sparc: generate uapi header and system call table files

2018-11-19T02:52:22Z

System call table generation script must be run to gener- ate unistd_32/64.h and syscall_table_32/64/c32.h files. This patch will have changes which will invokes the script. This patch will generate unistd_32/64.h and syscall_table- _32/64/c32.h files by the syscall table generation script invoked by parisc/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/systbls_32/64.S file.

sparc: add __NR_syscalls along with NR_syscalls

2018-11-19T02:52:22Z

NR_syscalls macro holds the number of system call exist in sparc architecture. We have to change the value of NR- _syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update NR_sy- scalls value. 1. Update NR_syscalls in asm/unistd.h manually by count- ing the no.of system calls. No need to update NR_sys- calls until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update NR_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with NR_syscalls asm/unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects. Signed-off-by: Firoz Khan Signed-off-by: David S. Miller

sparc: move __IGNORE* entries to non uapi header

2018-11-19T02:52:21Z

All the __IGNORE* entries are resides in the uapi header file move to non uapi header asm/unistd.h as it is not used by any user space applications. It is correct to keep __IGNORE* entry in non uapi header asm/unistd.h while uapi/asm/unistd.h must hold information only useful for user space applications. One of the patch in this patch series will generate uapi header file. The information which directly used by the user space application must be present in uapi file.

License cleanup: add SPDX license identifier to uapi header files with no license

2017-11-02T10:19:54Z

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 shorthand, which can be used instead of the full boiler plate text. 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.

The GLIBC folks would like to eliminate socketcall support eventually, and this makes sense regardless so wire them all up. Signed-off-by: David S. Miller
