From 5f161b2398fc610ebcc65591155faacfa32a2e03 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Thu, 16 May 2019 20:03:39 +0000 Subject: [PATCH] Update kernel-features.h files for Linux 5.1. Linux 5.1 adds missing syscalls to the syscall table for many Linux kernel architectures. This patch updates the kernel-features.h headers accordingly. __ASSUME_DIRECT_SYSVIPC_SYSCALLS is not updated because of the differences between new and old syscalls described in . The statfs64 structure used by alpha matches what the new kernel syscalls use. Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/alpha/kernel-features.h (__ASSUME_STATFS64): Only undefine if [__LINUX_KERNEL_VERSION < 0x050100]. * sysdeps/unix/sysv/linux/ia64/kernel-features.h (__ASSUME_STATX): Likewise. * sysdeps/unix/sysv/linux/sh/kernel-features.h (__ASSUME_STATX): Likewise. --- ChangeLog | 10 ++++++++++ sysdeps/unix/sysv/linux/alpha/kernel-features.h | 8 +++++--- sysdeps/unix/sysv/linux/ia64/kernel-features.h | 6 ++++-- sysdeps/unix/sysv/linux/sh/kernel-features.h | 6 ++++-- 4 files changed, 23 insertions(+), 7 deletions(-) diff --git a/ChangeLog b/ChangeLog index cb020262d9..a46b64ffb5 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,13 @@ +2019-05-16 Joseph Myers + + * sysdeps/unix/sysv/linux/alpha/kernel-features.h + (__ASSUME_STATFS64): Only undefine if [__LINUX_KERNEL_VERSION < + 0x050100]. + * sysdeps/unix/sysv/linux/ia64/kernel-features.h (__ASSUME_STATX): + Likewise. + * sysdeps/unix/sysv/linux/sh/kernel-features.h + (__ASSUME_STATX): Likewise. + 2019-05-16 Florian Weimer * nis/nss_nis/nis-hosts.c (EXTRA_ARGS, EXTRA_ARGS_DECL): Remove diff --git a/sysdeps/unix/sysv/linux/alpha/kernel-features.h b/sysdeps/unix/sysv/linux/alpha/kernel-features.h index f3298b234e..4a5d029c1d 100644 --- a/sysdeps/unix/sysv/linux/alpha/kernel-features.h +++ b/sysdeps/unix/sysv/linux/alpha/kernel-features.h @@ -22,9 +22,11 @@ #include_next -/* There never has been support for fstat64. */ -#undef __ASSUME_STATFS64 -#define __ASSUME_STATFS64 0 +/* Support for statfs64 was added in 5.1. */ +#if __LINUX_KERNEL_VERSION < 0x050100 +# undef __ASSUME_STATFS64 +# define __ASSUME_STATFS64 0 +#endif /* Alpha used to define SysV ipc shmat syscall with a different name. */ #ifndef __NR_shmat diff --git a/sysdeps/unix/sysv/linux/ia64/kernel-features.h b/sysdeps/unix/sysv/linux/ia64/kernel-features.h index 0f4948b8e0..333947931d 100644 --- a/sysdeps/unix/sysv/linux/ia64/kernel-features.h +++ b/sysdeps/unix/sysv/linux/ia64/kernel-features.h @@ -26,8 +26,10 @@ #define __ASSUME_SEND_SYSCALL 1 #define __ASSUME_ACCEPT4_SYSCALL 1 -/* No statx system call on ia64 yet. */ -#undef __ASSUME_STATX +/* Support for statx was added in 5.1. */ +#if __LINUX_KERNEL_VERSION < 0x050100 +# undef __ASSUME_STATX +#endif #undef __ASSUME_CLONE_DEFAULT #define __ASSUME_CLONE2 diff --git a/sysdeps/unix/sysv/linux/sh/kernel-features.h b/sysdeps/unix/sysv/linux/sh/kernel-features.h index 767df721b8..b11a5cb544 100644 --- a/sysdeps/unix/sysv/linux/sh/kernel-features.h +++ b/sysdeps/unix/sysv/linux/sh/kernel-features.h @@ -52,7 +52,9 @@ # undef __ASSUME_COPY_FILE_RANGE #endif -/* sh does not support the statx system call. */ -#undef __ASSUME_STATX +/* sh does not support the statx system call before 5.1. */ +#if __LINUX_KERNEL_VERSION < 0x050100 +# undef __ASSUME_STATX +#endif #endif
