This will not cause an error if the symlink points to an +existent file. But under some special situation, such as installing +a rpm package, rpm tool will create the symlink first and try to +modify the timestamps of it, when the target file is non-existent. +This will cause an ESTALE error. Making rpm tool ignore this error +is a solution, but not the best one. An acceptable approach is +Making unfs3 support lutimes(), which can modify the symlink file +itself. Considering not every system support this function, so a +function checking is necessary. + +Upstream-Status: Submitted [https://sourceforge.net/p/unfs3/bugs/12/] + +Signed-off-by: Rui Wang <rui.wang@windriver.com> +--- + attr.c | 15 +++++++++++---- + backend_unix.h | 2 ++ + configure.ac | 1 + + 3 files changed, 14 insertions(+), 4 deletions(-) + +diff --git a/attr.c b/attr.c +index 73e5c75..427d0e2 100644 +--- a/attr.c ++++ b/attr.c +@@ -280,7 +280,7 @@ post_op_attr get_post_cached(struct svc_req * req) + static nfsstat3 set_time(const char *path, backend_statstruct buf, sattr3 new) + { + time_t new_atime, new_mtime; +- struct utimbuf utim; ++ struct timeval stamps[2]; + int res; + + /* set atime and mtime */ +@@ -302,10 +302,17 @@ static nfsstat3 set_time(const char *path, backend_statstruct buf, sattr3 new) + else /* DONT_CHANGE */ + new_mtime = buf.st_mtime; + +- utim.actime = new_atime; +- utim.modtime = new_mtime; ++ stamps[0].tv_sec = new_atime; ++ stamps[0].tv_usec = 0; ++ stamps[1].tv_sec = new_mtime; ++ stamps[1].tv_usec = 0; ++ ++#if HAVE_LUTIMES ++ res = backend_lutimes(path, stamps); ++#else ++ res = backend_utimes(path, stamps); ++#endif + +- res = backend_utime(path, &utim); + if (res == -1) + return setattr_err(); + } +diff --git a/backend_unix.h b/backend_unix.h +index fbc2af3..813ffd3 100644 +--- a/backend_unix.h ++++ b/backend_unix.h +@@ -61,6 +61,8 @@ + #define backend_symlink symlink + #define backend_truncate truncate + #define backend_utime utime ++#define backend_utimes utimes ++#define backend_lutimes lutimes + #define backend_statstruct struct stat + #define backend_dirstream DIR + #define backend_statvfsstruct struct statvfs +diff --git a/configure.ac b/configure.ac +index aeec598..ea7f167 100644 +--- a/configure.ac ++++ b/configure.ac +@@ -37,6 +37,7 @@ AC_CHECK_FUNCS(setresuid setresgid) + AC_CHECK_FUNCS(vsyslog) + AC_CHECK_FUNCS(lchown) + AC_CHECK_FUNCS(setgroups) ++AC_CHECK_FUNCS(lutimes) + UNFS3_SOLARIS_RPC + UNFS3_PORTMAP_DEFINE + UNFS3_COMPILE_WARNINGS |
