Subject: [PATCH 0/2] uprobes: Change handle_swbp() to expose bp_vaddr to handler_chain()
Date: Sun, 30 Dec 2012 16:46:57 +0100 [thread overview]
Message-ID: <20121230154657.GA28488@redhat.com> (raw)
Hello.
Inspired by the recent uretrpobe RFC's. I think it simply makes no sense
to call handler/skip/arch_uprobe_pre_xol with regs->ip pointing to the
"random" address after the task hits bp.
Ananth, could you please confirm 2/2 can't break powerpc? It "obviously"
shouldn't because uprobe_get_swbp_addr() is a "nop" on ppc, but still
your ack is welcomed.
Oleg.
