I have implemented it as a standard server, where a thread opens the forwarded port for listening and on connection launches another thread to deal with it (It is important for http requests where many requests are made simultaneously) I got many crashes inside libssh2, even after implementing CRYPTO_set_locking_callback, and after intense googling, it seemed I had to implement it so that I had a unique valid session per thread. It now works beautifully. But I have hit another problem, each thread having its own session means that each thread needs to authenticate with the ssh server independently, and if several requests are made quickly, then some get rejected by the server's firewall for suspected DOS attack. (I have a thread pool of 4 threads, 4 requests within the same couple of seconds and I get rejected). Now, have I missed something? Could one 'main' session be used to authenticate and then be cloned for each subsequent thread?

I'm attaching a patch for review, as I'm not completely certain about some of the error paths. The first is in _libssh2_packet_add. This error path does not satisfy the function's documented constraint: * The input pointer 'data' is pointing to allocated data that this function * is asked to deal with so on failure OR success, it must be freed fine. i.e. it never gets freed. However, my fix for this completely drops the data buffer. I suspect that this could result in a protocol violation or data if libssh2 would continue to operate. If so, then it should probably be documented that upon receipt of a LIBSSH2_ERROR_ALLOC error, the application should immediately clean up the session. It's likely there are other OOM error paths where this could also be a problem. The second error results when a session is torn down prematurely, while a transport payload is fully processed. There is currently no path to free this buffer when the session is torn down, so I added one. The third error isn't an OOM problem, but a potentially more serious use-after-free one. There seems to be a path through _libssh2_transport_read where this could occur. If the call to fullpacket results in LIBSSH2_ERROR_EAGAIN, it must have come from _libssh2_packet_add, which as previously discussed, always frees (or takes ownership of) its data argument. However, the path ending in line 578 of transport.c does not reset total_num, which is used to indicate whether payload has been allocated or not. That means that the buffer was added to the brigade, but could still be written into in future calls to _libssh2_transport_read. What I'm not certain about is whether or not fullpacket() guarantees freeing or taking ownership of p->payload. There is a path through fullpacket() where that could occur; I just don't know if it could logically occur. If it could, then moving the total_num=0 line up as I have isn't quite right. >>> Dan --HlL+5n6rz5pIUxbD Content-Type: text/plain; charset=iso-8859-1 Content-Disposition: attachment; filename="0001-Fixed-a-few-memory-leaks-in-out-of-memory-paths.patch" Content-Transfer-Encoding: quoted-printable =46rom 05c51895b55169c68bc0191c94d3769d09de5504 Mon Sep 17 00:00:00 2001 =46rom: Dan Fandrich Date: Thu, 6 Feb 2014 23:10:53 +0100 Subject: [PATCH] Fixed a few memory leaks in out-of-memory paths Also fixed a potential use-after-free. --- src/packet.c | 1 + src/session.c | 5 +++++ src/transport.c | 3 +-- 3 files changed, 7 insertions(+), 2 deletions(-) diff --git a/src/packet.c b/src/packet.c index 47bbf2b..9d937e3 100644 --- a/src/packet.c +++ b/src/packet.c @@ -967,6 +967,7 @@ _libssh2_packet_add(LIBSSH2_SESSION * session, unsigned= char *data, if (!packetp) { _libssh2_debug(session, LIBSSH2_ERROR_ALLOC, "memory for packet"); + LIBSSH2_FREE(session, data); session->packAdd_state =3D libssh2_NB_state_idle; return LIBSSH2_ERROR_ALLOC; } diff --git a/src/session.c b/src/session.c index 9838d2b..3a52fd4 100644 --- a/src/session.c +++ b/src/session.c @@ -1017,6 +1017,11 @@ session_free(LIBSSH2_SESSION *session) LIBSSH2_FREE(session, session->scpSend_command); } =20 + /* Free payload buffer */ + if (session->packet.total_num) { + LIBSSH2_FREE(session, session->packet.payload); + } + /* Cleanup all remaining packets */ while ((pkg =3D _libssh2_list_first(&session->packets))) { packets_left++; diff --git a/src/transport.c b/src/transport.c index b4ec037..8ba34e1 100644 --- a/src/transport.c +++ b/src/transport.c @@ -559,6 +559,7 @@ int _libssh2_transport_read(LIBSSH2_SESSION * session) /* we have a full packet */ libssh2_transport_read_point1: rc =3D fullpacket(session, encrypted); + p->total_num =3D 0; /* no packet buffer available */ if (rc =3D=3D LIBSSH2_ERROR_EAGAIN) { =20 if (session->packAdd_state !=3D libssh2_NB_state_idle) @@ -578,8 +579,6 @@ int _libssh2_transport_read(LIBSSH2_SESSION * session) return rc; } =20 - p->total_num =3D 0; /* no packet buffer available */ - return rc; } } while (1); /* loop */ --=20 1.8.1.5 --HlL+5n6rz5pIUxbD Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel --HlL+5n6rz5pIUxbD-- From libssh2-devel-bounces@cool.haxx.se Tue Feb 11 10:48:00 2014 Return-Path: Received: from www.haxx.se (list@localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-4.1) with ESMTP id s1B9lRQl001362; Tue, 11 Feb 2014 10:47:53 +0100 Received: from earth.stuge.se (earth.stuge.se [212.116.89.126]) by giant.haxx.se (8.14.4/8.14.4/Debian-4.1) with ESMTP id s1B9lLNw001301 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-GCM-SHA384 bits=256 verify=NOT) for ; Tue, 11 Feb 2014 10:47:21 +0100 Received: (qmail 29180 invoked from network); 11 Feb 2014 09:39:19 -0000 Received: from unknown (HELO earth.stuge.se) (127.0.0.1) by localhost with SMTP; 11 Feb 2014 09:39:19 -0000 MIME-Version: 1.0 From: "libssh2 Trac" X-Trac-Version: 1.0dev Precedence: bulk Auto-Submitted: auto-generated X-Mailer: Trac 1.0dev, by Edgewall Software To: wang4585_001@163.com X-Trac-Project: libssh2 Date: Tue, 11 Feb 2014 09:39:19 -0000 X-URL: https://trac.libssh2.org/ Subject: [libssh2] #285: multithread calls libssh2.a error X-Trac-Ticket-URL: https://trac.libssh2.org/ticket/285 Message-ID: <047.96e14ff308d3aef6124dae1272948e70@libssh2.stuge.se> X-Trac-Ticket-ID: 285 X-MIME-Autoconverted: from base64 to 8bit by giant.haxx.se id s1B9lLNw001301 Cc: libssh2-devel@cool.haxx.se X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.16 Reply-To: trac@libssh2.stuge.se, libssh2 development List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: libssh2-devel-bounces@cool.haxx.se Sender: "libssh2-devel" #285: multithread calls libssh2.a error -----------------------------------------------------+-------------------- Reporter: beiguan001 | Owner: Type: defect | Status: new Priority: high | Milestone: 1.4.3 Component: API | Version: 1.4.2 Keywords: multi-thread libssh2_session_handshake | Blocked By: Blocks: | -----------------------------------------------------+-------------------- When using multiple threads, in libssh2_session_handshake abnormal.

I'm developing a proj= ect witch a little linux device, connects to other devices running Openwrt = via SSH.

It works pretty well, but some times, I get an error = LIBSSH2_ERROR_TIMEOUT

I don't think the problem is timeout related,=20 because the remote device is most of the time idle, and the connectivity is good. =BFwhat else could trigger this error??

Thanks! :)<= /div> --bcaec50161f378477304f21f44eb-- --===============0271020810== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel --===============0271020810==-- From libssh2-devel-bounces@cool.haxx.se Tue Feb 11 20:04:04 2014 Return-Path: Received: from www.haxx.se (list@localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-4.1) with ESMTP id s1BJ3aYR028646; Tue, 11 Feb 2014 20:03:58 +0100 Received: from foo.stuge.se (qmailr@foo.stuge.se [212.116.89.98]) by giant.haxx.se (8.14.4/8.14.4/Debian-4.1) with ESMTP id s1BJ3WQ4028547 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-GCM-SHA384 bits=256 verify=NOT) for ; Tue, 11 Feb 2014 20:03:32 +0100 Received: (qmail 24404 invoked by uid 501); 11 Feb 2014 19:03:33 -0000 Message-ID: <20140211190333.24403.qmail@stuge.se> Date: Tue, 11 Feb 2014 20:03:33 +0100 From: Peter Stuge To: libssh2-devel@cool.haxx.se Subject: Re: LIBSSH2_ERROR_TIMEOUT Mail-Followup-To: libssh2-devel@cool.haxx.se References: MIME-Version: 1.0 Content-Disposition: inline In-Reply-To: X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.16 Precedence: list Reply-To: libssh2 development List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: libssh2-devel-bounces@cool.haxx.se Sender: "libssh2-devel" vicent roca daniel wrote: > I get an error LIBSSH2_ERROR_TIMEOUT > I don't think the problem is timeout related You probably understand how silly this seems. Please do investigate what the actual cause of your problem is and get back to the list. Do some debugging before posting. Nobody can do that for you. The library has verboseish tracing and you can use strace and other system tools. Please let us know what you find. //Peter _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Tue Feb 11 23:15:55 2014 Return-Path: Received: from www.haxx.se (list@localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-4.1) with ESMTP id s1BMFYFs014866; Tue, 11 Feb 2014 23:15:52 +0100 Received: from earth.stuge.se (earth.stuge.se [212.116.89.126]) by giant.haxx.se (8.14.4/8.14.4/Debian-4.1) with ESMTP id s1BMFXZc014815 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-GCM-SHA384 bits=256 verify=NOT) for ; Tue, 11 Feb 2014 23:15:33 +0100 Received: (qmail 8662 invoked from network); 11 Feb 2014 22:14:13 -0000 Received: from unknown (HELO earth.stuge.se) (127.0.0.1) by localhost with SMTP; 11 Feb 2014 22:14:13 -0000 MIME-Version: 1.0 From: "libssh2 Trac" X-Trac-Version: 1.0dev Precedence: bulk Auto-Submitted: auto-generated X-Mailer: Trac 1.0dev, by Edgewall Software To: wang4585_001@163.com, daniel@haxx.se X-Trac-Project: libssh2 Date: Tue, 11 Feb 2014 22:14:13 -0000 X-URL: https://trac.libssh2.org/ Subject: Re: [libssh2] #285: multithread calls libssh2.a error X-Trac-Ticket-URL: https://trac.libssh2.org/ticket/285#comment:1 Message-ID: <062.f005530a51d6835078cdcc0f0b27fdaa@libssh2.stuge.se> References: <047.96e14ff308d3aef6124dae1272948e70@libssh2.stuge.se> X-Trac-Ticket-ID: 285 In-Reply-To: <047.96e14ff308d3aef6124dae1272948e70@libssh2.stuge.se> X-MIME-Autoconverted: from base64 to 8bit by giant.haxx.se id s1BMFXZc014815 Cc: libssh2-devel@cool.haxx.se X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.16 Reply-To: trac@libssh2.stuge.se, libssh2 development List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: libssh2-devel-bounces@cool.haxx.se Sender: "libssh2-devel" #285: multithread calls libssh2.a error -------------------------+------------------------------------------------- Reporter: beiguan001 | Owner: Type: defect | Status: closed Priority: high | Milestone: 1.4.3 Component: API | Version: 1.4.2 Resolution: invalid | Keywords: multi-thread Blocked By: | libssh2_session_handshake | Blocks: -------------------------+------------------------------------------------- Changes (by bagder): * status: new => closed * resolution: => invalid Comment: This is a bug tracker where we track and work with bugs.

At a quick glance, the OP's code doesn't share sessions between threads, so it's more likely an issue with multiple threads calling the crypto backend. In particular libssh2_init is not thread safe, but the OP calls this in the worker thread. Instead they should call it once for the entire program before spawning any worker threads.

How to use multi-thread calls libssh2? > I had a similar problem. Perhaps my solution can you help as well. If I created a session I got the error: Unable to exchange encryption keys I enabled verbose logging and did run the application with truss (similar to strace on Linux) on Solaris. /13: recv(11, 0xFFFFFD7FFBA05B17, 1, 0) Err#11 EAGAIN _libssh2_recv: rc=-1 errno=125 [libssh2] 0.758411 Socket: Error recving 1 bytes: 125 On the first line above a recv() system call returned with -1 and errno was 11 (EAGAIN). But on the second and third line errno was 125. The second line is a debug output which I added to the source directly after the recv() statement. The source of the problem was that I didn't compile libssh2 with correct compiler flags for multi-threading. If you do not pay attention on Solaris then errno is a global variable. Using gcc compiler you can add "-pthread" as compile and link flag to enable thread local storage of errno. Using -D_REENTRANT on Solaris as compile flag also works. My configure call is now is e.g. CFLAGS="-m64 -pthread" LDFLAGS="-m64 -pthread" ./configure --with-openssl --with-libssl-prefix=$HOME/local --with-libz --with-libz-prefix=$HOME/local

There is a search box on the gmane link on the mailing list archive page, or you could just Google it with a site:libssh2.org query modifier. The latter could easily be added to the archive page as well by the site owner. >>> Dan _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Mon Feb 17 22:41:37 2014 Return-Path: Received: from www.haxx.se (list@localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-4.1) with ESMTP id s1HLfIgS018711; Mon, 17 Feb 2014 22:41:34 +0100 Received: from giant.haxx.se (dast@localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-4.1) with ESMTP id s1HLfHPo018696 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-GCM-SHA384 bits=256 verify=NOT) for ; Mon, 17 Feb 2014 22:41:17 +0100 Received: from localhost (dast@localhost) by giant.haxx.se (8.14.4/8.14.4/Submit) with ESMTP id s1HLfHGv018660 for ; Mon, 17 Feb 2014 22:41:17 +0100 X-Authentication-Warning: giant.haxx.se: dast owned process doing -bs Date: Mon, 17 Feb 2014 22:41:17 +0100 (CET) From: Daniel Stenberg X-X-Sender: dast@giant.haxx.se To: libssh2 development Subject: Re: How to search the mail list archives?

There's now a search bar at the bottom of each page on the site that allows you to search the site and its mail archives. -- / daniel.haxx.se _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel From libssh2-devel-bounces@cool.haxx.se Tue Feb 25 00:54:54 2014 Return-Path: Received: from www.haxx.se (list@localhost.localdomain [127.0.0.1]) by giant.haxx.se (8.14.4/8.14.4/Debian-4.1) with ESMTP id s1ONsOSD032602; Tue, 25 Feb 2014 00:54:48 +0100 Received: from colibri.localdomain (ppp-93-104-32-175.dynamic.mnet-online.de [93.104.32.175]) by giant.haxx.se (8.14.4/8.14.4/Debian-4.1) with ESMTP id s1ONsMYu032595 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-GCM-SHA384 bits=256 verify=NOT) for ; Tue, 25 Feb 2014 00:54:22 +0100 Received: by colibri.localdomain (Postfix, from userid 501) id 7B0F17B0B3; Tue, 25 Feb 2014 00:54:23 +0100 (CET) Date: Tue, 25 Feb 2014 00:54:23 +0100 From: Dan Fandrich To: libssh2-devel@cool.haxx.se Subject: Re: Memory leaks in out-of-memory conditions Message-ID: <20140224235423.GA9245@coneharvesters.com> Mail-Followup-To: libssh2-devel@cool.haxx.se References: <20140206224853.GA31754@coneharvesters.com> MIME-Version: 1.0 Content-Disposition: inline In-Reply-To: <20140206224853.GA31754@coneharvesters.com> User-Agent: Mutt/1.5.21 (2010-09-15) X-BeenThere: libssh2-devel@cool.haxx.se X-Mailman-Version: 2.1.16 Precedence: list Reply-To: libssh2 development List-Id: libssh2 development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: libssh2-devel-bounces@cool.haxx.se Sender: "libssh2-devel" On Thu, Feb 06, 2014 at 11:48:53PM +0100, Dan Fandrich wrote: > I've discovered a few memory leaks in libssh2, while running the curl torture > tests.

I studied this in more depth and found my original understanding (and the comments) weren't quite right on one issue. I've pushed a change that I'm more comfortable with, as well as fixing a number of other error path problems I found. >>> Dan _______________________________________________ libssh2-devel http://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel
