2016-12-19rtc: mcp795: fix month write resetting date to 1.Emil Bartczak1-5/+81
According to Microchip errata some combinations of date and month values may result in the date being reset to 1, even if the date is also written with the month (for example 31-07 or 31-08). As a workaround avoid writing date and month values within the same Write command. Instead, terminate the Write command after loading the date and begin a new command to write the month. In addition, disable the oscillator before loading the new values. This is done by ensuring both the ST and EXTOSC bits are cleared and waiting for the OSCON bit to clear.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "The libnvdimm pull request is relatively small this time around due to some development topics being deferred to 4.11. As for this pull request the bulk of it has been in -next for several releases leading to one late fix being added (commit 868f036fee4b ("libnvdimm: fix mishandled nvdimm_clear_poison() return value")). It has received a build success notification from the 0day-kbuild robot and passes the latest libnvdimm unit tests. Summary: - Dynamic label support: To date namespace label support has been limited to disambiguating cases where PMEM (direct load/store) and BLK (mmio aperture) accessed-capacity alias on the same DIMM. Since 4.9 added support for multiple namespaces per PMEM-region there is value to support namespace labels even in the non-aliasing case. The presence of a valid namespace index block force-enables label support when the kernel would otherwise rely on region boundaries, and permits the region to be sub-divided. - Handle media errors in namespace metadata: Complement the error handling for media errors in namespace data areas with support for clearing errors on writes, and downgrading potential machine-check exceptions to simple i/o errors on read. - Device-DAX region attributes: Add 'align', 'id', and 'size' as attributes for device-dax regions. In particular this enables userspace tooling to generically size memory mapping and i/o operations. Prevent userspace from growing assumptions / dependencies about the parent device topology for a dax region. A libnvdimm namespace may not always be the parent device of a dax region. - Various cleanups and small fixes" * tag 'libnvdimm-for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: dax: add region 'id', 'size', and 'align' attributes libnvdimm: fix mishandled nvdimm_clear_poison() return value libnvdimm: replace mutex_is_locked() warnings with lockdep_assert_held libnvdimm, pfn: fix align attribute libnvdimm, e820: use module_platform_driver libnvdimm, namespace: use octal for permissions libnvdimm, namespace: avoid multiple sector calculations libnvdimm: remove else after return in nsio_rw_bytes() libnvdimm, namespace: fix the type of name variable libnvdimm: use consistent naming for request_mem_region() nvdimm: use the right length of "pmem" libnvdimm: check and clear poison before writing to pmem tools/testing/nvdimm: dynamic label support libnvdimm: allow a platform to force enable label support libnvdimm: use generic iostat interfaces

While this information is available by looking at the nvdimm parent device that may not always be the case when/if we add support for other memory regions. Tooling should not depend on walking a given ancestor topology that is not guaranteed by the device's class. For example, a device-dax instance will always have a dax_region parent, but it may not always have a libnvdimm "dax" device as a grandparent.

2016-12-17virtio_net: xdp, add slowpath case for non contiguous buffersJohn Fastabend1-1/+74
virtio_net XDP support expects receive buffers to be contiguous. If this is not the case we enable a slowpath to allow connectivity to continue but at a significan performance overhead associated with linearizing data. To make it painfully aware to users that XDP is running in a degraded mode we throw an xdp buffer error. To linearize packets we allocate a page and copy the segments of the data, including the header, into it. After this the page can be handled by XDP code flow as normal. Then depending on the return code the page is either freed or sent to the XDP xmit path. There is no attempt to optimize this path. This case is being handled simple as a precaution in case some unknown backend were to generate packets in this form. To test this I had to hack qemu and force it to generate these packets. I do not expect this case to be generated by "real" backends. Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-12-17virtio_net: add XDP_TX supportJohn Fastabend1-7/+93
This adds support for the XDP_TX action to virtio_net. When an XDP program is run and returns the XDP_TX action the virtio_net XDP implementation will transmit the packet on a TX queue that aligns with the current CPU that the XDP packet was processed on. Before sending the packet the header is zeroed. Also XDP is expected to handle checksum correctly so no checksum offload support is provided.

2016-12-17virtio_net: add dedicated XDP transmit queuesJohn Fastabend1-2/+28
XDP requires using isolated transmit queues to avoid interference with normal networking stack (BQL, NETDEV_TX_BUSY, etc). This patch adds a XDP queue per cpu when a XDP program is loaded and does not expose the queues to the OS via the normal API call to netif_set_real_num_tx_queues(). This way the stack will never push an skb to these queues. However virtio/vhost/qemu implementation only allows for creating TX/RX queue pairs at this time so creating only TX queues was not possible. And because the associated RX queues are being created I went ahead and exposed these to the stack and let the backend use them. This creates more RX queues visible to the network stack than TX queues which is worth mentioning but does not cause any issues as far as I can tell.

2016-12-17virtio_net: Add XDP supportJohn Fastabend1-5/+171
This adds XDP support to virtio_net. Some requirements must be met for XDP to be enabled depending on the mode. First it will only be supported with LRO disabled so that data is not pushed across multiple buffers. Second the MTU must be less than a page size to avoid having to handle XDP across multiple pages. If mergeable receive is enabled this patch only supports the case where header and data are in the same buf which we can check when a packet is received by looking at num_buf. If the num_buf is greater than 1 and a XDP program is loaded the packet is dropped and a warning is thrown. When any_header_sg is set this does not happen and both header and data is put in a single buffer as expected so we check this when XDP programs are loaded. Subsequent patches will process the packet in a degraded mode to ensure connectivity and correctness is not lost even if backend pushes packets into multiple buffers. If big packets mode is enabled and MTU/LRO conditions above are met then XDP is allowed. This patch was tested with qemu with vhost=on and vhost=off where mergeable and big_packet modes were forced via hard coding feature negotiation. Multiple buffers per packet was forced via a small test patch to vhost.c in the vhost=on qemu mode.

2016-12-17net: vrf: Drop conntrack data after pass through VRF device on TxDavid Ahern1-0/+4
Locally originated traffic in a VRF fails in the presence of a POSTROUTING rule. For example, $ iptables -t nat -A POSTROUTING -s 11.1.1.0/24 -j MASQUERADE $ ping -I red -c1 11.1.1.3 ping: Warning: source address might be selected on device other than red. PING 11.1.1.3 (11.1.1.3) from 11.1.1.2 red: 56(84) bytes of data. ping: sendmsg: Operation not permitted Worse, the above causes random corruption resulting in a panic in random places (I have not seen a consistent backtrace). Call nf_reset to drop the conntrack info following the pass through the VRF device. The nf_reset is needed on Tx but not Rx because of the order in which NF_HOOK's are hit: on Rx the VRF device is after the real ingress device and on Tx it is is before the real egress device. Connection tracking should be tied to the real egress device and not the VRF device.
