This patch fixes a race condition in the --atime-preserve=replace option, which might cause tar to improperly follow a symbolic link. It also drops the use of the _FIOSATIME ioctl of Solaris 2.x and later, which loses resolution on time stamps. Modern Solaris systems support full-resolution time stamps in the kernel, and it's not worth the hassle of testing this call, useful only in no-longer-supported Solaris variants. Also, it undoes a change I recently introduced to the --compare option, which caused it to not follow symbolic links unless the --dereference option was also used. Quite possibly this change is a good idea, but the old behavior was documented and the change should not have been installed casually. * configure.ac: Don't check for stropts.h and sys/filio.h. * gnulib.modules: Add futimens, utimensat. Remove futimens. * src/common.h (fd_utimensat): New decl. * src/compare.c (diff_file, diff_multivol): Don't use open_read_flags: those are for --create only. * src/create.c (dump_file0): Adjust to set_file_atime changes. Pass fstatat_flags to set_file_atime, so that symbolic links are not followed inadvertantly. * src/extract.c: Don't include utimens.h. (set_stat): Use fd_utimensat ant UTIME_NOW rather than fdutimens. * src/misc.c: Don't include utimens.h, stropts.h, sys/filio.h. (fd_utimensat): New function. (set_file_atime): Use it. New arg atflag, controlling symlink handling. All callers changed.
