| Pull networking fixes from David Miller: 1) Several nf_flow_table_offload fixes from Pablo Neira Ayuso, including adding a missing ipv6 match description. 2) Several heap overflow fixes in mwifiex from qize wang and Ganapathi Bhat. 3) Fix uninit value in bond_neigh_init(), from Eric Dumazet. 4) Fix non-ACPI probing of nxp-nci, from Stephan Gerhold. 5) Fix use after free in tipc_disc_rcv(), from Tuong Lien. 6) Enforce limit of 33 tail calls in mips and riscv JIT, from Paul Chaignon. 7) Multicast MAC limit test is off by one in qede, from Manish Chopra. 8) Fix established socket lookup race when socket goes from TCP_ESTABLISHED to TCP_LISTEN, because there lacks an intervening RCU grace period. From Eric Dumazet. 9) Don't send empty SKBs from tcp_write_xmit(), also from Eric Dumazet. 10) Fix active backup transition after link failure in bonding, from Mahesh Bandewar. 11) Avoid zero sized hash table in gtp driver, from Taehee Yoo. 12) Fix wrong interface passed to ->mac_link_up(), from Russell King. 13) Fix DSA egress flooding settings in b53, from Florian Fainelli. 14) Memory leak in gmac_setup_txqs(), from Navid Emamdoost. 15) Fix double free in dpaa2-ptp code, from Ioana Ciornei. 16) Reject invalid MTU values in stmmac, from Jose Abreu. 17) Fix refcount leak in error path of u32 classifier, from Davide Caratti. 18) Fix regression causing iwlwifi firmware crashes on boot, from Anders Kaseorg. 19) Fix inverted return value logic in llc2 code, from Chan Shu Tak. 20) Disable hardware GRO when XDP is attached to qede, frm Manish Chopra. 21) Since we encode state in the low pointer bits, dst metrics must be at least 4 byte aligned, which is not necessarily true on m68k. Add annotations to fix this, from Geert Uytterhoeven. * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (160 commits) sfc: Include XDP packet headroom in buffer step size. sfc: fix channel allocation with brute force net: dst: Force 4-byte alignment of dst_metrics selftests: pmtu: fix init mtu value in description hv_netvsc: Fix unwanted rx_table reset net: phy: ensure that phy IDs are correctly typed mod_devicetable: fix PHY module format qede: Disable hardware gro when xdp prog is installed net: ena: fix issues in setting interrupt moderation params in ethtool net: ena: fix default tx interrupt moderation interval net/smc: unregister ib devices in reboot_event net: stmmac: platform: Fix MDIO init for platforms without PHY llc2: Fix return statement of llc_stat_ev_rx_null_dsap_xid_c (and _test_c) net: hisilicon: Fix a BUG trigered by wrong bytes_compl net: dsa: ksz: use common define for tag len s390/qeth: don't return -ENOTSUPP to userspace s390/qeth: fix promiscuous mode after reset s390/qeth: handle error due to unsupported transport mode cxgb4: fix refcount init for TC-MQPRIO offload tc-testing: initial tdc selftests for cls_u32 ... | |||
| 2019-12-19 | net/sched: cls_u32: fix refcount leak in the error path of u32_change() | Davide Caratti | |
| when users replace cls_u32 filters with new ones having wrong parameters, so that u32_change() fails to validate them, the kernel doesn't roll-back correctly, and leaves semi-configured rules. Fix this in u32_walk(), avoiding a call to the walker function on filters that don't have a match rule connected. The side effect is, these "empty" filters are not even dumped when present; but that shouldn't be a problem as long as we are restoring the original behaviour, where semi-configured filters were not even added in the error path of u32_change().

| 2019-12-18 | net: sch_ets: Add a new Qdisc | Petr Machata | |
| Introduces a new Qdisc, which is based on 802.1Q-2014 wording. It is PRIO-like in how it is configured, meaning one needs to specify how many bands there are, how many are strict and how many are dwrr, quanta for the latter, and priomap. The new Qdisc operates like the PRIO / DRR combo would when configured as per the standard. The strict classes, if any, are tried for traffic first. When there's no traffic in any of the strict queues, the ETS ones (if any) are treated in the same way as in DRR.

| 2019-12-18 | sch_cake: drop unused variable tin_quantum_prio | Kevin 'ldir' Darbyshire-Bryant | |
| Turns out tin_quantum_prio isn't used anymore and is a leftover from a previous implementation of diffserv tins. Since the variable isn't used in any calculations it can be eliminated. Drop variable and places where it was set. Rename remaining variable and consolidate naming of intermediate variables that set it.

| 2019-12-06 | net: sched: allow indirect blocks to bind to clsact in TC | John Hurley | |
| When a device is bound to a clsact qdisc, bind events are triggered to registered drivers for both ingress and egress. However, if a driver registers to such a device using the indirect block routines then it is assumed that it is only interested in ingress offload and so only replays ingress bind/unbind messages. The NFP driver supports the offload of some egress filters when registering to a block with qdisc of type clsact. However, on unregister, if the block is still active, it will not receive an unbind egress notification which can prevent proper cleanup of other registered callbacks. Modify the indirect block callback command in TC to send messages of ingress and/or egress bind depending on the qdisc in use. NFP currently supports egress offload for TC flower offload so the changes are only added to TC.

| 2019-12-06 | net: core: rename indirect block ingress cb function | John Hurley | |
| With indirect blocks, a driver can register for callbacks from a device that is does not 'own', for example, a tunnel device. When registering to or unregistering from a new device, a callback is triggered to generate a bind/unbind event. This, in turn, allows the driver to receive any existing rules or to properly clean up installed rules. When first added, it was assumed that all indirect block registrations would be for ingress offloads. However, the NFP driver can, in some instances, support clsact qdisc binds for egress offload. Change the name of the indirect block callback command in flow_offload to remove the 'ingress' identifier from it. While this does not change functionality, a follow up patch will implement a more more generic callback than just those currently just supporting ingress offload.

| When user runs a command like tc qdisc add dev eth1 root mqprio KASAN stack-out-of-bounds warning is emitted. Currently, NLA_ALIGN macro used in mqprio_dump provides too large buffer size as argument for nla_put and memcpy down the call stack. The flow looks like this: 1. nla_put expects exact object size as an argument; 2. Later it provides this size to memcpy; 3. To calculate correct padding for SKB, nla_put applies NLA_ALIGN macro itself. Therefore, NLA_ALIGN should not be applied to the nla_put parameter. Otherwise it will lead to out-of-bounds memory access in memcpy.

Netfilter can support this because it runs through the NAT table twice - once on ingress and again after egress. The act_ct action doesn't have such capability. Like netfilter hook infrastructure, we should run through NAT twice to keep the symmetry.

| 2019-12-03 | cls_flower: Fix the behavior using port ranges with hw-offload | Yoshiki Komachi | |
| The recent commit 5c72299fba9d ("net: sched: cls_flower: Classify packets using port ranges") had added filtering based on port ranges to tc flower. However the commit missed necessary changes in hw-offload code, so the feature gave rise to generating incorrect offloaded flow keys in NIC. One more detailed example is below: $ tc qdisc add dev eth0 ingress $ tc filter add dev eth0 ingress protocol ip flower ip_proto tcp \ dst_port 100-200 action drop With the setup above, an exact match filter with dst_port == 0 will be installed in NIC by hw-offload. IOW, the NIC will have a rule which is equivalent to the following one. $ tc qdisc add dev eth0 ingress $ tc filter add dev eth0 ingress protocol ip flower ip_proto tcp \ dst_port 0 action drop The behavior was caused by the flow dissector which extracts packet data into the flow key in the tc flower. More specifically, regardless of exact match or specified port ranges, fl_init_dissector() set the FLOW_DISSECTOR_KEY_PORTS flag in struct flow_dissector to extract port numbers from skb in skb_flow_dissect() called by fl_classify(). Note that device drivers received the same struct flow_dissector object as used in skb_flow_dissect(). Thus, offloaded drivers could not identify which of these is used because the FLOW_DISSECTOR_KEY_PORTS flag was set to struct flow_dissector in either case. This patch adds the new FLOW_DISSECTOR_KEY_PORTS_RANGE flag and the new tp_range field in struct fl_flow_key to recognize which filters are applied to offloaded drivers. At this point, when filters based on port ranges passed to drivers, drivers return the EOPNOTSUPP error because they do not support the feature (the newly created FLOW_DISSECTOR_KEY_PORTS_RANGE flag).

In case if mqprio settings are provided next time the error is returned as it's not allowed to change traffic class mapping in-flignt and that is normal. But if configuration is absolutely the same - no need to return error. It allows to provide same command couple times, changing only base time for instance, or changing only scheds maps, but leaving mqprio setting w/o modification. It more corresponds the message: "Changing the traffic mapping of a running schedule is not supported", so reject mqprio if it's really changed.

| 2019-11-05 | net: sched: prevent duplicate flower rules from tcf_proto destroy race | John Hurley | |
| When a new filter is added to cls_api, the function tcf_chain_tp_insert_unique() looks up the protocol/priority/chain to determine if the tcf_proto is duplicated in the chain's hashtable. It then creates a new entry or continues with an existing one. In cls_flower, this allows the function fl_ht_insert_unque to determine if a filter is a duplicate and reject appropriately, meaning that the duplicate will not be passed to drivers via the offload hooks. However, when a tcf_proto is destroyed it is removed from its chain before a hardware remove hook is hit. This can lead to a race whereby the driver has not received the remove message but duplicate flows can be accepted. This, in turn, can lead to the offload driver receiving incorrect duplicate flows and out of order add/delete messages. Prevent duplicates by utilising an approach suggested by Vlad Buslov. A hash table per block stores each unique chain/protocol/prio being destroyed. This entry is only removed when the full destroy (and hardware offload) has completed. If a new flow is being added with the same identiers as a tc_proto being detroyed, then the add request is replayed until the destroy is complete.

Thus if call qdisc show it can crash. Farther, next second time, when sched list is updated, the admin_sched is not NULL and becomes the oper_sched, previous oper_sched was NULL so just skipped. But then admin_sched is assigned new_admin, but schedules to free previous assigned admin_sched (that already became oper_sched). Farther, next third time, when sched list is updated, while one more swap, oper_sched is not null, but it was happy to be freed already (while prev. admin update), so while try to free oper_sched the kernel panic happens at taprio_free_sched_cb(). So, move the "swap emulation" where it should be according to function comment from code.

| 2019-10-30 | net: sched: update action implementations to support flags | Vlad Buslov | |
| Extend struct tc_action with new "tcfa_flags" field. Set the field in tcf_idr_create() function and provide new helper tcf_idr_create_from_flags() that derives 'cpustats' boolean from flags value. Update individual hardware-offloaded actions init() to pass their "flags" argument to new helper in order to skip percpu stats allocation when user requested it through flags.

If regular non-percpu allocated counters are in use, then obtain action tcfa_lock while modifying them.

| 2019-10-30 | net: sched: don't expose action qstats to skb_tc_reinsert() | Vlad Buslov | |
| Previous commit introduced helper function for updating qstats and refactored set of actions to use the helpers, instead of modifying qstats directly. However, one of the affected action exposes its qstats to skb_tc_reinsert(), which then modifies it. Refactor skb_tc_reinsert() to return integer error code and don't increment overlimit qstats in case of error, and use the returned error code in tcf_mirred_act() to manually increment the overlimit counter with new helper function.

| Currently, all implementations of tc_action_ops->stats_update() callback have almost exactly the same implementation of counters update code (besides gact which also updates drop counter).
