1name: "GWP-ASan" 2description: 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." 12 13third_party { 14 url { 15 type: GIT 16 value: "https://github.com/llvm/llvm-project.git" 17 } 18 version: "8f5e1755ca385566c0352a9bd292218cebfd3d0b" 19 license_type: NOTICE 20 last_upgrade_date { year: 2019 month: 8 day: 21 } 21} 22
