Bert Kenward says: ==================== Basic support for Solarflare 8000 series NICs The upcoming Solarflare 8000 series 10G/40G network card supports a similar interface to the current 7000 series cards. This patch series provides basic support for these cards, making no use of any new functionality. v2: fix indenting in ef10.c in patch 1/2. ==================== Signed-off-by: -

The Solarflare 8000 series NIC will use a new TSO scheme. The current driver refuses to load if the current TSO scheme is not found. Remove that check and instead make the TSO version a per-queue parameter. Signed-off-by:

This module allows to insert errors in some of netdevice's notifier events. All network drivers use these notifiers to signal various events and to check if they are allowed, e.g. PRECHANGEMTU and CHANGEMTU afterwards. Until recently I had to run failure tests by injecting a custom module, but now this infrastructure makes it trivial to test these failure paths. Some of the recent bugs I fixed were found using this module. Here's an example: $ cd /sys/kernel/debug/notifier-error-inject/netdev $ echo -22 > actions/NETDEV_CHANGEMTU/error $ ip link set eth0 mtu 1024 RTNETLINK answers: Invalid argument CC: Akinobu Mita <akinobu.mita@gmail.com> CC: "David S.

There are several issues in hv_netvsc driver with regards to link status change handling: - RNDIS_STATUS_NETWORK_CHANGE results in calling userspace helper doing '/etc/init.d/network restart' and this is inappropriate and broken for many reasons. - link_watch infrastructure only sends one notification per second and in case of e.g. paired disconnect/connect events we get only one notification with last status. This makes it impossible to handle such situations in userspace. Redo link status changes handling in the following way: - Create a list of reconfig events in network device context. - On a reconfig event add it to the list of events and schedule netvsc_link_change(). - In netvsc_link_change() ensure 2-second delay between link status changes. - Handle RNDIS_STATUS_NETWORK_CHANGE as a paired disconnect/connect event.

The current unix_dgram_recvmsg does a wake up for every received datagram. This seems wasteful as only SOCK_DGRAM client sockets in an n:1 association with a server socket will ever wait because of the associated condition. The patch below changes the function such that the wake up only happens if wq_has_sleeper indicates that someone actually wants to be notified. Testing with SOCK_SEQPACKET and SOCK_DGRAM socket seems to confirm that this is an improvment. Signed-Off-By:

Nikolay Aleksandrov says: ==================== net: ipmr: more cleanups and mfc netlink support This set continues with the minor cleanups in the first 6 patches and patch 7 adds the first new feature - MFC manipulation via netlink. It registers NEWROUTE/DELROUTE for that purpose and uses the same semantics as the already present netlink dump. The only new attribute that is used is RTA_PREFSRC to denote an MFC_PROXY entry. Currently the table must exist before adding an entry, and new tables can be created only via setsockopt, but that will be changed in the future. This set was tested with modified iproute2 which supports NEWROUTE/DELROUTE for RTNL_FAMILY_IPMR. ==================== Signed-off-by: -

This patch adds support to add and remove MFC entries. It uses the same attributes like the already present dump support in order to be consistent. There's one new entry - RTA_PREFSRC, it's used to denote an MFC_PROXY entry (see MRT_ADD_MFC vs MRT_ADD_MFC_PROXY). The already existing infrastructure is used to create and delete the entries, the netlink message gets converted internally to a struct mfcctl which is used with ipmr_mfc_add/delete. The other used attributes are: RTA_IIF - used for mfcc_parent (when adding it's required to be valid) RTA_SRC - used for mfcc_origin RTA_DST - used for mfcc_mcastgrp RTA_TABLE - the MRT table id RTA_MULTIPATH - the "oifs" ttl array Signed-off-by:

MFC_NOTIFY was introduced in kernel 2.1.68 but afaik it hasn't been used and I couldn't find any users currently so just remove it. Only MFC_STATIC is left, so move it into an enum, add a description and use BIT(). Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-11-25 This series contains updates to fm10k, i40e and i40evf. Alex Duyck fixes up fm10k to use napi_schedule_irqoff() instead of napi_schedule() since the function it is called from runs from hard interrupt context or with interrupts already disabled in netpoll. Shannon cleans up i40e and i40evf unused cd_tunneling parameter and any code comments that refer to it. Then clean up a few instances of BUG_ON, based on a Linux diatribe, especially when WARN_ON can be used. Helin fixed a issue where using ethtool RXNFC command could let receive flow hash could be set on disabled queues, so resolve by returning the number of enabled queues before setting RXNFC. Anjali fixes a MSS issue where the hardware/NVM sets a limit of no less than 256 bytes for MSS, yet the stack can send as low as 76 byte MSS. Fixed the issue by lowering the hardware limit to 64 bytes to avoid MDDs from firing and causing a reset when the MSS is lower than 256. Added a statistic to track how many times we forced to do a write back on transmit if the number of descriptors pending are less than a cache line. Catherine fixes link status changes, where polling would only change link status changes in one direction depending on what the last old data saved off was. This was due to the watchdog only calling link_event and not handle_link_event. Mitch cleans up and enhances error messages related to VF MAC/VLAN filters. v2: Dropped patch "i40e: Properly cast type for arithmetic" patch based on feedback from the community ==================== Signed-off-by: -

When a lot (many hundreds) of MAC or VLAN filters are added at one time, we can overflow the Admin Queue buffer size with all the requests. Unfortunately, the driver would then calculate the message size incorrectly, causing it to be rejected by the PF. Furthermore, there was no mechanism to trigger another request to allow for configuring the rest of the filters that didn't fit into the first request. To fix this, recalculate the correct buffer size when we detect the overflow condition instead of just assuming the max buffer size. Also, don't clear the request bit in adapter->aq_required when we have an overflow, so that the rest of the filters can be processed later.

The watchdog only calls link_event not handle_link_event which means that we need to save the old information in link_event. Previously when polling we were comparing current data to the old data saved the last time we actually received a link event. This means that the polling would only fix link status changes in one direction depending on what the last old data saved off was. Change-ID: Ie590f30fdbcb133d0ddad4e07e3eb1aad58255b3 Signed-off-by:

There's no need to kill the kernel thread here. If this condition was true, the probe() would have died long before we got here. In any case, we'll get the same result when this code tries to use the VSI pointer being checked. Prompted by a recent Linus diatribe.

There's really no reason to kill the kernel thread just because of a little info string. This reworks the code to use snprintf's limiting to assure that the string is never too long, and WARN_ON to still put out a warning that we might want to look at the feature list length.
