[PATCH 00/23] y2038 cleanups

by Arnd Bergmann

This is a series of cleanups for the y2038 work, mostly intended for namespace cleaning: the kernel defines the traditional time_t, timeval and timespec types that often lead to y2038-unsafe code. Even though the unsafe usage is mostly gone from the kernel, having the types and associated functions around means that we can still grow new users, and that we may be missing conversions to safe types that actually matter. As there is no rush on any of these patches, I would either queue them up in linux-next through my y2038 branch, or Thomas could add them to the tip tree if he wants. As mentioned in another series, this is part of a larger effort to fix all the remaining bits and pieces that are not completed yet from the y2038 conversion, and the full set can be found at: https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=… Maintainers, please review and provide Acks. Let me know if you have any opinion on whether we should do the include last two patches of this series or not. Arnd Arnd Bergmann (23): y2038: remove CONFIG_64BIT_TIME y2038: add __kernel_old_timespec and __kernel_old_time_t y2038: vdso: change timeval to __kernel_old_timeval y2038: vdso: change timespec to __kernel_old_timespec y2038: vdso: change time_t to __kernel_old_time_t y2038: vdso: nds32: open-code timespec_add_ns() y2038: vdso: powerpc: avoid timespec references y2038: ipc: remove __kernel_time_t reference from headers y2038: stat: avoid 'time_t' in 'struct stat' y2038: uapi: change __kernel_time_t to __kernel_old_time_t y2038: rusage: use __kernel_old_timeval y2038: syscalls: change remaining timeval to __kernel_old_timeval y2038: socket: remove timespec reference in timestamping y2038: make ns_to_compat_timeval use __kernel_old_timeval y2038: elfcore: Use __kernel_old_timeval for process times y2038: timerfd: Use timespec64 internally y2038: time: avoid timespec usage in settimeofday() y2038: itimer: compat handling to itimer.c y2038: use

[GIT PULL] compat_ioctl: remove most of fs/compat_ioctl.c

by Arnd Bergmann

The following changes since commit da0c9ea146cbe92b832f1b0f694840ea8eb33cce: Linux 5.4-rc2 (2019-10-06 14:27:30 -0700) are available in the Git repository at: git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground.git tags/compat-ioctl-5.5 for you to fetch changes up to 142b2ac82e31c174936c5719fa12ae28f51a55b7: scsi: sd: enable compat ioctls for sed-opal (2019-10-23 17:23:47 +0200) ---------------------------------------------------------------- compat_ioctl: remove most of fs/compat_ioctl.c As part of the cleanup of some remaining y2038 issues, I came to fs/compat_ioctl.c, which still has a couple of commands that need support for time64_t. In completely unrelated work, I spent time on cleaning up parts of this file in the past, moving things out into drivers instead. After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers. This series incorporates some of Al's work and many patches of my own, but in the end stops short of actually removing the last part, which is the scsi ioctl handlers. I have patches for those as well, but they need more testing or possibly a rewrite.
