What did you do?
sys/unix is missing a number of types for fanotify.
$ grep ^struct /usr/include/linux/fanotify.h struct fanotify_event_metadata { struct fanotify_event_info_header { struct fanotify_event_info_fid { struct fanotify_event_info_pidfd { struct fanotify_event_info_error { struct fanotify_response { struct fanotify_response_info_header { struct fanotify_response_info_audit_rule {
The only two types defined are $ grep -i 'type Fanotify' src/cmd/vendor/golang.org/x/sys/unix/* src/cmd/vendor/golang.org/x/sys/unix/ztypes_linux.go:type FanotifyEventMetadata struct { src/cmd/vendor/golang.org/x/sys/unix/ztypes_linux.go:type FanotifyResponse struct {
To usefully use fanotify, all c structs need to have go counterparts.
What did you see happen?
Trying to use https://github.com/s3rj1k/go-fanotify only to discover that it (as is) only uses/exposes a limited part of fanotify, and when trying to change it (notably to not require root privs), I needed to parse the additional, unsupported, structs.
What did you expect to see?
Full coverage of fanotify structs as go types.
