Commit Message

Adhemerval Zanella May 21, 2015, 7:56 p.m.
This patch removes the socket.S implementation for all ports and replace
it by a C implementation using socketcall.  For ports that implement
the syscall directly, there is no change.

The patch idea is to simplify the socket function implementation that
uses the socketcall to be based on C implemetation instead of a pseudo
assembly implementation with arch specific parts.  The patch then remove
the assembly implementatation for the ports which uses socketcall
(i386, microblaze, mips, powerpc, sparc, m68k, s390 and sh).

I have cross-build GLIBC for afore-mentioned ports and tested on both
i386 and ppc32 without regressions.

Changes from previous version:

- Removed ARM internal_{accept4,recvmmsg,sendmmsg}.S
- Fixed mips32 ChangeLog entry
- Removed m68k socket.S (no build issues)
- Added auxiliary macros for SOCKETCALL and SOCKETCALL_CANCEL so
  only the required number of arguments for socketcall is allocated
  in the stack.

Indeed there is zero-arg socket call, so I will just remove it.

I doubt that this can compile. :-/

I propose to radically simplify this logic and simply require at least 
kernel version 3.2.18 on ia64, so that we always have either an accept4 
system call or an accept4 socket call.  I have something approaching a 
patch for that.

(accept4 support was backported to the 3.2 stable series on ia64 because 
it was realized that too much broke on ia64 due to the missing support.)

Thanks,
Florian

In fact it compiles fine because we do have SOCKOP_invalid defined:

sysdeps/unix/sysv/linux/socketcall.h:28:#define SOCKOP_invalid          -1

I agree this seems the best approach and I will review your accept4 patch.

-/* The socket-oriented system calls are handled unusually in Linux.
-   They are all gated through the single `socketcall' system call number.
-   `socketcall' takes two arguments: the first is the subcode, specifying
-   which socket function is being called; and the second is a pointer to
-   the arguments to the specific function.
-
-   The .S files for the other calls just #define socket and #include this.  */
