Alex Chen 922d42bb0d json: Fix a memleak in parse_pair() In qobject_type(), NULL is returned when the 'QObject' returned from parse_value() is not of QString type, and this 'QObject' memory will leaked. So we need to first cache the 'QObject' returned from parse_value(), and finally free 'QObject' memory at the end of the function. Also, we add a testcast about invalid dict key. The memleak stack is as follows: Direct leak of 32 byte(s) in 1 object(s) allocated from: #0 0xfffe4b3c34fb in __interceptor_malloc (/lib64/libasan.so.4+0xd34fb) #1 0xfffe4ae48aa3 in g_malloc (/lib64/libglib-2.0.so.0+0x58aa3) #2 0xaaab3557d9f7 in qnum_from_int qemu/qobject/qnum.c:25 #3 0xaaab35584d23 in parse_literal qemu/qobject/json-parser.c:511 #4 0xaaab35584d23 in parse_value qemu/qobject/json-parser.c:554 #5 0xaaab35583d77 in parse_pair qemu/qobject/json-parser.c:270 #6 0xaaab355845db in parse_object qemu/qobject/json-parser.c:327 #7 0xaaab355845db in parse_value qemu/qobject/json-parser.c:546 #8 0xaaab35585b1b in json_parser_parse qemu/qobject/json-parser.c:580 #9 0xaaab35583703 in json_message_process_token qemu/qobject/json-streamer.c:92 #10 0xaaab355ddccf in json_lexer_feed_char qemu/qobject/json-lexer.c:313 #11 0xaaab355de0eb in json_lexer_feed qemu/qobject/json-lexer.c:350 #12 0xaaab354aff67 in tcp_chr_read qemu/chardev/char-socket.c:525 #13 0xfffe4ae429db in g_main_context_dispatch (/lib64/libglib-2.0.so.0+0x529db) #14 0xfffe4ae42d8f (/lib64/libglib-2.0.so.0+0x52d8f) #15 0xfffe4ae430df in g_main_loop_run (/lib64/libglib-2.0.so.0+0x530df) #16 0xaaab34d70bff in iothread_run qemu/iothread.c:82 #17 0xaaab3559d71b in qemu_thread_start qemu/util/qemu-thread-posix.c:519 Fixes: `532fb53284` ("qapi: Make more of qobject_to()") Reported-by: Euler Robot <euler.robot@huawei.com> Signed-off-by: Alex Chen <alex.chen@huawei.com> Signed-off-by: Chen Qun <kuhn.chenqun@huawei.com> Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20201113145525.85151-1-alex.chen@huawei.com> [Commit message tweaked]		5 years ago
