[ Upstream commit 429205da6c834447a57279af128bdd56ccd5225e ]
Based on tests the QCA7000 doesn't support checksum offloading. So assume
ip_summed is CHECKSUM_NONE and let the kernel take care of the checksum
handling. This fixes data transfer issues in noisy environments.

[ Upstream commit c66070125837900163b81a03063ddd657a7e9bfb ]
The reference counting issue happens in one exception handling path of
cbq_change_class(). When failing to get tcf_block, the function forgets
to decrease the refcount of "rtab" increased by qdisc_put_rtab(),
causing a refcount leak.
Fix this issue by jumping to "failure" label when get tcf_block failed.

[ Upstream commit ca49bfd90a9dde175d2929dc1544b54841e33804 ]
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).

[ Upstream commit aaa8e4922c887ff47ad66ef918193682bccc1905 ]
These checks are still not strict enough. The main problem is that if
"cb->type == QRTR_TYPE_NEW_SERVER" is true then "len - hdrlen" is
guaranteed to be 4 but we need to be at least 16 bytes. In fact, we
can reject everything smaller than sizeof(*pkt) which is 20 bytes.
Also I don't like the ALIGN(size, 4). It's better to just insist that
data is needs to be aligned at the start.

[ Upstream commit 67d6d681e15b578c1725bad8ad079e05d1c48a8e ]
Even after commit 6457378fe796 ("ipv4: use siphash instead of Jenkins in
fnhe_hashfun()"), an attacker can still use brute force to learn
some secrets from a victim linux host.
One way to defeat these attacks is to make the max depth of the hash
table bucket a random value.
Before this patch, each bucket of the hash table used to store exceptions
could contain 6 items under attack.
After the patch, each bucket would contains a random number of items,
between 6 and 10. The attacker can no longer infer secrets.
This is slightly increasing memory size used by the hash table,
by 50% in average, we do not expect this to be a problem.
This patch is more complex than the prior one (IPv6 equivalent),
because IPv4 was reusing the oldest entry.
Since we need to be able to evict more than one entry per
update_or_create_fnhe() call, I had to replace
fnhe_oldest() with fnhe_remove_oldest().
Also note that we will queue extra kfree_rcu() calls under stress,
which hopefully wont be a too big issue.

[ Upstream commit b63aed3ff195130fef12e0af590f4838cf0201d8 ]
kmemleak reported that dev_name() of internally-handled cores were leaked
on driver unbinding. Let's use device_initialize() to take refcounts for
them and put_device() to properly free the related stuff.
While looking at it, there's another potential issue for those which should
be *registered* into driver core. If device_register() failed, we put
device once and freed bcma_device structures. In bcma_unregister_cores(),
they're treated as unregistered and we hit both UAF and double-free. That
smells not good and has also been fixed now.

driver probe list
[ Upstream commit 0d55649d2ad7296acfda9127e1d05518d025734a ]
Enabling interrupts via device tree for the internal PHYs on the
mv88e6390 DSA switch does not work. The driver insists to use poll mode.
Stage one debugging shows that the fwnode_mdiobus_phy_device_register
function calls fwnode_irq_get properly, and phy->irq is set to a valid
interrupt line initially.
But it is then cleared.
Stage two debugging shows that it is cleared here:
phy_probe:
/* Disable the interrupt if the PHY doesn't support it
* but the interrupt is still a valid one
*/
if (!phy_drv_supports_irq(phydrv) && phy_interrupt_is_valid(phydev))
phydev->irq = PHY_POLL;
Okay, so does the "Marvell 88E6390 Family" PHY driver not have the
.config_intr and .handle_interrupt function pointers? Yes it does.
Stage three debugging shows that the PHY device does not attempt a probe
against the "Marvell 88E6390 Family" driver, but against the "mv88x3310"
driver.
Okay, so why does the "mv88x3310" driver match on a mv88x6390 internal
PHY? The PHY IDs (MARVELL_PHY_ID_88E6390_FAMILY vs
MARVELL_PHY_ID_88X3310) are way different.
Stage four debugging has us looking through:
phy_device_register
-> device_add
-> bus_probe_device
-> device_initial_probe
-> __device_attach
-> bus_for_each_drv
-> driver_match_device
-> drv->bus->match
-> phy_bus_match
Okay, so as we said, the MII_PHYSID1 of mv88e6390 does not match the
mv88x3310 driver's PHY mask & ID, so why would phy_bus_match return...
Ahh, phy_bus_match calls a shortcircuit method,
phydrv->match_phy_device, and does not even bother to compare the PHY ID
if that is implemented.
So of course, we go inside the marvell10g.c driver and sure enough, it
implements .match_phy_device and does not bother to check the PHY ID.
What's interesting though is that at the end of the device_add() from
phy_device_register(), the driver for the internal PHYs _is_ the proper
"Marvell 88E6390 Family". This is because "mv88x3310" ends up failing to
probe after all, and __device_attach_driver(), to quote:
/*
* Ignore errors returned by ->probe so that the next driver can try
* its luck.
*/
The next (and only other) driver that matches is the 6390 driver. For
this one, phy_probe doesn't fail, and everything expects to work as
normal, EXCEPT phydev->irq has already been cleared by the previous
unsuccessful probe of a driver which did not implement PHY interrupts,
and therefore cleared that IRQ.
Okay, so it is not just Marvell 6390 that has PHY interrupts broken.
Stuff like Atheros, Aquantia, Broadcom, Qualcomm work because they are
lexicographically before Marvell, and stuff like NXP, Realtek, Vitesse
are broken.
This goes to show how fragile it is to reset phydev->irq = PHY_POLL from
the actual beginning of phy_probe itself. That seems like an actual bug
of its own too, since phy_probe has side effects which are not restored
on probe failure, but the line of thought probably was, the same driver
will attempt probe again, so it doesn't matter. Well, looks like it
does.
Maybe it would make more sense to move the phydev->irq clearing after
the actual device_add() in phy_device_register() completes, and the
bound driver is the actual final one.
(also, a bit frightening that drivers are permitted to bypass the MDIO
bus matching in such a trivial way and perform PHY reads and writes from
the .match_phy_device method, on devices that do not even belong to
them. In the general case it might not be guaranteed that the MDIO
accesses one driver needs to make to figure out whether to match on a
device is safe for all other PHY devices)

[ Upstream commit b357d9717be7f95fde2c6c4650b186a995b71e59 ]
commit 3ba7f53f8bf1 ("ice: don't remove netdev->dev_addr from uc sync
list") introduced calls to netif_addr_lock_bh() and
netif_addr_unlock_bh() in the driver's ndo_set_mac() callback. This is
fine since the driver is updated the netdev's dev_addr, but since this
is a spinlock, the driver cannot sleep when the lock is held.
Unfortunately the functions to add/delete MAC filters depend on a mutex.
This was causing a trace with the lock debug kernel config options
enabled when changing the mac address via iproute.

When we enabled auxiliary input/output support for the E810 device, we
forgot to add logic to restart the output when we change time. This is
important as the periodic output will be incorrect after a time change
otherwise.
This unfortunately includes the adjust time function, even though it
uses an atomic hardware interface. The atomic adjustment can still cause
the pin output to stall permanently, so we need to stop and restart it.
Introduce wrapper functions to temporarily disable and then re-enable
the clock outputs.

load the Tx rings and set the ptp_tx field, but we iterate over the

If the number of Tx and Rx queues differ, this could either cause
a buffer overrun when accessing the tx_rings list if num_txq is greater
than num_rxq, or it could cause us to fail to enable Tx timestamps for
some rings.
This was not noticed originally as we generally have the same number of

If link aggregation is used within stack devices driver rejects encap
rules if PF of the VF tunnel device is down. This happens because route
resolved for other PF and its eswitch instance is used to determine
correct vport.
To fix that use devcom feature to retrieve other eswitch instance if

When handling FIB_EVENT_ENTRY_REPLACE event for a new multipath route,
lag activation can be missed if a stale (struct lag_mp)->mfi pointer
exists, which was associated with an older multipath route that had been
removed.
Normally, when a route is removed, it triggers mlx5_lag_fib_event(),
which handles FIB_EVENT_ENTRY_DEL and clears mfi pointer. But, if
mlx5_lag_check_prereq() condition isn't met, for example when eswitch is
in legacy mode, the fib event is skipped and mfi pointer becomes stale.
Fix by resetting mfi pointer to NULL in mlx5_deactivate_lag().

The irqs are requested in 'wcd9335_setup_irqs()' using a resource managed

'wcd9335_setup_irqs()' requests all what is defined in the 'wcd9335_irqs'

read overflows if a source string is not NUL-terminated.
Also, the strnlen() call does not avoid the read overflow in the strlcpy

So, replace this block by a call to kstrndup() that avoids this type of
overflow and does the same.

receive buffer
[ Upstream commit 9d68cd9120e4e3af38f843e165631c323b86b4e4 ]
Commit adae1e931acd ("Drivers: hv: vmbus: Copy packets sent by Hyper-V out
of the ring buffer") introduced a notion of maximum packet size and for
KVM and FCOPY drivers set it to the length of the receive buffer. VSS
driver wasn't updated, this means that the maximum packet size is now
VMBUS_DEFAULT_MAX_PKT_SIZE (4k). Apparently, this is not enough. I'm
observing a packet of 6304 bytes which is being truncated to 4096. When
VSS driver tries to read next packet from ring buffer it starts from the
wrong offset and receives garbage.
Set the maximum packet size to 'HV_HYP_PAGE_SIZE * 2' in VSS driver. This
matches the length of the receive buffer and is in line with other utils
drivers.

[ Upstream commit d7af7e497f0308bc97809cc48b58e8e0f13887e1 ]
Fix a verifier bug found by smatch static checker in [0].
This problem has never been seen in prod to my best knowledge. Fixing it
still seems to be a good idea since it's hard to say for sure whether
it's possible or not to have a scenario where a combination of
convert_ctx_access() and a narrow load would lead to an out of bound
write.
When narrow load is handled, one or two new instructions are added to
insn_buf array, but before it was only checked that
cnt >= ARRAY_SIZE(insn_buf)
And it's safe to add a new instruction to insn_buf[cnt++] only once. The
second try will lead to out of bound write. And this is what can happen
if `shift` is set.
Fix it by making sure that if the BPF_RSH instruction has to be added in
addition to BPF_AND then there is enough space for two more instructions
in insn_buf.

[ Upstream commit e6d0b92ac00b53121a35b2a1ce8d393dc9179fdf ]
This patch reverts commit acbf58e53041 ("ASoC: wm_adsp: Let
soc_cleanup_component_debugfs remove debugfs"), and adds an
alternate solution to the issue. That patch removes the call to
debugfs_remove_recursive, which cleans up the DSPs debugfs. The
intention was to avoid an unbinding issue on an out of tree
driver/platform.
The issue with the patch is it means the driver no longer cleans up
its own debugfs, instead relying on ASoC to remove recurive on the
parent debugfs node. This is conceptually rather unclean, but also it
would prevent DSPs being added/removed independently of ASoC and soon
we are going to be upstreaming some non-audio parts with these DSPs,
which will require this.
Finally, it seems the issue on the platform is a result of the
wm_adsp2_cleanup_debugfs getting called twice. This is very likely a
problem on the platform side and will be resolved there. But in the mean
time make the code a little more robust to such issues, and again
conceptually a bit nicer, but clearing the debugfs_root variable in the
DSP structure when the debugfs is removed.

dst_port_window_size. If these are left uninitialized, it can cause DMA
failures at least if external TI SDMA is ever configured for sdhci.
For other external DMA cases, this is probably not currently an issue but
is still good to fix though.

[ Upstream commit e8b374b649afe756c2470e0e6668022e90bf8518 ]
Module configuration may differ between its instances depending on
resources required and input and output audio format. Available
parameters to select from are stored in module resource and interface
(format) lists. These come from topology, together with description of
each of pipe's modules.
Ignoring index value provided by topology and relying always on 0th
entry leads to unexpected module behavior due to under/overbudged
resources assigned or impropper format selection. Fix by taking entry at
index specified by topology.

Otherthan setting action as RSS in NPC MCAM entry, RSS flowkey
algorithm index also needs to be set. Otherwise whatever algorithm
is defined at flowkey index '0' will be considered by HW and pkt
flows will be distributed as such.
Fix this by saving the flowkey index sent by admin function while
initializing RSS and then use it when framing MCAM rules.

[ Upstream commit 05209e3570e452cdaa644e8398a8875b6a91051d ]
Whenever user changes interface MAC address both default DMAC based
MCAM rule and VLAN offload (for strip) rules are updated with new
MAC address. To update or install VLAN offload rule PF driver needs
interface's receive channel info, which is retrieved from admin
function at the time of NIXLF initialization.
If user changes MAC address before interface is UP, VLAN offload rule
installation will fail and throw error as receive channel is not valid.
To avoid this, skip VLAN offload rule installation if netdev is not UP.
This rule will anyway be reinslatted as part of open() call.

As per hardware the base channel number configured
for programmable channels of a block must be multiple
of number of channels of that block. This condition
is not met for SDP base channel currently. Hence this
patch ensures all the base channel numbers of all
blocks are multiple of number of channels present in
the blocks. Also instead of hardcoding SDP number
of channels the same is read from the NIX_AF_CONST1
register.
