Samuel Mendoza-Jonas says: ==================== NCSI VLAN Filtering Support This series (mainly patch 2) adds VLAN filtering to the NCSI implementation. A fair amount of code already exists in the NCSI stack for VLAN filtering but none of it is actually hooked up. This goes the final mile and fixes a few bugs in the existing code found along the way (patch 1). Patch 3 adds the appropriate flag and callbacks to the ftgmac100 driver to enable filtering as it's a large consumer of NCSI (and what I've been testing on). v3: - Add comment describing change to ncsi_find_filter() - Catch NULL in clear_one_vid() from ncsi_get_filter() - Simplify state changes when kicking updated channel ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Register the ndo_vlan_rx_{add,kill}_vid callbacks and set the NETIF_F_HW_VLAN_CTAG_FILTER if NCSI is available. This allows the VLAN core to notify the NCSI driver when changes occur so that the remote NCSI channel can be properly configured to filter on the set VLAN tags.

Samuel Mendoza-Jonas authored
Make use of the ndo_vlan_rx_{add,kill}_vid callbacks to have the NCSI stack process new VLAN tags and configure the channel VLAN filter appropriately. Several VLAN tags can be set and a "Set VLAN Filter" packet must be sent for each one, meaning the ncsi_dev_state_config_svf state must be repeated. An internal list of VLAN tags is maintained, and compared against the current channel's ncsi_channel_filter in order to keep track within the state. VLAN filters are removed in a similar manner, with the introduction of the ncsi_dev_state_config_clear_vids state. The maximum number of VLAN tag filters is determined by the "Get Capabilities" response from the channel. Signed-off-by: -

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-08-27 This series contains updates to i40e and i40evf only. Sudheer updates code comments and state variable so that adminq_subtask will have accutate information whenever it gets scheduled. Mariusz stores information about FEC modes, to be used to printing link states information, so that we do not need to call admin queue when reporting link status. Adds VF support for controlling VLAN tag stripping via ethtool. Jake provides the majority of changes in this series, starting with increasing the size of the prefix buffer so that it can hold enough characters for every possible input, which prevents snprintf truncation. Fixed other string truncation errors/warnings produced by GCC 7.x. Removed an unnecessary workaround for resetting XPS. Fixed an issue where there is a mismatched affinity mask value, so initialize the value to cpu_possible_mask and invert the logic for checking incorrect CPU vs IRQ affinity so that the exceptional case is handled at the check. Removed ULTRA latency mode due to several issues found and will be looking at better solution for small packet workloads. Akeem fixes an issue where the incorrect flag was being used to set promiscuous mode for unicast, which was enabling promiscuous mode only for multicast instead of unicast. Carolyn fixes an issue where an error return value is set, but this value can be overwritten before we actually do exit the function. So remove the error code assignment and add code comments for better understanding on why we do not need to set and return the error. ==================== Signed-off-by: -

Greg Kroah-Hartman says: ==================== irda: move it to drivers/staging so we can delete it The IRDA code has long been obsolete and broken. So, to keep people from trying to use it, and to prevent people from having to maintain it, let's move it to drivers/staging/ so that we can delete it entirely from the kernel in a few releases. ==================== Signed-off-by: -

It's time to get rid of IRDA. It's long been broken, and no one seems to use it anymore. So move it to staging and after a while, we can delete it from there. To start, move the network irda core from net/irda to drivers/staging/irda/net/ Signed-off-by:

Hyper-V Sockets (hv_sock) supplies a byte-stream based communication mechanism between the host and the guest. It uses VMBus ringbuffer as the transportation layer. With hv_sock, applications between the host (Windows 10, Windows Server 2016 or newer) and the guest can talk with each other using the traditional socket APIs. More info about Hyper-V Sockets is available here: "Make your own integration services": https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/make-integration-service The patch implements the necessary support in Linux guest by introducing a new vsock transport for AF_VSOCK.

The xen driver initializes struct ubuf_info fields using designated initializers. I recently moved these fields inside a nested anonymous struct inside an anonymous union. I had missed this use case.

John Fastabend says: ==================== sockmap UAPI updates and fixes This series updates sockmap UAPI, adds additional test cases and provides a couple fixes. First the UAPI changes. The original API added two sockmap specific API artifacts (a) a new map_flags field with a sockmap specific update command and (b) a new sockmap specific attach field in the attach data structure. After this series instead of attaching programs with a single command now two commands are used to attach programs to maps individually. This allows us to add new programs easily in the future and avoids any specific sockmap data structure additions. The map_flags field is also removed and instead we allow socks to be added to multiple maps that may or may not have programs attached. This allows users to decide if a sock should run a SK_SKB program type on receive based on the map it is attached to. This is a nice improvement. See patches for specific details. More test cases were added to test above changes and also stress test the interface. Finally two fixes/improvements were made. First a missing rcu section was added. Second now sockmap can build without KCM being used to trigger 'y' on CONFIG_STREAM_PARSER by selecting a new BPF config option. ==================== Signed-off-by: -
John Fastabend authored
Sockmap is a bit different than normal stress tests that can run in parallel as is. We need to reuse the same socket pool and map pool to get good stress test cases. Signed-off-by:
