There is one e1e_wphy() call in e1000_set_d0_lplu_state_82571 that we have caught its return value but lack further handling. Check and terminate the execution flow just like other e1e_wphy() in this function. Fixes: bc7f75fa ("[E1000E]: New pci-express e1000 driver (currently for ICH9 devices only)") Signed-off-by:

A possible race condition was found in e1000_reset_task, after discovering a similar issue in igb driver via commit 024a8168 ("igb: reinit_locked() should be called with rtnl_lock"). Added rtnl_lock() and rtnl_unlock() to avoid this. Fixes: bc7f75fa ("[E1000E]: New pci-express e1000 driver (currently for ICH9 devices only)") Suggested-by:

The comment describing the timestamps layout in the packet buffer is wrong and the code is actually retrieving the timestamp in Timer 1 reference instead of Timer 0. This hasn't been a big issue so far because hardware is configured to report both timestamps using Timer 0 (see IGC_SRRCTL register configuration in igc_ptp_enable_rx_timestamp() helper). This patch fixes the comment and the code so we retrieve the timestamp in Timer 0 reference as expected. This patch also takes the opportunity to get rid of the hw.mac.type check since it is not required. Fixes: 81b05520 ("igc: Add support for RX timestamping") Signed-off-by:

Similar to commit 92696286 ("net: bcmgenet: Set phydev->dev_flags only for internal PHYs") we need to qualify the phydev->dev_flags based on whether the port is connected to an internal or external PHY otherwise we risk having a flags collision with a completely different interpretation depending on the driver.

The bcm_sf2 driver uses the b53 driver as a library but does not make usre of the b53_setup() function, this made it fail to inherit the vlan_filtering_is_global attribute. Fix this by moving the assignment to b53_switch_alloc() which is used by bcm_sf2. Fixes: 7228b23e ("net: dsa: b53: Let DSA handle mismatched VLAN filtering settings") Signed-off-by:

pxa168_eth_remove() firstly calls unregister_netdev(), then cancels a timeout work. unregister_netdev() shuts down a device interface and removes it from the kernel tables. If the timeout occurs in parallel, the timeout work (pxa168_eth_tx_timeout_task) performs stop and open of the device. It may lead to an inconsistent state and memory leaks.

In the rare case that drop_monitor fails to register its probe on the 'napi_poll' tracepoint, it will not deactivate its hysteresis timer as part of the error path. If the hysteresis timer was armed by the shortly lived 'kfree_skb' probe and user space retries to initiate tracing, a warning will be emitted for trying to initialize an active object [1]. Fix this by properly undoing all the operations that were done prior to probe registration, in both software and hardware code paths. Note that syzkaller managed to fail probe registration by injecting a slab allocation failure [2].

Syzbot reported the suspecious RCU usage in nexthop_fib6_nh() when called from ipv6_route_seq_show(). The reason is ipv6_route_seq_start() calls rcu_read_lock_bh(), while nexthop_fib6_nh() calls rcu_dereference_rtnl(). The fix proposed is to add a variant of nexthop_fib6_nh() to use rcu_dereference_bh_rtnl() for ipv6_route_seq_show().

Daniel Borkmann says: ==================== Fix ip6ip6 crash for collect_md skbs Fix a NULL pointer deref panic I ran into for regular ip6ip6 tunnel devices when collect_md populated skbs were redirected to them for xmit. See patches for further details, thanks! ==================== Signed-off-by: -
Daniel Borkmann authored
I ran into a crash where setting up a ip6ip6 tunnel device which was /not/ set to collect_md mode was receiving collect_md populated skbs for xmit. The BPF prog was populating the skb via bpf_skb_set_tunnel_key() which is assigning special metadata dst entry and then redirecting the skb to the device, taking ip6_tnl_start_xmit() -> ipxip6_tnl_xmit() -> ip6_tnl_xmit() and in the latter it performs a neigh lookup based on skb_dst(skb) where we trigger a NULL pointer dereference on dst->ops->neigh_lookup() since the md_dst_ops do not populate neigh_lookup callback with a fake handler. Transform the md_dst_ops into generic dst_blackhole_ops that can also be reused elsewhere when needed, and use them for the metadata dst entries as callback ops. Also, remove the dst_md_discard{,_out}() ops and rely on dst_discard{,_out}() from dst_init() which free the skb the same way modulo the splat. Given we will be able to recover just fine from there, avoid any potential splats iff this gets ever triggered in future (or worse, panic on warns when set).

Move generic blackhole dst ops to the core and use them from both ipv4_dst_blackhole_ops and ip6_dst_blackhole_ops where possible. No functional change otherwise. We need these also in other locations and having to define them over and over again is not great. Signed-off-by:

1. Don't set the ts_format bit to default when it reserved - device is running in the old mode (free running). 2. XRC doesn't have a CQ therefore the ts format in the QP context should be default / free running. 3. Set ts_format to WQ.

VF tunnel TX traffic offload is adding flow which forward to flow tables with lower level, which isn't support on all FW versions and may cause firmware to fail with syndrome.

flow_attr->ip_version has the matching that should be done inner/outer. When working with chains, decapsulation is done on chain0 and next chain match on outer header which is the original inner which could be ipv4. So in tunnel route resolution we cannot use that to know which ip version we are at so save tun_ip_version when parsing the tunnel match and use that.

The cited change added offload support for Geneve options without verifying the validity of the options masks, this caused offload of rules with match on Geneve options with class,type and data masks which are zero to fail.

Port timestamping for PTP can be enabled/disabled while the channels are closed. In that case mlx5e_safe_switch_channels is skipped, and the preactivate hook is called directly. However, if that hook returns an error, the channel parameters must be reverted back to their old values. This commit adds missing handling on this case.

Each RQ (including XSK RQs) takes a reference to the XDP program. When an XDP program is attached or detached, the channels and queues are recreated, however, there is a special flow for changing an active XDP program to another one. In that flow, channels and queues stay alive, but the refcounts of the old and new XDP programs are adjusted. This flow didn't increment refcount by the number of active XSK RQs, and this commit fixes it. Fixes: db05815b ("net/mlx5e: Add XSK zero-copy support") Signed-off-by:

Since cited patch, MLX5E_REQUIRED_WQE_MTTS is not a power of two. Hence, usage of MLX5E_LOG_ALIGNED_MPWQE_PPW should be replaced, as it lost some accuracy.
