Wow, I dropped the wrong patch :( No, I don't want to carry that series, let me go rip out everything for ataflop.c now. If someone cares about this for 5.10.y, I'll take a backport series, but really, they should just go use 5.15.y instead. I'll push out a -rc4 now. thanks, greg k-h ^ permalink raw reply [flat|nested] 35+ messages in thread

Several people (incl. me) have seen the _exact same_ trace, but with BMQ/PDS (custom CPU schedulers) so we suspected a locking issue/incompatibility in get_wchan()'s spinlocking & task diddling compared to CFS. The fact that this happens with vanilla means it's a generic problem with either: "sched: Add wrapper for get_wchan() to keep task blocked" or "x86: Fix get_wchan() to support the ORC unwinder" or both. I have been running with a dummy implementation of get_wchan that just returns 0 (effectively disabling wchan) and 5.15.3-rc3 has been rock-solid again. Maybe just revert all the wchan stuff and let it stew in mainline a bit longer? -h ^ permalink raw reply [flat|nested] 35+ messages in thread

And if people see this in stable kernels, I suspect it happens in my kernel too, but there are more users of stable backports. I already complained about the locking for the get_wchan() patch for other reasons, but it looks like this is an actual unwinder problem that triggers this issue. Which I'm not AT ALL surprised about. In my locking complaint, I explicitly mentioned that we've had unwinder issues before, and that it's probably a really bad idea to call some random unwinder inside a critical lock. I really don't think the WCHAN code should use unwinders at all. It's too damn fragile, and it's too easily triggered from user space. So I think we need to revert all the wchan changes. Not just in stable, but in mainline too. And I hope people start taking the whole "unwinding is so fraught with problems that you shouldn't do it in any normal circumstances" seriously. We've had toolchain issues with unwinding markers being wrong or incomplete. We've had our own asm files not have all the proper annotations. And most importantly, we've had unwinding code that is written by people who don't take these issues seriously enough, and just blindly follow possibly corrupted or wrong pointers. Ironically, in the scheduler pull request for this all, the claim was "Make wchan() more robust". Which was very much the opposite of what it actually did.

What would be the vetted subset? :) Anyway, I have now dropped the following patches that were in the 5.15.3-rc tree: bc9bbb81730e ("x86: Fix get_wchan() to support the ORC unwinder") 42a20f86dc19 ("sched: Add wrapper for get_wchan() to keep task blocked") 5d1ceb3969b6 ("x86: Fix __get_wchan() for !STACKTRACE") And will push out another -rc release to let people test.

That looks right to me. These three were part of Peter's much larger wchan refactoring (of which 42a20f86dc19 was a core part).

OK, so the bug is firmly with 5d1ceb3969b6 ("x86: Fix __get_wchan() for !STACKTRACE") which lost the try_get_task_stack() that stack_trace_*() does.

Now on x86_64 we can __get_kernel_nofault() regs->cs and call it a day, but on i386 we have to also fetch regs->flags. Is this really the way to go? The thing is, we're already very careful about making sure the addresses are within the stack range before touching them, it's just that when we free the task stack we end up with trivially dodgy state. --- arch/x86/kernel/unwind_frame.c | 31 ++++++++++++++++++------ arch/x86/kernel/unwind_guess.c | 18 ++++++++++++-- arch/x86/kernel/unwind_orc.c | 54 +++++++++++++++++++++++++++++++++--------- 3 files changed, 83 insertions(+), 20 deletions(-) diff --git a/arch/x86/kernel/unwind_frame.c b/arch/x86/kernel/unwind_frame.c index 8e1c50c86e5d..0c5cbc8ee300 100644 --- a/arch/x86/kernel/unwind_frame.c +++ b/arch/x86/kernel/unwind_frame.c @@ -215,10 +215,11 @@ static bool update_stack_state(struct unwind_state *state, * that info->next_sp could point to an empty stack and the next bp * could be on a subsequent stack. */ - while (!on_stack(info, frame, len)) + while (!on_stack(info, frame, len)) { if (get_stack_info(info->next_sp, state->task, info, &state->stack_mask)) return false;

I tried; but at best it's fundamentally racy and in practise its worse because init_task doesn't seem to believe in refcounts and kthreads are odd for some raisin. Now those are fixable, but given the fundamental races, I don't see how it's ever going to be reliable. I don't mind the __get_kernel_nofault() usage and think I can do a better implementation that will allow us to get rid of the pagefault_{dis,en}able() sprinkling, but that's for another day. It's just the user_mode(regs) usage that's going to be somewhat ugleh. Anyway, below is the minimal fix for the situation at hand. I'm not going to be around much today, so if Linus wants to pick that up instead of mass revert things that's obviously fine too. --- Subject: x86: Pin task-stack in __get_wchan() When commit 5d1ceb3969b6 ("x86: Fix __get_wchan() for !STACKTRACE") moved from stacktrace to native unwind_*() usage, the try_get_task_stack() got lost, leading to use-after-free issues for dying tasks.

No, we want to move away from the stack_trace_*() API because it has very unclear semantics and various arch implementations differ in details. There's a patch that untangles arch_stack_walk*() from CONFIG_STACKTRACE and we can eventually use that. ^ permalink raw reply [flat|nested] 35+ messages in thread

I did have to add a number of "Link:" and "Reported-by:" etc lines though. Please try to keep those kinds around as you make patches, they get lost and forgotten too easily.

And I assume 'stack_refcount > 0' only needs to be asserted when unwinding other tasks, not current. So it shouldn't affect unwinds during boot, or oopses. Yes, the unwinder has to be rock solid, but if the caller can't even ensure the given task's memory exists, it sounds like a bug in the caller that needs a warning. -- Josh ^ permalink raw reply [flat|nested] 35+ messages in thread

We can do the warn as you suggest, however, it can become 0 right after we test and then still make the unwder explode.

Well, yes. Still it would be nice if the unwinder would not itself burn the house, even in that case. ^ permalink raw reply [flat|nested] 35+ messages in thread

Realistically there are a limited number of callers to the unwinder. If anybody calls with refcount < 2 then we can WARN() and root them out. It would have found this bug far before any weird races would have been found. True, it's not bulletproof, but task unwinder usage is (to some degree) less critical than oopses.
