2018-07-04Fix clib_bitmap_next_clear() function when no clear bits leftJohn Lo1-0/+3
If the bitmap has no bit clear after the input bit position i, the function will return i even if its bit is set. Fix is to return the next bit just beyond the free bitmap. This can cause IP neighbor scan crash in ip_neighbor_scan() with a debug image. With production image, ip_neighbor_scan() may still function, AFAICT, with extra neighbor delete attempts for entries already deleted, until these entries are reused for new neighbors.

2018-05-10vppinfra: use count_trailing_zeros in sparse_vec_indexDamjan Marion1-1/+1
It is much cheaper to use ctzll than to do shift,subtract and mask in likely case when we are looking for 1st set bit in the uword. Change-Id: I31954081571978878c7098bafad0c85a91755fa2 Signed-off-by: Damjan Marion <damarion@cisco.com>
