* can: dev: can_get_echo_skb(): extend to return can frame lengthMarc Kleine-Budde2021-01-1429-32/+34
| | | | | | | | | | | | | In order to implement byte queue limits (bql) in CAN drivers, the length of the CAN frame needs to be passed into the networking stack after queueing and after transmission completion. To avoid to calculate this length twice, extend can_get_echo_skb() to return that value. Convert all users of this function, too.

* can: dev: can_put_echo_skb(): extend to handle frame_lenVincent Mailhol2021-01-1431-33/+36
| | | | | | | | | | | | | | | | | | Add a frame_len argument to can_put_echo_skb() which is used to save length of the CAN frame into field frame_len of struct can_skb_priv so that it can be later used after transmission completion. Convert all users of this function, too. Drivers which implement BQL call can_put_echo_skb() with the output of can_skb_get_frame_len(skb) and drivers which do not simply pass zero as an input (in the same way that NULL would be given to can_get_echo_skb()). This way, we have a nice symmetry between the two echo functions.

* net: sfp: cope with SFPs that set both LOS normal and LOS invertedRussell King2021-01-121-14/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The SFP MSA defines two option bits in byte 65 to indicate how the Rx_LOS signal on SFP pin 8 behaves: bit 2 - Loss of Signal implemented, signal inverted from standard definition in SFP MSA (often called "Signal Detect"). bit 1 - Loss of Signal implemented, signal as defined in SFP MSA (often called "Rx_LOS"). Clearly, setting both bits results in a meaningless situation: it would mean that LOS is implemented in both the normal sense (1 = signal loss) and inverted sense (0 = signal loss). Unfortunately, there are modules out there which set both bits, which will be initially interpret as "inverted" sense, and then, if the LOS signal changes state, we will toggle between LINK_UP and WAIT_LOS states. Change our LOS handling to give well defined behaviour: only interpret these bits as meaningful if exactly one is set, otherwise treat it as if LOS is not implemented.

| | | | | | | | | | | | | | | The code that sets the DMA mask to 64 bits is bogus, it is taken from the enetc driver together with the rest of the PCI probing boilerplate. Since this patch is touching the error path to delete err_dma, let's also change the err_alloc_felix label which was incorrect. The kzalloc failure does not need a kfree, but it doesn't hurt either, since kfree works with NULL pointers.

Changes in v3: - Resolved a build warning in mv88e6xxx and tested that it actually works properly, which resulted in an extra patch (02/11). - Addressed Ido's minor feedback in commit 10/11 relating to a comment. Changes in v2: - Got rid of the vid_begin -> vid_end range too from the switchdev API. - Actually propagating errors from DSA MDB and VLAN notifiers. This series comes after the late realization that the prepare/commit separation imposed by switchdev does not help literally anybody: https://patchwork.kernel.org/project/netdevbpf/patch/20201212203901.351331-1-vladimir.oltean@nxp.com/ We should kill it before it inflicts even more damage to the error handling logic in drivers. Also remove the unused VLAN ranges feature from the switchdev VLAN objects, which simplifies all drivers by quite a bit. ==================== Link: https://lore.kernel.org/r/20210109000156.1246735-1-olteanv@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

| * mlxsw: spectrum_switchdev: remove transactional logic for VLAN objectsVladimir Oltean2021-01-121-33/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of commit 457e20d65924 ("mlxsw: spectrum_switchdev: Avoid returning errors in commit phase"), the mlxsw driver performs the VLAN object offloading during the prepare phase. So conversion just seems to be a matter of removing the code that was running in the commit phase. Ido Schimmel explains that the reason why mlxsw_sp_span_respin is called unconditionally is because the bridge driver will ignore -EOPNOTSUPP and actually add the VLAN on the bridge device - see commit 9c86ce2c1ae3 ("net: bridge: Notify about bridge VLANs") and commit ea4721751977 ("mlxsw: spectrum_switchdev: Ignore bridge VLAN events"). Since the VLAN was successfully added on the bridge device, mlxsw_sp_span_respin_work() should be able to resolve the egress port for a packet that is mirrored to a gre tap and passes through the bridge device. Therefore keep the logic as it is.
