Per interface, next hop graph node can be customized with vnet_hw_interface_rx_redirect_to_node function, but it doesn't work well for af-packet type interface. In current implementation, with function af_packet_set_interface_next_node invoked next hop graph node index can be set to apif->per_interface_next_index, but it's not set to next0 properly for packet processing in af_packet_device_input_fn.

2019-09-27tap: fix tap interface not working on Arm issueLijian.Zhang1-1/+6
The VPP code tries to set all userspace memory in the table via IOCTL to VHOST_SET_MEM_TABLE. But on aarch64, the userspace address range is larger (48 bits) than that on x86 (47 bits). Below is an segment from /proc/[vpp]/maps. fffb41200000-fffb43a00000 rw-s 00000000 00:0e 532232 /anon_hugepage (deleted) Instead of setting all userspace memory space to vhost-net, will only set the address space reserved by pmalloc module during initialization.

2019-09-20devices: vhost-user crashes displaying show trace for deleted interfaceSteven Luong1-6/+10
After the trace is collected and if the interface is then deleted, show trace may crash for the debug image. This is due to the additional check in pool_elt_at_index() to make sure that the block is not free. The fix is to do the check in vhost format trace and return "interface deleted" Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I0744f913ba6146609663443f408d784067880f93 (cherry picked from commit 5cd987dda679fe50b9cd7a834bb9162db39ade78)

2019-07-23api: binary api cleanupDave Barach4-10/+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.

2019-07-23devices: vhost handling VHOST_USER_SET_FEATURESSteven Luong1-0/+1
Some combinations of new qemu (2.11) and old dpdk (16.10) may send VHOST_USER_SET_FEATURES at the end of the protocol exchange which the vhost interface is already declared up and ready. Unfortunately, the process of VHOST_USER_SET_FEATURES will cause the interface to go down. Not sure if it is correct or needed. Because there is no additional messages thereafter, the hardware interface stays down. The fix is to check the interface again at the end of processing VHOST_USER_SET_FEATURES. If it is up and ready, we bring back the hardware interface. Type: fix Change-Id: I490cd03820deacbd8b44d8f2cb38c26349dbe3b2 Signed-off-by: Steven Luong <sluong@cisco.com>

2019-07-18vlib: convert frame_index into real pointersAndreas Schultz1-1/+1
The fast path almost always has to deal with the real pointers. Deriving the frame pointer from a frame_index requires a load of the 32bit frame_index from memory, another 64bit load of the heap base pointer and some calculations. Lets store the full pointer instead and do a single 64bit load only. This helps avoiding problems when the heap is grown and frames are allocated below vm->heap_aligned_base.

2019-05-28tap: crash in multi-thread environmentMohsin Kazmi3-5/+4
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.

2019-05-16init / exit function orderingDave Barach1-6/+6
The vlib init function subsystem now supports a mix of procedural and formally-specified ordering constraints. We should eliminate procedural knowledge wherever possible. The following schemes are *roughly* equivalent: static clib_error_t *init_runs_first (vlib_main_t *vm) { clib_error_t *error; ... do some stuff... if ((error = vlib_call_init_function (init_runs_next))) return error; ... } VLIB_INIT_FUNCTION (init_runs_first); and static clib_error_t *init_runs_first (vlib_main_t *vm) { ... do some stuff... } VLIB_INIT_FUNCTION (init_runs_first) = { .runs_before = VLIB_INITS("init_runs_next"), }; The first form will [most likely] call "init_runs_next" on the spot. The second form means that "init_runs_first" runs before "init_runs_next," possibly much earlier in the sequence. Please DO NOT construct sets of init functions where A before B actually means A *right before* B. It's not necessary - simply combine A and B - and it leads to hugely annoying debugging exercises when trying to switch from ad-hoc procedural ordering constraints to formal ordering constraints.
