commit fbcd13df1e78eb2ba83a3c160eefe2d6f574beaf upstream.
Stub from the spec:
"4.5.2.2.4.2 Exiting from AttachWait.SNK State
A Sink shall transition to Unattached.SNK when the state of both
the CC1 and CC2 pins is SNK.Open for at least tPDDebounce.
A DRP shall transition to Unattached.SRC when the state of both
the CC1 and CC2 pins is SNK.Open for at least tPDDebounce."
This change makes TCPM to wait in SNK_DEBOUNCED state until
CC1 and CC2 pins is SNK.Open for at least tPDDebounce. Previously,
TCPM resets the port if vbus is not present in PD_T_PS_SOURCE_ON.
This causes TCPM to loop continuously when connected to a
faulty power source that does not present vbus. Waiting in
SNK_DEBOUNCED also ensures that TCPM is adherant to
"4.5.2.2.4.2 Exiting from AttachWait.SNK State" requirements.

The free_rtllib() function frees the "dev" pointer so there is use

commit a56d3e40bda460edf3f8d6aac00ec0b322b4ab83 upstream.
USB bulk and interrupt message timeouts are specified in milliseconds
and should specifically not vary with CONFIG_HZ.
Note that the bulk-out transfer timeout was set to the endpoint
bInterval value, which should be ignored for bulk endpoints and is
typically set to zero. This meant that a failing bulk-out transfer
would never time out.
Assume that the 10 second timeout used for all other transfers is more
than enough also for the bulk-out endpoint.

commit 78cdfd62bd54af615fba9e3ca1ba35de39d3871d upstream.
The driver is using endpoint-sized buffers but must not assume that the
tx and rx buffers are of equal size or a malicious device could overflow
the slab-allocated receive buffer when doing bulk transfers.

commit a23461c47482fc232ffc9b819539d1f837adf2b1 upstream.
The driver uses endpoint-sized USB transfer buffers but up until
recently had no sanity checks on the sizes.
Commit e1f13c879a7c ("staging: comedi: check validity of wMaxPacketSize
of usb endpoints found") inadvertently fixed NULL-pointer dereferences
when accessing the transfer buffers in case a malicious device has a
zero wMaxPacketSize.
Make sure to allocate buffers large enough to handle also the other
accesses that are done without a size check (e.g. byte 18 in
vmk80xx_cnt_insn_read() for the VMK8061_MODEL) to avoid writing beyond
the buffers, for example, when doing descriptor fuzzing.
The original driver was for a low-speed device with 8-byte buffers.
Support was later added for a device that uses bulk transfers and is
presumably a full-speed device with a maximum 64-byte wMaxPacketSize.

commit 907767da8f3a925b060c740e0b5c92ea7dbec440 upstream.
The driver uses endpoint-sized USB transfer buffers but had no sanity
checks on the sizes. This can lead to zero-size-pointer dereferences or
overflowed transfer buffers in ni6501_port_command() and
ni6501_counter_command() if a (malicious) device has smaller max-packet
sizes than expected (or when doing descriptor fuzz testing).
Add the missing sanity checks to probe().

commit 536de747bc48262225889a533db6650731ab25d3 upstream.
USB transfer buffers are typically mapped for DMA and must not be
allocated on the stack or transfers will fail.
Allocate proper transfer buffers in the various command helpers and
return an error on short transfers instead of acting on random stack
data.
Note that this also fixes a stack info leak on systems where DMA is not
used as 32 bytes are always sent to the device regardless of how short
the command is.

of_genpd_add_device() is called before platform_device_register(), as it
needs to attach the genpd before the device is probed. But the spinlock
is only initialized when the device is registered.
Fix this by open-coding the spinlock initialization, cfr.
device_pm_init_common() in the internal drivers/base code, and in the
SuperH early platform code.

commit 04f5b9f539ce314f758d919a14dc7a669f3b7838 upstream.
AD7745 devices don't have the CIN2 pins and therefore can't handle related
channels. Forcing the number of AD7746 channels may lead to enabling more
channels than what the hardware actually supports.
Avoid num_channels being overwritten after first assignment.

[ Upstream commit 60c6b305c11b5fd167ce5e2ce42f3a9098c388f0 ]
TIOCSSERIAL is a horrid, underspecified, legacy interface which for most
serial devices is only useful for setting the close_delay and
closing_wait parameters.
A non-privileged user has only ever been able to set the since long
deprecated ASYNC_SPD flags and trying to change any other *supported*
feature should result in -EPERM being returned. Setting the current
values for any supported features should return success.
Fix the greybus implementation which instead indicated that the
TIOCSSERIAL ioctl was not even implemented when a non-privileged user
set the current values.

[ Upstream commit f9b9263a25dc3d2eaaa829e207434db6951ca7bc ]
The for-loop iterates with a u8 loop counter i and compares this
with the loop upper limit of riv->ieee80211->LinkDetectInfo.SlotNum
that is a u16 type. There is a potential infinite loop if SlotNum
is larger than the u8 loop counter. Fix this by making the loop
counter the same type as SlotNum.

[ Upstream commit 19c234a14eafca78e0bc14ffb8be3891096ce147 ]
While interpreting CC_STATUS, ROLE_CONTROL has to be read to make
sure that CC1/CC2 is not forced presenting Rp/Rd.
>From the TCPCI spec:
4.4.5.2 ROLE_CONTROL (Normative):
The TCPM shall write B6 (DRP) = 0b and B3..0 (CC1/CC2) if it wishes
to control the Rp/Rd directly instead of having the TCPC perform
DRP toggling autonomously. When controlling Rp/Rd directly, the
TCPM writes to B3..0 (CC1/CC2) each time it wishes to change the
CC1/CC2 values. This control is used for TCPM-TCPC implementing
Source or Sink only as well as when a connection has been detected
via DRP toggling but the TCPM wishes to attempt Try.Src or Try.Snk.
Table 4-22. CC_STATUS Register Definition:
If (ROLE_CONTROL.CC1 = Rd) or ConnectResult=1)
00b: SNK.Open (Below maximum vRa)
01b: SNK.Default (Above minimum vRd-Connect)
10b: SNK.Power1.5 (Above minimum vRd-Connect) Detects Rp-1.5A
11b: SNK.Power3.0 (Above minimum vRd-Connect) Detects Rp-3.0A
If (ROLE_CONTROL.CC2=Rd) or (ConnectResult=1)
00b: SNK.Open (Below maximum vRa)
01b: SNK.Default (Above minimum vRd-Connect)
10b: SNK.Power1.5 (Above minimum vRd-Connect) Detects Rp 1.5A

commit e78836ae76d20f38eed8c8c67f21db97529949da upstream.
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 ecdfa44610fa ("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)
with the contents copied in to a new file `rtl8192e/rtllib.h` along with
additional code in the commit 94a799425eee (tagged in Fixes).
