commit 29b359cf6d95fd60730533f7f10464e95bd17c73 upstream.
The generation mask can be updated while netlink dump is in progress.
The pipapo set backend walk iterator cannot rely on it to infer what
view of the datastructure is to be used. Add notation to specify if user
wants to read/update the set.
Based on patch from Florian Westphal.

[ Upstream commit d23b5c577715892c87533b13923306acc6243f93 ]
At present, when we perform operations on the cgroup root_list, we must
hold the cgroup_mutex, which is a relatively heavyweight lock. In reality,
we can make operations on this list RCU-safe, eliminating the need to hold
the cgroup_mutex during traversal. Modifications to the list only occur in
the cgroup root setup and destroy paths, which should be infrequent in a
production environment. In contrast, traversal may occur frequently.
Therefore, making it RCU-safe would be beneficial.

memcmp, although this possibility mainly comes from crafted poisonous

[ Upstream commit 8fcc514809de41153b43ccbe1a0cdf7f72b78e7e ]
A Linux guest on Hyper-V gets the TSC frequency from a synthetic MSR, if
available. In this case, set X86_FEATURE_TSC_KNOWN_FREQ so that Linux
doesn't unnecessarily do refined TSC calibration when setting up the TSC
clocksource.
With this change, a message such as this is no longer output during boot
when the TSC is used as the clocksource:
[ 1.115141] tsc: Refined TSC clocksource calibration: 2918.408 MHz
Furthermore, the guest and host will have exactly the same view of the
TSC frequency, which is important for features such as the TSC deadline
timer that are emulated by the Hyper-V host.

We use komeda_crtc_normalize_zpos to normalize zpos of affected planes
to their blending zorder in CU. If there's only one slave plane in
affected planes and its layer_split property is enabled, order++ for
its split layer, so that when calculating the normalized_zpos
of master planes, the split layer of the slave plane is included, but
the max_slave_zorder does not include the split layer and keep zero
because there's only one slave plane in affacted planes, although we
actually use two slave layers in this commit.
In most cases, this bug does not result in a commit failure, but assume
the following situation:
slave_layer 0: zpos = 0, layer split enabled, normalized_zpos =
0;(use slave_layer 2 as its split layer)
master_layer 0: zpos = 2, layer_split enabled, normalized_zpos =
2;(use master_layer 2 as its split layer)
master_layer 1: zpos = 4, normalized_zpos = 4;
master_layer 3: zpos = 5, normalized_zpos = 5;
kcrtc_st->max_slave_zorder = 0;
When we use master_layer 3 as a input of CU in function
komeda_compiz_set_input and check it with function
komeda_component_check_input, the parameter idx is equal to
normailzed_zpos minus max_slave_zorder, the value of idx is 5
and is euqal to CU's max_active_inputs, so that
komeda_component_check_input returns a -EINVAL value.
To fix the bug described above, when calculating the max_slave_zorder
with the layer_split enabled, count the split layer in this calculation
directly.

There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was
recently converted from just a message), that can be hit if we
wait for TX queues to become empty after firmware died. Clearly,
we can't expect anything from the firmware after it's declared dead.
Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could
be a good idea to stop the flow earlier, the flush functions do some
maintenance work that is not related to the firmware, so keep that part
of the code running even when the firmware is not running.

Before commit 721f4a6526da ("mm/memblock: remove empty dummy entry") the
check for non-zero of memblock.reserved.cnt in mmu_init() would always
be true either because memblock.reserved.cnt is initialized to 1 or
because there were memory reservations earlier.
The removal of dummy empty entry in memblock caused this check to fail
because now memblock.reserved.cnt is initialized to 0.
Remove the check for non-zero of memblock.reserved.cnt because it's
perfectly fine to have an empty memblock.reserved array that early in
boot.

commit 233a95fd574fde1c375c486540a90304a2d2d49f upstream.
This reverts commit ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 because it
breaks codecs using non-continuous masks in source and sink ports. The
commit missed the point that port numbers are not used as indices for
iterating over prop.sink_ports or prop.source_ports.
Soundwire core and existing codecs expect that the array passed as
prop.sink_ports and prop.source_ports is continuous. The port mask still
might be non-continuous, but that's unrelated.

[ Upstream commit e843cf7b34fe2e0c1afc55e1f3057375c9b77a14 ]
When adding a switch filter (such as a MAC or VLAN filter), it is expected
that the driver will detect the case where the filter already exists, and
return -EEXIST. This is used by calling code such as ice_vc_add_mac_addr,
and ice_vsi_add_vlan to avoid incrementing the accounting fields such as
vsi->num_vlan or vf->num_mac.
This logic works correctly for the case where only a single VSI has added a
given switch filter.
When a second VSI adds the same switch filter, the driver converts the
existing filter from an ICE_FWD_TO_VSI filter into an ICE_FWD_TO_VSI_LIST
filter. This saves switch resources, by ensuring that multiple VSIs can
re-use the same filter.
The ice_add_update_vsi_list() function is responsible for doing this
conversion. When first converting a filter from the FWD_TO_VSI into
FWD_TO_VSI_LIST, it checks if the VSI being added is the same as the
existing rule's VSI. In such a case it returns -EEXIST.
However, when the switch rule has already been converted to a
FWD_TO_VSI_LIST, the logic is different. Adding a new VSI in this case just
requires extending the VSI list entry. The logic for checking if the rule
already exists in this case returns 0 instead of -EEXIST.
This breaks the accounting logic mentioned above, so the counters for how
many MAC and VLAN filters exist for a given VF or VSI no longer accurately
reflect the actual count. This breaks other code which relies on these
counts.
In typical usage this primarily affects such filters generally shared by
multiple VSIs such as VLAN 0, or broadcast and multicast MAC addresses.
Fix this by correctly reporting -EEXIST in the case of adding the same VSI
to a switch rule already converted to ICE_FWD_TO_VSI_LIST.

[ Upstream commit 20471071f198c8626dbe3951ac9834055b387844 ]
The current implementation of pmbus_show_boolean assumes that all devices
support write-back operation of status register to clear pending warnings
or faults. Since clearing individual bits in the status registers was only
introduced in PMBus specification 1.2, this operation may not be supported
by some older devices. This can result in an error while reading boolean
attributes such as temp1_max_alarm.
Fetch PMBus revision supported by the device and modify pmbus_show_boolean
so that it only tries to clear individual status bits if the device is
compliant with PMBus specs >= 1.2. Otherwise clear all fault indicators
on the current page after a fault status was reported.

Apart from the standard "configurations", "interfaces" and "alternate
interface settings" in USB, iOS devices also have a notion of
"modes". In different modes, the device exposes a different set of
available configurations.
Depending on the iOS version, and depending on the current mode, the
length and contents of the carrier state control message differs:
* 1 byte (seen on iOS 4.2.1, 8.4):
* 03: carrier off (mode 0)
* 04: carrier on (mode 0)
* 3 bytes (seen on iOS 10.3.4, 15.7.6):
* 03 03 03: carrier off (mode 0)
* 04 04 03: carrier on (mode 0)
* 4 bytes (seen on iOS 16.5, 17.6):
* 03 03 03 00: carrier off (mode 0)
* 04 03 03 00: carrier off (mode 1)
* 06 03 03 00: carrier off (mode 4)
* 04 04 03 04: carrier on (mode 0 and 1)
* 06 04 03 04: carrier on (mode 4)
Before this change, the driver always used the first byte of the
response to determine carrier state.
From this larger sample, the first byte seems to indicate the number of
available USB configurations in the current mode (with the exception of
the default mode 0), and in some cases (namely mode 1 and 4) does not
correlate with the carrier state.
Previous logic erroneously counted `04 03 03 00` as "carrier on" and
`06 04 03 04` as "carrier off" on iOS versions that support mode 1 and
mode 4 respectively.
Only modes 0, 1 and 4 expose the USB Ethernet interfaces necessary for
the ipheth driver.
Check the second byte of the control message where possible, and fall
back to checking the first byte on older iOS versions.

the link compliance test (TD7.21) may fail. If the ECN is not enabled
(GUCTL2[19] = 0), the controller will use the old timer value (5us),
which is still acceptable for the link compliance test. Therefore, clear
GUCTL2[19] to pass the USB link compliance test: TD 7.21.

commit 626dfed5fa3bfb41e0dffd796032b555b69f9cde upstream.
When using a BPF program on kernel_connect(), the call can return -EPERM. This
causes xs_tcp_setup_socket() to loop forever, filling up the syslog and causing
the kernel to potentially freeze up.
Neil suggested:
This will propagate -EPERM up into other layers which might not be ready
to handle it. It might be safer to map EPERM to an error we would be more
likely to expect from the network system - such as ECONNREFUSED or ENETDOWN.
ECONNREFUSED as error seems reasonable. For programs setting a different error
can be out of reach (see handling in 4fbac77d2d09) in particular on kernels
which do not have f10d05966196 ("bpf: Make BPF_PROG_RUN_ARRAY return -err
instead of allow boolean"), thus given that it is better to simply remap for
consistent behavior. UDP does handle EPERM in xs_udp_send_request().
