Many of the synchronization points are sometimes called under the rtnl
lock, which means we should use synchronize_net rather than
synchronize_rcu. Under the hood, this expands to using the expedited
flavor of function in the event that rtnl is held, in order to not stall
other concurrent changes.
This fixes some very, very long delays when removing multiple peers at
once, which would cause some operations to take several minutes.

Apparently, various versions of gcc have O3-related miscompiles. Looking
at the difference between -O2 and -O3 for gcc 11 doesn't indicate
miscompiles, but the difference also doesn't seem so significant for
performance that it's worth risking.

If the hardware is still accessing memory after SMMU translation
is disabled (as part of smmu shutdown callback), then the
IOVAs (I/O virtual address) which it was using will go on the bus
as the physical addresses which will result in unknown crashes
like NoC/interconnect errors.
So, implement shutdown callback for i2c driver to suspend the bus
during system "reboot" or "shutdown".

The first two bits of the CPUID leaf 0x8000001F EAX indicate whether SEV
or SME is supported, respectively. It's better to check whether SEV or
SME is actually supported before accessing the MSR_AMD64_SEV to check
whether SEV or SME is enabled.
This is both a bare-metal issue and a guest/VM issue. Since the first
generation Hygon Dhyana CPU doesn't support the MSR_AMD64_SEV, reading that
MSR results in a #GP - either directly from hardware in the bare-metal
case or via the hypervisor (because the RDMSR is actually intercepted)
in the guest/VM case, resulting in a failed boot. And since this is very
early in the boot phase, rdmsrl_safe()/native_read_msr_safe() can't be
used.
So check the CPUID bits first, before accessing the MSR.

Currently in the ice driver, the check whether to
allow a LLDP packet to egress the interface from the
PF_VSI is being based on the SKB's priority field.
It checks to see if the packets priority is equal to
TC_PRIO_CONTROL. Injected LLDP packets do not always
meet this condition.
SCAPY defaults to a sk_buff->protocol value of ETH_P_ALL
(0x0003) and does not set the priority field. There will
be other injection methods (even ones used by end users)
that will not correctly configure the socket so that
SKB fields are correctly populated.
Then ethernet header has to have to correct value for
the protocol though.
Add a check to also allow packets whose ethhdr->h_proto
matches ETH_P_LLDP (0x88CC).

Commit 12bb018c538c ("ice: Refactor VF reset") caused a regression
that removes the ability for a VF to request a different amount of
queues via VIRTCHNL_OP_REQUEST_QUEUES. This prevents VF drivers to
either increase or decrease the number of queue pairs they are
allocated. Fix this by using the variable vf->num_req_qs when
determining the vf->num_vf_qs during VF VSI creation.

__bad_area_nosemaphore() calls both force_sig_pkuerr() and
force_sig_fault() when handling SEGV_PKUERR. This does not cause
problems because the second signal is filtered by the legacy_queue()
check in __send_signal() because in both cases, the signal is SIGSEGV,
the second one seeing that the first one is already pending.
This causes the kernel to do unnecessary work so send the signal only
once for SEGV_PKUERR.

drm/tegra: Fixes for v5.13-rc5
The most important change here fixes a race condition that causes either
HDA or (more frequently) display to malfunction because they race for
enabling the SOR power domain at probe time.
Other than that, there's a couple of build warnings for issues
introduced in v5.13 as well as some minor fixes, such as reference leak

==================================================================
In the ip6_route_info_create function, in the case that the nh pointer
is not NULL, the fib6_nh in fib6_info has not been allocated.
Therefore, when trying to free fib6_info in this error case using
fib6_info_release, the function will call fib6_info_destroy_rcu,
which it will access fib6_nh_release(f6i->fib6_nh);
However, f6i->fib6_nh doesn't have any refcount yet given the lack of allocation
causing the reported memory issue above.
Therefore, releasing the empty pointer directly instead would be the solution.

commit db43b30cd89c ("cxgb4: add ethtool n-tuple filter deletion")
has moved searching for next highest priority HASH filter rule to
cxgb4_flow_rule_destroy(), which searches the rhashtable before the
the rule is removed from it and hence always finds at least 1 entry.
Fix by removing the rule from rhashtable first before calling
cxgb4_flow_rule_destroy() and hence avoid fetching stale info.

Pavel Skripkin says:
====================
This patch series fix 2 memory leaks in caif
interface.
Syzbot reported memory leak in cfserl_create().
The problem was in cfcnfg_add_phy_layer() function.
This function accepts struct cflayer *link_support and
assign it to corresponting structures, but it can fail
in some cases.
These cases must be handled to prevent leaking allocated
struct cflayer *link_support pointer, because if error accured
before assigning link_support pointer to somewhere, this pointer
must be freed.
Fail log:
[ 49.051872][ T7010] caif:cfcnfg_add_phy_layer(): Too many CAIF Link Layers (max 6)
[ 49.110236][ T7042] caif:cfcnfg_add_phy_layer(): Too many CAIF Link Layers (max 6)
[ 49.134936][ T7045] caif:cfcnfg_add_phy_layer(): Too many CAIF Link Layers (max 6)
[ 49.163083][ T7043] caif:cfcnfg_add_phy_layer(): Too many CAIF Link Layers (max 6)
[ 55.248950][ T6994] kmemleak: 4 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
int cfcnfg_add_phy_layer(..., struct cflayer *link_support, ...)
{
...
/* CAIF protocol allow maximum 6 link-layers */
for (i = 0; i < 7; i++) {
phyid = (dev->ifindex + i) & 0x7;
if (phyid == 0)
continue;
if (cfcnfg_get_phyinfo_rcu(cnfg, phyid) == NULL)
goto got_phyid;
}
pr_warn("Too many CAIF Link Layers (max 6)\n");
goto out;
...
if (link_support != NULL) {
link_support->id = phyid;
layer_set_dn(frml, link_support);
layer_set_up(link_support, frml);
layer_set_dn(link_support, phy_layer);
layer_set_up(phy_layer, link_support);
}
...
}
As you can see, if cfcnfg_add_phy_layer fails before layer_set_*,
link_support becomes leaked.
So, in this series, I made cfcnfg_add_phy_layer()
return an int and added error handling code to prevent
leaking link_support pointer in caif_device_notify()
and cfusbl_device_notify() functions.

====================
This series contains updates to igb, igc, ixgbe, ixgbevf, i40e and ice
drivers.
Kurt Kanzenbach fixes XDP for igb when PTP is enabled by pulling the

Magnus adds missing exception tracing for XDP on igb, igc, ixgbe,
ixgbevf, i40e and ice drivers.
Maciej adds tracking of AF_XDP zero copy enabled queues to resolve an
issue with copy mode Tx for the ice driver.
Note: Patch 7 will conflict when merged with net-next. Please carry
these changes forward. IGC_XDP_TX and IGC_XDP_REDIRECT will need to be
changed to return to conform with the net-next changes. Let me know if
you have issues.

Syzbot reported memory leak in kcm_sendmsg()[1].
The problem was in non-freed frag_list in case of error.
In the while loop:
if (head == skb)
skb_shinfo(head)->frag_list = tskb;
else
skb->next = tskb;
frag_list filled with skbs, but nothing was freeing them.

Some firmware when operation don't may have broken versions leading to
error like the following:
[ 6.176482] Bluetooth: hci0: Firmware revision 0.0 build 121 week 7 2021
[ 6.177906] bluetooth hci0: Direct firmware load for intel/ibt-20-0-0.sfi failed with error -2
[ 6.177910] Bluetooth: hci0: Failed to load Intel firmware file intel/ibt-20-0-0.sfi (-2)
Since we load the firmware file just to check if its version had changed
comparing to the one already loaded we can just skip since the firmware
is already operation.

It turned out that the VIRTIO_ID_* are not assigned in the virtio_ids.h
file in the upstream kernel. Picking the next free one was wrong and
there is a process that has been followed now.
See https://github.com/oasis-tcs/virtio-spec/issues/108 for details.

The error code is missing in this code scenario, add the error code
'-EINVAL' to the return value 'err'.
Eliminate the follow smatch warning:

'err'.
