In the case of IPIP and SIT tunnel frames the outer transport header
offset is actually set to the same offset as the inner transport header.
This results in the lco_csum call not doing any checksum computation over
the inner IPv4/v6 header data.
In order to account for that I am updating the code so that we determine
the location to start the checksum ourselves based on the location of the
IPv4 header and the length.

Pull input fixes from Dmitry Torokhov: "We are disabling automatic

and the hardware is not terribly popular and having the protocol

We also change keycode for KEY_DATA to avoid clashing with

that is still in staging, so it is extremely unlikely that someone has

This adds support for PEAK-System PCAN-USB X6 USB to CAN interface.
The CAN FD adapter PCAN-USB X6 allows the connection of up to 6 CAN FD
or CAN networks to a computer via USB. The interface is installed in an
aluminum profile casing and is shipped in versions with D-Sub connectors
or M12 circular connectors.
The PCAN-USB X6 registers in the USB sub-system as if 3x PCAN-USB-Pro FD
adapters were plugged. So, this patch:
- updates the PEAK_USB entry of the corresponding Kconfig file
- defines and adds the device id. of the PCAN-USB X6 (0x0014) into the
table of supported device ids
- defines and adds the new software structure implementing the PCAN-USB X6,
which is obviously a clone of the software structure implementing the
PCAN-USB Pro FD.

This fixes the bitimings fields ranges supported by all the CAN-FD USB
interfaces of the PEAK-System CAN-FD adapters.
Very first development versions of the IP core API defined smaller TSGEx
and SJW fields for both nominal and data bittimings records than the
production versions. This patch fixes them by enlarging their sizes to
the actual values:
field: old size: fixed size:
nominal TSGEG1 6 8
nominal TSGEG2 4 7
nominal SJW 4 7
data TSGEG1 4 5
data TSGEG2 3 4
data SJW 2 4
Note that this has no other consequences than offering larger choice to
bitrate encoding.

Merge misc fixes from Andrew Morton:
"7 fixes"
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
mm: fix false-positive WARN_ON() in truncate/invalidate for hugetlb
kasan: support use-after-scope detection
kasan: update kasan_global for gcc 7
lib/debugobjects: export for use in modules
zram: fix unbalanced idr management at hot removal
thp: fix corner case of munlock() of PTE-mapped THPs
mm, thp: propagation of conditional compilation in khugepaged.c
|
|
The zram hot removal code calls idr_remove() even when zram_remove()
returns an error (typically -EBUSY). This results in a leftover at the
device release, eventually leading to a crash when the module is
reloaded.
As described in the bug report below, the following procedure would
cause an Oops with zram:
- provision three zram devices via modprobe zram num_devices=3
- configure a size for each device
+ echo "1G" > /sys/block/$zram_name/disksize
- mkfs and mount zram0 only
- attempt to hot remove all three devices
+ echo 2 > /sys/class/zram-control/hot_remove
+ echo 1 > /sys/class/zram-control/hot_remove
+ echo 0 > /sys/class/zram-control/hot_remove
- zram0 removal fails with EBUSY, as expected
- unmount zram0
- try zram0 hot remove again
+ echo 0 > /sys/class/zram-control/hot_remove
- fails with ENODEV (unexpected)
- unload zram kernel module
+ completes successfully
- zram0 device node still exists
- attempt to mount /dev/zram0
+ mount command is killed
+ following BUG is encountered
BUG: unable to handle kernel paging request at ffffffffa0002ba0

even if caller want to do zerocopy. This will cause the callback
(vhost_net_zerocopy_callback) decrease the refcount. But when we meet

to decrease it again. This is wrong and fix this by delay the

netif_set_real_num_tx/rx_queues() are required to be called with rtnl_lock

now during System resume from suspend:
cpsw_resume()
|- cpsw_ndo_open()
|- netif_set_real_num_tx/rx_queues()

Hence, fix it by surrounding cpsw_ndo_open() by rtnl_lock/unlock() calls.

Execution 'ethtool -S' on fec device that is down causes OOPS on Vybrid
board:
Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0898200
pgd = ddecc000
[e0898200] *pgd=9e406811, *pte=400d1653, *ppte=400d1453
Internal error: : 1008 [#1] SMP ARM
...
Reason of OOPS is that fec_enet_get_ethtool_stats() accesses fec
registers while IPG clock is stopped by PM.
Fix that by caching statistics in fec_enet_private. Cache is initialized
at device probe time, and updated at statistics request time if device
is up, and also just before turning device off on down path.
Additional locking is not needed, since cached statistics is accessed
either before device is registered, or under rtnl_lock().

On macb only (not gem), when a RX queue corruption was detected from
macb_rx(), the RX queue was reset: during this process the RX ring
buffer descriptor was initialized by macb_init_rx_ring() but we forgot
to also set bp->rx_tail to 0.
Indeed, when processing the received frames, bp->rx_tail provides the
macb driver with the index in the RX ring buffer of the next buffer to
process. So when the whole ring buffer is reset we must also reset
bp->rx_tail so the driver is synchronized again with the hardware.
Since macb_init_rx_ring() is called from many locations, currently from
macb_rx() and macb_init_rings(), we'd rather add the "bp->rx_tail = 0;"
line inside macb_init_rx_ring() than add the very same line after each
call of this function.
Without this fix, the rx queue is not reset properly to recover from
queue corruption and connection drop may occur.

The ATPX method does not always exist on the dGPU, it may be located at
the iGPU. The parent device of the iGPU is the root port for which
bridge_d3 is false. This accidentally enables the legacy PM method which
conflicts with port PM and prevented the dGPU from powering on.

qlogicpti uses '__u32' for dma handle while invoking kernel DMA APIs,
instead of using dma_addr_t. This hasn't caused any 'incompatible
pointer type' warning on SPARC because until now dma_addr_t is of
type u32. However, recent changes in SPARC ATU (iommu) enabled 64bit
DMA and therefore dma_addr_t became of type u64. This makes
'incompatible pointer type' warnings inevitable.
e.g.
drivers/scsi/qlogicpti.c: In function ‘qpti_map_queues’:
drivers/scsi/qlogicpti.c:813: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type
./include/linux/dma-mapping.h:445: note: expected ‘dma_addr_t *’ but argument is of type ‘__u32 *’
drivers/scsi/qlogicpti.c:822: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type
./include/linux/dma-mapping.h:445: note: expected ‘dma_addr_t *’ but argument is of type ‘__u32 *’
For the record, qlogicpti never executes on sun4v. Therefore even
though 64bit DMA is enabled on SPARC, qlogicpti continues to use
legacy iommu that guarantees DMA address is always in 32bit range.
This patch resolves aforementioned compiler warnings.

device managed flow steering
In procedure mlx4_flow_steer_promisc_add(), several fields
were left uninitialized in the rule structure.
Correctly initialize these fields.
