The function lio_vf_rep_packet_sent_callback releases the occupation of sc via octeon_free_soft_command. sc should not be used after that. Unfortunately, sc->iq_no is read. To fix this, the patch stores sc->iq_no into a local variable before releasing sc and then uses the local variable instead of sc->iq_no. Signed-off-by:

IP header is not necessarily located right after struct ethhdr, there could be multiple 802.1Q headers in between, this is why we call __vlan_get_protocol().

While introducing the DSA tagging protocol attribute, it was added to the DSA slave network devices, but those actually see untagged traffic (that is their whole purpose). Correct this mistake by putting the tagging sysfs attribute under the DSA master network device where this is the information that we need. While at it, also correct the sysfs documentation mistake that missed the "dsa/" directory component of the attribute.

For flow offload adds, if the rhash insert code fails, the flow will still have been offloaded but the reference to it in the driver freed.

Calling nfp_compile_flow_metadata both assigns a stats context and increments a ref counter on (or allocates) a mask id table entry. These are released by the nfp_modify_flow_metadata call on flow deletion, however, if a flow add fails after metadata is set then the flow entry will be deleted but the metadata assignments leaked. Add an error path to the flow add offload function to ensure allocated metadata is released in the event of an offload fail.

Previously when unbinding a slave the 802.3ad implementation only told partner that the port is not suitable for aggregation by setting the port aggregation state from aggregatable to individual. This is not enough. If the physical layer still stays up and we only unbinded this port from the bond there is nothing in the aggregation status alone to prevent the partner from sending traffic towards us. To ensure that the partner doesn't consider this port at all anymore we should also disable collecting and distributing to signal that this actor is going away. Also clear AD_STATE_SYNCHRONIZATION to ensure partner exits collecting + distributing state. I have tested this behaviour againts Arista EOS switches with mlx5 cards (physical link stays up even when interface is down) and simulated the same situation virtually Linux <-> Linux with two network namespaces running two veth device pairs. In both cases setting aggregation to individual doesn't alone prevent traffic from being to sent towards this port given that the link stays up in partners end. Partner still keeps it's end in collecting + distributing state and continues until timeout is reached. In most cases this means we are losing the traffic partner sends towards our port while we wait for timeout. This is most visible with slow periodic time (LACP rate slow). Other open source implementations like Open VSwitch and libreswitch, and vendor implementations like Arista EOS, seem to disable collecting + distributing to when doing similar port disabling/detaching/removing change. With this patch kernel implementation would behave the same way and ensure partner doesn't consider our actor viable anymore. Signed-off-by:

Setting up and tearing down debugfs is current unbalanced, as seen by this error during resume from suspend: [ 752.134067] dwc-eth-dwmac 2490000.ethernet eth0: ERROR failed to create debugfs directory [ 752.134347] dwc-eth-dwmac 2490000.ethernet eth0: stmmac_hw_setup: failed debugFS registration The imbalance happens because the driver creates the debugfs hierarchy when the device is opened and tears it down when the device is closed. There's little gain in that, and it could be argued that it is even surprising because it's not usually done for other devices. Fix the imbalance by moving the debugfs creation and teardown to the driver's ->probe() and ->remove() implementations instead. Note that the ring descriptors cannot be read while the interface is down, so make sure to return an empty file when the descriptors_status debugfs file is read.

sctp_assoc_update_frag_point() should be called whenever asoc->pathmtu changes, but we missed one place in sctp_association_init(). It would cause frag_point is zero when sending data. As says in Jakub's reproducer, if sp->pathmtu is set by socketopt, the new asoc->pathmtu inherits it in sctp_association_init(). Later when transports are added and their pmtu >= asoc->pathmtu, it will never call sctp_assoc_update_frag_point() to set frag_point. This patch is to fix it by updating frag_point after asoc->pathmtu is set as sp->pathmtu in sctp_association_init(). Note that it moved them after sctp_stream_init(), as stream->si needs to be set first. Frag_point's calculation is also related with datachunk's type, so it needs to update frag_point when stream->si may be changed in sctp_process_init(). v1->v2: - call sctp_assoc_update_frag_point() separately in sctp_process_init and sctp_association_init, per Marcelo's suggestion.

__qdisc_drop_all() accesses skb->prev to get to the tail of the segment-list. With commit 68d2f84a ("net: gro: properly remove skb from list") the skb-list handling has been changed to set skb->next to NULL and set the list-poison on skb->prev. With that change, __qdisc_drop_all() will panic when it tries to dereference skb->prev. Since commit 992cba7e ("net: Add and use skb_list_del_init().") __list_del_entry is used, leaving skb->prev unchanged (thus, pointing to the list-head if it's the first skb of the list). This will make __qdisc_drop_all modify the next-pointer of the list-head and result in a panic later on: [ 34.501053] general protection fault: 0000 [#1] SMP KASAN PTI [ 34.501968] CPU: 2 PID: 0 Comm: swapper/2 Not tainted 4.20.0-rc2.mptcp #108 [ 34.502887] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 0.5.1 01/01/2011 [ 34.504074] RIP: 0010:dev_gro_receive+0x343/0x1f90 [ 34.504751] Code: e0 48 c1 e8 03 42 80 3c 30 00 0f 85 4a 1c 00 00 4d 8b 24 24 4c 39 65 d0 0f 84 0a 04 00 00 49 8d 7c 24 38 48 89 f8 48 c1 e8 03 <42> 0f b6 04 30 84 c0 74 08 3c 04 [ 34.507060] RSP: 0018:ffff8883af507930 EFLAGS: 00010202 [ 34.507761] RAX: 0000000000000007 RBX: ffff8883970b2c80 RCX: 1ffff11072e165a6 [ 34.508640] RDX: 1ffff11075867008 RSI: ffff8883ac338040 RDI: 0000000000000038 [ 34.509493] RBP: ffff8883af5079d0 R08: ffff8883970b2d40 R09: 0000000000000062 [ 34.510346] R10: 0000000000000034 R11: 0000000000000000 R12: 0000000000000000 [ 34.511215] R13: 0000000000000000 R14: dffffc0000000000 R15: ffff8883ac338008 [ 34.512082] FS: 0000000000000000(0000) GS:ffff8883af500000(0000) knlGS:0000000000000000 [ 34.513036] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 34.513741] CR2: 000055ccc3e9d020 CR3: 00000003abf32000 CR4: 00000000000006e0 [ 34.514593] Call Trace: [ 34.514893] <IRQ> [ 34.515157] napi_gro_receive+0x93/0x150 [ 34.515632] receive_buf+0x893/0x3700 [ 34.516094] ? __netif_receive_skb+0x1f/0x1a0 [ 34.516629] ? virtnet_probe+0x1b40/0x1b40 [ 34.517153] ? __stable_node_chain+0x4d0/0x850 [ 34.517684] ? kfree+0x9a/0x180 [ 34.518067] ? __kasan_slab_free+0x171/0x190 [ 34.518582] ? detach_buf+0x1df/0x650 [ 34.519061] ? lapic_next_event+0x5a/0x90 [ 34.519539] ? virtqueue_get_buf_ctx+0x280/0x7f0 [ 34.520093] virtnet_poll+0x2df/0xd60 [ 34.520533] ? receive_buf+0x3700/0x3700 [ 34.521027] ? qdisc_watchdog_schedule_ns+0xd5/0x140 [ 34.521631] ? htb_dequeue+0x1817/0x25f0 [ 34.522107] ? sch_direct_xmit+0x142/0xf30 [ 34.522595] ? virtqueue_napi_schedule+0x26/0x30 [ 34.523155] net_rx_action+0x2f6/0xc50 [ 34.523601] ? napi_complete_done+0x2f0/0x2f0 [ 34.524126] ? kasan_check_read+0x11/0x20 [ 34.524608] ? _raw_spin_lock+0x7d/0xd0 [ 34.525070] ? _raw_spin_lock_bh+0xd0/0xd0 [ 34.525563] ? kvm_guest_apic_eoi_write+0x6b/0x80 [ 34.526130] ? apic_ack_irq+0x9e/0xe0 [ 34.526567] __do_softirq+0x188/0x4b5 [ 34.527015] irq_exit+0x151/0x180 [ 34.527417] do_IRQ+0xdb/0x150 [ 34.527783] common_interrupt+0xf/0xf [ 34.528223] </IRQ> This patch makes sure that skb->prev is set to NULL when entering netem_enqueue.

Sabrina Dubroca says: ==================== fixes for XPS configuration after Symmetric queue selection This fixes some bugs introduced by the "Symmetric queue selection using XPS for Rx queues". First, the refactoring of the cleanup function skipped resetting the queue's NUMA node under some conditions. Second, the accounting on static keys for XPS and RXQS-XPS is unbalanced, so the static key for XPS won't actually disable itself, once enabled. The RXQS-XPS static key can actually be disabled by reconfiguring a device that didn't have RXQS-XPS configured at all. ==================== Signed-off-by: -

Commit 04157469 ("net: Use static_key for XPS maps") introduced a static key for XPS, but the increments/decrements don't match. First, the static key's counter is incremented once for each queue, but only decremented once for a whole batch of queues, leading to large unbalances. Second, the xps_rxqs_needed key is decremented whenever we reset a batch of queues, whether they had any rxqs mapping or not, so that if we setup cpu-XPS on em1 and RXQS-XPS on em2, resetting the queues on em1 would decrement the xps_rxqs_needed key. This reworks the accounting scheme so that the xps_needed key is incremented only once for each type of XPS for all the queues on a device, and the xps_rxqs_needed key is incremented only once for all queues. This is sufficient to let us retrieve queues via get_xps_queue(). This patch introduces a new reset_xps_maps(), which reinitializes and frees the appropriate map (xps_rxqs_map or xps_cpus_map), and drops a reference to the needed keys: - both xps_needed and xps_rxqs_needed, in case of rxqs maps, - only xps_needed, in case of CPU maps. Now, we also need to call reset_xps_maps() at the end of __netif_set_xps_queue() when there's no active map left, for example when writing '00000000,00000000' to all queues' xps_rxqs setting.

The response for a SNMP request can consist of multiple parts, which the cmd callback stages into a kernel buffer until all parts have been received. If the callback detects that the staging buffer provides insufficient space, it bails out with error. This processing is buggy for the first part of the response - while it initially checks for a length of 'data_len', it later copies an additional amount of 'offsetof(struct qeth_snmp_cmd, data)' bytes. Fix the calculation of 'data_len' for the first part of the response. This also nicely cleans up the memcpy code. Fixes: 1da177e4 ("Linux-2.6.12-rc2") Signed-off-by:

From Florian. 8) Memory leak in xt_hashlimit, from Taehee. 9) Call ip_vs_dst_notifier after ipv6_dev_notf, from Xin Long. 10) Fix cttimeout with udplite and gre, from Florian. 11) Preserve oif for IPv6 link-local generated traffic from mangle table, from Alin Nastac. 12) Missing error handling in masquerade notifiers, from Taehee Yoo. 13) Use mutex to protect registration/unregistration of masquerade extensions in order to prevent a race, from Taehee. 14) Incorrect condition check in tree_nodes_free(), also from Taehee. 15) Fix chain counter leak in rule replacement path, from Taehee. ==================== Signed-off-by: -

The net device ndev is freed via free_netdev when failing to register the device. The control flow then jumps to the error handling code block. ndev is used and freed again. Resulting in a use-after-free bug. Signed-off-by:

Add the two 1000BaseLX enum values to the X550's check for 1Gbps modules, allowing the core driver code to establish a link over this SFP type. This is done by the out-of-tree driver but the fix wasn't in mainline.

In __i40e_del_filter function, the flag __I40E_MACVLAN_SYNC_PENDING for the PF state is wrongly set for the VSI. Deleting any of the MAC filters has caused the incorrect syncing for the PF. Fix it by setting this state flag to the intended PF. CC: stable <stable@vger.kernel.org> Signed-off-by:
