To find any files with a missing copyright declaration, use the following script:
# ========================
#!/bin/sh
# Find files with copyright declarations, and list their file extensions
exts=$(grep -Ril --exclude-dir .git --exclude-dir 3rdparty\
--exclude-dir programs/fuzz 'Copyright.*Arm' | sed '
s/.*\///
s/.*\./*./
s/.*/-name "&"/
' | sort -u | sed -n '
:l
N
$!bl
s/\n/ -o /gp
')
# Find files with file extensions that ususally include copyright extensions,
# but don't include a copyright declaration themselves.
eval "find\
'(' -path './.git' -o -path './3rdparty' -o -path './programs/fuzz' ')' -prune\
-o ! -path './tests/data_files/format_pkcs12.fmt'\
! -path './programs/psa/psa_constant_names_generated.c'\
'(' $exts ')' -print" | xargs grep -Li 'Copyright.*Arm'

# 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
