From: Jamal Hadi Salim <jhs@mojatatu.com>

Changes from V2:
 1) Dont initialize tmp on stack (Stephen)
 2) Dont look at the return code of snprintf (Dominique)
 3) Set errno to EINVAL instead of returning -EINVAL for consistency (Dominique)

Changes from V1:
 1) use snprintf instead of sprintf and fix corresponding error message.
 Caught-by: Dominique Martinet <asmadeus@codewreck.org>
 2) Fix memory leak and extraneous free() in error path

Jamal Hadi Salim (2):
  bpf: Fix segfault when custom pinning is used
  bpf: Fix mem leak and extraneous free() in error path
