Status for kronosnet/1.29-1

Patch Description Author Forwarded Bugs Origin Last update
Convert-time_t-to-unsigned-long-long-before-formatting.patch Convert time_t to unsigned long long before formatting
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].
