Title: Snippet
|
I developed a Windows-based (using VS2010) server application using
the 0.6.0rc1 version of libssh and was getting memory leaks on a per
connection basis. I decided to migrate to the latest version (0.6.4)
to see if it alleviated these leaks and ran into different issues.
The first issue is in socket.c starting at line 314.
ssh_socket_set_blocking() is failing and WSAGetLastError() is
returning 10022 (WSAEINVAL). Since sockets are initially in blocking
mode ("When a socket is created, it operates in blocking mode by
default (nonblocking mode is disabled). This is consistent with
BSD sockets." -
https://msdn.microsoft.com/en-us/library/windows/desktop/ms738573(v=vs.85).aspx),
I commented out the section of code to get passed the error. Now,
during the key exchange, clients (putty), disconnects with "Incoming
packet was garbled on decryption". Below is a log I collected. 2015-04-06 18:09:35 SYS-INF DAEMON - NEW CONNECTION FROM 192.168.1.206:16907 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_socket_pollcallback(3) - ssh_socket_pollcallback: Received POLLOUT in connecting state 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_socket_unbuffered_write(3) - ssh_socket_unbuffered_write: Enabling POLLOUT for socket 2015-04-06 18:09:35 ACT-INF DAEMON - callback_receive_banner(3) - callback_receive_banner: Received banner: SSH-2.0-PuTTY_Local:_Aug__7_2013_13:47:56 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_server_connection_callback(1) - ssh_server_connection_callback: SSH client banner: SSH-2.0-PuTTY_Local:_Aug__7_2013_13:47:56 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_analyze_banner(1) - ssh_analyze_banner: Analyzing banner: SSH-2.0-PuTTY_Local:_Aug__7_2013_13:47:56 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_list_kex(4) - ssh_list_kex: kex algos: curve25519-sha256@xxxxxxxxxx,ecdh-sha2-nistp256,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_list_kex(4) - ssh_list_kex: server host key algo: ssh-dss,ssh-rsa 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_list_kex(4) - ssh_list_kex: encryption client->server: aes256-ctr,aes192-ctr,aes128-ctr,aes256-cbc,aes192-cbc,aes128-cbc,blowfish-cbc,3des-cbc,des-cbc-ssh1 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_list_kex(4) - ssh_list_kex: encryption server->client: aes256-ctr,aes192-ctr,aes128-ctr,aes256-cbc,aes192-cbc,aes128-cbc,blowfish-cbc,3des-cbc,des-cbc-ssh1 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_list_kex(4) - ssh_list_kex: mac algo client->server: hmac-sha1 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_list_kex(4) - ssh_list_kex: mac algo server->client: hmac-sha1 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_list_kex(4) - ssh_list_kex: compression algo client->server: none,zlib,zlib@xxxxxxxxxxx 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_list_kex(4) - ssh_list_kex: compression algo server->client: none,zlib,zlib@xxxxxxxxxxx 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_list_kex(4) - ssh_list_kex: languages client->server: 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_list_kex(4) - ssh_list_kex: languages server->client: 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_socket_unbuffered_write(3) - ssh_socket_unbuffered_write: Enabling POLLOUT for socket 2015-04-06 18:09:35 ACT-INF DAEMON - packet_send2(3) - packet_send2: packet: wrote [len=460,padding=10,comp=449,payload=449] 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_socket_exception_callback(1) - ssh_socket_exception_callback: Socket exception callback: 2 (10053) 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_socket_exception_callback(1) - ssh_socket_exception_callback: Socket error: Unknown error 2015-04-06 18:09:35 ACT-INF DAEMON - ssh_handle_key_exchange(3) - ssh_handle_key_exchange: ssh_handle_key_exchange: current state : 9 2015-04-06 18:09:35 ACT-INF 192.168.1.206:16907 - ERROR (-1) ON KEY EXCHANGE: Socket error: Unknown error Attached is the putty log file. --
