License cleanup: add SPDX license identifier to uapi header files with no license Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does not cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does not fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

module: add flags arg to sys_finit_module() Thanks to Michael Kerrisk for keeping us honest. These flags are actually useful for eliminating the only case where kmod has to mangle a module's internals: for overriding module versioning.

module: add in-kernel support for decompressing Current scheme of having userspace decompress kernel modules before loading them into the kernel runs afoul of LoadPin security policy, as it loses link between the source of kernel module on the disk and binary blob that is being loaded into the kernel. To solve this issue let's implement decompression in kernel, so that we can pass a file descriptor of compressed module file into finit_module() which will keep LoadPin happy. To let userspace know what compression/decompression scheme kernel supports it will create /sys/module/compression attribute. kmod can read this attribute and decide if it can pass compressed file to finit_module(). New MODULE_INIT_COMPRESSED_DATA flag indicates that the kernel should attempt to decompress the data read from file descriptor prior to trying load the module. To simplify things kernel will only implement single decompression method matching compression method selected when generating modules. This patch implements gzip and xz; more can be added later, Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Luis Chamberlain <mcgrof@kernel.org> 2022-01-05 13:55:12 -08:00			`#define MODULE_INIT_COMPRESSED_FILE 4`
