From b3c1e01a09d6af2dd7811a066ffcfc5171be2bed Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 10 Mar 2010 15:22:44 -0800 Subject: ptrace: use ptrace_request() in the remaining architectures Use ptrace_request() in the three remaining architectures that didn't use it (m68knommu, h8300, microblaze). This means: - ptrace_request now handles PTRACE_{PEEK,POKE}{TEXT,DATA} and PTRACE_DETATCH calls that were previously called directly, or in case of h8300 even open coded. - adds new support for PTRACE_SETOPTIONS/PTRACE_GETEVENTMSG/ PTRACE_GETSIGINFO/PTRACE_SETSIGINFO Signed-off-by: Christoph Hellwig Cc: Geert Uytterhoeven Cc: Yoshinori Sato Cc: Oleg Nesterov Cc: Michal Simek Acked-by: Greg Ungerer Acked-by: Roland McGrath Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/microblaze/kernel/ptrace.c | 27 +-------------------------- 1 file changed, 1 insertion(+), 26 deletions(-) (limited to 'arch/microblaze/kernel') diff --git a/arch/microblaze/kernel/ptrace.c b/arch/microblaze/kernel/ptrace.c index 4b3ac32..8c21d8b 100644 --- a/arch/microblaze/kernel/ptrace.c +++ b/arch/microblaze/kernel/ptrace.c @@ -78,26 +78,6 @@ long arch_ptrace(struct task_struct *child, long request, long addr, long data) unsigned long copied; switch (request) { - case PTRACE_PEEKTEXT: /* read word at location addr. */ - case PTRACE_PEEKDATA: - pr_debug("PEEKTEXT/PEEKDATA at %08lX\n", addr); - copied = access_process_vm(child, addr, &val, sizeof(val), 0); - rval = -EIO; - if (copied != sizeof(val)) - break; - rval = put_user(val, (unsigned long *)data); - break; - - case PTRACE_POKETEXT: /* write the word at location addr. */ - case PTRACE_POKEDATA: - pr_debug("POKETEXT/POKEDATA to %08lX\n", addr); - rval = 0; - if (access_process_vm(child, addr, &data, sizeof(data), 1) - == sizeof(data)) - break; - rval = -EIO; - break; - /* Read/write the word at location ADDR in the registers. */ case PTRACE_PEEKUSR: case PTRACE_POKEUSR: @@ -167,13 +147,8 @@ long arch_ptrace(struct task_struct *child, long request, long addr, long data) wake_up_process(child); break; - case PTRACE_DETACH: /* detach a process that was attached. */ - pr_debug("PTRACE_DETACH\n"); - rval = ptrace_detach(child, data); - break; default: - /* rval = ptrace_request(child, request, addr, data); noMMU */ - rval = -EIO; + rval = ptrace_request(child, request, addr, data); } return rval; } -- cgit v1.1
