From 87686aeefdf419bc7d02cae25f5b45e9306ba6ff Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 26 Aug 2016 10:42:58 -0300 Subject: Consolidate Linux ftruncate implementations THis patch consolidates all Linux ftruncate implementation on sysdeps/unix/sysv/linux/ftruncate{64}.c. It is based on {INTERNAL,INLINE}_SYSCALL patch [1] to simplify the syscall construction. General idea is to build ftruncate iff __OFF_T_MATCHES_OFF64_T is not defined, otherwise ftruncate64 will be build and ftruncate will be an alias. The fallocate will use old compat syscall and pass 32-bit off_t argument, while fallocate64 will handle the correct off64_t passing using __ALIGNMENT_ARG and SYSCALL_LL64 macros. Tested on x86_64, i386, aarch64, and armhf. * posix/tst-truncate-common.c: New file. * posix/tst-truncate.c: Use tst-truncate-common.c. * posix/tst-truncate64.c: Likewise and add LFS tests. * sysdeps/unix/sysv/linux/arm/ftruncate64.c: Remove file. * sysdeps/unix/sysv/linux/generic/wordsize-32/ftruncate.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/ftruncate64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/ftruncate64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/ftruncate64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/ftruncate64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/ftruncate64.c: Likewise. * sysdeps/unix/sysv/linux/ftruncate.c: New file. * sysdeps/unix/sysv/linux/ftruncate64.c (__ftruncate64): Use INLINE_SYSCALL_CALL, __ALIGNMENT_ARG and SYSCALL_LL64 macros. [__OFF_T_MATCHES_OFF64_T] (ftruncate): Add alias. * sysdeps/unix/sysv/linux/mips/mips64/syscalls.list (ftruncate): Remove. * sysdeps/unix/sysv/linux/wordsize-64/syscalls.list (ftruncate): Likewise.
