2020-06-01net: use flow_indr_dev_setup_offload()Pablo Neira Ayuso
Update existing frontends to use flow_indr_dev_setup_offload(). This new function must be called if ->ndo_setup_tc is unset to deal with tunnel devices. If there is no driver that is subscribed to new tunnel device flow_block bindings, then this function bails out with EOPNOTSUPP. If the driver module is removed, the ->cleanup() callback removes the entries that belong to this tunnel device. This cleanup procedures is triggered when the device unregisters the tunnel device offload handler. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S.

2020-06-01net: flow_offload: consolidate indirect flow_block infrastructurePablo Neira Ayuso
Tunnel devices provide no dev->netdev_ops->ndo_setup_tc(...) interface. The tunnel device and route control plane does not provide an obvious way to relate tunnel and physical devices. This patch allows drivers to register a tunnel device offload handler for the tc and netfilter frontends through flow_indr_dev_register() and flow_indr_dev_unregister(). The frontend calls flow_indr_dev_setup_offload() that iterates over the list of drivers that are offering tunnel device hardware offload support and it sets up the flow block for this tunnel device. If the driver module is removed, the indirect flow_block ends up with a stale callback reference. The module removal path triggers the dev_shutdown() path to remove the qdisc and the flow_blocks for the physical devices. However, this is not useful for tunnel devices, where relation between the physical and the tunnel device is not explicit. This patch introduces a cleanup callback that is invoked when the driver module is removed to clean up the tunnel device flow_block. This patch defines struct flow_block_indr and it uses it from flow_block_cb to store the information that front-end requires to perform the flow_block_cb cleanup on module removal.

Bartosz Golaszewski says: ==================== regmap: provide simple bitops and use them in a driver I noticed that oftentimes I use regmap_update_bits() for simple bit setting or clearing. In this case the fourth argument is superfluous as it's always 0 or equal to the mask argument. This series proposes to add simple bit operations for setting, clearing and testing specific bits with regmap. The second patch uses all three in a driver that got recently picked into the net-next tree. The patches obviously target different trees so - if you're ok with the change itself - I propose you pick the first one into your regmap tree for v5.8 and then I'll resend the second patch to add the first user for these macros for v5.9. v1 -> v2: - convert the new macros to static inline functions v2 -> v3: - drop unneeded ternary operator ==================== Signed-off-by: David S.

2020-06-01vxlan: Avoid infinite loop when suppressing NS messages with invalid optionsIdo Schimmel
When proxy mode is enabled the vxlan device might reply to Neighbor Solicitation (NS) messages on behalf of remote hosts. In case the NS message includes the "Source link-layer address" option [1], the vxlan device will use the specified address as the link-layer destination address in its reply. To avoid an infinite loop, break out of the options parsing loop when encountering an option with length zero and disregard the NS message. This is consistent with the IPv6 ndisc code and RFC 4886 which states that "Nodes MUST silently discard an ND packet that contains an option with length zero" [2].

Yes, staying withing 80 columns is certainly still _preferred_. But it's not the hard limit that the checkpatch warnings imply, and other concerns can most certainly dominate. Increase the default limit to 100 characters. Not because 100 characters is some hard limit either, but that's certainly a "what are you doing" kind of value and less likely to be about the occasional slightly longer lines.

2020-05-31ice: Use coalesce values from q_vector 0 when increasing q_vectorsBrett Creeley
Currently when a VSI is built (i.e. reset, set channels, etc.) the coalesce settings will be preserved in most cases. However, when the number of q_vectors are increased the settings for the new q_vectors will be set to the driver defaults of AIM on, Rx/Tx ITR 50, and INTRL 0. This is causing issues with how the ethtool layer gets the current coalesce settings since it only uses q_vector 0. So, assume that the user set the coalesce settings globally (i.e. ethtool -C eth0) and use q_vector 0's settings for all of the new q_vectors.

2020-05-31ice: Fix transmit for all software offloaded VLANsBrett Creeley
Currently the driver does not recognize when there is an 802.1AD VLAN tag right after the dmac/smac (outermost VLAN tag). If any DCB map is applied and/or DCB is enabled this is causing the hardware to insert a VLAN 0 tag after the 802.1AD VLAN tag that is already in the packet. Fix this by preventing VLAN tag 0 from being added when any VLAN is already present after dmac/smac (software offloaded) or skb (hardware offloaded).

2020-05-31ice: allow host to clear administratively set VF MACBrett Creeley
Currently a user is not allowed to clear a VF's administratively set MAC on the PF. Fix this by allowing an all zero MAC address via "ip link set ${pf_eth} vf ${vf_id} mac 00:00:00:00:00:00". An example use case for this would be issuing a "virsh shutdown" command on a VM. The call to iproute mentioned above is part of this flow. Without this change the driver incorrectly rejects clearing the VF's administratively set MAC and prints unhelpful log messages. Also, improve the comments surrounding this change.

2020-05-31cfg80211: treat 6 GHz channels as valid regardless of capabilityJohannes Berg
If a 6 GHz channel exists, then we can probably safely assume that the device actually supports it, and then it should support most bandwidths. This will probably need to be extended to check the interface type and then dig into the HE capabilities for that though, to have the correct bandwidth check.

2020-05-31mac80211: check the correct bit for EMA APShaul Triebitz
An AP supporting EMA (Enhanced Multi-BSSID advertisement) should set bit 83 in the extended capabilities IE (9.4.2.26 in the 802.11ax D5 spec). So the *3rd* bit of the 10th byte should be checked. Also, in one place, the wrong byte was checked. (cfg80211_find_ie returns a pointer to the beginning of the IE, so the data really starts at ie[2], so the 10th byte should be ie[12]. To avoid this confusion, use cfg80211_find_elem instead).

2020-05-31mac80211: avoid using ext NSS high BW if not supportedJohannes Berg
If the AP advertises inconsistent data, namely it has CCFS1 or CCFS2, but doesn't advertise support for 160/80+80 bandwidth or "Extended NSS BW Support", then we cannot use any MCSes in the the higher bandwidth. Thus, avoid connecting with higher bandwidth since it's less efficient that way.
