216 216 * Check for time overflow using a kernel tunable to determine whether

218 218 * v2/3 protocol is unsigned 32 bit, but ILP32 kernel only allows 31 bits.
219 219 * In nfsv4, time value is a signed 64 bit, so needs to be checked for
220 220 * overflow as well (e.g. for setattr). So define the tunable as follows:
221 221 * nfs_allow_preepoch_time is TRUE if pre-epoch (negative) times are allowed
222 222 * and is FALSE (the default) otherwise. For nfsv2/3 this means that
223 223 * if negative times are allowed, the uint32_t time value is interpreted
224 224 * as a signed int, otherwise as a large positive number. For nfsv4,
225 225 * we use the value as is - except that if negative times are not allowed,
226 226 * we will not accept a negative value otw.
227 227 *
228 228 * So for nfsv2/3 (uint32_t):
229 229 *
230 230 * If nfs_allow_preepoch_time is
231 231 * FALSE, the maximum time value is INT32_MAX for 32-bit kernels and
232 232 * UINT32_MAX for 64-bit kernels (to allow times larger than 2038)
233 233 * and the minimum is zero. Note that in that case, a 32-bit application
234 234 * running on a 64-bit kernel will not be able to access files with
235 235 * the larger time values.
236 236 * If nfs_allow_preepoch_time is TRUE, the maximum time value is INT32_MAX
237 237 * for both kernel configurations and the minimum is INT32_MIN.
238 238 *
239 239 * And for nfsv4 (int64_t):
240 240 *
241 241 * nfsv4 allows for negative values in the protocol, and has a 64-bit
242 242 * time field, so nfs_allow_preepoch_time can be ignored.
