From fd8caa5462e64f37cb9eebd75ffca1737dde447d Mon Sep 17 00:00:00 2001 From: Aleksandr Nogikh Date: Thu, 23 Sep 2021 16:15:41 +0000 Subject: all: replace collide mode by `async` call property Replace the currently existing straightforward approach to race triggering (that was almost entirely implemented inside syz-executor) with a more flexible one. The `async` call property instructs syz-executor not to block until the call has completed execution and proceed immediately to the next call. The decision on what calls to mark with `async` is made by syz-fuzzer. Ultimately this should let us implement more intelligent race provoking strategies as well as make more fine-grained reproducers. --- pkg/ipc/ipc.go | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'pkg/ipc/ipc.go') diff --git a/pkg/ipc/ipc.go b/pkg/ipc/ipc.go index 03b28e4ce..5bf4738ca 100644 --- a/pkg/ipc/ipc.go +++ b/pkg/ipc/ipc.go @@ -49,11 +49,11 @@ const ( type ExecFlags uint64 const ( - FlagCollectCover ExecFlags = 1 << iota // collect coverage + FlagCollectSignal ExecFlags = 1 << iota // collect feedback signals + FlagCollectCover // collect coverage FlagDedupCover // deduplicate coverage in executor FlagCollectComps // collect KCOV comparisons FlagThreaded // use multiple threads to mitigate blocked syscalls - FlagCollide // collide syscalls to provoke data races FlagEnableCoverageFilter // setup and use bitmap to do coverage filter ) -- cgit mrf-deployment
