216 265 * Check for time overflow using a kernel tunable to determine whether
217 266 * we should accept or reject an unsigned 32-bit time value. Time value in NFS
218 267 * v2/3 protocol is unsigned 32 bit, but ILP32 kernel only allows 31 bits.
219 268 * In nfsv4, time value is a signed 64 bit, so needs to be checked for
220 269 * overflow as well (e.g. for setattr). So define the tunable as follows:
221 270 * nfs_allow_preepoch_time is TRUE if pre-epoch (negative) times are allowed
222 271 * and is FALSE (the default) otherwise. For nfsv2/3 this means that
223 272 * if negative times are allowed, the uint32_t time value is interpreted
224 273 * as a signed int, otherwise as a large positive number. For nfsv4,
225 274 * we use the value as is - except that if negative times are not allowed,
226 275 * we will not accept a negative value otw.
227 276 *
228 277 * So for nfsv2/3 (uint32_t):
229 278 *
230 279 * If nfs_allow_preepoch_time is
231 280 * FALSE, the maximum time value is INT32_MAX for 32-bit kernels and
232 281 * UINT32_MAX for 64-bit kernels (to allow times larger than 2038)
233 282 * and the minimum is zero. Note that in that case, a 32-bit application
234 283 * running on a 64-bit kernel will not be able to access files with
235 284 * the larger time values.
236 285 * If nfs_allow_preepoch_time is TRUE, the maximum time value is INT32_MAX
237 286 * for both kernel configurations and the minimum is INT32_MIN.
238 287 *
239 288 * And for nfsv4 (int64_t):
240 289 *
241 290 * nfsv4 allows for negative values in the protocol, and has a 64-bit
242 291 * time field, so nfs_allow_preepoch_time can be ignored.
