| | | | | | | | | | | | This allows to limit units to machines that run on a certain firmware type. For device tree defined machines checking against the machine's compatible is also possible.
* | network: neighbor: Always add neighbors with replaceWilliam A. Kennington III2021-04-281-4/+0
|/ | | | | | | | | | We were duplicating setting flags for the message and a combination of NLM_F_APPEND and NLM_F_CREATE which does not make sense. We should have been using NLM_F_REPLACE and NLM_F_CREATE since the kernel can dynamically create neighbors prior to us adding an entry. Otherwise, we can end up with cases where the message will time out after ~25s even though the neighbor still gets added. This delays the rest of the setup of the interface even though the error is ultimately ignored.

* | network: update comment and log messageYu Watanabe2021-04-261-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | After 4b30f2e135ee84041bb597edca7225858f4ef4fb, reading stable_secret sysctl property fails with -ENOMEM, instead of -EIO. This is due to read_full_virtual_file() uses read() as the backend while read_one_line_file() uses fgetc(). And each functions return different error on fails. Anyway, the failure is harmless here. So, the log message and comment is updated. Closes one of the issues in #19410.

|\ \ | | | | | | network: enable DHCP broadcast flag if required by interface
| * | network: enable DHCP broadcast flag if required by interfaceViktor Mihajlovski2021-04-214-4/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some interfaces require that the DHCPOFFER message is sent via broadcast if they can't receive unicast messages before they've been configured with an IP address. E.g., s390 ccwgroup network interfaces operating in layer3 mode face this limitation. This can prevent the interfaces from receiving an IP address via DHCP, if the have been configured for layer3. To allow DHCP over such interfaces, we're introducing a new device property ID_NET_DHCP_BROADCAST which can be set for those. The networkd DHCP client will check whether this property is set for an interface, and if so will set the broadcast flag, unless the network configuration for the interface has an explicit RequestBroadcast setting. Besides that, we're adding a udev rule to set this device property for ccwgroup devices operating in layer3 mode, which is the case if the ID_NET_DRIVER property is qeth_l3. Supercedes #18829
