upstream commit Make ssh_packet_set_rekey_limits take u32 for the number of seconds until rekeying (negative values are rejected at config parse time). This allows the removal of some casts and a signed vs unsigned comparison warning. rekey_time is cast to int64 for the comparison which is a no-op on OpenBSD, but should also do the right thing in -portable on anything still using 32bit time_t (until the system time actually wraps, anyway). some early guidance deraadt@, ok djm@ Upstream-ID: c9f18613afb994a07e7622eb326f49de3d123b6c
