From 0bb2fabcb3bcac064a3d89917c0736353cdac2f4 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 3 Jul 2017 15:00:26 -0300 Subject: Consolidate non cancellable openat call This patch consolidates all the non cancellable openat{64} calls to use the __openat{64}_nocancel identifier. For non cancellable targets it will be just a macro to call the default respective symbol while on Linux will be a internal one. Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu. * sysdeps/generic/not-cancel.h (openat_not_cancel): Remove macro. (openat_not_cancel_3): Likewise. (openat64_not_cancel_3): Likewise). (openat_not_cancel_3): Likewise). * sysdeps/unix/sysv/linux/not-cancel.h (openat_not_cancel): Remove macro. (openat_not_cancel_3): Likewise. (openat64_not_cancel): Likewise. (openat64_not_cancel_3): Likewise. * sysdeps/unix/sysv/linux/openat.c (__openat_nocancel): New function. * sysdeps/unix/sysv/linux/openat64.c (__openat64_nocancel): Likewise. * io/ftw.c (open_dir_stream): Replace openat{64}_not_cancel{_3} with __open{64}_nocancel. * sysdeps/mach/hurd/opendir.c (__opendirat): Likewise. * sysdeps/posix/getcwd.c (__getcwd): Likewise. * sysdeps/posix/opendir.c (__opendirat): Likewise. --- sysdeps/unix/sysv/linux/not-cancel.h | 18 ++++++++---------- 1 file changed, 8 insertions(+), 10 deletions(-) (limited to 'sysdeps/unix/sysv/linux/not-cancel.h') diff --git a/sysdeps/unix/sysv/linux/not-cancel.h b/sysdeps/unix/sysv/linux/not-cancel.h index 84dc72a..08ad773 100644 --- a/sysdeps/unix/sysv/linux/not-cancel.h +++ b/sysdeps/unix/sysv/linux/not-cancel.h @@ -34,6 +34,14 @@ libc_hidden_proto (__open_nocancel) __typeof (open64) __open64_nocancel; libc_hidden_proto (__open64_nocancel) +/* Non cancellable openat syscall. */ +__typeof (openat) __openat_nocancel; +libc_hidden_proto (__openat_nocancel) + +/* Non cacellable openat syscall (LFS version). */ +__typeof (openat64) __openat64_nocancel; +libc_hidden_proto (__openat64_nocancel) + /* Non cancellable read syscall. */ __typeof (__read) __read_nocancel; libc_hidden_proto (__read_nocancel) @@ -42,16 +50,6 @@ libc_hidden_proto (__read_nocancel) __typeof (__write) __write_nocancel; libc_hidden_proto (__write_nocancel) -/* Uncancelable openat. */ -#define openat_not_cancel(fd, fname, oflag, mode) \ - INLINE_SYSCALL (openat, 4, fd, fname, oflag, mode) -#define openat_not_cancel_3(fd, fname, oflag) \ - INLINE_SYSCALL (openat, 3, fd, fname, oflag) -#define openat64_not_cancel(fd, fname, oflag, mode) \ - INLINE_SYSCALL (openat, 4, fd, fname, oflag | O_LARGEFILE, mode) -#define openat64_not_cancel_3(fd, fname, oflag) \ - INLINE_SYSCALL (openat, 3, fd, fname, oflag | O_LARGEFILE) - /* Uncancelable close. */ #define __close_nocancel(fd) \ INLINE_SYSCALL (close, 1, fd) -- cgit v1.1
