[PATCH] fs:affs:Replace time_t with time64_t

by DengChao

The affs code uses "time_t" and "get_seconds()". This will cause problems on 32-bit architectures in 2038 when time_t overflows. This patch replaces them with "time64_t" and "ktime_get_real_seconds()". This patch introduces expensive 64-bit divsion in "secs_to_datestamp()", considering this function is not called so often, the cost should be acceptable.

[PATCH V1] serial:bfin-uart:Remove 'struct timeval'

by DengChao

The bfin-uart code uses real time with struct timeval. This will cause problems on 32-bit architectures in 2038 when time_t overflows. Since the code just needs delta value of time, it is not necessary to record them in real time. This patch changes the code to use the monotonic time instead, replaces struct timeval and do_gettimeofday() with u64 and ktime_get_ns().

[PATCH v3 0/2] Convert ppdev to y2038 safe

by Bamvor Jian Zhang

Here is the third version for converting parport device(ppdev) to y2038 safe. The first two version could found at [1],[2]. An y2038 safe application/kernel use 64bit time_t(aka time64_t) instead of 32bit time_t. There are the 5 cases need to support: summary |u:arch |u:tv_sec |k:arch |k:tv_sec -------------------|-------|---------|-------|-------- 32_y2038_unsafe |32 |32 |32 |32 32_y2038_safe |32 |64 |32 |64 compat_y2038_unsafe|32 |32 |64 |64 compat_y2038_safe |32 |64 |64 |64 64_y2038_safe |64 |64 |64 |64 notes: 1. xxx_y2038_safe/unsafe. 32 means app running on the 32bit kernel. compat means 32bit app running on 64bit kernel. 64 means 64bit app running on 64bit kernel. 2. 1.3.5 are the original one, we need keep the compatability. 2,4 is new one we need to support. There are different ways to do this. Convert to 64bit time and/or define COMPAT_USE_64BIT_TIME 0 or 1 to indicate y2038 safe or unsafe. But it is not mean that we need to convert all the time relative struct to 64bit. Because some time relative struct(e.g. timeval in ppdev.c) is mainly the offset of the real time. The main issue in ppdev.c is PPSETTIME/PPGETTIME which transfer timeval between user space and kernel. My approach here is handle them as different ioctl command. Build successful on arm64 and arm.

[PATCH v2 0/9] [media] y2038 conversion for subsystem

by Arnd Bergmann

This is my second attempt to convert subsystem-wide code in v4l for y2038 changes, removing uses of time_t in common files and adding support for user space that defines time_t as 64 bit. Based on the initial feedback from Hans Verkuil, I've changed the ioctl handling to remain 100% compatible with existing headers, which also makes it more likely that existing source code can compile without changes. This comes at a noticeable expense of adding complexity to the v4l2-ioctl.c file, as we now have to handle two versions of each ioctl command that passes a time_t in its arguments. I have not added support for the new binary layout of v4l2_timeval to v4l2-compat-ioctl32 yet, that is something I can do when the basic approach has been agreed on.

[PATCH 0/3] fix y2038 problem in input_event

by WEN Pingbo

Before this, I have discussed this problem with Arnd. And Arnd have an idea that by converting timeval to long / long in input_event, so that input_event structure size will be unchanged, and timeval structure will removed entirely. But we also need to avoid using CLOCK_REALTIME in userland, to keep the new input_event structure y2038 safe. The input_event will only support monotonic time in Arnd's idea. And we still need to add wall time support for old 32-bit binary. Those patches try to keep original input capacity, and resolve y2038 problem in input_event radically. struct input_event is only used between kernel and userspace communication (except uinput). So that we can replace input_event with input_event64 in kernel entirely, and add a conversion in input_event_from/to_user() to keep compatible with old 32-bits binary. userland can switch to input_event64, which is y2038 safe, via ioctl.
