y2038: sh: remove timeval/timespec usage from headers

2019-12-18T17:07:33+00:00

This header file escaped my earlier cleanups for removing the in-kernel usage of timeval and timespec structs. Replace them with the corresponding __kernel_old_* types. Acked-by: Rich Felker Signed-off-by: Arnd Bergmann

treewide: add "WITH Linux-syscall-note" to SPDX tag of uapi headers

2019-07-25T09:05:10+00:00

UAPI headers licensed under GPL are supposed to have exception "WITH Linux-syscall-note" so that they can be included into non-GPL user space application code. The exception note is missing in some UAPI headers. Some of them slipped in by the treewide conversion commit b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license"). Just run: $ git show --oneline b24413180f56 -- arch/x86/include/uapi/asm/ I believe they are not intentional, and should be fixed too. This patch was generated by the following script: git grep -l --not -e Linux-syscall-note --and -e SPDX-License-Identifier \ -- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild | while read file do sed -i -e '/[[:space:]]OR[[:space:]]/s/$GPL-[^[:space:]]*$/(\1 WITH Linux-syscall-note)/g' \ -e '/[[:space:]]or[[:space:]]/s/$GPL-[^[:space:]]*$/(\1 WITH Linux-syscall-note)/g' \ -e '/[[:space:]]OR[[:space:]]/!{/[[:space:]]or[[:space:]]/!s/$GPL-[^[:space:]]*$/\1 WITH Linux-syscall-note/g}' $file done After this patch is applied, there are 5 UAPI headers that do not contain "WITH Linux-syscall-note". They are kept untouched since this exception applies only to GPL variants. $ git grep --not -e Linux-syscall-note --and -e SPDX-License-Identifier \ -- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild include/uapi/drm/panfrost_drm.h:/* SPDX-License-Identifier: MIT */ include/uapi/linux/batman_adv.h:/* SPDX-License-Identifier: MIT */ include/uapi/linux/qemu_fw_cfg.h:/* SPDX-License-Identifier: BSD-3-Clause */ include/uapi/linux/vbox_err.h:/* SPDX-License-Identifier: MIT */ include/uapi/linux/virtio_iommu.h:/* SPDX-License-Identifier: BSD-3-Clause */ Signed-off-by: Masahiro Yamada Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

net: socket: implement 64-bit timestamps

2019-04-19T21:07:40+00:00

The 'timeval' and 'timespec' data structures used for socket timestamps are going to be redefined in user space based on 64-bit time_t in future versions of the C library to deal with the y2038 overflow problem, which breaks the ABI definition. Unlike many modern ioctl commands, SIOCGSTAMP and SIOCGSTAMPNS do not use the _IOR() macro to encode the size of the transferred data, so it remains ambiguous whether the application uses the old or new layout. The best workaround I could find is rather ugly: we redefine the command code based on the size of the respective data structure with a ternary operator. This lets it get evaluated as late as possible, hopefully after that structure is visible to the caller. We cannot use an #ifdef here, because inux/sockios.h might have been included before any libc header that could determine the size of time_t. The ioctl implementation now interprets the new command codes as always referring to the 64-bit structure on all architectures, while the old architecture specific command code still refers to the old architecture specific layout. The new command number is only used when they are actually different. Signed-off-by: Arnd Bergmann Signed-off-by: David S. Miller

KVM: export and iif KVM is supported

2019-03-28T16:27:42+00:00

I do not see any consistency about headers_install of and . According to my analysis of Linux 5.1-rc1, there are 3 groups: [1] Both and are exported alpha, arm, hexagon, mips, powerpc, s390, sparc, x86 [2] is exported, but is not arc, arm64, c6x, h8300, ia64, m68k, microblaze, nios2, openrisc, parisc, sh, unicore32, xtensa [3] Neither nor 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 to user-space in order to fix an in-kernel build error. We have two ways to make this consistent: [A] export both and for all architectures, irrespective of the KVM support [B] Match the header export of and 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, 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 and are exported arm, arm64, mips, powerpc, s390, x86 [2] Neither nor is exported alpha, arc, c6x, csky, h8300, hexagon, ia64, m68k, microblaze, nds32, nios2, openrisc, parisc, riscv, sh, sparc, unicore32, xtensa Signed-off-by: Masahiro Yamada Acked-by: Cornelia Huck Signed-off-by: Paolo Bonzini

kbuild: force all architectures except um to include mandatory-y

2019-03-17T03:56:32+00:00

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.

sh: remove duplicate unistd_32.h file

2019-01-25T16:22:50+00:00

When I merged this patch, the file was accidentally left intact instead of being removed, which means any changes to syscall.tbl have no effect. Fixes: 2b3c5a99d5f3 ("sh: generate uapi header and syscall table header files") Signed-off-by: Arnd Bergmann

arch: remove redundant UAPI generic-y defines

2019-01-06T01:22:15+00:00

Now that Kbuild automatically creates asm-generic wrappers for missing mandatory headers, it is redundant to list the same headers in generic-y and mandatory-y. Suggested-by: Sam Ravnborg Signed-off-by: Masahiro Yamada Acked-by: Sam Ravnborg

arch: remove stale comments "UAPI Header export list"

2019-01-06T00:46:51+00:00

These comments are leftovers of commit fcc8487d477a ("uapi: export all headers under uapi directories"). Prior to that commit, exported headers must be explicitly added to header-y. Now, all headers under the uapi/ directories are exported. Signed-off-by: Masahiro Yamada

sh: generate uapi header and syscall table header files

2018-12-19T16:54:40+00:00

System call table generation script must be run to gener- ate unistd_32.h and syscall_table.h files. This patch will have changes which will invokes the script. This patch will generate unistd_32.h and syscall_table.h files by the syscall table generation script invoked by sh/Makefile and the generated files against the removed files must be identical. The generated uapi header file will be included in uapi/- asm/unistd.h and generated system call table header file will be included by kernel/syscall_32.S file.
