I do not see any consistency about headers_install of <linux/kvm_para.h>
and <asm/kvm_para.h>.
According to my analysis of Linux 5.1-rc1, there are 3 groups:
[1] Both <linux/kvm_para.h> and <asm/kvm_para.h> are exported
alpha, arm, hexagon, mips, powerpc, s390, sparc, x86
[2] <asm/kvm_para.h> is exported, but <linux/kvm_para.h> is not
arc, arm64, c6x, h8300, ia64, m68k, microblaze, nios2, openrisc,
parisc, sh, unicore32, xtensa
[3] Neither <linux/kvm_para.h> nor <asm/kvm_para.h> is exported
csky, nds32, riscv
This does not match to the actual KVM support. At least, [2] is
half-baked.
Nor do arch maintainers look like they care about this. For example,
commit 0add53713b1c ("microblaze: Add missing kvm_para.h to Kbuild")
exported <asm/kvm_para.h> to user-space in order to fix an in-kernel
build error.
We have two ways to make this consistent:
[A] export both <linux/kvm_para.h> and <asm/kvm_para.h> for all
architectures, irrespective of the KVM support
[B] Match the header export of <linux/kvm_para.h> and <asm/kvm_para.h>
to the KVM support
My first attempt was [A] because the code looks cleaner, but Paolo
suggested [B].
So, this commit goes with [B].
For most architectures, <asm/kvm_para.h> was moved to the kernel-space.
I changed include/uapi/linux/Kbuild so that it checks generated
asm/kvm_para.h as well as check-in ones.
After this commit, there will be two groups:
[1] Both <linux/kvm_para.h> and <asm/kvm_para.h> are exported
arm, arm64, mips, powerpc, s390, x86
[2] Neither <linux/kvm_para.h> nor <asm/kvm_para.h> is exported
alpha, arc, c6x, csky, h8300, hexagon, ia64, m68k, microblaze,
nds32, nios2, openrisc, parisc, riscv, sh, sparc, unicore32, xtensa

Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes
the common Kbuild.asm file. Factor out the duplicated include directives
to scripts/Makefile.asm-generic so that no architecture would opt out
of the mandatory-y mechanism.
um is not forced to include mandatory-y since it is a very exceptional
case which does not support UAPI.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground into timers/2038
Pull additional syscall ABI cleanup for y2038 from Arnd Bergmann:
This is a follow-up to the y2038 syscall patches already merged in the tip
tree. As the final 32-bit RISC-V syscall ABI is still being decided on,
this is the last chance to make a few corrections to leave out interfaces
based on 32-bit time_t along with the old off_t and rlimit types.
The series achieves this in a few steps:
- A couple of bug fixes for minor regressions I introduced
in the original series
- A couple of older patches from Yury Norov that I had never
merged in the past, these fix up the openat/open_by_handle_at and
getrlimit/setrlimit syscalls to disallow the old versions of off_t
and rlimit.
- Hiding the deprecated system calls behind an #ifdef in
include/uapi/asm-generic/unistd.h
- Change arch/riscv to drop all these ABIs.
Originally, the plan was to also leave these out on C-Sky, but that now
has a glibc port that uses the older interfaces, so we need to leave
them in place.
|
|
We don't want new architectures to even provide the old 32-bit time_t
based system calls any more, or define the syscall number macros.
Add a new __ARCH_WANT_TIME32_SYSCALLS macro that gets enabled for all
existing 32-bit architectures using the generic system call table,
so we don't change any current behavior.
Since this symbol is evaluated in user space as well, we cannot use
a Kconfig CONFIG_* macro but have to define it in uapi/asm/unistd.h.
On 64-bit architectures, the same system call numbers mostly refer to
the system calls we want to keep, as they already pass 64-bit time_t.
As new architectures no longer provide these, we need new exceptions
in checksyscalls.sh.

The newer prlimit64 syscall provides all the functionality of getrlimit
and setrlimit syscalls and adds the pid of target process, so future
architectures won't need to include getrlimit and setrlimit.
Therefore drop getrlimit and setrlimit syscalls from the generic syscall
list unless __ARCH_WANT_SET_GET_RLIMIT is defined by the architecture's
unistd.h prior to including asm-generic/unistd.h, and adjust all
architectures using the generic syscall list to define it so that no
in-tree architectures are affected.

Most architectures do not export shmparam.h to user-space.
$ find arch -name shmparam.h | sort
arch/alpha/include/asm/shmparam.h
arch/arc/include/asm/shmparam.h
arch/arm64/include/asm/shmparam.h
arch/arm/include/asm/shmparam.h
arch/csky/include/asm/shmparam.h
arch/ia64/include/asm/shmparam.h

arch/nds32/include/asm/shmparam.h
arch/nios2/include/asm/shmparam.h
arch/parisc/include/asm/shmparam.h

arch/s390/include/asm/shmparam.h
arch/sh/include/asm/shmparam.h
arch/sparc/include/asm/shmparam.h
arch/x86/include/asm/shmparam.h
arch/xtensa/include/asm/shmparam.h
Strangely, some users of the asm-generic wrapper export shmparam.h
$ git grep 'generic-y += shmparam.h'
arch/c6x/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/h8300/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/hexagon/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/m68k/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/microblaze/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/openrisc/include/uapi/asm/Kbuild:generic-y += shmparam.h
arch/riscv/include/asm/Kbuild:generic-y += shmparam.h
arch/unicore32/include/uapi/asm/Kbuild:generic-y += shmparam.h
The newly added riscv correctly creates the asm-generic wrapper
in the kernel space, but the others (c6x, h8300, hexagon, m68k,
microblaze, openrisc, unicore32) create the one in the uapi directory.
Digging into the git history, now I guess fcc8487d477a ("uapi:
export all headers under uapi directories") was the misconversion.
Prior to that commit, no architecture exported to shmparam.h
As its commit description said, that commit exported shmparam.h
for c6x, h8300, hexagon, m68k, openrisc, unicore32.
83f0124ad81e ("microblaze: remove asm-generic wrapper headers")
accidentally exported shmparam.h for microblaze.
This commit unexports shmparam.h for those architectures.
There is no more reason to export include/uapi/asm-generic/shmparam.h,
so it has been moved to include/asm-generic/shmparam.h

New architectures should no longer need stat64, which is not y2038
safe and has been replaced by statx(). This removes the 'select
__ARCH_WANT_STAT64' statement from asm-generic/unistd.h and instead
moves it into the respective asm/unistd.h UAPI header files for each
architecture that uses it today.
In the generic file, the system call number and entry points are now
made conditional, so newly added architectures (e.g. riscv32 or csky)
will never need to carry backwards compatiblity for it.
arm64 is the only 64-bit architecture using the asm-generic/unistd.h
file, and it already sets __ARCH_WANT_NEW_STAT in its headers, and I
use the same #ifdef here: future 64-bit architectures therefore won't
see newstat or stat64 any more. They don't suffer from the y2038 time_t
overflow, but for consistency it seems best to also let them use statx().

Commit 0515e5999a466dfe ("bpf: introduce BPF_PROG_TYPE_PERF_EVENT
program type") introduced the bpf_perf_event_data structure which
exports the pt_regs structure. This is OK for multiple architectures
but fail for s390 and arm64 which do not export pt_regs. Programs
using them, for example, the bpf selftest fail to compile on these
architectures.
For s390, exporting the pt_regs is not an option because s390 wants
to allow changes to it. For arm64, there is a user_pt_regs structure
that covers parts of the pt_regs structure for use by user space.
To solve the broken uapi for s390 and arm64, introduce an abstract
type for pt_regs and add an asm/bpf_perf_event.h file that concretes
the type. An asm-generic header file covers the architectures that
export pt_regs today.
The arch-specific enablement for s390 and arm64 follows in separate
commits.

Many user space API headers have licensing information, which is either
incomplete, badly formatted or just a shorthand for referring to the
license under which the file is supposed to be. This makes it hard for
compliance tools to determine the correct license.
Update these files with an SPDX license identifier. The identifier was
chosen based on the license information in the file.
GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license
identifier with the added 'WITH Linux-syscall-note' exception, which is
the officially assigned exception identifier for the kernel syscall
exception:
NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
This exception makes it possible to include GPL headers into non GPL
code, without confusing license compliance tools.
Headers which have either explicit dual licensing or are just licensed
under a non GPL license are updated with the corresponding SPDX
identifier and the GPLv2 with syscall exception identifier. The format
is:
((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE)
SPDX license identifiers are a legally binding shorthand, which can be
used instead of the full boiler plate text. The update does not remove
existing license information as this has to be done on a case by case
basis and the copyright holders might have to be consulted. This will
happen in a separate step.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne. See the previous patch in this series for the
methodology of how this patch was researched.

Many user space API headers are missing licensing information, which
makes it hard for compliance tools to determine the correct license.
By default are files without license information under the default
license of the kernel, which is GPLV2. Marking them GPLV2 would exclude
them from being included in non GPLV2 code, which is obviously not
intended. The user space API headers fall under the syscall exception
which is in the kernels COPYING file:
NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
otherwise syscall usage would not be possible.
Update the files which contain no license information with an SPDX
license identifier. The chosen identifier is 'GPL-2.0 WITH
Linux-syscall-note' which is the officially assigned identifier for the
Linux syscall exception. SPDX license identifiers are a legally binding

Since commit fcc8487d477a ("uapi: export all headers under uapi
directories"), all (and only) headers under uapi directories are
exported, but asm-generic wrappers are still exceptions.
To complete de-coupling the uapi from kernel headers, move generic-y
of exported headers to uapi/asm/Kbuild.
With this change, "make headers_install" will just need to parse
uapi/asm/Kbuild to build up exported headers.
Also, move "generic-y += kprobes.h" up in order to keep the entries
sorted.

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.
In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

exported (with make headers_install_all):
