- (Object) CanonicalizeIP(ifcfg)

Canonicalize static ip configuration obtained from sysconfig. (suse#46885)

Static ip configuration formats supported by sysconfig: 1) IPADDR=10.0.0.1/8 2) IPADDR=10.0.0.1 PREFIXLEN=8 3) IPADDR=10.0.0.1 NETMASK=255.0.0.0

Features: - IPADDR (in form <ip>/<prefix>) overrides PREFIXLEN,
- NETMASK is used only if prefix length unspecified) - If prefix length and NETMASK are unspecified, 32 is implied.

Canonicalize it to: - IPADDR="<ipv4>" PREFIXLEN="<prefix>" NETMASK="<netmask>") in case of IPv4 config E.g. IPADDR=10.0.0.1 PREFIXLEN=8 NETMASK=255.0.0.0 - IPADDR="<ipv6>" PREFIXLEN="<prefix>" NETMASK="") in case of IPv6 config E.g. IPADDR=2001:15c0:668e::5 PREFIXLEN=48 NETMASK=""

Parameters:

  • ifcfg

    a map with netconfig (ifcfg) configuration for a one device

Returns:

  • a map with IPADDR, NETMASK and PREFIXLEN adjusted if IPADDR is present. Returns original ifcfg if IPADDR is not present. In case of error, returns nil.

- (Object) GetType(dev)

Detects device type according cached data

If cached ifcfg for given device is found it is used as parameter for GetTypeFromIfcfgOrName( dev, ifcfg). Otherwise is device handled as unconfigured and result is equal to GetTypeFromIfcfgOrName( dev, nil)

Parameters:

  • dev

    device name

Returns:

  • detected device type

- (Object) GetTypeFromSysfs(dev)

Determines device type according /sys/class/net/<dev>/type value

Firstly, it uses /sys/class/net/<dev>/type for basic decision. Obtained values are translated to device type according <kernel src>/include/uapi/linux/if_arp.h. Sometimes it uses some other checks to specify a "subtype". E.g. in case of "eth" it checks for presence of "wireless" subdir to determine "wlan" device.

Returns:

  • return device type or nil if nothing known found
