From e16b27816462de700f9508d86954410c41105dc2 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sun, 20 Apr 2008 13:10:12 -0700 Subject: [PATCH] ptrace: compat_ptrace_request siginfo This adds support for PTRACE_GETSIGINFO and PTRACE_SETSIGINFO in compat_ptrace_request. It relies on existing arch definitions for copy_siginfo_to_user32 and copy_siginfo_from_user32. On powerpc, this fixes a longstanding regression of 32-bit ptrace calls on 64-bit kernels vs native calls (64-bit calls or 32-bit kernels). This can be seen in a 32-bit call using PTRACE_GETSIGINFO to examine e.g. siginfo_t.si_addr from a signal that sets it. (This was broken as of 2.6.24 and, I presume, many or all prior versions.)
