Eric Dumazet says: ==================== net: better lockdep annotations Introduction of qdisc->running seqcount added lockdep false positives. While chasing the bug, it came to me that we had a lot of copies of the same stuff in virtual drivers. This patch series has the qdisc->running fix (considers that a trylock is attempted in lockdep terminology), and adds a generic helper so that we no longer have to patch many virtual drivers when a new per-device or per-qdisc lock is added. Thanks to David Ahern for reporting the issue and testing my patches :) ==================== Signed-off-by:

I'm hitting 5 second timeout in rndis_filter_set_rss_param() while setting RSS parameters for the device. When this happens we end up returning -ETIMEDOUT from the function and rndis_filter_device_add() falls back to setting net_device->max_chn = 1; net_device->num_chn = 1; net_device->num_sc_offered = 0; but after a moment the rndis request succeeds and subchannels start to appear. netvsc_sc_open() does unconditional nvscdev->num_sc_offered-- and it becomes U32_MAX-1. Consequent rndis_filter_device_remove() will hang while waiting for all U32_MAX-1 subchannels to appear and this is not going to happen. The immediate issue could be solved by adding num_sc_offered > 0 check to netvsc_sc_open() but we're getting out of sync with the host and it's not easy to adjust things later, e.g. in this particular case we'll be creating queues without a user request for it and races are expected. Same applies to other parts of the driver which have the same completion timeout. Following the trend in drivers/hv/* code I suggest we remove all these timeouts completely. As a guest we can always trust the host we're running on and if the host screws things up there is no easy way to recover anyway. Signed-off-by:

This series removes these two attributes from cbq and makes kernel reject them via EOPNOTSUPP in case they are present. The two followup changes then remove several features from qdisc infrastructure that are then no longer used/needed.

Earlier commits removed two members from struct Qdisc which places next_sched/gso_skb into a different cacheline than ->state. This restores the struct layout to what it was before the removal. Move the two members, then add an annotation so they all reside in the same cacheline. This adds a 16 byte hole after cpu_qstats. The hole could be closed but as it doesn't decrease total struct size just do it this way. Reported-by:

iproute2 doesn't implement any cbq option that results in this attribute being sent to kernel. To make use of it, user would have to - patch iproute2 - add a class - attach a qdisc to the class (default pfifo doesn't work as q->handle is 0 and cbq_set_police() is a no-op in this case) - re-'add' the same class (tc class change ...) again - user must also specifiy a defmap (e.g. 'split 1:0 defmap 3f'), since this 'police' feature relies on its presence - the added qdisc must be one of bfifo, pfifo or netem If all of these conditions are met and _some_ leaf qdiscs, namely p/bfifo, netem, plug or tbf would drop a packet, kernel calls back into cbq, which will attempt to re-queue the skb into a different class as indicated by the parents' defmap entry for TC_PRIO_BESTEFFORT. [ i.e. we behave as if tc_classify returned TC_ACT_RECLASSIFY ]. This feature, which isn't documented or implemented in iproute2, and isn't implemented consistently (most qdiscs like sfq, codel, etc drop right away instead of attempting this reclassification) is the sole reason for the reshape_fail and __parent member in Qdisc struct. So remove TCA_CBQ_POLICE support from the kernel, reject it via EOPNOTSUPP so userspace knows we don't support it, and then remove no-longer needed infrastructure in followup commit. Signed-off-by:

since initial revision of cbq in 2004 iproute 2 has never implemented support for TCA_CBQ_OVL_STRATEGY, which is what needs to be set to activate the class->drop() call (TC_CBQ_OVL_DROP strategy must be set by userspace value must be set by userspace). David Miller says: It seems really safe to kill this thing off, flag an error if someone tries to set the attribute, and therefore kill off all of the non-default cbq_ovl_*() functions. A followup commit can then remove all .drop qdisc methods since this removed the only caller. Signed-off-by:

David Ahern says: ==================== net: vrf: Improve use of FIB rules Currently, VRFs require 1 oif and 1 iif rule per address family per VRF. As the number of VRF devices increases it brings scalability issues with the increasing rule list. All of the VRF rules have the same format with the exception of the specific table id to direct the lookup. Since the table id is available from the oif or iif in the loopup, the VRF rules can be consolidated to a single rule that pulls the table from the VRF device. This solution still allows a user to insert their own rules for VRFs, including rules with additional attributes. Accordingly, it is backwards compatible with existing setups and allows other policy routing as desired. Hopefully v5 is the charm; my e-waste can is getting full. ==================== Signed-off-by:

All of the VRF rules have the same format with the exception of the specific table id to direct the lookup. Since the table id is available from the oif or iif in the loopup, the VRF rules can be consolidated to a single rule that pulls the table from the VRF device. This patch introduces a new rule attribute l3mdev. The l3mdev rule means the table id used for the lookup is pulled from the L3 master device (e.g., VRF) rather than being statically defined. With the l3mdev rule all of the basic VRF FIB rules are reduced to 1 l3mdev rule per address family (IPv4 and IPv6). If an admin wishes to insert higher priority rules for specific VRFs those rules will co-exist with the l3mdev rule. This capability means current VRF scripts will co-exist with this new simpler implementation. Currently, the rules list for both ipv4 and ipv6 look like this: $ ip ru ls 1000: from all oif vrf1 lookup 1001 1000: from all iif vrf1 lookup 1001 1000: from all oif vrf2 lookup 1002 1000: from all iif vrf2 lookup 1002 1000: from all oif vrf3 lookup 1003 1000: from all iif vrf3 lookup 1003 1000: from all oif vrf4 lookup 1004 1000: from all iif vrf4 lookup 1004 1000: from all oif vrf5 lookup 1005 1000: from all iif vrf5 lookup 1005 1000: from all oif vrf6 lookup 1006 1000: from all iif vrf6 lookup 1006 1000: from all oif vrf7 lookup 1007 1000: from all iif vrf7 lookup 1007 1000: from all oif vrf8 lookup 1008 1000: from all iif vrf8 lookup 1008 ... 32765: from all lookup local 32766: from all lookup main 32767: from all lookup default With the l3mdev rule the list is just the following regardless of the number of VRFs: $ ip ru ls 1000: from all lookup [l3mdev table] 32765: from all lookup local 32766: from all lookup main 32767: from all lookup default (Note: the above pretty print of the rule is based on an iproute2 prototype.

Jon Paul Maloy authored
The node keepalive interval is recalculated at each timer expiration to catch any changes in the link tolerance, and stored in a field in struct tipc_node. We use jiffies as unit for the stored value. This is suboptimal, because it makes the calculation unnecessary complex, including two unit conversions. The conversions also lead to a rounding error that causes the link "abort limit" to be 3 in the normal case, instead of 4, as intended. This again leads to unnecessary link resets when the network is pushed close to its limit, e.g., in an environment with hundreds of nodes or namesapces. In this commit, we do instead let the keepalive value be calculated and stored in milliseconds, so that there is only one conversion and the rounding error is eliminated. We also remove a redundant "keepalive" field in struct tipc_link. This is remnant from the previous implementation. Acked-by:

commit 88e8ac70 ("tipc: reduce transmission rate of reset messages when link is down") revealed a flaw in the node FSM, as defined in the log of commit 66996b6c ("tipc: extend node FSM"). We see the following scenario: 1: Node B receives a RESET message from node A before its link endpoint is fully up, i.e., the node FSM is in state SELF_UP_PEER_COMING. This event will not change the node FSM state, but the (distinct) link FSM will move to state RESETTING. 2: As an effect of the previous event, the local endpoint on B will declare node A lost, and post the event SELF_DOWN to the its node FSM. This moves the FSM state to SELF_DOWN_PEER_LEAVING, meaning that no messages will be accepted from A until it receives another RESET message that confirms that A's endpoint has been reset. This is wasteful, since we know this as a fact already from the first received RESET, but worse is that the link instance's FSM has not wasted this information, but instead moved on to state ESTABLISHING, meaning that it repeatedly sends out ACTIVATE messages to the reset peer A. 3: Node A will receive one of the ACTIVATE messages, move its link FSM to state ESTABLISHED, and start repeatedly sending out STATE messages to node B. 4: Node B will consistently drop these messages, since it can only accept accept a RESET according to its node FSM. 5: After four lost STATE messages node A will reset its link and start repeatedly sending out RESET messages to B. 6: Because of the reduced send rate for RESET messages, it is very likely that A will receive an ACTIVATE (which is sent out at a much higher frequency) before it gets the chance to send a RESET, and A may hence quickly move back to state ESTABLISHED and continue sending out STATE messages, which will again be dropped by B. 7: GOTO 5. 8: After having repeated the cycle 5-7 a number of times, node A will by chance get in between with sending a RESET, and the situation is resolved. Unfortunately, we have seen that it may take a substantial amount of time before this vicious loop is broken, sometimes in the order of minutes. We correct this by making a small correction to the node FSM: When a node in state SELF_UP_PEER_COMING receives a SELF_DOWN event, it now moves directly back to state SELF_DOWN_PEER_DOWN, instead of as now SELF_DOWN_PEER_LEAVING. This is logically consistent, since we don't need to wait for RESET confirmation from of an endpoint that we alread know has been reset. It also means that node B in the scenario above will not be dropping incoming STATE messages, and the link can come up immediately. Finally, a symmetry comparison reveals that the FSM has a similar error when receiving the event PEER_DOWN in state PEER_UP_SELF_COMING. Instead of moving to PERR_DOWN_SELF_LEAVING, it should move directly to SELF_DOWN_PEER_DOWN. Although we have never seen any negative effect of this logical error, we choose fix this one, too. The node FSM looks as follows after those changes: +----------------------------------------+ | PEER_DOWN_EVT| | | +------------------------+----------------+ | |SELF_DOWN_EVT | | | | | | | | +-----------+ +-----------+ | | |NODE_ | |NODE_ | | | +----------|FAILINGOVER|<---------|SYNCHING |-----------+ | | |SELF_ +-----------+ FAILOVER_+-----------+ PEER_ | | | |DOWN_EVT | A BEGIN_EVT A | DOWN_EVT| | | | | | | | | | | | | | | | | | | | |FAILOVER_ |FAILOVER_ |SYNCH_ |SYNCH_ | | | | |END_EVT |BEGIN_EVT |BEGIN_EVT|END_EVT | | | | | | | | | | | | | | | | | | | | | +--------------+ | | | | | +-------->| SELF_UP_ |<-------+ | | | | +-----------------| PEER_UP |----------------+ | | | | |SELF_DOWN_EVT +--------------+ PEER_DOWN_EVT| | | | | | A A | | | | | | | | | | | | | | PEER_UP_EVT| |SELF_UP_EVT | | | | | | | | | | | V V V | | V V V +------------+ +-----------+ +-----------+ +------------+ |SELF_DOWN_ | |SELF_UP_ | |PEER_UP_ | |PEER_DOWN | |PEER_LEAVING| |PEER_COMING| |SELF_COMING| |SELF_LEAVING| +------------+ +-----------+ +-----------+ +------------+ | | A A | | | | | | | | | SELF_ | |SELF_ |PEER_ |PEER_ | | DOWN_EVT| |UP_EVT |UP_EVT |DOWN_EVT | | | | | | | | | | | | | | | +--------------+ | | |PEER_DOWN_EVT +--->| SELF_DOWN_ |<---+ SELF_DOWN_EVT| +------------------->| PEER_DOWN |<--------------------+ +--------------+ Acked-by:

Florian Fainelli says: ==================== net: dsa: misc improvements This patch series builds on top of Andrew's "New DSA bind, switches as devices" patch set and does the following: - add a few helper functions/goodies for net/dsa/dsa2.c to be as close as possible from net/dsa/dsa.c in terms of what drivers can expect, in particular the slave MDIO bus and the enabled_port_mask and phy_mii_mask - fix the CPU port ethtools ops to work in a multiple tree setup since we can no longer assume a single tree is supported - make the bcm_sf2 driver register its own MDIO bus, yet assign it to ds->slave_mii_bus for everything to work in net/dsa/slave.c wrt. PHY probing, this is a tad cleaner than what we have now Changes in v2: Most of the previous patches have been dropped to just keep the relevant ones now. Changes in v3: - split the addition of the slave MII bus as a separate patch - properly unwind all operations at the right place and right time (ethtool ops, slave MDIO bus - fixed a few typos here and there Changes in v4: - removed superfluous dst agrument to dsa_cpu_port_ethtool_{setup,restore} ==================== Signed-off-by:

Register a slave MDIO bus which allows us to divert problematic read/writes towards conflicting pseudo-PHY address (30). Do no longer rely on DSA's slave_mii_bus, but instead provide our own implementation which offers more flexibility as to what to do, and when to register it. We need to register it by the time we are able to get access to our memory mapped registers, which is not until drv->setup() time. In order to avoid forward declarations, we need to re-order the function bodies a bit. Reviewed-by:

We need to move this to be dynamically allocated, and since we can't really be comparing addresses anymore to determine first time initialization versus any other times, just move this to dsa.c and dsa2.c where the remainder of the dst/ds initialization happens.
