tty: Partially revert the removal of the Cyclades public API

2022-01-26T13:49:46+00:00

Fix a user API regression introduced with commit f76edd8f7ce0 ("tty: cyclades, remove this orphan"), which removed a part of the API and caused compilation errors for user programs using said part, such as GCC 9 in its libsanitizer component[1]: .../libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc:160:10: fatal error: linux/cyclades.h: No such file or directory 160 | #include | ^~~~~~~~~~~~~~~~~~ compilation terminated. make[4]: *** [Makefile:664: sanitizer_platform_limits_posix.lo] Error 1 As the absolute minimum required bring `struct cyclades_monitor' and ioctl numbers back then so as to make the library build again. Add a preprocessor warning as to the obsolescence of the features provided.

tty: cyclades, remove this orphan

2021-03-10T08:34:06+00:00

The Cyclades driver was orphaned by commit d459883e6c54 (MAINTAINERS: remove two dead e-mail) 13 years ago. Noone stepped up to take care of them and to fix all the issues the driver has. On the top of that, there is no way to obtain the firmware for Z cards from the vendor as cyclades.com ceased to exist. So it's time to drop the driver with all its traces.

y2038: uapi: change __kernel_time_t to __kernel_old_time_t

2019-11-15T13:38:29+00:00

This is mainly a patch for clarification, and to let us remove the time_t definition from the kernel to prevent new users from creeping in that might not be y2038-safe. All remaining uses of 'time_t' or '__kernel_time_t' are part of the user API that cannot be changed by that either have a replacement or that do not suffer from the y2038 overflow.

License cleanup: add SPDX license identifier to uapi header files with no license

2017-11-02T10:19:54+00:00

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.
