A natural fix would be to make xxx_get_debug_reg_state take an inferior argument, but that doesn't work because of the case where we detach breakpoints/watchpoints from the child fork, at a time there's no inferior for the child fork at all. We do a nasty hack in i386_inferior_data_get, but that relies on all callers pointing the current inferior to the correct inferior, which isn't actually being done by all callers, and I don't think we want to enforce that -- deep in the bowls of linux-nat.c, there are many cases we resume lwps behind the scenes, and it's be better to not have that code rely on global state (as it doesn't today). The fix is to decouple the watchpoints code from inferiors, making it track target processes instead. This way, we can freely keep track of the watchpoint mirrors for these processes behind the core's back. Checkpoints also play dirty tricks with swapping the process behind the inferior, so they get special treatment too in the patch (which just amounts to calling a new hook). Instead of the old hack in i386_inferior_data_get, where we returned a copy of the current inferior's debug registers mirror, as soon as we detect a fork in the target, we copy the debug register mirror from the parent to the child process. I don't have an old kernel handy to test, but I stepped through gdb doing the watchpoint removal in the fork child in the watchpoint-fork test seeing that the debug registers end up cleared in the child. I didn't find the need for linux_nat_iterate_watchpoint_lwps. If we use plain iterate_over_lwps instead, what happens is that when removing watchpoints, that iterate_over_lwps doesn't actually iterate over anything, since the fork child is not added to the lwp list until later, at detach time, in linux_child_follow_fork. And if we don't iterate over that lwp, we don't mark its debug registers as needing update. But linux_child_follow_fork takes care of doing that explicitly: child_lp = add_lwp (inferior_ptid); child_lp->stopped = 1; child_lp->last_resume_kind = resume_stop; make_cleanup (delete_lwp_cleanup, child_lp); /* CHILD_LP has new PID, therefore linux_nat_new_thread is not called for it. See i386_inferior_data_get for the Linux kernel specifics. Ensure linux_nat_prepare_to_resume will reset the hardware debug registers. It is done by the linux_nat_new_thread call, which is being skipped in add_lwp above for the first lwp of a pid. */ gdb_assert (num_lwps (GET_PID (child_lp->ptid)) == 1); if (linux_nat_new_thread != NULL) linux_nat_new_thread (child_lp); if (linux_nat_prepare_to_resume != NULL) linux_nat_prepare_to_resume (child_lp); ptrace (PTRACE_DETACH, child_pid, 0, 0); so unless I'm missing something (quite possible) it ends up all the same. But, the !detach-on-fork, and the "follow-fork child" paths should also call linux_nat_new_thread, and they don't presently. It seems to me in those cases we're not clearing debug regs correctly when that's needed. Instead of copying that bit that works around add_lwp bypassing the linux_nat_new_thread call, I thought it'd be better to add an add_initial_lwp call to be used in the case we really need to bypass linux_nat_new_thread, and make add_lwp always call linux_nat_new_thread. i386_cleanup_dregs is rewritten to forget about the current process debug mirrors, which takes cares of other i386 ports. Only a couple of extra tweaks here and there were needed, as some targets wheren't actually calling i386_cleanup_dregs. Tested on Fedora 17 x86_64 -m64/-m32. GDBserver already fetches the i386_debug_reg_state from the right process, and, it doesn't handle forks at all, so no fix is needed over there. gdb/ 2013-02-13 Pedro Alves <palves@redhat.com> * amd64-linux-nat.c (update_debug_registers_callback): Update comment.
