- FUSE Passthrough — The Linux Kernel documentation
Standard tools like lsof, which typically inspect process file descriptor tables, would not be able to identify that this file is still open by the system on behalf of the FUSE filesystem This makes it difficult for system administrators to track resource usage or debug issues related to open files (e g , preventing unmounts)
- FUSE — The Linux Kernel documentation
By default FUSE doesn’t check file access permissions, the filesystem is free to implement its access policy or leave it to the underlying file access mechanism (e g in case of network filesystems) This option enables permission checking, restricting access based on file mode It is usually useful together with the ‘allow_other’ mount
- When does a (FUSE) filesystem check acces rights?
A user makes a filesystem-related request (i e ls) The kernel notices that that specific filesystem is mounted using FUSE; The request is forwarded to the custom filesystem (created using FUSE) Here you can access the request's metadata using fuse_context which will return a uid,gid,pid
- filesystems - Fuse file system with “default permission . . .
Note that you can in principle mount FUSE filesystems as any user So when the test user executed touch, first he opened the file on the fuse-mounted filesystem Because you used default_permissions, the system checked if user test is allowed to create files in this particular directory (which apparently succeeded), and then let fusexmp create
- What happens if there are more than one FUSE programs acting . . .
@CuriousKimchi The mount in the subdirectory completely hides whatever was in the upper directory The top FUSE mount can still mostly prevent access if it makes the mount point impossible to access; but processes that have a handle (e g their current directory) in the lower FUSE any time after it's mounted will retain their handle even if the access conditions above the mount point change
- 20 Accessing File Systems with FUSE - SUSE Documentation
This means you can configure and mount a file system as an unprivileged user Normally, you need to be root for this task FUSE alone is a kernel module Combined with plug-ins, it allows you to extend FUSE to access almost all file systems like remote SSH connections, ISO images, and more
