Hi, FYI syzbot should report less duplicates now. A significant number of reported duplicates was one of common complaints. syzbot will now merge some slightly differently looking crashes together, for example, these 2 recently reported bugs will be merged into a single bug and reported once in future:
KASAN: use-after-free Read in skb_segment KASAN: slab-out-of-bounds Read in skb_segment You can see an example here: https://syzkaller.appspot.com/bug?id=9936b32dd3a4a278f06a2cb07eb13df9e113ca84 which contains crashes for both "BUG: unable to handle kernel paging request in cdev_del" and "general protection fault in cdev_del". Hope you will find this useful. If you are interested in heuristics details, grep for "alt:" here: https://github.com/google/syzkaller/blob/master/pkg/report/linux.go Crashes with the same alt title are merged together. In short, currently there is one cluster for "bad access in function foo" (GPF, fault, KASAN, KMSAN, corrupted list, etc); another cluster for passive hangs (task hung, task can't die); and another cluster for active stalls (rcu stall, cpu hang). These rules are based on analysis of all previously reported bugs and duplicates among them. Thanks
