This reverts commit 2dc2f760052da4925482ecdcdc5c94d4a599153c and
commit 6f73862fabd93213de157d9cc6ef76084311c628.
As discussed in the thread:
https://lore.kernel.org/all/f3c62ebe-7d59-c537-a010-bff366c8aeba@linaro.org/
the feature provided by commits 2dc2f760052da and 6f73862fabd93 is
actually already handled by the thermal framework via the cooling
device state aggregation, thus all this code is pointless.
The revert conflicts with the following changes:
- 7f4957be0d5b8: thermal: Use mode helpers in drivers
- 6a79507cfe94c: mlxsw: core: Extend thermal module with per QSFP module thermal zones
These conflicts were fixed and the resulting changes are in this patch.
Both reverts are in the same change as requested by Ido Schimmel:

VF was not able to send tagged traffic when it didn't
have any VLAN interfaces and VLAN anti-spoofing was enabled.
Fix this by allowing VFs with no VLAN filters to send tagged
traffic. After VF adds a VLAN interface it will be able to
send tagged traffic matching VLAN filters only.
Testing hints:
1. Spawn VF
2. Send tagged packet from a VF
3. The packet should be sent out and not dropped
4. Add a VLAN interface on VF
5. Send tagged packet on that VLAN interface
6. Packet should be sent out and not dropped
7. Send tagged packet with id different than VLAN interface
8. Packet should be dropped

Commit 1273f89578f2 ("ice: Fix broken IFF_ALLMULTI handling")
introduced new checks when setting/clearing promiscuous mode. But if the
requested promiscuous mode setting already exists, an -EEXIST error
message would be printed. This is incorrect because promiscuous mode is
either on/off and shouldn't print an error when the requested
configuration is already set.
This can happen when removing a bridge with two bonded interfaces and
promiscuous most isn't fully cleared from VLAN VSI in hardware.
Fix this by ignoring cases where requested promiscuous mode exists.

When at least two interfaces are bonded and a bridge is enabled on the
bond, an error can occur when the bridge is removed and re-added. The
reason for the error is because promiscuous mode was not fully cleared from
the VLAN VSI in the hardware. With this change, promiscuous mode is
properly removed when the bridge disconnects from bonding.

Ignore EEXIST error when setting promiscuous mode.
This fix is needed because the driver could set promiscuous mode
when it still has not cleared properly.
Promiscuous mode could be set only once, so setting it second

Avoid enabling or disabling VLAN 0 when trying to set promiscuous
VLAN mode if double VLAN mode is enabled. This fix is needed
because the driver tries to add the VLAN 0 filter twice (once for
inner and once for outer) when double VLAN mode is enabled. The
filter program is rejected by the firmware when double VLAN is
enabled, because the promiscuous filter only needs to be set once.
This issue was missed in the initial implementation of double VLAN
mode.

ice: detect and report PTP timestamp issues
Jacob Keller says:
This series fixes a few small issues with the cached PTP Hardware Clock
timestamp used for timestamp extension. It also introduces extra checks to
help detect issues with this logic, such as if the cached timestamp is not
updated within the 2 second window.
This introduces a few statistics similar to the ones already available in
other Intel drivers, including tx_hwtstamp_skipped and tx_hwtstamp_timeouts.
It is intended to aid in debugging issues we're seeing with some setups
which might be related to incorrect cached timestamp values.

If the PTP hardware clock is adjusted, the ice driver must update the
cached PHC timestamp. This is required in order to perform timestamp
extension on the shorter timestamps captured by the PHY.
Currently, we simply call ice_ptp_update_cached_phctime in the settime and
adjtime callbacks. This has a few issues:
1) if ICE_CFG_BUSY is set because another thread is updating the Rx rings,
we will exit with an error. This is not checked, and the functions do
not re-schedule the update. This could leave the cached timestamp
incorrect until the next scheduled work item execution.
2) even if we did handle an update, any currently outstanding Tx timestamp
would be extended using the wrong cached PHC time. This would produce
incorrect results.
To fix these issues, introduce a new ice_ptp_reset_cached_phctime function.
This function calls the ice_ptp_update_cached_phctime, and discards
outstanding Tx timestamps.
If the ice_ptp_update_cached_phctime function fails because ICE_CFG_BUSY is
set, we log a warning and schedule the thread to execute soon. The update
function is modified so that it always updates the cached copy in the PF
regardless. This ensures we have the most up to date values possible and
minimizes the risk of a packet timestamp being extended with the wrong
value.
It would be nice if we could skip reporting Rx timestamps until the cached
values are up to date. However, we can't access the Rx rings while
ICE_CFG_BUSY is set because they are actively being updated by another
thread.

A following change is going to want to make use of ice_ptp_flush_tx_tracker
earlier in the ice_ptp.c file. To make this work, move the Tx timestamp
tracking functions higher up in the file, and pull the
ice_ptp_update_cached_timestamp function below them. This should have no
functional change.

The ice driver requires a cached copy of the PHC time in order to perform
timestamp extension on Tx and Rx hardware timestamp values. This cached PHC
time must always be updated at least once every 2 seconds. Otherwise, the
math used to perform the extension would produce invalid results.
The updates are supposed to occur periodically in the PTP kthread work
item, which is scheduled to run every half second. Thus, we do not expect
an update to be delayed for so long. However, there are error conditions
which can cause the update to be delayed.
Track this situation by using jiffies to determine approximately how long
ago the last update occurred. Add a new statistic and a dev_warn when we
have failed to update the cached PHC time. This makes the error case more
obvious.

conditions which could cause these events are rare, but it can be useful to

When we create new Rx rings, the cached_phctime field is zero initialized.
This could result in incorrect timestamp reporting due to the cached value
not yet being updated. Although a background task will periodically update
the cached value, ensure it matches the existing cached value in the PF
structure at ring initialization.

When the user changes the number of queues via ethtool, the driver
allocates new rings. This allocation did not initialize tx_tstamps. This
results in the tx_tstamps field being zero (due to kcalloc allocation), and
would result in a NULL pointer dereference when attempting a transmit
timestamp on the new ring.

When a tx_timeout fires, the PF attempts to recover by incrementally
resetting. First we try a PFR, then CORER and finally a GLOBR. If the
GLOBR fails, then we keep hitting the tx_timeout and incrementing the
recovery level and issuing dmesgs, which is both annoying to the user
and accomplishes nothing.
If the GLOBR fails, then we're pretty much totally hosed, and there's
not much else we can do to recover, so this makes it such that we just
kill the VSI and stop hitting the tx_timeout in such a case.

Fix checksum offload on VXLAN tunnels.
In case, when mpls protocol is not used, set l4 header to transport
header of skb. This fixes case, when user tries to offload checksums
of VXLAN tunneled traffic.
Steps for reproduction (requires link partner with tunnels):
ip l s enp130s0f0 up
ip a f enp130s0f0
ip a a 10.10.110.2/24 dev enp130s0f0
ip l s enp130s0f0 mtu 1600
ip link add vxlan12_sut type vxlan id 12 group 238.168.100.100 dev \
enp130s0f0 dstport 4789
ip l s vxlan12_sut up
ip a a 20.10.110.2/24 dev vxlan12_sut
iperf3 -c 20.10.110.1 #should connect
Without this patch, TX descriptor was using wrong data, due to
l4 header pointing wrong address. NIC would then drop those packets
internally, due to incorrect TX descriptor data, which increased
GLV_TEPC register.

Commit 'c2ed5611afd7' has increased the cpl_t5_pass_accept_rpl{} structure
size by 8B to avoid roundup. cpl_t5_pass_accept_rpl{} is a HW specific
structure and increasing its size will lead to unwanted adapter errors.
Current commit reverts the cpl_t5_pass_accept_rpl{} back to its original
and allocates zeroed skb buffer there by avoiding the memset for iss field.
Reorder code to minimize chip type checks.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Currently mlxsw driver configures one global PTP configuration for all
ports. The reason is that the switch behaves like a transparent clock
between CPU port and front-panel ports. When time stamp is enabled in
any port, the hardware is configured to update the correction field. The
fact that the configuration of CPU port affects all the ports, makes the
correction field update to be global for all ports. Otherwise, user will
see odd values in the correction field, as the switch will update the
correction field in the CPU port, but not in all the front-panel ports.
The CPU port is relevant in both RX and TX, so to avoid problematic
configuration, forbid PTP enablement only in one direction, i.e., only in
RX or TX.
Without the change:
$ hwstamp_ctl -i swp1 -r 12 -t 0
current settings:
tx_type 0
rx_filter 0

Currently the functions mlxsw_sp2_ptp_{configure, deconfigure}_port()
assume that they are called when RTNL is locked and they warn otherwise.
The deconfigure function can be called when port is removed, for example
as part of device reload, then there is no locked RTNL and the function
warns [1].
To avoid such case, do not assume that RTNL protects this code, add a
dedicated mutex instead. The mutex protects 'ptp_state->config' which
stores the existing global configuration in hardware. Use this mutex also
to protect the code which configures the hardware. Then, there will be
only one configuration in any time, which will be updated in 'ptp_state'
and a race will be avoided.

Currently as part of removing port, PTP API is called to clear the
existing configuration and set the 'rx_filter' and 'tx_type' to zero.
The clearing is done before unregistering the netdevice, which means that

In case that 'CONFIG_PTP_1588_CLOCK' is not enabled in the config file,
there are implementations for the functions
mlxsw_{sp,sp2}_ptp_txhdr_construct() as part of 'spectrum_ptp.h'. In this
case, they should be defined as 'static' as they are not supposed to be
used out of this file. Make the functions 'static', otherwise the following
warnings are returned:
"warning: no previous prototype for 'mlxsw_sp_ptp_txhdr_construct'"
"warning: no previous prototype for 'mlxsw_sp2_ptp_txhdr_construct'"
In addition, make the functions 'inline' for case that 'spectrum_ptp.h'
will be included anywhere else and the functions would probably not be
used, so compilation warnings about unused static will be returned.

Fix deadlock that occurs when iavf interface is a part of failover
configuration.
1. Mutex crit_lock is taken at the beginning of iavf_watchdog_task()
2. Function iavf_init_config_adapter() is called when adapter
state is __IAVF_INIT_CONFIG_ADAPTER
3. iavf_init_config_adapter() calls register_netdevice() that emits
NETDEV_REGISTER event
4. Notifier function failover_event() then calls
net_failover_slave_register() that calls dev_open()
5. dev_open() calls iavf_open() that tries to take crit_lock in
end-less loop

Do not call iavf_close in iavf_reset_task error handling. Doing so can
lead to double call of napi_disable, which can lead to deadlock there.
Removing VF would lead to iavf_remove task being stuck, because it
requires crit_lock, which is held by iavf_close.
Call iavf_disable_vf if reset fail, so that driver will clean up
remaining invalid resources.
During rapid VF resets, HW can fail to setup VF mailbox. Wrong
error handling can lead to iavf_remove being stuck with:

Fix possible NULL pointer dereference, due to freeing of adapter->vf_res
in iavf_init_get_resources. Previous commit introduced a regression,
where receiving IAVF_ERR_ADMIN_QUEUE_NO_WORK from iavf_get_vf_config
would free adapter->vf_res. However, netdev is still registered, so
ethtool_ops can be called. Calling iavf_get_link_ksettings with no vf_res,
will result with:

Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, bpf, can and netfilter.
A little larger than usual but it's all fixes, no late features. It's
large partially because of timing, and partially because of follow ups
to stuff that got merged a week or so before the merge window and
wasn't as widely tested. Maybe the Bluetooth fixes are a little
alarming so we'll address that, but the rest seems okay and not scary.
Notably we're including a fix for the netfilter Kconfig [1], your WiFi
warning [2] and a bluetooth fix which should unblock syzbot [3].
Current release - regressions:
- Bluetooth:
- don't try to cancel uninitialized works [3]
- L2CAP: fix use-after-free caused by l2cap_chan_put
- tls: rx: fix device offload after recent rework
- devlink: fix UAF on failed reload and leftover locks in mlxsw
Current release - new code bugs:
- netfilter:
- flowtable: fix incorrect Kconfig dependencies [1]
- nf_tables: fix crash when nf_trace is enabled
- bpf:
- use proper target btf when exporting attach_btf_obj_id
- arm64: fixes for bpf trampoline support
- Bluetooth:
- ISO: unlock on error path in iso_sock_setsockopt()
- ISO: fix info leak in iso_sock_getsockopt()
- ISO: fix iso_sock_getsockopt for BT_DEFER_SETUP
- ISO: fix memory corruption on iso_pinfo.base
- ISO: fix not using the correct QoS
- hci_conn: fix updating ISO QoS PHY
- phy: dp83867: fix get nvmem cell fail
Previous releases - regressions:
- wifi: cfg80211: fix validating BSS pointers in
__cfg80211_connect_result [2]
- atm: bring back zatm uAPI after ATM had been removed
- properly fix old bug making bonding ARP monitor mode not being able
to work with software devices with lockless Tx
- tap: fix null-deref on skb->dev in dev_parse_header_protocol
- revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP" it helps some
devices and breaks others
- netfilter:
- nf_tables: many fixes rejecting cross-object linking which may
lead to UAFs
- nf_tables: fix null deref due to zeroed list head
- nf_tables: validate variable length element extension
- bgmac: fix a BUG triggered by wrong bytes_compl
- bcmgenet: indicate MAC is in charge of PHY PM
Previous releases - always broken:
- bpf:
- fix bad pointer deref in bpf_sys_bpf() injected via test infra
- disallow non-builtin bpf programs calling the prog_run command
- don't reinit map value in prealloc_lru_pop
- fix UAFs during the read of map iterator fd
- fix invalidity check for values in sk local storage map
- reject sleepable program for non-resched map iterator
- mptcp:

area_cache_get() is used to distribute cache->area and set cache->id,
and if cache->id is not 0 and cache->area->kref refcount is 0, it will
release the cache->area by nfp_cpp_area_release(). area_cache_get()
set cache->id before cpp->op->area_init() and nfp_cpp_area_acquire().
But if area_init() or nfp_cpp_area_acquire() fails, the cache->id is
is already set but the refcount is not increased as expected. At this
time, calling the nfp_cpp_area_release() will cause use-after-free.
To avoid the use-after-free, set cache->id after area_init() and
nfp_cpp_area_acquire() complete successfully.
Note: This vulnerability is triggerable by providing emulated device
equipped with specified configuration.

Remove WARN_ON() from check if VSI is null in ice_reset_vf.
Add "VF is already removed\n" in dev_dbg().
This WARN_ON() is unnecessary and causes call trace, despite that
call trace, driver still works. There is no need for this warn
because this piece of code is responsible for disabling VF's Tx/Rx
queues when VF is disabled, but when VF is already removed there
is no need to do reset or disable queues.

In commit b03d519d3460 ("ice: store VF pointer instead of VF ID")
WARN_ON checks were added to validate the vsi->vf pointer and
catch programming errors. However, one check to vsi->vf was missed.
This caused a call trace when resetting VFs.
Fix ice_vsi_rebuild by encompassing VF pointer in WARN_ON check.

Currently, tls_device_down synchronizes with tls_device_resync_rx using
RCU, however, the pointer to netdev is stored using WRITE_ONCE and
loaded using READ_ONCE.
Although such approach is technically correct (rcu_dereference is
essentially a READ_ONCE, and rcu_assign_pointer uses WRITE_ONCE to store
NULL), using special RCU helpers for pointers is more valid, as it
includes additional checks and might change the implementation
transparently to the callers.
Mark the netdev pointer as __rcu and use the correct RCU helpers to
access it. For non-concurrent access pass the right conditions that
guarantee safe access (locks taken, refcount value). Also use the
correct helper in mlx5e, where even READ_ONCE was missing.
The transition to RCU exposes existing issues, fixed by this commit:
1. bond_tls_device_xmit could read netdev twice, and it could become
NULL the second time, after the NULL check passed.
2. Drivers shouldn't stop processing the last packet if tls_device_down
just set netdev to NULL, before tls_dev_del was called. This prevents a
possible packet drop when transitioning to the fallback software mode.

According to Guillaume Nault RT_TOS should never be used for IPv6.
Quote:
RT_TOS() is an old macro used to interprete IPv4 TOS as described in
the obsolete RFC 1349. It's conceptually wrong to use it even in IPv4
code, although, given the current state of the code, most of the
existing calls have no consequence.
But using RT_TOS() in IPv6 code is always a bug: IPv6 never had a "TOS"
field to be interpreted the RFC 1349 way. There's no historical
compatibility to worry about.

and netdev_sent_queue() we can hit the BUG_ON as bgmac_dma_tx_free()
can miscalculate the queue size while called from bgmac_poll().
The machine which triggered the BUG runs a v4.14 RT kernel - but the issue
seems present in mainline too.

If tsnep_tx_map() fails, then tsnep_tx_unmap() shall start at the write
index like tsnep_tx_map(). This is different to the normal operation.
Thus, add an additional parameter to tsnep_tx_unmap() to enable start at
different positions for successful TX and failed TX.

Kernel test robot found the following warning:
drivers/net/ethernet/engleder/tsnep_main.c:1254:34: warning:
'tsnep_of_match' defined but not used [-Wunused-const-variable=]
of_match_ptr() compiles into NULL if CONFIG_OF is disabled.
tsnep_of_match exists always so use of of_match_ptr() is useless.
Fix warning by dropping of_match_ptr().

Avoid the PHY library call unnecessarily into the suspend/resume functions by
setting phydev->mac_managed_pm to true. The GENET driver essentially does
exactly what mdio_bus_phy_resume() does by calling phy_init_hw() plus
phy_resume().
