>From 7b250ae334fd8d6b15468c6ea3e068b4eb962ea1 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 1 Aug 2019 21:33:57 -0400 Subject: [PATCH 04/17] make fstatat fill in old time32 stat fields too here _REDIR_TIME64 is used as an indication that there's an old ABI, and thereby the old time32 timespec fields of struct stat. keeping struct stat compatible and providing both versions of the timespec fields is done so that ftw/nftw does not need painful compat shims, and (more importantly) so that similar interfaces between pairs of libc consumers (applications/libraries) will be less likely to break when one has been rebuilt for time64 but the other has not. --- src/stat/fstatat.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/src/stat/fstatat.c b/src/stat/fstatat.c index bf0a554c..de165b5c 100644 --- a/src/stat/fstatat.c +++ b/src/stat/fstatat.c @@ -57,6 +57,14 @@ static int fstatat_statx(int fd, const char *restrict path, struct stat *restric .st_mtim.tv_nsec = stx.stx_mtime.tv_nsec, .st_ctim.tv_sec = stx.stx_ctime.tv_sec, .st_ctim.tv_nsec = stx.stx_ctime.tv_nsec, +#if _REDIR_TIME64 + .__st_atim32.tv_sec = stx.stx_atime.tv_sec, + .__st_atim32.tv_nsec = stx.stx_atime.tv_nsec, + .__st_mtim32.tv_sec = stx.stx_mtime.tv_sec, + .__st_mtim32.tv_nsec = stx.stx_mtime.tv_nsec, + .__st_ctim32.tv_sec = stx.stx_ctime.tv_sec, + .__st_ctim32.tv_nsec = stx.stx_ctime.tv_nsec, +#endif }; return 0; } @@ -110,6 +118,14 @@ static int fstatat_kstat(int fd, const char *restrict path, struct stat *restric .st_mtim.tv_nsec = kst.st_mtime_nsec, .st_ctim.tv_sec = kst.st_ctime_sec, .st_ctim.tv_nsec = kst.st_ctime_nsec, +#if _REDIR_TIME64 + .__st_atim32.tv_sec = kst.st_atime_sec, + .__st_atim32.tv_nsec = kst.st_atime_nsec, + .__st_mtim32.tv_sec = kst.st_mtime_sec, + .__st_mtim32.tv_nsec = kst.st_mtime_nsec, + .__st_ctim32.tv_sec = kst.st_ctime_sec, + .__st_ctim32.tv_nsec = kst.st_ctime_nsec, +#endif }; return 0; -- 2.21.0
