[PATCH v6 0/8] y2038 safety in v4l2

by Arnd Bergmann

I'm in the process of finishing up the last bits on y2038-unsafe code in the kernel, this series is for v4l2, which has no problem with overflow, but has multiple ioctls that break with user space built against a new 32-bit libc. I posted similar patches as part of a series back in 2015, the new version was rewritten from scratch and I double-checked with the old version to make sure I did not miss anything I had already taken care of before. Hans Verkuil worked on a different patch set in 2017, but this also did not get to the point of being merged. My new version contains compat-ioctl support, which the old one did not and should be complete, but given its size likely contains bugs. I did randconfig build tests, but no runtime test, so careful review as well as testing would be much appreciated. With this version, the newly added code takes care of the existing ABI, while the existing code got moved to the 64-bit time_t interface and is used internally. This means that testing with existing binaries should exercise most of the modifications and if that works and doesn't get shot down in review, we can probably live without testing the new ABI explicitly. I'm not entirely happy with the compat-ioctl implementation that adds quite a bit of code duplication, but I hope this is acceptable anyway, as a better implementation would likely require a larger refactoring of the compat-ioctl file, while my approach simply adds support for the additional data structure variants. I uploaded git branch on top of the v4l2/dvb branch to [2]. Arnd Changes since v5: - Fix all bugs that Hans found during testing - Add a comment about x32 still being broken Changes since v4: - Move non-public contents out of uapi header - split out __kernel_v4l2_timeval into separate struct - use compound initializers for v4l2_event_time32 and v4l2_buffer_time32 conversion - add comment for v4l2_buffer_get_timestamp() Changes since v3: - This is a minor update compared to version 3 of this series, with bugfixes for small mistakes that I found or that were reported by automated build bots.

[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

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.
