File util-linux-uuidd-prevent-root-owning.patch of Package util-linux.26137
Prevent root owning of /var/lib/libuuid/clock.txt Just after the installation, calling uuid_generate_time() or uuid_generate_time_safe() as root may create root owned /var/lib/libuuid/clock.txt, which makes it unusable for uuidd. To reproduce: zypper rm uuidd zypper in uuidd uuidgen --time ls -l /var/lib/libuuid/clock.txt rcuuidd start ls -l /var/lib/libuuid/clock.txt Before: -rw-rw---- 1 root root 56 Mar 4 17:24 /var/lib/libuuid/clock.txt After (with the patch): -rw-rw---- 1 uuidd uuidd 56 Mar 4 17:30 /var/lib/libuuid/clock.txt Index: util-linux-2.36.2/misc-utils/uuidd.service.in =================================================================== --- util-linux-2.36.2.orig/misc-utils/uuidd.service.in +++ util-linux-2.36.2/misc-utils/uuidd.service.in @@ -4,6 +4,7 @@ Documentation=man:uuidd(8) Requires=uuidd.socket [Service] +ExecStartPre=+-@CHOWN@ uuidd:uuidd /var/lib/libuuid/clock.txt ExecStart=@usrsbin_execdir@/uuidd --socket-activation Restart=no User=uuidd Index: util-linux-2.36.2/configure.ac =================================================================== --- util-linux-2.36.2.orig/configure.ac +++ util-linux-2.36.2/configure.ac @@ -168,6 +168,8 @@ AC_SUBST([PYTHON_WARN_CFLAGS]) UL_WARN_ADD([-Wno-unused-parameter], [NO_UNUSED_WARN_CFLAGS]) AC_SUBST([NO_UNUSED_WARN_CFLAGS]) +AC_PATH_PROG([CHOWN], [chown]) + AC_ARG_ENABLE([asan], AS_HELP_STRING([--enable-asan], [compile with Address Sanitizer]), Index: util-linux-2.36.2/Makefile.am =================================================================== --- util-linux-2.36.2.orig/Makefile.am +++ util-linux-2.36.2/Makefile.am @@ -131,6 +131,7 @@ edit_cmd = sed \ -e 's|@usrsbin_execdir[@]|$(usrsbin_execdir)|g' \ -e 's|@VERSION[@]|$(VERSION)|g' \ -e 's|@ADJTIME_PATH[@]|$(ADJTIME_PATH)|g' \ + -e 's|@CHOWN[@]|$(CHOWN)|g' \ -e 's|@LIBUUID_VERSION[@]|$(LIBUUID_VERSION)|g' \ -e 's|@LIBMOUNT_VERSION[@]|$(LIBMOUNT_VERSION)|g' \ -e 's|@LIBMOUNT_MAJOR_VERSION[@]|$(LIBMOUNT_MAJOR_VERSION)|g' \
