The problem is that the following upstream commits - a096ccca6e50 (\"tun: tun_chr_open(): correctly initialize socket uid\"), - 66b2c338adce (\"tap: tap_open(): correctly initialize socket uid\"), pass \"inode->i_uid\" to sock_init_data_uid() as the last parameter and that turns out to not be accurate."
