The id field in the v4l2_event_subscription structure currently described as: id len[type, int32]. But all the documentation states is: "id - ID of the event source. If there is no ID associated with the event source, then set this to 0. Whether or not an event needs an ID depends on the event type." So, the documentation clearly states that: 1. id - is the source of an event 2. type - is the type of an event 3. for some types of events there is no source and id can be 0 According to this 'id int32' is more accurate description of the field. |

syzkaller - kernel fuzzer
syzkaller
is an unsupervised coverage-guided kernel fuzzer. Linux
kernel fuzzing has the most support, akaros
, freebsd
, fuchsia
, netbsd
and windows
are supported to varying degrees.
The project mailing list is syzkaller@googlegroups.com. You can subscribe to it with a google account or by sending an email to syzkaller+subscribe@googlegroups.com.
Documentation
Initially, syzkaller was developed with Linux kernel fuzzing in mind, but now it's being extended to support other OS kernels as well. Most of the documentation at this moment is related to the Linux kernel. For other OS kernels check: Akaros, FreeBSD, Fuchsia, NetBSD, Windows.
