CcxRmState, src->CcxRmState, 2);
The above line duplicates "src" data to "dst" but only writes 2 bytes
(and not 4, which is the actual size). Again, only 1st element gets the
value while the 2nd element remains uninitialized.
This later makes operations done with CcxRmState unpredictable in the
following lines as the 1st element is having a squashed number while the
2nd element is having an uninitialized random number.
rtllib_rx.c:1973: if (network->CcxRmState[0] != 0)
rtllib_rx.c:1977: network->MBssidMask = network->CcxRmState[1] & 0x07;
network->MBssidMask is also of type u8 and not u16.
Fix this by changing the type of "CcxRmState" from u16 to u8 so that the
data written into this array and read from it make sense and are not
random values.
NOTE: The wrong initialization of "CcxRmState" can be seen in the
following commit:
commit ecdfa44610 ("Staging: add Realtek 8192 PCI wireless driver")
The above commit created a file `rtl8192e/ieee80211.h` which used to
have the faulty line. The file has been deleted (or possibly renamed)

The variable "info_element" is of the following type:
struct rtllib_info_element *info_element
defined in drivers/staging/rtl8192e/rtllib.h:
struct rtllib_info_element {
u8 id;
u8 len;
u8 data[];
} __packed;
The "len" field defines the size of the "data[]" array. The code is
supposed to check if "info_element->len" is greater than 4 and later
equal to 6. If this is satisfied then, the last two bytes (the 4th and
5th element of u8 "data[]" array) are copied into "network->CcxRmState".
Right now the code uses "memcpy()" with the source as "&info_element[4]"
which would copy in wrong and unintended information. The struct
"rtllib_info_element" has a size of 2 bytes for "id" and "len",
therefore indexing will be done in interval of 2 bytes. So,
"info_element[4]" would point to data which is beyond the memory
allocated for this pointer (that is, at x+8, while "info_element" has
been allocated only from x to x+7 (2 + 6 => 8 bytes)).
This patch rectifies this error by using "&info_element->data[4]" which
correctly copies the last two bytes of "data[]".
NOTE: The faulty line of code came from the following commit:
commit ecdfa44610 ("Staging: add Realtek 8192 PCI wireless driver")
The above commit created the file `rtl8192e/ieee80211/ieee80211_rx.c`

Function r8712_sitesurvey_cmd calls memcpy without checking the length.
A user could control that length and trigger a buffer overflow.
Fix by checking the length is within the maximum allowed size.

The memdup_user() function does not necessarily return a NUL terminated
string so this can lead to a read overflow. Switch from memdup_user()
to strndup_user() to fix this bug.

Here is the large set of char/misc/whatever driver subsystem updates for
5.12-rc1. Over time it seems like this tree is collecting more and more
tiny driver subsystems in one place, making it easier for those
maintainers, which is why this is getting larger.
Included in here are:
- coresight driver updates
- habannalabs driver updates
- virtual acrn driver addition (proper acks from the x86
maintainers)
- broadcom misc driver addition
- speakup driver updates
- soundwire driver updates
- fpga driver updates
- amba driver updates
- mei driver updates
- vfio driver updates
- greybus driver updates
- nvmeem driver updates
- phy driver updates
- mhi driver updates
- interconnect driver udpates
- fsl-mc bus driver updates
- random driver fix
- some small misc driver updates (rtsx, pvpanic, etc.)
All of these have been in linux-next for a while, with the only reported
issue being a merge conflict in include/linux/mod_devicetable.h that you
will hit in your tree due to the dfl_device_id addition from the fpga
subsystem in here. The resolution should be simple.

Here is the "big" set of staging and IIO driver patches for 5.12-rc1.
Nothing really huge in here, the number of staging tree patches has gone
down for a bit, maybe there's only so much churn to happen in here at
the moment.
The IIO changes are:
- new drivers
- new DT bindings
- new iio driver features
with full details in the shortlog.
The staging driver patches are just a lot of tiny coding style cleanups,
along with some semi-larger hikey driver cleanups as those are _almost_
good enough to get out of the staging tree, but will probably have to
wait until 5.13 to have happen.
All of these have been in linux-next with no reported issues.

This switchdev attribute offers a counterproductive API for a driver
writer, because although br_switchdev_set_port_flag gets passed a
"flags" and a "mask", those are passed piecemeal to the driver, so while
the PRE_BRIDGE_FLAGS listener knows what changed because it has the
"mask", the BRIDGE_FLAGS listener doesn't, because it only has the final
value. But certain drivers can offload only certain combinations of
settings, like for example they cannot change unicast flooding
independently of multicast flooding - they must be both on or both off.
The way the information is passed to switchdev makes drivers not
expressive enough, and unable to reject this request ahead of time, in
the PRE_BRIDGE_FLAGS notifier, so they are forced to reject it during
the deferred BRIDGE_FLAGS attribute, where the rejection is currently
ignored.
This patch also changes drivers to make use of the "mask" field for edge
detection when possible.
