Driver should not be scheduling any more completion handlers

during the QP destroy, driver may still schedule completion
handlers. This can cause a race where the destroy_cq and poll_cq

Commit eda0047296a1 ("mm: make the page fault mmap locking killable")
intentionally made it much easier to trigger the "page fault fails
because a fatal signal is pending" situation, by having the mmap locking
fail early in that case.
We have long aborted page faults in other fatal cases when the actual IO
for a page is interrupted by SIGKILL - which is particularly useful for
the traditional case of NFS hanging due to network issues, but local
filesystems could cause it too if you happened to get the SIGKILL while
waiting for a page to be faulted in (eg lock_folio_maybe_drop_mmap()).
So aborting the page fault wasn't a new condition - but it now triggers
earlier, before we even get to 'handle_mm_fault()'. And as a result the
error doesn't go through our 'fault_signal_pending()' logic, and doesn't
get filtered away there.
Normally you'd never even notice, because if a fatal signal is pending,
the new SIGSEGV we send ends up being ignored anyway.
But it turns out that there is one very noticeable exception: if you
enable 'show_unhandled_signals', the aborted page fault will be logged
in the kernel messages, and you'll get a scary line looking something
like this in your logs:
pverados[2183248]: segfault at 55e5a00f9ae0 ip 000055e5a00f9ae0 sp 00007ffc0720bea8 error 14 in perl[55e5a00d4000+195000] likely on CPU 10 (core 4, socket 0)
which is rather misleading. It's not really a segfault at all, it's
just "the thread was killed before the page fault completed, so we
aborted the page fault".
Fix this by just making it clear that a pending fatal signal means that
any new signal coming in after that is implicitly handled. This will
avoid the misleading logging, since now the signal isn't 'unhandled' any
more.

Commit c4e34dd99f2e ("x86: simplify load_unaligned_zeropad()

handled. The kernel now uses the fault_address in fixup_exception() to
verify the address calculations for the load_unaligned_zeropad().
It works fine for #PF, but breaks on #VE since no fault address is
passed down to fixup_exception().
Propagating ve_info.gla down to fixup_exception() resolves the issue.

Only the HW rfkill state is toggled on laptops with quirks->ec_read_only
(so far only MSI Wind U90/U100). There are, however, a few issues with
the implementation:
1. The initial HW state is always unblocked, regardless of the actual
state on boot, because msi_init_rfkill only sets the SW state,
regardless of ec_read_only.
2. The initial SW state corresponds to the actual state on boot, but it
can't be changed afterwards, because set_device_state returns
-EOPNOTSUPP. It confuses the userspace, making Wi-Fi and/or Bluetooth
unusable if it was blocked on boot, and breaking the airplane mode if
the rfkill was unblocked on boot.
Address the above issues by properly initializing the HW state on
ec_read_only laptops and by allowing the userspace to toggle the SW
state. Don't set the SW state ourselves and let the userspace fully
control it. Toggling the SW state is a no-op, however, it allows the
userspace to properly toggle the airplane mode. The actual SW radio
disablement is handled by the corresponding rtl818x_pci and btusb
drivers that have their own rfkills.

[ Upstream commit fa532bee17d15acf8bba4bc8e2062b7a093ba801 ]
When adding a point to point downlink to team device, we neglected to reset
the team's flags, which were still using flags like BROADCAST and
MULTICAST. Consequently, this would initiate ARP/DAD for P2P downlink
interfaces, such as when adding a GRE device to team device. Fix this by
remove multicast/broadcast flags and add p2p and noarp flags.
After removing the none ethernet interface and adding an ethernet interface
to team, we need to reset team interface flags. Unlike bonding interface,
team do not need restore IFF_MASTER, IFF_SLAVE flags.

[ Upstream commit d11b0df7ddf1831f3e170972f43186dad520bfcc ]
For both IPv4 and IPv6 incoming TCP connections are tracked in a hash
table with a hash over the source & destination addresses and ports.
However, the IPv6 hash is insufficient and can lead to a high rate of
collisions.
The IPv6 hash used an XOR to fit everything into the 96 bits for the
fast jenkins hash, meaning it is possible for an external entity to
ensure the hash collides, thus falling back to a linear search in the
bucket, which is slow.
We take the approach of hash the full length of IPv6 address in
__ipv6_addr_jhash() so that all users can benefit from a more secure
version.
While this may look like it adds overhead, the reality of modern CPUs
means that this is unmeasurable in real world scenarios.
In simulating with llvm-mca, the increase in cycles for the hashing
code was ~16 cycles on Skylake (from a base of ~155), and an extra ~9
on Nehalem (base of ~173).
In commit dd6d2910c5e0 ("netfilter: conntrack: switch to siphash")
netfilter switched from a jenkins hash to a siphash, but even the faster
hsiphash is a more significant overhead (~20-30%) in some preliminary
testing. So, in this patch, we keep to the more conservative approach to
ensure we don't add much overhead per SYN.
In testing, this results in a consistently even spread across the
connection buckets. In both testing and real-world scenarios, we have
not found any measurable performance impact.

VXLAN-GPE does not add an extra inner Ethernet header. Take that into
account when calculating header length.
This causes problems in skb_tunnel_check_pmtu, where incorrect PMTU is
cached.
In the collect_md mode (which is the only mode that VXLAN-GPE
supports), there's no magic auto-setting of the tunnel interface MTU.
It can't be, since the destination and thus the underlying interface
may be different for each packet.
So, the administrator is responsible for setting the correct tunnel
interface MTU. Apparently, the administrators are capable enough to
calculate that the maximum MTU for VXLAN-GPE is (their_lower_MTU - 36).
They set the tunnel interface MTU to 1464. If you run a TCP stream over
such interface, it's then segmented according to the MTU 1464, i.e.
producing 1514 bytes frames. Which is okay, this still fits the lower
MTU.
However, skb_tunnel_check_pmtu (called from vxlan_xmit_one) uses 50 as
the header size and thus incorrectly calculates the frame size to be
1528. This leads to ICMP too big message being generated (locally),
PMTU of 1450 to be cached and the TCP stream to be resegmented.
The fix is to use the correct actual header size, especially for
skb_tunnel_check_pmtu calculation.

In iavf_adminq_task(), if the function can't acquire the
adapter->crit_lock, it checks if the driver is removing. If so, it simply
exits without re-enabling the interrupt. This is done to ensure that the
task stops processing as soon as possible once the driver is being removed.
However, if the IAVF_FLAG_PF_COMMS_FAILED is set, the function checks this
before attempting to acquire the lock. In this case, the function exits
early and re-enables the interrupt. This will happen even if the driver is
already removing.
Avoid this, by moving the check to after the adapter->crit_lock is
acquired. This way, if the driver is removing, we will not re-enable the
interrupt.
