Events sent by Process Events Connector from a 64-bit kernel are not binary compatible with a 32-bit userspace program because the "timestamp" field (struct timespec) is not arch independent. This affects the fields that follow "timestamp" as they will be be off by 8 bytes. This is a problem for 32-bit userspace programs running with 64-bit kernels on ppc64, s390, x86-64.. any "biarch" system. Matt had submitted a different solution to lkml as an RFC earlier. We have since switched to a solution recommended by Evgeniy Polyakov. This patch fixes the problem by changing the timestamp to be a __u64, which stores the number of nanoseconds. Tested on a x86_64 system with both 32 bit application and 64 bit application and on a i386 system.
