After the commit
02c763939c10 ("test/zdtm: unify common code")
CFLAGS with -D_GNU_SOURCE defined in the top Makefile
are being passed to tests Makefiles.
As _GNU_SOURCE is also defined by tests, that resulted in
zdtm tests build failures:
make[2]: Entering directory `/home/criu/test/zdtm/lib'
CC test.o
test.c:1:0: error: "_GNU_SOURCE" redefined [-Werror]
#define _GNU_SOURCE
^
<command-line>:0:0: note: this is the location of the previous definition
cc1: all warnings being treated as errors
make[2]: *** [test.o] Error 1
However, we didn't catch this in time by Travis-CI, as zdtm.py doesn't
do `make zdtm`, rather it does `make -C test/zdtm/{lib,static,transition}`.
By calling middle makefile this way, it doesn't have _GNU_SOURCE in
CFLAGS from top-Makefile.
I think the right thing to do here - is following CRIU's way:
rely on definition of _GNU_SOURCE by Makefiles.
This patch is almost fully generated with
find test/zdtm/ -name '*.c' -type f \
-exec sed -i '/define _GNU_SOURCE/{n;/^$/d;}' '{}' \; \
-exec sed -i '/define _GNU_SOURCE/d' '{}' \;
With an exception for adding -D_GNU_SOURCE in tests Makefile.inc for
keeping the same behaviour for zdtm.py.
Also changed utsname.c to use utsname::domainname, rather private
utsname::__domainname, as now it's uncovered (from sys/utsname.h):
> struct utsname
> {
...
> # ifdef __USE_GNU
> char domainname[_UTSNAME_DOMAIN_LENGTH];
> # else
> char __domainname[_UTSNAME_DOMAIN_LENGTH];
> # endif
