[PATCH net-next] tools headers: Sync uapi/asm-generic/socket.h with the kernel sources

[Alexander Mikhalitsyn]

This also fixes a wrong definitions for SCM_TS_OPT_ID & SO_RCVPRIORITY.

Accidentally found while working on another patchset.

I'm not sure if it's a bug. As you may notice, in
arch/parisc/include/uapi/asm/socket.h, it has its own management of
definitions.

I'm worried that since this file is uapi, is it allowed to adjust the
number like this patch does if it's not a bug.

Otherwise, the change looks good to me.

Thanks,
Jason

Hi Jason,

Thanks for looking into this!

My understanding is that this file (tools/include/uapi/asm-generic/socket.h) is
a mirror copy of the actual UAPI file (uapi/asm-generic/socket.h),
and definitions need to be in sync with it.

But I absolutely agree that we need someone who knows that for sure
and can confirm.
Breaking anything, especially UAPI-related stuff is my nightmare.

I don’t completely understand this either—if the definitions need to
be in sync, why is there a discrepancy?

Specifically, I am referring to the ones that caused the shift in
numbering in uapi/asm-generic/socket.h:
#define SO_DEVMEM_LINEAR 78
#define SCM_DEVMEM_LINEAR SO_DEVMEM_LINEAR
#define SO_DEVMEM_DMABUF 79
#define SCM_DEVMEM_DMABUF SO_DEVMEM_DMABUF
#define SO_DEVMEM_DONTNEED 80

In the case of SO_RCVPRIORITY, I simply continued the numbering
sequence as it was—I didn’t intend to disrupt the structure of the
definitions. It’s possible that I made a mistake in doing so.
If this doesn’t cause any issues, I would also vote for modifying the
numbering. Could someone more familiar with this area confirm whether
adjusting the numbering is acceptable?

The uAPI number definions are different between arch, but strictly,
files under tools/ are not the source of truth.

This should've followed include/uapi/asm-generic/socket.h.

Otherwise, a program compiled with tools/include/uapi/asm-generic/socket.h
does not work on kernel compiled with include/uapi/asm-generic/socket.h,
and the prog will invoke syscall with an unintentional number.

So, tools/include/uapi must be synced with include/uapi and fixing
up wrong definitions under tools/include/uapi is totally fine, and
this does not cause uAPI breakage, rather it's been broken.

It seems the patch is marked as Changes Requested on patchwork.
Also, I think this is net.git material than net-next.

So, could you repost to net.git ?

Thanks!
