This results in nearly all functions with the possibility of stack corruption getting stack canaries, because it applies to any function taking a reference to the frame or with a local array rather than just the functions with arrays larger than 8 bytes. It was developed for use in Chrome (and Chrome OS) and has also been adopted by various other distributions (Arch, Fedora, Ubuntu, etc). The code size increase ranges from ~1.5% to ~2.5%, compared to ~0.3% to ~0.7% with the more conservative switch. The increase in the performance loss is usually minimal. The overall size increase once everything other than C and C++ code is taken into account is minimal, and it greatly improves the mitigation of stack buffer overflow vulnerabilities. https://lwn.net/Articles/584225/ Change-Id: I55a9fdbf5777ccdeed9f2e9a23c73bb94ad7b646 |
