2019-03-12ICMP46 error: Clone first buffer instead of "truncating" original bufferOle Troan3-52/+57
Previous code was walked buffer chain, effectively trying to "truncate" the chain, reset the length of first buffer and reused that as the ICMP error message. That could have issues in cases there were other users of the buffer chain. Update to clone the first buffer in chain, and use that for the ICMP error message instead.

2019-03-12FIB: crash when deleting default routeNeale Ranns1-9/+0
when adding a recursive path the table is locked so that it can be removed when the last recursive path is removed. however, not all RR source'd prefixs use a recursive path. so flushing the table of all RR source'd entries is not correct.

Avoid the cache miss consequences of spraying [functionally harmless] junk into un-prefetched rewrite space. As things stand, several tunnel encap rewrites set rewrite data_bytes = 0, and take a performance hit due to unwanted speculative copying.

2019-03-06vmbus: fix bug that breaks multiple netvsc vdevsMatthew Smith1-2/+2
VPP supports two DPDK drivers for managing netvsc devices on Azure/Hyper-V. The new netvsc PMD looks a lot like other PCI-based PMDs but it requires recently added kernel support (>=4.17). The older vdev_netvsc is an abstraction that manages the mlx4 VF and tap device underlying the netvsc interface using the failsafe PMD. Distros with older kernels (e.g. RHEL/CentOS 7.x) have to use vdev_netvsc. At startup, netvsc devices are processed and an attempt is made to initialize them for management by the netvsc PMD. If that fails, then vlib_vmbus_bind_to_uio() returns early and the device can be initialized for management by vdev_netvsc. The operation that is supposed to fail if the netvsc PMD cannot be used is registration of the netvsc device type ID with the uio_hv_generic driver. This operation is attempted exactly once so it does not fail for netvsc devices processed after the first one and they end up in a state where they cannot be initialized for use by vdev_netvsc. Only unset uio_new_id_needed if uio_hv_generic registration succeeds. Change-Id: I6be925d422b87ed24e0f4611304cc3a6b07a34fd Signed-off-by: Matthew Smith <mgsmith@netgate.com>
