udev,network: warn when .link or .network file has no [Match] section Closes #12098. 2019-04-20 14:40:24 +02:00			`[Match]`

udev: link-config - move naming policy from udev rules This introduces a new key NamePolicy, which takes an ordered list of naming policies. The first successful one is applide. If all fail the value of Name (if any) is used. The possible policies are 'onboard', 'slot', 'path' and 'mac'. This patch introduces a default link file, which replaces the equivalent udev rule. 2013-10-28 00:19:59 +01:00			`[Link]`
link-config: add "keep" policy and use it by default If "keep" policy is specified, and the interface has a name that is NET_NAME_USER or NET_NAME_RENAMED, we stop processing rules. "keep" should probably be specified either first or last depending on the preference. This partially reimplements 55b6530baacf4658a183b15b010a8cf3483fde08, in the sense that if the "keep" policy is not specified, and if the interface has a NamingPolicy, it will be renamed, even if it had a name previously. So this breaks backwards compatibility in this case, but that's more in line with what users expect. Closes #9006. 2019-01-16 14:26:29 +01:00			`NamePolicy=keep kernel database onboard slot path`
network: set AlternativeNamesPolicy= in 99-default.link 2019-12-17 00:30:38 +09:00			`AlternativeNamesPolicy=database onboard slot path`
udev: link-config - add mac address policy This introduces a new key MACAddressPolicy. The possible policies are 'persistent' and 'random'. 'persistent' will do nothing if the current address is the hardware address, but if the hardware does not have an address (or another address is set for whatever reason), we will generate an address which will be random, but persistent between boots (based on machineid and persistent netif name). 'random' will do nothing if the kernel already set a random address, otherwise it will generate a random one and use that instead. This patch sets MACAddressPolicy=persistent in the default .link file. 2013-10-28 00:19:59 +01:00			`MACAddressPolicy=persistent`
