Subject: [PATCH net-next 0/4] netconsole: selftest for userdata overflow
Date: Wed, 04 Dec 2024 08:40:41 -0800 [thread overview]
Message-ID: <20241204-netcons_overflow_test-v1-0-a85a8d0ace21@debian.org> (raw)
Implement comprehensive testing for netconsole userdata entry handling,
demonstrating correct behavior when creating maximum entries and
preventing unauthorized overflow.
Refactor existing test infrastructure to support modular, reusable
helper functions that validate strict entry limit enforcement.
Also, add a warning if update_userdata() sees more than
MAX_USERDATA_ITEMS entries. This shouldn't happen and it is a bug that
shouldn't be silently ignored.
