2021-12-08net: dsa: mv88e6xxx: compute port vlan membership based on dp->bridge_dev ↵Vladimir Oltean
comparison The goal of this change is to reduce mv88e6xxx_port_vlan() to a form where dsa_port_bridge_same() can be used, since the dp->bridge_dev pointer will be hidden in a future change. To do that, we observe that the "br" pointer is deduced from a dp->bridge_dev in both cases (of a physical switch port as well as a virtual bridge). So instead of keeping the "br" pointer, we can just keep the "dp" pointer from which "br" gets derived. In the last iteration over switch ports, we must use another iterator variable, "other_dp"since now we use the "dp" variable to keep an indirect reference to the bridge. While at it, the old code used to filter only the ports which were part of the same switch as "ds". There exists a dedicated DSA port iterator for that: dsa_switch_for_each_port (which skips the ports in the tree that belong to non-local switches), so we can just use that.

2021-12-08net: dsa: mv88e6xxx: iterate using dsa_switch_for_each_user_port in ↵Vladimir Oltean
mv88e6xxx_port_check_hw_vlan Avoid a plethora of dsa_to_port() calls (some hidden behind dsa_is_*_port and some in plain sight) by keeping two struct dsa_port references: one to the port passed as argument, and another to the other ports of the switch that we're iterating over. This isn't called from the DSA initialization path, so there is no risk that we have user ports without a dp->slave populated. So the combined checks that a port isn't a DSA port, a CPU port, or doesn't have a slave net device (therefore is unused), are strictly equivalent to the simple check that the port is a user port. This is already handled by the DSA iterator. i gets replaced by other_dp->index, dsa_is_*_port calls get replaced by dsa_port_is_*, and dsa_to_port gets replaced by the respective pointer directly.

Avoid repeated calls to dsa_to_port() (some hidden behind dsa_is_user_port and some in plain sight) by keeping two struct dsa_port references: one to the port passed as argument, and another to the other ports of the switch that we're iterating over. dsa_to_port(ds, i) gets replaced by other_dp, i gets replaced by other_port which is derived from other_dp->index, dsa_is_user_port is handled by the DSA iterator.

2021-12-08net: dsa: assign a bridge number even without TX forwarding offloadVladimir Oltean
The service where DSA assigns a unique bridge number for each forwarding domain is useful even for drivers which do not implement the TX forwarding offload feature. For example, drivers might use the dp->bridge_num for FDB isolation. So rename ds->num_fwd_offloading_bridges to ds->max_num_bridges, and calculate a unique bridge_num for all drivers that set this value.

2021-12-08net: dsa: make dp->bridge_num one-basedVladimir Oltean
I have seen too many bugs already due to the fact that we must encode an invalid dp->bridge_num as a negative value, because the natural tendency is to check that invalid value using (!dp->bridge_num). Latest example can be seen in commit 1bec0f05062c ("net: dsa: fix bridge_num not getting cleared after ports leaving the bridge"). Convert the existing users to assume that dp->bridge_num == 0 is the encoding for invalid, and valid bridge numbers start from 1.

ESL(Enhanced System Lockdown) was designed to lock PCI adapter firmware images and prevent changes to critical non-volatile configuration data so that uncontrolled, malicious or unintentional modification to the adapters are avoided, ensuring it's operational state. Once this feature is enabled, the device is locked, rejecting any modification to non-volatile images. Once unlocked, the protection is off such that firmware and non-volatile configurations may be altered. Driver just reflects the capability and status of this through the ethtool private flag.

2021-12-02net/mlx5: Dynamically resize flow counters query bufferAvihai Horon
The flow counters bulk query buffer is allocated once during mlx5_fc_init_stats(). For PFs and VFs this buffer usually takes a little more than 512KB of memory, which is aligned to the next power of 2, to 1MB. For SFs, this buffer is reduced and takes around 128 Bytes. The buffer size determines the maximum number of flow counters that can be queried at a time. Thus, having a bigger buffer can improve performance for users that need to query many flow counters. There are cases that don't use many flow counters and don't need a big buffer (e.g. SFs, VFs). Since this size is critical with large scale, in these cases the buffer size should be reduced. In order to reduce memory consumption while maintaining query performance, change the query buffer's allocation scheme to the following: - First allocate the buffer with small initial size. - If the number of counters surpasses the initial size, resize the buffer to the maximum size. The buffer only grows and isn't shrank, because users with many flow counters don't care about the buffer size and we don't want to add resize overhead if the current number of counters drops. This solution is preferable to the current one, which is less accurate and only addresses SFs.

2021-12-02net/mlx5e: TC, Set flow attr ip_version earlierRoi Dayan
Setting flow attr ip_version is not related to parsing tc flow actions. It needs to be set after parsing flower matches which changes the spec. So move it outside parse_tc_fdb_actions() and set it in __mlx5e_add_fdb_flow().

2021-12-02net/mlx5: SF, silence an uninitialized variable warningDan Carpenter
This code sometimes calls mlx5_sf_hw_table_hwc_init() when "ext_base_id" is uninitialized. It's not used on that path, but it generates a static checker warning to pass uninitialized variables to another function. It may also generate runtime UBSan warnings depending on if the mlx5_sf_hw_table_hwc_init() function is inlined or not.
