LinuxLists.cc - [PATCH 0/3] System call table generation support

Subject: [PATCH 0/3] System call table generation support

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,
ia64, powerpc, parisc, 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.

Subject: [PATCH 1/3] mips: Add __NR_syscalls macro in uapi/asm/unistd.h

NR_syscalls macro holds the number of system call exist in MIPS
architecture. This macro is currently not a part of uapi/asm/unistd.h
file. The purpose of this macro is 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. 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 architecture and modify the system it easy by keeping header file and unify them across
The system call syscalls directory both uapi header and syscall_32/64.tbl scripts.

syscall_32/64/n32.tbl calls along with point. Add a new possible by adding file.

Adding a new table - System call number.
- ABI.
- System call name.
- Entry point name.
- Compat
syscallhdr.sh and unistd_32/64.h and File syscall_table_*.h real system call syscall.tbl to generate
ARM, s390 and x86 I leverage their solution.

Subject: [PATCH 3/3] mips: uapi header and system call table file generation

System call table generation script must be run to generate
unistd_*.h and syscall_table_*.h files. This patch will have
changes which will invokes the script.

This patch will generate unistd_*.h and syscall_table_*.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_*.h and generated system call table support file will
be included by arch/mips/kernel/syscall_table_*.S file.

I think it would be best to name the files
o32/n64/n32 instead of 32/64/n32

It would also be helpful to mention why the n32/n64
files cannot be combined into one nfile here.

You missed the additon of rseq and io_pgetevetns here.

Interesting :)

I actually started on something similar recently with the goals of
reducing the need to adjust both asm/unistd.h & the syscall entry tables
when adding syscalls, clean up asm/unistd.h a bit & make it
easier/cleaner to add support for nanoMIPS & the P32 ABI.

My branch still needed some work but it's here if you're interested:

git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux.git wip-mips-syscalls

https://git.kernel.org/pub/scm/linux/kernel/git/mips/linux.git/log/?h=wip-mips-syscalls

There are some differences:

- I'd placed syscall numbers the 3 current MIPS ABIs in one table,
rather than splitting it up. I can see pros & cons to both though so
I'm not tied to having a single all-encompassing table.

- I'd mostly inferred the entry point names from the syscall names,
only specifying them where they differ. Again I'm not particularly
tied to this.

- I'd made asm/unistd.h behave like asm-generic/unistd.h with the
__SYSCALL() macro, where you generate separate syscall_table_*
headers. I'm fine with that too.

So I'm pretty happy to go with your series, though I agree with Arnd on
the ABI/file naming & the missing syscalls that were added in the 4.18
cycle. We probably need to provide mipsmt_sys_sched_[gs]etaffinity as
aliases to sys_sched_[gs]etaffinity when CONFIG_MIPS_MT_FPAFF isn't
enabled in order to fix the issue the kbuild test robot reported.

But I'm looking forward to v2 :)

Thanks,
Paul

As I mentioned in the cover letter:
"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."

Hopefully, the next version does have this change. Thanks!

Thanks for your comments :)

We're planning to come up with a generic script for system call table
generation across all the architecture. So certain things I have to keep
same across all the architecture.

Having a single script is always our plan for long run. But I have to keep a
separate versions for the start so each architecture can be handled in one
series. Which would make easier to merge in the initial version.

we could probably add it to scripts/*.sh first, but that requires more
coordination between the architectures.

This looks like a very nice approach that we would probably prefer if we wanted
to do it only for mips. The way Firoz did it makes sense in the context of doing
it the same way on all architectures, where usually the information is more
accessible to human readers by using the number as the primary key.

Speaking of nanoMIPS, what is your plan for the syscall ABI there?
I can see two ways of approaching it:

a) keep all the MIPSisms in the data structures, and just use a subset of
o32 that drops all the obsolete entry points
b) start over and stay as close as possible to the generic ABI, using the
asm-generic versions of both the syscall table and the uapi header
files instead of the traditional version.

Yup, I completely agree that moving all this towards being common
infrastructure for all architectures is a worthy goal :)

We've taken option b in our current downstream kernel & that's what I
hope we'll get upstream too. There's no expectation that we'll ever need
to mix pre-nanoMIPS & nanoMIPS ISAs or their associated ABIs across the
kernel/user boundary so it's felt like a great opportunity to clean up &
standardise.

Getting nanoMIPS/p32 support submitted upstream is on my to-do list, but
there's a bunch of prep work to get in first & of course that to-do list
is forever growing. Hopefully in the next couple of cycles.

Thanks,
Paul

p32 is just the ABI name for nanoMIPS or yet another MIPS ABI?

Either way, І think if there is yet another ABI even on an existing port
we should always aim for the asm-generic syscall table indeed.

Especially for mips where o32 has a rather awkward ABI only explained by
odd decisions more than 20 years ago.

p32 is the ABI for nanoMIPS - ie. it is a new ABI, but it's not for use
with pre-nanoMIPS ISAs & nanoMIPS isn't used with o32/n32/n64.

Some of the code density improvements nanoMIPS brings are due to the ISA
& p32 ABI being developed together - eg. the load/store multiple &
save/restore instructions make it easy to save sequences of $sp, $fp,
$ra & some number of the $sN callee-saved registers. Compressed register
number encodings generally include registers that make sense for the p32
ABI, and I'm sure there were other things I've forgotten.

Glad to hear we're on the same page :)

I'm all for being less "special" & couldn't care less if our nanoMIPS
support isn't compatible with IRIX.
