[PATCH v1 3/3] Add _FORTIFY_SOURCE support for inet_ntop
Frédéric Bérat
fberat@redhat.com
Wed Mar 19 09:10:02 GMT 2025
- Create the __inet_ntop_chk routine that verifies that the builtin size
of the destination buffer is at least as big as the size given by the
user.
- Redirect calls from inet_ntop to __inet_ntop_chk or __inet_ntop_warn
- Update the abilist for this new routine
- Update the manual to mention the new fortification
