The umtp security vulnerability poses no additional security vulnerability or risk for me so I've fallen back to mobian-pinephone-phosh-20201215 until I can get mtp on my newer Mobian system working.
On my up to date and mtp disabled current Mobian system, I tried the following (and probably some others stuff I'm forgetting here):
I reinstalled umtp-responder (after executing apt autoremove
)
The 5.9 and 5.10 kernel configs both include CONFIG_USB_FUNCTIONFS as a module.
I loaded usb_f_fs with modprobe and I also loaded libcomposite but /dev/ffs-mtp is not being created.
"systemctl list-unit-files --type=service" reports that umtp-responder.service STATE and VENDOR_PRESET are both enabled.
No mtp yet. Perhaps I'm still missing a kernel module or some service.
