Backdoors

The company has seen embedding a backdoor in its version of the Linux kernel, which is offered for devices based on the Allwinner processors of the sun8i family (H3, A83T and H8). The backdoor allows you to obtain root privileges by writing the string "rootmydevice" to the file "/ proc / sunxi_debug / sunxi_debug". [four]

GPL Violation

Allwinner has been repeatedly reported violating the terms of the GPL . [five]

OpenBSD Support

In connection with porting OpenBSD to the ARMv7 architecture, it became possible to install this system on systems based on the Allwinner A1x / A20 family of chips. [6] The OpenBSD / armv7 project has existed since 2013. [7]

FreeBSD Support

The FreeBSD operating system is actively ported to different Allwinner processors. Currently supported: A10, A13, A20, A31, A31S, A64, A83T and H3 [8]
