I see a lot of /memfd: in lsof it appears to be anonymous files (ie
temp files). I am going to guess memfd is memory file descriptor, ie
a temp file created in memory.
Usually they are going to not actually exist anywhere in a fs. And
generally the app that opens/creates them is the app that is going to
immediately use it.
if selinux is blocking it I would think it should cause some sort of
issues with the owner/application using the file.
lsof | grep "/memfd:/.nvidia" will show you the owner of the
specific file. For the nvidia_drv one it looks like Xorg (on my
system, may Wayland if you are using that) opens it.
I've attached the output of "lsof | grep "/memfd:/.nvidia"". When I ran
that, caja, a terminal, and xeyes were running.
On mine in lsof I have hundreds using the .nvidia_drv.XXXXXX one and
all have the same node in lsof so all are the same object, probably
created by the display owner.
It may be that caja itself is not granted the proper selinux
permissions to use that resource and is hence getting the error. Ie
the error may not be that the file is missing options but that the
application is not allowed access to the file.
When I ran the renames and deletes in caja, they all worked properly
even though I received the SELinux alerts in some cases. Would that
have been so if caja was lacking SELinux permissions?
you might try the restorecon against the caja executable itself
