[PATCH] crypto: hisilicon/qm - Fix device reference leak in qm_get_qos_value

by Miaoqian Lin

The qm_get_qos_value() function calls bus_find_device_by_name() which increases the device reference count, but fails to call put_device() to balance the reference count and lead to a device reference leak. Add put_device() calls in both the error path and success path to properly balance the reference count. Found via static analysis.

And thus padded (correct Authenticode calculation) and unpadded calculation would be same. As in https://github.com/rhboot/pesign userspace tool would produce the same authenticode digest for both of the following commands: pesign --padding --hash --in ./arch/x86_64/boot/bzImage pesign --nopadding --hash --in ./arch/x86_64/boot/bzImage The commit 3e86e4d74c04 ("kbuild: keep .modinfo section in vmlinux.unstripped") added .modinfo section of variable length. Depending on kernel configuration it may or may not be aligned. All userspace signing tooling correctly pads such section to calculation spec compliant authenticode digest. However, if bzImage is not further processed and is attempted to be loaded directly by EDK2 firmware, it calculates unpadded Authenticode digest and fails to correct accept/reject such kernel builds even when propoer Authenticode values are enrolled in db/dbx. One can say EDK2 requires aligned/padded kernels in Secureboot. Thus add ALIGN(8) to the .modinfo section, to esure kernels irrespective of modinfo contents can be loaded by all existing EDK2 firmware builds.
