skb->len is used to calculate statistics after xmit invocation.
Under a stress load it may happen that skb will be xmited,
rx interrupt will come and skb will be freed, all before xmit function
is even returned.
Eventually, skb->len will access unallocated area.
Moving stats calculation into tx_clean routine.

Add checks to not enable multiple loopback modes simultaneously,
It was also discovered that for dma loopback to function correctly

Artificial HW reliability tests revealed a possible hangup in
the driver. Normally, when device disappears from bus, all
register reads returns 0xFFFFFFFF.
At remote procedure invocation towards FW there is a logic
where result is compared with -1 in a loop.
That caused an infinite loop if hardware due to some issues
disappears from bus.
Add extra result checks to prevent this.

Yet another checksum offload compatibility issue was found.
The known issue is that AQC HW marks tcp packets with 0xFFFF checksum
as invalid (1). This is workarounded in driver, passing all the suspicious
packets up to the stack for further csum validation.
Another HW problem (2) is that it hides invalid csum of LRO aggregated
packets inside of the individual descriptors. That was workarounded
by forced scan of all LRO descriptors for checksum errors.
However the scan logic was joint for both LRO and multi-descriptor
packets (jumbos). And this causes the issue.
We have to drop LRO packets with the detected bad checksum
because of (2), but we have to pass jumbo packets to stack because of (1).
When using windows tcp partner with jumbo frames but with LSO disabled
driver discards such frames as bad checksummed. But only LRO frames
should be dropped, not jumbos.
On such a configurations tcp stream have a chance of drops and stucks.

After commit 71130f29979c ("vxlan: fix tos value before xmit") we start
strict vxlan xmit tos value by RT_TOS(), which limits the tos value less
than 0x1E. With current value 0x40 the test will failed with "v1: Expected
to capture 10 packets, got 0". So let's choose a smaller tos value for
testing.

Since IFLA_ALT_IFNAME is an NLA_STRING, we have no

We should use nla_strdup() instead of kstrdup(), since this

Convert net/rds to use the newly introduces pin_user_pages() API,
which properly sets FOLL_PIN. Setting FOLL_PIN is now required for
code that requires tracking of pinned pages.
Note that this effectively changes the code's behavior: it now
ultimately calls set_page_dirty_lock(), instead of set_page_dirty().
This is probably more accurate.
As Christoph Hellwig put it, "set_page_dirty() is only safe if we are
dealing with a file backed page where we have reference on the inode it
hangs off." [1]

When splitting an RTA_MULTIPATH request into multiple routes and adding the
second and later components, we must not simply remove NLM_F_REPLACE but
instead replace it by NLM_F_CREATE. Otherwise, it may look like the netlink
message was malformed.
For example,
ip route add 2001:db8::1/128 dev dummy0
ip route change 2001:db8::1/128 nexthop via fe80::30:1 dev dummy0 \
nexthop via fe80::30:2 dev dummy0
results in the following warnings:
[ 1035.057019] IPv6: RTM_NEWROUTE with no NLM_F_CREATE or NLM_F_REPLACE
[ 1035.057517] IPv6: NLM_F_CREATE should be set when creating new route
This patch makes the nlmsg sequence look equivalent for __ip6_ins_rt() to
what it would get if the multipath route had been added in multiple netlink
operations:
ip route add 2001:db8::1/128 dev dummy0
ip route change 2001:db8::1/128 nexthop via fe80::30:1 dev dummy0
ip route append 2001:db8::1/128 nexthop via fe80::30:2 dev dummy0

After commit 27596472473a ("ipv6: fix ECMP route replacement") it is no
longer possible to replace an ECMP-able route by a non ECMP-able route.
For example,
ip route add 2001:db8::1/128 via fe80::1 dev dummy0
ip route replace 2001:db8::1/128 dev dummy0
does not work as expected.
Tweak the replacement logic so that point 3 in the log of the above commit
becomes:
3. If the new route is not ECMP-able, and no matching non-ECMP-able route
exists, replace matching ECMP-able route (if any) or add the new route.
We can now summarize the entire replace semantics to:
When doing a replace, prefer replacing a matching route of the same
"ECMP-able-ness" as the replace argument. If there is no such candidate,
fallback to the first route found.

For tc ip_proto filter, when we extract the flow via __skb_flow_dissect()
without flag FLOW_DISSECTOR_F_STOP_AT_ENCAP, we will continue extract to
the inner proto.
So for GRE + ICMP messages, we should not track GRE proto, but inner ICMP
proto.
For test mirror_gre.sh, it may make user confused if we capture ICMP
message on $h3(since the flow is GRE message). So I move the capture
dev to h3-gt{4,6}, and only capture ICMP message.

If CONFIG_QFMT_V2 is not enabled, but CONFIG_QUOTA is enabled, when a
user tries to mount a file system with the quota or project quota
enabled, the kernel will emit a very confusing messsage:
EXT4-fs warning (device vdc): ext4_enable_quotas:5914: Failed to enable quota tracking (type=0, err=-3). Please run e2fsck to fix.
EXT4-fs (vdc): mount failed
We will now report an explanatory message indicating which kernel

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.
