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.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

sh: include linux/time_types.h for sockios Using the socket ioctls on arch/sh (and only there) causes build time problems when __kernel_old_timeval/__kernel_old_timespec are not already visible to the compiler. Add an explict include line for the header that defines these structures.

y2038: sh: remove timeval/timespec usage from headers This header file escaped my earlier cleanups for removing the in-kernel usage of timeval and timespec structs. Replace them with the corresponding __kernel_old_* types.

net: socket: implement 64-bit timestamps The 'timeval' and 'timespec' data structures used for socket timestamps are going to be redefined in user space based on 64-bit time_t in future versions of the C library to deal with the y2038 overflow problem, which breaks the ABI definition. Unlike many modern ioctl commands, SIOCGSTAMP and SIOCGSTAMPNS do not use the _IOR() macro to encode the size of the transferred data, so it remains ambiguous whether the application uses the old or new layout. The best workaround I could find is rather ugly: we redefine the command code based on the size of the respective data structure with a ternary operator. This lets it get evaluated as late as possible, hopefully after that structure is visible to the caller. We cannot use an #ifdef here, because inux/sockios.h might have been included before any libc header that could determine the size of time_t. The ioctl implementation now interprets the new command codes as always referring to the 64-bit structure on all architectures, while the old architecture specific command code still refers to the old architecture specific layout. The new command number is only used when they are actually different. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net> 2019-04-17 22:56:11 +02:00
