Before reporting an issue, please ensure you are using the latest release of fsnotify, and please
search for existing issue to avoid duplicates.

Describe the bug

issue: https://github.com/kubernetes/kubernetes/issues/103500

Under ARM64 environment, POD log parameter is the wireless cycle of log after Follow.

I looked at the kubelet source code and found that kubelet watch for changes to the container log file via fsnotify and outputs the new log to the terminal when new logs are generated.

https://github.com/kubernetes/kubernetes/blob/fbffe056dd03bd9c746e8819ad22043d640a4489/pkg/kubelet/kuberuntime/logs/logs.go#L438-L454

My guess is that fsnotify reported the events that did not meet expectations, causing the kubelet to re-read the entire log file each time (original log + new log), so what we see in the terminal is that the log keeps polling for a refresh.

and I extracted the key code from the kubelet and verified the issue on the arm64 architecture, but the same code works fine on amd64.

on arm64, fsnotify intermittently reports CHMOD event events, even if there are no new changes to this file, as shown below:

I0119 16:28:57.247735  904671 main.go:416] fsnotify.Chmod
I0119 16:28:57.754465  904671 main.go:404] fsnotify.Write
I0119 16:28:59.720545  904671 main.go:416] fsnotify.Chmod
I0119 16:28:59.779180  904671 main.go:416] fsnotify.Chmod

I0119 16:29:10.604148  904671 main.go:416] fsnotify.Chmod

on amd64, it work well:

[root@master kubelet]# go run main.go

I0119 16:37:26.417523 2949984 main.go:404] fsnotify.Write

Can anyone help me? I don't know what's causing this，Thanks!

To Reproduce

wecom-temp-2f08e0a10e1f8406a39e5278f360fa90

Expected behavior
A clear and concise description of what you expected to happen.

When the file changes, fsnotify reports the correct event instead of always reporting the CHMOD event

Which operating system and version are you using?

[root@dce-18-18-10-202 kubelet-fsnotify]# uname -a
Linux dce-18-18-10-202 4.19.90-23.8.v2101.ky10.aarch64 #1 SMP Mon May 17 17:07:38 CST 2021 aarch64 aarch64 aarch64 
GNU/Linux

Additional context
If applicable, add screenshots or a code sample to help explain your problem.

could you please strace the command on arm64 to see what happens? If you run just the test() function, does it end up in a loop with CHMOD notifications?

With #528 the CI now also runs in linux/arm64 and darwin/arm64, where it seems to work fine.

The inotify backend is pretty simple: unlike some other backends we never create our own events and it's little more than a wrapper to convert the events inotify send us to what we want to send on the channel. It might accidentally drop some events or have other issues, but erroneously generating events that weren't reported by the kernel is not something I can see happening.

I can't tell you what is sending these events; maybe kubernetes does something with these files, or something else on your system. I suspect these events are genuine and that something is causing these events to be sent; that this happens on arm64 isn't really all that important. But it's hard to be sure: it could also be a bug somewhere, but if it is, then it's probably in the Linux kernel.

One possibility is that there are still open file descriptors when files get removed (by any process). inotify will immediately generate a IN_ATTRIB event (fsnotify.Chmod), and then a IN_REMOVE (fsnotify.Remove) when the descriptor is closed. Or maybe something else is touching the file like some background process or some such; inotify(7) documents IN_ATTRIB as:

IN_ATTRIB (*)
      Metadata changed—for example, permissions (e.g., chmod(2)),
      timestamps (e.g., utimensat(2)), extended attributes
      (setxattr(2)), link count (since Linux 2.6.25; e.g., for the
      target of link(2) and for unlink(2)), and user/group ID
      (e.g., chown(2)).

So the fsnotify.Chmod event doesn't map exactly to a "chmod" operation, but it's the closest thing we have and there isn't really any way we can do better. Maybe when #114 gets implemented it will be improved, but I haven't looked much at fanotify yet.

This is something kubernetes can handle better though. Looking at kubernetes/kubernetes#107634 it seems it just unconditionally assumes a logfile was recreated on Chmod. In kubernetes/kubernetes#73041 (comment) it was mentioned that "I've seen the Chmod event coming from fsnotify instead of Rename or Create when the log file was replaced with rename(2)", but I can't really reproduce that, and other people mentioned they can't either. And even if I could reproduce it, unconditionally assuming a Chmod event made the file disappear would still be the wrong behaviour IMO.

My suggestion for kubernetes (@giuseppe, @pacoxu) would be to:

  • remove the Chmod event from the kubernetes handling, or handle it a bit smarter somehow. It's not really clear to me what problem having Chmod in there solved in the first place (I wasn't maintaining this in 2019), and it may have been fixed quite a while ago.

  • watch the parent directory the file is in, rather than the file itself. Watching files is kind of tricky for a number of reasons and not something I would recommend doing in most cases. Watching the directory is usually more reliable.

And in general:

  • You can try running inotifywait -m /path/to/file/or/dir and see what that does; I bet that should show the same problem, demonstrating it's not an issue in this library but either because something on your system is doing stuff with those files, or a bug in inotify.

  • Verify fsnotify 1.6.0 still has this issue; it seems kubernetes updated their version in update fsnotify to v1.6.0 kubernetes/kubernetes#113037, but dunno if that's in a release yet (probably not, as it was 3 days ago).

  • The strace you posted earlier just contains the result from the Go compile process; run go build and then strace program.

And finally to @saurori, you're really seeing a different issue. I don't think that's a problem in fsnotify either, but you're using macOS with the kqueue backend which is significantly more complex than inotify (and also shares no code with it), so it certainly could be. As I mentioned before, I can't reproduce it though, either in my macOS VM, or in the CI, so I suspect it may also just be a process doing stuff, but hard to be sure. It might be the Spotlight indexing thing: https://github.com/fsnotify/fsnotify#macos – either way, open a new issue for it if you really think it's a problem in fsnotify and we can investigate further, rather than discussing two issues here.

Thanks, @arp242 👍

I think the root cause of this issue is not clear yet, it could be a kernel issue. But in Kubernetes, this can be avoided. So I proposed kubernetes/kubernetes#107634 but the Kubernetes community didn't take it up, they thought it lacked sufficient testing.

So for kubernetes, I agree that more smarter handling of Chmod events is a better choice.

I'll close this for now since I don't think this is a problem in fsnotify, to the best of my ability to figure out.
