[ Upstream commit 0527b19fa4f390a6054612e1fa1dd4f8efc96739 ]
Tests on device show the JD2 mode does not work at all, the 'Headphone
Jack' and 'Headset Mic Jack' are shown as 'on' always.
JD1 seems to be the better option, with at least a change between the
two cases.
Jack not plugged-in:
[root@fedora ~]# amixer -Dhw:0 cget numid=12
numid=12,iface=CARD,name='Headphone Jack'
; type=BOOLEAN,access=r-------,values=1
: values=off
[root@fedora ~]# amixer -Dhw:0 cget numid=13
numid=13,iface=CARD,name='Headset Mic Jack'
; type=BOOLEAN,access=r-------,values=1
: values=off
Jack plugged-in:
[root@fedora ~]# amixer -Dhw:0 cget numid=13
numid=13,iface=CARD,name='Headset Mic Jack'
; type=BOOLEAN,access=r-------,values=1
: values=on
[root@fedora ~]# amixer -Dhw:0 cget numid=13
numid=13,iface=CARD,name='Headset Mic Jack'
; type=BOOLEAN,access=r-------,values=1
: values=on
The 'Headset Mic Jack' is updated with a delay which seems normal with
additional calibration needed.

[ Upstream commit 173b6e383d2a204c9921ffc1eca3b87aa2106c33 ]
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 d668769eb9c52b150753f1653f7f5a0aeb8239d2 ]
Syzbot reported uninit value in mcs7830_bind(). The problem was in
missing validation check for bytes read via usbnet_read_cmd().
usbnet_read_cmd() internally calls usb_control_msg(), that returns
number of bytes read. Code should validate that requested number of bytes
was actually read.
So, this patch adds missing size validation check inside
mcs7830_get_reg() to prevent uninit value bugs

[ Upstream commit bce9a0b7900836df223ab638090df0cb8430d9e8 ]
Some older devices cannot accommodate the 40 seconds timeout
cap for long running commands (such as NVRAM commands) due to
hardware limitations. Allow these devices to request more time for
these long running commands, but print a warning, since the longer
timeout may cause the hung task watchdog to trigger. In the case of a
firmware update operation, this is preferable to failing outright.
v2: Use bp->hwrm_cmd_max_timeout directly without the constants.

[ Upstream commit 6f022c2ddbcefaee79502ce5386dfe351d457070 ]
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.

For the possible failure of the platform_get_irq(), the returned irq
could be error number and will finally cause the failure of the

Consider that platform_get_irq() can now in certain cases return

effectively convert that into -EINVAL, even at probe time rather than
later on. So it might be better to check just now.

[ Upstream commit a14e6b69f393d651913edcbe4ec0dec27b8b4b40 ]
Assuming the test setup described here:
https://patchwork.kernel.org/project/netdevbpf/cover/20210205130240.4072854-1-vladimir.oltean@nxp.com/
(swp1 and swp2 are in bond0, and bond0 is in a bridge with swp0)
it can be seen that when swp1 goes down (on either board A or B), then
traffic that should go through that port isn't forwarded anywhere.
A dump of the PGID table shows the following:
PGID_DST[0] = ports 0
PGID_DST[1] = ports 1
PGID_DST[2] = ports 2
PGID_DST[3] = ports 3

Whereas a "good" PGID configuration for that setup should have looked
like this:
PGID_DST[0] = ports 0

PGID_AGGR[4] = ports 0, 2, 3, 4, 5

PGID_SRC[5] = no ports
PGID_SRC[6] = ports 0, 1, 2, 3, 4, 5
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.

[ Upstream commit 530792efa6cb86f5612ff093333fec735793b582 ]
Since commit cffa4b2122f5 ("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."

[ Upstream commit dc35616e6c2907b0c0c391a205802d8880f7fd85 ]
This needs to copy an unsigned int from user space instead of a long to
avoid breaking user space with an API change.
I have updated all the integer overflow checks from ULONG to UINT as
well. This is a slight API change but I do not expect it to affect
anything in real life.

+---------+---------+---------+---------+----------+
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,

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.
