[PATCH v4] Staging: olpc_dcon: Replace timespec with ktime_t

by Ksenija Stanojevic

Struct timespec will overflow in year 2038, here it will not cause an overflow because it is used with timespec_sub, but still has to be removed as part of y2038 changes. Replace it with ktime_t. Also use monotonic instead of real-time by replacing functions getnstimeofday with ktime_get.

[PATCH 0/5] y2038 conversion for ntp/pps and sfc driver

by Arnd Bergmann

When trying to build a kernel with time_t commented out, I found that the ntp subsystem still relies on timespec for its pps handling. This series addresses this and converts all the code to use timespec64 instead, step by step. There is one device driver that interacts with this code directly (rather than only through the ptp subsystem), so I have to convert that driver at the same time. The patches should ideally stay together as a series, but they do span multiple subsystems, so I'm also looking for the right person to merge them. Please review. Thanks, Arnd Arnd Bergmann (5): ntp/pps: use timespec64 for hardpps() ntp/pps: replace getnstime_raw_and_real with 64-bit version ntp: use timespec64 in sync_cmos_clock ntp/pps: use y2038 safe types in pps_event_time net: sfc: avoid using timespec drivers/net/ethernet/sfc/ptp.c | 30 +++++++++++++++--------------- drivers/pps/kapi.c | 4 ++-- include/linux/pps_kernel.h | 16 ++++++++-------- include/linux/timekeeping.h | 4 ++-- include/linux/timex.h | 2 +- kernel/time/ntp.c | 16 ++++++++-------- kernel/time/ntp_internal.h | 2 +- kernel/time/timekeeping.c | 14 +++++++------- 8 files changed, 44 insertions(+), 44 deletions(-) -- 2.1.0.rc2

[PATCH] ceph: fix message length computation

by Arnd Bergmann

create_request_message() computes the maximum length of a message, but uses the wrong type for the time stamp: sizeof(struct timespec) may be 8 or 16 depending on the architecture, while sizeof(struct ceph_timespec) is always 8, and that is what gets put into the message. Found while auditing the uses of timespec for y2038 problems.
