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=$(grep -Ril --exclude-dir .git 'Copyright.*Arm' | sed ' s/.*\./-name "*./ s/$/"/ ' | 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' -prune -o\ ! -path './tests/data_files/format_pkcs12.fmt'\ ! -path './programs/psa/psa_constant_names_generated.c'\ '(' $exts ')' -print" | xargs grep -Li 'Copyright.*Arm' # ======================== Signed-off-by: Bence Szépkúti <bence.szepkuti@arm.com>

# 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
