[PATCH] bnx2x: use ktime_get_seconds() for timestamp

by Arnd Bergmann

commit c48f350ff5e7 "bnx2x: Add MFW dump support" added the bnx2x_update_mfw_dump() function that reads the current time and stores it in a 32-bit field that gets passed into a buffer in a fixed format. This is potentially broken when the epoch overflows in 2038, and otherwise overflows in 2106. As we're trying to avoid uses of struct timeval for this reason, I noticed the addition of this function, and tried to rewrite it in a way that is more explicit about the overflow and that will keep working once we deprecate struct timeval. I assume that it is not possible to change the ABI any more, otherwise we should try to use a 64-bit field for the seconds right away.

[PATCH v2 0/5] Introduce 64bit accessors and structures required to address y2038 issues in the posix_clock subsystem

by Baolin Wang

This patch series change the 32-bit time types (timespec/itimerspec) to the 64-bit types (timespec64/itimerspec64), and add new 64bit accessor functions, which are required in order to avoid y2038 issues in the posix_clock subsystem. In order to avoid spamming people too much, I'm only sending the first few patches of the patch series, and left the other patches for later. And if you are interested in the whole patch series, see: https://git.linaro.org/people/baolin.wang/upstream_0627.git Thoughts and feedback would be appreciated. Changes since v1: - Modify the changelog. - Delete one patch without y2038 safe.

[RFD PATCH 0/2] Convert sound subsystem to year 2038 safe

by Bamvor Zhang Jian

This is my first attempt to convert sound subsystem to year 2038 safe. In these series patches I focus on the timer. When check the time relative code in timer of sound subsystem, I feel that I could easy split 64bit time_xxx type in kernel and in userspace (__kernel_time_xxx) according to arnd's approach[1] in comparison with other parts of sound subsys(e.g. pcm). Whether I should follow the same approach in the whole sound subsystem is an open issue for me. On the other hand, there are difference approaches for dealing with the code in userspace. It seems that snd_timer_read is the only api for other parts of alsa. It share the same code no matter tread is true or false. The fisrt approach is hide __kernel_time_xxx inside snd_timer_read, although the code may be a little bit ugly. The second approach is that force userspace migration to 64bit time on all 32bit(including compat) system by re-definition the following types in alsa-lib/include/global.h: typedef struct __kernel_timespec snd_htimestamp_t; This approach will not affect the 64bit application.
