In HTB offload mode, qdiscs of leaf classes are grafted to netdev
queues. sch_htb expects the dev_queue field of these qdiscs to point to
the corresponding queues. However, qdisc creation may fail, and in that
case noop_qdisc is used instead. Its dev_queue doesn't point to the
right queue, so sch_htb can lose track of used netdev queues, which will
cause internal inconsistencies.
This commit fixes this bug by keeping track of the netdev queue inside
struct htb_class. All reads of cl->leaf.q->dev_queue are replaced by the
new field, the two values are synced on writes, and WARNs are added to
assert equality of the two values.
The driver API has changed: when TC_HTB_LEAF_DEL needs to move a queue,
the driver used to pass the old and new queue IDs to sch_htb. Now that
there is a new field (offload_queue) in struct htb_class that needs to
be updated on this operation, the driver will pass the old class ID to
sch_htb instead (it already knows the new class ID).

From Maor Gottlieb
====================
Fix the use of nents and orig_nents in the sg table append helpers. The
nents should be used by the DMA layer to store the number of DMA mapped
sges, the orig_nents is the number of CPU sges.
Since the sg append logic doesn't always create a SGL with exactly
orig_nents entries store a total_nents as well to allow the table to be
properly free'd and reorganize the freeing logic to share across all the
use cases.

The driver is being passed interrupts, then looking up the
same interrupts as GPIOs a second time to convert them into
interrupts and set properties on them.
This is pointless: the GPIO and irqchip APIs of a GPIO chip
are orthogonal. Just request the interrupts and be done
with it, drop reliance on any GPIO functions or definitions.
Use devres-managed functions and add a small devress quirk
to unregister the clock as well and we can rely on devres
to handle all the resources and cut down a bunch of
boilerplate in the process.

After the recent ixp4xx cleanups, the ptp driver has gained a
build failure in some configurations:
drivers/net/ethernet/xscale/ptp_ixp46x.c: In function 'ptp_ixp_init':
drivers/net/ethernet/xscale/ptp_ixp46x.c:290:51: error: 'IXP4XX_TIMESYNC_BASE_VIRT' undeclared (first use in this function)
Avoid the last bit of hardcoded constants from platform headers
by turning the ptp driver bit into a platform driver and passing
the IRQ and MMIO address as resources.
This is a bit tricky:
- The interface between the two drivers is now the new
ixp46x_ptp_find() function, replacing the global
ixp46x_phc_index variable. The call is done as late
as possible, in hwtstamp_set(), to ensure that the
ptp device is fully probed.
- As the ptp driver is now called by the network driver, the
link dependency is reversed, which in turn requires a small
Makefile hack
- The GPIO number is still left hardcoded. This is clearly not
great, but it can be addressed later. Note that commit 98ac0cc270b7
("ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER") changed the
IRQ number to something meaningless. Passing the correct IRQ
in a resource fixes this.
- When the PTP driver is disabled, ethtool .get_ts_info()
now correctly lists only software timestamping regardless
of the hardware.

Add infrastructure to maintain a pending list of HWRM commands awaiting
completion and reduce the scope of the hwrm_cmd_lock mutex so that it
protects only the request mailbox. The mailbox is free to use for one
or more concurrent commands after receiving deferred response events.
For uniformity and completeness, use the same pending list for
collecting completions for commands that respond via a completion ring.
These commands are only used for freeing rings and for IRQ test and
we only support one such command in flight.
Note deferred responses are also only supported on the main channel.
The secondary channel (KONG) does not support deferred responses.

The conversion follows this general pattern for most of the calls:
1. The input message is changed from a stack variable initialized
using bnxt_hwrm_cmd_hdr_init() to a pointer allocated and intialized
using hwrm_req_init().
2. If we don't need to read the firmware response, the hwrm_send_message()
call is replaced with hwrm_req_send().
3. If we need to read the firmware response, the mutex lock is replaced
by hwrm_req_hold() to hold the response. When the response is read, the
mutex unlock is replaced by hwrm_req_drop().
If additional DMA buffers are needed for firmware response data, the
hwrm_req_dma_slice() is used instead of calling dma_alloc_coherent().
Some minor refactoring is also done while doing these conversions.

We currently use the hwrm_cmd_lock to serialize the update of the
firmware's link status response data and the copying of link status data
to the VF. This won't work when we update the firmware message APIs, so
we use the link_lock mutex instead. All link_info data should be
updated under the link_lock mutex. Also add link_lock to functions that
touch link_info in __bnxt_open_nic() and bnxt_probe_phy(). The locking
is probably not strictly necessary during probe, but it's more consistent.

Slices are a mechanism for suballocating DMA mapped regions from the
request buffer. Such regions can be used for indirect command data
instead of creating new mappings with dma_alloc_coherent().
The advantage of using a slice is that the lifetime of the slice is
bound to the request and will be automatically unmapped when the
request is consumed.
A single external region is also supported. This allows for regions
that will not fit inside the spare request buffer space such that
the same API can be used consistently even for larger mappings.

During firmware crash recovery, it is possible for firmware to respond
to stale HWRM commands that have already timed out. Because response
buffers may be reused, any out of sequence responses need to be ignored
and only the matching seq_id should be accepted.
Also, READ_ONCE should be used for the reads from the DMA buffer to
ensure that the necessary loads are scheduled.

This change constitutes a major step towards supporting multiple
firmware commands in flight by maintaining a separate response buffer
for the duration of each request. These firmware commands are also
known as Hardware Resource Manager (HWRM) commands. Using separate
response buffers requires an API change in order for callers to be
able to free the buffer when done.
It is impossible to keep the existing APIs unchanged. The existing
usage for a simple HWRM message request such as the following:
struct input req = {0};
bnxt_hwrm_cmd_hdr_init(bp, &req, REQ_TYPE, -1, -1);
rc = hwrm_send_message(bp, &req, sizeof(req), HWRM_CMD_TIMEOUT);
if (rc)
/* error */
changes to:
struct input *req;
rc = hwrm_req_init(bp, req, REQ_TYPE);
if (rc)
/* error */
rc = hwrm_req_send(bp, req); /* consumes req */
if (rc)
/* error */
The key changes are:
1. The req is no longer allocated on the stack.
2. The caller must call hwrm_req_init() to allocate a req buffer and
check for a valid buffer.
3. The req buffer is automatically released when hwrm_req_send() returns.
4. If the caller wants to check the firmware response, the caller must
call hwrm_req_hold() to take ownership of the response buffer and
release it afterwards using hwrm_req_drop(). The caller is no longer
required to explicitly hold the hwrm_cmd_lock mutex to read the
response.
5. Because the firmware commands and responses all have different sizes,
some safeguards are added to the code.
This patch maintains legacy API compatibiltiy, implementing the old
API in terms of the new. The follow-on patches will convert all
callers to use the new APIs.

The additional response buffer serves no useful purpose. There can
be only one firmware command in flight due to the hwrm_cmd_lock mutex,
which is taken for the entire duration of any command completion,
KONG or otherwise. It is thus safe to share a single DMA buffer.
Removing the code associated with the additional mapping will simplify
matters in the next patch, which allocates response buffers from DMA
pools on a per request basis.

The caller of this function (parisc_driver_remove() in
arch/parisc/kernel/drivers.c) ignores the return value, so better don't
return any value at all to not wake wrong expectations in driver authors.
The only function that could return a non-zero value before was
ipmi_parisc_remove() which returns the return value of
ipmi_si_remove_by_dev(). Make this function return void, too, as for all
other callers the value is ignored, too.

To reset mwifiex on Surface gen4+ (Pro 4 or later gen) devices, it
seems that putting the wifi device into D3cold is required according
to errata.inf file on Windows installation (Windows/INF/errata.inf).
This patch adds a function that performs power-cycle (put into D3cold
then D0) and call the function at the end of reset_prepare().
Note: Need to also reset the parent device (bridge) of wifi on SB1;
it might be because the bridge of wifi always reports it's in D3hot.
When I tried to reset only the wifi device (not touching parent), it gave
the following error and the reset failed:
acpi device:4b: Cannot transition to power state D0 for parent in D3hot
mwifiex_pcie 0000:03:00.0: can't change power state from D3cold to D0 (config space inaccessible)

When resuming from suspend, brcmf_pcie_pm_leave_D3 will first attempt a
hot resume and then fall back to removing the PCI device and then
reprobing. If this probe fails, the kernel will oops, because brcmf_err,
which is called to report the failure will dereference the stale bus
pointer. Open code and use the default bus-less brcmf_err to avoid this.

NPC extraction profile marks layer types
NPC_LT_LB_CTAG for CTAG and NPC_LT_LB_STAG_QINQ for
STAG after parsing input packet. Those layer types
can be used to install ntuple filters using
vlan-etype option. Below are the commands and
corresponding behavior with this patch in place.
> alias nt "ethtool -U eth0 flow-type ether"
> nt vlan 5 m 0xf000 action 0
Input packets with outer VLAN id as 5 i.e,
stag packets with VLAN id 5 and ctag packets with
VLAN id as 5 are hit.
> nt vlan-etype 0x8100 action 0
All input ctag packets with any VLAN id are hit.
> nt vlan-etype 0x88A8 action 0
All input stag packets with any VLAN id are hit.
> nt vlan-etype 0x8100 vlan 5 m 0xf000 action 0
All input ctag packets with VLAN id 5 are hit.
> nt vlan-etype 0x88A8 vlan 5 m 0xf000 action 0
All input stag packets with VLAN id 5 are hit.

1GbE Intel Wired LAN Driver Updates 2021-08-27
ravindhan Gunasekaran says:
This adds support for Credit-based shaper qdisc offload from
Traffic Control system. It enables traffic prioritization and
bandwidth reservation via the Credit-Based Shaper which is
implemented in hardware by i225 controller.
Patch 1/3 adds a default cycle-time for TSN mode to be configured.
Patch 2/3 helps to separate TSN mode programming on the fly and
during reset sequence. It also simplifies handling features flags
for various TSN modes supported by i225 in the driver.
Patch 3/3 adds support for IEEE802.1Qav(CBS) standard
implemented in i225 HW. Two sets of CBS HW shapers are present
in i225 and driver enables them in the two high priority queues.

_rtl92c_phy_get_rightchnlplace()

1 warning generated.
Commit 369956ae5720 ("rtlwifi: rtl8192de: Remove redundant variable
initializations") removed the initialization of place but it appears
that this removal was in the wrong function.
_rtl92c_phy_get_rightchnlplace() returns place's value at the end of the
function so now if the if statement is false, place never gets
initialized. Add that initialization back to address the warning.
place's initialization is not necessary in
rtl92d_get_rightchnlplace_for_iqk() as place is only used within the if
statement so it can be removed, which is likely what was intended in the
first place.

The problem is that gpio_free() can sleep and the cfg_soc() can be
called with spinlocks held. One problematic call tree is:
--> ath_reset_internal() takes &sc->sc_pcu_lock spin lock
--> ath9k_hw_reset()
--> ath9k_hw_gpio_request_in()
--> ath9k_hw_gpio_request()
--> ath9k_hw_gpio_cfg_soc()
Remove gpio_free(), use error message instead, so we should make sure
there is no GPIO conflict.
Also remove ath9k_hw_gpio_free() from ath9k_hw_apply_gpio_override(),
as gpio_mask will never be set for SOC chips.

Bad header can have large length field which can cause OOB.
cptr is the last bytes for read, and the eeprom is parsed
from high to low address. The OOB, triggered by the condition
length > cptr could cause memory error with a read on
negative index.
There are some sanity check around length, but it is not
compared with cptr (the remaining bytes). Here, the
corrupted/bad EEPROM can cause panic.
I was able to reproduce the crash, but I cannot find the
log and the reproducer now. After I applied the patch, the
bug is no longer reproducible.

When receiving a beacon or probe response, we should update the
boottime_ns field which is the timestamp the frame was received at.
(cf mac80211.h)
This fixes a scanning issue with Android since it relies on this
timestamp to determine when the AP has been seen for the last time
(via the nl80211 BSS_LAST_SEEN_BOOTTIME parameter).
