Introduce a new optional header_ops callback called parse_protocol and a wrapper function dev_parse_header_protocol, similar to dev_parse_header. The new callback's purpose is to extract the protocol number from the L2 header, the format of which is known to the driver, but not to the upper layers of the stack. Signed-off-by:

If the socket was created with socket(AF_PACKET, SOCK_RAW, 0), skb->protocol will be unset, __skb_flow_dissect() will fail, and skb_probe_transport_header() will fall back to the offset_hint, making the resulting skb_transport_offset incorrect. If, however, there is no transport header in the packet, transport_header shouldn't be set to an arbitrary value. Fix it by leaving the transport offset unset if it couldn't be found, to be explicit rather than to fill it with some wrong value. It changes the behavior, but if some code relied on the old behavior, it would be broken anyway, as the old one is incorrect. Signed-off-by:

Florian Fainelli says: ==================== net: dsa: VLAN devices w/ filtering This patch series supports having VLAN devices on top of DSA/switch ports while the switch has VLAN filtering globally turned on (as is the case with Broadcom switches). Whether the switch does global or per-port VLAN filtering, having VLAN entries for these VLAN devices is beneficial. We take care of a few possibly problematic cases: - adding a VLAN device while there is an existing VLAN entry created by a VLAN aware bridge. The entire bridge's VLAN database and not just the specific bridge port is being checked to be safe and conserative - adding a bridge VLAN entry when there is an existing VLAN device created is also not possible because that would lead to the bridge being able to manipulate the VLAN device's VID/attributes under its feet - enslaving a VLAN device into a VLAN aware bridge since that duplicates functionality already offered by the VLAN aware bridge Here are the different test cases that were run to exercise this: ip addr flush dev gphy ip link add dev br0 type bridge echo 1 > /sys/class/net/br0/bridge/vlan_filtering ip link set dev gphy master br0 udhcpc -i br0 vconfig add rgmii_1 100 ifconfig rgmii_1.100 192.168.100.10 ping -c 2 192.168.100.1 vconfig add br0 42 bridge vlan add vid 42 dev gphy bridge vlan add vid 42 dev br0 self ifconfig br0.42 192.168.42.2 ping -c 2 192.168.42.1 ip link del rgmii_1.100 vconfig add rgmii_1 100 ifconfig rgmii_1.100 192.168.100.10 ping -c 2 192.168.100.1 echo 0 > /sys/class/net/br0/bridge/vlan_filtering ping -c 2 192.168.100.1 ip link del rgmii_1.100 echo 1 > /sys/class/net/br0/bridge/vlan_filtering vconfig add rgmii_1 100 brctl addif br0 rgmii_1 bridge vlan add vid 100 dev rgmii_1 vconfig rem rgmii_1.100 bridge vlan add vid 100 dev rgmii_1 vconfig add rgmii_1 100 bridge vlan del vid 100 dev rgmii_1 vconfig add rgmii_1 100 brctl addif br0 rgmii_1.100 ==================== Signed-off-by: -

In order to properly support VLAN filtering being enabled/disabled on a bridge, while having other ports being non bridge port members, we need to support the ndo_vlan_rx_{add,kill}_vid callbacks in order to make sure the non-bridge ports can continue receiving VLAN tags, even when the switch is globally configured to do ingress/egress VID checking. Since we can call dsa_port_vlan_{add,del} with a bridge_dev pointer NULL, we now need to check that in these two functions. We specifically deal with two possibly problematic cases: - creating a bridge VLAN entry while there is an existing VLAN device claiming that same VID - creating a VLAN device while there is an existing bridge VLAN entry with that VID Those are both resolved with returning -EBUSY back to user-space.

VLAN devices on top of a DSA network device which is already part of a bridge and with said bridge being VLAN aware should not be allowed to be enslaved into that bridge. For one, this duplicates functionality offered by the VLAN aware bridge which supports tagged and untagged VLAN frames processing and it would make things needlessly complex to e.g.: propagate FDB/MDB accordingly.

The code in mesh_path_add tries to handle the case where a duplicate entry is added to the rhashtable by doing a lookup after a failed insertion. It also tries to handle races by repeating the insertion should the lookup fail. This is now unnecessary as we have rhashtable API functions that can directly return the mathcing object.

2018 REVmd of the spec introduces the max channel switch time element which is optionally included in beacons/probes when there is a channel switch / extended channel switch element. The value represents the maximum delay between the time the AP transmitted the last beacon in current channel and the expected time of the first beacon in the new channel, in TU. Parse the value and pass it to the driver. Signed-off-by:

This extends the NL80211_CMD_ASSOCIATE event case to report NL80211_ATTR_REQ_IE similarly to what is already done with the NL80211_CMD_CONNECT events if the driver provides this information. In practice, this adds (Re)Association Request frame information element reporting to mac80211 drivers for the cases where user space SME is used. This provides more information for user space to figure out which capabilities were negotiated for the association. For example, this can be used to determine whether HT, VHT, or HE is used.

Ido Schimmel says: ==================== mlxsw: Support for shared buffers in Spectrum-2 Petr says: Spectrum-2 will be configured with a different set of pools than Spectrum-1, their sizes will be larger, and the individual quotas will be different as well. It is therefore necessary to make the shared buffer module aware of this dependence on chip type, and adjust the individual tables. In patch #1, introduce a structure for keeping per-chip immutable and default values. In patch #2, structures for keeping current values of SBPM and SBPR (pool configuration and port-pool quota) are allocated dynamically to support varying pool counts. In patches #3 to #7, uses of individual shared buffer configuration tables are migrated from global definitions to fields in struct mlxsw_sp_sb_vals, which was introduced above. Up until this point, the actual configuration is still the one suitable for Spectrum-1. In patch #8 Spectrum-2 configuration is added. In patch #9, port headroom configuration is changed to take into account current recommended value for a 100-Gbps port, and the split factor. In patch #10, requests for overlarge headroom are rejected. This avoids potential chip freeze should such overlarge requests be made. ==================== Signed-off-by: -

cap_max_headroom_size holds maximum headroom size supported. Overstepping that limit might under certain conditions lead to ASIC freeze. Query and store the value, and add mlxsw_sp_sb_max_headroom_cells() for obtaining the stored value. In __mlxsw_sp_port_headroom_set(), reject requests where the total port buffer is larger than the advertised maximum. Signed-off-by:

The recommendation for headroom size for 100Gbps port and 100m cable is 101.6KB, reduced accordingly for split ports. The closest higher number evenly divisible by cell size for both Spectrum-1 and Spectrum-2, and such that the number of cells can be further divided by maximum split factor of 4, is 102528 bytes, or 25632 bytes per lane. Update mlxsw_sp_port_pb_init() to compute the headroom taking into account this recommended per-lane value and number of lanes actually dedicated to a given port. Signed-off-by:
