io: Consolidate lockf implementation
With internal fcntl64 internal (commit 06ab719d), it is possible to consolidate lockf implementation by using the LFS fcntl interface instead of using arch and system-specific implementations. For Linux, the i386 implementation is used as generic implementation by replacing the direct syscall with fcntl64 call. The LFS symbol alias for default LFS ABI (__OFF_T_MATCHES_OFF64_T) is used to avoid the duplicate symbol (instead of overriding the implementation with an empty file). For Hurd lockf64 semantic is changed: previous generic lockf64 implementation returned EOVERFLOW if LEN input is larger than 32-bit off_t. However, Hurd fcntl64 implementation for F_GETLK64, F_SETLK64, and F_SETLKW64 do accept off64_t inputs (__f_setlk accepts only off64_t inputs). Checked on i686-linux-gnu and x86_64-linux-gnu along with a i686-gnu build. * io/Makefile (tests): Add tst-lockf. * io/lockf.c (lockf): Use __fcntl and only define for !__OFF_T_MATCHES_OFF64_T. * io/lockf64.c (__lockf64): Call __fcntl64 and alias to lockf for __OFF_T_MATCHES_OFF64_T case. * io/tst-lockf.c: New file. * sysdeps/unix/sysv/linux/i386/lockf64.c: Remove file. * sysdeps/unix/sysv/linux/arm/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/m68k/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/sh/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/lockf64.c: Likewise.
