From 353f71fe3c07fabc3433d94c894c0acdeadb2a29 Mon Sep 17 00:00:00 2001 From: Shuah Khan Date: Mon, 2 Oct 2017 16:16:13 -0600 Subject: [PATCH] selftests: x86: sysret_ss_attrs doesn't build on a PIE build commit 3346a6a4e5ba8c040360f753b26938cec31a4bdc upstream. sysret_ss_attrs fails to compile leading x86 test run to fail on systems configured to build using PIE by default. Add -no-pie fix it. Relocation might still fail if relocated above 4G. For now this change fixes the build and runs x86 tests. tools/testing/selftests/x86$ make gcc -m64 -o .../tools/testing/selftests/x86/single_step_syscall_64 -O2 -g -std=gnu99 -pthread -Wall single_step_syscall.c -lrt -ldl gcc -m64 -o .../tools/testing/selftests/x86/sysret_ss_attrs_64 -O2 -g -std=gnu99 -pthread -Wall sysret_ss_attrs.c thunks.S -lrt -ldl /usr/bin/ld: /tmp/ccS6pvIh.o: relocation R_X86_64_32S against `.text' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: Nonrepresentable section on output collect2: error: ld returned 1 exit status Makefile:49: recipe for target '.../tools/testing/selftests/x86/sysret_ss_attrs_64' failed make: *** [.../tools/testing/selftests/x86/sysret_ss_attrs_64] Error 1 Suggested-by: Andy Lutomirski Signed-off-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman --- tools/testing/selftests/x86/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/x86/Makefile b/tools/testing/selftests/x86/Makefile index 6eb50152baf0..e5b459a09cff 100644 --- a/tools/testing/selftests/x86/Makefile +++ b/tools/testing/selftests/x86/Makefile @@ -17,7 +17,7 @@ TARGETS_C_64BIT_ALL := $(TARGETS_C_BOTHBITS) $(TARGETS_C_64BIT_ONLY) BINARIES_32 := $(TARGETS_C_32BIT_ALL:%=%_32) BINARIES_64 := $(TARGETS_C_64BIT_ALL:%=%_64) -CFLAGS := -O2 -g -std=gnu99 -pthread -Wall +CFLAGS := -O2 -g -std=gnu99 -pthread -Wall -no-pie UNAME_M := $(shell uname -m) CAN_BUILD_I386 := $(shell ./check_cc.sh $(CC) trivial_32bit_program.c -m32) -- 2.20.1
