2020-09-04virtio: remove kernel virtio header dependenciesMohsin Kazmi2-10/+6
Type: refactor tap, virtio and vhost use virtio/vhost header files from linux kernel. Different features are supported on different kernel versions, making it difficult to use those in VPP. This patch removes virtio/vhost based header dependencies to local header files. Change-Id: I064a8adb5cd9753c986b6f224bb075200b3856af Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

2020-07-07tap: fix the tun sndbuf value for kernel 4.20 and laterMohsin Kazmi1-4/+16
Type: fix From kernel 4.20, xdp support has been added in tun_sendmsg. If sndbuf == INT_MAX, kernel executes xdp data path for tun driver which assumes packets are ethernet frames. This patch is avoiding the xdp data path in kernel by setting the sendbuf value < INT_MAX. Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com> Change-Id: Ia4aa54b177b96d56a2d513d18d26ca01d5b88929

2020-05-04misc: binary api fuzz test fixesDave Barach1-1/+1
Add a hook to src/vlibapi/api_shared.c to fuzz (screw up) binary API messages, e.g. by xoring random data into them before processing. We specifically exempt client connection messages, and inband debug CLI messages. We step over msg_id, client index, client context, and sw_if_index. Otherwise, "make test" vectors fail too rapidly to learn anything. The goal is to reduce the number of crashes caused to zero. We're fairly close with this patch. Add vl_msg_api_max_length(void *mp), which returns the maximum plausible length for a binary API message. Use it to hardern vl_api_from_api_to_new_vec(...) which takes an additional argument - message pointer - so it can verify that astr->length is sane. If it's not sane, return a u8 *vector of the form "insane astr->length nnnn\0". Verify array lengths in vl_api_dhcp6_send_client_message_t_handler(...) and vl_api_dhcp6_pd_send_client_message_t_handler(...). Add a fairly effective binary API fuzz hook to the unittest plugin, and modify the "make test" framework.py to pass "api-fuzz { on|off }" to enable API fuzzing: "make API_FUZZ=on TEST=xxx test-debug" or similar Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I0157267652a163c01553d5267620f719cc6c3bde

2019-07-23api: binary api cleanupDave Barach1-2/+4
Multiple API message handlers call vnet_get_sup_hw_interface(...) without checking the inbound sw_if_index. This can cause a pool_elt_at_index ASSERT in a debug image, and major disorder in a production image. Given that a number of places are coded as follows, add an "api_visible_or_null" variant of vnet_get_sup_hw_interface, which returns NULL given an invalid sw_if_index, or a hidden sw interface: - hw = vnet_get_sup_hw_interface (vnm, sw_if_index); + hw = vnet_get_sup_hw_interface_api_visible_or_null (vnm, sw_if_index); if (hw == NULL || memif_device_class.index != hw->dev_class_index) return clib_error_return (0, "not a memif interface"); Rename two existing xxx_safe functions -> xxx_or_null to make it obvious what they return.

2019-05-28tap: crash in multi-thread environmentMohsin Kazmi1-4/+0
In tap tx routine, virtio_interface_tx_inline, there used to be an interface spinlock to ensure packets are processed in an orderly fashion clib_spinlock_lock_if_init (&vif->lockp); When virtio code was introduced in 19.04, that line is changed to clib_spinlock_lock_if_init (&vring->lockp); to accommodate multi-queues. Unfortunately, althrough the spinlock exists in the vring, it was never initialized for tap, only for virtio. As a result, many nasty things can happen when running tap interface in multi-thread environment. Crash is inevitable. The fix is to initialize vring->lockp for tap and remove vif->lockp as it is not used anymore.

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.
