2019-02-22tapv2: coverity strikes backSteven Luong1-5/+4
while https://gerrit.fd.io/r/#/c/16590/ fixed the leaked fd which coverity reported at that time, new coverity run reports simailar leaked fd in a different goto punt path. It would be nice if coverity reported both of them at the same time. Or perhaps it did and I just missed it. Anyway, the new fix is to put the close (fd) statement prior to the return of tap_create_if routine which should catch all goto's.

2019-02-21vhost: VPP stalls with vhost performing control plane actionsSteven Luong3-214/+259
Symptom ------- With NDR traffic blasting at VPP, bringing up a new VM with vhost connection to VPP causes packet drops. I am able to recreate this problem easily using a simple setup like this. TREX-------------- switch ---- VPP |---------------| |-------| Cause ----- The reason for the packet drops is due to vhost holding onto the worker barrier lock for too long in vhost_user_socket_read(). There are quite a few of system calls inside the routine. At the end of the routine, it unconditionally calls vhost_user_update_iface_state() for all message types. vhost_user_update_iface_state() also unconditionally calls vhost_user_rx_thread_placement() and vhost_user_tx_thread_placement(). vhost_user_rx_thread_placement scraps out all existing cpu/queue mappings for the interface and creates brand new cpu/queue mappings for the interface. This process is very disruptive and very expensive. In my opinion, this area of code needs a makeover. Fixes ----- * vhost_user_socket_read() is rewritten that it should not hold onto the worker barrier lock for system calls, or at least minimize the need for doing it. * Remove the call to vhost_user_update_iface_state as a default route at the end of vhost_user_socket_read(). There is only a couple of message types which really need to call vhost_user_update_iface_state(). We put the call to those message types which need it. * Remove vhost_user_rx_thread_placement() and vhost_user_tx_thread_placement from vhost_user_update_iface_state(). There is no need to repetatively change the cpu/queue mappings. * vhost_user_rx_thread_placement() is actually quite expensive. It should be called only once per queue for the interface. There is no need to scrap the existing cpu/queue mappings and create new cpu/queue mappings when the additional queues becomes active/enable. * Change to create the cpu/queue mappings for the first RX when the interface is created. Dont remove the cpu/queue mapping when the interface is disconnected. Remove the cpu/queue mapping only when the interface is deleted. The create vhost user interface CLI also has some very expensive system calls if the command is entered with the optional keyword "server" As a bonus, This patch makes the create vhost user interface binary-api and CLI thread safe. Do the protection for the small amount of code which is thread unsafe. Change-Id: I4a19cbf7e9cc37ea01286169882e5603e6d7eb77 Signed-off-by: Steven Luong <sluong@cisco.com>

2019-02-19tap gso: experimental supportAndrew Yourtchenko14-59/+786
This commit adds a "gso" parameter to existing "create tap..." CLI, and a "no-gso" parameter for the compatibility with the future, when/if defaults change. It makes use of the lowest bit of the "tap_flags" field in the API call in order to allow creation of GSO interfaces via API as well. It does the necessary syscalls to enable the GSO and checksum offload support on the kernel side and sets two flags on the interface: virtio-specific virtio_if_t.gso_enabled, and vnet_hw_interface_t.flags & VNET_HW_INTERFACE_FLAG_SUPPORTS_GSO. The first one, if enabled, triggers the marking of the GSO-encapsulated packets on ingress with VNET_BUFFER_F_GSO flag, and setting vnet_buffer2(b)->gso_size to the desired L4 payload size. VNET_HW_INTERFACE_FLAG_SUPPORTS_GSO determines the egress packet processing in interface-output for such packets: When the flag is set, they are sent out almost as usual (just taking care to set the vnet header for virtio). When the flag is not enabled (the case for most interfaces), the egress path performs the re-segmentation such that the L4 payload of the transmitted packets equals gso_size. The operations in the datapath are enabled only when there is at least one GSO-compatible interface in the system - this is done by tracking the count in interface_main.gso_interface_count. This way the impact of conditional checks for the setups that do not use GSO is minimized. "show tap" CLI shows the state of the GSO flag on the interface, and the total count of GSO-enabled interfaces (which is used to enable the GSO-related processing in the packet path). This commit lacks IPv6 extension header traversal support of any kind - the L4 payload is assumed to follow the IPv6 header. Also it performs the offloads only for TCP (TSO - TCP segmentation offload). The UDP fragmentation offload (UFO) is not part of it. For debug purposes it also adds the debug CLI: "set tap gso {<interface> | sw_if_index <sw_idx>} <enable|disable>" Change-Id: Ifd562db89adcc2208094b3d1032cee8c307aaef9 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

-fno-common makes sure we do not have multiple declarations of the same global symbol across compilation units. It helps debug nasty linkage bugs by guaranteeing that all reference to a global symbol use the same underlying object. It also helps avoiding benign mistakes such as declaring enum as global objects instead of types in headers (hence the minor fixes scattered across the source).
