Pull x86 fixes from Borislav Petkov:
"There's a little bit more 'movement' in there for my taste but it
needs to happen and should make the code better after it.
- Check cmdline_find_option()'s return value before further
processing
- Clear temporary storage in the resctrl code to prevent access to an
unexistent MSR
- Add a simple throttling mechanism to protect the hypervisor from
potentially malicious SEV guests issuing requests in rapid
succession.
In order to not jeopardize the sanity of everyone involved in
maintaining this code, the request issuing side has received a
cleanup, split in more or less trivial, small and digestible
pieces. Otherwise, the code was threatening to become an
unmaintainable mess.
Therefore, that cleanup is marked indirectly also for stable so
that there's no differences between the upstream code and the
stable variant when it comes down to backporting more there"

The __find_restype() function loops over the m5mols_default_ffmt[]
array, and the termination condition ends up being wrong: instead of
stopping when the iterator becomes the size of the array it traverses,
it stops after it has already overshot the array.
Now, in practice this doesn't likely matter, because the code will
always find the entry it looks for, and will thus return early and never
hit that last extra iteration.
But it turns out that clang will unroll the loop fully, because it has
only two iterations (well, three due to the off-by-one bug), and then
clang will end up just giving up in the middle of the loop unrolling
when it notices that the code walks past the end of the array.
And that made 'objtool' very unhappy indeed, because the generated code
just falls off the edge of the universe, and ends up falling through to
the next function, causing this warning:
drivers/media/i2c/m5mols/m5mols.o: warning: objtool: m5mols_set_fmt() falls through to next function m5mols_get_frame_desc()
Fix the loop ending condition.

Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, wifi and ipsec.
A little more changes than usual, but it's pretty normal for us that
the rc3/rc4 PRs are oversized as people start testing in earnest.

more of an unscientific hunch.
Current release - regressions:
- phy: mscc: fix deadlock in phy_ethtool_{get,set}_wol()
- virtio: vsock: don't use skbuff state to account credit

- dsa: mv88e6xxx: fix max_mtu of 1492 on 6165, 6191, 6220, 6250, 6290
Previous releases - always broken:
- tcp: tcp_make_synack() can be called from process context, don't
assume preemption is disabled when updating stats
- netfilter: correct length for loading protocol registers
- virtio_net: add checking sq is full inside xdp xmit
- bonding: restore IFF_MASTER/SLAVE flags on bond enslave Ethertype
change

syzbot reported a warning[1] where the bond device itself is a slave and
we try to enslave a non-ethernet device as the first slave which fails
but then in the error path when ether_setup() restores the bond device
it also clears all flags. In my previous fix[2] I restored the
IFF_MASTER flag, but I didn't consider the case that the bond device
itself might also be a slave with IFF_SLAVE set, so we need to restore
that flag as well. Use the bond_ether_setup helper which does the right
thing and restores the bond's flags properly.
Steps to reproduce using a nlmon dev:
$ ip l add nlmon0 type nlmon
$ ip l add bond1 type bond
$ ip l add bond2 type bond
$ ip l set bond1 master bond2
$ ip l set dev nlmon0 master bond1
$ ip -d l sh dev bond1
22: bond1: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noqueue master bond2 state DOWN mode DEFAULT group default qlen 1000
(now bond1's IFF_SLAVE flag is gone and we'll hit a warning[3] if we
try to delete it)

Add bond_ether_setup helper which is used to fix ether_setup() calls in the
bonding driver. It takes care of both IFF_MASTER and IFF_SLAVE flags, the
former is always restored and the latter only if it was set.
If the bond enslaves non-ARPHRD_ETHER device (changes its type), then
releases it and enslaves ARPHRD_ETHER device (changes back) then we
use ether_setup() to restore the bond device type but it also resets its
flags and removes IFF_MASTER and IFF_SLAVE[1]. Use the bond_ether_setup
helper to restore both after such transition.
[1] reproduce (nlmon is non-ARPHRD_ETHER):
$ ip l add nlmon0 type nlmon
$ ip l add bond2 type bond mode active-backup
$ ip l set nlmon0 master bond2
$ ip l set nlmon0 nomaster
$ ip l add bond1 type bond
(we use bond1 as ARPHRD_ETHER device to restore bond2's mode)
$ ip l set bond1 master bond2
$ ip l sh dev bond2
37: bond2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

A recent commit defined HW_PARAM_4 as a GSI register ID but did not
add it to gsi_reg_id_valid() to indicate it's valid (for IPA v5.0+).
Add version checks for the HW_PARAM_2 and INTER_EE IRQ GSI registers
there as well.
IPA v5.0 supports up to 8 source and destination resource groups.
Update the validity check (and the comments where the register IDs
are defined) to reflect that. Similarly update comments and
validity checks for the hash/cache-related registers.
Note that this patch fixes an omission and constrains things
further, but these don't technically represent bugs.

A recent commit defined a few IPA registers used for IPA v5.0+.
One of those was a mistake. Although the filter and router caches
get *flushed* using a single register, they use distinct registers
(ENDP_FILTER_CACHE_CFG and ENDP_ROUTER_CACHE_CFG) for configuration.
And although there *exists* a FILT_ROUT_CACHE_CFG register, it is
not needed in upstream code. So get rid of definitions related to
FILT_ROUT_CACHE_CFG, because they are not needed.

The blamed commit has replaced a ksz_write8() call to address
REG_PORT_5_CTRL_6 (0x56) with a ksz_set_xmii() -> ksz_pwrite8() call to
regs[P_XMII_CTRL_1], which is also defined as 0x56 for ksz8795_regs[].
The trouble is that, when compared to ksz_write8(), ksz_pwrite8() also
adjusts the register offset with the port base address. So in reality,
ksz_pwrite8(offset=0x56) accesses register 0x56 + 0x50 = 0xa6, which in
this switch appears to be unmapped, and the RGMII delay configuration on
the CPU port does nothing.
So if the switch wasn't fine with the RGMII delay configuration done
through pin strapping and relied on Linux to apply a different one in
order to pass traffic, this is now broken.
Using the offset translation logic imposed by ksz_pwrite8(), the correct
value for regs[P_XMII_CTRL_1] should have been 0x6 on ksz8795_regs[], in
order to really end up accessing register 0x56.
Static code analysis shows that, despite there being multiple other
accesses to regs[P_XMII_CTRL_1] in this driver, the only code path that
is applicable to ksz8795_regs[] and ksz8_dev_ops is ksz_set_xmii().
Therefore, the problem is isolated to RGMII delays.
In its current form, ksz8795_regs[] contains the same value for
P_XMII_CTRL_0 and for P_XMII_CTRL_1, and this raises valid suspicions
that writes made by the driver to regs[P_XMII_CTRL_0] might overwrite
writes made to regs[P_XMII_CTRL_1] or vice versa.
Again, static analysis shows that the only accesses to P_XMII_CTRL_0
from the driver are made from code paths which are not reachable with
ksz8_dev_ops. So the accesses made by ksz_set_xmii() are safe for this
switch family.

The aq_xdp_run_prog() function falls back to the XDP_ABORTED action
handler (using a goto) if the operations for any of the other actions fail.
The XDP_ABORTED handler in turn calls the bpf_warn_invalid_xdp_action()
tracepoint. However, the function also jumps into the XDP_PASS helper if no
XDP program is loaded on the device, which means the XDP_ABORTED handler
can be run with a NULL program pointer. This results in a NULL pointer
deref because the tracepoint dereferences the 'prog' pointer passed to it.
This situation can happen in multiple ways:
- If a packet arrives between the removal of the program from the interface
and the static_branch_dec() in aq_xdp_setup()
- If there are multiple devices using the same driver in the system and
one of them has an XDP program loaded and the other does not.
Fix this by refactoring the aq_xdp_run_prog() function to remove the 'goto
pass' handling if there is no XDP program loaded. Instead, factor out the
skb building in a separate small helper function.

It is preferred to use typed property access functions (i.e.

of_get_property/of_find_property functions for reading properties.
Convert reading boolean properties to of_property_read_bool().

There are 3 classes of switch families that the driver is aware of, as
far as mv88e6xxx_change_mtu() is concerned:
- MTU configuration is available per port. Here, the
chip->info->ops->port_set_jumbo_size() method will be present.
- MTU configuration is global to the switch. Here, the
chip->info->ops->set_max_frame_size() method will be present.
- We don't know how to change the MTU. Here, none of the above methods
will be present.
Switch families MV88E6165, MV88E6191, MV88E6220, MV88E6250 and MV88E6290
fall in category 3.
The blamed commit has adjusted the MTU for all 3 categories by EDSA_HLEN
(8 bytes), resulting in a new maximum MTU of 1492 being reported by the
driver for these switches.
I don't have the hardware to test, but I do have a MV88E6390 switch on
which I can simulate this by commenting out its .port_set_jumbo_size
definition from mv88e6390_ops. The result is this set of messages at
probe time:
mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 1
mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 2
mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 3
mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 4
mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 5
mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 6
mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 7
mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 8
It is highly implausible that there exist Ethernet switches which don't
support the standard MTU of 1500 octets, and this is what the DSA
framework says as well - the error comes from dsa_slave_create() ->
dsa_slave_change_mtu(slave_dev, ETH_DATA_LEN).
But the error messages are alarming, and it would be good to suppress
them.
As a consequence of this unlikeliness, we reimplement mv88e6xxx_get_max_mtu()
and mv88e6xxx_change_mtu() on switches from the 3rd category as follows:
the maximum supported MTU is 1500, and any request to set the MTU to a
value larger than that fails in dev_validate_mtu().

ice_qp_dis() intends to stop a given queue pair that is a target of xsk
pool attach/detach. One of the steps is to disable interrupts on these
queues. It currently is broken in a way that txq irq is turned off
*after* HW flush which in turn takes no effect.
ice_qp_dis():
-> ice_qvec_dis_irq()
--> disable rxq irq
--> flush hw
-> ice_vsi_stop_tx_ring()
-->disable txq irq
Below splat can be triggered by following steps:
- start xdpsock WITHOUT loading xdp prog
- run xdp_rxq_info with XDP_TX action on this interface
- start traffic
- terminate xdpsock

In fact, irqs were not disabled and napi managed to be scheduled and run
while xsk_pool pointer was still valid, but SW ring of xdp_buff pointers
was already freed.
To fix this, call ice_qvec_dis_irq() after ice_vsi_stop_tx_ring(). Also
while at it, remove redundant ice_clean_rx_ring() call - this is handled
in ice_qp_clean_rings().
