When adding a point to point downlink to the bond, we neglected to reset the bond's flags, which were still using flags like BROADCAST and MULTICAST. Consequently, this would initiate ARP/DAD for P2P downlink interfaces, such as when adding a GRE device to the bonding. To address this issue, let's reset the bond's flags for P2P interfaces.

Fix ethtool FDIR logic to not use memory after its release. In the ice_ethtool_fdir.c file there are 2 spots where code can refer to pointers which may be missing. In the ice_cfg_fdir_xtrct_seq() function seg may be freed but even then may be still used by memcpy(&tun_seg[1], seg, sizeof(*seg)). In the ice_add_fdir_ethtool() function struct ice_fdir_fltr *input may first fail to be added via ice_fdir_update_list_entry() but then may be deleted by ice_fdir_update_list_entry. Terminate in both cases when the returned value of the previous operation is other than 0, free memory and don't use it anymore. Reported-by:

For both IPv4 and IPv6 incoming TCP connections are tracked in a hash table with a hash over the source & destination addresses and ports. However, the IPv6 hash is insufficient and can lead to a high rate of collisions. The IPv6 hash used an XOR to fit everything into the 96 bits for the fast jenkins hash, meaning it is possible for an external entity to ensure the hash collides, thus falling back to a linear search in the bucket, which is slow. We take the approach of hash the full length of IPv6 address in __ipv6_addr_jhash() so that all users can benefit from a more secure version. While this may look like it adds overhead, the reality of modern CPUs means that this is unmeasurable in real world scenarios. In simulating with llvm-mca, the increase in cycles for the hashing code was ~16 cycles on Skylake (from a base of ~155), and an extra ~9 on Nehalem (base of ~173). In commit dd6d2910 ("netfilter: conntrack: switch to siphash") netfilter switched from a jenkins hash to a siphash, but even the faster hsiphash is a more significant overhead (~20-30%) in some preliminary testing. So, in this patch, we keep to the more conservative approach to ensure we don't add much overhead per SYN. In testing, this results in a consistently even spread across the connection buckets. In both testing and real-world scenarios, we have not found any measurable performance impact. Fixes: 08dcdbf6 ("ipv6: use a stronger hash for tcp") Signed-off-by:

According to the implementation of XDP of FEC driver, the XDP path shares the transmit queues with the kernel network stack, so it is possible to lead to a tx timeout event when XDP uses the tx queue pretty much exclusively. And this event will cause the reset of the FEC hardware. To avoid timeout in this case, we use the txq_trans_cond_update() interface to update txq->trans_start to jiffies so that watchdog won't generate a transmit timeout warning.

In VXLAN-GPE, there may not be an Ethernet header following the VXLAN header. But in GRO, the vxlan driver calls eth_gro_receive unconditionally, which means the following header is incorrectly parsed as Ethernet. Introduce GPE specific GRO handling. For better performance, do not check for GPE during GRO but rather install a different set of functions at setup time. Fixes: e1e5314d ("vxlan: implement GPE") Reported-by:

The vxlan_parse_gpe_hdr function extracts the next protocol value from the GPE header and marks GPE bits as parsed. In order to be used in the next patch, split the function into protocol extraction and bit marking. The bit marking is meaningful only in vxlan_rcv; move it directly there. Rename the function to vxlan_parse_gpe_proto to reflect what it now does. Remove unused arguments skb and vxflags. Move the function earlier in the file to allow it to be called from more places in the next patch. Signed-off-by:

VXLAN-GPE does not add an extra inner Ethernet header. Take that into account when calculating header length. This causes problems in skb_tunnel_check_pmtu, where incorrect PMTU is cached. In the collect_md mode (which is the only mode that VXLAN-GPE supports), there's no magic auto-setting of the tunnel interface MTU. It can't be, since the destination and thus the underlying interface may be different for each packet. So, the administrator is responsible for setting the correct tunnel interface MTU. Apparently, the administrators are capable enough to calculate that the maximum MTU for VXLAN-GPE is (their_lower_MTU - 36). They set the tunnel interface MTU to 1464. If you run a TCP stream over such interface, it's then segmented according to the MTU 1464, i.e. producing 1514 bytes frames. Which is okay, this still fits the lower MTU. However, skb_tunnel_check_pmtu (called from vxlan_xmit_one) uses 50 as the header size and thus incorrectly calculates the frame size to be 1528. This leads to ICMP too big message being generated (locally), PMTU of 1450 to be cached and the TCP stream to be resegmented. The fix is to use the correct actual header size, especially for skb_tunnel_check_pmtu calculation. Fixes: e1e5314d ("vxlan: implement GPE") Signed-off-by:

In iavf_adminq_task(), if the function can't acquire the adapter->crit_lock, it checks if the driver is removing. If so, it simply exits without re-enabling the interrupt. This is done to ensure that the task stops processing as soon as possible once the driver is being removed. However, if the IAVF_FLAG_PF_COMMS_FAILED is set, the function checks this before attempting to acquire the lock. In this case, the function exits early and re-enables the interrupt. This will happen even if the driver is already removing. Avoid this, by moving the check to after the adapter->crit_lock is acquired. This way, if the driver is removing, we will not re-enable the interrupt. Fixes: fc2e6b3b ("iavf: Rework mutexes for better synchronisation") Signed-off-by:
