Hi,
I'm trying to build arm64 selftests on next-20240529. I'm getting build failures. Complete logs are attached while some snippets are as following:
gcc pac.c /pauth/pac_corruptor.o /pauth/helper.o -o /pauth/pac -Wall -O2 -g -I/linux_mainline/tools/testing/selftests/ -I/linux_mainline/tools/include -mbranch-protection=pac-ret -march=armv8.2-a In file included from pac.c:13: ../../kselftest_harness.h: In function ‘clone3_vfork’: ../../kselftest_harness.h:88:9: error: variable ‘args’ has initializer but incomplete type 88 | struct clone_args args = {
CC check_prctl check_prctl.c: In function ‘set_tagged_addr_ctrl’: check_prctl.c:19:14: error: ‘PR_SET_TAGGED_ADDR_CTRL’ undeclared (first use in this function) 19 | ret = prctl(PR_SET_TAGGED_ADDR_CTRL, val, 0, 0, 0);
gcc -mbranch-protection=standard -DBTI=1 -ffreestanding -Wall -Wextra -Wall -O2 -g -I/linux_mainline/tools/testing/selftests/ -I/linux_mainline/tools/include -c -o /bti/test-bti.o test.c test.c: In function ‘handler’: test.c:85:50: error: ‘PSR_BTYPE_MASK’ undeclared (first use in this function); did you mean ‘PSR_MODE_MASK’? 85 | write(1, &"00011011"[((uc->uc_mcontext.pstate & PSR_BTYPE_MASK)
I've GCC 8 installed. I'm not expecting the errors because of a little older compiler. Any more ideas about the failures?

This is in the generic code.

You need to run headers_install IIRC.

You need to run headers_install IIRC.
I'm running: make headers && make -C tools/testing/selftests
I've tried gcc 12 as well.

It's your system headers (or not finding the kernel ones anyway) rather that the compiler. For PSR_BTYPE_MASK it's ptrace.h that's needed.
