Some distros have the pkey syscall numbers defined under unistd.h. This conflicts with the definitions in the pkeys selftest header and causes build failures. E.g. this works $ grep -nr "SYS_pkey" /usr/include/ /usr/include/bits/syscall.h:1575:# define SYS_pkey_alloc __NR_pkey_alloc /usr/include/bits/syscall.h:1579:# define SYS_pkey_free __NR_pkey_free /usr/include/bits/syscall.h:1583:# define SYS_pkey_mprotect __NR_pkey_mprotect While this does not $ grep -nr "SYS_pkey" /usr/include/ /usr/include/bits/syscall.h:1575:# define SYS_pkey_alloc __NR_pkey_alloc /usr/include/bits/syscall.h:1579:# define SYS_pkey_free __NR_pkey_free /usr/include/bits/syscall.h:1583:# define SYS_pkey_mprotect __NR_pkey_mprotect /usr/include/asm-generic/unistd.h:728:__SYSCALL(__NR_pkey_mprotect, sys_pkey_mprotect) /usr/include/asm-generic/unistd.h:730:__SYSCALL(__NR_pkey_alloc, sys_pkey_alloc) /usr/include/asm-generic/unistd.h:732:__SYSCALL(__NR_pkey_free, sys_pkey_free) Reported-by: Sachin Sant <sachinp@linux.vnet.ibm.com> Signed-off-by: Sandipan Das <sandipan@linux.ibm.com> --- tools/testing/selftests/powerpc/include/pkeys.h | 5 +++++ 1 file changed, 5 insertions(+)
