WORM-Xlator: Maybe integer overflow when computing new atime
The structs worm_reten_state_t and read_only_priv_t from read-only.h are
using uint64_t values to store periods of retention and autocommmit.
This seems to be dangerous since in worm-helper.c the function
worm_set_state computes in line 97:
stbuf->ia_atime = time(NULL) + retention_state->ret_period;
stbuf->ia_atime is using int64_t because of the settings of struct
iattr. So if there is a very very high retention period stored, there
is maybe an integer overflow.
What can be the solution? Using int64_t instead if uint64_t may reduce
the probability of the occurance.
