    security: keys: Replace time_t/timespec with time64_t · 074d5898
    Baolin Wang authored
    The 'struct key' will use 'time_t' which we try to remove in the
    kernel, since 'time_t' is not year 2038 safe on 32bit systems.
    Also the 'struct keyring_search_context' will use 'timespec' type
    to record current time, which is also not year 2038 safe on 32bit
    Thus this patch replaces 'time_t' with 'time64_t' which is year 2038
    safe for 'struct key', and replace 'timespec' with 'time64_t' for the
    'struct keyring_search_context', since we only look at the the seconds
    part of 'timespec' variable. Moreover we also change the codes where
    using the 'time_t' and 'timespec', and we can get current time by
    ktime_get_real_seconds() instead of current_kernel_time(), and use
    'TIME64_MAX' macro to initialize the 'time64_t' type variable.
    Especially in proc.c file, we have replaced 'unsigned long' and 'timespec'
    type with 'u64' and 'time64_t' type to save the timeout value, which means
    user will get one 'u64' type timeout value by issuing proc_keys_show()
