4Subject: [PATCH] vnc: fix memory leak when vnc disconnect
5
6Currently when qemu receives a vnc connect, it creates a 'VncState' to
7represent this connection. In 'vnc_worker_thread_loop' it creates a
8local 'VncState'. The connection 'VcnState' and local 'VncState' exchange
9data in 'vnc_async_encoding_start' and 'vnc_async_encoding_end'.
10In 'zrle_compress_data' it calls 'deflateInit2' to allocate the libz library
11opaque data. The 'VncState' used in 'zrle_compress_data' is the local
12'VncState'. In 'vnc_zrle_clear' it calls 'deflateEnd' to free the libz
13library opaque data. The 'VncState' used in 'vnc_zrle_clear' is the connection
14'VncState'. In currently implementation there will be a memory leak when the
15vnc disconnect. Following is the asan output backtrack:
16
17Direct leak of 29760 byte(s) in 5 object(s) allocated from:
18 0 0xffffa67ef3c3 in __interceptor_calloc (/lib64/libasan.so.4+0xd33c3)
19 1 0xffffa65071cb in g_malloc0 (/lib64/libglib-2.0.so.0+0x571cb)
20 2 0xffffa5e968f7 in deflateInit2_ (/lib64/libz.so.1+0x78f7)
21 3 0xaaaacec58613 in zrle_compress_data ui/vnc-enc-zrle.c:87
22 4 0xaaaacec58613 in zrle_send_framebuffer_update ui/vnc-enc-zrle.c:344
23 5 0xaaaacec34e77 in vnc_send_framebuffer_update ui/vnc.c:919
24 6 0xaaaacec5e023 in vnc_worker_thread_loop ui/vnc-jobs.c:271
25 7 0xaaaacec5e5e7 in vnc_worker_thread ui/vnc-jobs.c:340
26 8 0xaaaacee4d3c3 in qemu_thread_start util/qemu-thread-posix.c:502
27 9 0xffffa544e8bb in start_thread (/lib64/libpthread.so.0+0x78bb)
28 10 0xffffa53965cb in thread_start (/lib64/libc.so.6+0xd55cb)
29
30This is because the opaque allocated in 'deflateInit2' is not freed in
31'deflateEnd'. The reason is that the 'deflateEnd' calls 'deflateStateCheck'
32and in the latter will check whether 's->strm != strm'(libz's data structure).
33This check will be true so in 'deflateEnd' it just return 'Z_STREAM_ERROR' and
34not free the data allocated in 'deflateInit2'.
35
36The reason this happens is that the 'VncState' contains the whole 'VncZrle',
37so when calling 'deflateInit2', the 's->strm' will be the local address.
38So 's->strm != strm' will be true.
39
40To fix this issue, we need to make 'zrle' of 'VncState' to be a pointer.
41Then the connection 'VncState' and local 'VncState' exchange mechanism will
42work as expection. The 'tight' of 'VncState' has the same issue, let's also turn
43it to a pointer.
