From b2aa820b48add74b97e0eab993ede648c43e85db Mon Sep 17 00:00:00 2001 From: Yousong Zhou Date: Thu, 9 Nov 2017 17:29:56 +0800 Subject: [PATCH] base-files: fix getting gid from group_add_next Shell function return code only has range [0, 255]. Other values will be truncated, e.g. return 65536 will have the same effect as return 0 While at it, drop other "return $rc" where rc will almost always take value 0 and whose value current callers actually do not check Fixes FS#988 Signed-off-by: Yousong Zhou --- package/base-files/Makefile | 2 +- package/base-files/files/lib/functions.sh | 13 ++++++------- 2 files changed, 7 insertions(+), 8 deletions(-) diff --git a/package/base-files/Makefile b/package/base-files/Makefile index e6c53e95a4..077bed469d 100644 --- a/package/base-files/Makefile +++ b/package/base-files/Makefile @@ -11,7 +11,7 @@ include $(INCLUDE_DIR)/kernel.mk include $(INCLUDE_DIR)/version.mk PKG_NAME:=base-files -PKG_RELEASE:=177 +PKG_RELEASE:=178 PKG_FLAGS:=nonshared PKG_FILE_DEPENDS:=$(PLATFORM_DIR)/ $(GENERIC_PLATFORM_DIR)/base-files/ diff --git a/package/base-files/files/lib/functions.sh b/package/base-files/files/lib/functions.sh index 4879a3708a..dfadfdb2d9 100755 --- a/package/base-files/files/lib/functions.sh +++ b/package/base-files/files/lib/functions.sh @@ -202,7 +202,7 @@ add_group_and_user() { if [ -n "$gname" ] && [ -n "$gid" ]; then group_exists "$gname" || group_add "$gname" "$gid" elif [ -n "$gname" ]; then - group_add_next "$gname"; gid=$? + gid="$(group_add_next "$gname")" fi if [ -n "$uname" ]; then @@ -296,9 +296,7 @@ group_add() { [ -f "${IPKG_INSTROOT}/etc/group" ] || return 1 [ -n "$IPKG_INSTROOT" ] || lock /var/lock/group echo "${name}:x:${gid}:" >> ${IPKG_INSTROOT}/etc/group - rc=$?
