[PATCH] bpf: fix a missing check of return value

check_reg_arg() may fail and not mark correct data in "env". This fix inserts a check that ensures check_reg_arg() is successful, and if it is not, the fix stops further operations and returns an error upstream. Signed-off-by: Kangjie Lu --- kernel/bpf/verifier.c | 4 +++- 1 file changed, 3 ins
