The thermal zone device structure is exposed to the different drivers
and obviously they access the internals while that should be
restricted to the core thermal code.
In order to self-encapsulate the thermal core code, we need to prevent
the drivers accessing directly the thermal zone structure and provide
accessor functions to deal with.
Use the devdata accessor introduced in the previous patch.
No functional changes intended.

Almost all gpio drivers include linux/gpio/driver.h, and other
files should not rely on includes from this header.
Remove the indirect include from here and include the correct
headers directly from where they are used.

There are only a handful of users of gpio_export() and
related functions.
As these are just wrappers around the modern gpiod_export()
helper, remove the wrappers and open-code the gpio_to_desc
in all callers to shrink the legacy API.

Qualcomm driver updates for v6.4
The Qualcomm SCM driver will now always clear the download bit, avoiding
entering download mode on a clean reboot because the bootloader left it
set. The vmid bitmap passed to qcom_scm_assign_mem() is transitioned to
a well defined size. SM6375 support is added, and SC8180X,
QDU1000/QRU1000, IPQ5332 and IPQ9574 compatibles are documented.
GENI gains support for newer hardware with deeper FIFOs.
The BWMON driver is updated to better handle the two register blocks,
which are not consistent between MSM8998 and newer platforms.
The LLCC driver no longer assumes a fixes stride across the various
banks, and instead acquire the bank placement from DeviceTree. EDAC
support for polling is introduced. EDAC support on SDM845 is disabled,
as its been observed that accessing relevant registers is not permitted
on most devices.
PMIC GLINK is reworked to support defining which auxiliary children to
spawn per platform, support for spawning a UCSI child is added and
SM8450 and SM8550 is introduced.
The RPM power-domain driver is cleaned up by moving and generalizing
structures that are common between platforms, rather than duplicating
everything. Macros are replaced with just direct definition of the
relevant structures. Support for defining parent relationships between
the power-domains is introduced, like it has been in rpmhpd for a long
time.
Number of processors has gone up, so max processor count in SMEM
is bumped again. Error handling in SMSM is cleaned up using
dev_err_probe().
Socinfo is taught about IPQ9574, QCM2290, QRB2210, QRB4210, SM7150,
SA8775P and a number of PMICs.

bitmap instead of architecture-dependent "unsigned int" which varies in

- Updates and additions to MAINTAINERS files, with Boqun being added to
the RCU entry and Zqiang being added as an RCU reviewer.
I have also transitioned from reviewer to maintainer; however, Paul
will be taking over sending RCU pull-requests for the next merge
window.
- Resolution of hotplug warning in nohz code, achieved by fixing
cpu_is_hotpluggable() through interaction with the nohz subsystem.
Tick dependency modifications by Zqiang, focusing on fixing usage of
the TICK_DEP_BIT_RCU_EXP bitmask.
- Avoid needless calls to the rcu-lazy shrinker for CONFIG_RCU_LAZY=n
kernels, fixed by Zqiang.
- Improvements to rcu-tasks stall reporting by Neeraj.
- Initial renaming of k[v]free_rcu() to k[v]free_rcu_mightsleep() for
increased robustness, affecting several components like mac802154,
drbd, vmw_vmci, tracing, and more.
A report by Eric Dumazet showed that the API could be unknowingly
used in an atomic context, so we'd rather make sure they know what
they're asking for by being explicit:
https://lore.kernel.org/all/20221202052847.2623997-1-edumazet@google.com/
- Documentation updates, including corrections to spelling,
clarifications in comments, and improvements to the srcu_size_state
comments.
- Better srcu_struct cache locality for readers, by adjusting the size
of srcu_struct in support of SRCU usage by Christoph Hellwig.
- Teach lockdep to detect deadlocks between srcu_read_lock() vs
synchronize_srcu() contributed by Boqun.
Previously lockdep could not detect such deadlocks, now it can.
- Integration of rcutorture and rcu-related tools, targeted for v6.4
from Boqun's tree, featuring new SRCU deadlock scenarios, test_nmis
module parameter, and more
- Miscellaneous changes, various code cleanups and comment improvements

The kfree_rcu() and kvfree_rcu() macros' single-argument forms are
deprecated. Therefore switch to the new kfree_rcu_mightsleep() and
kvfree_rcu_mightsleep() variants. The goal is to avoid accidental use
of the single-argument forms, which can introduce functionality bugs in
atomic contexts and latency bugs in non-atomic contexts.

This returns a pointer to the current iovec entry in the iterator. Only
useful with ITER_IOVEC right now, but it prepares us to treat ITER_UBUF
and ITER_IOVEC identically for the first segment.
Rename struct iov_iter->iov to iov_iter->__iov to find any potentially
troublesome spots, and also to prevent anyone from adding new code that
accesses iter->iov directly.

ath9k_mci_update_wlan_channels()
This partially reverts commit e161d4b60ae3a5356e07202e0bfedb5fad82c6aa.
Turns out the channelmap variable is not actually read-only, it's modified
through the MCI_GPM_CLR_CHANNEL_BIT() macro further down in the function,
so making it read-only causes page faults when that code is hit.

During initialization the driver issues a reset command via its command
interface in order to remove previous configuration from the device.
After issuing the reset, the driver waits for 200ms before polling on
the "system_status" register using memory-mapped IO until the device
reaches a ready state (0x5E). The wait is necessary because the reset
command only triggers the reset, but the reset itself happens
asynchronously. If the driver starts polling too soon, the read of the
"system_status" register will never return and the system will crash
[1].
The issue was discovered when the device was flashed with a development
firmware version where the reset routine took longer to complete. The
issue was fixed in the firmware, but it exposed the fact that the
current wait time is borderline.
Fix by increasing the wait time from 200ms to 400ms. With this patch and
the buggy firmware version, the issue did not reproduce in 10 reboots
whereas without the patch the issue is reproduced quite consistently.

When a net device is put administratively up, its 'IFF_UP' flag is set
(if not set already) and a 'NETDEV_UP' notification is emitted, which
causes the 8021q driver to add VLAN ID 0 on the device. The reverse
happens when a net device is put administratively down.
When changing the type of a bond to Ethernet, its 'IFF_UP' flag is
incorrectly cleared, resulting in the kernel skipping the above process
and VLAN ID 0 being leaked [1].
Fix by restoring the flag when changing the type to Ethernet, in a
similar fashion to the restoration of the 'IFF_SLAVE' flag.
The issue can be reproduced using the script in [2], with example out
before and after the fix in [3].

Function mlxfw_mfa2_tlv_multi_get() returns NULL if 'tlv' in
question does not pass checks in mlxfw_mfa2_tlv_payload_get(). This
behaviour may lead to NULL pointer dereference in 'multi->total_len'.
Fix this issue by testing mlxfw_mfa2_tlv_multi_get()'s return value
against NULL.

In the driver unload path, the driver currently checks the valid
BNXT_FLAG_ROCE_CAP flag in bnxt_rdma_aux_device_uninit() before
proceeding. This is flawed because the flag may not be set initially
during driver load. It may be set later after the NVRAM setting is
changed followed by a firmware reset. Relying on the
BNXT_FLAG_ROCE_CAP flag may crash in bnxt_rdma_aux_device_uninit() if
the aux device was never initialized:

Fix this by modifying the check inside bnxt_rdma_aux_device_uninit()
to check for bp->aux_priv instead. We also need to make some changes
in bnxt_rdma_aux_device_init() to make sure that bp->aux_priv is set
only when the aux device is fully initialized.

The driver does not support PTP on these older chips and it is assuming
that firmware on these older chips will not return the
PORT_MAC_PTP_QCFG_RESP_FLAGS_HWRM_ACCESS flag in __bnxt_hwrm_ptp_qcfg(),
causing the function to abort quietly.
But newer firmware now sets this flag and so __bnxt_hwrm_ptp_qcfg()
will proceed further. Eventually it will fail in bnxt_ptp_init() ->
bnxt_map_ptp_regs() because there is no code to support the older chips.
The driver will then complain:
"PTP initialization failed.\n"
Fix it so that we abort quietly earlier without going through the
unnecessary steps and alarming the user with the warning log.

The flower_stats_timer can schedule flower_stats_work and
flower_stats_work can also arm the flower_stats_timer. The
process is shown below:
----------- timer schedules work ------------
ch_flower_stats_cb() //timer handler
schedule_work(&adap->flower_stats_work);
----------- work arms timer ------------
ch_flower_stats_handler() //workqueue callback function
mod_timer(&adap->flower_stats_timer, ...);
When the cxgb4 device is detaching, the timer and workqueue
could still be rearmed. The process is shown below:
(cleanup routine) | (timer and workqueue routine)
remove_one() |
free_some_resources() | ch_flower_stats_cb() //timer
cxgb4_cleanup_tc_flower() | schedule_work()
del_timer_sync() |
| ch_flower_stats_handler() //workqueue
| mod_timer()
cancel_work_sync() |
kfree(adapter) //FREE | ch_flower_stats_cb() //timer
| adap->flower_stats_work //USE
This patch changes del_timer_sync() to timer_shutdown_sync(),
which could prevent rearming of the timer from the workqueue.

When the NIC is down, user set mac address or vlan tag to VF,
the xxx_set_vf_mac() or xxx_set_vf_vlan() will invoke efx_net_stop()
and efx_net_open(), since netif_running() is false, the port will not
start and keep port_enabled false, but selftest_work is scheduled
in efx_net_open().
If we remove the device before selftest_work run, the efx_stop_port()
will not be called since the NIC is down, and then efx is freed,
we will soon get a UAF in run_timer_softirq() like this:

If the NIC is not actually brought up, there is no need to schedule
selftest_work, so let's move invoking efx_selftest_async_start()
into efx_start_all(), and it will be canceled by broughting down.

Here we copy the data from the original buf to the new page. But we
not check that it may be overflow.
As long as the size received(including vnethdr) is greater than 3840
(PAGE_SIZE -VIRTIO_XDP_HEADROOM). Then the memcpy will overflow.
And this is completely possible, as long as the MTU is large, such
as 4096. In our test environment, this will cause crash. Since crash is
caused by the written memory, it is meaningless, so I do not include it.

Update API for bpf_xdp_metadata_rx_hash() with arg for xdp rss hash type.
The veth driver currently only support XDP-hints based on SKB code path.
The SKB have lost information about the RSS hash type, by compressing
the information down to a single bitfield skb->l4_hash, that only knows
if this was a L4 hash value.
In preparation for veth, the xdp_rss_hash_type have an L4 indication
bit that allow us to return a meaningful L4 indication when working
with SKB based packets.

The RSS hash type specifies what portion of packet data NIC hardware used
when calculating RSS hash value. The RSS types are focused on Internet
traffic protocols at OSI layers L3 and L4. L2 (e.g. ARP) often get hash
value zero and no RSS type. For L3 focused on IPv4 vs. IPv6, and L4
primarily TCP vs UDP, but some hardware supports SCTP.
Hardware RSS types are differently encoded for each hardware NIC. Most
hardware represent RSS hash type as a number. Determining L3 vs L4 often
requires a mapping table as there often isn't a pattern or sorting
according to ISO layer.
The patch introduce a XDP RSS hash type (enum xdp_rss_hash_type) that
contains both BITs for the L3/L4 types, and combinations to be used by
drivers for their mapping tables. The enum xdp_rss_type_bits get exposed
to BPF via BTF, and it is up to the BPF-programmer to match using these
defines.
This proposal change the kfunc API bpf_xdp_metadata_rx_hash() adding
a pointer value argument for provide the RSS hash type.
Change signature for all xmo_rx_hash calls in drivers to make it compile.
The RSS type implementations for each driver comes as separate patches.

For quite some time we were chasing a bug which looked like a sudden
permanent failure of networking and mmc on some of our devices.
The bug was very sensitive to any software changes and even more to
any kernel debug options.
Finally we got a setup where the problem was reproducible with
CONFIG_DMA_API_DEBUG=y and it revealed the issue with the rx dma:

Lars was fast to find an explanation: according to the datasheet
bit 2 of the rx buffer descriptor entry has a different meaning in the
extended mode:
Address [2] of beginning of buffer, or
in extended buffer descriptor mode (DMA configuration register [28] = 1),
indicates a valid timestamp in the buffer descriptor entry.
The macb driver didn't mask this bit while getting an address and it
eventually caused a memory corruption and a dma failure.
The problem is resolved by explicitly clearing the problematic bit
if hw timestamping is used.
Fixes: 7b4296148066 ("net: macb: Add support for PTP timestamps in DMA descriptors")

I have observed an issue where the RX direction of the LS1028A ENETC pMAC
seems unresponsive. The minimal procedure to reproduce the issue is:
1. Connect ENETC port 0 with a loopback RJ45 cable to one of the Felix
switch ports (0).
2. Bring the ports up (MAC Merge layer is not enabled on either end).
3. Send a large quantity of unidirectional (express) traffic from Felix
to ENETC. I tried altering frame size and frame count, and it doesn't
appear to be specific to either of them, but rather, to the quantity
of octets received. Lowering the frame count, the minimum quantity of
packets to reproduce relatively consistently seems to be around 37000
frames at 1514 octets (w/o FCS) each.
4. Using ethtool --set-mm, enable the pMAC in the Felix and in the ENETC
ports, in both RX and TX directions, and with verification on both
ends.
5. Wait for verification to complete on both sides.
6. Configure a traffic class as preemptible on both ends.
7. Send some packets again.
The issue is at step 5, where the verification process of ENETC ends
(meaning that Felix responds with an SMD-R and ENETC sees the response),
but the verification process of Felix never ends (it remains VERIFYING).
If step 3 is skipped or if ENETC receives less traffic than
approximately that threshold, the test runs all the way through
(verification succeeds on both ends, preemptible traffic passes fine).
If, between step 4 and 5, the step below is also introduced:
4.1. Disable and re-enable PM0_COMMAND_CONFIG bit RX_EN
then again, the sequence of steps runs all the way through, and
verification succeeds, even if there was the previous RX traffic
injected into ENETC.
Traffic sent *by* the ENETC port prior to enabling the MAC Merge layer
does not seem to influence the verification result, only received
traffic does.
The LS1028A manual does not mention any relationship between
PM0_COMMAND_CONFIG and MMCSR, and the hardware people don't seem to
know for now either.
The bit that is toggled to work around the issue is also toggled
by enetc_mac_enable(), called from phylink's mac_link_down() and
mac_link_up() methods - which is how the workaround was found:
verification would work after a link down/up.

TI CPSW uses of_platform_* functions which are declared in of_platform.h.
of_platform.h gets implicitly included by of_device.h, but that is going
to be removed soon. Nothing else depends on of_device.h so it can be
dropped. of_platform.h also implicitly includes platform_device.h, so
add an explicit include for it, too.

warn: missing unwind goto?
When dma_set_mask fails it directly returns without disabling pci
device and freeing ipc_pcie. Fix this my calling a correct goto label
As dma_set_mask returns either 0 or -EIO, we can use a goto label, as
it finally returns -EIO.
Add a set_mask_fail goto label which stands consistent with other goto
labels in this function..

Static code analyzer complains to unchecked return value.
The result of pci_reset_function() is unchecked.
Despite, the issue is on the FLR supported code path and in that
case reset can be done with pcie_flr(), the patch uses less invasive
approach by adding the result check of pci_reset_function().

iavf: fix racing in VLANs
Ahmed Zaki says:
This patchset mainly fixes a racing issue in the iavf where the number of
VLANs in the vlan_filter_list might be more than the PF limit. To fix that,
we get rid of the cvlans and svlans bitmaps and keep all the required info
in the list.
The second patch adds two new states that are needed so that we keep the
VLAN info while the interface goes DOWN:
-- DISABLE (notify PF, but keep the filter in the list)
-- INACTIVE (dev is DOWN, filter is removed from PF)
Finally, the current code keeps each state in a separate bit field, which
is error prone. The first patch refactors that by replacing all bits with
a single enum. The changes are minimal where each bit change is replaced
with the new state value.

The VLAN filters info is currently being held in a list and 2 bitmaps
(active_cvlans and active_svlans). We are experiencing some racing where
data is not in sync in the list and bitmaps. For example, the VLAN is
initially added to the list but only when the PF replies, it is added to
the bitmap. If a user adds many V2 VLANS before the PF responds:
while [ $((i++)) ]
ip l add l eth0 name eth0.$i type vlan id $i
we might end up with more VLAN list entries than the designated limit.
Also, The "ip link show" will show more links added than the PF limit.
On the other and, the bitmaps are only used to check the number of VLAN
filters and to re-enable the filters when the interface goes from DOWN to
UP.
This patch gets rid of the bitmaps and uses the list only. To do that,
the states of the VLAN filter are modified:
1 - IAVF_VLAN_REMOVE: the entry needs to be totally removed after informing
the PF. This is the "ip link del eth0.$i" path.
2 - IAVF_VLAN_DISABLE: (new) the netdev went down. The filter needs to be
removed from the PF and then marked INACTIVE.
3 - IAVF_VLAN_INACTIVE: (new) no PF filter exists, but the user did not
delete the VLAN.

The VLAN filter states are currently being saved as individual bits.
This is error prone as multiple bits might be mistakenly set.
Fix by replacing the bits with a single state enum. Also, add an
"ACTIVE" state for filters that are accepted by the PF.

If SFP module is not present, it is sensible to fail sfp_module_eeprom()
and sfp_module_eeprom_by_page() early to avoid excessive I2C transfers
which are garanteed to fail.
