2021-08-14ip: Fix crash in ip address add on sub-int without exact-matchPim van Pelt1-0/+3
Type: fix Creating a sub-int without exact-match set, and subsequently adding an IPv4 or IPv6 address will crash VPP. This fix catches this situation and refuses to allow the caller to add an IPv4 or IPv6 address on an ethernet sub-int that does not have exact-match set. TESTED: Before this change, the following crashes VPP: ``` DBGvpp# cre sub TenGigabitEthernet3/0/0 1 dot1q 10 TenGigabitEthernet3/0/0.1 DBGvpp# set interface ip address TenGigabitEthernet3/0/0.1 2001:db8::1/64 <crash> ``` After the change, VPP refuses to act: ``` DBGvpp# cre sub TenGigabitEthernet3/0/0 1 dot1q 10 TenGigabitEthernet3/0/0.1 DBGvpp# set interface ip address TenGigabitEthernet3/0/0.1 192.0.2.1/30 set interface ip address: sub-interface without exact-match doesn't support IP addressing DBGvpp# set interface ip address TenGigabitEthernet3/0/0.1 2001:db8:1/64 set interface ip address: sub-interface without exact-match doesn't support IP addressing ``` Signed-off-by: Pim van Pelt <pim@ipng.nl> Change-Id: I42997db314225cd186ebb54013b5717ace7f7bd6
2021-07-28gre: set proper fib index for unnumbered interfaces, unset fib index before ↵Stanislav Zaikin1-2/+2
forwarding gre payload This commit introduces 2 fixes: 1) After GRE decapsulation sw_if_index[VLIB_TX] is set as fib index of GRE tunnel. But since GRE tunnel can work on v4 endpoints and have v6 payload, we need to reset it. In case we get IPv6 packet inside IPv4 GRE tunnel (or vice-versa) fib index can be (and usually is) invalid. 2) Check that ip-table and ip6-table are the same when setting interface as an unnumbered one. Also, fix for the pipe test include setting the right unnumbered interface for the pipes Type: fix Signed-off-by: Stanislav Zaikin <zstaseg@gmail.com> Change-Id: Id13d239cfdd21e0db6b1c9725f01c40d4af4d800

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-0/+1
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2020-04-15pg: set vnet buffer flags in pg streamsDave Barach1-0/+1
See .../extras/pg/checksum_offload.pg for a nontrivial example, which deliberately sets bogus ip and udp checksums in the generated packets, then fixes the mess with (software emulated) hardware checksum offload. Validated via "pcap dispatch trace on max 1000 buffer-trace pg-input 100". Packets stuffed into loop1-output have the configured bogus ip and udp checksums. vnet_calc_checksums_inline(...) fixes the checksums, which are correct when packets visit loop1-tx. The packet generator is a dumb robot in this regard. If you ask for a ridiculous flag combination - example: ip4 and ip6 - your mileage may vary.

2019-07-23api: binary api cleanupDave Barach1-2/+18
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.

2019-02-19tap gso: experimental supportAndrew Yourtchenko1-0/+2
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>

2018-07-15VPP-1341: fix loopback interface graph arcsDave Barach1-0/+1
Remove broken special case from l2_input.c:set_int_l2_mode(), which turns out to confuse the graph dispatch engine. The loopback TX function needs to push packets to either ethernet-input or to l2-input, based on bridge / BVI configuration. Rather than overloading a single graph arc - and making vain attempts to reconfigure it - create both arcs and use the correct one. Rewrote the loopback tx function as an idosyncratic multi-arch quad/single loop fn. Change-Id: I15b56ce641d90a11e7b3c7d23859f40e168dd7b2 Signed-off-by: Dave Barach <dave@barachs.net>
