Type: fix vnet_delete_hw_interface() calls vec_free on rx_queue_indices. function vnet_hw_if_unregister_all_rx_queues() is used to free rx_queue_indices which is also called by vnet_delete_hw_interface(). So, second vec_free is redundant. Change-Id: Ibda4be38fd122d33532bb384c97b0b9e5f441134 Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

2021-09-27fib: fix crash on exporter tracker removeVladislav Grishenko1-4/+3
Exported entries are tracked only when the prefix found in the export FIB is really attached, exporter tracker is not set if the export entry is not valid for export, ex. for special FIB entries - default route, zeronet, mcast and broadcast prefixes. When imported entries need to be purged, such unset exporter tracker is being removed by non-initialized index with absent delegate entries, causing corresponding assert and crash.

2021-09-27gso: do not gro on small packetsAloys Augustin1-3/+41
This has two benefits: fix an issue where small packets can be padded to 64 bytes by the ethernet layer, and we included these bytes in the tcp stream; and also if we receive a small packet, it signals that this tcp stream is likely more latency-sensitive than throughput- sensitive, and skipping gro buffering should be beneficial.

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.

Defaulting to /run/vpp/app_ns_sockets/${ns_id} (2) If a netns is passed, the sock_name has to be abstract (i.e. start with '@'). It will default to `@vpp/session/${ns_id}` and will be created in the provided netns.

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.
