The current implementation does not handle timeout in case of command with callback request, and this can lead to deadlock if the command doesn't get fw response. Add delayed callback timeout work before posting the command to fw. In case of real fw command completion we will cancel the delayed work. In case of fw command timeout the callback timeout handler will be called and it will simulate fw completion with timeout error.

The device ID for VFs is in a different location than PFs. This results in the poll always timing out for VFs. There's no good way to read the VF device ID without using the PF's configuration space. Switch to waiting for the health poll to start incrementing. Also remove the 1s sleep at the beginning. fixes: 89d44f0a ('net/mlx5_core: Add pci error handlers to mlx5_core driver') Signed-off-by:

In internal error state the health poll thread will eventually call synchronize_irq() (to safely trigger command completions) which might sleep, so we are calling sleeping function from atomic context which is invalid. Here we move trigger_cmd_completions(dev) to enter error state which is the earliest stage in error state handling. This way we won't need to wait for next health poll to trigger command completions and will solve the scheduling while atomic issue. mlx5_enter_error_state can be called from two contexts, protect it with dev->intf_state_lock Fixes: 89d44f0a ('net/mlx5_core: Add pci error handlers to mlx5_core driver') Signed-off-by:

In case of internal error state we will simulate the commands status through the return value translation function, but we need to simulate all the teardown fw commands as successful so we will not have fw command failure prints.

ether_addr_equal_64bits() requires some care about its arguments, namely that 8 bytes might be read, even if last 2 byte values are not used. KASan detected a violation with null_mac_addr and lacpdu_mcast_addr in bond_3ad.c Same problem with mac_bcast[] and mac_v6_allmcast[] in bond_alb.c : Although the 8-byte alignment was there, KASan would detect out of bound accesses.

ip_skb_dst_mtu uses skb->sk, assuming it is an AF_INET socket (e.g. it calls ip_sk_use_pmtu which casts sk as an inet_sk). However, in the case of UDP tunneling, the skb->sk is not necessarily an inet socket (could be AF_PACKET socket, or AF_UNSPEC if arriving from tun/tap). OTOH, the sk passed as an argument throughout IP stack's output path is the one which is of PMTU interest: - In case of local sockets, sk is same as skb->sk; - In case of a udp tunnel, sk is the tunneling socket. Fix, by passing ip_finish_output's sk to ip_skb_dst_mtu. This augments 7026b1dd 'netfilter: Pass socket pointer down through okfn().' Signed-off-by:

Now ixgbevf_write/read_posted_mbx use -IXGBE_ERR_MBX as the initiative return value, but it's incorrect, cause in ixgbevf_vlan_rx_add_vid(), it use err == IXGBE_ERR_MBX, the err returned from mac.ops.set_vfta, and in ixgbevf_set_vfta_vf, it return from write/read_posted. so we should initialize err with IXGBE_ERR_MBX, instead of -IXGBE_ERR_MBX. With this fix, the other functions that called it also can work well, cause they only care about if err is 0 or not. Signed-off-by:

Only the first and last netlink message for a particular conntrack are actually sent. The first message is sent through nf_conntrack_confirm when the conntrack is committed. The last one is sent when the conntrack is destroyed on timeout. The other conntrack state change messages are not advertised. When the conntrack subsystem is used from netfilter, nf_conntrack_confirm is called for each packet, from the postrouting hook, which in turn calls nf_ct_deliver_cached_events to send the state change netlink messages. This commit fixes the problem by calling nf_ct_deliver_cached_events in the non-commit case as well.

neigh_xmit() expects to be called inside an RCU-bh read side critical section, and while one of its two current callers gets this right, the other one doesn't. More specifically, neigh_xmit() has two callers, mpls_forward() and mpls_output(), and while both callers call neigh_xmit() under rcu_read_lock(), this provides sufficient protection for neigh_xmit() only in the case of mpls_forward(), as that is always called from softirq context and therefore doesn't need explicit BH protection, while mpls_output() can be called from process context with softirqs enabled. When mpls_output() is called from process context, with softirqs enabled, we can be preempted by a softirq at any time, and RCU-bh considers the completion of a softirq as signaling the end of any pending read-side critical sections, so if we do get a softirq while we are in the part of neigh_xmit() that expects to be run inside an RCU-bh read side critical section, we can end up with an unexpected RCU grace period running right in the middle of that critical section, making things go boom. This patch fixes this impedance mismatch in the callee, by making neigh_xmit() always take rcu_read_{,un}lock_bh() around the code that expects to be treated as an RCU-bh read side critical section, as this seems a safer option than fixing it in the callers.

I've got a bug report about an e1000e interface, where a VLAN interface is set up on top of it: $ ip link add link ens1f0 name ens1f0.99 type vlan id 99 $ ip link set ens1f0 up $ ip link set ens1f0.99 up $ ip addr add 192.168.99.92 dev ens1f0.99 At this point, I can ping another host on vlan 99, ip 192.168.99.91. However, if I do the following: $ ethtool -K ens1f0 rxvlan off Then no traffic passes on ens1f0.99. It comes back if I toggle rxvlan on again. I'm not sure if this is actually intended behavior, or if there's a lack of software VLAN stripping fallback, or what, but things continue to work if I simply don't call e1000e_vlan_strip_disable() if there are active VLANs (plagiarizing a function from the e1000 driver here) on the interface. Also slipped a related-ish fix to the kerneldoc text for e1000e_vlan_strip_disable here... Signed-off-by:

The resulting LLC frame header has a too large PDU length, causing the llc_fixup_skb() function of net/llc/llc_input.c to reject the incoming skb, effectively breaking STP. Solve the problem by properly substracting the IEEE 802.11 frame header size from the PDU length, allowing the LLC processor to pick up the incoming control messages. Special thanks to Gerry Rozema for tracking down the regression and proposing a suitable patch.

There is a static checker warning here "warn: mask and shift to zero" and the code sets "ring" to zero every time. From looking at how QLCNIC_FETCH_RING_ID() is used in qlcnic_83xx_process_rcv_ring() the qlcnic_83xx_hndl() should be removed. Fixes: 4be41e92 ('qlcnic: 83xx data path routines') Signed-off-by:

Commit dead9f29 ("perf: Fix race in BPF program unregister") moved destruction of BPF program from free_event_rcu() callback to __free_event(), which is problematic if used with tail calls: if prog A is attached as trace event directly, but at the same time present in a tail call map used by another trace event program elsewhere, then we need to delay destruction via RCU grace period since it can still be in use by the program doing the tail call (the prog first needs to be dropped from the tail call map, then trace event with prog A attached destroyed, so we get immediate destruction).

I made a dumb off-by-one mistake when I added the vlan stats counter dumping code. The increment should happen before the check, not after otherwise we miss one entry when we continue dumping. Fixes: a60c0903 ("bridge: netlink: export per-vlan stats") Signed-off-by:

Arjun reported a bug in TCP stack and bisected it to a recent commit. In case where we process SACK, we can coalesce multiple skbs into fat ones (tcp_shift_skb_data()), to lower write queue overhead, because we do not expect to retransmit these packets. However, SACK reneging can happen, forcing the sender to retransmit all these packets. If skb->len is above 64KB, we then send buggy IP packets that could hang TSO engine on cxgb4. Neal suggested to use tcp_tso_autosize() instead of tp->gso_segs so that we cook packets of optimal size vs TCP/pacing. Thanks to Arjun for reporting the bug and running the tests !

Check for SMU RX local/remote faults along with SPU LINK status. Otherwise at times link is UP at our end but DOWN at link partner's side. Also due to an issue in BGX it's rarely seen that initialization doesn't happen properly and SMU RX reports faults with everything fine at SPU. This patch tries to reinitialize LMAC to fix it. Also fixed LMAC disable sequence to properly bring down link. Signed-off-by:
