| 3 | "GWP-ASan is a sampled allocator framework that assists in finding " |
| 4 | "use-after-free and heap-buffer-overflow bugs in production environments. " |
| 5 | "It informally is a recursive acronym, 'GWP-ASan Will Provide Allocation " |
| 6 | "SANity'. " |
| 7 | "GWP-ASan is based on the classic Electric Fence Malloc Debugger " |
| 8 | "<https://linux.die.net/man/3/efence>, with a key adaptation. Notably, we " |
| 9 | "only choose a very small percentage of allocations to sample, and apply " |
| 10 | "guard pages to these sampled allocations only. The sampling is small " |
| 11 | "enough to allow us to have very low performance overhead." |
