The following warning from the refcount framework is seen during ghes
initialization:
EDAC MC0: Giving out device to module ghes_edac.c controller ghes_edac: DEV ghes (INTERRUPT)
------------[ cut here ]------------
refcount_t: increment on 0; use-after-free.
WARNING: CPU: 36 PID: 1 at lib/refcount.c:156 refcount_inc_checked
[...]
Call trace:
refcount_inc_checked
ghes_edac_register
ghes_probe
...
It warns if the refcount is incremented from zero. This warning is
reasonable as a kernel object is typically created with a refcount of
one and freed once the refcount is zero. Afterwards the object would be
"used-after-free".
For GHES, the refcount is initialized with zero, and that is why this
message is seen when initializing the first instance. However, whenever
the refcount is zero, the device will be allocated and registered. Since
the ghes_reg_mutex protects the refcount and serializes allocation and
freeing of ghes devices, a use-after-free cannot happen here.
Instead of using refcount_inc() for the first instance, use
refcount_set(). This can be used here because the refcount is zero at
this point and can not change due to its protection by the mutex.

If negotiated NVSP version <= NVSP_PROTOCOL_VERSION_6, the offset may
be wrong (too small) due to a host bug. This can cause missing the
end of the send indirection table, and add multiple zero entries from
leading zeros before the data region. This bug adds extra burden on
channel 0.
So fix the offset by computing it from the data structure sizes. This
will ensure netvsc driver runs normally on unfixed hosts, and future
fixed hosts.

To reach the data region, the existing code adds offset in struct
nvsp_5_send_indirect_table on the beginning of this struct. But the
offset should be based on the beginning of its container,
struct nvsp_message. This bug causes the first table entry missing,
and adds an extra zero from the zero pad after the data region.
This can put extra burden on the channel 0.
So, correct the offset usage. Also add a boundary check to ensure
not reading beyond data region.

net: introduce and use route hint
This series leverages the listification infrastructure to avoid
unnecessary route lookup on ingress packets. In absence of custom rules,
packets with equal daddr will usually land on the same dst.
When processing packet bursts (lists) we can easily reference the previous
dst entry. When we hit the 'same destination' condition we can avoid the
route lookup, coping the already available dst.
Detailed performance numbers are available in the individual commit
messages.

This is alike the previous change, with some additional ipv4 specific
quirk. Even when using the route hint we still have to do perform
additional per packet checks about source address validity: a new
helper is added to wrap them.
Hints are explicitly disabled if the destination is a local broadcast,
that keeps the code simple and local broadcast are a slower path anyway.
UDP flood performances vs recvmmsg() receiver:

In the worst case scenario - each packet has a different
destination address - the performance delta is within noise
range.

When doing RX batch packet processing, we currently always repeat
the route lookup for each ingress packet. When no custom rules are
in place, and there aren't routes depending on source addresses,
we know that packets with the same destination address will use
the same dst.
This change tries to avoid per packet route lookup caching
the destination address of the latest successful lookup, and
reusing it for the next packet when the above conditions are
in place. Ingress traffic for most servers should fit.
The measured performance delta under UDP flood vs a recvmmsg
receiver is as follow:

On TX path, timestamping works on packet which requires timestamp.
The injection header will be configured accordingly, and skb clone
requires timestamp will be added into a list. The TX timestamp
is final handled in threaded interrupt handler when PTP timestamp
FIFO is ready.
On RX path, timestamping is always working. The RX timestamp could
be got from extraction header.

Pull arm64 fix from Will Deacon:
"Ensure PAN is re-enabled following user fault in uaccess routines.
After I thought we were done for 5.4, we had a report this week of a
nasty issue that has been shown to leak data between different user
address spaces thanks to corruption of entries in the TLB. In
hindsight, we should have spotted this in review when the PAN code was
merged back in v4.3, but hindsight is 20/20 and I'm trying not to beat
myself up too much about it despite being fairly miserable.
Anyway, the fix is "obvious" but the actual failure is more more
subtle, and is described in the commit message. I've included a fairly
mechanical follow-up patch here as well, which moves this checking out
into the C wrappers which is what we do for {get,put}_user() already
and allows us to remove these bloody assembly macros entirely. The
patches have passed kernelci [1] [2] [3] and CKI [4] tests over night,
as well as some targetted testing [5] for this particular issue.
The first patch is tagged for stable and should be applied to 4.14,
4.19 and 5.3. I have separate backports for 4.4 and 4.9, which I'll
send out once this has landed in your tree (although the original

- do the validation when dst is not yet allocated as Jakub suggested.
- use Duplicate instead of Wrong in err msg for extack.

This patch is to allow setting vxlan options using the
act_tunnel_key action. Different from geneve options,
only one option can be set. And also, geneve options
and vxlan options can't be set at the same time.
gbp is the only param for vxlan options:
# ip link add name vxlan0 type vxlan dstport 0 external
# tc qdisc add dev eth0 ingress
# tc filter add dev eth0 protocol ip parent ffff: \
flower indev eth0 \
ip_proto udp \
action tunnel_key \
set src_ip 10.0.99.192 \
dst_ip 10.0.99.193 \
dst_port 6081 \
id 11 \
vxlan_opts 01020304 \
action mirred egress redirect dev vxlan0
v1->v2:
- add .strict_start_type for enc_opts_policy as Jakub noticed.
- use Duplicate instead of Wrong in err msg for extack as Jakub
suggested.

If rvu_get_blkaddr() fails, then this rvu_cgx_nix_cuml_stats() returns
zero and we write some uninitialized data into the debugfs output.
On the error paths, the use of the uninitialized "*stat" is harmless,
but it will lead to a Smatch warning (static analysis) and a UBSan
warning (runtime analysis) so we should prevent that as well.

If transport->init() fails, we can't assign the transport to the
socket, because it's not initialized correctly, and any future
calls to the transport callbacks would have an unexpected behavior.

In nbd_add_socket when krealloc succeeds, if nsock's allocation fail the
reallocted memory is leak. The correct behaviour should be assigning the
reallocted memory to config->socks right after success.
