Linus Torvalds e7ddacf62c x86/mm: Remove broken vsyscall emulation code from the page fault code 
commit 02b670c1f88e78f42a6c5aee155c7b26960ca054 upstream.

The syzbot-reported stack trace from hell in this discussion thread
actually has three nested page faults:

  https://lore.kernel.org/r/000000000000d5f4fc0616e816d4@google.com

... and I think that's actually the important thing here:

 - the first page fault is from user space, and triggers the vsyscall
   emulation.

 - the second page fault is from __do_sys_gettimeofday(), and that should
   just have caused the exception that then sets the return value to
   -EFAULT

 - the third nested page fault is due to _raw_spin_unlock_irqrestore() ->
   preempt_schedule() -> trace_sched_switch(), which then causes a BPF
   trace program to run, which does that bpf_probe_read_compat(), which
   causes that page fault under pagefault_disable().

It's quite the nasty backtrace, and there's a lot going on.

The problem is literally the vsyscall emulation, which sets

        current->thread.sig_on_uaccess_err = 1;

and that causes the fixup_exception() code to send the signal *despite* the
exception being caught.

And I think that is in fact completely bogus.  It's completely bogus
exactly because it sends that signal even when it *shouldn't* be sent -
like for the BPF user mode trace gathering.

In other words, I think the whole "sig_on_uaccess_err" thing is entirely
broken, because it makes any nested page-faults do all the wrong things.

Now, arguably, I don't think anybody should enable vsyscall emulation any
more, but this test case clearly does.

I think we should just make the "send SIGSEGV" be something that the
vsyscall emulation does on its own, not this broken per-thread state for
something that isn't actually per thread.

The x86 page fault code actually tried to deal with the "incorrect nesting"
by having that:

                if (in_interrupt())
                        return;

which ignores the sig_on_uaccess_err case when it happens in interrupts,
but as shown by this example, these nested page faults do not need to be
about interrupts at all.

IOW, I think the only right thing is to remove that horrendously broken
code.

The attached patch looks like the ObviouslyCorrect(tm) thing to do.

NOTE! This broken code goes back to this commit in 2011:

  4fc3490114bb ("x86-64: Set siginfo and context on vsyscall emulation faults")

... and back then the reason was to get all the siginfo details right.
Honestly, I do not for a moment believe that it's worth getting the siginfo
details right here, but part of the commit says:

    This fixes issues with UML when vsyscall=emulate.

... and so my patch to remove this garbage will probably break UML in this
situation.

I do not believe that anybody should be running with vsyscall=emulate in
2024 in the first place, much less if you are doing things like UML. But
let's see if somebody screams.

[gpiccoli: Backport the patch due to differences in the trees. The main change
 between 5.10.y and 5.15.y is due to renaming the fixup function, by
 commit 6456a2a69ee1 ("x86/fault: Rename no_context() to kernelmode_fixup_or_oops()").
 Following 2 commits cause divergence in the diffs too (in the removed lines):
 cd072dab453a ("x86/fault: Add a helper function to sanitize error code")
 d4ffd5df9d18 ("x86/fault: Fix wrong signal when vsyscall fails with pkey")
 Finally, there is context adjustment in the processor.h file.]
