[kronosnet/kronosnet] 515f8d: Convert time_t to unsigned long long before format...

Branch: refs/heads/main Home: https://github.com/kronosnet/kronosnet Commit: 515f8d908083d1e83951442f0ccf40cdbfbde0e2 https://github.com/kronosnet/kronosnet/commit/515f8d908083d1e83951442f0ccf4… Author: Fabio M. Di Nitto <fdinitto(a)redhat.com> Date: 2024-07-31 (Wed, 31 Jul 2024) Changed paths: M libknet/links.c Log Message: ----------- Convert time_t to unsigned long long before formatting (#431) Conventionally it's signed long under the GNU C library, which is 32 bits on 32-bit architectures, but Glibc provides the __TIME_BITS==64 option, which makes it signed long long instead (64 bits) and makes no difference on 64-bit architectures [1]. Since the ping_interval and pong_timeout members of struct knet_link are unsigned, we can make this conversion safe by rejecting negative values as well (besides zero). In the end this enables using the uniform %llu conversion specifier across all supported architectures. This got exposed by Debian recently transitioning to 64-bit time_t [2].
