2019-02-06net: stmmac: fix ptp timestamping on Rx on gmac4Ilias Apalodimas
The current driver only enables Pdelay_Req and Pdelay_Resp when HWTSTAMP_FILTER_PTP_V2_EVENT, HWTSTAMP_FILTER_PTP_V1_L4_EVENT or HWTSTAMP_FILTER_PTP_V2_L4_EVENT is requested. This results in ptp sync on slave mode to report 'received SYNC without timestamp' when using ptp4l. Although the hardware can support Sync, Pdelay_Req and Pdelay_resp by setting bit14 annd bits 17/16 to 01 this leaves Delay_Req timestamps out. Fix this by enabling all event and general messages timestamps. This includes SYNC, Follow_Up, Delay_Req, Delay_Resp, Pdelay_Req, Pdelay_Resp and Pdelay_Resp_Follow_Up messages.

2019-02-06net: dsa: mv88e6xxx: Prevent suspend to RAMMiquel Raynal
On one hand, the mv88e6xxx driver has a work queue called in loop which will attempt register accesses after MDIO bus suspension, that entirely freezes the platform during suspend. On the other hand, the DSA core is not ready yet to support suspend to RAM operation because so far there is no way to recover reliably the switch configuration. To avoid the kernel to freeze when suspending with a switch driven by the mv88e6xxx driver, we choose to prevent the driver suspension and in the same way, the whole platform.

2019-02-06net/mlx5e: Update hw flows when encap source mac changedTonghao Zhang
When we offload tc filters to hardware, hardware flows can be updated when mac of encap destination ip is changed. But we ignore one case, that the mac of local encap ip can be changed too, so we should also update them. To fix it, add route_dev in mlx5e_encap_entry struct to save the local encap netdevice, and when mac changed, kernel will flush all the neighbour on the netdevice and send NETEVENT_NEIGH_UPDATE event. The mlx5 driver will delete the flows and add them when neighbour available again.

2019-02-06PCI: Work around Synopsys duplicate Device ID (HAPS USB3, NXP i.MX)Thinh Nguyen
There are at least four different parts with the same Vendor and Device ID ([16c3:abcd]): 1) Synopsys HAPS USB3 controller 2) Synopsys PCIe Root Port in Freescale/NXP i.MX6Q (reported by Lucas) 3) Synopsys PCIe Root Port in Freescale/NXP i.MX6QP (reported by Lukas) 4) Synopsys PCIe Root Port in Freescale/NXP i.MX7D (reported by Trent) The HAPS USB3 controller has a Class Code of PCI_CLASS_SERIAL_USB_XHCI, which means the XHCI driver would normally claim it. Previously, quirk_synopsys_haps() changed the Class Code of all [16c3:abcd] devices, including the Root Ports, to PCI_CLASS_SERIAL_USB_DEVICE to prevent the XHCI driver from claiming them so dwc3-haps can claim them instead. Changing the Class Code of the Root Ports prevents the PCI core from handling them as bridges, so devices below them don't work. Restrict the quirk so it only changes the Class Code for devices that start with the PCI_CLASS_SERIAL_USB_XHCI Class Code, leaving the Root Ports alone.

2019-02-07timex: use __kernel_timex internallyDeepa Dinamani
struct timex is not y2038 safe. Replace all uses of timex with y2038 safe __kernel_timex. Note that struct __kernel_timex is an ABI interface definition. We could define a new structure based on __kernel_timex that is only available internally instead. Right now, there isn't a strong motivation for this as the structure is isolated to a few defined struct timex interfaces and such a structure would be exactly the same as struct timex. The patch was generated by the following coccinelle script: virtual patch @depends on patch forall@ identifier ts; expression e; @@ ( - struct timex ts; + struct __kernel_timex ts; | - struct timex ts = {}; + struct __kernel_timex ts = {}; | - struct timex ts = e; + struct __kernel_timex ts = e; | - struct timex *ts; + struct __kernel_timex *ts; | (memset \| copy_from_user \| copy_to_user \)(..., - sizeof(struct timex)) + sizeof(struct __kernel_timex)) ) @depends on patch forall@ identifier ts; identifier fn; @@ fn(..., - struct timex *ts, + struct __kernel_timex *ts, ...) { ... } @depends on patch forall@ identifier ts; identifier fn; @@ fn(..., - struct timex *ts) { + struct __kernel_timex *ts) { ... } Signed-off-by: Deepa Dinamani <deepa.kernel@gmail.com> Cc: linux-alpha@vger.kernel.org Cc: netdev@vger.kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2019-02-06dm: don't use bio_trim() afterallMike Snitzer
bio_trim() has an early return, which makes it _not_ idempotent, if the offset is 0 and the bio's bi_size already matches the requested size. Prior to DM, all users of bio_trim() were fine with this. But DM has exposed the fact that bio_trim()'s early return is incompatible with a cloned bio whose integrity payload must be trimmed via bio_integrity_trim(). Fix this by reverting DM back to doing the equivalent of bio_trim() but in an idempotent manner (so bio_integrity_trim is always performed). Follow-on work is needed to assess what benefit bio_trim()'s early return is providing to its existing callers.

2019-02-06dm: add memory barrier before waitqueue_activeMikulas Patocka
Block core changes to switch bio-based IO accounting to be percpu had a side-effect of altering DM core to now rely on calling waitqueue_active (in both bio-based and request-based) to check if another task is in dm_wait_for_completion(). A memory barrier is needed before calling waitqueue_active(). DM core doesn't piggyback on a preceding memory barrier so it must explicitly use its own. For more details on why using waitqueue_active() without a preceding barrier is unsafe, please see the comment before the waitqueue_active() definition in include/linux/wait.h. Add the missing memory barrier by switching to using wq_has_sleeper().

2019-02-06dpaa2-eth: Update buffer pool refill thresholdIoana Ciocoi Radulescu
Add more buffers to the Rx buffer pool as soon as 7 of them get consumed, instead of waiting for their number to drop below a fixed threshold. 7 is the number of buffers that can be released in the pool via a single DPIO command.

2019-02-06dpaa2-eth: Use FQ-based DPIO enqueue APIIoana Ciocoi Radulescu
Starting with MC10.14.0, dpaa2_io_service_enqueue_fq() API is functional. Since there are a number of cases where it offers better performance compared to the currently used enqueue function, switch to it for firmware versions that support it.

2019-02-06dpaa2-eth: Use napi_consume_skb()Ioana Ciocoi Radulescu
While in NAPI context, free skbs by calling napi_consume_skb() instead of dev_kfree_skb(), to take advantage of the bulk freeing mechanism. Signed-off-by: Ioana Radulescu <ruxandra.radulescu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-06dpaa2-eth: Use a single page per Rx bufferIoana Ciocoi Radulescu
Instead of allocating page fragments via the network stack, use the page allocator directly. For now, we consume one page for each Rx buffer. With the new memory model we are free to consider adding more XDP support. Performance decreases slightly in some IP forwarding cases. No visible effect on termination traffic. The driver memory footprint increases as a result of this change, but it is still small enough to not really matter. Another side effect is that now Rx buffer alignment requirements are naturally satisfied without any additional actions needed. Remove alignment related code, except in the buffer layout information conveyed to MC, as hardware still needs to know the alignment value we guarantee.

2019-02-06qede: use ethtool_rx_flow_rule() to remove duplicated parser codePablo Neira Ayuso
The qede driver supports for ethtool_rx_flow_spec and flower, both codebases look very similar. This patch uses the ethtool_rx_flow_rule() infrastructure to remove the duplicated ethtool_rx_flow_spec parser and consolidate ACL offload support around the flow_rule infrastructure. Furthermore, more code can be consolidated by merging qede_add_cls_rule() and qede_add_tc_flower_fltr(), these two functions also look very similar. This driver currently provides simple ACL support, such as 5-tuple matching, drop policy and queue to CPU. Drivers that support more features can benefit from this infrastructure to save even more redundant codebase. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S.

2019-02-06qede: place ethtool_rx_flow_spec after code after TC flower codebasePablo Neira Ayuso
This is a preparation patch to reuse the existing TC flower codebase from ethtool_rx_flow_spec. This patch is merely moving the core ethtool_rx_flow_spec parser after tc flower offload driver code so we can skip a few forward function declarations in the follow up patch.
