Networking fixes for 5.10-rc6, including fixes from the WiFi driver,
and can subtrees.
Current release - regressions:
- gro_cells: reduce number of synchronize_net() calls
- ch_ktls: release a lock before jumping to an error path
Current release - always broken:
- tcp: Allow full IP tos/IPv6 tclass to be reflected in L3 header
Previous release - regressions:
- net/tls: fix missing received data after fast remote close
- vsock/virtio: discard packets only when socket is really closed
- sock: set sk_err to ee_errno on dequeue from errq
- cxgb4: fix the panic caused by non smac rewrite
Previous release - always broken:
- tcp: fix corner cases around setting ECN with BPF selection
of congestion control
- tcp: fix race condition when creating child sockets from
syncookies on loopback interface
- usbnet: ipheth: fix connectivity with iOS 14
- tun: honor IOCB_NOWAIT flag
- net/packet: fix packet receive on L3 devices without visible
hard header
- devlink: Make sure devlink instance and port are in same net
namespace
- net: openvswitch: fix TTL decrement action netlink message format
- bonding: wait for sysfs kobject destruction before freeing
struct slave
- net: stmmac: fix upstream patch applied to the wrong context
- bnxt_en: fix return value and unwind in probe error paths
Misc:
- devlink: add extra layer of categorization to the reload stats
uAPI before it's released

Pull drm fixes from Dave Airlie:
"Unfortunately this has a bit of thanksgiving stuffing in it, as it a
bit larger (at least the vc4 patches) than I like at this point in
time.
The main thing is it has a bunch of regressions fixes for reports in
the last couple of weeks, ast, nouveau and the amdgpu ttm init fix,
along with the usual selection of amdgpu and i915 fixes.
The vc4 fixes are a few but they are fixes and the nastiest one is a
fix for when you have a 2.4Ghz Wifi and a HDMI signal with a clock in
that range and there isn't enough shielding and interference happen
between the two, the fix adjusts the mode clock to try and avoid the
wifi channels in that case.
Hopefully you can merge this between turkey slices, and next week
should be quieter.

net: openvswitch: fix TTL decrement action netlink message format
Currently, the openvswitch module is not accepting the correctly formated
netlink message for the TTL decrement action. For both setting and getting
the dec_ttl action, the actions should be nested in the
OVS_DEC_TTL_ATTR_ACTION attribute as mentioned in the openvswitch.h uapi.
When the original patch was sent, it was tested with a private OVS userspace
implementation. This implementation was unfortunately not upstreamed and
reviewed, hence an erroneous version of this patch was sent out.
Leaving the patch as-is would cause problems as the kernel module could
interpret additional attributes as actions and vice-versa, due to the
actions not being encapsulated/nested within the actual attribute, but
being concatinated after it.
Fixes:

"The main changes are relating to our handling of access/dirty bits,
where our low-level page-table helpers could lead to stale young
mappings and loss of the dirty bit in some cases (the latter has not
been observed in practice, but could happen when clearing "soft-dirty"
if we enabled that). These were posted as part of a larger series, but
the rest of that is less urgent and needs a v2 which I'll get to
shortly.
In other news, we've now got a set of fixes to resolve the
lockdep/tracing problems that have been plaguing us for a while, but
they're still a bit "fresh" and I plan to send them to you next week
after we've got some more confidence in them (although initial CI
results look good).

perf stat: Use proper cpu for shadow stats
Currently perf stat shows some metrics (like IPC) for defined events.
But when no aggregation mode is used (-A option), it shows incorrect
values since it used a value from a different cpu.
Before:
$ perf stat -aA -e cycles,instructions sleep 1
Performance counter stats for 'system wide':
CPU0 116,057,380 cycles
CPU1 86,084,722 cycles
CPU2 99,423,125 cycles
CPU3 98,272,994 cycles
CPU0 53,369,217 instructions # 0.46 insn per cycle
CPU1 33,378,058 instructions # 0.29 insn per cycle
CPU2 58,150,086 instructions # 0.50 insn per cycle
CPU3 40,029,703 instructions # 0.34 insn per cycle
1.001816971 seconds time elapsed
So the IPC for CPU1 should be 0.38 (= 33,378,058 / 86,084,722)
but it was 0.29 (= 33,378,058 / 116,057,380) and so on.
After:
$ perf stat -aA -e cycles,instructions sleep 1
Performance counter stats for 'system wide':
CPU0 109,621,384 cycles
CPU1 159,026,454 cycles
CPU2 99,460,366 cycles
CPU3 124,144,142 cycles
CPU0 44,396,706 instructions # 0.41 insn per cycle
CPU1 120,195,425 instructions # 0.76 insn per cycle
CPU2 44,763,978 instructions # 0.45 insn per cycle

x86/mce: Do not overwrite no_way_out if mce_end() fails
Currently, if mce_end() fails, no_way_out - the variable denoting whether the machine can recover from this MCE - is determined by whether the worst severity that was found across the MCA banks associated with the current CPU, is of panic severity. However, at this point no_way_out could have been already set by mca_start() after looking at all severities of all CPUs that entered the MCE handler. If mce_end() fails, check first if no_way_out is already set and, if so, stick to it, otherwise use the local worst value.

KVM: x86: Fix split-irqchip vs interrupt injection window request
kvm_cpu_accept_dm_intr and kvm_vcpu_ready_for_interrupt_injection are
a hodge-podge of conditions, hacked together to get something that
more or less works. But what is actually needed is much simpler;
in both cases the fundamental question is, do we have a place to stash
an interrupt if userspace does KVM_INTERRUPT?
In userspace irqchip mode, that is !vcpu->arch.interrupt.injected.
Currently kvm_event_needs_reinjection(vcpu) covers it, but it is
unnecessarily restrictive.
In split irqchip mode it's a bit more complicated, we need to check
kvm_apic_accept_pic_intr(vcpu) (the IRQ window exit is basically an INTACK
cycle and thus requires ExtINTs not to be masked) as well as
!pending_userspace_extint(vcpu). However, there is no need to
check kvm_event_needs_reinjection(vcpu), since split irqchip keeps
pending ExtINT state separate from event injection state, and checking
kvm_cpu_has_interrupt(vcpu) is wrong too since ExtINT has higher
priority than APIC interrupts. In fact the latter fixes a bug:
when userspace requests an IRQ window vmexit, an interrupt in the
local APIC can cause kvm_cpu_has_interrupt() to be true and thus
kvm_vcpu_ready_for_interrupt_injection() to return false. When this
happens, vcpu_run does not exit to userspace but the interrupt window
vmexits keep occurring. The VM loops without any hope of making progress.
Once we try to fix these with something like
return kvm_arch_interrupt_allowed(vcpu) &&
- !kvm_cpu_has_interrupt(vcpu) &&
- !kvm_event_needs_reinjection(vcpu) &&
- kvm_cpu_accept_dm_intr(vcpu);
+ (!lapic_in_kernel(vcpu)
+ ? !vcpu->arch.interrupt.injected
+ : (kvm_apic_accept_pic_intr(vcpu)
+ && !pending_userspace_extint(v)));
we realize two things. First, thanks to the previous patch the complex
conditional can reuse !kvm_cpu_has_extint(vcpu). Second, the interrupt
window request in vcpu_enter_guest()
bool req_int_win =
dm_request_for_irq_injection(vcpu) &&
kvm_cpu_accept_dm_intr(vcpu);
should be kept in sync with kvm_vcpu_ready_for_interrupt_injection():
it is unnecessary to ask the processor for an interrupt window
if we would not be able to return to userspace. Therefore,
kvm_cpu_accept_dm_intr(vcpu) is basically !kvm_cpu_has_extint(vcpu)
ANDed with the existing check for masked ExtINT. It all makes sense:
- we can accept an interrupt from userspace if there is a place
to stash it (and, for irqchip split, ExtINTs are not masked).
Interrupts from userspace _can_ be accepted even if right now
EFLAGS.IF=0.
- in order to tell userspace we will inject its interrupt ("IRQ
window open" i.e. kvm_vcpu_ready_for_interrupt_injection), both
KVM and the vCPU need to be ready to accept the interrupt.
... and this is what the patch implements.

KVM: x86: handle !lapic_in_kernel case in kvm_cpu_*_extint
Centralize handling of interrupts from the userspace APIC
in kvm_cpu_has_extint and kvm_cpu_get_extint, since
userspace APIC interrupts are handled more or less the
same as ExtINTs are with split irqchip. This removes
duplicated code from kvm_cpu_has_injectable_intr and
kvm_cpu_has_interrupt, and makes the code more similar
between kvm_cpu_has_{extint,interrupt} on one side
and kvm_cpu_get_{extint,interrupt} on the other.

netfilter: nftables_offload: build mask based from the matching bytes
Userspace might match on prefix bytes of header fields if they are on
the byte boundary, this requires that the mask is adjusted accordingly.
Use NFT_OFFLOAD_MATCH_EXACT() for meta since prefix byte matching is not
allowed for this type of selector.
The bitwise expression might be optimized out by userspace, hence the
kernel needs to infer the prefix from the number of payload bytes to
match on. This patch adds nft_payload_offload_mask() to calculate the
bitmask to match on the prefix.

netfilter: nftables_offload: set address type in control dissector
This patch adds nft_flow_rule_set_addr_type() to set the address type
from the nft_payload expression accordingly.
If the address type is not set in the control dissector then a rule that
matches either on source or destination IP address does not work.
After this patch, nft hardware offload generates the flow dissector
configuration as tc-flower does to match on an IP address.
This patch has been also tested functionally to make sure packets are
filtered out by the NIC.
This is also getting the code aligned with the existing netfilter flow
offload infrastructure which is also setting the control dissector.

can: af_can: can_rx_unregister(): remove WARN() statement from list operation sanity check
To detect potential bugs in CAN protocol implementations (double removal of receiver entries) a WARN() statement has been used if no matching list item was found for removal. The fault injection issued by syzkaller was able to create a situation where the closing of a socket runs simultaneously to the notifier call chain for removing the CAN network device in use. This case is very unlikely in real life but it doesn't break anything. Therefore we just replace the WARN() statement with pr_warn() to preserve the notification for the CAN protocol development.

can: m_can: fix nominal bitiming tseg2 min for version >= 3.1
At lest the revision 3.3.0 of the bosch m_can IP core specifies that valid
register values for "Nominal Time segment after sample point (NTSEG2)" are from
1 to 127. As the hardware uses a value of one more than the programmed value,
mean tseg2_min is 2.
This patch fixes the tseg2_min value accordingly.

can: m_can: m_can_open(): remove IRQF_TRIGGER_FALLING from request_threaded_irq()'s flags
The threaded IRQ handler is used for the tcan4x5x driver only. The IRQ pin of
the tcan4x5x controller is active low, so better not use IRQF_TRIGGER_FALLING
when requesting the IRQ. As this can result in missing interrupts.
Further, if the device tree specified the interrupt as "IRQ_TYPE_LEVEL_LOW",
unloading and reloading of the driver results in the following error during
ifup:
| irq: type mismatch, failed to map hwirq-31 for gpio@20a8000!
| tcan4x5x spi1.1: m_can device registered (irq=0, version=32)
| tcan4x5x spi1.1 can2: TCAN4X5X successfully initialized.
| tcan4x5x spi1.1 can2: failed to request interrupt
This patch fixes the problem by removing the IRQF_TRIGGER_FALLING from the
request_threaded_irq().

batman-adv: Don't always reallocate the fragmentation skb head
When a packet is fragmented by batman-adv, the original batman-adv header
is not modified. Only a new fragmentation is inserted between the original
one and the ethernet header. The code must therefore make sure that it has
a writable region of this size in the skbuff head.
But it is not useful to always reallocate the skbuff by this size even when
there would be more than enough headroom still in the skb. The reallocation
is just to costly during in this codepath.
