2020-01-07ionic: restrict received packets to mtu sizeShannon Nelson1-2/+9
Make sure the NIC drops packets that are larger than the specified MTU. The front end of the NIC will accept packets larger than MTU and will copy all the data it can to fill up the driver's posted buffers - if the buffers are not long enough the packet will then get dropped. With the Rx SG buffers allocagted as full pages, we are currently setting up more space than MTU size available and end up receiving some packets that are larger than MTU, up to the size of buffers posted. To be sure the NIC doesn't waste our time with oversized packets we need to lie a little in the SG descriptor about how long is the last SG element. At dealloc time, we know the allocation was a page, so the deallocation doesn't care about what length we put in the descriptor.

Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2020-01-06 This series contains updates to igc to add basic support for timestamping. Vinicius adds basic support for timestamping and enables ptp4l/phc2sys to work with i225 devices. Initially, adds the ability to read and adjust the PHC clock. Patches 2 & 3 enable and retrieve hardware timestamps. Patch 4 implements the ethtool ioctl that ptp4l uses to check what timestamping methods are supported. Lastly, added support to do timestamping using the "Start of Packet" signal from the PHY, which is now supported in i225 devices. While i225 does support multiple PTP domains, with multiple timestamping registers, we currently only support one PTP domain and use only one of the timestamping registers for implementation purposes. ==================== Signed-off-by: David S.

The main difference from i210 is that i225 has support for choosing the timer register to use when timestamping packets. Right now, we only support using timer 0.

2020-01-06Merge branch 'ethtool-allow-nesting-of-begin-and-complete-callbacks'David S. Miller4-33/+32
Michal Kubecek says: ==================== ethtool: allow nesting of begin() and complete() callbacks The ethtool ioctl interface used to guarantee that ethtool_ops callbacks were always called in a block between calls to ->begin() and ->complete() (if these are defined) and that this whole block was executed with RTNL lock held: rtnl_lock(); ops->begin(); /* other ethtool_ops calls */ ops->complete(); rtnl_unlock(); This prevented any nesting or crossing of the begin-complete blocks. However, this is no longer guaranteed even for ioctl interface as at least ethtool_phys_id() releases RTNL lock while waiting for a timer. With the introduction of netlink ethtool interface, the begin-complete pairs are naturally nested e.g. when a request triggers a netlink notification. Fortunately, only minority of networking drivers implements begin() and complete() callbacks and most of those that do, fall into three groups: - wrappers for pm_runtime_get_sync() and pm_runtime_put() - wrappers for clk_prepare_enable() and clk_disable_unprepare() - begin() checks netif_running() (fails if false), no complete() First two have their own refcounting, third is safe w.r.t. nesting of the blocks. Only three in-tree networking drivers need an update to deal with nesting of begin() and complete() calls: via-velocity and epic100 perform resume and suspend on their own and wil6210 completely serializes the calls using its own mutex (which would lead to a deadlock if a request request triggered a netlink notification).

Unlike most networking drivers using begin() and complete() ethtool_ops callbacks to resume a device which is down and suspend it again when done, epic100 does not use standard refcounted infrastructure but sets device sleep state directly. With the introduction of netlink ethtool interface, we may have nested begin-complete blocks so that inner complete() would put the device back to sleep for the rest of the outer block. To avoid rewriting an old and not very actively developed driver, just add a nesting counter and only perform resume and suspend on the outermost level.

2020-01-06wil6210: get rid of begin() and complete() ethtool_opsMichal Kubecek1-27/+16
The wil6210 driver locks a mutex in begin() ethtool_ops callback and unlocks it in complete() so that all ethtool requests are serialized. This is not going to work correctly with netlink interface; e.g. when ioctl triggers a netlink notification, netlink code would call begin() again while the mutex taken by ioctl code is still held by the same task. Let's get rid of the begin() and complete() callbacks and move the mutex locking into the remaining ethtool_ops handlers except get_drvinfo which only copies strings that are not changing so that there is no need for serialization.

The recent MD5 tests added duplicate configuration in the default VRF. This change exposed a bug in existing tests designed to verify no connection when client and server are not in the same domain. The server should be running bound to the vrf device with the client run in the default VRF (the -2 option is meant for validating connection data). Fix the option for both tests. While technically this is a bug in previous releases, the tests are properly failing since the default VRF does not have any routing configuration so there really is no need to backport to prior releases.

Huazhong Tan says: ==================== net: hns3: misc updates for -net-next This series includes some misc updates for the HNS3 ethernet driver. [patch 1] adds trace events support. [patch 2] re-organizes TQP's vector handling. [patch 3] renames the name of TQP vector. [patch 4] rewrites a log in the hclge_map_ring_to_vector(). [patch 5] modifies the name of misc IRQ vector. [patch 6] handles the unexpected speed 0 return from HW. [patch 7] replaces an unsuitable variable type. [patch 8] modifies an unsuitable reset level for HW error. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-01-06net: hns3: modify an unsuitable reset level for hardware errorHuazhong Tan1-2/+2
According to hardware user manual, when hardware reports error 'roc_pkt_without_key_port', the driver should assert function reset to do the recovery. So this patch uses HNAE3_FUNC_RESET to replace HNAE3_GLOBAL_RESET. Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-01-06net: hns3: replace an unsuitable variable type in hclge_inform_reset_assert_to_vf()Huazhong Tan2-1/+4
In hclge_inform_reset_assert_to_vf(), variable reset_type(enum type) will be copied into msg_data whose size is 2 bytes. Currently, hip08 is a little-endian machine, so the lower two bytes of reset_type will be copied to msg_data. But when running on a big-endian machine, msg_data will have a wrong value(the higher two bytes of reset_type). So this patch modifies the type of reset_type to u16, and adds a build check in case enum hnae3_reset_type has value larger than U16_MAX.

2020-01-06net: hns3: modify the IRQ name of misc vectorsYonglong Liu5-4/+10
The misc IRQ of all the devices have the same name, so it's hard to find the right misc IRQ of the device. This patch modifies the misc IRQ names as "hclge/hclgevf"-misc- "pci name". And now the IRQ name is not related to net device name anymore, so change the HNAE3_INT_NAME_LEN to 32 bytes, and that is enough.
