* dp83640: Only wait for timestamps for packets with timestamping enabled.Stefan Sørensen2015-11-031-12/+13
| | | | | | | | | In the packet timestamping function, check that the ptp version and protocol of the packet matches what we have configured the hardware to actually generate timestamps for, before looking/waiting for a timestamp.

* dp83640: Prune rx timestamp list before reading from itStefan Sørensen2015-11-031-0/+1
| | | | | | | | | | The list of rx timestamps are currently only pruned of old entries when a new entry is inserted. If no new entries are added, old timestamps may survive beyond their lifetime, possible causing them to be attached to packets with the same sequence number after a rollover.

* dp83640: Delay scheduled work.Stefan Sørensen2015-11-031-8/+12
| | | | | | | | | | Currently rx_timestamp_work reschedules itself as a regular workqueue item, effectively causing it run constantly as long as there are packets left in the queue. Fix by using delayed workqueue items, limiting it to run only every two jiffies. Signed-off-by: Stefan Sørensen <stefan.sorensen@spectralink.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* dp83640: Include hash in timestamp/packet matchingStefan Sørensen2015-11-031-3/+15
| | | | | | | | | | | Only using the message type and sequence id for matching timestamps with packets is error prone, as multiple clients may very well be sending packets with the same messagetype and timestamp at the same time. Fix by extending the check to include the hash of bytes 20-29 (source id in PTPv2) that is provided with the timestamps.

| | | | | | | | | | | | | | All the mv88e6xxx drivers use the exact same code in their probe function to lookup the switch name given its ID. Thus introduce a mv88e6xxx_switch_id structure and a mv88e6xxx_lookup_name function in the common mv88e6xxx code. In the meantime make __mv88e6xxx_reg_{read,write} static since we do not need to expose these low-level r/w routines anymore.

* net: encx24j600: Fix SPI id table definitionJavier Martinez Canillas2015-11-021-3/+4
| | | | | | | | | | | | | | | | A driver's SPI id table is expected to be an array of struct spi_device_id that ends with a zero-initialized sentinel entry. But this driver defines the table as a single struct spi_device_id and sets .id_table to a pointer to this struct. But spi_match_id() has a loop that iterates while the struct spi_device_id .name[0] is not NULL, so not having a sentinel can cause a NULL pointer deference error. This patch defines the SPI id table correctly as all other SPI drivers do. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>

But since kernel 3.9 (patch 1d1d1a767206fbe5d4c69493b7e6d2a8d08cc0a0 "mm: only enforce stable page writes if the backing device requires it") it is not assumed anymore that block devices require stable pages. This patch sets the necessary flag to get stable pages back for rbd. In a ceph installation that provides multiple ext4 formatted rbd devices "bad crc" messages appeared regularly (ca 1 message every 1-2 minutes on every OSD that provided the data for the rbd) in the OSD-logs before this patch. After this patch this messages are pretty much gone (only ca 1-2 / month / OSD).

| | * | net/mlx4: Copy/set only sizeof struct mlx4_eqe bytesCarol L Soto2015-10-282-2/+2

If caps.eqe_size is bigger than the struct mlx4_eqe then we corrupt data in the master context. When using a 64 byte stride, the memcpy copied over 63 bytes to the slave_eq structure. This resulted in copying over the entire eqe of interest, including its ownership bit -- and also 31 bytes of garbage into the next WQE in the slave EQ -- which did NOT include the ownership bit (and therefore had no impact). However, once the stride is increased to 128, we are overwriting the ownership bits of *three* eqes in the slave_eq struct. This results in an incorrect ownership bit for those eqes, which causes the eq to seem to be full. The issue therefore surfaced only once 128-byte EQEs started being used in SRIOV and (overarchitectures that have 128/256 byte cache-lines such as PPC) - e.g after commit 77507aa249ae "net/mlx4_core: Enable CQE/EQE stride support".

A memory barrier is required between the read of the descriptor index and the start of the Tx cleanup loop. This allows a change to a lighter-weight barrier in the Tx transmit routine just before updating the current descriptor index. Since the memory barrier does result in extra overhead on arm64, keep the previous change to not chase the current descriptor value. This prevents the execution of the barrier for each loop performed.

Use the right counter. BSY conditions happen when the SoC is under performance stress. Doing *more* work in stress situations by trying to schedule NAPI is not a good idea as the stressed system becomes still more stressed. The Rx interrupt is already at work making sure the NAPI is scheduled. So calling gfar_receive() here does not help. This issue was present since day 1.

With the default config this does not happen because the default Rx offloads (Rx csum and Rx VLAN) properly enable PRSDEP. But if anyone disables all these offloads (via ethtool), we get a wrong configuration were the Rx flow classification and hashing, and other Filer based features (e.g. wake-on-filer interrupt) won't work. This patch fixes the issue. Also, account for Rx FCB insertion which happens every time PRSDEP is set. Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S.

Later we limited this to Dell laptops only because of reports that this broke things on non Dell laptops. Now it turns out that this breaks things on the Dell Latitude D600 too. So it seems that only the Dell Latitude D420/430/620/630, which all share the same touchpad / stick combo, have these separate bits. This patch limits the checking of the separate bits to only these models fixing regressions with other models.
