Revert ncsi: Propagate carrier gain/loss events to the NCSI controller

2023-11-15T09:59:44Z

This reverts commit 3780bb29311eccb7a1c9641032a112eed237f7e3. The cited commit introduced unwanted behavior. The intent for the commit was to be able to detect carrier loss/gain for just the NIC connected to the BMC. The unwanted effect is a carrier loss for auxiliary paths also causes the BMC to lose carrier. The BMC never regains carrier despite the secondary NIC regaining a link. This change, when merged, needs to be backported to stable kernels. 5.4-stable, 5.10-stable, 5.15-stable, 6.1-stable, 6.5-stable Fixes: 3780bb29311e ("ncsi: Propagate carrier gain/loss events to the NCSI controller") CC: stable@vger.kernel.org Signed-off-by: Johnathan Mantey Reviewed-by: Simon Horman Signed-off-by: David S.

ncsi: Propagate carrier gain/loss events to the NCSI controller

2023-09-18T06:06:05Z

Report the carrier/no-carrier state for the network interface shared between the BMC and the passthrough channel. Without this functionality the BMC is unable to reconfigure the NIC in the event of a re-cabling to a different subnet. Signed-off-by: Johnathan Mantey Signed-off-by: David S. Miller

net/ncsi: change from ndo_set_mac_address to dev_set_mac_address

2023-06-09T09:32:51Z

Change ndo_set_mac_address to dev_set_mac_address because dev_set_mac_address provides a way to notify network layer about MAC change. In other case, services may not aware about MAC change and keep using old one which set from network adapter driver. As example, DHCP client from systemd do not update MAC address without notification from net subsystem which leads to the problem with acquiring the right address from DHCP server.

net/ncsi: clear Tx enable mode when handling a Config required AEN

2023-04-28T08:35:33Z

ncsi_channel_is_tx() determines whether a given channel should be used for Tx or not. However, when reconfiguring the channel by handling a Configuration Required AEN, there is a misjudgment that the channel Tx has already been enabled, which results in the Enable Channel Network Tx command not being sent. Clear the channel Tx enable flag before reconfiguring the channel to avoid the misjudgment.

net: Use of_property_read_bool() for boolean properties

2023-03-16T17:41:28Z

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. Convert reading boolean properties to of_property_read_bool().

net/ncsi: Silence runtime memcpy() false positive warning

2022-12-07T01:29:14Z

The memcpy() in ncsi_cmd_handler_oem deserializes nca->data into a flexible array structure that overlapping with non-flex-array members (mfr_id) intentionally. Since the mem_to_flex() API is not finished, temporarily silence this warning, since it is a false positive, using unsafe_memcpy().

genetlink: start to validate reserved header bytes

2022-08-29T11:47:15Z

We had historically not checked that genlmsghdr.reserved is 0 on input which prevents us from using those precious bytes in the future. One use case would be to extend the cmd field, which is currently just 8 bits wide and 256 is not a lot of commands for some core families. To make sure that new families do the right thing by default put the onus of opting out of validation on existing families.
