Currently in ice_vsi_get_qs() we set the mapping_mode for Tx and Rx to vsi->[tx|rx]_mapping_mode, but the problem is vsi->[tx|rx]_mapping_mode have not been set yet. This was working because ICE_VSI_MAP_CONTIG is defined to 0. Fix this by being explicit with our mapping mode by initializing the Tx and Rx structure's mapping_mode to ICE_VSI_MAP_CONTIG and then setting the vsi->[tx|rx]_mapping_mode to the [tx|rx]_qs_cfg.mapping_mode values. Also, only assign the vsi->[tx|rx]_mapping_mode when the queues are successfully mapped to the VSI. With this change there was no longer a need to initialize the ret variable to 0 so remove that.

Currently when we enable/disable all Rx queues we do the following sequence for each Rx queue and then move to the next queue. 1. Enable/Disable the Rx queue via register write. 2. Read the configuration register to determine if the Rx queue was enabled/disabled successfully. In some cases enabling/disabling queue 0 fails because of step 2 above. Fix this by doing step 1 for all of the Rx queues and then step 2 for all of the Rx queues. Also, there are cases where we enable/disable a single queue (i.e. SR-IOV and XDP) so add a new function that does step 1 and 2 above with a read flush in between. This change also required a single Rx queue to be enabled/disabled with and without waiting for the change to propagate through hardware. Fix this by adding a boolean wait flag to the necessary functions. Also, add the keywords "one" and "all" to distinguish between enabling/disabling a single Rx queue and all Rx queues respectively.

Currently the VF can see other's broadcast and multicast traffic because it always has a VLAN filter for VLAN 0. Fix this by removing/adding the VF's VLAN 0 filter when a port VLAN is added/removed respectively. This required a few changes. 1. Move where we add VLAN 0 by default for the VF into ice_alloc_vsi_res() because this is when we determine if a port VLAN is present for load and reset. 2. Moved where we kill the old port VLAN filter in ice_set_vf_port_vlan() to the very end of the function because it allows us to save the old port VLAN configuration upon any failure case. 3. During adding/removing of a port VLAN via ice_set_vf_port_vlan() we also need to remove/add the VLAN 0 filter rule respectively. 4. Improve log messages.

Currently when configuring a port VLAN for a VF we are only shifting the QoS bits by 12. This is incorrect. Fix this by getting rid of the ICE specific VLAN defines and use the kernel VLAN defines instead. Also, don't assign a value to vlanprio until the VLAN ID and QoS parameters have been validated. Also, there are many places we do (le16_to_cpu(vsi->info.pvid) & VLAN_VID_MASK). Instead do (vf->port_vlan_info & VLAN_VID_MASK) because we always save what's stored in vsi->info.pvid to vf->port_vlan_info in the CPU's endianness.

Currently ice_vsi_manage_pvid() calls ice_vsi_[set|kill]_pvid_fill_ctxt() when enabling/disabling a port VLAN on a VSI respectively. These two functions have some duplication so just move their unique pieces inline in ice_vsi_manage_pvid() and then the duplicate code can be reused for both the enabling/disabling paths. Before this patch the info.pvid field was not being written correctly via ice_vsi_kill_pvid_fill_ctxt() so it was being hard coded to 0 in ice_set_vf_port_vlan(). Fix this by setting the info.pvid field to 0 before calling ice_vsi_update() in ice_vsi_manage_pvid(). We currently use vf->port_vlan_id to keep track of the port VLAN ID and QoS, which is a bit misleading. Fix this by renaming it to vf->port_vlan_info. Also change the name of the argument for ice_vsi_manage_pvid() from vid to pvid_info. In ice_vsi_manage_pvid() only save the fields that were modified in the VSI properties structure on success instead of the entire thing.

Allow support for S-Tag + C-Tag VLAN traffic by disabling pruning when there are no 0x8100 VLAN interfaces currently created on top of the PF. When an 0x8100 VLAN interface is configured, enable pruning and only support single and double C-Tag VLAN traffic. If all of the 0x8100 interfaces that were created on top of the PF are removed via ethtool -K <iface> rx-vlan-filter off or via ip tools, then disable pruning and allow S-Tag + C-Tag traffic again. Add VLAN 0 filter by default for the PF. This is because a bridge sets the default_pvid to 1, sends the request down to ice_vlan_rx_add_vid(), and we never get the request to add VLAN 0 via the 8021q module which causes all untagged traffic to be dropped.

Jason A. Donenfeld says: ==================== icmp: account for NAT when sending icmps from ndo layer The ICMP routines use the source address for two reasons: 1. Rate-limiting ICMP transmissions based on source address, so that one source address cannot provoke a flood of replies. If the source address is wrong, the rate limiting will be incorrectly applied. 2. Choosing the interface and hence new source address of the generated ICMP packet. If the original packet source address is wrong, ICMP replies will be sent from the wrong source address, resulting in either a misdelivery, infoleak, or just general network admin confusion. Most of the time, the icmp_send and icmpv6_send routines can just reach down into the skb's IP header to determine the saddr. However, if icmp_send or icmpv6_send is being called from a network device driver -- there are a few in the tree -- then it's possible that by the time icmp_send or icmpv6_send looks at the packet, the packet's source address has already been transformed by SNAT or MASQUERADE or some other transformation that CONNTRACK knows about. In this case, the packet's source address is most certainly the *wrong* source address to be used for the purpose of ICMP replies. Rather, the source address we want to use for ICMP replies is the original one, from before the transformation occurred. Fortunately, it's very easy to just ask CONNTRACK if it knows about this packet, and if so, how to fix it up. The saddr is the only field in the header we need to fix up, for the purposes of the subsequent processing in the icmp_send and icmpv6_send functions, so we do the lookup very early on, so that the rest of the ICMP machinery can progress as usual. Changes v3->v4: - Add back the skb_shared checking, since the previous assumption isn't actually true [Eric]. This implies dropping the additional patches v3 had for removing skb_share_check from various drivers. We can revisit that general set of ideas later, but that's probably better suited as a net-next patchset rather than this stable one which is geared at fixing bugs. So, this implements things in the safe conservative way. Changes v2->v3: - Add selftest to ensure this actually does what we want and never regresses. - Check the size of the skb header before operating on it. - Use skb_ensure_writable to ensure we can modify the cloned skb [Florian]. - Conditionalize this on IPS_SRC_NAT so we don't do anything unnecessarily [Florian]. - It turns out that since we're calling these from the xmit path, skb_share_check isn't required, so remove that [Florian]. This simplifes the code a bit too. **The supposition here is that skbs passed to ndo_start_xmit are _never_ shared. If this is not correct NOW IS THE TIME TO PIPE UP, for doom awaits us later.** - While investigating the shared skb business, several drivers appeared to be calling it incorrectly in the xmit path, so this series also removes those unnecessary calls, based on the supposition mentioned in the previous point. Changes v1->v2: - icmpv6 takes subtly different types than icmpv4, like u32 instead of be32, u8 instead of int. - Since we're technically writing to the skb, we need to make sure it's not a shared one [Dave, 2017]. - Restore the original skb data after icmp_send returns. All current users are freeing the packet right after, so it doesn't matter, but future users might not. - Remove superfluous route lookup in sunvnet [Dave]. - Use NF_NAT instead of NF_CONNTRACK for condition [Florian]. - Include this cover letter [Dave]. ==================== Signed-off-by: David S.

Because xfrmi is calling icmp from network device context, it should use the ndo helper so that the rate limiting applies correctly. Signed-off-by: Jason A.

Because wireguard is calling icmp from network device context, it should use the ndo helper so that the rate limiting applies correctly. This commit adds a small test to the wireguard test suite to ensure that the new functions continue doing the right thing in the context of wireguard. It does this by setting up a condition that will definately evoke an icmp error message from the driver, but along a nat'd path. Signed-off-by: Jason A.

Because sunvnet is calling icmp from network device context, it should use the ndo helper so that the rate limiting applies correctly. While we're at it, doing the additional route lookup before calling icmp_ndo_send is superfluous, since this is the job of the icmp code in the first place. Signed-off-by: Jason A.

This introduces a helper function to be called only by network drivers that wraps calls to icmp[v6]_send in a conntrack transformation, in case NAT has been used. We don't want to pollute the non-driver path, though, so we introduce this as a helper to be called by places that actually make use of this, as suggested by Florian. Signed-off-by: Jason A.
