When we abort the scan because of a firmware crash, we
need to cancel the delayed work that monitors the scan
completion. Otherwise it'll kick and try to restart the
firmware yet another time.

Add an entry for SnJ with Hr1. This device should use the
tx_with_siso_diversity option, but that doesn't work at the moment.
So we leave it disabled for now (and use the same struct as Hr2).

We were starting the early time-point too late in non-unified
firmwares. Unlike with unified firmwares, we were starting it only
after reading the NVM, so errors in the NVM read phase were not
logged.
Solve this by moving the time-point to the same place as we do with
unified firmwares, i.e. just before we go into the wait-alive code.

We were hardcoding the SnJ and So IDs already at the trans_cfg
selection, instead of doing it in a more generic way. Use the generic
trans_cfg selection for these devices and move the hardcoded IDs to

The "supp" variable doesn't need to be unsigned long, only

In struct iwl_tx_cmd, there's no risk (as Arnd implied) that we
might access this as an array, as it's really not an array and
cannot be - there's only a single 802.11 header per frame. The
only reason for this member is for being able to access it a
bit more nicely.
On the other hand, this structure is used as a sub-struct in a
few places, and then some compilers (e.g. clang with certain
options) complain as you shouldn't have structs with variable-
length fields embedded in other structs.

If the firmware has support, then advertise it to the stack and
send the key down. Since we re-check the protection in the host
anyway, we don't really need to do anything on RX except that we
should drop frames that the firmware _knows_ are replay errors,
since beacon filtering might otherwise result in replays being
possible.

When we check the length, we only check that the advertised
data length fits into the data we have, but currently not
that it actually matches correctly.
This should be harmless, but if the first two bytes are zero,
then the iwl_rx_packet_payload_len() ends up negative, and
that might later cause issues if unsigned variables are used,
as this is not something that's normally expected.
Change the validation here to precisely validate the lengths
match, to avoid such issues.

In roaming flows and during reassociation, its possible that data frames
such as EAPOLs for 4 way handshake/ 802.1x authentication are initially set
to higher MCS rate. Though these are pruned down to a lower legacy rate
before sending to the FW, driver also emits a kernel warning - intended for
non-data frames. Add checks to avoid such warnings for data frames, while
also enhancing the debug data printed.

D3_CONFIG_CMD and D0I3_END_CMD should be the last\first
command upon suspend\resume correspondingly, otherwise,
FW will raise an assert (0x342).
There are firmware notifications that cause the driver to
send a command back to the firmware. If such a notification
is sent to the driver while the the driver prepares the
firmware for D3, operation, what is likely to happen is that
the handling of the notification will try to get the mutex
and will wait unil the driver finished configuring the
firmware for D3. Then the handling notification will get
the mutex and handle the notification which will lead to
the aforementioned ASSERT 342.
To avoid this, we need to prevent any command to be sent to
the firmware between the D3_CONFIG_CMD and the D0I3_END_CMD.
Check this in the utility layer that sends the host commands
and in the transport layer as well.
Flag the D3_CONFIG_CMD and the D0I3_END_CMD commands as
commands that must be sent even if the firmware has already
been configured for D3 operation.

When we want to stop TX'ing because we are suspending, we
have two options: either we check system_pm_mode or we
check the mvm's status that has a bit for the suspend
flow.
The latter is better because test_bit is atomic. Also
add a call to synchronize_net after we set the bit to
make sure that all the new Tx see the bit before we
actually complete the suspend flow.

If there are frequent CCA delays due to the extension channel
as detected by the firmware, and we're on 2.4 GHz, then handle
this by disconnecting (with a reconnect hint).
When we disconnect, we'll also update our capabilities to use
only 20 MHz on the next connection (if it's on 2.4 GHz) as to
avoid the use of the extension channel that has too much noise.

When restarting firmware with an ongoing scheduled scan, we
don't (and shouldn't) mark it as aborted as mac80211 will be
restarting it, and so no event should go out to userspace.
The appropriate comment regarding this wasn't moved to this
place, so add it.
However, we _do_ need to clean up our internal state, since
mac80211 will restart the scan, and we'll otherwise get to
the WARN_ON() a few lines below for no reason whatsoever.

We shouldn't trust the firmware with the sizes (or contents)
of notifications, accessing too much data could cause page
faults if the data doesn't fit into the allocated space. This
applies more on older NICs where multiple notifications can
be in a single RX buffer.
Add a general framework for checking a minimum size of any
notification in the RX handlers and use it for most. Some RX
handlers were already checking and I've moved the checks,
some more complex checks I left and made them _NO_SIZE for
the RX handlers.

PTE insertion is fundamentally racy, and this check doesn't do anything
useful. Quoting Sean:
"Yeah, it can be whacked. The original, never-upstreamed code asserted
that the resolved PFN matched the PFN being installed by the fault
handler as a sanity check on the SGX driver's EPC management. The
WARN assertion got dropped for whatever reason, leaving that useless
chunk."
Jason stumbled over this as a new user of follow_pfn(), and I'm trying
to get rid of unsafe callers of that function so it can be locked down
further.

dwc2_hsotg_process_req_status uses ep_from_windex() to retrieve
the endpoint for the index provided in the wIndex request param.
In a test-case with a rndis gadget running and sending a malformed
packet to it like:
dev.ctrl_transfer(
0x82, # bmRequestType
0x00, # bRequest
0x0000, # wValue
0x0001, # wIndex
0x00 # wLength
)
it is possible to cause a crash:
[ 217.533022] dwc2 ff300000.usb: dwc2_hsotg_process_req_status: USB_REQ_GET_STATUS
[ 217.559003] Unable to handle kernel read from unreadable memory at virtual address 0000000000000088

[ 218.368056] dwc2_hsotg_complete_request+0x144/0x184
This happens because ep_from_windex wants to compare the endpoint
direction even if index_to_ep() didn't return an endpoint due to
the direction not matching.
The fix is easy insofar that the actual direction check is already
happening when calling index_to_ep() which will return NULL if there
is no endpoint for the targeted direction, so the offending check
can go away completely.

Commit fe8abf332b8f ("usb: dwc3: support clocks and resets for DWC3
core") introduced clock support and a new function named
dwc3_core_init_for_resume() which enables the clock before calling
dwc3_core_init() during resume as clocks get disabled during suspend.
Unfortunately in this commit the DWC3_GCTL_PRTCAP_OTG case was forgotten
and therefore during resume, a platform could call dwc3_core_init()
without re-enabling the clocks first, preventing to resume properly.
So update the resume path to call dwc3_core_init_for_resume() as it
should.

ARM randconfig builds with lld sometimes show a build failure
from kallsyms:
Inconsistent kallsyms data
Try make KALLSYMS_EXTRA_PASS=1 as a workaround
The problem is the veneers/thunks getting added by the linker extend
the symbol table, which in turn leads to more veneers being needed,
so it may take a few extra iterations to converge.
This bug has been fixed multiple times before, but comes back every time
a new symbol name is used. lld uses a different set of identifiers from
ld.bfd, so the additional ones need to be added as well.
I looked through the sources and found that arm64 and mips define similar
prefixes, so I'm adding those as well, aside from the ones I observed. I'm
not sure about powerpc64, which seems to already be handled through a
section match, but if it comes back, the "__long_branch_" and "__plt_"
prefixes would have to get added as well.

Sedat Dilek noticed duplicated flags in DEBUG_CFLAGS when building
deb-pkg with CONFIG_DEBUG_INFO. For example, 'make CC=clang bindeb-pkg'
reproduces the issue.
Kbuild recurses to the top Makefile for some targets such as package
builds.
With commit 121c5d08d53c ("kbuild: Only add -fno-var-tracking-assignments
for old GCC versions") applied, DEBUG_CFLAGS is now reset only when
CONFIG_CC_IS_GCC=y.
Fix it to reset DEBUG_CFLAGS all the time.

This version will contain all the (major or even only minor) changes for
Linux 5.12.
The version number isn't a semantic version number with major and minor
information. It is just encoding the year of the expected publishing as
Linux -rc1 and the number of published versions this year (starting at 0).

The recv_buf buffers are allocated in netvsc_device_add(). Later in
netvsc_init_buf() the response to NVSP_MSG1_TYPE_SEND_RECV_BUF allows
the host to set up a recv_section_size that could be bigger than the
(default) value used for that allocation. The host-controlled value
could be used by a malicious host to bypass the check on the packet's
length in netvsc_receive() and hence to overflow the recv_buf buffer.
Move the allocation of the recv_buf buffers into netvsc_init_but().

For runtime resuming, the RTL8153B may be resumed from the state
of power cut, when enabling the feature of UPS. Then, the PHY
would be reset, so it is necessary to be initailized again.
Besides, the USB_U1U2_TIMER also has to be set again, so I move
it from r8153b_init() to r8153b_hw_phy_cfg().

Replace r8153_patch_request() with rtl_phy_patch_request().
Replace r8153_pre_ram_code() with rtl_pre_ram_code().
Replace r8153_post_ram_code() with rtl_post_ram_code().
Add rtl_patch_key_set().
The new functions have an additional parameter. It is used to wait
the patch request command finished. When the PHY is resumed from
the state of power cut, the PHY is at a safe mode and the
OCP_PHY_PATCH_STAT wouldn't be updated. For this situation, it is
safe to set patch request command without waiting OCP_PHY_PATCH_STAT.

Michael tried to enable Advanced Error Reporting through the ENETC's
Root Complex Event Collector, and the system started spitting out single
bit correctable ECC errors coming from the ENETC interfaces:
pcieport 0000:00:1f.0: AER: Multiple Corrected error received: 0000:00:00.0
fsl_enetc 0000:00:00.0: PCIe Bus Error: severity=Corrected, type=Transaction Layer, (Receiver ID)
fsl_enetc 0000:00:00.0: device [1957:e100] error status/mask=00004000/00000000
fsl_enetc 0000:00:00.0: [14] CorrIntErr
fsl_enetc 0000:00:00.1: PCIe Bus Error: severity=Corrected, type=Transaction Layer, (Receiver ID)
fsl_enetc 0000:00:00.1: device [1957:e100] error status/mask=00004000/00000000
fsl_enetc 0000:00:00.1: [14] CorrIntErr
Further investigating the port correctable memory error detect register
(PCMEDR) shows that these AER errors have an associated SOURCE_ID of 6
(RFS/RSS):
$ devmem 0x1f8010e10 32
0xC0000006
$ devmem 0x1f8050e10 32
0xC0000006
Discussion with the hardware design engineers reveals that on LS1028A,
the hardware does not do initialization of that RFS/RSS memory, and that
software should clear/initialize the entire table before starting to
operate. That comes as a bit of a surprise, since the driver does not do
initialization of the RFS memory. Also, the initialization of the
Receive Side Scaling is done only partially.
Even though the entire ENETC IP has a single shared flow steering
memory, the flow steering service should returns matches only for TCAM
entries that are within the range of the Station Interface that is doing
the search. Therefore, it should be sufficient for a Station Interface
to initialize all of its own entries in order to avoid any ECC errors,
and only the Station Interfaces in use should need initialization.
There are Physical Station Interfaces associated with PCIe PFs and
Virtual Station Interfaces associated with PCIe VFs. We let the PF
driver initialize the entire port's memory, which includes the RFS
entries which are going to be used by the VF.

On read, master should send 31 MSB of the register (only even values
are ever used), followed by a 1 to indicate read. Then, reading two
bytes, the device will output the register's value.
On write, master sends 31 MSB of the register, followed by a 0 to
indicate write, followed by two bytes containing the register value.
Flexibilis' documentation (version 1.3) specifies the opposite
polarity (#read/write), but the scope indicates that it is, in fact,
read/#write.
