From 56b98bf1fb819b357318f39fccf2901d3c6b41ec Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 11 Dec 2018 16:57:49 -0200 Subject: alpha: Use Linux generic sigaction implementation Alpha rt_sigaction syscall uses a slight different kernel ABI than generic one: arch/alpha/kernel/signal.c 90 SYSCALL_DEFINE5(rt_sigaction, int, sig, const struct sigaction __user *, act, 91 struct sigaction __user *, oact, 92 size_t, sigsetsize, void __user *, restorer) Similar as sparc, the syscall expects a restorer function. However different than sparc, alpha defines the restorer as the 5th argument (sparc defines as the 4th). This patch removes the arch-specific alpha sigaction implementation, adapt the Linux generic one to different restore placements (through STUB macro), and make alpha use the Linux generic kernel_sigaction definition. Checked on alpha-linux-gnu and x86_64-linux-gnu (for sanity). * sysdeps/unix/sysv/linux/alpha/Makefile: Update comment about __syscall_rt_sigaction. * sysdeps/unix/sysv/linux/alpha/kernel_sigaction.h (kernel_sigaction): Use Linux generic defintion. (STUB): Define. (__syscall_rt_sigreturn, __syscall_sigreturn): Add prototype. * sysdeps/unix/sysv/linux/alpha/rt_sigaction.S (__syscall_rt_sigaction): Remove implementation. (__syscall_sigreturn, __syscall_rt_sigreturn): Define as global and hidden. * sysdeps/unix/sysv/linux/alpha/sigaction.c: Remove file. * sysdeps/unix/sysv/linux/alpha/sysdep.h (INLINE_SYSCALL, INTERNAL_SYSCALL): Remove definitions. * sysdeps/unix/sysv/linux/sigaction.c: Define STUB to accept both the action and signal set size. * sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c (STUB): Redefine. * sysdeps/unix/sysv/linux/sparc/sparc64/sigaction.c (STUB): Likewise. --- ChangeLog | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index 7891b7a..f304e58 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,4 +1,24 @@ 2018-12-18 Adhemerval Zanella + + * sysdeps/unix/sysv/linux/alpha/Makefile: Update comment about + __syscall_rt_sigaction. + * sysdeps/unix/sysv/linux/alpha/kernel_sigaction.h + (kernel_sigaction): Use Linux generic defintion. + (STUB): Define. + (__syscall_rt_sigreturn, __syscall_sigreturn): Add prototype. + * sysdeps/unix/sysv/linux/alpha/rt_sigaction.S + (__syscall_rt_sigaction): Remove implementation. + (__syscall_sigreturn, __syscall_rt_sigreturn): Define as global and + hidden. + * sysdeps/unix/sysv/linux/alpha/sigaction.c: Remove file. + * sysdeps/unix/sysv/linux/alpha/sysdep.h (INLINE_SYSCALL, + INTERNAL_SYSCALL): Remove definitions. + * sysdeps/unix/sysv/linux/sigaction.c: Define STUB to accept both the + action and signal set size. + * sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c (STUB): Redefine. + * sysdeps/unix/sysv/linux/sparc/sparc64/sigaction.c (STUB): Likewise. + +2018-12-18 Adhemerval Zanella James Clarke [BZ #23960] -- cgit v1.1
