[PATCH] xdp_rxq_info_user: Fix null pointer dereference. Replace malloc/memset with calloc.

2020-06-12 Thread Gaurav Singh
Memset on the pointer right after malloc can cause a null pointer deference if it failed to allocate memory. A simple fix is to replace malloc/memset with a calloc() Fixes: 0fca931a6f21 ("samples/bpf: program demonstrating access to xdp_rxq_info") Signed-off-by: Gaurav Singh ---
