2021-09-24ip: set error number on failed intf addrMatthew Smith2-2/+8
Type: fix A subinterface that does not have exact match enabled cannot have an IP address configured on it. When this is validated in the functions which add an interface IP address for IPv4 and IPv6, a clib_error_t * is returned but api_errno is not set. The API handler uses the value of vnet_main.api_errno to set the return value in it's reply. Since it was not set, the API reports the operation succeeded. Set vnet_main.api_errno if vnet_sw_interface_supports_addressing() returns a non-null value when adding/deleting an interface IP address.

2021-09-15tap: set device name on creation via TUNSETIFFDuncan Eastoe1-17/+8
Type: fix Currently when a new TAP/TUN device is created from tap_create_if() via the TUNSETIFF ioctl(), a name is allocated by the kernel (eg. tap0). If the caller supplied a name this is subsequently set via netlink, after the device has been created. Now we request the kernel to create the new device with the caller's requested name in the first instance, thus avoiding the need to rename the device, and therefore avoiding a window where the device exists with a different name. This can be beneficial, for example, when writing systemd-udevd link files [1]. Having the TAP/TUN devices created with the requested name ensures they can be correctly matched by the OriginalName option. Writing link files might be necessary, for example, to avoid VPP and systemd-udevd racing to set the MAC address on a newly created TAP interface. systemd-udevd can be configured to not manipulate the MAC addresses of matched interfaces. These changes also resolve an issue where the created device would not be renamed if the caller requested it be moved to a different network namespace, since vnet_netlink_set_link_name() was not called in that case.

Type: fix When the local MAC address of an interface changes the rewrite strings of all adjacency types need to be updated - this patch fixes the missing case of incomplete adjacencies. I moved the update of all adj types into the adj module, since if the complete adjs were done by the ip-neighbour module and incomplete ones by adj module, that would mean two walks of the adj DB, as it is not possible to walk only a specific type.
