Wei Li bd3c628f8f perf tools: Fix record failure when mixed with ARM SPE event
When recording with cache-misses and arm_spe_x event, I found that it
will just fail without showing any error info if i put cache-misses
after 'arm_spe_x' event.

  [root@localhost 0620]# perf record -e cache-misses \
				-e arm_spe_0/ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/ sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.067 MB perf.data ]

  [root@localhost 0620]# perf record -e arm_spe_0/ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/ \
				     -e  cache-misses sleep 1
  [root@localhost 0620]#

The current code can only work if the only event to be traced is an
'arm_spe_x', or if it is the last event to be specified. Otherwise the
last event type will be checked against all the arm_spe_pmus[i]->types,
none will match and an out of bound 'i' index will be used in
arm_spe_recording_init().

We don't support concurrent multiple arm_spe_x events currently, that
is checked in arm_spe_recording_options(), and it will show the relevant
info. So add the check and record of the first found 'arm_spe_pmu' to
fix this issue here.

Thomas Richter 463538a383 perf tests: Fix test 68 zstd compression for s390
Commit 5aa98879ef ("s390/cpum_sf: prohibit callchain data collection")
prohibits call graph sampling for hardware events on s390. The

Therefore omit call graph sampling on s390 in this test.

The token variable in the process_dynamic_array_len function is
allocated in the read_expect_type function, but is not freed before
calling the read_token function.

Free the token variable before calling read_token in order to plug the
leak.

Johannes Berg c8ad010665 mac80211: warn only once in check_sdata_in_driver() at each caller
Ben Greear has repeatedly reported in the past (for a few years
probably) that this triggers repeatedly in certain scenarios.

Make this a macro so that each callsite can trigger the warning
only once - that will still give us an idea of what's going on
and what paths can reach it, but avoids being too noisy.

Chung-Hsien Hsu f96622749a nl80211: support 4-way handshake offloading for WPA/WPA2-PSK in AP mode
Let drivers advertise support for AP-mode WPA/WPA2-PSK 4-way handshake
offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_AP_PSK flag.

Extend use of NL80211_ATTR_PMK attribute indicating it might be passed
as part of NL80211_CMD_START_AP command, and contain the PSK (which is
the PMK, hence the name).

The driver is assumed to handle the 4-way handshake by itself in this
case, instead of relying on userspace.

Johannes Berg 75e6b594bb cfg80211: invert HE BSS color 'disabled' to 'enabled'
This is in fact 'disabled' in the spec, but there it's in a
place where that actually makes sense. In our internal data
structures, it doesn't really make sense, and in fact the
previous commit just fixed a bug in that area.

Make this safer by inverting the polarity from 'disabled' to
'enabled'.

Mathy Vanhoef cb17ed29a7 mac80211: parse radiotap header when selecting Tx queue
Already parse the radiotap header in ieee80211_monitor_select_queue.
In a subsequent commit this will allow us to add a radiotap flag that
influences the queue on which injected packets will be sent.

This also fixes the incomplete validation of the injected frame in
ieee80211_monitor_select_queue: currently an out of bounds memory
access may occur in in the called function ieee80211_select_queue_80211
if the 802.11 header is too small.

Note that in ieee80211_monitor_start_xmit the radiotap header is parsed
again, which is necessairy because ieee80211_monitor_select_queue is not
always called beforehand.

AQL does not take into account that most HT/VHT/HE traffic is A-MPDU aggregated.
Because of that, the per-packet airtime overhead is vastly overestimated.
Improve it by assuming an average aggregation length of 16 for non-legacy

Linus Lüssing e3718a6114 cfg80211/mac80211: add mesh_param "mesh_nolearn" to skip path discovery
Currently, before being able to forward a packet between two 802.11s
nodes, both a PLINK handshake is performed upon receiving a beacon and
then later a PREQ/PREP exchange for path discovery is performed on
demand upon receiving a data frame to forward.

When running a mesh protocol on top of an 802.11s interface, like
batman-adv, we do not need the multi-hop mesh routing capabilities of
802.11s and usually set mesh_fwding=0. However, even with mesh_fwding=0
the PREQ/PREP path discovery is still performed on demand. Even though
in this scenario the next hop PREQ/PREP will determine is always the
direct 11s neighbor node.

The new mesh_nolearn parameter allows to skip the PREQ/PREP exchange in
this scenario, leading to a reduced delay, reduced packet buffering and
simplifies HWMP in general.

mesh_nolearn is still rather conservative in that if the packet destination
is not a direct 11s neighbor, it will fall back to PREQ/PREP path
discovery.

For normal, multi-hop 802.11s mesh routing it is usually not advisable
to enable mesh_nolearn as a transmission to a direct but distant neighbor
might be worse than reaching that same node via a more robust /
higher throughput etc. multi-hop path.

Emmanuel Grumbach 2f1805ea20 cfg80211: allow the low level driver to flush the BSS table
The low level driver adds its own opaque information
in the BSS table in the cfg80211_bss structure.

The low level driver may need to signal that this information
is no longer relevant and needs to be recreated.
Add an API to allow the low level driver to do that.

iwlwifi needs this because it keeps there an information about
the firmware's internal clock. This is kept in mac80211's
struct ieee80211_bss::sync_device_ts.
This information is populated while we scan, we add the
internal firmware's clock to each beacon which allows us to
program the firmware correctly after association so that
it'll know when (in terms of its internal clock) the DTIM
and TBTT will happen.

When the firmware is reset this internal clock is reset as
well and ieee80211_bss::sync_device_ts is no longer accurate.

iwlwifi will call this new API any time the firmware is started.

Julian Squires 9c167b2ddc cfg80211: allow vendor dumpit to terminate by returning 0
nl80211 vendor netlink dumpit, like netlink_callback->dump, should
signal successful completion by returning 0.

Currently, that will just cause dumpit to be called again, possibly
many times until an error occurs.  Since skb->len is never going to be
0 by the time dumpit is called, the only way for dumpit to signal
completion is by returning an error.  If it returns a positive value,
the current message is cancelled, but that positive value is returned
and nl80211_vendor_cmd_dump gets called again.

Fix that by passing a return value of 0 through.

Alain Michaud 9a9373ffc7 Bluetooth: use the proper scan params when conn is pending
When an LE connection is requested and an RPA update is needed via
hci_connect_le_scan, the default scanning parameters are used rather
than the connect parameters.  This leads to significant delays in the
connection establishment process when using lower duty cycle scanning
parameters.

The patch simply looks at the pended connection list when trying to
determine which scanning parameters should be used.

James Jones faa0fcf943 drm/nouveau: Accept 'legacy' format modifiers
Accept the DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK()
family of modifiers to handle broken userspace
Xorg modesetting and Mesa drivers. Existing Mesa
drivers are still aware of only these older
format modifiers which do not differentiate
between different variations of the block linear
layout. When the format modifier support flag was
flipped in the nouveau kernel driver, the X.org
modesetting driver began attempting to use its
format modifier-enabled framebuffer path. Because
the set of format modifiers advertised by the
kernel prior to this change do not intersect with
the set of format modifiers advertised by Mesa,
allocating GBM buffers using format modifiers
fails and the modesetting driver falls back to
non-modifier allocation. However, it still later
queries the modifier of the GBM buffer when
creating its DRM-KMS framebuffer object, receives
the old-format modifier from Mesa, and attempts
to create a framebuffer with it. Since the kernel
is still not aware of these formats, this fails.

Userspace should not be attempting to query format
modifiers of GBM buffers allocated with a non-
format-modifier-aware allocation path, but to
avoid breaking existing userspace behavior, this
change accepts the old-style format modifiers when
creating framebuffers and applying them to planes
by translating them to the equivalent new-style
modifier. To accomplish this, some layout
parameters must be assumed to match properties of
the device targeted by the relevant ioctls. To
avoid perpetuating misuse of the old-style
modifiers, this change does not advertise support
for them. Doing so would imply compatibility
between devices with incompatible memory layouts.

Tested with Xorg 1.20 modesetting driver,

Xin Xiong e692139e6a net/mlx5e: fix bpf_prog reference count leaks in mlx5e_alloc_rq
The function invokes bpf_prog_inc(), which increases the reference
count of a bpf_prog object "rq->xdp_prog" if the object isn't NULL.

The refcount leak issues take place in two error handling paths. When
either mlx5_wq_ll_create() or mlx5_wq_cyc_create() fails, the function
simply returns the error code and forgets to drop the reference count
increased earlier, causing a reference count leak of "rq->xdp_prog".

Fix this issue by jumping to the error handling path err_rq_wq_destroy
while either function fails.

Jianbo Liu 0faddfe6b7 net/mlx5e: E-Switch, Add misc bit when misc fields changed for mirroring
The modified flow_context fields in FTE must be indicated in
modify_enable bitmask. Previously, the misc bit in modify_enable is
always set as source vport must be set for each rule. So, when parsing
vxlan/gre/geneve/qinq rules, this bit is not set because those are all
from the same misc fileds that source vport fields are located at, and
we don't need to set the indicator twice.

After adding per vport tables for mirroring, misc bit is not set, then
firmware syndrome happens. To fix it, set the bit wherever misc fileds
are changed. This also makes it unnecessary to check misc fields and set
the misc bit accordingly in metadata matching, so here remove it.

Besides, flow_source must be specified for uplink because firmware
will check it and some actions are only allowed for packets received
from uplink.

Wang Hai bd69058f50 net: ll_temac: Use devm_platform_ioremap_resource_byname()
platform_get_resource() may fail and return NULL, so we had better
check its return value to avoid a NULL pointer dereference a bit later
in the code. Fix it to use devm_platform_ioremap_resource_byname()
instead of calling platform_get_resource_byname() and devm_ioremap().

====================
net: ethernet: use generic power management

Linux Kernel Mentee: Remove Legacy Power Management.

The purpose of this patch series is to upgrade power management in net ethernet
drivers. This has been done by upgrading .suspend() and .resume() callbacks.

The upgrade makes sure that the involvement of PCI Core does not change the
order of operations executed in a driver. Thus, does not change its behavior.

In general, drivers with legacy PM, .suspend() and .resume() make use of PCI
helper functions like pci_enable/disable_device_mem(), pci_set_power_state(),
pci_save/restore_state(), pci_enable/disable_device(), etc. to complete
their job.

The conversion requires the removal of those function calls, change the
callbacks' definition accordingly and make use of dev_pm_ops structure.

All patches are compile-tested only.

Test tools:
    - Compiler: gcc (GCC) 10.1.0
    - allmodconfig build: make -j$(nproc) W=1 all

Vaibhav Gupta 04db64652e tlan: use generic power management
Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.

Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.
