# Find functions making recursive calls to themselves.
|
|
# (Multiple recursion where a() calls b() which calls a() not covered.)
|
|
#
|
|
# When the recursion depth might depend on data controlled by the attacker in
|
|
# an unbounded way, those functions should use interation instead.
|
|
#
|
|
# Typical usage: scripts/recursion.pl library/*.c
