2019-05-30IPsec: modify post-decrypt buf len calculationMatthew G Smith1-2/+2
For tunnel mode, after decryption the buffer length was being adjusted by adding (iv length + esp header size). Subtract it instead. Required for BFD to work on an IPsec tunnel interface. BFD verifies that the amount of received data is the expected size. It drops the packet if the buffer metadata says that the packet buffer contains more data than the packet headers say it should.

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.
