A user reported FITRIM ioctl failing for him on ext4 on some devices
without apparent reason. After some debugging we've found out that
these devices (being LVM volumes) report rather large discard
granularity of 42MB and the filesystem had 1k blocksize and thus group
size of 8MB. Because ext4 FITRIM implementation puts discard
granularity into minlen, ext4_trim_fs() declared the trim request as
invalid. However just silently doing nothing seems to be a more
appropriate reaction to such combination of parameters since user did
not specify anything wrong.

[ Upstream commit 6f022c2ddb ]
Netfilter conntrack maintains NAT flags per connection indicating
whether NAT was configured for the connection. Openvswitch maintains
NAT flags on the per packet flow key ct_state field, indicating
whether NAT was actually executed on the packet.
When a packet misses from tc to ovs the conntrack NAT flags are set.
However, NAT was not necessarily executed on the packet because the
connection's state might still be in NEW state. As such, openvswitch
wrongly assumes that NAT was executed and sets an incorrect flow key
NAT flags.
Fix this, by flagging to openvswitch which NAT was actually done in
act_ct via tc_skb_ext and tc_skb_cb to the openvswitch module, so
the packet flow key NAT flags will be correctly set.

(swp1 and swp2 are in bond0, and bond0 is in a bridge with swp0)

In other words, in the "bad" configuration, the attempt is to remove the
inactive swp1 from the destination ports via PGID_DST. But when a MAC
table entry is learned, it is learned towards PGID_DST 1, because that
is the logical port id of the LAG itself (it is equal to the lowest
numbered member port). So when swp1 becomes inactive, if we set
PGID_DST[1] to contain just swp1 and not swp2, the packet will not have
any chance to reach the destination via swp2.
The "correct" way to remove swp1 as a destination is via PGID_AGGR
(remove swp1 from the aggregation port groups for all aggregation
codes). This means that PGID_DST[1] and PGID_DST[2] must still contain
both swp1 and swp2. This makes the MAC table still treat packets
destined towards the single-port LAG as "multicast", and the inactive
ports are removed via the aggregation code tables.
The change presented here is a design one: the ocelot_get_bond_mask()
function used to take an "only_active_ports" argument. We don't need
that. The only call site that specifies only_active_ports=true,
ocelot_set_aggr_pgids(), must retrieve the entire bonding mask, because
it must program that into PGID_DST. Additionally, it must also clear the
inactive ports from the bond mask here, which it can't do if bond_mask
just contains the active ports:
ac = ocelot_read_rix(ocelot, ANA_PGID_PGID, i);
ac &= ~bond_mask; <---- here
/* Don't do division by zero if there was no active
* port. Just make all aggregation codes zero.
*/
if (num_active_ports)
ac |= BIT(aggr_idx[i % num_active_ports]);
ocelot_write_rix(ocelot, ac, ANA_PGID_PGID, i);
So it becomes the responsibility of ocelot_set_aggr_pgids() to take
ocelot_port->lag_tx_active into consideration when populating the
aggr_idx array.

Since commit cffa4b2122 ("regmap: debugfs: Fix a memory leak when
calling regmap_attach_dev"), the following debugfs error is seen
on i.MX boards:
debugfs: Directory 'dummy-iomuxc-gpr@20e0000' with parent 'regmap' already present!
In the attempt to fix the memory leak, the above commit added a NULL check
for map->debugfs_name. For the first debufs entry, map->debugfs_name is NULL
and then the new name is allocated via kasprintf().
For the second debugfs entry, map->debugfs_name() is no longer NULL, so
it will keep using the old entry name and the duplicate name error is seen.
Quoting Mark Brown:
"That means that if the device gets freed we'll end up with the old debugfs
file hanging around pointing at nothing.
...
To be more explicit this means we need a call to regmap_debugfs_exit()
which will clean up all the existing debugfs stuff before we loose
references to it."
Call regmap_debugfs_exit() prior to regmap_debugfs_init() to fix
the problem.
Tested on i.MX6Q and i.MX6SX boards.

[ Upstream commit 04fac2cae9 ]
When these two options had to be sent -- which is not common -- the DSS
size was not being taken into account in the remaining size.
Additionally in this situation, the reported size was only the one of
the MP_FAIL which can cause issue if at the end, we need to write more
in the TCP options than previously said.
Here we use a dedicated variable for MP_FAIL size to keep the
WARN_ON_ONCE() just after.

[ Upstream commit f7d6a237d7 ]
Since full-mesh endpoint support, the reception of a single ADD_ADDR
option can cause multiple subflows creation. When such option is
accepted we increment 'add_addr_accepted' by one. When we received
a paired RM_ADDR option, we deleted all the relevant subflows,
decrementing 'add_addr_accepted' by one for each of them.
We have a similar issue for 'local_addr_used'
Fix them moving the pm endpoint accounting outside the subflow
traversal.

Currently during NIC profile disablement all VXLAN udp ports offloaded to the
HW are flushed and during its enablement the driver send notification to
the stack to inform the core that the entire UDP tunnel port state has been
lost, uplink representor doesn't have the same behavior which can cause
VXLAN udp ports offload to be in bad state while moving between modes while
VXLAN interface exist.
Fixed by aligning the uplink representor profile behavior to the NIC behavior.

Tunnel device follows RFC 6040, and during decapsulation inner
ip_ecn might change depending on inner and outer ip_ecn as follows:
+---------+----------------------------------------+
|Arriving | Arriving Outer Header |
| Inner +---------+---------+---------+----------+
| Header | Not-ECT | ECT(0) | ECT(1) | CE |
+---------+---------+---------+---------+----------+

| CE | CE | CE | CE | CE |
+---------+---------+---------+---------+----------+
Cells marked above are changed from original inner packet ip_ecn value.
Tc then matches on the modified inner ip_ecn, but hw offload which
matches the inner ip_ecn value before decap, will fail.
Fix that by mapping all the cases of outer and inner ip_ecn matching,
and only supporting cases where we know inner wouldn't be changed by
decap, or in the outer ip_ecn=CE case, inner ip_ecn didn't matter.

Routes with nexthop objects is currently not supported by multipath offload
and any attempts to use it is blocked, however this also block adding SW

Resolve this by returning NOTIFY_DONE instead of an error which will allow such

This fix also solve an issue which block adding such routes on different devices
due to missing check if the route FIB device is one of multipath devices.

Driver initiates DMA sync, hence it may skip CPU sync. Add
DMA_ATTR_SKIP_CPU_SYNC as input attribute both to dma_map_page and
dma_unmap_page to avoid redundant sync with the CPU.
When forcing the device to work with SWIOTLB, the extra sync might cause
data corruption. The driver unmaps the whole page while the hardware
used just a part of the bounce buffer. So syncing overrides the entire
page with bounce buffer that only partially contains real data.

DWC2 may be paired with a full-speed PHY which is not capable of
high-speed operation. Report this correctly to the gadget core by
setting max_speed from the core parameters.
Prior to commit 5324bad66f ("usb: dwc2: gadget: implement
udc_set_speed()") this didn't cause the hardware to be configured
incorrectly, although the speed may have been reported incorrectly. But
after that commit params.speed is updated based on a value passed in by
the gadget core which may set it to a faster speed than is supported by
the hardware. Initialising the max_speed parameter ensures the speed
passed to dwc2_gadget_set_speed() will be one supported by the hardware.
