In the bridge driver we usually have the same function working for both port and bridge. In order to follow that logic and also avoid code duplication, consolidate the bridge_ and brport_ linkxstats calls into one since they share most of their code. As a side effect this allows us to dump the vlan stats also via the slave call which is in preparation for the upcoming per-port vlan stats and vlan flag dumping. Signed-off-by:

Hadar Hen Zion says: ==================== net_sched, flow_dissector, flower: Introduce vlan tag support This patchset introduce vlan tag support to the flower classifier and the flow dissector. In addition to adding vlan priority to act vlan. The first 2 patches are dealing with flow-dissector: - The first patch is a fix, in case the vlan was already stripped from the skb, take it from skb->vlan_tci. - The second patch adds support for vlan priority. The next 2 patches are dealing with flower: - The first patch is a fix, sets flow dissector 'used_keys' according to the mask value of each key. - The secound patch adds vlan tag support to the flower classifier, user space patches will be sent later to complete it. The last patch adds vlan priority to act vlan since only vlan id is currently supported. Changes from V1: - A new patch was added to this series "net_sched: flower: Avoid dissection of unmasked keys" - Adding u16 padding to struct flow_dissector_key_vlan - change flow_label field in struct flow_dissector_key_tags form 20 bits field to u32 - Remove 'if (v->tcfv_push_prio)' check from tcf_vlan_dump function - Add support to un-stripped vlan skb and skb with multipale vlans in __skb_flow_dissect ==================== Signed-off-by:

The current flower implementation checks the mask range and set all the keys included in that range as "used_keys", even if a specific key in the range has a zero mask. This behavior can cause a false positive return value of dissector_uses_key function and unnecessary dissection in __skb_flow_dissect. This patch checks explicitly the mask of each key and "used_keys" will be set accordingly. Fixes: 77b9900e ('tc: introduce Flower classifier') Signed-off-by:

Add vlan priority check to the flow dissector by adding new flow dissector struct, flow_dissector_key_vlan which includes vlan tag fields. vlan_id and flow_label fields were under the same struct (flow_dissector_key_tags). It was a convenient setting since struct flow_dissector_key_tags is used by struct flow_keys and by setting vlan_id and flow_label under the same struct, we get precisely 24 or 48 bytes in flow_keys from flow_dissector_key_basic. Now, when adding vlan priority support, the code will be cleaner if flow_label and vlan tag won't be under the same struct anymore. Signed-off-by:

Early in the datapath skb_vlan_untag function is called, stripped the vlan from the skb and set skb->vlan_tci and skb->vlan_proto fields. The current dissection doesn't handle stripped vlan packets correctly. In some flows, vlan doesn't exist in skb->data anymore when applying flow dissection on the skb, fix that. In case vlan info wasn't stripped before applying flow_dissector (RPS flow for example), or in case of skb with multiple vlans (e.g. 802.1ad), get the vlan info from skb->data. The flow_dissector correctly skips any number of vlans and stores only the first level vlan. Fixes: 0744dd00 ('net: introduce skb_flow_dissect()') Signed-off-by:

Gangfeng Huang provides all the changes in the series to update the igb driver to support advanced receive side filters that direct receive packets by flows to different hardware queues. This enables a tight control on routing a flow in the platform. First patch allows for receive network flow classification to insert and remove receive filters by ethtool. Second and third patches add the ability to insert and remove ethertype and VLAN priority filters by ethtool.

Jiri Kosina says: ==================== qdisc-hashtable fixes The following two patches fix all the issues that have been reported against the conversion of qdisc linked list to hashtable (currently in net-next) so far. First patch adjusts handling of singleton qdiscs to the new semantics, and is rather straightforward. The second patch, which fixes "cosmetic" issue of duplicate entries in the qdisc dump for ingress qdiscs, is a little bit more hairy; I personally would love to see all the already existing "if (ingress)"-like hacks go away (by, let's say, introducing a general TCQ_F_? flag), but that's way out of scope of this patchset (but already on my todo). Thanks a lot to Daniel Borkmann and David Ahern for reporting the issues and testing the patches promptly. ==================== Signed-off-by:

tc_dump_qdisc() performs dumping of the per-device qdiscs in two phases; first, the "standard" dev->qdisc is being dumped. Second, if there is/are ingress queue(s), they are being dumped as well. After conversion of netdevice's qdisc linked-list into hashtable, these two sets are not in two disjunctive sets/lists any more, but are both "reachable" directly from netdevice's hashtable. As a consequence, the "full-depth" dump of the ingress qdiscs results in immediately hitting the netdevice hashtable again, and duplicating the dump that has already been performed for dev->qdisc. What in fact needs to be dumped in case of ingress queue is "just" the top-level ingress qdisc, as everything else has been dumped already. Fix this by extending tc_dump_qdisc_root() in a way that it can be instructed whether it should (while performing the "full" per-netdev qdisc dump) perform the whole recursion, or just dump "additional" top-level (ingress) qdiscs without performing any kind of recursion. This fixes duplicate dumps such as qdisc mq 0: root qdisc pfifo_fast 0: parent :4 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc pfifo_fast 0: parent :3 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc pfifo_fast 0: parent :2 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc pfifo_fast 0: parent :1 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc clsact ffff: parent ffff:fff1 qdisc pfifo_fast 0: parent :4 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc pfifo_fast 0: parent :3 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc pfifo_fast 0: parent :2 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 qdisc pfifo_fast 0: parent :1 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 Fixes: 59cc1f61 ("net: sched: convert qdisc linked list to hashtable") Reported-by:

qdisc_match_from_root() is now iterating over per-netdevice qdisc hashtable instead of going through a linked-list of qdiscs (independently on the actual underlying netdev), which was the case before the switch to hashtable for qdiscs. For singleton qdiscs, there is no underlying netdev associated though, and therefore dumping a singleton qdisc will panic, as qdisc_dev(root) will always be NULL.

Jon Maloy says: ==================== tipc: bearer and link improvements The first commit makes it possible to set and check the 'blocked' state of a bearer from the generic bearer layer. The second commit is a small improvement to the link congestion mechanism. ==================== Signed-off-by:
David S. Miller <davem@davemloft.net>
-
Jon Paul Maloy authored
When a link is attempted woken up after congestion, it uses a different, more generous criteria than when it was originally declared congested. This has the effect that the link, and the sending process, sometimes will be woken up unnecessarily, just to immediately return to congestion when it turns out there is not not enough space in its send queue to host the pending message. This is a waste of CPU cycles. We now change the function link_prepare_wakeup() to use exactly the same criteria as tipc_link_xmit(). However, since we are now excluding the window limit from the wakeup calculation, and the current backlog limit for the lowest level is too small to house even a single maximum-size message, we have to expand this limit. We do this by evaluating an alternative, minimum value during the setting of the importance limits. Acked-by:

Jon Paul Maloy authored
In commit 5b7066c3 ("tipc: stricter filtering of packets in bearer layer") we introduced a method of filtering out messages while a bearer is being reset, to avoid that links may be re-created and come back in working state while we are still in the process of shutting them down. This solution works well, but is limited to only work with L2 media, which is insufficient with the increasing use of UDP as carrier media. We now replace this solution with a more generic one, by introducing a new flag "up" in the generic struct tipc_bearer. This field will be set and reset at the same locations as with the previous solution, while the packet filtering is moved to the generic code for the sending side. On the receiving side, the filtering is still done in media specific code, but now including the UDP bearer. Acked-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-08-18 This series contains updates to i40e and i40evf only. Wei Yongjun updates i40e to use list_move() instead of list_del() & list_add() operations. Anjali fixes an issue where the client->open call was not protected with the client instance mutex, which allowed client->close to be called before the open all completed. Catherine makes sure that the VLAN count (and stats) gets reset to 0 after reset. Jake provides two patches, first adds the needed rtnl lock around i40evf_set_interrupt_capability() since i40evf_init_task() does not hold the rtnl_lock. Second fixes an issue where users could reduce the number of channels (queues) below the current flow director filter rules targets. Dave fixes a problem where a static analysis tool generates a warning so eliminating the irrelevant check and redundant assignment for the value of enabled_tc. Avinash fixes an sync issue where the iWARP device open is called before the PCI register writes are completed, so ensure the register writes complete before exiting the setup function. Alan fixes a bug which causes RSS to continue to work after being disabled. Carolyn implements a feature change which allows using ethtool to set RDD hash options using less than four parameters if desired. Dan Carpenter cleans up a stray unlock.

After disabling RSS, traffic would continue to be assigned to different queues instead of falling back to a single queue. Without this patch, attempting to disable RSS would not work as expected. This patch fixes the bug by clearing the lookup table used by RSS such that all traffic is assigned to a single queue. This patch also addresses the issue of reinstating the lookup table should RSS then be re-enabled. Change-ID: Ib20c7c6a7e9f1f772bb787370f8a8c664796b141 Signed-off-by:

VF goes through reset path during VF creation which happens to also have notification of VF reset to client. Adding conditional check to avoid wrongly notifying VF reset during VF creation. Also changing the call order of VF enable, calling it after VF creation rather than before. Change-ID: I96eabd99deae746a2f0fc465194c886f196178ce Signed-off-by:

This patch is a fix for the bug i.e. unable to create iwarp device in VF. This is a sync issue and the iwarp device open is called even before the PCI register writes are done. Forcing the PCI register writes to happen just before it exits the function. Change-ID: I60c6a2c709da89e845f2764cc50ce8b7373c8c44 Signed-off-by:

If a driver is unable to maintain all current user supplied settings from ethtool (or other sources), it is not ok for a user request to succeed and silently trample over previous configuration. To that end, if you change the number of channels, it must not be allowed to reduce the number of channels (queues) below the current flow director filter rules targets. In this case, return -EINVAL when a request to reduce the number of channels would do so. In addition log a warning to the kernel buffer explaining why we failed, and report the rules which prevent us from lowering the number of channels.

This patch fixes a problem where a static analysis tool generates a warning for "INVARIANT_CONDITION: Expression 'enabled_tc' used in the condition always yields the same result." Without this patch, the driver will not pass the static analysis tool checks without generating warnings. This patch fixes the problem by eliminating the irrelevant check and redundant assignment for the value of enabled_tc. Change-ID: Ia7d44cb050f507df7de333e96369d322e08bf408 Signed-off-by:

The function calls netif_set_real_num_(tx|rx)_queues, both of which should be done only under rntl lock. Unfortunately the i40evf_init_task did not hold the rtnl_lock as necessary. This patch adds the locking needed. Change-ID: Ib72a21c3ce22b71a226b16f9bbe0f5f8cc3e849b Signed-off-by:
