Is there any change to get disassembly of console_unlock() from the
problematic build?
I have troubles to reproduce this myself. Also I was not able to find any
bug just by looking into the code yet. The disassembly might help
a lot here.
Interesting symptoms (for myself and other debuggers):
The lines are duplicated. Therefore it happened when real
console was registered and before the early console was unregistered.
See also the full dmesg for these actions. The related printk messages
are right after the KASAN report.
I wonder if it is unsafe to pass the console_lock via
console_trylock_spinnning() from console_unlock() called
in register_console(). I do not see any problem but I might
be blind.
Another interesting thing is that the entire KASAN report is
duplicated. I wonder if it is a two level duplication or
if the BUG() was really triggered twice.

Also the job-script was not attached. Is it because the problem
happened already during the boot?
Thanks for the report.
Best Regards,
Petr

The KASAN report is between the following lines in dmesg:
[ 0.003333] Offload RCU callbacks from CPUs: .
[ 0.003333] ==================================================================
[ 0.003333] ==================================================================
[ 0.003333] BUG: KASAN: use-after-scope in console_unlock+0x185/0x960
[ 0.003333] BUG: KASAN: use-after-scope in console_unlock+0x185/0x960
[...]
[ 0.003333] console [ttyS0] enabled
The first message is printed from rcu_init_nohz().
The last message is printed from register_console().
I would expect that the KASAN message is triggered from the following
code:
rcu_init_nohz();
init_timers();
hrtimers_init();
softirq_init();
timekeeping_init();
time_init();
sched_clock_postinit();
printk_safe_init();
perf_event_init();
profile_init();
call_function_init();
WARN(!irqs_disabled(), "Interrupts were enabled early\n");
early_boot_irqs_disabled = false;
local_irq_enable();
kmem_cache_init_late();
/*
* HACK ALERT! This is early. We're enabling the console before
* we've done PCI setups etc, and console_init() must be aware of
* this. But we do want output early, in case something goes wrong.
*/
console_init();
I am just confused that I do not see any of this function on the
stack. Note that this code is still called in the single CPU mode.
I feel lost a bit.
I am really curious what code is proceed on the line
console_unlock+0x185/0x960.

Petr

I'm not sure it we actually have concurrent printks at that state yet,
might be too early for any printk offloading. The backtrace still
makes no sense to me at all, tho. We had this report twice, probably,
already (even before the offloading patchset, if I'm not mistaken).

Yeah... can't understand what's going on there.
The last time kasan didn't like this part
[ 0.003333] ? console_unlock+0x605/0xcc0:
atomic_read at arch/x86/include/asm/atomic.h:27
(inlined by) static_key_count at include/linux/jump_label.h:191

complaining that there was a write of size 4... at atomic_read().
Now it's reporting that the write of size 1 was out of scope.

Agreed.
On my system 0x185/0x960 is somewhere around
191e: 89 d7 mov %edx,%edi
1920: e8 06 e7 ff ff callq 2b <log_next>
1925: 48 89 2d 00 00 00 00 mov %rbp,0x0(%rip) # 192c <console_unlock+0x17f>
192c: 89 05 00 00 00 00 mov %eax,0x0(%rip) # 1932 <console_unlock+0x185>
>> 1932: eb a9 jmp 18dd <console_unlock+0x130>
1934: 8b 35 00 00 00 00 mov 0x0(%rip),%esi # 193a <console_unlock+0x18d>
193a: b9 00 04 00 00 mov $0x400,%ecx
193f: 4c 89 ef mov %r13,%rdi
1942: 31 ed xor %ebp,%ebp
That jmp 18dd after log_next() is a `goto skip' in
suppress_message_printing() branch
skip:
if (console_seq == log_next_seq)
break;
msg = log_from_idx(console_idx);
if (suppress_message_printing(msg->level)) {
/*
* Skip record we have buffered and already printed
* directly to the console when we received it, and
* record that has level above the console loglevel.
*/
console_idx = log_next(console_idx);
console_seq++;
>> goto skip;
}
As far as I can tell.

Hi Shun,
The report says "job-script is attached in this email", but I don't
see it attached. Did you forget to attach it? How can I reproduce this
exact build?
Could you post a symbolized report with inlines frames?

Hi Sergey,
Where is that report?
I doubt that KASAN has instrumented a read as a write (at least there
are no such known cases), so perhaps it's pointing to some other
memory access.

For a KASAN report IP must point to one of __asan_[report_]load/store function.

I can reproduce this warning with VMware environment.
Something is happening inside __asan_store1() before calling raw_spin_lock(&console_owner_lock) ?

Interesting thing is that as of commit 97ace515f01439d4 on linux.git, there is no
such __asan_store1() before calling raw_spin_lock(&console_owner_lock) and hence
cannot reproduce this warning. Maybe a KASAN bug as of commit c162d5b4338d72de ?

+Ard, Kees
This is a problem with GCC_PLUGIN_STRUCTLEAK_BYREF_ALL. It inserts an
initializing write for __u used in READ_ONCE outside of live scope of
the variable.
Below "movb $0x1,0x0(%r13)" and "movb $0xf8,0x0(%r13)" denote live
scope of the variable __u (the 0xf8 that appears in the KASAN report).
But the initializing store at ffffffff811a5f84 (and the corresponding
KASAN check) are outside of that scope, which causes the KASAN report.

We either need to fix GCC_PLUGIN_STRUCTLEAK_BYREF_ALL (and probably
GCC_PLUGIN_STRUCTLEAK) to insert initialization at proper places or
run before KASAN instrumentation (though, since the initializing
stores are instrumented, it already runs partially before KASAN), or
declare GCC_PLUGIN_STRUCTLEAK incompatible with KASAN (it's not the
first time we debug this).

I am pretty sure that this is a fundamental issue with the plugin, and
not specific to BYREF_ALL. BYREF_ALL just increases the number of
occurrences, making it easier to hit this issue.
I'd be fine with making the plugin mutually exclusive with KASAN.

Thanks, but now that I debugged this one, I think that one is the same issue.
Amusingly a write in READ_ONCE is actually legitimate because
GCC_PLUGIN_STRUCTLEAK emits an initializing write for __u variable in
READ_ONCE implementation.

I'm fine making it mutally exclusive: it forces KASAN to run without
the protections the plugin provides, so really, that's better to test
(i.e. the plugin could cover up bugs that KASAN might otherwise find).
