People usually add backward-compatible shims for libc to use older interfaces on old kernels. There is no reason to keep the compat shims after many years of the transition. Patch below purges the compat code for pre-r171219, which added pad-less versions of syscalls taking off_t, and for r177911, which handles the struct flock/oflock transition. This is 6.x/7.x compat, we absolutely not support running HEAD libc on such old kernels. diff --git a/lib/libc/amd64/sys/Makefile.inc b/lib/libc/amd64/sys/Makefile.inc index 8e0d614..46ea955 100644 --- a/lib/libc/amd64/sys/Makefile.inc +++ b/lib/libc/amd64/sys/Makefile.inc @@ -11,6 +11,3 @@ MDASM= vfork.S brk.S cerror.S exect.S getcontext.S pipe.S ptrace.S \ NOASM= break.o exit.o getlogin.o openbsd_poll.o sstk.o vfork.o yield.o PSEUDO= _getlogin.o _exit.o -.if ${MK_SYSCALL_COMPAT} != "no" -PSEUDO+= _pread.o _pwrite.o _lseek.o _mmap.o _ftruncate.o _truncate.o -.endif diff --git a/lib/libc/arm/sys/Makefile.inc b/lib/libc/arm/sys/Makefile.inc index f36ab71..60c2dc3 100644 --- a/lib/libc/arm/sys/Makefile.inc +++ b/lib/libc/arm/sys/Makefile.inc @@ -8,6 +8,3 @@ MDASM= Ovfork.S brk.S cerror.S pipe.S ptrace.S sbrk.S shmat.S sigreturn.S syscal NOASM= break.o exit.o getlogin.o openbsd_poll.o sstk.o vfork.o yield.o PSEUDO= _exit.o _getlogin.o -.if ${MK_SYSCALL_COMPAT} != "no" -PSEUDO+= _pread.o _pwrite.o _lseek.o _mmap.o _ftruncate.o _truncate.o -.endif diff --git a/lib/libc/i386/sys/Makefile.inc b/lib/libc/i386/sys/Makefile.inc index b56183c..ebaa462 100644 --- a/lib/libc/i386/sys/Makefile.inc +++ b/lib/libc/i386/sys/Makefile.inc @@ -15,9 +15,6 @@ MDASM= Ovfork.S brk.S cerror.S exect.S getcontext.S pipe.S ptrace.S \ NOASM= break.o exit.o getlogin.o openbsd_poll.o sstk.o vfork.o yield.o PSEUDO= _getlogin.o _exit.o -.if ${MK_SYSCALL_COMPAT} != "no" -PSEUDO+= _pread.o _pwrite.o _lseek.o _mmap.o _ftruncate.o _truncate.o -.endif MAN+= i386_get_ioperm.2 i386_get_ldt.2 i386_vm86.2 MAN+= i386_set_watch.3 diff --git a/lib/libc/include/compat.h b/lib/libc/include/compat.h index 2b8f0de..6ab17d7 100644 --- a/lib/libc/include/compat.h +++ b/lib/libc/include/compat.h @@ -47,9 +47,7 @@ __sym_compat(shmctl, freebsd7_shmctl, FBSD_1.0); #define __weak_reference(sym,alias) \ .weak alias;.equ alias,sym -#ifndef SYSCALL_COMPAT __weak_reference(__sys_fcntl,__fcntl_compat) -#endif #undef __weak_reference diff --git a/lib/libc/include/libc_private.h b/lib/libc/include/libc_private.h index ceaa2a3..53be867 100644 --- a/lib/libc/include/libc_private.h +++ b/lib/libc/include/libc_private.h @@ -276,21 +276,12 @@ extern void (*__cleanup)(void) __hidden; /* * Get kern.osreldate to detect ABI revisions.
