[Qemu-devel] system_reset command cause assert failed

[Qemu-devel] system_reset command cause assert failed

[Roy Tam]

Dear all,

In latest git revision, when guest OS restarts or system_reset command
issues from monitor console, it asserts failed:
Assertion failed: obj != NULL, file C:/msys/home/User/qemu/monitor.c, line 338

Best regards,
Roy Tam

 Hm, I can't reproduce this on Linux. Can you, please provide a backtrace and
your git HEAD?

 Thanks.

 Still no fun. It's possible that there's something windows-specific
that makes qobject_from_jsonf() return NULL.

 Without a backtrace my only option is to install windows on
some machine here and try to reproduce the problem, but this will take
some time.

 Hm, I'm puzzled. Is this failing on malloc()? At least qemu_malloc()
is the last qemu's function I see in the logs.

 From now on I only see msvcrt functions...

 Maybe, you can type run on gdb, run system_reset on the
Monitor and then switch back to gdb and type bt?

 As far as I can understand something bad happens while the parser
is processing the first "'" character of the qobject_from_jsonf()
call in monitor.c:4524.

Do they work?

 Maybe this is a refcount problem?

 Ok, so we have a double free and

 a segfault.

 I don't know what's happening, I'll have to run QEMU on windows and
try to reproduce it.

Clarify that after digging into sources further, it is not double
free, but parse_json not be executed by json_lexer_feed_char as I put
asm("int3") in parse_json but there's no SIGTRAP be raised. (for
system_reset and system_powerdown)

for this, parse_json was executed by json_lexer_feed_char.
a workaround patch is here, but why null qobj has pushed into qlist?

 Well, I think I'll only have time to setup this stuff on windows
in two or three days :(

 Yeah, that's the question and I'm afraid that this patch will
actually hide the real bug.

 You can do two things:

1. Put an assert() at qlist.c:qlist_append_obj()
2. Reset your tree to commit 0a7fc983ce and send me the output of
   'info pci'

qobject_from_jsonf() fails? then it may be same of
