The purpose of this patch series is:
1. We can easily add/modify/delete system call by changing entry
in syscall.tbl file. No need to manually edit many files.
2. It is easy to unify the system call implementation across all
the architectures.
The system call tables are in different format in all architecture
and it will be difficult to manually add or modify the system calls
in the respective files manually. To make it easy by keeping a script
and which'll generate the header file and syscall table file so this
change will unify them across all architectures.
syscall.tbl contains the list of available system calls along with
system call number and corresponding entry point. Add a new system
call in this architecture will be possible by adding new entry in
the syscall.tbl file.
Adding a new table entry consisting of:
- System call number.
- ABI.
- System call name.
- Entry point name.
- Compat entry name, if required.
ARM, s390 and x86 architecuture does exist the similar support. I
leverage their implementation to come up with a generic solution.
I have done the same support for work for alpha, m68k, microblaze,
mips, parisc, powerpc, sh, sparc, and xtensa. But I started sending
the patch for one architecuture for review. Below mentioned git
repository contains more details.
Git repo:- https://github.com/frzkhn/system_call_table_generator/
Finally, this is the ground work for solving the Y2038 issue. We
need to add/change two dozen of system calls to solve Y2038 issue.
So this patch series will help to easily modify from existing
system call to Y2038 compatible system calls.
I started working system call table generation on 4.17-rc1. I used
marcin's script - https://github.com/hrw/syscalls-table to generate
the syscall.tbl file. And this will be the input to the system call
table generation script. But there are couple system call got add
in the latest rc release. If run Marcin's script on latest release,
It will generate a new syscall.tbl. But I still use the old file -
syscall.tbl and once all review got over I'll update syscall.tbl
alone w.r.to the tip of the kernel. The impact of this thing, few
of the system call won't work.

All the __IGNORE* entries are resides in the uapi header
file and it is not used by any user space applications.
One of the patch in this patch series will generate the
uapi header file and system call table file. So if we move
all the __IGNORE* entries to non uapi header, it will simplify
the uapi header and system call table file generation script.
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.

NR_syscalls macro holds the number of system call exist in SPARC
architecture. This macro is currently the part of uapi/asm/unistd.h
file. 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 number of system call information. So we have two option to update
NR_syscalls value.
1. Update NR_syscalls in uapi/asm/unistd.h manually by counting the
no.of system calls. No need to update NR_syscalls until we either
add a new system call or delete an existing system call.
2. We can keep this feature it above mentioned script, that'll
count the number of syscalls and keep it in a generated file.
In this case we don't need to explicitly update NR_syscalls
in asm/unistd.h file.
The 2nd option will be the recommended one. For that, I moved the
NR_syscalls macro from uapi/asm/unistd.h to asm/unistd.h. The macro
name also changed form NR_syscalls to __NR_syscalls 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.

The system call tables are in different format in all
architecture and it will be difficult to manually add or
modify the system calls in the respective files. To make
it easy by keeping a script and which'll generate the
header file and syscall table file so this change will
unify them across all architectures.
The system call table generation script is added in
syscalls directory which contain the script to generate
both uapi header file system call table generation file
and syscall_32/64.tbl file which'll be the input for the
scripts.
syscall_32/64.tbl contains the list of available system calls
along with system call number and corresponding entry point.
Add a new system call in this architecture will be possible
by adding new entry in the syscall_32/64.tbl file.
Adding a new table entry consisting of:
- System call number.
- ABI.
- System call name.
- Entry point name.
- Compat entry name, if required.
syscallhdr.sh and syscalltbl.sh will generate uapi header-
unistd_32/64.h and syscall_table_32/64/c32.h files respectively.
File syscall_table_32/64/c32.h is included by syscall.S - the
real system call table. Both .sh files will parse the content
syscall.tbl to generate the header and table files.
ARM, s390 and x86 architecuture does have the similar support.
I leverage their implementation to come up with a generic
solution.

System call table generation script must be run to generate
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 arch/sparc/Makefile and the generated files against
the removed files will be identical.
The generated uapi header file will be included in uapi/asm/
unistd_32/64.h and generated system call table support file will
be included by arch/sparc/kernel/syscall_table_32/64.S file.

This is certainly required in the uapi header as of this patch,
without it all the numbers are wrong when you include the
file from user space.
I suppose it can be removed later once the header is replaced
with the two generated versions,
> -/* Bitmask values returned from kern_features system call. */
> -#define KERN_FEATURE_MIXED_MODE_STACK 0x00000001
I'm fairly sure this also needs to remain in the uapi/asm/unistd.h header
as a start, so that user space can call the sys_kern_features() system
call and interpret its result when only the first patch is applied.

This part is fine.

What about the suggestion that was made earlier to enclose this in
#ifdef __KERNEL__?

I would argue that for sparc we only want a single input
table, since the 32/64 versions are similar enough that the
differences can be addressed with 'abi' flag, rather than
having everything marked as 'common'. Isn't that the
purpose of the abi flag in the first place?

The issue, keeping __NR_syscalls in uapi header was pointed out by
Michal Simek (microblaze) and Geert Uytterhoeven (m68k). I replied
them with this suggestion (enclose with #ifdef __KERNEL__). Once
they agree, my next version of patch series will have this change.

Yes, we can do that way also. But few concerns I would
like to share with you.
I feel it add the complexity in the scripts. eg:-
108 32 setresuid32 sys_setresuid
108 64 setresuid sys_setresuid
This case the script has to be smart enough to parse the
.tbl file properly. It need more logic in the scripts. This is
not common. So if you keep separate .tbl we can avoid
this.
ABI flag is serving *nothing* in all other architecture including
SPARC.
But as I told in the cover letter, I followed x86/arm/
s390 architecture's system table generation implementation.
They are keeping ABI flag. In our case we can delete this
flag completely from all architectures.
Most of the architecture these 32/64 similarity is absent.
So it would be better keep separate files to maintain a
generic script across all architecture.
One question here is; while invoking the script I'm passing
the abi flag. It is simply keeping in the .tbl file to make the
file similar to x86. What I can do here?

The script will generate 2 versions, ie, unistd_32.h and unistd_64.h.
Please give few more pointer here.

Sure. I'll update in the next patch series. Thanks!

You still need to check at least for __arch64__ in asm/unistd.h in order
to pick which header to include, right? Since the
__32bit_syscall_numbers__ check was already in the public header
file, it may also be possible that there is some user space application
that sets this in order to get the 32-bit definitions. This might e.g.
be needed for strace.
