Add FUNCTIONFS_ENDPOINT_ALLOC to ioctl_defines and mediaprovider.te
We've got a SELinux warning in kernel-5.10 when "File Transfer" (MTP)
has been enabled by user.
Error log:
avc: denied { ioctl } for pid=5521 comm="MtpServer" path="/dev/usb-ffs/mtp/ep1" dev="functionfs" ino=102677 ioctlcmd=0x67e7 scontext=u:r:mediaprovider:s0:c512,c768 tcontext=u:object_r:functionfs:s0 tclass=file permissive=0
Repeat steps:
1. Connect the phone to PC with USB cable.
2. Select "File Transfer" (MTP) in "USB Preferences" Menu.
3. Selinux warning will arise after "File Transfer" has been enabled by user
due to an IOCTL access to /dev/usb-ffs/mtp/ep1.
Solution:
To solve this warning, add a sepolicy to allow this type of IOCTL is required.
