--- Begin Message ---Package: libc6 Version: 2.37-6 Tags: upstream The utmp(5) interface has broken its compatibility in 32-bit programs built with -D_TIME_BITS=64. In bits/utmpx.h we see this: ,---- | /* The fields ut_session and ut_tv must be the same size when compiled | 32- and 64-bit. This allows files and shared memory to be shared | between 32- and 64-bit applications. */ | #if __WORDSIZE_TIME64_COMPAT32 | __int32_t ut_session; /* Session ID, used for windowing. */ | struct | { | __int32_t tv_sec; /* Seconds. */ | __int32_t tv_usec; /* Microseconds. */ | } ut_tv; /* Time entry was made. */ | #else | long int ut_session; /* Session ID, used for windowing. */ | struct timeval ut_tv; /* Time entry was made. */ | #endif `---- The definition of __WORDSIZE_TIME64_COMPAT32 can be found in bits/wordsize.h: ,---- | #ifdef __x86_64__ | # define __WORDSIZE_TIME64_COMPAT32 1 | /* Both x86-64 and x32 use the 64-bit system call interface. */ | # define __SYSCALL_WORDSIZE 64 | #else | # define __WORDSIZE_TIME64_COMPAT32 0 | #endif `---- So on i386 (and I suppose on other 32-bit architectures except x32) ut_tv is of struct timeval, and ut_tv.tv_sec is of time_t, which is actually a 64-bit integer in programs built with -D_TIME_BITS=64. One example where this already has caused problems is the who(1) program which has opted in for -D_TIME_BITS=64, see #1027135. Once programs start to _write_ utmp entries with a 64-bit ut_tv.tv_sec rather than merely reading them, things could become more interesting. :-( -- System Information: Debian Release: trixie/sid APT prefers unstable APT policy: (500, 'unstable'), (101, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386
